Answer:

I think option B and C is correct answer

Mendel used pea plants as they were easy to grow and exhibit several distinct traits that vary.

Mendel's Experiment

Mendel's experiment was accomplished with the help of Pisum sativum, that is, the garden pea to study inheritance.

Mendel chose pea plants as they are easy to grow.

They also possess many visible features, which may vary.

These features comprise seed color, seed form, flower color, pod color and form, placement of flowers and pods on the stems, and length of the stem. Each of the feature has two common values.

Thus, the correct answers are options C and D.

where does pyruvate as intermediate take place in photosynthesis? plz explain also thanks

Answers

Answer:

Pyruvate take place after the process of glycolysis.

Explanation:

Pyruvate as intermediate take place in the process of photosynthesis after glycolysis process. One glucose molecule is converted into two molecules of pyruvate. This pyruvate molecule then converted into acetyl CoA, which is a two-carbon molecule. A molecule of coenzyme A is a very important reactant for this reaction, which produces a molecule of carbon dioxide and reduces a NAD+ to NADH.

Answers

Answer:

B. What happens to the materials that make up a living organism after it dies.

Explanation:

An ecosystem can be defined as the natural living habitats of both living and non-living organisms.

Ecosystem services such as plant pollination, nutrient cycling and water purification are essential services that are being provided by the ecosystem. These services are really very vital, important and useful for the sustenance of life, both for humans, plants and animals because they enhance social welfare.

In this scenario, Haley knows that plants and animals are made up of many different materials. She wants to know how these materials can cycle through an ecosystem. Therefore, the question Haley could ask to learn more about this topic is; what happens to the materials that make up a living organism after it dies?

Basically, the material that make up a living organism decomposes after it dies and are then used up as nutrients by plants growing on the soil.

cells so they may facilitate the exchange of substances are

Answers

Answer:

Capillaries

Explanation:

Capillaries are one of the three major blood vessels in humans (the other two being; veins and arteries). They are known to connect the arteries and the veins together in the circulatory system. Capillaries majorly function in the exchange of substances e.g oxygen, nutrients between the blood and tissues.

Due to their role in exchanging substances via diffusion, capillaries contain the simple squamous type of epithelial tissue, which helps them perform this function. Furthermore, capillaries are the smallest in diameter and most abundant in number of all blood vessels.

Answers

Answer:

Vary in height primarily because of the degree of various stressors on each population

Explanation:

Shorter plants became taller because of the various stressors such as unavailability of sunlight. Due to unavailability of sunlight, the plants grow taller for gaining solar radiation that is required for the process of photosynthesis. So we can say that the environmental condition or stress brought changes in the plant body.

igneous rock determined 25 million year old plate movement transported 100,000 meters. How fast is plate moving?

Answers

Answer:

0.004 m/yr.

Explanation:

Hello!

In this case, since the velocity of any object is computed by dividing the travelled distance by the elapsed time, we obtain:

[tex]V=\frac{distance}{time}\\\\V=\frac{100,000m}{25,000,000yr}\\\\V=0.004m/yr[/tex]

It means that the plate moves 0.004 m every year.

e) Both animals use their upper limbs for the same function

Answers

The answer is a, both animals have tails as embryos.

Both chicken and the cat begin with a tail, though eventually for the chick, it looses its long tail. Unlike the cat it keeps the tail it had when it was a fetus. That’s a shared characteristic embryo until they are fully developed.

1. Discuss how the study of fossils provides strong evidence for evolution. (13.2 and 13.3)

Answers

Answer:

in fossils we see homologous structures that suggest a common ancestor.

By looking at the bones of the arms and comparative anatomy we see the similar structure and function that is retained.

When looking at other animals like birds we see Analogous structures that look similar but have a different function (flying).

Finally we see Vestigial structures which are structure that no longer function as they once were used for. An example of this is the coccyx (tail bone in humans) compared to tails in dogs, cats, monkeys, etc.

Answers

Answer:

b. Pasteurized milk stored at room temperature for 4 days

a. Pasteurized milk stored at 4*C for one week

c. Autoclaved milk

Explanation:

Autoclaved milk has least expected bacterial growth because Autoclaved sterilization kills all the bacteria present in it so little chance of bacterial growth. Pasteurized milk stored at room temperature for 4 days has more bacterial growth due to favorable environment whereas little growth occur in the Pasteurized milk which stored at 4*C for one week due to less favorable environment.
