Answer:

Option A is the correct one.

Explanation:

limnetic zone

The limnetic zone is the most photosynthetically-active zone of a lake since it is the primary habitat for planktonic species. Because phytoplankton populations are densest here, it is the zone most heavily responsible for oxygen production within the aquatic ecosystem

Answer:

No.

Explanation:

No, elements of xylem in a vascular bundle are not lesser than those of phloem because of the division of xylem progenitor cells that increases the xylem concentration in vascular bundle. The vascular cambium forms more xylem tissue than phloem due to more division of the xylem progenitor cells. so in the light of this discussion we can say that xylem is more in concentration than phloem in a vascular bundle.

Answer:

Traits are determined by genes, and also they are determined by the interaction with the environment with genes. And remember that genes are the messages in our DNA that define individual characteristics. So the trait is the manifestation of the product of a gene that is coded for by the DNA.

Answer:

All cells have plasma membranes. Can molecules enter and leave the cell? Yes. The plasma membrane (also called the cell membrane), is a lipid barrier where molecule organelles live. The golgi ( a cell organelle) helps move the proteins across the plasma membarane. Proteins cannot move through the plasma membrane barrier by themselves because they are not small enough like water.

Answer:

Explanation:

Chicken contains many different amino acids with different R-groups. In particular, chicken contains a large number of Tryptophan amino acids, which are amino acids that contain the side chain known as “indole”.

The type of food molecules that make up chicken is Proteins. It generally contains about 20% of proteins.

Food molecules are those which give energy to living organisms and contain chemicals that are required for the growth and repair of cells and their functions in the body of living organisms.

Proteins are the polymers of amino acids, which are linked via peptide bonds. The side chains of amino acids are varied from one to another. These side chains provide stability to the amino acid sequence. Mostly, the side chain of tryptophan and arginine gives the makeup to the food molecules of chicken.

Therefore, the type of food molecules that make up chicken is Proteins.

The best model of a guard cell is Water Balloon. Thus, option "C" is  the correct answer.

Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere.

Transpiration is essentially evaporation of water from plant leaves. Transpiration is important because water is needed for photosynthesis and because water cools a plant off.

Thus, option "C" is  the correct answer.

Answer:

Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.

Explanation:

:)

Answer: Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.

. Most of these differences relate back to the fact that, although both are needed for cell replication, mitosis and meiosis have different purposes: mitosis replaces body cells with identical copies, while meiosis creates genetically different sex cells that will be used to create an entirely new organism.

Answer:

The correct answer is ''post-zygotic barrier to reproduction''

Explanation:

Biological barriers prevent the exchange of genes between two or more populations, a postzygotic reproductive barrier reduces the survival or reproduction of hybrid offspring. In hybrid non-viability there is low survival of the hybrid, especially during embryonic stages. On the other hand, the sterility of the hybrid occurs when the fertilized egg develops into a healthy but sterile adult. Segregation of aneuploid gametes during meiosis, different gene associations occur on the chromosomes of the parents.

Explanation:

The resulting particles are called sediments.

Rocks and minerals are disintegrated by agents of weathering such as water, glacial (ice) and wind. When these agents of weathering act on rock and minerals, they break down into small particles. These small pieces of weathered rocks and minerals is what is called sediments.

Sediments are pieces of weathered materials from rocks and minerals which can be carried by agents of erosion and deposited in another location.

Thus, the resulting particles from the breakdown of rocks and minerals are called sediments.

Explanation:

The insect with the pesticide resistance gene reproduces, these insects are more likely to survive pesticide application  hence insects with this trait become more prominent in the population

A pesticide refers to a chemical that is used to control the spread of pests in the farm.

The question is incomplete but I will help you the much I can. We know that organisms that have favorable traits live long enough to reproduce and pass on these favorable traits to the next generation. Therefore, the insect with the pesticide resistance gene reproduces. Because these insects are more likely to survive pesticide application, insects with this trait become more prominent in the population

This looks like an earthquake

Explanation:

There doesn’t seem to be very much water present in the image which would be the cause for the rest of them

Hope this helps

Answer:

Earthquake

Explanation:

First off I wouldn't say landslide because if it was a landslide in more than likely would have cracked the concrete on the floor that the people are standing on and there would be more of a mess than what is show in the picture. Next I wouldn't say tsunami depending on how frequent this disaster was, if it was a tsunami more than likely most of that rubbish would have been soaked with water in other things that were in the water as well and I wouldn't say flood either because once again nothing is soaked with water with in that picture not even the concrete that the people are standing on so I say that the most reasonable answer would be earthquake due to them being know for destroying buildings alot.
