When comparing dogs to wolves, scientists found evidence that supports the idea they come from a common ancestor. Which evidence was most important in understanding this?A comparable anatomies, fossils, and behavior
B different anatomies, similar development, and different DNA
C comparable anatomies, similar development, and similar DNA
D different anatomies, fossils, and behavior

Answers

Answer 1
Answer: Evolution overs over time such that the best traits are being passed on from successive generations in every species or populations. We can compare these different species from a common ancestor. Evidences include fossil evidence, genetic evidence, comparative anatomy and more. These are usually shown in phylogenetic trees. Most apparent differences between wolves and dogs are their anatomy or morphology. Fossils support these. Behavior between them are different especially in terms of mental differences.

Best answer is A.

According to the phylogenetic tree, from which domain did Eukarya evolve?

Answers

According to the phylogenetic tree, the Eukarya, or the Eukaryotic cells, rose around 2 billion years ago, give or take a fer hundred million, from the Archaea domain. The Archaeas are single-celled organisms that belong to the Prokaryotic type, meaning that the Eukarya are more complex since they have a nucleus and build together multi-cellular organisms.

Archaea and Eukarya.

On the basis of the information provided in the question, the ultimate branch of the phylogenetic tree starts with the line of Eukarya and then possesses the species of the Archaea division that comprises those prokaryotic species, which thrives in extremely tough environmental scenarios.  

As the last branch possesses species of two domains, that is, Eukarya and Archaea and it starts with Eukarya and afterward holds the species of Archaea, which shows that both Eukarya and Archaea are associated genetically.  

Why is it important for scientists to develop a way to grow tissues that have a built-in system to supply blood

Answers

  • It is important for the scientists to grow the tissues that have a built in system to supply blood to decreases the chances of organ rejection.
  • There is a very serious issue regarding this the transplanted organ does not gets the vascular blood supply which is the main reason for organ rejection.
  • If there will be tissues with its own blood supply then it will not be ejected by the body.
A lack of blood flow determines the number of cell layers that can
survive when they are transplanted

Give an example of 4 type of movable joint and describe the type of action which the joint permits.

Answers

The 4 types of movable joints are:
1) Hinge joint - a joint that works like a hinge of a door. example: elbow joint

2) gliding joint - this joint allows a bone to slide over another, this joint is found in wrists and ankles.

3) pivot joint - a freely moving joint in which movement is limited to rotation. pivot joint in the neck located at its 1st and 2nd vertebrae. allows the head to move back and forth.

4) ball and socket joint - rounded end of one bone fits the cup like end of another bone. example is the glenohumeral joint in the shoulder.

Explanation:

 now that you know the bacteria in each tank drag the tanks to put them in the correct order

Answers

Answer:

1st ammonia nitrifying

2nd nitrite nitrifying

3rd denitrifying

Explanation:

Final answer:

The task involves arranging tanks according to the bacteria present in them, which could be determined by their type or concentration. Knowledge of different bacteria and their characteristics or quantities may be required.

Explanation:

The question is related to sorting tanks based on the bacteria present in them. This might involve consideration of different bacterial species, or possibly the number or concentration of bacteria in each tank. For example, if one tank has E.coli bacteria, another one has Staphylococcus, and a third one has Salmonella, you would need to arrange the tanks based on certain given criteria, perhaps related to the properties of these specific bacterial species.

On the other hand, if the task is about counting bacteria or organizing based on their concentration, microscopy might be used to estimate the bacteria in a sample from each tank. Given numbers could then be used to arrange the tanks in ascending or descending order.

In cells, the energy available in food is used to make an energy-rich compound calleda.water
b. glucose
c. ATP
d. ADP

Answers

The answer is letter C. ATP.

ATP stands for Adenosine Triphosphate which is present in every cell’s cytoplasm and nucleoplasm which is essential in all the physiological mechanisms. It is considered as the energy currency of life or the “molecular unit of currency”.  It stores the energy that we need every day to do our daily undertakings. The primary function of ATP is to transport chemical energy within the body cells for metabolism. It is said that 1 moleculte of ATP is composed of 3 phosphate groups.
