The right answer is Y (G2 phase).
The interphase is the moment when the cell lives and does everything for which it is programmed. She is also preparing to divide. The steps of the division are detailed below:
Phase G1 (W) comes from a word "GAP" (= interval). During this phase, the cell performs its normal metabolism, it grows to a critical size that will give the signal to move to phase S which consists of replicating the nuclear DNA (X).
Once DNA replication is complete, phase G2 begins (The letter Y). Here, the growth of the cell end, but it will continue to fulfill its functions. During this phase, the centrosomes replicate, they will allow the smooth course of the mitosis. This phase ends by passing the G2 checkpoint, where the mitosis begins.
The shortest phase (Z) is M phase (mitosis / meiosis).

Answer:
c
Explanation:
Im pretty sure, so sorry if I'm wrong though.
The steroids are produced by the Smooth endoplasmic reticulum.
The cells, which are involved in the secretion of the steroid molecules have an abundant number of the smooth endoplasmic reticulum, which is abbrevated as SER.
The cells present in the ovary and the testis have a large number of smooth endoplasmic reticulum. The abundant number of smoothe endoplasmic reticulum allow them to produce a large amount of steroid molecule to produce the steroid hormones estrogen and testosterone.
Hence, in this case, the ovarian cells would have a large number of SER.
Answer:
Organism in a lichen that provides protection - algae
Organism in a lichen that provides nutrients through photosynthesis - algae
Branched growth form of lichen - fruticose
Leafy growth form of lichen - foliose
Small and flat growth form of lichen - crustose
Explanation:
<em>Lichens are composite organisms that are formed from symbiotic relationships between fungi and cyanobacteria/algae. The Green algae layer offers food to the fungi by photosynthesis while the latter supplies nutrients and offers protection to the algal component. </em>
There are different types of lichen based on the growth structure:
Fruticose lichens grow upright and shrubby and posses either round or flat branches.
Foliose lichen appears like a leaf with upper and lower layers. They are usually flat or convoluted in nature.
Crustose lichens are small in appearance with flat, crusty growth on surfaces on which they grow.
