What are zooplanktons?

Zooplankton is a small floating or weakly swimming organisms that drift with water currents and, with phytoplankton, make up the planktonic food supply upon which almost all oceanic organisms are ultimately dependent.

Ocean acidification may affect zooplankton directly by decreasing in pH, as well as indirectly by trophic pathways, where changes in carbon availability or pH effects on primary producers may cascade up the food web thereby altering ecosystem functioning and community composition.

Explain how nitrate ions help plants to grow.

Answers

Answer:

Explanation:

Both nitrate ions and ammonium ions can be taken up by plants (some prefer one to the other). These ions provide nitrogen for the plant to make its own amino acids for protein synthesis. Except in very high nitrogen soils, the addition of extra nitrate will stimulate plant growth.

Nitrogen is an essential macronutrient that is a component of many essential molecules, such as amino acids, proteins, nucleic acids, and chlorophyll.

What are the roles of nitrate in the growth of plants?

Nitrate ions are essential nutrients for plant growth and development. Nitrogen is the fourth most abundant element in plants and is crucial for the growth of leaves, stems, and roots.

Plants require nitrogen in the form of nitrate because it is the most oxidized. It is an easily available form of nitrogen for plants to take up from the soil. Nitrate is absorbed by plants through their roots and transported to the plant cells, where it is used to synthesize amino acids, proteins, and other essential molecules.

Nitrate plays a crucial role in the process of photosynthesis, which is the process by which plants convert sunlight into energy.

A. heat release
B. gas exchange
C. carbohydrate absorption
D. osmotic pressure regulation

Answers

Answer:

B. Gas exchange

Explanation:

because the lungs bring air into your body, it needs a way to transfer the oxygen into your blood stream.

Luckily for us, our lungs have porous linings, which will help the oxygen go directly into our blood stream.

The porous structure of the  blood capillaries and lung tissue allow the them to exchange gas

The porous structure of the lungs allow to exchange gas from the gas in the blood. Blood capillaries are tiny blood vessels in the body.

The gas in the blood was collected from the tissue from the body parts which is made possible because of the porous lining of the blood capillaries.

Therefore, the porous structure of the  blood capillaries and lung tissue allow the them to exchange gas.

Answers

Answer:

Energy

Explanation:

Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy (ΔH < 0). In the lab, exothermic reactions produce heat or may even be explosive.

Explanation:

all plant bodies(root,stem and leaf) are externally covered by epidermis but why woody plant is covered by barks​

Answers

Answer:

Bark comprises all the tissues surrounding the xylem in woody plants. Broadly, bark includes an inner and mostly living region and an outer, dead one. Of all plant structures, bark has the most complex anatomical structure and ontogenetic origin involving two (and often three) different meristems.

As to why, the bark adds layers to the inside ring of the vascular cambium, the outside is pushed outward. The cells die off, and the fibrous matrix of cellulose and lignin molecules remain. This hard structure forms the bark, and protects the tree or plant from many forms of damage.

Using the allele symbols in the table, identify the genotype of a guinea pig that is recessive for hair length, heterozygous for hair color, and homzygous dominant for hair texture.

Answers

Answer:

Hair length: hh

Hair color: Bb

Hair Texture: RR

Explanation:

In order for the recessive gene to show for hair length, two of the same alleles must be present, so, in this case, hh.

The question states "heterozygous for hair color." This tells you that the genotype will be Bb. Heterozygous means two of the different alleles. This is different from homzygous.

The question states "homzygous dominant for hair texture." This tells you that it will contain two of the same alleles. The question also tells you that it is homzygous dominant, which means there will be two of the same dominant alleles, so, RR.
