A scientist is comparing the sequences of related genes among three species. Two of the species have very similar sequences, while the sequence of the third species differs greatly from the others. T

Answers

Hi. The question you presented above is incomplete. This makes it impossible for this question to be answered. However, when searching for your question on the internet, I was able to find another question exactly like yours, which asked you to explain the evolutionary relationship between these three species. If that's the case for you, I hope the answer below will help you.

In a simplified way, we can infer that among the three species presented above, the third presented a faster evolution than the first two and this is what explains the difference between the gene sequences between the species. As the question presents, the three species have related genes, which indicates that they had a common ancestor, however the difference in the gene sequence of the third species shows that it evolved first, showing changes that cannot be noticed in the first two species that are evolving more slowly.

qué ventajas le trajo al ser humano el poder andar en 2 patas.

Answers

Answer:

The advantage that hominids had when they developed bipedalism is truly great. Walking on two legs instead of four allowed hominids to free up their arms. Using their arms they could now make tools, stretch trees, and use their hands for social communication. The development of bipedalism also allowed for long-distance walking and eventually endurance running. Bipedalism, basically, was a key step for hominids' "brains to grow".

[tex]{\sf{\boxed{\boxed{\tt\green{Las \: ventajas}}}}}[/tex]

La gran cantidad de ventajas que trajo el bipedalismo significó que todas las futuras especies de homínidos llevarían este rasgo. El bipedalismo permitió a los homínidos liberar completamente sus brazos, lo que les permitió hacer

English:

The advantages

The host of advantages bipedalism brought meant that all future hominid species would carry this trait. Bipedalism allowed hominids to free their arms completely, enabling them to make and use tools efficiently, stretch for fruit in trees and use their hands for social display and communication.

Rocky shore and sandy shore similarities

Answers

Rocky shores, like beaches (or sandy shores) are characterized by the life that lives in the intertidal zone – the area between the high tide and low tide water levels. Life on rocky shores is tough. It is dominated by the need to deal with very high wave energy, regular exposure to the air/sun, and interactions between these two physical stressors and the strong biological pressure applied by voracious intertidal predators.

How is oxygen carried from your lungs into all of your cells for cellular respiration?

1. It slowly diffuses throughout your whole body from your lungs
2. It is carried by your red blood cells through your blood stream
3. Cellular respiration only takes place in the lungs, so you do not need to transport oxygen
4. Oxygen is not necessary for cellular respiration

Answers

Answer:

2.  It is carried by your red blood cells through your blood stream.

Explanation:

The oxygen in inhaled air passes across the thin lining of the air sacs and into the blood vessels. This is known as diffusion. The oxygen in the blood is then carried around the body in the bloodstream, reaching every cell.

A scientist studied a population of birds for 10 years. During that time, the population was never fewer than 30 birds and never more than 50. Her data showed that over half of the birds born did not survive to reproduce, because of competition for food and predation. She noticed that In a single generation, about 90% of the birds that were born lived to reproduce, and the population increased to 90. Which inference(s) about this population might be true

Answers

Answer:

A particular population limiting factor or factors must have been removed

Explanation:

The population of the birds must have been kept between 30 and 50 individuals by population limiting factors such as the presence of predators within the community or competition for resources such as food or spaces.

For the population to shoot up to 90 all of a sudden, it may be that one or more of the population limiting factors has been removed from the population. It could be that a major predator has been removed from the community or the competition for food/space is now significantly reduced due to more food/space in the community.

how can we apply the principle of transpiration in producing clean water?​

Answers

Explanation:

Transpiration is a process that involves loss of water vapour through the stomata of plants. The loss of water vapour from the plant cools the plant down when the weather is very hot, and water from the stem and roots moves upwards or is 'pulled' into the leaves.

Answer:

During photosynthesis, the layer of TiO2 absorbs light, breaking down toxic pollutants in the water, while the gold layer emulates the transpiration of a leaf and harnesses sunlight to evaporate the water at the surface. The resulting vapor condenses into completely-purified water.

Answers

Hello. Unfortunately your question is incomplete, which makes it impossible for it to be answered. However, through the context, we can see that your question is asking you to describe the cellular structures that you can see through a microscope.

To answer this question, you will need to look at biological material under a microscope to see what cells this material has and the structures it has. To do this, you will need to determine what material you will be using. This material can be a leaf, flower, a piece of fruit, or any other material that contains cells. After choosing the material, you need to search for a protocol, a tutorial, that shows how this material can be prepared so that the cells can be visualized through a microscope. This protocol can be found on the internet and in articles. You must follow the entire protocol to the letter, to be able to identify the cellular structures.
