Explain how the process of meiosis relates to the way in which a child
prisoha [69]
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. That means that they will never be a copy of their parents because of their different genetic material. Characteristics, such as eye color, hair type and color, the shapes of facial features, and height and build, and attribute the combinations of these to the portions of DNA inherited from each parent which makes them different but still carry the DNA of their parents.

____________ is a membrane protein that catalyzes the energy requiring synthesis of ATP from ADP and inorganic phosphate.
olasank [31]

Answer:

The correct answer will be option-C.

Explanation:

The production of ATP from ADP and Pi (inorganic phosphate) catalyzed by an enzyme known as ATP synthase.

ATP synthase is made up of two main regions called F₀ and F₁ in which F₀ is embedded in the membrane and acts as a pump through which proton flux takes place. The F₁ unit is the rotating unit of the ATP synthase which rotates due to energy provides by the protons during proton flux.

When proton moves through F₀  unit down their concentration gradient, it provides energy to the F₁ subunits which bind ADP and inorganic phosphate to release ATP.

Thus, Option-C is the correct answer.

Identify the phases of meiosis I described below.
lesya [120]

Answer:

The correct phases would be

Homologous chromosomes are separated: It occurs during anaphase I of the meiosis I. It is the third phase of meiosis I during which homologous chromosomes are separated and pulled in opposite direction with the help of spindle fibers.

Homologous chromosomes are paired: It occurs during prophase I. The pairing of homologous chromosomes is termed as synapsis. The pairing is initiated in the zygotene stage of prophase I of the meiosis I.

Nuclear envelopes form around separated chromosomes: It occurs during the telophase I. It is almost opposite to the prophase I. After this phase, cytokinesis takes place.

The centrosome replicates: The replication of centrosome takes place during the S phase of the cell cycle. They migrate to the opposite ends during the prophase.
