Answer:

600 kcal

Explanation:

In an ecosystem, energy is transferred from one organism in a trophic level to another organism in another trophic level. Organisms called PRODUCERS are capable of deriving energy from the sun. However, when fed upon by PRIMARY CONSUMERS, only about 10% of the energy is transferred to them because most of the energy (90%) is lost as heat.

Hence, in this case where the producers had 6,000 kcal of energy, 10% i.e. 10/100 of 6000 = 600 kcal of energy will be transferred to the primary consumers.

An individual that is homozygous dominant for type B blood and little finger shape mates with an individual that is heterozygous

gregori [183]

Answer:

Let "L" be the dominant allele for little finger shape and "l" be the recessive allele for the same.

It is given that a person is homozygous dominant for blood group B and little finger shape. Hence, the genotype would be $I^BI^B$ LL

The other person is heterozygous for blood group A and homozygous recessive for little finger shape. Hence, the genotype would be $I^Aill$

The type of gametes formed by the first parent would be $I^BL$ only.

The type of gametes formed by second parent would be $I^Al$ and il.

The cross is shown in the attached figure.

According to the cross, we get two phenotype:

offspring with blood group AB and dominant little finger shape, and
offspring with blood group group B and dominant little finger shape.
They are present in 4 : 4 = 1 : 1

According to the cross, we get two genotype:

$I^AI^BLl$
$I^BiLl$
They are also present in 4 : 4 = 1 : 1.

Compare ionic solids and liquids

Lapatulllka [165]

At room temperature and normal atmospheric pressure, covalent compounds may exist as a solid, a liquid, or a gas, whereas ionic compounds exist only as solids, Ionic compounds exist in stable crystalline structures. Therefore, they have higher melting and boiling points compared to covalent compounds.

Which of the following does not indicate microbe involvement in energy and nutrient flow? Select one: a. Thermal hot springs war

Aneli [31]

<h2>Correct Answer is (b)</h2>

Explanation:

(b) is right Answer.

An Greenhouse gas is any vaporous compound in the environment that is equipped for engrossing infrared radiation, consequently catching and holding heat in the climate.
The warmth in the environment, ozone harming substances are liable for the nursery impact, which eventually prompts an Earth-wide temperature boost.
Methanogenesis is known as when the development of methane by the microorganism. Life forms fit for delivering methane have been distinguished uniquely from the space Archaea, a gathering phylogenetically unmistakable from the two eukaryotes and microscopic organisms, albeit many live in close relationship with anaerobic microbes.
Animals and cultivating, rot in landfills, spillage from the oil and gas industry.
Since 1750, the measure of methane in the climate has multiplied due to human action.
The oil and gas industry is the top donor, making 33% of all methane emanations.
