Answer:
During meiosis I, the cell is diploid because the homologous chromosomes are still located within the same cell membrane. Only after the first cytokinesis, when the daughter cells of meiosis I are fully separated, are the cells considered haploid.
How does biodiversity affect humans?
Biodiversity affects humans by: underpins the health and has a direct impact on all of our lives. To summarize reduced biodiversity means millions of people face a future where food supplies are more vulnerable to pests and disease, and where fresh water is in irregular or short supply. For humans that is worrying.

What aspect of a muscle cell allows
movement in the body?
A. its shape is short and blunt
B. fibers within the cell move back and forth allowing the
cell to stretch and shrink
C. there are no organelles which allows it to move easier
B is the answer
muscle cells are usually long and have many fibers that can contract and relax.
I'm 100% sure about my answer because I just learned about it :)
The aspect of a muscle cell allows movement in the body is fibers within the cell move back and forth allowing the cell to stretch and shrink. Thus option B is correct.
What is muscle cell?Muscle cell is defined as a unique animal cell that can shrink in size by utilizing a number of motor proteins that have been strategically placed inside the cell.
The cells that make up muscle tissue have the unique capacity to shorten or contract to cause movement of the bodily components.
There are three types of muscle cells.
Cardiac muscleSmooth muscleSkeletal muscleProtein filaments found in muscle cells slide across one another to create muscular contraction.
The configuration of these filaments gives skeletal and cardiac muscle their banded look.
They have a large number of mature mitochondria that supply the energy for muscular contraction.
Thus, the aspect of a muscle cell allows movement in the body is fibers within the cell move back and forth allowing the cell to stretch and shrink. Thus option B is correct.

Stem cells are used to treat some human diseases.
Stem cells can be collected from early embryos. These stem cells have not begun to
differentiate, so they could be used to produce any kind of cell, tissue or organ. The
use of embryonic stem cells to treat human diseases is new and for some diseases,
trials on patients are happening now.
Stem cells can also be collected from adult bone marrow. The operation is simple
but may be painful. Stem cells in bone marrow mainly differentiate to form blood
cells. These stem cells have been used successfully for many years to treat some
kinds of blood disease. Recently there have been trials of other types of stem cell
from bone marrow. These stem cells are used to treat diseases such as heart
disease
Evaluate the use of stem cells from embryos or from adult bone marrow for treating

Hair color is determined by a single gene with a series of alleles, each resulting in different colors. Black, brown, blond and other hair colors are examples of___?
A. incomplete dominance
B. multiple alleles
C. sex-linked trait
D. polygenic traits
Answer:
dissimilar appearence or properties.
Explanation:
Hair color is not so simple as that. Most traits, especially those as complex as color, are controlled by many alleles at many loci. That's why there are different kinds of brown, blond, and red hair in the population. There is no "hair color gene." A fascinating paper came out a few years ago, identifying dozens of SNPs playing a role in hair and eye color. It's a deep, deep rabbit hole that we have only begun to plunge into.

Explanation:
Over 99.9% of the solar system is composed of hydrogen and helium. How does this help to explain the size differences between the terrestrial planets and the gas giants?
Explanation:
Gas giants/Jovian planets are also called the outer planets, they are made of gases, they are large and less dense, more moons. Terrestrial/Rocky planets are also called the inner planets. They are made of rocky surface, denser than Jovians, and small, little or no moons.
The information about the composition of solar system has great significance in providing data about size between the terrestrial planets and the gas giants planets.
The size differences occur between the terrestrial planets and the gas giants due to the presence of different concentration of gases in their compositions. Gas giants planets are also called the outer planets which are made up of gases.
They are large in size but having less density and more moons while on the other hand, terrestrial planets are made of rocky surface. They are also called the inner planets. They are more denser than gas giant planets, small in size and less or no moons so we can conclude that there is a great size differences between the terrestrial planets and the gas giants.

Write a paragraph explaining how adhesion, cohesion and capillary action all enable water to go from the roots to the top of a tall tree.
Answer:
Capillary action helps bring water up into the roots. But capillary action can only "pull" water up a small distance, after which it cannot overcome gravity. To get water up to all the branches and leaves, the forces of adhesion and cohesion go to work in the plant's xylem to move water to the furthest leaf.
Explanation:
Hope This Helps!
Water is moved up through the plant by capillary action from the soil.
Hydrogen connections between water molecules give them a sticky property that allows them to form droplets. Droplets can stick to the plant because of adhesion.
what is capillary action?Capillary action is the movement of liquid along a solid's surface induced by the attraction of the liquid's molecules to the solid's molecules.
The movement of a liquid across the surface of a solid induced by adhesion between the two is known as capillary action.
The higher the water climbs on its own, the narrower the tube becomes. Water is forced up the columns of cells in the xylem and through fine tubes in the cell wall by adhesion in plants.
The transport of water through the plant is known as capillary action. When the adhesion is stronger than the cohesion, this movement happens. The attraction between water molecules is natural. The transient hydrogen bonds that they form are the source of their attraction.
what is adhesion and cohesion?The act of attaching one thing to another is known as adhesion. Water adheres to the organic tissues of plants thanks to adhesion.
Cohesion is the property that allows molecules of the same substance to stick together.
Water molecules are held together by cohesion in plants. Intermolecular attraction leads liquids to create a top or outer layer that acts like a thin film.
The shape of water drops is determined by surface tension, which also holds structures together as they absorb water.

Using context clues, what does “ferrying its newly-gained energy with it “ mean when talking about convection?
The term "ferrying its newly-gained energy with it" means that the fluid carries the energy it acquired as it rises during convection.
Convection is a mode of heat transfer in which energy is transferred by the bulk movement of particles from one point to another. During convection, a fluid is heated and its particles acquire energy, These energetic particles now move upwards and are replaced by less dense fluid at a lower energy.
The term ferrying its newly-gained energy with it, implies that the heated particles carry the energy they have gained with them as they rise during convection.
