Atoms are the basic building blocks of ordinary matter. Atoms can join together to form molecules, which in turn form most of the objects around you. Atoms are composed of particles called protons, electrons and neutrons.

A tall plant crossed with a short one produced offspring, of which about half are tall and half are short. What are the genotype

stellarik [79]

Answer:

Rr x rr

Explanation:

Let's say

RR is a tall plant.

Rr is tall

& rr is a small plant

The only genotypes you can get to make two tall and two short is if you use a hetero pair and a same ressesive (rr) genes.

11. If you wanted to obtain 100% roan calves, what would the parents' genotypes need to be?

belka [17]

If you wanted to obtain 100% roan calves, then it si required to cross parents who are homo-zygous (pure lines) for the genes associated with this trait.

<h3>What is a homo-zygous individual?</h3>

A homo-zygous is an individual who has the same gene variants or alleles for a given gene locus.

Conversely, a heterozygous is an individual who has different gene variants or alleles for a given gene locus.

In breeding, pure lines (or purebred) are homo-zygous individuals that may be crossed to obtain the desired trait in the descendence.

Milankovitch cycles describe the effects of changes as a result of climate change. There are three Milankovitch cycles:about Earth's Eccentricity (the shape of the Earth's orbit around the Sun), Axial tilt (the inclination of the Earth's axis in relation to its plane of orbit around the Sun) and precession (the Earth's slow wobble as it spins on axis).
According to this, Milankovitch's cycles <span>are changes in earth's rotation and orbit around the sun that may trigger climate variation. (B).</span>

Explain how environmental agents such as chemicals and radiation cause cancer.

Paul [167]

Chemical (mutagens) usually either mimic the structure of nucleotides and are inserted in DNA or either cause chemical changes (such as alkylation) in nucleotides hence causing mismatching during replication. Radiation, on the other hand, (due to its high energy) causes double-strand breaks in DNA causing an increased likelihood of mutations during the repair of the DNA by cell mechanisms.
