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 most 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 seem 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 specifically 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, would 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.

Hemoglobin is a protein found in red blood cells that is comprised of two alpha and two beta subunits that surround an iron-containing heme group. Oxygen readily binds this heme group.

DNA replication is the method by which a double-stranded DNA molecule is replicated to produce two similar DNA molecules.

Copy is an important method because, whenever a cell divides, the two new daughter cells must have the same genetic information, or DNA, as the parent cell.

DNA replication is the method by which the genome's DNA is replicated in cells.

A cell divides, it must first copy its entire genome so that each resulting daughter cell ends up with its own full genome.

Thus, Copy is an important method because, whenever a cell divides, the two new daughter cells must have the same genetic information, or DNA, as the parent cell.

Answer:

Different elements have different half lives, which means that certain elements are only useful for determining the age of a rock up to a certain age.  Carbon-14, for example, is great for dating archeological finds as old as 50,000 years.  But that's the limit of its usefulness.  I would not be useful for dating dinosaur bones.  For that you would need an element with a much longer half life, such as Uranium-238, which has a half life of more than a million years.

Answer:

Yes

Explanation:

The mom has greater features than the dad's side so the child is going to have more of what the mom has. Like black hair is a dominant feature maybe the mom had black hair that dad had red black is the dominant trait.

I totally disagree with this student. This is because, during the successful fertilization, 23 chromosomes of each parent get fused in order to form a total of 46 chromosomes. The amount of DNA from both the parents is equally inherited by the students.

DNA may be defined as a type of molecule that is significantly found inside each cell that contains the genetic information responsible for the development and function of an organism. It stands for deoxyribonucleic acid.

The amount of DNA from both parents is equally inherited by the students. But the main thing behind this concept is that the child shares more similarities with his mother's side of the family due to DNA fingerprinting.

While this mechanism creates variation when it comes to the father's side. And hence it provokes more differentiation with respect to father.

Therefore, it is well described above.

Answer:

The digestive system relies on the circulatory system to deliver the nutrients to the entire body of the organism.

Explanation:

» Concepts

The function of the digestive system is to break down food into nutrients for your body to use as energy. However, once the food is broken down, the nutrients pass onto the bloodstream. Then, the circulatory system takes action and transports them throughout your body.

Answer:

The 3 body systems that both humans and fish have in common are circulatory, respiratory and digestive system.

When we breathe in air, our lungs pull oxygen from it and transmit it into our bloodstream while also producing carbon dioxide. The gills function similarly in the majority of fish, although not all.

Fish consume food through their mouths, then they digest it in their esophagus.

The pyloric caeca, which are finger-shaped pouches that process food in the stomach and secrete digestive enzymes and absorb nutrients, are found in many fish.

Cold-blooded aquatic vertebrates called fish can be found in both freshwater and saltwater.

Similar to humans, they have a closed circulatory system in which a network of blood arteries keeps the blood constantly contained.

Thus, these are the three body systems.

Answer:

The pre-mRNA has to go through some modifications to become a mature mRNA molecule that can leave the nucleus and be translated.

Explanation:

Eukaryotic pre-mRNAs are modified with a 5' methylguanosine cap and a poly-A tail. These structures protect the mature mRNA from degradation and help export it from the nucleus. These include splicing, capping, and addition of a poly-A tail, all of which can potentially be regulated – sped up, slowed down, or altered to result in a different product.

Answer: There are two categories of cross membrane transport, active and passive. While active transport requires energy, passive transport relies on concentration differences inside and outside of the membrane. With films that cover the outermost membrane of the fruit (the skin), this concentration gradient can be removed or slowed so membrane transport is also slowed and as a result, the fruit stays fresh longer. A good analogy for this is considering evaporation in an open jar on a hot day versus if there was a lid on the jar. Both jars would be in the same conditions, but the jar with the lid would retain more water.
