Answer:

2 (tall) :2 (short) or 1:1.

Explanation:

Mendel is known as the father of genetics. He explains the laws of segregation and the laws of independent assortment by working on the pea plant <em>Pisum sativum.</em>

The height of tall pea plant be T and the short pea plant be t. The cross between heterozygous dominant tall pea plant (Tt ) and short pea plant (tt) is as follows:

Parents           Tt         ×          tt

The progeny obtained from the cross are Tt, tt, Tt and tt.

Two tall pea plants and two short pea plants.

Thus, the phenotype ratio is 1:1.

Why do intraplate earthquakes tend to be less frequent and smaller than earthquakes at plate boundaries?
Inga [223]
Earthquakes on plate boundaries happen more because the plates all move in different directions in a tectonic environment so they collide against each other which makes them more frequent. Earthquakes rarely happen in intra-plate environments but along faults in normally stable interior of the plates. If this doesn't make sense, ask me to reword it for you !

Match each major blood vessel with the correct description
zalisa [80]

The aorta carries oxygen rich blood away from the heart.

The pulmonary artery transports deoxygenated blood from the heart to the lungs.

The inferior vena cava carries deoxygenated blood from the lower body to the heart.

The coronary artery branches from the aorta and provide oxygen to the heart muscles.

Zepler [3.9K]

Answer:

<em>Carolus Linnaeus devised the binomial nomenclature system under which the organisms were named using their Genus name and Species name. </em>The Genus name was written first, forward by the species name. The system of binomial nomenclature allowed for assigning a scientific name to all the organisms so that the conversations between scientists could be made easier. For example, humans have the scientific name<u><em>,</em></u><em> Homo Sapiens</em>, where Homo is the genus name and sapiens is the species name.
