Letter X represents the Mitochondria which marks the location where carbon dioxide is produced during respiration. So, the correct option is B.

A mitochondrion is defined as an organelle which is found in the cells of most eukaryotes, such as animals, plants, and fungi that have a double membrane structure. It uses aerobic respiration to generate adenosine triphosphate, which is used throughout the cell as a source of chemical energy.

The main role of mitochondria is oxidative phosphorylation which utilizes the energy released during the oxidation of the food we eat to generate ATP which is used as the primary energy source for most biochemical and physiological processes such as growth, movement and homeostasis.

So, the correct option is B.

Answer:

decrease the base of support and centralize her line of gravity

Explanation:

A wider base of support leads to an unsteady gait. The base of support is the contact between the feet of the soccer player and the surface (the field) supporting him. The root cause of the player's inability to react quickly to the movements of the opposing player is a lack of balance.

Balance is the ability of an individual to sustain the line of gravity which runs the center of gravity. For the player to regain his balance, she needs to decrease the base of support and centralize her line of gravity, so as to maintain balance.

Cell biology (also cellular biology or cytology) is a branch of biology studying the structure and function of the cell, also known as the basic unit of life. Cell biology encompasses both prokaryotic and eukaryotic cells and can be divided into many sub-topics which may include the study of cell metabolism, cell communication, cell cycle, biochemistry, and cell composition.

Genetics, study of heredity in general and of genes in particular. Genetics forms one of the central pillars of biology and overlaps with many other areas, such as agriculture, medicine, and biotechnology. Learn more about the history, biology, areas of study, and methods of genetics.

Molecular biology, field of science concerned with studying the chemical structures and processes of biological phenomena involving molecules. In particular, researchers focus on DNA, RNA, and proteins and their interactions. As a result, the field is closely related to genetics and biochemistry

The study of heredity is a field of genetics and cell biology. The DNA itself (molecular genetics), entire populations, or whole creatures are investigated at various levels of genetics (population and evolutionary genetics).

Two branches of biology are cell biology and molecular biology. The study of cellular mechanisms is a focus of the subject of cell biology.

As a result, it primarily concerns the functions and architecture of the cell. The study of molecular level mechanisms is a focus of the science of molecular biology.

Therefore, cell biology, genetics, and molecular biology are interconnected.

[tex]\boxed {\boxed {\sf d=8.96 \ g/cm^3}}[/tex]

Explanation:

Density can be found by dividing the mass by the volume.

[tex]d=\frac{m}{v}[/tex]

The mass of the copper is 89.6 grams.

The volume is 10 cubic centimeters.

[tex]m=89.6 \ g\\v= 10 \ cm^3[/tex]

Substitute the values into the formula.

[tex]d=\frac{89.6 \ g }{10 \ cm^3}[/tex]

Divide.

[tex]d=8.96 \ g/cm^3[/tex]

The density of copper is 8.96 grams per cubic centimeter.

Answer:

gk, gK

Explanation:

GK, Gk, gk, gK are the possible gametes can the plant produce. So, the correct option is A.

Male and female germ cells are created in the anther and ovule of flowering plants, respectively. Pollen grains, which are discharged from the anthers at anthesis, contain male gametes.

The generative cell relocates through the pollen tube formed by the tube cell during pollen germination to reach the ovary's base where it will be fertilized. The generative cell splits into two male gametes as it moves through the pollen tube.

In the given example, the following gametes could be created while creating a Punnett square:

=> GK (Green and long) (Green and long)

=> Gk (Green and short) (Green and short)

=> gK (Yellow and long) (Yellow and long)

=> gk (Yellow and short) (Yellow and short)

Therefore, the correct option is A.
