Under which circumstance does Mendel’s principle of independent assortment hold? a. only when there is crossing over b. only when traits are tightly linked (close together) on the same chromosome c. only when traits are on different chromosomes d. only when the traits are not influenced by selection

Answers

Answer:

c

Explanation:

Mendel's principle of independent assortment holds only when traits are on different chromosomes.

The independent assortment principle states that genes assort independently of one another. In order words, traits are independently inherited by offspring from parents. For example, the trait for eye color is independently inherited from skin color, height is independently inherited from feet size, and etc.

This principle only holds true when genes are located far away from one another on the same chromosome or when they are on different chromosomes entirely. Once genes are close to one another on the same chromosome, they become linked together and no longer independently inherited.

The correct option is c.

2. How does the development of a nervous system and sense organs relate to increasing complexity of multicellular animals?

Answers

The development of nervous system and sense organs in multicellular organisms has led to evolution of species in a more complex manner.

Complexity of multicellular organisms

• The development of nervous system and sense organs has permitted for a greater level of perception and better equipped organisms.

• It has permitted the organisms to collect resources, react to their surroundings, and take advantage of their surroundings.

• This has resulted in the organisms to survive longer and accommodate into bigger types of body.

• Such amendments has thus permitted organisms to become more complex  and move up the food chain.

Thus, the development of nervous system and sense organs is associated with increasing complexity of multicellular animals.

In the thylakoid membranes, what is the main role of the antenna pigment molecules?
a) split water and release oxygen to the reaction-center chlorophyll
b) harvest photons and transfer light energy to the reaction-center chlorophyll
c) synthesize ATP from ADP and Pi
d) concentrate photons within the stroma

Answers

Answer: Option B.

harvest photons and transfer light energy to the reaction-center chlorophyll

Explanation:

In the thylakoid membranes,the main role of the antenna pigment molecules is harvest photons and transfer light energy to the reaction-center chlorophyll because the photon of light move until it get to a molecule in the chlorophyll. When it reaches the molecule, it causes an excitation of electrons in the chlorophyll. The energy then present allow it to break free from the chlorophyll atom, which indicate chlorophyll donating an electron and the energy that is absorbed is then converted to heat.
