irinina [24]

Answer;

-Suspension

Cells not dissolve in blood but they form a suspension because they do not settle out of the blood either

Explanation;

-Blood is a solution of salts, glucose, urea and a few other small compounds. It's a colloid of plasma proteins, including albumin, transport proteins and antibodies. It's also a suspension of blood cells and platelets.

-Suspensions and colloids are two common types of mixtures whose properties are in many ways intermediate between those of true solutions and heterogeneous mixtures. A suspension is a heterogeneous mixture of particles with diameters of about 1 µm (1000 nm) that are distributed throughout a second phase.

-Common suspensions include paint, blood, and hot chocolate, which are solid particles in a liquid, and aerosol sprays, which are liquid particles in a gas.

Ostrovityanka [42]

Answer:

R = 0 and no population growth.

Explanation:

Birth rate may be defined as the growth of individual per thousand and death rate determines the death of individual per thousand in a year. The birth and death changes the population dynamics.

The growth rate depends on both the factors that are birth rate and death rate. Here, the birth rate is balanced or equal that replace the offspring father. The change in the population growth is same and the birth and replacement almost cancel out each other. In this case, the birth rate is zero and population do not grow.

Thus, the answer is  R = 0 and no population growth.
