what function does the electron transport chain play in the light- dependent cycle of photosynthesis ?
romanna [79]

Answer:

The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.

A cell with 80 chromosomes undergoes meiosis. How many chromosomes are found in the daughter cells? How many daughter cells are
qwelly [4]

Answer:

Four daughter cells are produced each with 40 chromosomes. The daughter cells would exhibit genetic variations and would not be genetically identical to each other.

Explanation:

Meiosis is a cell division that forms four daughter cells from one parent cell as two sequential division meiosis I and meiosis II do not include any DNA replication between them. Crossing over during prophase-I of meiosis-I includes the exchange of genetic segments and occurs between the homologous chromosomes. It produces new gene combinations in the daughter cells which were otherwise not present in the parent cell.

Since there is no DNA replication between meiosis I and meiosis II, the daughter cells have half the number of the chromosomes compared to the parent cell. This occurs as homologous chromosomes move towards the opposite pole during anaphase I.

Therefore, a parent cell with 80 chromosomes will make a total of 4 daughter cells by meiosis. Each daughter cell would have 40 chromosomes. These daughter cells would have some new gene combinations and would be genetically dissimilar among themselves.

Organisms that expend energy to regulate some or all of their internal conditions are known as?
seraphim [82]
<span>Organisms that expend energy to regulate some or all of their internal conditions are known as regulators. Regulators are organisms that can control their internal environment regardless of external environmental change. Regulators achieve this by homeostatic mechanisms and it requires a lot of energy. Examples of regulators are mammals and birds</span>

In-s [12.5K]

Answer: B. Speed up the chemical reaction

Explanation: Enzymes help speed up chemical reactions in the human body. They bind to molecules and alter them in specific ways. They are essential for respiration, digesting food, muscle and nerve function, among thousands of other roles.

How does crossing over affect the genes being passed on to the offspring??
Lina20 [59]
Crossing over, or recombination is the exchange of chromosome segments between non sister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.
