The two adaptations of endo parasites:

  • Endoparasites (a parasite that lives in the internal organs or tissues of its host) produce some compounds of anti-enzymes which defuse or inactivate the host's digestive enzymes.
  • Endoparasites maintain their osmotic concentration equivalent to or significantly lower than the host cell for easy absorption of host water and nutrients.

There are three main classes of parasites involve:

  • Protozoa include Plasmodium, the single-celled organism. A protozoa inside the host can only replicate, or split.
  • Helminths parasites are worms.
  • Ectoparasites: These are living on, not in their hosts.

In plants, chloroplasts are necessary for A. respiration. B. photosynthesis. C. secretion. D. both respiration AND secretion. E.
Ksivusya [100]

Answer:

B- Photosynthesis

Explanation:

Chloroplasts are <em>chlorophyll-containing, eukaryotic cell structures</em> that function in photosynthesis by absorbing energy from sunlight, combining this energy with water and CO2 to convert them to sugars . This cell structure is known as a plastid. The sugars produced, are important for the survival of the plant.

Chloroplasts reproduce on their own, independent of the whole cell because they contain their own DNA. Plant chloroplasts are located  in guard cells in plant leaves. Closely linked to these guard cells are tiny pores called stomata, which allow gas exchange required for photosynthesis.

Photosynthesis occurs in two stages:

  1. The light reaction stage
  2. The dark reaction stage

The Light reaction stage takes place in the presence of light. Clorophyll converts light into chemical energy in the form of ATP and NADPH. Both molecules produced, are used in the dark stage to produce sugar.

In the dark reaction stage, the stroma, containing enzymes, facilitates reactions leading to the production of sugars from ATP and NADPH. This process is also called the carbon fixation stage. The sugar produced can be stored in the form of starch for other processes such as respiration.

If a cells nucleus has 55% adenine bases, how many cytosine bases will be present?
Nostrana [21]

If a cell’s nucleus has 55% adenine bases it also has 55% thymine bases, so the percentage of cytosine bases is 45% as same as  guanine bases.

This is known as Chargaff's rule which states that DNA should have a 1:1 ratio of pyrimidine and purine bases (the amount of guanine should be equal to cytosine and the same thing with adenine and thymine).

DNA molecule globally has percentage base pair equality: %A = %T and %G = %C.

2. Being humans we have bilateral symmetry. What kind of symmetry do most cnidarians have and what
LiRa [457]

Answer:

See explanation:

Explanation:

Humans are the same, one side to the other. The human body is a mirror image, one side to the other. The cnidarian phylum does not necessarily have bilateral symmetry. Body forms like jelly fish, sea anemones, and coral are examples of cnidarians. Note that jelly fish may be somewhat symmetric, but not totally and not in the same way that the human body is.
