finlep [7]3 years ago

Answer:

1.) Mutation or outside effect

2.) The DNA copies itself

Explanation:

1.) Mutations can occur when a body is exposed to high amounts of radiation or other harmful chemicals, thus changing the DNA.

2.) In order for our bodies to grow, cells must divide and make new cells. Each time a cell makes new cells, the DNA has to copy itself for the new cell. This process is called “replication.”

hope this helped!

let me know in the comments if this was right and/or wrong!

(p.s) mark me as brainliest if you feel my answer was good enough :))

Alleles can be described as 1. dominant 11. recessive III. codominant IV. partially dominant V. incompletely dominant O A. I, II
joja [24]

Answer:

A. I, II, III, and V only

Explanation:

In genetics, an allele refers to the specific form of a gene, which encodes traits. These alleles are usually in pairs in a diploid organism i.e. an organism with two sets of chromosomes. According to Gregor Mendel,

- An allele can either be DOMINANT when the allele masks the phenotypic expression of its allelic pair while the allele that is masked is said to be RECESSIVE.

- Two alleles can also be CO-DOMINANT when the two alleles are neither dominant or recessive over one another but are simultaneously expressed in that particular gene.

- Alleles can also be INCOMPLETELY DOMINANT when one allele is not completely dominant over the other, hence, forms a third intermediate phenotype when in combination with the second allele i.e. in an heterozygous state.

Based on this, an allele can be dominant (I), recessive (II), codominant (III), and incompletely dominant (V).

Scientists say that photosynthesis and cellular respiration are reciprocal processes. Why
ANTONII [103]

Cellular respiration and photosynthesis are essentially opposite processes. Photosynthesis is the process by which organisms make high-energy compounds -- the sugar glucose in particular -- through the chemical "reduction" of carbon dioxide (CO2). Cellular respiration, on the other hand, involves the breakdown of glucose and other compounds through chemical "oxidation." Photosynthesis consumes CO2 and produces oxygen. Cellular respiration consumes oxygen and produces CO2.
