3. Observe: Click Add light and look at the Output. What are the products of photosynthesis?
kvv77 [185]

They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration, or converted into starch and stored. Oxygen is produced as a by-product. This process is called photosynthesis.

Hope this helps :D

What is natural selection? ​
lora16 [44]
A theory that states that only the organism with traits that are useful to the environment survive. For example, short-neck giraffes would’ve died out years ago as they can’t reach the trees nor eat grass on the ground.

What is energy coupling?
vagabundo [1.1K]

Answer:

c: the use of energy released from an exergonic reaction to drive an endergonic reaction.

Explanation:

<em>Energy coupling is a process involving two reactions whereby one of the reactions generate energy, and the generated energy is used to drive the other reaction. </em>

A reaction during which energy is generated is referred to as exergonic reaction while one in which energy is consumed is known as endergonic reaction. Hence, energy coupling can also be viewed as a process linking exergonic and endergonic reactions whereby the energy released in the former is used up by the latter.

A good example is illustrated by the light dependent and light independent reactions of photosynthesis during which the ATP and NADPH produced during the light dependent reaction is used to fix carbon dioxide in the light independent reaction.

<em>The correct answer is C.</em>

A BbGg x bbgg cross yields a phenotypic ratio of approximately 5 black eyes, green skin : 5 orange eyes, white skin : 1 black ey
kifflom [539]

Answer:

D.Mendel's law of independent assortment is being violated.

Explanation:

According to Mendel in his law of independent assortment, the allele of one gene gets sorted into gametes independently of the allele of another gene. He discovered this when he performed a cross involving two characters i.e. dihybrid cross, which he obtained a F2 phenotypic ratio of 9:3:3:1. This ratio is only possible if each allele of each gene is represented in each gamete i.e. a dominant allele of the first gene is equally likely possible to be contained with a dominant or recessive allele in the second gene.

If this occurs according to the Mendel's law of independent assortment, a total of four possible combinations of gametes should be produced by each parent organism. When this 4 gametes are crossed in a punnet square, a total of 16 offsprings will be possible.

However, in this case, a total of 12 offsprings were produced, depicting that the alleles did not separate independently of one another to produce four possible gametes.
