Answer:

C - gas and dust in a nebula is disturbed by an outside forces.

Explanation:

Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas called solar nebula.

The cloud of interstellar gas and dust consist of 98% hydrogen and helium and it also includes atoms and dust particles of larger materials.

Which carbohydrate is not found in foods from plants?
devlian [24]

Out of the following given choices;

a. fructose

b. glycogen

c. sucrose

d. starch


The answer is; B.

Glycogen is only found in animals, bacteria and some fungi. It is analogous to starch (amylopectin) in plants and is also made up of glucose and sucrose polymers. It is highly branched and compact in structure than starch. Glycogen is used as a storage reserve for excess glucose in animals and is stored mainly in the liver and muscles.

Imagine there are 25 different species of protists living in a tide pool. Some of these speciesreproduce both sexually and asexu
Stels [109]

Answer:

D)the sexually reproducing species

Explanation:

  • Sexual reproduction is a mode of reproduction in which two parents are required to generate an offspring.
  • As this mode of reproduction requires two parents, the genetic composition of the offspring is a mixture of both the parents and hence, sexual reproduction gives rise to genetic variation.
  • Genetic variation is essential to survive in a changing environment as it can lead to the development of certain characters that prove to be essential for survival.
  • Therefore, if there are 25 different species of protists in the tide pool, it is the sexually reproducing species that will be able to thrive in the changing environment as their offsprings will have genetic variation and this may lead to a positive natural selection.

How is the process of photosynthesis taking place thru Calvin Cycle?
Juli2301 [7.4K]

This is the ideal question! Thanks for asking!

Before we start, let's go through a mini-review.

Photosynthesis:

The complex process by which carbon dioxide, water, and certain inorganic salts are converted into carbohydrates by green plants, algae, and certain bacteria, using energy from the sun and chlorophyll.

Calvin Cycle:

A series of biochemical reactions that take place in the stroma of chloroplast in photosynthetic organisms.

Now that we have gone through what these two terms are and their definitions, let's head onto the actual questions.

So the question asks, how is the process of photosynthesis taking place through Calvin Cycle?

In plants, carbon dioxide (CO2CO2CO2​C, O, start subscript, 2, end subscript)  enters the interior of a leaf via pores called stomata and diffuses into the stroma of the chloroplast—the site of the Calvin cycle reactions, where sugar is synthesized. Because they are not primarily fueled by light, these reactions are often known as the "light-independent reactions."

Carbon atoms from CO2 CO2 CO2 C, O, start subscript, 2, and end subscript are fixed (incorporated into organic molecules) and utilized to create three-carbon sugars in the Calvin cycle. ATP and NADPH produced by the light reactions are used to power and support this activity. Calvin cycle reactions occur in the stroma, as opposed to light reactions, which occur in the thylakoid membrane (the inner space of chloroplasts).

That's about it! If you'd like, check out the attachment for a visual!

Thank you,
