Study the picture of the birds. These birds are all types of birds found in the islands of Hawaii and they all evolved from a co

mmon ancestor. How did these birds come to look different?
A) Some offspring were born with slight genetic differences from parents that proved to be an advantage in their current environment.
B) Adult birds faced with a challenge grew different beaks and other traits to fit their environment.
C) Scientists most likely altered their DNA to help them survive.
D) Birds passed on acquired traits to offspring.

Answer: I'm no biology geek, but i believe the answer is D

Explanation:

A: i believe no because it says <u>SOME</u> offspring were born with sight different from parents genetically but in reality all organisms are genetically different due to sexual reproduction

B: no because the traits will have to be passed on over a long period of time and this question does not depict that

C: it's a possibility, but they are talking about evolution and that is artificial selection

D: I was deciding this or a for the right answer, but I thought of what the question was asking and the way that evolution works is desired traits continue, and that those desired traits are passed on generation from generation, which helps the species survive

so i hope this helps :)

I believe this answer is A. answer D sounds very similar,but A goes into detail and gives an explanation. This explains survival of the fittest and is the reason of why organisms evolve.

You eat a candy bar to get you through a late-night studying session. Your body quickly begins to break down the macromolecules
irga5000 [103]

Answer:

a. First Step: The sugars are broken down to simple glucose molecules and the proteins and lipids are broken down to acetyl-CoA molecules. No energy is produced in this first step.

b. Second Step: Glycolysis converts the glucose to two molecules of pyruvate. Six ATP molecules are produced in this step.

c. Third Step: Oxidation of each pyruvate produces two molecules of acetyl-CoA. Six ATP molecules are produced in this step.

d. Fourth Step: Two acetyl-CoA molecules go through the Krebs (citric acid) cycle. Twenty-four ATP molecules are produced through this process.

e. All of the above steps are part of the break down of the candy bar's macromolecules.

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,

Please what is meant by photosynthesis​
Vinil7 [7]

Answer:

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are synthesized from carbon dioxide and water, In most cases, oxygen is also released as a waste product that stores three times more chemical energy than the carbohydrates. Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.
