Fossil evidence indicates that the first organisms on Earth were single-called prokaryotes. The first eukaryotes are believed to have formed from these prokaryotes. How does the endosymbiotic theory explain the development of the first eukaryotic organisms?.
The study of fossils shows that the eukaryotic cells have been evolved from the prokaryotic cells. The endosymbiotic theory has been used to study the evolution of eukaryotic cells.
The endosymbiotic theory states that:
Endosymbiotic theory is also referred to as the theory of symbiogenesis. The theory explains the evolution of eukaryotic cells from prokaryotic cells. The theory explains the presence of chloroplasts and mitochondria, and how these organelles form the eukaryotic cells. The theory explains the origin of mitochondria in animal cells and chloroplasts in plant cells.
Thus, the endosymbiotic theory defines the development of eukaryotic cells from the prokaryotic cells.

how does carbon move through the system when there is light
Answer:
Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them.
Explanation:
The sun takes an integral role in the photosynthesis stage of the Carbon Cycle. Photosynthesis refers to the process by which plants take in carbon dioxide and water (the products of respiration), and convert it to oxygen, powered by the energy of the sun.

When a substance changes from a gas into a liquid due to a change in temperature, melting occurs, which is a physical change.
When a substance changes from a solid into a liquid due to an increase in temperature, it is a physical change.
When a substance changes from a gas into a liquid due to a decrease in temperature, the substance cools down and condenses, which is a phase change.
When a substance changes from a liquid into a gas due to a decrease in temperature, the substance evaporates and cools down, which is a phase change.

Which is another way to describe a gene?
A: a sequence of three base pairs
B: a unit of inheritance that transmits information
C: a short segment of information that is translated and taken out of the nucleus
Answer:-B: a unit of inheritance that transmits information
Explanation:-A gene is the basic unit of heredity that occupies a specific position on a chromosome. Each is composed of linearly arranged nucleotides.
In another way, a gene may be described as a unit of inheritance that transmits information. Thus, the correct option is B.
What is a Gene?A gene may be defined as a stretch of a segment that is present in the chromosome and helps to determine a characteristic.
Genes are present in the chromosomes of an organism. Genes carry out the instructions to construct molecules called proteins which induce specialized operations and build up the structure of living organisms.
Therefore, the correct option for this question is B.

A elephant cell has 20 chromosomes. how many chromosomes will the cell have just before mitosis begins in the elephant cell?
The elephant cell will have 20 chromosomes.
Cells undergo interphase before getting to the mitotic phase. At the S phase of the interphase, the amount of DNA in the cell is double by replication. However, the number of chromosomes remains intact.
Thus, the cell gets to the mitotic phase with the same number of chromosomes that is usually present in normal vegetative cells of the animal.

All cells come from other cells. New cells are created by a process called cell division. To start cell division, a cell grows bigger and makes copies of the parts inside it. Then, the cell and its parts separate into two new cells. Each new cell contains the same types of cell parts as the original cell. Later, each of these cells may divide again to form more cells. When a multicellular organism's cells divide, the organism can grow. Each resulting cell is part of that organism. When a unicellular organism divides, each resulting cell is a separate unicellular organism. The micrographs below show cells from two different organisms: Giardia, a unicellular protist, and banana, a multicellular plant. Giardia cells in a banana Which of the following statements are true? Select all that apply.?
a. A rose bush cell can divide to form two rose bushes
b. If the bacterium divides, it will become a multicellular organism
c. When a rose bush cell divides, it copies its parts then divides into two cells
d. The bacterium was formed when another bacterium divided
Answer:
c. When a rose bush cell divides, it copies its parts then divides into two cells and
d. The bacterium was formed when another bacterium divided
Explanation:
C is correct because the cells inside are part of a larger being (the rose bush), when they divide they are simply creating more cells (hence making the rose bush grow).
D is correct because bacterium are unicellular organisms, meaning they are themselves single cells that are organisms, unlike the rose bush consisting of many cells.

Answer:The behavior of the both liquid and gas will be different in some aspect and same in the other, lets see how:
Explanation:
As we have studies that liquids donot have a specific shape but do have a specific volume. So when the liquid will be transferred from small to large container, it will adapt the shape of new container but its volume will stay same as it was in old container.
On the other hand, about gases, we know that they donot have specific shapes and the volume is also not definite and depends on the shape of container. Therefore, the gas atoms will freely move in the container and the volume will be changes in large container.
