What are the differences and similarity between action potential and graded potential?
Help please
Answer:
Depending on the stimulus, graded potentials can be depolarizing or hyperpolarizing. Action potentials always lead to depolarization of membrane and reversal of the membrane potential. Amplitude is proportional to the strength of the stimulus. ... Duration of graded potentials may be a few milliseconds to seconds.

Describe the difference between normal vision and colorblindness. Do individuals with red/green colorblindness have difficulty seeing at night? Why or why not?
Answer:
Color vision is possible due to photoreceptors in the retina of the eye known as cones. These cones have light-sensitive pigments that enable us to recognize color. Found in the macula (the central part of the retina), each cone is sensitive to either red, green or blue light (long, medium or short wavelengths). The cones recognize these lights based on their wavelengths. Normally, the pigments inside the cones register different colors and send that information through the optic nerve to the brain. This enables us to distinguish countless shades of color. But if the cones don't have one or more light-sensitive pigments, they will be unable to see all colors.
Most people with color vision deficiency can see colors. The most common form of color deficiency is red-green. This does not mean that people with this deficiency cannot see these colors altogether, they simply have a harder time differentiating between them, which can depend on the darkness or lightness of the colors.
Another form of color deficiency is blue-yellow. This is a rarer and more severe form of color vision loss than just red-green deficiency because people with blue-yellow deficiency frequently have red-green blindness, too. In both cases, people with color-vision deficiency often see neutral or gray areas where color should appear.
People who are totally color deficient, a condition called achromatopsia, can only see things as black and white or in shades of gray. Color vision deficiency can range from mild to severe, depending on the cause. It affects both eyes if it is inherited and usually just one if it is caused by injury or illness.

"The gross primary productivity of a meadow in southeastern Kansas is found to be 38,000 kcal/m 2 . Respiration which is measured by the amount of CO 2 released is 13,500 kcal/m 2 , what is the net primary productivity for this ecosystem, in kcal/m 2 per year
Answer:
Net primary productivity = 24,500 kcal/m²
Explanation:
Given:
Gross primary productivity = 38,000 kcal/m²
Respiration amount = 13,500 kcal/m²
Find:
Net primary productivity
Computation:
Net primary productivity = Gross primary productivity - Respiration amount
Net primary productivity = 38,000 - 13,500
Net primary productivity = 24,500 kcal/m²

The correct order of replication are DNA unwinds then the The hydrogen bonds are broken between the nitrogenous bases, and Appropriate free nucleotides are added to the complementary DNA strands. DNA coils up.
What is DNA replication?DNA replication is the process through which cells make copies of the genome's DNA. A cell must first copy (or duplicate) its entire genome before it can divide, ensuring that each daughter cell has a complete genome upon division.
One of DNA's most astounding tricks is likely DNA replication. If you stop to think about it, every cell has all the DNA required to create every other cell.
Therefore, DNA is a molecule that can be copied to create almost exact duplicates of itself. Considering that there are almost three billion base pairs in DNA that need to be copied, this is even more astounding. DNA polymerases, which are molecules dedicated solely to copying DNA, are also used in replication.
Therefore, The correct order of replication are DNA unwinds then the The hydrogen bonds are broken between the nitrogenous bases, and Appropriate free nucleotides are added to the complementary DNA strands. DNA coils up.

Explanation:
Scientists reported that a fungal pathogen, may negatively a!ect the growth of soybeans (Glycine max). Soybean growth decreased during three years of high rainfall, and the soybean roots were poorly developed. Close relatives of R. anaerobis are plant pathogens and grow in the soil. A lectin-like protein was found in the soil around the soybean roots. is protein may have been secreted by the fungus. Lectins induce mitosis in some root apical meristem tissues. In many instances, rapid cell divisions weaken plant tissues.You have been asked to investigate whether the fungal pathogen lectin a!ects the number of cells undergoing mitosis in a di!erent plant, using root tips.• What is your experimental hypothesis? Your null hypothesis? Are these the same?• How would you design an experiment with onion bulbs to test whether lectinsincrease the number of cells in mitosis?• What would you measure, and how would you measure it?• What would be an appropriate control for your experiment?Your teacher will provide you with untreated and lectin-exposed roots. You should be comfortable identifying cells in mitosis or in interphase before you begin examining the chromosome squashes.
Answer:
What is your experimental hypothesis?
Experimental hypothesis: If we introduce lectins into the root systems of plants, then they will cause rapid cell division, mitosis, to begin in the root apical meristem tissues which will weaken plant tissues.
Your null hypothesis?
Null hypothesis: If we introduce lectins into the root systems of plants, then there will be no initiation of mitosis in the root apical meristem tissues and the plants will not weaken as a result.
Are these the same?
These are not the same, the experimental hypothesis states that lectin will have an effect on the rate of cell division within the plants which will cause the plant to be weaker, however, the null hypothesis states that lectin will have no effect on the rate of cell division and therefore will not affect the plants overall strength. The null hypothesis is the opposite of the experimental and we are testing the experimental hypothesis to decide whether to accept or reject the null hypothesis.
How would you design an experiment with onion bulbs to test whether lectins increase the number of cells in mitosis?
Assuming these onion bulbs have roots, we would get multiple untreated onions and isolate them by putting them into a controlled environment within a lab by using soil obtained from a store, steady LED light from the room, watered 2 times a day with 2 cups (480 ml) each time and finally isolated the same lab room. The only testable variable in this experiment will be whether the onions are given the lectin or not. In one group we would have the control group, the water they are given would be purely distilled water, however, in another group we would have the experimental group, which would be treated with water mixed with lectin. We are looking to study if there is a change, more specifically an increase, in the cell division of the onion within the treatment/experimental group.
What would you measure, and how would you measure it?
We would need to observe pictures taken of the onion cells under a microscope in order to count the cells in each phase of mitosis. If more cells are visibly undergoing mitosis, and more are present in the picture (density), then we can know that the lectin is causing an increase in rapid cell division. We will compare the amount of cells in each phase with that of the onion which was used as a control.
What would be an appropriate control for your experiment?
An untreated onion that is given distilled water as a treatment, a placebo, which allows us to compare no treatment to the effects of the treatment in the experimental group.
Explanation: I hope the answers are very thorough :) you're welcome future AP Bio students.
If the experiment goes fine, the roots of Group-1 will more denser than the control group.
Experimental hypothesis:
If we introduce lectins into the root systems of plants, then it will increase , mitosis, which will weaken the plant tissues.
Null hypothesis:
If lectins is introduced into the root of plants, then there is no initiation of mitosis in the root apical meristem and the plants will not weaken.
Experimental hypothesis and Null hypothesis are not the same because both statements are opposite.
The onion bulbs with roots, will be divided into 2 groups
1. Onion bulb's liquid media with lectin.
2.Onion bulb's in water only.
The onion bulbs with water apparatus will use as control. The density of the cell will be measured under the microscope.
Therefore, if the experiment goes fine, the roots of Group-1 will more denser than the control group.

In the experiment determining the parental genotype of plant seedlings from a monohybrid cross, if the dominant color was green (C) and the recessive color was white (c), what would the parental genotype have been if plate 1 only contained white seedlings instead of all green
Answer:
cc × cc
Explanation:
This question involves a single gene coding for plant seedling. The green allele (C) is dominant over the white allele (c). This means that the green allele will mask the phenotypic expression of the white allele in a heterozygous state (Cc).
In this experiment where plate 1 only contained white seedlings instead of all green, this illustrates that all the offsprings were recessive. This is because the parental genotypes were both recessive for the color trait i.e. cc.
Note that, the recessive trait can only be expressed when the recessive alleles are present in a gene. Therefore, the parental genotype would have been cc × cc, in order to give rise to all offsprings with the recessive trait (white colour).

Why could organisms that use a K-selected life strategy be more at risk when environmental conditions change?
Answer:
K-selection organisms have the maximum chance of surviving in the surrounding where the number of organisms is near the carrying capacity, however, the lack of offspring makes them endangered species.
Explanation:
K-species can give the offspring with the great possibility of surviving until mature.
K-selection is the most frequent in big animals, that have a long life span, and many generations that meet. K-selection organisms give less offspring but with a stronger organism.
However, these organisms are more endangered, as they tend to have fewer offspring, so their populations cannot recover as quickly from disorders such as excessive hunting or fire.

When a bee visits a flower for sweet, sweet nectar, the plant's gametes are also spread to anoher plant. What kind of symbiotic relationship is this?
Answer:
Mutualism
Explanation:
Mutualism is a type of symbiotic relationship in which the two species of organisms involved benefit from one another i.e. the actions of one benefits the other.
In this question, a bee is said to visit a flower for sweet nectar, however, in the process of feeding on the flowers nectar, the plant's gametes are also spread to another plant by the bee. This is a type of MUTUALISTIC RELATIONSHIP because the plant is beneficial to the bee by providing food (nectar) while the bee also helps the plant by helping it pollinate.

Conjecture what would happen if a primate infant did not possess your chosen primate hand features. Answer this question with the survivability of the infant in mind
Answer:
Where the primate infant did not possess primate hand features, it will not be able to feed itself. For example, a monkey cannot survive without its grasping hands. It uses them to feed itself. So if an infant monkey does not possess the primate hand features, its survival will be greatly hampered.
Explanation:
Ordinarily, primates (including humans) have five fingers on each of their hands and five toes on their feet. Most primate species have fingernails instead of claws, and they have touch-sensitive pads on each of their digits. The hands and feet of all primates are designed for grasping, with the only exceptions being humans. Human beings feature deep perceptions that differentiate them from other primates.
Non-steroidal anti-inflammatory drugs (NSAIDS) block the actions of the COX enzymes and their production of eicosanoids from ___.
Answer:
Arachidonic acids
Explanation:
Non-steroidal anti-inflammatory drugs (NSAIDs) are drugs used due to their analgesic, anti-inflammatory effects.
It inhibit cyclooxygenase (COX) enzyme that takes part in the biosynthesis of prostaglandins (PGs) and thromboxane (TX) and the production of eicosanoids.
Eicosanoids are made by the enzymatic or non-enzymatic oxidation of arachidonic acid or from other polyunsaturated fatty acids (PUFAs) that are close to arachidonic acid which are 20 carbon units in length.
They are important cell signaling molecules that inhibit inflammation, allergy, fever,regulate abortion of pregnancy and normal childbirth, regulating cell growth.

Can I pls get help !!
Answer:
I am not certain but I think it's DNA to RNA to protein may be wrong but I think that's the answer
Answer:
C. DNA to RNA to protein
Explanation:
This question is asking about protein synthesis. Let’s analyze the process.
It begins in the nucleus. DNA is too large to pass through the nucleus, so something has to be done. DNA is “unzipped” using an enzyme called polymerase. Nucleotides attach to create a new strand of messenger RNA, in the process of transcription. The mRNA is small enough to pass through the nucleus.
So the first step is DNA to RNA.
Then, the mRNA makes it way to the ribosome. Here, translation takes place. Transfer RNA reads the mRNA and matches a set of three bases (codon) to an anticodon. The tRNA attaches amino acids based on the codon. A protein will form and bend into a specific shape.
So, the next step is RNA to protein.
Overall, the process is DNA to RNA to protein. Choice C is correct.
