A plant can have green (G) or yellow (g) leaves. it can also have a long (k) or short (k) stem. A scientist is preparing a Punnett square for a dihybrid cross of a plant with a genotype GGKk what possible gametes can the plant produce?

Answers

Answer:

gk, gK

Explanation:

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

What are Gametes?

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.

What are cell biology, genetics, and
molecular biology?

Answers

Answer:

Explanation:

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).

What relation between cell biology and molecular biology?

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.

What is Mitochondria?

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.

A 10.0 cm3 sample of copper has a mass of 89.6 g. What is the density of copper?

Answers

Answer:

[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.

Answers

Answer:

The individual carrying this beneficial mutation will be selected through natural selection.

Explanation:

Mutations are genetic changes in the DNA sequence. When mutations occur in the germline, these genetic modifications can pass from one generation to the next. In general, mutations are deleterious, but there are exceptions where they may be beneficial for the individual and provide the raw material for evolutionary change. An individual carrying one beneficial mutation will have more chances to survive and reproduce than individuals without this mutation, and thereby such genetic change will increase its frequency in the population.

When an antigen attacks the body, it activates adaptive immunity. This adaptive immunity produces a strong response when it encounters the same antigen for the second time. Which feature of adaptive immunity is essential for this kind of response?

Answers

Answer:

A) the ability to remember the antigen it encounters

Adaptative immunity reacts in a more general way producing nonspecific antibodies against the foreign antigen when the organism is first attacked by that foreign antigen. The second time around, when the organism is faced again with the same foreign antigen, it produces a much stronger response because it memorised the antigen and is not strange anymore so the response can be more specific, quicker, and effective.

Drugs are easy to become addicted to. They can cause substance abuse, which leads to jail time. While drugs also heal people, for example, prescription drugs when used properly are beneficial. They need to be used in restraint because even medically given to you, they are addictive. For example, pain-reducing opioids, though they are helpful they are addictive.
