The answer is immigration rate minus emigration rate.

Emigration is a movement of organisms from the region of settle. So, when organisms leave a population, they emigrate.

Immigration is the opposite process of the emigration in which organism move to some area.

Population change depends on several factors: birth, death, immigration and emigration. If population size is increased, then the death rate must be less than the birth rate. Also, emigration rate must be less than immigration rate. So, to increase population it is necessary for birth and immigration to be higher than death and emigration.

In hamsters, we can examine the genes for coat color and eye color which are linked:B = brown coat, b = white coat, G = green ey

Inessa [10]

Answer:

10.2 cM

Explanation:

Given,

pure breeding parent 1 : BBgg = brown coat and pink eyes

pure breeding parent 2 : bbGG = white coat and green eyes

BBGG X bbgg = F1 = BbGg ( All are brown with green eyes )

When F1 progeny is test crossed with white coat and pink eyes hamster:

BbGg X BbGg = F2 =

brown, pink eyes = 99 = parental

white, green eyes = 103 = parental

brown, green eyes = 12 = recombinant

white, pink eyes = 11 = recombinant

Recombination frequency =

(total number of recombinants / total progeny ) * 100

= [( 11 + 12 ) / ( 99 + 103 + 12 + 11 )] * 100 = (23/225)*100 = 0.102 * 100 = 10.2 %

1 % recombination frequency = 1 cM distance between genes

Hence, the distance between B and G gene is 10.2 cM

what percentage is the tonicity of the medically administered intravenous solutions? what would happen if the tonicity gets lowe

Sunny_sXe [5.5K]

Answer:

<h2>The Infusion Nurses Society (INS) classifies a solution as isotonic if its tonicity falls within (or near) the normal range for blood serum-between 280 and 300 mOsm/liter. A hypotonic solution has an osmolarity less than 280 mOsm/liter, and a hypertonic solution has an osmolarity greater than 300 mOsm/liter.</h2>

Which statement about Earth's rotation and its revolution is correct?

Allisa [31]

Answer:

It takes Earth longer to revolve around the sun than to rotate on its axis.

Explanation:

The vocabulary can be tricky in this question. It is important to remember that the term revolution refers to something moving around a fixed point. In this case, the earth is the object revolving around sun which is the fixed point in the frame of reference.

Now, the earth rotates at a constant speed around its axis. This is what causes the day/night cycle. The earth itself is spinning, therefore we use the term rotate.
