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:
The correct answer would be C. With an input of energy, ADP combines with a phosphate group to become ATP.
Inorganic phosphorus and energy are added to adenosine diphosphate (ADP) in order to convert it to adenosine triphosphate (ATP).
This reaction is usually catalyze by the enzyme ATP synthase. It present in inner membrane of mitochondria of the cell as well as in the thyllakoid membrane in chloroplast.
ATP synthase uses the energy provided by chemiosmosis i.e. flow of protons down the gradient across the membrane through this enzyme. Proton gradient is formed either by photosynthesis or by cellular respiration.
ADP + inorganic phosphate (Pi) + energy → ATP + H₂O
ATP is used as the energy currency of the cell which breaks down to release inorganic phosphate group and energy which is used in various metabolic processes.
Answer:
A XY or XY gamete fuses with a normal gamete (X or Y)
Explanation:
Meiotic nondisjunction is the phenomenon whereby chromosomes fail to separate during meiosis I or II. Meiotic nondisjunction leads to the formation of abnormal gametes I.e. gametes with additional or missing chromosomal piece.
The fusion of these abnormal gametes produced by nondisijuction with a normal gamete (X or Y chromosome). This leads to a condition called ANEUPLOIDY, which is a chromosomal disorder. In the case od Calix, XXY is an ANEUPLOIDY state that could have resulted because there was a fusion between a XX gamete and Y gamete or XY and X. The XY or XX gametes are produced as a result of nondisijuction.
Answer:
These group of muscles called erector spinae muscles arises from a tendon in the sacral area and pelvis, it extends up to the occipital bone.
Erector spinae muscles originates from the SPINOUS PROCESSES of T9-T12 of the thoracic vertebrae and inserts into the SPINOUS PROCESSES of T1-T2 of the cervical vertebrae
They therefore run vertically on either side of the spine (medially and laterally).
The periodic table only accounts for elements. It does not account for compounds, such as water.
