In a population of 1000 individuals, 500 new individuals were born and 200 individuals died over the course of 1 year. Which equ
blagie [28]

(Initial individuals + newborn individuals) - dead individuals = total individuals

Growth rate = (total individuals/initial individuals) * 100

Population growth rate = new percentage minus 100%

Calculations

(1000 + 500) - 200 = 1500 - 200 = 1300

Growth rate = (1300/ 1000) * 100

= 1.3 * 100

= 130%

Population growth rate = 130% - 100%

= 30% per year if it is uniform

Lisa [10]

Answer:

a The volume of the liquid should be measured before it is heated.

Explanation:

A student would like to determine how heating a liquid changes its volume. The student hypothesizes that the liquid will increase in volume. The following list shows the steps taken by the student in order to test the hypothesis.

Select the liquid to test.

Place the liquid in a sealed container.

Use a Bunsen burner to heat the liquid by 10°C.

Measure the volume of the liquid.

Record the results.

What is wrong with how the student conducted the investigation?

a The volume of the liquid should be measured before it is heated.

b The hypothesis was not valid because it is impossible for liquids to change in volume.

c The student should have increased the temperature of the liquid by more than 10ºC.

d The length of time it took for the liquid to be heated should be measured.

The answer is A i.e The volume of the liquid should be measured before it is heated. I think this is surely right!!

multigene families include two or more nearly identical genes or genes sharing nearly identical sequences. a classical example i
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.
