In humid conditions where surrounding air cannot hold further water vapour, sweat evaporates slowly, if at all. As a result the body heats up. it is difficult for the sweat to evaporate and in high humidity conditions we tend to sweat more. This explains why it feels so much hotter in high humidity.

The expression of flower color -qualitative character- and the length of the pollen grains -quantitative continuous character- is controlled by genes. Option A) TRUE.

Characters might be either qualitative or quantitative, discrete or continuous. In any case, genes are the units that control the expression of these characters.

A gene might be diallelic or multiallelic, and a character might be coded either by a single gene or by multiple genes.

The expression of the individual's phenotype varies according to the interaction between the involved genes and the inheritance pattern.

So characters are genetically determined. However, we need to consider that phenotype is also influenced by the environment.

Individuals are exposed to different environmental pressures that might lead them to express a different phenotype.

The phenotype depends on the interaction between the genotype and the environment. The environment, for instance, has a significant influence on the expression of quantitative characters like the length of the pollen grain.

In the exposed example,

Both of them are coded by genotypes. This is, their expression depends on the involved genes. However, in the case of lengths, the environment also plays a significant role in its expression.  

Option A is correct. The statement is TRUE.

Answer:

When a phenotype produced by certain alleles helps organisms survive and reproduce better than their peers, natural selection can increase the frequency of the helpful alleles from one generation to the next – that is, it can cause microevolution.

Explanation:

Because of having dominant traits certain traits increase in frequency in a population because they have.

A phenotypic trait is a specific variant of an organism's observable characteristics. Phenotype refers to any measurable, observable and obvious characteristics of an organism. It can be either hereditary or environmental, but usually occurs as a collection of both.

When any allele tends to determine the phenotype, when passed from parent to child, it called as dominant allele. In case of  homzygosity as well as heterozygosity, dominant allele can express itself.

Recessive in contrast is, when genotype is homozygous, the trait expressed is referred to as recessive trait. Therefore, certain traits increase in frequency in a population.

Water is self explanatory

Minerals can be gained from eating, drinking, and anything really

Fats are gained from foods with fat (obviously) and juicy foods like steak.

Vitamins are gained from eating certain things like an orange or even from the sun.

Carbs can be gained from food such as bread, beans, spaghetti..

Answer:

Nervous system

Explanation:

The nervous system can be divided into the central nervous system (CNS) and the peripheral nervous system (PNS). The autonomic nervous system is a part of the PNS which is concerned with the control of involuntary physiologic processes. During the exercise, the sympathetic nerves of the autonomic nervous system are in charge of preparing the body for physical activity by increasing the respiration rate, heart rate and blood pressure. The sympathetic nerves can also increase energy for the muscles by reducing insulin release and increasing blood glucose.

Evolution occurs from simple to complex organisms i.e from anaerobic prokaryotes, unicellular photosynthetic prokaryotes unicellular eukaryotes, multicellular eukaryotes. Correct answer is option (c).

According to the cell theory,

Eukaryotes are thought to have developed from prokaryotes approximately 2.7 billion years ago. The main difference between these two types of creatures is that eukaryotic cells have a membrane-bound nucleus, whereas prokaryotic cells have not.

Therefore, option (C) is correct because prokaryotes are the simplest cellular organism while eukaryotes are complex multicellular.

Answer:

I love my hometown as I love my home and I like to stay in the town streets as I stay in the rooms of my house.”

Everyone loves his hometown or city dearly. It is like loving the home or the place where one passes one’s life. My town is close to a canal that flows out of the river some eight kilometers away. Gardens and parks surround it on all sides. Beautiful flowers and tasty fruits of all the seasons are to be found welcoming you as you approach the town. Grassy grounds border the town where children, men, and women are found playing in the afternoon.

Grassy grounds border the town where children, men, and women are found playing in the afternoon.

The town has two colleges, one for boys and another for girls. It also has four high schools and six middle schools. The students are mostly from middle-class or rich families, but now some working-class people like laborers have started sending their children to schools. We have quite high standards of education as we have in some famous colleges and schools in the big cities. The reason is the hard work that teachers put in and the interest that most of the students take in studies.

The town has a fine public hospital where most government doctors attend to patients as well as they can the public dislikes the few careless doctors. They are often transferred on the public complaint. Of course, the hospital is often overcrowded and suitable medicines are in short supply. The richer people go to private clinics where they get medical treatment of their choice.

The town municipal committee keeps the town clean, but sometimes garbage heaps collect, and the whole place begins stinking (giving an unpleasant smell). The electricity department takes care that the streets are brightly lit at night. When people have complaints about its working, it begins performing better. The police and other government departments in the town, on the whole, have been performing their duties equally well. The people of the town have now started complaining of rising corruption in government offices. It is time we checked it with most strictly. When I am away from my town, I feel as if I am away from something dearest in life.
