Heterozygous dominant is the genotype of the sweet pea. thus option A is correct.

The genetic foundation of a certain trait is called an organism's genotype. While an organism's phenotype refers to its outward appearance.

When an organism has two copies of the same dominant allele, it is said to be homozygous dominant.

The identical recessive allele is present in two copies in a homozygous recessive organism.

An organism is said to be heterozygous if it possesses both the dominant and recessive alleles of a gene.

Humoral immunity protects the body against extracellular pathogens and Cell mediated immunity protects the body from intracellular pathogens .

Humoral immunity: It is the process adaptive immunity manifested by the production of antibodies by B lymphocytes. It develops the bone marrow. B cells may be trigged to proliferate into plasma cells.

Cell mediated immunity:  Cell mediated immunity is an immune response that does not involve antibodies but rather involves the activation of macrophages and NK cells.

Humoral immunity and cell mediated immunity works together with assistance from helper T cells, B cells.

Glaciers grow smaller, causing sea level to rise when Earth's global temperature is lower. Thus, the correct option is C.

Sea level lowers during cold climate periods, known as glacial epochs or ice ages, due to a shift in the global hydrologic cycle, in which water evaporates from the oceans and is stored on the continents as massive ice sheets, extended ice caps, ice fields, and mountain glaciers. At the last glacial maximum, some 20,000 years ago, global sea level was about 125 meters lower than it is today.

Because the melting North American, Eurasian, South American, Greenland, and Antarctic ice sheets returned their stored water to the world's oceans as the climate warmed, sea level rose. Sea level is at its highest during the warmest eras, known as interglacial epochs.

We are currently living in the most recent interglacial, which began around 10,000 years ago and is referred to by geologists as the Holocene Epoch. Sea levels were about 3 to 20 meters higher than they are now during several previous interglacials.

Answer:

When minute samples of DNA need to be genetically analyzed for identification purposes, which test can be effectively used? Fluorescent dye can be used as a label to trace antibody-antigen reactions in an ELISA assay

DNA is the genetic material that is the unit of inheritance. Small DNA samples can be increased in amount by the technique called PCR. Thus, option D is correct.

Polymerase chain reaction (PCR) is the technique used in biotechnology to quantitatively increase the amount of genetic material. It has been known to create billions and millions of copies of the sample.

The small DNA sample can be amplified by the process of PCR which involves the production of the DNA sample by the polymerase and primers to add the bases to the strand.

The DNA undergoes thermal cycling where the temperature of the system first increases in denaturation followed by a drop in temperature in annealing and lastly again a rise of temperature in extension.

Therefore, the PCR technique can increase the amount of small DNA samples.

Answer:

Climate has generally changed from warm to cool globally mostly because of glaciers. Our climate can be changed in the future by the glaciers, also. Think about it this way, glaciers in the south pole melt, and the sea levels rise. Wind currents shift the glaciers and ice shelves, so they break. This will cause the world to overheat, and sea levels to rise. That's how our climate has and will change over time.

This is called a volcanic winter.

Explanation:

The reason why it is called a volcanic winter, is because in winter, it is colder than the other seasons, but, here's the difference. A volcanic winter is because sunlight is blocked, and a regular winter is when the earth is tilted in a place where the area is not being shined on by the sun.

Global winds are winds that appear in belts that go all around the world. Like local winds, global winds are driven by unequal heating of the atmosphere. Since global winds blow west to east, it helps humans travel west to east.

Global wind belts and calm regions have an effect on, is that the berg winds blow from the east and die out as they are available close to the equator.

The westerlies blow from the west and move storms across u. s. The easterlies blow from the east and they cause stormy weather to occur once cold air forms this belt meets heat air of the westerlies.

C: Cuscuta is a parasite .

Explanation:

Mushrooms are a part of the fungi domain meaning that it is a decomposer.  I'm not too sure whether it means stem body cells or a stem in a plant. Either way both are not parasites. Cuscuta is a plant that does not have chlorophyll (they can't carry out photosynthesis) and since this plant cannot make its own food, it feeds off a host plant that can make food. An organism that needs a host to survive is called a parasite. Haustoria is a part of some parasites however it itself is not one. And finally Rhizobium is a bacteria that converts Nitrogen into ammonia which helps plants.

Reduce the amount of pollutants that enter wetlands  best describes something these laws were intended to do. Thus, the correct option is A.

The CWA made it illegal to dump any pollutant into navigable waters from a point source unless a permit was obtained:

The Clean Water Act establishes the basic structure for regulating pollutant discharges into US waters as well as regulating surface water quality standards. The Federal Water Pollution Control Act, which served as the foundation for the CWA, was enacted in 1948, but it was significantly reorganized and expanded in 1972. With modifications in 1972, the Act's common name became "Clean Water Act."

Answer:

Nitrogen Fixation

Explanation:

Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation.

Plants must use nitrates in a form of nitrogen, which is needed to make proteins for healthy growth.

Nitrate plays a very important role in our ecosystem such that due to presence of nitrogen plants grow fastly and produce fruits of  bigger size  flowers too.

Plants absorb nitrates from  water through their roots without nitrates, the amount of chlorophyll in leaves reduces.

Nitrate is a common inorganic ion found in plants which is  required for proper growth and development of the plant and growers include the percentage of nitrates in their nutrient requirement to starts plant growth. Plants acquire nitrate through root intake from the soil and water around them.

Hence due to decreasing percentage of nitrogen plants are getting yellowed it means it produces smaller fruit.

In modern era farmers add nitrogen containing fertilizers which produce large amount of grains, foods and fruits which is also diseases free.

Therefore,Plants must use nitrates in a form of nitrogen, which is needed to make proteins for healthy growth.
