Which of the following pairs of protists and their ecological roles are correctly matched?
melisa1 [442]

Answer:

The correct pair is A: "apicomplexans—parasites of animals"

Explanation:

  • Euglenophyta is a group of unicellular, eukaryotic organisms. They are small, free-living forms, or parasites that present different feeding mechanisms and behaviors, such as heterotrophy, autotrophy, or mixotrophy.
  • Dinoflagellates are unicellular, flagellated, free-living protists that might form colonies. Most of them are autotrophic organisms but some of them are heterotrophic, or mixotrophic. In these last cases, dinoflagellates can feed on other dinoflagellates, protozoans, or diatoms. They can also be parasites.
  • Entamoebas are endoparasitic organisms with no mitochondria as an adaptation of living in environments with low oxygen concentration.
  • Apicomplexa is a unicellular, protist group. They have medical and economic importance as they are<u> animals</u> and human parasites. They have an apical complex that helps them to fixate to the host cell and release a substance that provokes an invagination in the host membrane. This invagination allows the parasite to get into the host cell.

A new moon occurs once every 29.5 days. Why must the Sun, Earth, and the Moon be aligned in order for the new moon to occur
Vsevolod [243]

Answer:

The sun, Earth and the moon are aligned, but because the moon's orbit is not exactly in the same plane as Earth's orbit around the sun, they rarely form a perfect line. When they do, we have a lunar eclipse as Earth's shadow crosses the moon's face.

Histologically, what feature is shared by all tonsils but is absent in other malt nodules?
ira [324]

Crypts Feature is shared by all tonsils but is absent in other malt nodules. Anatomical structures called crypts are deep, narrow incisions into larger structures. The Crypts of Lieberkühn are a typical type of anatomical crypt.

It is not the only form of the tonsil, though; some tonsils also feature crypts. The deep regions of these tonsils are accessible to the outside world through these crypts, making them more susceptible to infection. An intestinal gland, also known as a Lieberkühn crypt or intestinal crypt, is a gland that can be found in the small and large intestines' intestinal epithelium between villi (or colon).

The epithelium that covers the glans and intestinal villi are made up of a variety of cells, including enterocytes (which absorb water and electrolytes), goblet cells (which secrete mucus), enteroendocrine cells (which secrete hormones), cup cells, tuft cells, and Paneth cells (which secrete antimicrobial peptides) and stem cells at the base of the gland.
