What is one condition that must be met for a population to be in genetic equilibrium?
Answer:
Hardy-Weinberg equilibrium
Explanation:
In order for the population's gene pool frequencies to remain constant, the Hardy-Weinberg equilibrium must be met. Random mating, no mutation, migration, or natural selection must all be present, as well as a big sample size.

Using a simple aproxamation above,calculate the volume of the right circular cylinder with a radius of 2 meters and a height of 9 m
Answer:
Volume = 113.112 m³
Explanation:
Given the following data;
Radius = 2 meters
Height = 9 meters
To find the volume of a right circular cylinder;
The volume of a right circular cylinder is calculated by multiplying the area of its circular base with the height of the cylinder.
Mathematically, the volume of a right circular cylinder is given by the formula;
Volume= πr²h
Where;
r is the radius of the circular base.
h is the height of the cylinder.
Substituting the values into the formula, we have;
Volume = 3.142 * (2)² * 9
Volume = 3.142 * 4 * 9
Volume = 113.112 m³

When glucose is unavailable, the liver begins to break down fatty acids to supply the rest of the body with metabolic fuel. Explain why fatty acid-derived acetyl-CoA is not catabolized by the citric acid cycle but is instead diverted to ketogenesis when no glucose is available.
Answer:
Fatty acid degradation produces acetyl-CoA
When carbohydrate concentrations drop, any available oxaloacetate is diverted to gluconeogenesis to produce the glucose necessary for red blood cell and brain function. If acetyl-CoA cannot enter the citric acid cycle (and acetyl-CoA cannot be converted to pyruvate in mammals), it is converted to ketone bodies.

Suppose you traveled back in time and located the first animals to have evolved feathers. You found that these animals were tree-dwelling ectotherms, able to run quickly but unable to fly. You also noticed that only males had feathers. Which hypothesis of feather evolution would these data most support? Feathers initially evolved in a role associated with ________.
Answer:
Feathers initially evolved in a role associated with sexual selection.
Explanation:
In species where only males had feathers, these feathers can be considered to have evolved into a role associated with sexual selection. This is because in these species, males used their feathers as a sexual attraction for females, in this case, females chose the males that had more attractive feathers to mate and generate new individuals for the species. An example of this can be seen in the peacock, where the tail with lush feathers is only present in males and is intended to sexually attract females.

what is the prediction of the outcome.genetic crosses between various organisms
Answer:
The results of genetic crosses can be predicted using a chart called a Punnett square. In a Punnett square, the possible male and female gametes of each parent are written across the side and top of the square. The interior squares represent every possible combination of gametes that could combine to form a zygote.
Explanation:
To fill in the square, look at the alleles of the games on the outside edges and bring them across and down to fill in the center of the square. If the offspring is heterozygous, we will write the capital letter in front of the lower case letter.
In the example below T=tall plants and t= short.

D. It has few resources.
The correct answer is C. The birthrate is higher than the death rate.
Explanation
The graph is about the growth of the world population, this shows the population growth of the world, Asia, Africa, Europe, United States, Canada and Greenland, Mexico, Central America, Caribbean Islands, and South America, and Oceania (Australia and nearby islands in the Pacific). This graph covers the time from 1950 to 2050 divided into decades. In the specific case of Africa in 1950 it had a population of close to 300 million people. Subsequently, in 2010 the population of Africa was close to 1 billion people and the projection for the year 2050 is 2 billion people. According to this, it can be concluded that the birth rate is higher than the death rate because the population has a growth trend, which indicates that more people are born than die.

All of its cells are electrically connected via gap junctions. All of its cells are sparsely distributed in the extracellular matrix.
Answer:
Connective tissue is a group of tissues in the body that keep the body and its organs in shape while also providing cohesion and internal support.
All of its cells exist sparsely distributed in the extracellular matrix is the best description of connective tissue.
What is connective tissue?
Tissue that sustains, protects and provides structure to other tissues and organs in the body. Connective tissue also stores fat, permits the movement of nutrients and other substances between tissues and organs, and allows the repair of damaged tissue. Connective tissue exists created up of cells, fibers, and a gel-like substance.
Connective tissue is discovered in between other tissues everywhere in the body, including the nervous system. The three outer membranes (the meninges) that surround the brain and spinal cord exist composed of dense inert connective tissue.
Connective tissues bind systems together, form a framework and support for organs and the body as a whole, store fat, transport substances, defend against disease, and assist restoration of tissue damage.
Hence, All of its cells exist sparsely distributed in the extracellular matrix is the best description of connective tissue.

The word kinetic comes from the Greek word Kinetikos, which means motion.
1) GPE = 100 J
mgh = 100
Therefore, height above the ground,
h = 100/mg = 100/(2 x 9.8)
h = 5.1 m
2) The word kinetic comes from the Greek word Kinetikos, which means motion.
3) Displacement is the measure between the difference in start and end positions.
4) Satellite is an object called that orbits another object.
5) v = s/t
v = 10/1v = 10 m/s
6) According to Newton's second law, F ∝ a. So, when the car's acceleration triples, the force on the car also triples.
7) Kinetic energy, KE = 1/2mv²
