Mastering biology Chapter 13 - Question 3 - Multiple Choice Homology is evidence of ________.
Fudgin [204]

Answer:

Homology is evidence Divergent Evolution

Explanation:

When we study DNA sequences from different species, we conclude that all the living organisms have been arise from a single common ancestor and due to homology between different species, it is also concluded that organisms now-a-days are a result of Divergent Evolution from a single common ancestor.

What is the expected phenotypic ratio for a cross between two individuals that are heterozygous for a given trait? Use one of Me
svetlana [45]

The expected phenotypic ratio for a cross between two individuals that are heterozygous for a given trait is 3:1.

<h3>What is Phenotype?</h3>

This is referred to the physical characteristics of an organism such as the size, shape etc.

When two heterozygous traits are crossed:

Rr ×  Rr ⇒ RR Rr Rr rr

The ratio is therefore 3:1 of the dominant to recessive phenotype.

*Fill in the blank*
Gekata [30.6K]

The noncyclic pathway is a FLOW of electrons from water, to photosystem II, to PHOTOSYSTEM I to NADPH. Energy is released  as  ELECTRONS  move through the first electron transfer chain. This energy pumps HYDROGEN IONS  into the thylakoid compartment, and then they power the formation of ATP as they flow back out. Sunlight provides the energy needed to keep this cycle going.

----------------------------------------------------------------------------------------------------

  1. Luminous energy is trapped by chlorophyll in Photosystem II.
  2. When the pigment molecules absorb light, electrons provided by water molecules get in a higher energy level.
  3. The excited electrons go through the electron transport chain from Photosystem II to a less energetic level in photosystem I.
  4. <em>When the excited electrons leave photosystem II, they are replaced by new electrons extracted from the water molecules. </em>
  5. Luminous energy absorbed move the electrons from the photosystem I to another electron acceptor, from where they get transported again and used to produce NADPH molecules.
  6. <em>When electrons leave Photosystem I, they are replaced by new electrons coming from photosystem II. </em>
  7. When the water molecule breaks down, hydrogen ions remain in the thylakoid lumen, from where they are pumped to the stroma by the ATP synthase.
  8. The released energy is used to produce ATP molecules.
  9. Hydrogen ions go back from the stroma to the thylakoid compartment.

The final products are oxygen, ATP, and NADPH.
