In what phase of meiosis are sister chromatids separated and pulled to opposite ends of the cell? A. Anaphase IB. Anaphase II

C. Metaphase II

D. Metaphase

Answers

Answer 1
Answer:

Answer: B ,  Anaphase ii

In Anaphase ii of meiosis, the sister chromatids are separated and pulled to opposite ends of the cell. After metaphase ii, the centromeres(to which spindle fibres are attached) separate, and the two chromatids of each chromosome move to opposite poles on the spindle. The separated chromatids are now called chromosomes in their own right.
Answer 2
Answer:

The correct answer would be...

Anaphase II

Compare and contrast carbohydrates and proteins.Describe the function of each macromolecule.
Explain one way they are the same and one way they are different.

Answers

Carbohydrates and proteins are two types of macromolecules that play critical roles in living organisms.

How carbohydrates are made?

Carbohydrates are organic molecules made up of carbon, hydrogen, and oxygen atoms. They are primarily used as a source of energy for the body, but they also serve other functions such as structural support, cell signaling, and cell recognition. Some examples of carbohydrates include sugars, starches, and fibers.

Proteins, on the other hand, are organic molecules made up of amino acids. They have a wide range of functions, including structural support, enzyme catalysis, transport, storage, communication, and defense.

One way that carbohydrates and proteins are similar is that they are both macromolecules that are essential to life. They are both made up of smaller building blocks - monomers - that are linked together through chemical bonds to form more complex structures.

One way that carbohydrates and proteins are different is that their functions are distinct. While carbohydrates are primarily used as a source of energy, proteins have a wide range of functions that are critical to the structure and function of the body.

In summary, carbohydrates and proteins are both important macromolecules with distinct functions. Carbohydrates are primarily used as a source of energy, while proteins have a wide range of functions critical to the structure and function of the body. While they share similarities as macromolecules, their functions are distinct and serve different purposes in the body.

Answer:

1.Carbohydrates are used for energy (glucose). Fats are used for energy after they are broken into fatty acids. Protein can also be used for energy, but the first job is to help with making hormones, muscle, and other proteins. Broken down into glucose, used to supply energy to cells.

2.Nucleic acids: Stores and transfers info. Carbohydrates; Store energy, provide fuel, and build structure in body, main source of energy, structure of plant cell wall. Lipid: Insulator and stores fat and energy. Protein: Provide structural support,transport, enzymes, movement, defense.

Cooking an egg uses heat to rearrange the atoms in the proteins of the egg. This is an example of an:Group of answer choices

Endothermic reaction

Exothermic reaction

Answers

Endothermic reaction

An endothermic reaction is those reactions  that take up energy from the environment as that proceeds. The opposite is an exothermic reaction that gives off energy to the environment.

Explanation:

When cooking an egg you require energy to break down the interactions between the protein chains and atoms of the raw egg so they are rearranged into a cooked egg. This is akin to the denaturing of proteins. Cooking food helps ease their digestion. Because we need energy to break down the interactions and bonds of the proteins in the egg this is why we use fire in cooking. This is, therefore, an endothermic reaction.

Viruses A. usually infect only specific types of cells. B. reproduce on their own and sometimes within hosts. C. are nonliving particles. D. are able to crystallize.

Answers

The answer is letter B.

Viruses have the ability to reproduce on their own andsometimes within hosts. It is an infectious agent that can affect all types oflife forms (e.g. animals, plants, microorganisms). They are found in almostevery ecosystem on Earth and they are the most abundant type of biologicalidentity.  Asvirology is the study ofviruses which is a sub-specialty of microbiology. The spread in many ways andcan be transmitted from one organism to another or sometimes to multipleorganisms at the same time. Its origins in the evolutionary history of life isstill unclear but they are considered to be life forms because of theircapacity to carry genetic material, reproduce, and evolve through naturalselection.

For a given species an increased evolutionary rate would cause a decrease in

Answers

For a given species an increased evolutionary rate would cause a decrease in mutation rate.
>Three factors that would increase the rate of evolution would be the intensity of directional selection, an increase in the birth rate, hence an increase in the number of possible beneficial mutations, and an increase in the population size.>There are many limiting factors that might control the evolutionary rate of change. Physical or biological changes influencing the environment can play a major role in the rate of evolutionary change.
