Which chamber of the heart pumps deoxygenated blood to the lungs?

Biology

Lunna [17]3 years ago

The heart consists of four chambers in which blood flows. Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium.

vova2212 [387]

Identical and obviously duplicated gene sequences have gotten from one chromosome to another by chromosomal translocation.

In terms of genetics, a translocation takes place when chromosome fragments and the (often two) fragmented portions reassociate with other chromosomes. For the diagnosis of several genetic diseases and syndromes, the finding of chromosomal translocations can be crucial.

Multigene families are groups of related or identical genes that have developed by gene duplication. It is thought that a single ancestral gene was duplicated and varied to create multigene families. The multigene families that code for actins, hemoglobins, immunoglobulins, tubulins, interferons, histones, etc. are a few examples.

Calculate the acceleration of a ball has been dropped from the roof. It accelerates from 10 m/s to 30 m/s in 2 sec. 1 point 15 m
Andre45 [30]

Answer:

10 m/s/s or m/s²

Explanation:

Acceleration can be calculated by using the formula;

a = v - u/t

Where;

a = acceleration (m/s²)

v = final velocity (m/s)

u = initial velocity (m/s)

t = time (s)

In other terms, acceleration (a) can be represented as ∆V/t.

According to this question, a ball accelerates from 10 m/s (u) to 30 m/s (v) in 2 seconds. Hence, the acceleration of the ball is as follows:

a = 30 - 10/2

a = 20/2

a = 10m/s².
