How does climate determine the organisms that live in a biome
maria [59]
<span>Different organisms thrive in different biomes. The reason for this is that different organisms have different needs for survival. Climate and nutrition play the biggest part in determining if an organism will live in a biome. If the climate is unfavourable, the organism will either die or simply move to a different flora. The other option is that it could adapt to the conditions of it's current biome but this often takes a much longer time.</span>

What was the purpose of Mendel's experiments with dihybrid crosses?
yuradex [85]

Answer:  The correct option is B. To determine if one trait could affect the inheritance of other trait.

The dihybrid cross is a cross between the two parents who have difference in two pairs of the alleles.

In the experiment of the dihybrid cross, during the first meiotic division the homologous pair of the chromosomes aligned randomly before getting separated from each other. The separation of the chromosomes leads to independent assortment. The four cells which are formed during the second meiotic division are developed into the haploid gametes.

The relationship data of the dominance for each trait between the alleles was available with Mendel. The purpose of the dihybrid cross was to determine the type of relationship that existed between the pair of alleles.

The result of the experiment of the dihybrid cross was the law of independent assortment according to which the formation of gametes the segregation of alleles of both the pairs of alleles are independent of each other.

The volume of a certain gas is 29.3 liters at STP. What would be the volume of the same gas at 1.39 atmospheres and -23.00C? (R=
Andrew [12]

Answer:

19.32L

Explanation:

Given parameters:

Volume of the gas at STP = 29.3liters;

      Using this information first, let us find the number of moles of the gas.

                  Number of moles = \frac{volume of gas}{22.4}

With the number of moles, we can further solve this problem;

                 Number of moles  = \frac{29.3}{22.4}   = 1.31 moles

More parameters;

Pressure on gas  = 1.39atm

temperature  = -23°C  = -23 + 273  = 250K

Unknown:

Volume of gas  = ?

Solution:

The ideal gas equation is the perfect fix to solve this problem.

It is mathematically expressed as;

              Pv  = nRT

where P is the pressure

           v is the volume

           R is the gas constant

            n is the number of moles

            T is the temperature

     Input the parameters;

             1.39 x V  = 1.31 x 0.082 x 250

                     V  = 19.32L

erastova [34]

Answer:

In immunology, an antigen is a molecule or molecular structure, such as may be present on the outside of a pathogen, that can be bound by an antigen-specific antibody or B-cell antigen receptor. The presence of antigens in the body normally triggers an immune response.
