Plants absorb carbon dioxide, water and sunlight to make their own food, grow and release oxygen through photosynthesis. They're a huge part in keeping our air clean. The carbon becomes part of the plant.
If the question was about which part of the body it was discovered in it was in the blood cells
Answer: The correct answers are as follows:
1. During cytokinesis, THE CELL MEMBRANE PINCHES IN TO FORM TWO NEW CELLS.
Cytokinesis is the physical process of cell division, it divides the cytoplasmic content of the parental cell into two new daughter cells. Cytokinesis takes place in both mitosis and meosis.
2. The correct order of the phases of mitosis are as follows: PROPHASE, METAPHASE, ANAPHASE AND TELOPHASE.
Mitosis is the process of cell division by which a cell is divided into two new cells. The process occurs in four basic stages and result in the formation of two new cells.
3. The following terms are related to sexual reproduction: MATING SYSTEM, GAMETE FORMATION AND AMPLEXUS.
Amplexus refers to the mating positions of frogs and toads during sexual reproduction. Mating system refers to the number of mating partners that an animal has during the mating period. Gamete formation is the process by which sex cells are made and it occurs in both male and female animals.
4. As a cell is preparing to divide by mitosis, the DNA MUST BE COPIED.
When a cell is getting ready to divide by mitosis, it will undergo a stage called interphase, during which the cell prepare for cell division. During interphase, the cell undergo some process and these include the copying of the DNA. The cell copies its DNA so that it has two copies of each strand.
Explanation:
Some people have freckles, and some people do not have freckles. If a child has freckles, at least one parent has freckles.
Freckles are determined by two genes instead of by one. If Mendel had crossed a true breeding dominant plant with a true breeding recessive plant, in which of the three generations is the recessive trait visible.
Freckles are not determined by DNA. There are two alleles for freckles. There is no dominant allele for freckles. Freckles are determined by two genes instead of by one. F1 generation .P generation, F1 generation and F2 generation, P generation and F2 generation.
Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis during replication as the DNA polymerases cannot begin the synthesis of the new strand, they only extend it after primase begins it and primase produces RNA molecules, the enzyme can be said to be a type of RNA polymerase.
Therefore, Some people have freckles, and some people do not have freckles. If a child has freckles, at least one parent has freckles.

Part 1.
The correct answer is option 2.There are two alleles for freckles.
According to the condition of the occurrence of the freckles, it can be concluded that the freckle is an autosomal dominant condition. The freckle can only be inherited, if there is at least one dominant allele in any of the parent. If both the individuals are heterozygous for the trait, they can produce an offspring without freckle by passing down the recessive alleles to the progeny. So, the freckles are controlled by two alleles, which can be either dominant or recessive.
Part 2.
The correct answer is option 4. P generation and F2 generation.
In this case, it is given that true bred homozygous recessive plant is crossed with true bred homozygous dominant plant. The true bred recessive plant always shows the recessive phenotype. When true bred homozygous recessive plant is crossed with true bred homozygous dominant plant, the F1 generation would produce all the heterozygous individual and exhibit dominant phenotype. When the F1 generation is self crossed, it result in 75% dominant phenotype and 25% recessive phenotype.
A possible cross for this case is given in the picture.
