Biology

Artist 52 [7]3 years ago

Answer:

4. Fluid (Flexible)

Explanation:

Plasma membranes must be very flexible in order to allow certain cells, such as red blood cells and white blood cells, to change shape as they pass through narrow capillaries. The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.

A researcher investigates a recently discovered species of plant. The plant has vascular tissues and exhibits a sporophyte and a
Anna71 [15]

The plant contains vascular tissue and has an alternation of generation. But, it lacks seeds. So, the plant is a Pteridophyte.

  • Vascular tissues are absent in thallophytes and bryophytes. They are found in pteridophytes, gymnosperms and angiosperms.
  • The sporophyte and gametophyte generation is common in bryophytes and pteridophytes.
  • Seeds are produced in plants that come under the group gymnosperms and angiosperms. The presence of seeds is the main characteristic of these groups.
  • Thallophytes, bryophytes and pteridophytes lack seeds. The reproduction in plants that comes under these groups occurs with the help of spores.

Thus, the recently discovered species of the plant should be classified based on the presence of vascular tissues, gametophytes and sporophytes. As pteridophytes contain vascular tissues, sporophytes and gametophytes and lack seeds, the plant is a pteridophyte

Describe the function of the filamentous structures pictured below.
vovikov84 [41]

Answer:

The hyphae of fungus serve as the main mode of vegetative growth.

Mycelia and hyphae are use to absorb nutrients from other organisms.

Explanation:

Fungi are either unicellular or multicellular organisms that are found in moist, slightly acidic and low oxygen environment. They are heterotrophs and decomposers.

Their cell walls are rigid and are composed of chitin and glucans. They are characterized by long filamentous structure called hypae. The structures of hypae form the mycelia.

The thyroid gland produces the thyroid hormones triiodothyroine (T3) and tetraiodiothyroinine (T4) which are dependent on the av
Sonbull [250]

Answer:

Iodine in the food items included in the diet

Explanation:

The thyroid hormones (T3 and T4) are the lipid-soluble hormones and are formed when iodine is attached to the amino acid tyrosine. The triiodothyronine (T3) has three atoms of iodine while tetraiodothyronine (T4) has four atoms of iodine attached to the benzene rings of tyrosine.  

Hence, the synthesis of T3 and T4 hormones by thyroid gland depends on the availability of iodine atoms which in turn mostly comes from the diet.  

Active transport of iodide ions occurs from the blood into the cytoplasm of the follicular cells of the thyroid gland. In fact, most of the iodide ions are concentrated in the follicular cells of the thyroid gland in the body. Diet serves as a source of iodine and the diet deficient in iodine leads to malfunctioning of the thyroid gland.
