Answer:

The correct statement is : Most prokaryotes live in communities

Explanation:

Electron microscopes are normally shows color of specimen in black and white. The part of the specimen passed through the electron appears white and rest of the part in black.

Flagella found in various microscopic organism such as protozoa, bacteria, archaea and some other eukaryotes for cell movement. Most of the prokaryotes are found in the colonies form however, these are unicellular entities but shows community formation. Plant cell does not require lysosomes as they have vacuoles for the function of lysosomes.

Thus, the correct statement is : Most prokaryotes live in communities.

olya-2409 [2.1K]

Answer:

  1. Respiratory system
  2. Nervous system
  3. Circulatory system
  4. Integumentary system
  5. Endocrine system

Explanation:

During excessive hard work or sports, the respiratory system acts to provide sufficient oxygen for energy supply (ATP) - a process takes place in mitochondria. At the very beginning, the respiratory system is active. If the person doesn't intake sufficient water, he will feel tired because of heavy breathing that increases body temperature and affects metabolic reactions. A supply of water would help decrease the respiration need and so support other systems.

The nervous system (hypothalamus) regulates the body temperature which is necessary for metabolic reactions taking place within the body, i.e. homeostasis. During and after exercise, the water intake was not sufficient, this means that the hypothalamus would work to maintain the temperature as well as other metabolic mechanisms. In the case of less water intake, the nervous system would be in stress.

The circulatory system acts to transport blood and oxygen to all parts of the body. During sports activities, the oxygen supply would be high to maintain energy supply. This takes place with the combined action of the circulatory system and respiratory system. For optimal functioning, the circulatory system needs fluids (water) intake because sufficient water is already lost during sports.

The integumentary system is the system that directly protects the body from damages including dehydration. Therefore, in this case, it will be highly active.

The endocrine system consists of glands that produce hormones to control body metabolism. The body metabolism, as mentioned before, is driven through water availability. The reduced water in the body would also put the endocrine system under pressure.

The second generation phenotypes resulting from the cross of purebred monohybrid pollination will display a ratio of _____. 2:2
Art [367]
The answer is 3:1.

If we imagine that plant has two alleles for the trait, we can dominant allele represent with P represents and recessive allele with p. To get purebred monohybrid in the first generation, parents must be a dominant homozygote (PP) and a recessive hetero<span>zygote (pp):

Parental generation: PP   x   pp
The first generation: Pp  Pp  Pp  Pp

Pp represents a heterozygote.
If we cross these heterozygotes:

The first generation: Pp   x   Pp
The second generation: PP  Pp  Pp  pp

If dominant allele determines the phenotype, there will be 3 plants (one PP and two Pp) with one phenotype and only 1 plant </span><span>(pp)</span> with another phenotype and vice versa.
