what is genetic equilibrium? what conditions are required to maintain genetic equiibrium?
The genetic equilibrium represents the condition of a genotype or an allele in the genetic pool of a particular population, where there are no changes in the frequency in the successive generations. This basically means that the population has managed to reach the peak of its evolution for the environment in which it leaves, so there's no evolutionary pressure for changes.
In order for the genetic equilibrium to be maintained for prolonged period of time, the population should not face any evolutionary pressure that will cause changes in it. In essence, this means that the environment in which the population lives should remain exactly the same as it is for longer period of time, so the population will have no need to change its appearance or behavior.

What type of cell is prepared to live on its own?
A. Viral cell
B. Unicellular cell
C. Eukaryotic cell
D. Multicellular cell
Answer: A unicellular
Explanation: The entire body is unicellular therefore it can live on it's own
Final answer:
The type of cell that is prepared to live on its own is a unicellular cell (Option B).
Explanation:
Unicellular organisms are made up of a single cell that carries out all the functions necessary for life. In contrast, a eukaryotic cell (Option C) may be part of a multicellular organism and relies on a community of cells to survive. Viruses (Option A) are not considered living because they require a host cell to replicate. Multicellular cells (Option D) are individual cells that are part of a larger organism consisting of many cells, and they cannot live independently.
The presence of a membrane-enclosed nucleus is a characteristic of eukaryotic cells (Option B). Eukaryotic cells have membrane-bound organelles, including a nucleus, which differentiates them from prokaryotic cells which do not have a membrane-bound nucleus.
Lastly, a note on viruses: they are not considered living organisms as they are acellular, meaning they are not made up of cells. They are obligate parasites that require a host to replicate. Therefore, they cannot be categorized with cellular life such as unicellular or multicellular organisms.
What causes the oceans to bulge near the equator compared to seawater at the poles?
A. Thermohaline circulation
B. The Coriolis effect
C. Centrifugal force
D. Convection
Answer:The answer is C. Centrifugal force
Explanation:
Answer:
The Centrifugal force makes the seawater to bulge at the equator when compared to the seawater at the poles.
Explanation:
The centrifugal force drives the earth rotation due to the bulging known as the equatorial bulging. But it is a different effect from tidal bulging.
Relatively the tidal effects are caused by the gravitational gradients that mean the differences in the gravity from one point to another point in the earth.
So centrifugal force is the reason for the bulge of seawater at the equator.

How are the reactants represented in the chemical equation for photosynthesis?
Answer: The equation for photosynthesis states that the combination of carbon dioxide, water and light energy produces a carbohydrate (glucose) and oxygen. The chemical formula is 6CO2 + 6H2O + light energy = C6H12O6 + 6O2. ... This translates to the production of glucose and oxygen from carbon dioxide and water.
I hope this helps you
please mark my answer as brainliest
The two reactants in the chemical equation for photosynthesis are carbon dioxide and water.
What is photosynthesis?Photosynthesis is the conversion of light energy into chemical energy by green plants and other organisms. Light energy is collected and utilized by green plants during photosynthesis to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic molecules.
6CO₂ + 12H₂O --> C₆H₁₂O₆ + 6O₂ + 6H₂O is the general formula for photosynthesis.
The photosynthesis equation indicates that when carbon dioxide, water, and light energy are combined, a carbohydrate (glucose) and oxygen are produced. This leads to glucose and oxygen is produced from carbon dioxide and water.

Which of the following would be produced by meiosis? red blood cell cells of the stem in plants sperm cell epithelial cell
meosis cell division occurs in reproductive cells and sperm cell is one of the reproductive cells.
Answer:
The correct answer is option-sperm cell.
Explanation:
Meiosis is a type of cell division which produces cells with different genetic material. It produces different genetic material.
Since meiosis is involved in the production of four daughter cells with reduced genetic material that is 'n' from 2n parental cells, it is involved in the production of gamete cells that is sperm cells.
Thus, the option-sperm cell is the correct answer.

which of the following statements about metallic bonds is false
A.The resulting compound has low and melting and boiling points.
B. the resulting compound has a shiny surface
C. the resulting compound is a good conductor or electricity
D. the resulting compound cannot be dissolved in water.
- Its A! they have high melting/boiling points.
Metallic bonds do have shiny surfaces (hence, the name metallic).
Metallic bonds are good conductors of electricity.
Metallic bonds cannot be dissolved in water.
The correct answer is option A.
-the resulting compound has low melting and boiling points
Answer:
The resulting compound has low and melting and boiling points.
Explanation:
Metallic bond: It is the type of bond (chemical) that hold the atoms of metal together, it forms when the electrostatic attractive force present between conduction electron and fixed positive charge metal atoms. So, metal atoms have high melting and boiling point. This means that they take lot of energy to overcome these Forces (electrostatic) during melting and boiling time.
It also describes as the sharing of free electrons between the structure of positively charged ions.

Explanation:
A(n) ___ forms along the boundaries where two contrasting air masses meet
I believe the answer is a front
Answer:
Air Front
Explanation:
The transition zone between two distinct air mass is known as the front. The presence of the air front in an area indicates the change in the weather pattern causing heavy rainfall, thunderstorms, hurricanes, tornadoes, and blustery wind.
This air front is mainly divided into 4 types. They are as follows-
(1) Warm air front- In this type of front, the warm air replaces the cold air mass.
(2) Cold air front- In this type of front, the cold air replaces the warm air.
(3) Occluded air front- When a warm air mass occurs in between two cold air mass, then it is known as the occluded air. It results in heavy rainfall and powerful wind.
(4) Stationary air front- When both the warm and cold air occurs simultaneously and there occurs no replacement of one another, then it is known as the stationary type of air front.

According to the principle of segregation, what kind of gametes can an individual with the genotype Bb produce?
A. b only
B. B and b gametes
C. B only
D. B, b, and Bd gametes
Answer:
B
Explanation:
50% B allele, 50% b allele
Answer:
Option B, B and b gametes
Explanation:
As per the principle of segregation, a chromatin containing alleles in pair (which expresses certain trait) gets separated during the cell division and lead to formation of new offspring with a varied genotype. This principle of seggregation is very important in producing diverse species from one generation to other.
Hence, option B is correct.
a major misconception about natural selection is that this mechanism "gives organisms what they want or need so they can adapt to an enviornment" Explain why this is incorrect.
Natural Selection is the process by which organisms with higher fitness and adaptations better suited to their environment tend to survive, while organisms with unfavorable variations do not. Natural selection works with the traits and adaptations already present in the organism, and simply selects the favorable ones.
