Answer:
The process of meiosis involves cell division in which results in 4 daughter cells. Each cell has half the number of chromosomes of the parent cell. Genes are what determine what each cell obtains. A unit of genes is transferred from a parent to offspring. In some cases they are spreaded equally among the eggs therefore creating identical twins. While in other cases they are not distributed in variation, creating fraternal twins.
The two girls in the images do not look identical due to there being two separate eggs that were fertilized by the sperm. Independent assortment causes genes to separate from each other when reproductive cells develop. Variation defines the difference between the DNA in two individuals. Crossing over happens when the exchange of genes between homologous chromosomes results in parental mixture to the offspring. When this occurs, the genes are uniquely developed between the two eggs.
As you can see, the methodology for the making of two non-identical twins posses a series of steps. A variation of features is created due to genes determined by independent assortment. Meiosis is what divides the cells into daughter cells for fertilization by the sperm. All of which was talked about holds a great purpose in the process.

Answers
Answer:
All ecosystems are made up of abiotic and biotic components.
biotic factors are living things, such as plants or animals.
abiotic factors are nonliving things, such as wind, temperature, or moisture.
producers are organisms that get their energy from nonliving resources, meaning they make their own food. These organisms are also called autotrophs.
consumers are organisms that get their energy by eating other organisms. These organisms are also called heterotrophs.
Why are producers so important to an ecosystem?
They create the base of the food chain/food web
Explanation:
The answers can be explained as:
1.Ecosystem is made up of biotic and abiotic compoenents. Biotic components refer to the living things whereas the abiotic components are the water, soil, air, and minerals.
2. Biotic factors are the living components of the ecosystem, which are plants, animals, and microorganisms.
3. Abiotic factors are the non-living components, which include moisture, temperature, air, and minerals.
4. Producers are the organisms that prepare food in the presence of light, water, and gases. These organisms are also plants or autotrophs.
5. Consumers are the organisms that feed on the producers to obtain energy. These organisms are known as heterotrophs.
6. Producers are the organisms that prepare food for the organisms. These are essential for the ecosystem as all organisms are dependent on each other and require food for survival.

Where does sugar enter the blood? B. How can you tell where sugar enters the blood? C. Where is sugar removed from the blood? D. How can you tell?
Answers
Answer:
Well,
Explanation:
For your first question, the intestines.
B.When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose. The stomach and small intestines absorb the glucose and then release it into the bloodstream.
C. The capillaries.
D. Glycogen is mainly stored in the liver (where it makes up as much as 10% of liver weight and can be released back into the blood stream) and muscle (where it can be converted back to glucose but only used by the muscle). Therefore, excess glucose is removed from the blood stream and stored. In short terms, when it has the lowest content.
Blood sugar or glucose is the major source of energy found in the body. It is derived from the food and nutrient an organism consumes.
A. The blood sugar enters the intestine, where it gets digested. This absorbed sugar then gets discharged in your blood from where it diffuses in the body as a source of energy.
B. The food in the stomach gets divided into smaller, simple compounds as the carbohydrates split into sugar and starch.
It further gets divided into glucose which is the simplest sugar. The glucose then gets absorbed by the stomach and intestine which later discharges into the blood.
C. The excess glucose gets expelled from the blood capillaries and gets stored in the form of glycogen.
D. The excess glucose in the form of glycogen gets collected in the liver cells and muscles, where they can be transformed back into glucose through the process of glycogenolysis.

A teacher has two cubes of sugar that are both the same size and shape. He adds cube A to a beaker filled with 100 mL of water, and the cube completely dissolves in the water. He then places cube B on a glass dish over a flame. He keeps the dish over the flame until cube B has turned completely black. Once cube B has cooled off, he adds it to another beaker filled with 100 mL of water. Cube B does not dissolve in water.
What does this demonstration indicate?
Answers
Answer:
Burning sugar results in a chemical reaction
Explanation:
Flammability, odor, and density are just a few examples of characteristic properties of a substance. A chemical reaction occurs when molecules interact with one another and the molecules change. For example burning sugar results in a chemical reaction because the properties of cube B changed when it was burned. This change in solubility shows that cube B must be a different substance than cube A because of the chemical reaction that occurred when cube B was burned.

Which of the following converts food into energy for the cell?
Vaculoe
Cytoplasms
Mitochondria
Cell Membrane
Answers
Mitochondria converts food into energy for the cell.
Mitochondria convert food into energy for the cell. Option 3 is correct.
Mitochondria are often referred to as the "powerhouses" of the cell because their primary function is to generate energy in the form of adenosine triphosphate (ATP) through a process called cellular respiration. This process involves the breakdown of glucose and other organic molecules to produce ATP, which is the main energy currency of the cell.
Inside the mitochondria, there are specialized structures called cristae, which increase the surface area available for cellular respiration. The mitochondria have an outer membrane and an inner membrane, with a space called the intermembrane space in between. The inner membrane contains proteins and enzymes involved in the electron transport chain, a key step in ATP production.
During cellular respiration, glucose is broken down through a series of biochemical reactions, such as glycolysis, the citric acid cycle (also known as the Krebs cycle), and the electron transport chain. These reactions occur in the mitochondria, specifically in the matrix (fluid-filled region) and on the inner mitochondrial membrane. Through these processes, the energy stored in glucose is gradually released, and ATP is synthesized.
The ATP produced by the mitochondria is then used by the cell to power various cellular activities, including metabolism, active transport, muscle contraction, and synthesis of macromolecules. Without functional mitochondria, cells would not be able to efficiently convert food into energy, and vital cellular processes would be impaired.
