Answer:

B. Glucagon

Explanation:

Glucagon is a pancreatic hormone, secreted by the alpha cells of islets of Langerhans. Whenever the blood glucose level falls, glucagon is released to increase the blood glucose levels. This function of glucagon is quite opposite to the function of insulin and hence both are antagonistic hormones. Insulin reduces the blood glucose where as glucagon increases the blood glucose.

Glucoagon is large polypeptide of 29 amino acids. Since it helps in increasing the blood glucose homeostatic levels it is called as hyperglycemic hormone. It does so by stimulating certain processes such as:

- Stimulating Glycogenolysis i.e breakdown of glycogen to release more glucose from liver.  

- Stimulating Gluconeogenesis i.e. synthesis of glucose from non-carbohydrate sources like proteins.

- Glucagon inhibits the process of glycogenesis i.e. synthesis of glycogen, the storage form of glucose.

jarptica [38.1K]

Answer:

Water has properties of cohesion and adhesion.

Explanation:

The single Hydrogen atom and double Oxygen atoms attach to each other in such a way their are minute polar polarity differences.  Electron bonds will combine to form one side of the compound as being positive and the other side positive.  Positive side of other H2O molecules will attach to the negative side.  This bond causes water to adhere to sides of a glass test tube.

Will also create a bead when it drips on another non-porous surface.  Adding soap will break the bead (surfactant).  Water is the perfect solvent.

Name the five cardiac cycle activities starting with excitation and ending with regulation of blood flow and volume.
stira [4]

Answer:

Explanation:

1) Excitation brings about contraction.

2) Contraction leads to an increase in blood pressure.

3) Changes in blood pressure results in the opening and closing of the heart valves.

4) The opening and closing of heart valves then regulates the flow of blood and it's volume.

5. Which of the following statements best explains the role of meiosis in reproduction?
kiruha [24]

Answer:

The correct answer is: Meiosis makes it possible for a zygote to have the correct number of chromosomes.

Explanation:

Meiosis is a type of cell division used by reproducing organisms to produce the gametes (as sperm or egg cells). It has two rounds of division that results in four cells with one copy of each chromosome.

Before the division, genetic material from each chromosome is crossed over and creates new combinations of code on each chromosome. During fertilization, the cells produced by meiosis will conjoin to create a cell with copies of each chromosome again, the zygote.

Hey can someone please help me with these questions. Im having a hard time with them.
Reika [66]

Answer:

See below.

Explanation:

1. C. an increase in clean water sources.

If we think about this in terms of humans, our growing population, this should be the correct answer. Through the creation and usage of carbon emissions (ie. using gas to power cars and the smoke that comes out as exhaust in those cars) decreases are quality quickly. Additionally, this directly relates to an increase of global warming, as the contribution of greenhouse gases ups the temperature on earth. As wood and the materials with it are a large source of material for us, deforestation is common and happens all the time, so that in itself (along with all the other points stated) are direct contributions/ causes of our growing population.

Thus, the answer will be C.

2. B. Burning fossil fuels in power plants.

Dumping waste matter into ocean waters doesn't essentially rise the temperature of the earth, as is defined as global warming. It's bad, yes, but not a direct/ big contributor to it. Using pesticides on agricultural crops, too,  doesn't necessarily affect global warming as much as the other options provided. Now, in clearing native forests with industrialization, that's where it gets tricky. We use machines and whatnot to do this, so you could say that this is a huge factor. However, this isn't the case, as global warming is <em>most </em>affected by the burning of fossil fuels (you know- "warming" and "burning" do kinda correlate for a reason here).

Thus, the answer is B.

3. C. the increased supply of resources.

Graph 2 starts to go up slightly before it skyrockets upward, slowly starting to level out afterward, yes? So, what'll be the cause of this. Obviously if there's something increasing this and the population, a decrease won't be the answer. Additionally, if we're assuming both graph start out with the same amount of resources, then the demand would still be high, right? So our answer cannot be D. Now we're left with options A and C. While A may <em>seem </em>like a correct answer, this scenario depends more on quantity as opposed to quality (it won't matter how good the resources are if you don't have enough of it), so this will leave our answer to then be C.

4. D. for about 3 months.

If we take a look at the graph and where the carrying capacity is finally reached, we'll see this moment in time is on August 1st. Now, if we've initially started documenting this rabbit population on May 1st, we'll understand that there is a three month gap between them, thus providing us with the answer of 3 months.

If this is still a bit confusing as to why it's not 4 months (which may not be a problem for you but it always was when I was younger), you can think of it as this:

May to June is 1 month. June to July is 2 months. July to August is 3 months.

5. F. more access to contraception

Now, a few of these you can cross out quickly. It won't be option B because that would indicate a high jump in growth rate, it won't be option C because that has no direct impact on anything in this scenario, it won't be option D because high education is available in many places (meaning that it wouldn't affect anything in a <em>specifically </em>more developed country), and it won't be option E because that would lead to an increase. Now we're left with options A and F- which one is it?

A higher cost of living would definitely deter people from having kids, but would it lead to a slower growth rate? Not necessarily. People still have kids in harsh times, so that's not necessarily what would be the leading cause. More access to contraception, however, <em>would </em>lead to a slower growth rate. If people have more access to the means of not stopping them from having kids, and then they choose to take this option, then this would be the correct answer.
