Cell differentiation is an essential process for the overall development, growth, reproduction and longevity of the complex multicellular organisms.

Cell differentiation is the process in which the stem cells become more specialized into different cells. Cell differentiation is an essential process because it creates diversity in life on the planet Earth. It creates diversity within the cells of the body of an organism and allows the cells to create unique structures which fit their individualized functions in that organism.

Cell differentiation is an essential process for the development, growth, reproduction, and longevity of all the complex multicellular organism as it is responsible for the formation and maintenance of different organ systems in an organism.

Direct harvesting can be stopped by making stringent laws and follow them, by maintaining the biosphere reserves and also harvest species in a limited number in an environment.

Direct harvesting can be referred to take a species out of it's natural environment. We need to directly harvest various organisms for resources that support our population growth and maintenance. However, direct harvesting such as overfishing and the use of drift nets has threatened the aquatic biodiversity on a large scale. Likewise, we have also hunted and poached endangered animals to the point of near extinction.

Direct harvesting can be stopped by controlling fishing by making strict laws and apply them. We can also restrict the entry of people in the areas where large population of animals are present as reserve areas.

The proper sequence to represent the development of the follicle in the ovary are:

Ovarian follicles develop with the effects of hormones. The follicular phase bears one or two follicles that become dominant and eventually releases an oocyte by luteinizing hormone stimulation.

Development of follicles is stimulated by follicle stimulation hormone (FSH) production in the pituitary gland. Follicles that ripen result in oestrogen level increase. The sequence of follicle development is Primary follicle, Secondary follicle, Mature follicle, Ovulation and Corpus luteum.

Since they have a greater metabolism, smaller creatures breathe more quickly.

1. In general, the rate of oxygen consumption increases with the increase of temperature. So, here at 30 degree the rate of consumption will be the highest, then at 15 degree, at zero degree it will be ice droplets.

2. The aerobic bacteria present in the water respire in the presence of oxygen. at 0,15 and 30 degree. Here anerobic bacteria can be taken as a control.

So, a culture with medium of aerobic bacteria/yeast can be taken.

It is kept in shaking condition 150-200 rpm and then the temperature is kept at 37 degree.

Bacteria has a doubling time of twenty mins, and yeast has a doubling time of 90mins. So, it is kept at overnight incubation for proper growth of the bacteria. Water droplets are visible at the cap.

At 30 degree the consumption is maximum, then the 15 degree is relatively lower and higher is no consumption at 0 degree where it is frozen.

The oxygen consumption is related to the respiration rate of aerobic bacteria , yeast.

The control group in an experiment to show that the hormone estrogen increases the milk yield of dairy cows is the presence of cows that have not been administered with the addition of this hormone or inhibited in the production of estrogen.

The control group in an experiment is a given group of the sample which is not under treatment, which allows us to make comparisons with the target group.

Therefore, with this data, we can see that the control group does not receive the experimental treatment.

Cell function is often compared to the operation of a factory or city as Nucleus. It should be compared to a neighborhood. Thus, option C is correct.

Centrioles are small, cylindrical cell organelles, present near the nuclei of animal cells. They are involved in formation of spindle fibers at the time of cell division that help in proper separation of chromosomes during cell division. Plant cells do not have centrioles.

Nucleus and ribosomes are present in both animal and plant cells, while cell wall is found only in plant cell. Thus, the organelle in diagram that should be listed under 'animal only' will be 'centriole.'

Therefore, Cell function is often compared to the operation of a factory or city as Nucleus. It should be compared to a neighborhood. Thus, option C is correct.

Answer:

A genetic cross involves two parents for a specific trait, such as the hair trait. The gene has variations called alleles. In one gene, one allele is dominant over the other. The complete dominant allele can be found in both purebred and heterozygous forms and suppresses the recessive character. Here, the curly hair is incomplete dominant over the straight. Wavy hair is produced in heterozygous states; this is an example of incomplete dominance.

When both HH' parents are crossed, then each parent will form the H and H' gametes. Out of the three offspring, one curly, two wavy, and one straight will be formed. The punnet square is explained below in the image.

Hence, when two people with wavy hair are crossed, three types of offspring are formed, such as those with curly, wavy, and straight hair. The genotype and phenotype ratio is 1:2:1.

All of the following are types of climate occurring along a coastline and are characterized by of precipitation, except Continental Climate

What precipitation means?

Any form of liquid or frozen water that condenses in the atmosphere and falls to the ground is known as precipitation. One of the three key phases of the global water cycle is it.

Continental climates are characterized by unpredictable weather patterns and wide temperature variations. The concept of continentality refers to how closely a region's climate resembles that of the interior of a large landmass. This type of climate develops in the mid-latitudes, where no body of water, such as the sea or ocean, regulates temperatures and the dominant wind blows overhead.

Due to the lack of a water body to maintain a milder winter and cooler summer, these areas have colder winters and hotter summers. This is true because rocks and dirt rapidly lose heat and have a smaller heat capacity than water. As a result, the continental climate is generally dry since air masses from distant oceans are lost before they can reach the area.

The Northern Hemisphere, which has the necessary huge landmass for the climate to develop, is where continental climate is most prevalent.
