Answer:

<h2>A </h2>

Explanation:

1. A channel between two adjacent cells in known as an intercellular cleft.

2. And through these channels many molecules  can easily pass between cells.

3. Importance of Intercellular clefts:

i) It is very important in transportation of fluids and small solutes.  

ii) It contains gap junctions, tight junctions, desmosomes, and adheren proteins and these junctions help in regulate cell communication by signal transduction, surface receptors, or a chemogradient.

<h2>a) is the correct option </h2>

Explanation:

  • Capillaries are small exchange vessels (6-10 μ) composed of highly attenuated (very thin) endothelial cells surrounded by basement membrane − no smooth muscle
  • There are three structural classifications:
  • Continuous (found in muscle, skin, lung, central nervous system) − basement membrane is continuous and intercellular clefts (between adjacent endothelial cells) are tight (i.e., have tight junctions); these capillaries have the lowest permeability
  • Fenestrated (found in exocrine glands, renal glomeruli, intestinal mucosa) − perforations (fenestrae) in endothelium result in relatively high permeability
  • Discontinuous (found in liver, spleen, bone marrow) − large intercellular gaps and gaps in basement membrane result in extremely high permeability
  • Large surface area and relatively high permeability (especially at intercellular clefts) to fluid and macromolecules make capillaries the primary site of exchange for fluid, electrolytes, gases, and macromolecules

Answer:

Explanation:

Mitochondria is a double membrane bound organelle that is located in most eukaryotic organisms and it has a number of different shapes.

A mitochondrion has a outer and inner membranes made up of phospholipid bilayers and proteins which have different properties. Because of the double membraned organization, mitochondria have five distinct parts:

Outer mitochondrial membrane

Intermembrane space which is the space between the outer and inner membranes

Inner mitochondrial membrane,

the cristae space which is formed by the folding in of the inner membrane and

matrix which is the space within the inner membrane.

Mitochondria has a complex structure that allows for all the activities carried out by it this includes,Energy conversion, Pyruvate and the citric acid cycle, NADH and FADH2 which are the electron transport chain, Heat production and Storage of calcium.

What are the 3 types of RNA?
Tatiana [17]

mRNA or Messenger RNA
mRNA transcribes the genetic code from DNA into a form that can be read and used to make proteins. mRNA carries genetic information from the nucleus to the cytoplasm of a cell.<span>rRNA or Ribosomal RNA
rRNA is located in the cytoplasm of a cell, where ribosomes are found. rRNA directs the translation of mRNA into proteins.</span><span>tRNA or Transfer RNA
Like rRNA, tRNA is located in the cellular cytoplasm and is involved in protein synthesis. Transfer RNA brings or transfers amino acids to the ribosome that correspond to each three-nucleotide codon of rRNA. The amino acids then can be joined together and processed to make polypeptides and proteins</span>

In which zone would you expect to find the greatest abundance of marine organisms? middle intertidal zone supralittoral zone hig
serious [3.7K]

High littoral zone has greatest abundance of marine organisms.

<h3>What is High littoral zone?</h3>

The intertidal zone, also known as the "littoral zone," refers to the seashore that is covered during high tide and exposed during low tide, revealing a unique biome that survives under such fluctuating conditions.

<h3>Where are most marine organisms found?</h3>

The majority of ocean life can be found in coastal habitats on the continental shelf, despite the fact that this area accounts for only 7% of total ocean area. The majority of open ocean habitats are found in the deep ocean beyond the continental shelf. Species that live in the oceans and on the coasts can help to create new habitats.
