Answer:
4 gametes
The cells that enter meiosis II are the ones made in meiosis I. These cells are haploid—have just one chromosome from each homologue pair—but their chromosomes still consist of two sister chromatids. In meiosis II, the sister chromatids separate, making haploid cells with non-duplicated chromosomes.

Does anybody know what a Non-environmental factor that triggers mutation? Give me one example
Answer:
A mutation can occur when mistakes are made during DNA replication.
Explanation:
Numerous factors may result in mutations. Some mutations appear to occur on their own, without any environmental factor. They can happen when transcription or replication errors are created in DNA.
What is mutation?The alteration or modification of a person's nucleic acid or DNA sequence is known as a mutation.
This is a normal process that happens because mutagens lead to mutation. Additionally, for certain objectives, man-made mutations can be created to change the gene sequences.
There are many different kinds of mutations, including chromosomal mutations that change the structure of chromosomes and somatic mutations that impact body cells.
Therefore, mutagens, which may be both environmental and non-environmental, can trigger the mutation in DNA.

Summarize the process of cellular respiration in your own words. Consider where you get the initial glucose from and all of the outputs when making your summary.
The cellular respiration process is as follows:
Glucose is the main sugar that circulates in the blood and is the first source of energy in the body for living beings that comes from the food we eat.Through the oxidation of glucose, various compounds are produced that provide energy, the body absorbs sugar from food and transforms it into energy thanks to metabolic activity.Said metabolic reactions is known as cellular respiration that take place inside the cells of living beings, through which chemical energy is obtained from the decomposition of organic molecules.The process of cellular respiration consumes glucose as fuel and oxygen as final electron receptor (oxidant) in reaction with pyruvic acid.Thus, carbon dioxide (CO2), water (H2O) and numerous amounts of ATP, the molecule of biochemical energy, are obtained.Therefore, we can conclude that cellular respiration involves a metabolic process by which glucose is initially oxidized and energy and water are produced.

What makes up the highest percentage of soil composition?
A.) Mineral matter
B.) Water
C.) Air
D.) Organic matter
Answer:
D
Explanation:
^
The one that makes up the highest percentage of soil composition is mineral matter. The correct option is A.
What is soil composition?In soil science, a soil type is a taxonomic unit. A distinct soil type is formed by all soils that share a specific set of well-defined properties.
Soil type is a technical term for soil classification, which is the science of systematic categorization of soils. Every soil on the planet belongs to a specific soil type.
The composition of the soil is an important aspect of nutrient management. Soil water is what readily provides nutrients for plant uptake, whereas soil minerals and organic matter hold and store nutrients.
A typical soil contains about 45% mineral matter, 5% organic matter, 20-30% water, and 20-30% air. These percentages are, at best, broad strokes.
Thus, the correct option is A.

Rey, who has a normal vision (XY),married Cindy
who has a normal vision but carries a gene for
color-blindness (XX) What is the chance to
have a colorblind baby girl?
Answer:
There is no chance that Rey —who has a normal vision man— and Cindy, who is a woman colorblind carrier, will have a colorblind daughter.
Explanation:
If a man with normal vision and women who is a carrier of colorblindness has a daughter there is a 50/50 chance of having a colorblindness carrier daughter. And all daughters would have normal vision.
Color blindness is a visual condition characterized by the inability to discern some colors, and has a recessive inheritance pattern linked to the X sex chromosome. This means that all males with the defective gene (Xd) would be color blind, while a female to be color blind must have both X chromosomes affected.
In the case of Rey and Cindy
♂ XY
♀XdX
Alleles X Y
Xd XdX XdY
X XX XY
Of the daughters they have, half could be carriers, while the other half would not have the altered gene. In any case, none of their daughters could be colorblind.

Why do we say chloroplasts look like green footballs even though a lot of the time they look like perfect green spheres?
Answer:
Explanation:
The football used in American Football is an oval. Chloroplasts can be spherical but also oval-shaped. For the rest of the world, football is what people in the U.S. call soccer. So a football can also be spherical in shape and thus chloroplasts can be spherical just like footballs are. Chloroplasts can also be disc-shaped.

is Fat around organs
structure of cell membranes
protection
chemical messenger
Answer:
protection
Explanation:
The "fat" around the organs is called the "visceral adipose tissue." Its primary function is to "protect" the organs it encloses from injury. It also keeps the person warm especially when exposed to cold environments. Besides this, it also serves as a storage area for your calories in the body. Fat is not completely harmful as most people think.
This is the reason why it is not good to lose so much weight or become too skinny because losing some fat may be harmful to your organ's protection and heat regulation.

As many as 30 thousand ____ _______ become entangled in lost or discarded fishing nets or cargo straps each year.
Answer:
As many as 30 thousand fur seals become entangled in lost or discarded fishing nets or cargo straps each year.
Explanation:
Human activities cause many damages to marine mammals in general. One of these activities is fishery. The nests are intercepting the migratory routes of animals or are floating free in the sea after being discarded. They are extremely strong, so whenever animals get stuck on them, they might carry them for months or years, affecting their diving, foraging, feeding, and reproductive behavior. These nets might hurt the animals´ skin, producing a wound that will probably get infected.
A few years ago, at least 50,000 northern fur seals died per year after getting stuck in fishing nets. The populations of these animals decreased sharply, affecting their reproductive and growth rates. In the present, due to the decrease in their population size, the number of dead animals is around 30,000 per year. This reduction in death is only because there are much fewer animals every year.

What are two ways to increase the energy of a wave?
•Increase the wavelength and increase the frequency
Increase the amplitude and increase the frequency
Decrease the amplitude and increase the wavelength
Increase the speed and decrease the frequency
The two ways to increase the energy of a wave are increase the amplitude and increase the frequency. The correct option is B.
What is a wave?A wave is a propagating dynamic disturbance of one or more quantities in physics, mathematics, and related fields.
Periodic waves occur when quantities oscillate repeatedly about an equilibrium value at some frequency.
The amplitude and frequency of a wave are related in such a way that they are inversely proportional. With increasing frequency, the amplitude decreases. As the frequency decreases, the amplitude increases.
The amount of energy in a wave is determined by its height, wavelength, and the distance over which it breaks.
When equal wavelengths are used, a wave with a larger amplitude will release more energy when it returns to sea level than a wave with a smaller amplitude.
Thus, the correct option is B.
