Answer:

The reactions of glycolysis that are shared with those in gluconeogenesis (ie use the same enzymes) are those that Are regulated steps.

Explanation:

Glycolisis and gluconeogenesis are two mechanisms related to the carbohydrates metabolism.  Sometimes they are considered reverse processes. However, they are different because of the control points they have where reactions are irreversible.

Glycolisis and gluconeogenesis share 7 common reactions, that are reversible. Thses reactions are coordinated and regulated by F-2 and 6-BP as the answer to the hormonal action.

Glycolisis happens in the muscle, while Gluconeogenesis happens in the liver. Together they form the "Cori Cycle".

6. Does the insect have a small body with large fan –shaped wings?

a. Yes…………………………………………………………………………… Order Lepidoptera

b. No………………………………………………………………………………Order Hymenoptera

Answer:  

ORDER ODONATA

Explanation:

It is simple to read a dichotomous key. You only need to understand the technical terminology and to detailed observe your specimen. The key will lead you to the answer.

1. Does the insect have wings?

a. Yes………………………………………………………………………… go to step 2

b. No…………………………………………………………………………. Order Hemiptera

We only need to answer this question by looking at the image. In our example, yes, the insect has wings. So we need to go to question number two. Note: In the hypothetical case that the insect would not have wings, it would belong to the Hemiptera order.

2. Does the insect have parallel wings? (hint: Parallel wings don’t stick out to the side)

a. Yes……………………………………………………………………………… go to step 3

b. No………………………………………………………………………………. go to step 4

Ok, here it tells you that parallel wings do not stick out to the side. But in our example, wings do stick out, so the answer should be NO. This species does not have parallel wings. As it is a NO, we go to question number 4.

Note: In the hypothetical case that the insect would have parallel wings, we should read number 3.

4. Does the insect have 4 total wings?

a. Yes………………………………………………………………………………… go to step 5

b. No………………………………………………………………………………… Order Diptera

This one is easy. How many wings our specimen has? Four. Then it is a YES, and we go to question number 5. Note: In the hypothetical case that the insect would not have 4 wings, it would belong to the Diptera group.

5. Does the insect have long antennae?

a. Yes………………………………………………………………………………go to step 6

b. No……………………………………………………………………………… Order Odonata

Our insect has very short antennae. They are not long at all. So, the answer is NO, the insect does not have long antennae. This answer leads us directly to the order of our individual. ORDER ODONATA. Note: In the hypothetical case that the insect would have long antennae, we should read question number 6. And so on until we would reach the order.  

ORDER ODONATA:

Dragonflies belong to this group. These insects characterize as having big eyes, and the separation between them depends on the species. They have an elongated abdomen, sometimes even longer than the wings. Their bodies must be robust to support the massive musculature that propels the wings during flight. The wings are long, big, and wide.

Usually, the males are much more colored than the females are.

Which of the following is the reason in how the anterior pituitary differs from the
posterior pituitary?
O A) the hypothalamus controls the release of posterior pituitary hormones but not the anterior
pituitary
B) the anterior pituitary makes its own hormones; the posterior pituitary releases hypothalamic
hormones
C) the posterior pituitary works independently of the hypothalamus
D) the anterior stores hormones produced by the posterior pituitary

Answers

Answer:

B) the anterior pituitary makes its own hormones; the posterior pituitary releases hypothalamic hormones

Explanation:

The pituitary gland is referred to as "master gland" because it coordinates the activities of other endocrine glands. The pituitary gland is composed of two lobes namely: anterior pituitary and posterior pituitary. These two lobes are individually controlled to release several hormones by the HYPOTHALAMUS.

However, one major difference between the anterior and posterior pituitary lobe is that; the posterior pituitary DOES NOT MAKE ITS OWN hormone, hence, releases the hormones (oxytocin and ADH) it stores but produced by the HYPOTHALAMUS. On the other hand, the anterior pituitary PRODUCES ITS OWN hormones but waits for hypothalamic signal to release them.

what happens to a animal cell placed in a hypotonic solution​

Answers

Answer:

If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). ... A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.

Explanation:

Hypotonic solution is a solution which, contains lesser solute concentration. If animal and plant cells are kept in a hypotonic solution then endosmosis will occur. Endosmosis is a process in which the water molecules move from outside of the cell of lower solute concentration to the inside of the cell of higher solute concentration through the cell membrane or cell wall. Due to endosmosis, both animal and plant cells will swell.

Farmers need to make many decisions about how they grow their crops. One of these decisions is whether to use synthetic fertilizer or organic fertilizer, such as manure.
An advantage of using synthetic fertilizer instead of organic fertilizer is that
A synthetic fertilizer can provide more targeted macronutrients to the crops
B) synthetic fertilizer remains in the soil longer than organic fertilizer does, reducing the volume needed and, therefore, the cost to the farmer
c) synthetic fertilizer adds to soil texture and increases the soil's water-holding capacity
organic fertilizer runs off more readily into waterways, leading to nutrient overload

Answers

C that is what I put and I got it right

An advantage of using synthetic fertilizer instead of organic fertilizer is that

synthetic fertilizer can provide more targeted macro nutrients to the crops.

Synthetic fertilizers are used by farmers to increase crop yield. The fertilizer

are specially formulated to ensure all the macro-nutrients are present in the

right proportions for optimal yield of the crops.

This is the advantage synthetic fertilizers have as organic fertilizer don't

In some areas, human activity is high for burning fossil fuels so these areas create more carbon dioxide.

What are the causes of CO₂ levels?

Growing concentrations as a result of human activities including burning fossil fuels in vehicles and power plants, and industrial operations.

Destroying forests for development or cultivation may increase carbon dioxide levels because plants consume CO₂ in photosynthesis and during respiration CO₂ released into the atmosphere.

Plants absorb more carbon dioxide via photosynthesis than they emit through respiration throughout the day or in the spring and summer, the amount of carbon dioxide in the air decreases.

Therefore human activities produce more CO₂  by burning fossil fuels some area level is high than others.

All organisms must regulate by turning genes on and off in different cells at different times.

a. True
b. False

Answers

Answer:

a. True

Explanation:

The genome can be defined as the complete set of genetic information of an organism which is responsible to produce all the biological components required to carry out its metabolic functions (i.e., development, growth, reproduction, etc). These genes are transcriptionally expressed to produce mRNAs which are subsequently used to synthesize specific proteins (i.e., enzymes and structural proteins) by the process of translation. All organisms (i.e., either unicellular or multicellular organisms) exhibit specific gene expression programs by which such genes are regulated over time. Within the cell, gene regulation is essential to carry out biological processes ranging from development and differentiation to cell cycle arrest. These gene expression programs are acutely regulated via genetic (e.g., transcription factor binding) and epigenetic (e.g., DNA methylation) mechanisms, which work together in order to turn on/off genes during development.

A random mutation occurs and the GGA codon is changed to CGA, what effect does the substation have on amino acid

Answers

Answer:

The replacement of a base at a codon, as occurs when the GGA codon is changed to CGA, causes a change in the amino acid glycine to arginine.

Explanation:

Nitrogen base changes in a codon usually result from base changes in the DNA before transcription into mRNA,called point gene mutations.

In the case presented, the substitution of the guanine base by cytosine in the GGA codon--resulting in a CGA codon--generates a change in the coding amino acid resulting in arginine instead of glycine.

The change of an amino acid in a peptide or protein can mean an alteration in the structure or function of these molecules.

Because an amino acid can be encoded by several codons, changes of a nitrogen base at a codon sometimes do not involve changes in the amino acid sequence of a protein.

Answers

This kind of genetic engineering can be pursued, but with caution. Making an animal more resistant to common infections can reduce the need to administer antibiotics, which often ends up in the milk and meat, and can also save money for the farmer. It can result in healthier farm animals that produce more milk and meat. However, in some cases genetic engineering can produce sicklier and weaker offspring than wild type, sometimes as an unforeseen effect of the phenotype, but sometimes as an effect of a weaker DNA molecule that breaks easier. Some consequences of this include reduced fertility and offspring viability. For society, it could be seen as a benefit if it ups the production of milk and meat because it could drive down the cost, since more goods are being produced per farm animal than before. In terms of the environment, it might be beneficial because the antibiotics that would have otherwise been passed through the animal and ended up in animal waste, where it could effect the local ecosystem in a negative way, do not end up doing that since the animal itself is no longer in need of large doses of antibiotics.

(Beautiful Mind) There is an interesting scene in A Beautiful Mind in which John Nash's character discovers his equilibrium concept. The setup is that there are four men and five women at a bar, and each man must simultaneously walk over to a woman. One of the women, who is blonde, is considered to be more desirable than the other four, who are all brunettes. Although the men all prefer the blonde to the brunettes, if they all go for the blonde they will "block each other" (according to the logic of the movie) and end up unsuccessful; moreover, after going for the blonde, they cannot then go to a brunette because the brunette would be offended at being someone's second choice and would turn down the man. Nash's character then realizes that what ought to happen is for each of the four men to choose a brunette. Let's try to put this situation in a game theoretic model by using a to denote the payoff a man would receive if another man goes for the same woman he does (here there are assumptions that it is possible to "block each other" on brunettes and that being "blocked" on a brunette gives the same payoff as being "blocked" on a blonde, although this is not important for the problem). We'll use b to refer to a man's payoff if he is the only man to go for a woman and that woman is a brunette. We'll use c to refer to a man's payoff if he is the only man to go for a woman and that woman is blonde. The natural restrictions on payoffs are a < b < c. Is there a pure strategy Nash equilibrium where each man ends up with a brunette? What are the pure strategy Nash equilbria? How do these answers change if the blonde turns down everyone (meaning that the payoff to going to the blonde is a, regardless of how many men choose her)?
