What is a specialized species

1 answer:

5 0

A generalist species is able to thrive in a wide variety of environmental conditions and can make use of a variety of different resources. A specialist species can thrive only in a narrow range of environmental conditions or has a limited diet. Most organisms do not all fit neatly into either group, however.

A planet is inhabited by creatures that reproduce with the same hereditary patterns seen in humans. Three phenotypic characters

Zigmanuir [339]

Answer:

For the first experiment, the recombination frequency is shown below. This experiment comprises the cross between the Tall and the Antennae.

Tall-antennae - 46% - Expected

Dwarf-no antennae - 42% - Expected

Dwarf-antennae - 7% - Recombinant

Tall-no antennae - 5% - Recombinant

Total = 100%

For the recombinants, the recombination frequency is:

= 7 + 5 = 12%

Thus, the recombination frequency between the T and A genes is 12%.

For the second experiment, the cross takes place between the heterozygous antennae and the upturned snout. The results are shown below:

Antennae-upturned snout - 47% - Expected

No antennae-downward snout - 48 % - Expected

Antennae-downward snout - 2% - Recombinant

No antennae-upturned snout - 3% - Recombinant

Total = 100%

The recombinant frequency is = 2 + 3 = 5%

Thus, the recombination frequency between the A and S genes is 5%.

The lysogenic cycle is beneficial to the reproduction of a bacteriophage because ___________________.

aleksandrvk [35]

The answer is D- it allows the phage DNA to be replicated during bacterial replication

Bacteriophage can use two different cycles: the lysogenic cycle or lytic cycle.

the lysogenic cycle is a method by which a bacteriophage can replicate its DNA using a bacteria cell. In this cycle the DNA is only replicated, not translated into proteins so the bacteria won't be killed.

The lungs deliver a regular supply of oxygen to the blood, which is in turn circulated to most all the cells of the body. At the

jok3333 [9.3K]

Answer:

The correct answer would be - oxygen will passively diffuse into the cells.

Explanation:

As the oxygen molecules are very small and has no polarity or no charge they show the passive diffusion through the plasma membrane from the higher concentration to lower concentration inside the cell.

In the lungs the oxygen diffuses out the air sacs into the blood as the air sacs of lungs have higher concentration of oxygen than the blood stream and as the various cells perform the aerobic cellular respiration the concentration of the oxygen inside of the cell become low to the blood so oxygen diffuses into cells.

Thus, the correct answer is - oxygen will passively diffuse into the cells.

This functional group is a nitrogen with two hydrogens attached to it. It is found in proteins and functions as a base.

Evgesh-ka [11]

Amino group

The term "amino acid" refers to an amino acid with an amino group immediately linked to the -carbon. These contain the secondary amines proline and hydroxyproline. They were previously frequently referred to as amino acids, which is incorrect because they lack the imine grouping HN=C. The archaic phrase is still used often.
The building blocks of proteins are amino acids, which are the chemical compounds that come together to make proteins. These biomolecules are essential for human growth and development and are engaged in a number of biological and chemical processes in the body. In nature, there are around 300 amino acids.
