what is created in the capsule?

Answer:

C

Explanation:

Answer:

Variation. There must be variation in the traits of the individuals in the population, and some of this variation must be heritable, meaning it can be passed on to offspring.

Inheritance. The traits that vary among individuals must be encoded in the genes or have a genetic basis. Otherwise, they could not be inherited by the next generation.

Differential survival and reproduction. Individuals with certain traits must survive and reproduce more successfully than others in a given environment. This means that they have a higher fitness, or reproductive success, than others.

Time. Evolution by natural selection takes place over many generations. It is not a one-time event, but a gradual process of change in the population.

If these factors are present, then natural selection is likely to be the mechanism of evolution for that species. Natural selection causes populations to become adapted, or increasingly well-suited, to their environments over time2.

Explanation:

To find the time it takes for the truck to cover 2200 km at a speed of 80 km/hr, we can use the formula:

time = distance/speed

Substituting the given values, we get:

time = 2200 km / 80 km/hr

Simplifying the expression, we get:

time = 27.5 hours

Therefore, the trip lasts 27.5 hours.

This indicates how quickly or slowly an object moves. It discusses the distance traveled divided by the time needed to cover it. Time = Distance/Speed, as the speed builds the time taken will diminish as well as the other way around.

When a pea plant inherits two copies of the recessive allele (pp), it is unable to produce the functional enzyme needed for the production of the purple pigment, resulting in the white phenotype. The white phenotype indicates that no pigment is produced by the flower-color gene, rather than a different pigment being produced.

The white phenotype in pea plants occurs when an individual inherits two copies of the recessive allele for flower color (pp) from its parents. In this case, the individual does not produce the purple pigment that is typically associated with the dominant allele (P).

This is because the recessive allele does not produce a functional protein that is necessary for the production of purple pigment.

In pea plants, the flower-color gene is responsible for encoding an enzyme that is involved in the synthesis of the purple pigment. The dominant allele (P) produces a functional version of this enzyme, which allows for the production of the purple pigment.

However, the recessive allele (p) produces a non-functional version of the enzyme, which is unable to produce the purple pigment.

The theory of plate tectonics describes the movement and interaction of large plates that make up the Earth's lithosphere (the rigid outer layer of the Earth) over the more fluid asthenosphere (the partially molten upper mantle). The theory suggests that the Earth's lithosphere is broken up into several large plates that are in constant motion, and that the continents on Earth are part of these plates.

According to the theory of plate tectonics, the continents are not fixed in place, but instead they have moved over geological time scales due to the movement of tectonic plates. The plates move apart at divergent boundaries, where new oceanic crust is formed, and they move towards each other at convergent boundaries, where one plate subducts beneath the other. The movement of these plates has led to the formation of mountain ranges, the creation and destruction of ocean basins, and the distribution of organisms around the globe.

The theory of plate tectonics also explains the occurrence of earthquakes, volcanic eruptions, and the formation of many geological features. It is an essential concept in the study of geology, providing a framework for understanding many of the Earth's geological processes, and has greatly contributed to our understanding of the evolution of the Earth's surface over time.

Hydrostatic equilibrium is a state of balance in which the inward force of gravity is matched by the outward pressure of gas and radiation.

This can be thought of as an equally matched battle between the weight of the gas in a star, which pulls everything inward, and the outward pressure of radiation and gas, which pushes everything outward.

The pressure comes from the heat generated by nuclear fusion in the star's core, and it's this pressure that keeps the star from collapsing under its own weight. In other words, hydrostatic equilibrium is what keeps a star stable and prevents it from either collapsing or exploding.

It's an essential concept in astrophysics and helps us understand how stars work and how they evolve over time.

Answer:Ice has a lower density than liquid water because it has more space between molecules. Therefore, the correct answer is D.

Explanation:

When water freezes into ice, its molecules arrange themselves into a crystal lattice structure, which causes the molecules to be spaced farther apart than they are in liquid water. This means that ice has a lower density than liquid water, which is why ice floats on top of liquid water. When water freezes, the molecules lose some of their kinetic energy, causing them to lock into a more rigid structure, which takes up more space. In contrast, liquid water has more kinetic energy, which allows the molecules to move more freely and take up less space.

Indirect and direct renal mechanisms both play vital roles in regulating blood pressure. The indirect renal mechanism, also known as the renin-angiotensin-aldosterone system (RAAS), involves the release of renin by the kidneys in response to low blood pressure.

Indirect and direct renal mechanisms both play vital roles in regulating blood pressure. The indirect renal mechanism, also known as the renin-angiotensin-aldosterone system (RAAS), involves the release of renin by the kidneys in response to low blood pressure. This enzyme converts angiotensinogen to angiotensin I, which is then converted to angiotensin II. Angiotensin II narrows blood vessels and stimulates the release of aldosterone, leading to sodium and water retention, ultimately increasing blood pressure.

The direct renal mechanism, on the other hand, is the result of the kidneys' filtration and reabsorption processes. When blood pressure increases, the kidneys filter and excrete more water and sodium. This leads to a decrease in blood volume and a subsequent reduction in blood pressure. Conversely, when blood pressure decreases, the kidneys retain more water and sodium, increasing blood volume and raising blood pressure.

In summary, both indirect and direct renal mechanisms work together to maintain optimal blood pressure. The indirect mechanism relies on hormonal regulation via RAAS, while the direct mechanism involves the kidneys' filtration and reabsorption processes.
