One parent reproduction occur when the leaf is used for growing a plant because it is involved only one parent.

<h3>What is cutting?</h3>

Cutting is an one parent reproduction in which vegetative parts are used to grow plants. There is no use of seed in it, such type of reproduction is called single parent reproduction.

So we can conclude that single parent reproduction occur when the leaf is used for growing a plant because it is involved only one parent.

when changes in a protein appear to accumulate at a constant rate over time is called option (c) i.e, Molecular clock.

<h3>What does molecular clock mean?</h3>

The term "molecular clock" refers to a method that estimates the time in prehistory when two or more life forms diverged by analyzing the mutation rate of biomolecules. Typically, nucleotide sequences for DNA, RNA, or amino acid sequences for proteins serve as the biomolecular data for these calculations.

Hedges, a biology professor at Penn State, claims that the molecular clock counts the mutations that accumulate through time in the gene sequences of various species rather than counting seconds, minutes, and hours.

Mutation and recombination, the two fundamental biological processes that give rise to all heritable variations, are the foundation of molecular clocks. Mutations are modifications to the genetic code of DNA, for as when the nucleotide Guanine (G) turns to Thymine (T).

What is the difference between mechanical digestion and chemical digestion?
Bad White [126]

Answer:

So, Mechanical and Chemical Digestion is the way of breaking down foods in the body. The difference between Mechanical and Chemical Digestion is, Mechanical Digestion involves the body's movement to make the food smaller and Chemical Digestion involves enzymes to break the food down.

Explanation:

Since Mechanical Digestion involves moving around to break the food down, you would get up and walk around a little to burn it to make it work and Chemical Digestion is just using the natural enzymes in the body to break food down.

Drag each tile to the correct location.
Ivahew [28]

Answer:

Mitosis and meiosis are similar at the level of writing, and possess a very close mechanism; however, they do not achieve the same result!

Mitosis corresponds to a single "asexual" cell division of somatic cells (almost all cells in the body), and clones two daughter cells from a mother cell, which will be identical, and inherit exactly the same heritage genetic, indeed these two daughter cells will each have an identical karyotype (same chromosomes) and an identical genotype (same alleles) to that of the mother cell.

Meiosis corresponds to two successive "sexual" cell divisions affecting only germ cells; starting from a diploid cell (chromosomes present in pairs), meiosis leads to the formation of four gametes (haploid sexual cells, spermatozoa or oocytes) (a single copy of the chromosomes). Then, during fertilization, two gametes (each from meiosis, in the male and female) come together to form a zygote, in which diploidy will be restored.

The right answers are:

create two identical cells ==> mitosis

create four non-identical cells ==> meiosis

create haploid cells ==> meiosis

creates diploid cells ==> mitosis

occurs in all cels other tha gametes ==> mitosis

occurs in all cells related to sexual reproduction ==> meiosis
