A: Mitochondrion
Just remember that the mitochondria are the powerhouse of the cell!
Answer:
Depending on the way it is I believe it should be organ system the way I'm used to listing it.
Explanation:
It could be different though.
B. The Y chromosome doesn't experience crossing-over.
C. The mitochondria DNA in a mother and her offspring vary greatly.
D. The X chromosome can only be passed from a father to his son.
The identification of an individual by the means of genetic engineering is possible because the Y chromosomes in the males does not experience any crossing-over as there is only a single Y chromosome present in a human male.
The mitochondrial DNA is passed from the mother to child in the cytoplasm of the cell, and it is passed on without any changes. The X chromosome is can be passed from a mother to her son as he will receive Y chromosome from his father.
Hence, the correct answer is 'Option B - The Y chromosome does not experience crossing over'.
The correct answer is this: A CUB TIGER BEGINS TO GROW.
Mitosis is the biological process by which a cell divide into two identical cells. The major reasons why cells undergo mitosis is to bring about growth and to replace worn out cells. The process of mitosis is divided into five stages, which are: interphase, prophase, metaphase, anaphase and telophase. The somatic cells are the ones that usually undergo the process of mitosis.
A cub tiger beginning to grow is the stage in which mitosis is most important and is denoted as option C.
This is a type of cell division in which the parent cell produces two identical daughter cells.
This is involved in the growth and replacement of worn out tissues in organisms in the ecosystem which is why the growth of tiger cubs best represents it.

The base paring that occurs during DNA replication is Adenine to Thymine, Thymine to Adenine, Cytosine to Guanine, Guanine to Cytosine.
During DNA replication, specific base pairings occur that ensure accurate and faithful duplication of the genetic information.
DNA consists of four nucleotide bases:
adenine (A),
thymine (T),
cytosine (C), and
guanine (G).
The base pairing rules are as follows:
Adenine (A) always pairs with Thymine (T).
Thymine (T) always pairs with Adenine (A).
Cytosine (C) always pairs with Guanine (G).
Guanine (G) always pairs with Cytosine (C).

b. chemical changes and flow of water
c. physical changes and flow of energy
d. physical changes and flow of water
Answer:
a. chemical changes and flow of energy
Explanation:
Energy flow from one organisms of one tropic level to other, matter cycling and transformation of energy are the functions that sustain the ecosystem. Transformation of solar energy into chemical energy by plants serves as energy source for all heterotrophic living beings in the system. The heterotrophic organisms digest the ingested food (chemical change) to release energy to support their life processes. The energy stored at one tropic level is carried to next tropic level via food chain and food webs and represents the interaction between living components of ecosystem.
