Answer:

An autosomal trisomic condition is the deviation of the chromosome number where an extra copy of the chromosome present with the chromosome pair. The three trisomic conditions are Patau - extra copy at chromosome 13, Edward - extra copy of chromosome 18, and Down Syndrome - an extra copy of chromosome 21

Children or fetuses affected by these trisomies show the least life expectancy and develop as mentally week, other than these trisomies other trisomic conditions are highly lethal so we do not see the survivors and it is due to dosage sensitivity which means that increasing or decreasing their expression levels will reduce cell viability.

mario62 [17]

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.

The nursing instructor is talking with their students about botulism. The instructor tells the students that when caring for a c
NISA [10]

The condition which is most likely to cause death of a botulism patient is Respiratory failure.

Explanation:

The causal organism of Botulism is the bacteria <em>Clostridium botulinum.</em>

It is usually found in canned food and causes a very severe food poisoning.

The bacteria release botulinum toxin on reaching the intestine of the person and from their the toxins are absorbed into the blood.

Botulism mainly effects the neuromuscular system of the body. .

The basic symptoms of botulism is characterised by weaknes in limbs , jaws and eyes.

A decreased muscular activity sometimes causes constipation due to slowed down peristalsis.

Sometimes nausea , vomiting and diarrhea may occur.

If left untreated and in severe cases, the toxins may proceed to effect the respiratory muscle thus hindering the proper breathing and gaseous exchange.

A further damage could result in the respiratory failure.

Why are chloroplasts more on one side of a cell than the other
vaieri [72.5K]

You would be referring to the <em>plant </em>cell.

Answer:

Chloroplasts may be seen on all six sides of a plant cell, which is a three-dimensional entity with typically moderately rounded corners (not in the centre because a big central vacuole fills a very large part of the volume). Chloroplasts are constantly being rearranged by the cell since they are not set in place. Chloroplasts are typically located close to so-called periclinal cell walls, which are oriented in the same 2D orientation as the leaf surface under low light. Chloroplasts seem to "escape" to the anticlinal walls in bright light. Better light harvesting in low light by exposing every chloroplast to light and photoprotection by mutual shading in strong light are likely the fitness benefits provided by this behavior. In the dark, chloroplasts also gravitate toward the anticlinal walls. Thin leaves of submerged aquatic plants like Elodea can be used as microscope specimens to observe chloroplast motions. One can gauge how much light gets through a leaf in land plants. What I just said concerning the top layer(s) of leaves' "palisade parenchyma cells" is accurate. Most of the chloroplasts are found in these cells. Numerous cells in the spongy parenchyma under the palisade layer lack well marked peri and anticlinal walls.

<h2>How did plant cells incorporate chloroplasts in their DNA?</h2>

Chloroplasts must reproduce in a manner akin to that of some bacterial species, in which the chloroplast DNA is duplicated first, followed by binary fission of the organelle (a kind of protein band that constricts so that two daughter organelles bud off). As a result of some chloroplast DNA actually being integrated into the plant genome (a process known as endosymbiotic gene transfer), it is now controlled in the nucleus of the plant cell itself.
