Answer:
True
Explanation:
Mitosis results in two cells that are genetically identical. DNA replication only occurs during "S phase." Meiosis is commonly defined as a type of cell division that divides a somatic cell and produces four gamete cells when doing so.
<u><em></em></u>
<u><em>S phase:</em></u> In S phase, the cell synthesizes a complete copy of the DNA in its nucleus. It also duplicates a microtubule-organizing structure called the centrosome. The centrosomes help separate DNA during M phase.
<u><em>Gametes</em></u> are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome.
Answer:
True
Explanation:
crystallisation- liquids cool to a solid-state to form crystals.
Answer:
Elastic fibers are made of elastin and microfibrils, that are elastic protein structures. The proteins can be stretched and resume normal shape. These fibers are found in parts of the body such as arteries, skin, lungs, connective tissue and heart that require some stretching. Marfan syndrome affects the elastic connective tissues causing symptoms like dilation of the aorta that doesn't resume normal lumen diameter (aortic aneurysm), and curving of the spine (scoliosis).
The lungs are unable to stretch and resume shape normally and this affects the respiratory system. The subjects will suffer from shortness of breath, wheezing and chest pain.
The sheath/endoneurium of neurons is connective tissue. This part of a neuron allows signals to travel effeciently along the axon of the neuron. This means that a person with Mafran syndrome has a slower response to stimuli that ordinary persons.
Answer:
The correct statements are A negative feed back regulation if free fatty acid accumulate C targeting the acetyl CoA transport shuttle in the mitochondrial membrane
Explanation:
The beta oxidation of fatty acid can be regulated by several following ways.
A The accumulation of free fatty acids exerts negative feedback during beta oxidation of fatty acids.As oxidation of fatty acids result in the breakdown of complex fatty acids in free fatty acids and acetyl CoA,the accumulation of free fatty acids lowers the rate of beta oxidation of fatty acid.
C The targeting of end product of beta oxidation that is acetyl CoA to the mitochondrial membrane also regulates the beta oxidation pathway.Because more the transport of acetyl CoA to the mitochondrial membrane more will be the rate of fatty acid break down by beta oxidation.
