The cell membrane is present during the whole cycle. The nuclear cell breaks and then is regenerated.<em> At some point in their life cycle, all cells have a _</em><u><em>cell membrane</em></u><em>_, whereas not all cells have a(n) _</em><u><em>nuclear cell</em></u><em>_</em><em>.</em>

<h3>What happens to the membrane during cell cycle?</h3>

The cell cycle involves two stages. First occurs the interphase, and after that cell division. During the interphase, the cell prepares for division, duplicating its size, its content, and genetic material.

During the prophase, the <u>nuclear membrane </u>breaks. Cell division occurs (either mitosis or meiosis), and at the end of the cycle, the nuclear membrane regenerates again (during the telophase).

Finally, cytokinesis occurs in which through invagination of the cell membrane, the cell divides into new cells.

The cell membrane is present during the whole cycle, protecting the cell content. The nuclear cell breaks and then is regenerated.

Explain why the formation of abscission layer causes sugar to accumulate in leaves.

kramer

Abscission layer is the layer of cutinized parenchyma cells that develops in the abscission zone. The abscission zone form across the base of the plant part, where the break eventually occurs. During the photosyntesis chlorophyll using sunlight produces sugar and storches which are used as food by plant. And sugar accumulate in leaves.

How do mountain barriers modify rainfall patterns on Hawaii's Big Island and island of Maui?

Iteru [2.4K]

The explanation is given below

<u>Explanation:</u>

Hawaii's Big Island:

Mountain barriers play a significant role in modifying the air masses and topography affects the distribution of precipitation.

The orographic effect takes place on Hawaii's Big Island (i.e) the rising air makes the windward side of the mountains rainy and leeward side of the mountains dry.

Island of Maui:

In the Island of Maui, the high mean of rainfall is found on the windward side of the mountain slopes and the low mean of rainfall is found on the leeward lowlands and on upper slopes of the highest mountains.

In corn, the allele A allows the deposition of anthocyanin (blue) pigment in the kernels (seeds), while aa plants have yellow ke

lara31 [8.8K]

Answer:

Explanation:

As given,

Allele A for blue anthocynin.

aa for yellow kernel;

at second locus;

W produce smooth kernel,

ww for wrinkled kernel;

Parents as given are: AaWw and aaww

Progeny are:

blue smooth ( AaWw)= 1447;

blue wrinkle (Aaww)= 169;

yellow smooth (aaWw)= 186;

yellow wirnked (aaww)= 1510

Recombinant progeny are 169+ 186= 355

non- recombinant progeny are = 1447+ 1510= 2957

so recombination frequency (RF)= 346/2957×100= 12.0054%

So a and w are linked genes.

They are 12 mu far away from each other.

b) Blue smooth parent= AaWw.

c) Aaww crossed with aaWw

progeny are= AaWw, Aaww, aaWw, aaww,

They all are produced in same proportion =0.25% or 1/4.

Suppose an experimenter becomes proficient with a technique that allows her to move DNA sequences within a prokaryotic genome.

Vladimir [108]

Answer:

D) The structural genes will be transcribed continuously.

Explanation:

Suppose an experimenter becomes proficient with a technique that allows her to move DNA sequences within a prokaryotic genome. If she moves the operator to the far end of the operon, past the transacetylase (lacA) gene, the structural genes will be transcribed continuously.

A structural gene is a gene that codes for any RNA or protein product other than a regulatory factor (i.e. regulatory protein).
