Multiple sclerosis is a type IV hypersensitivity disease in which the cytotoxic T cells attack the myelin sheath of neurons.
Multiple sclerosis
The type IV hypersensitivity that affects the central nervous system is multiple sclerosis. The immune system of the body attacks the myelinated neurons which in turn results in the failure of delivering messages from the brain to various body parts. The disease can generally result in the permanent damage of various neurons in the body. The T cells attack the myelin sheath of the neurons in the central nervous system.

similarities in DNA, anatomical structures, and embryological development support common ancestry and evolution. true or false?
Answer:
true
Explanation:
A certain eukaryotic organism has multiple, distinct genes with highly similar sequences that are expressed at different times in the organism's life cycle. these genes could have arisen by:________
These genes could have arisen by gene duplication.
What is gene duplication?Gene duplication is the process of copying a section of DNA that codes for a gene. A retro transposition event or a recombination mistake are both potential causes of gene duplication. As a result, the duplicate gene coding may experience a significant number of modifications throughout time. This might prevent the gene from functioning or, in other situations, give the creature a benefit.
Gene duplication is a phenomenon that can happen through a variety of ways:
Ectopic Recombination: Uneven crossing-over between misaligned homologous chromosomes during meiosis might result in duplications. A duplication at the exchange site and a reciprocal deletion are the results of this recombination.Replication Slippage: Short genomic sequences can be duplicated as a result of the replication error known as replication slippage. DNA polymerase starts copying the DNA during replication, but eventually the polymerase separates from the DNA, causing replication to stall. The replicating strand is incorrectly aligned when the polymerase reattaches to the DNA strand, which accidentally results in several copies of the same portion.Aneuploidy: When a single chromosome's nondisjunction causes an abnormally high number of chromosomes, this condition is known as aneuploidy. Aneuploidy is frequently damaging and frequently causes spontaneous miscarriages in mammals. Some aneuploid people can survive. For instance, human trisomy 21 causes Down syndrome but is not lethal.Learn more about gene duplication here:

Which current is produced inresponse to a hyperpolarizing stimulus in a giant axon of a squid?
The giant axon of a squid, shows that hyperpolarizing stimulus is followed by transient inward capacitive current and lasting outward capacitive current.
Hyperpolarization is a change in a cell's membrane potential that makes it more negative. It is the opposite of a depolarization. It inhibits action potentials by increasing the stimulus required to move the membrane potential to the action potential threshold.
Hyperpolarization can be caused, for instance, by opening channels that allow positive ions to move out of the cell (or negative ions to move in).
The hyperpolarization-activated current is an inward current activated by hyperpolarization from the resting potential and is an important modulator of action potential firing frequency in many excitable cells.

What is the most likely effect of a mutation that changes the repeat sequence found in terc from 3’-cccaau-5’ to 3’-ucaggacg-5’?.
If the repeat sequence of telomere changes from 3’-cccaau-5’ to 3’-ucaggacg-5’ due to any mutation in TERC gene then the telomerase enzyme will be unable to attach to the 3' overhung of the telomere sequence and cannot elongate new DNA strand [telomeric part]. As a result, the telomeres of chromosomes cannot be elongated and the entire chromosome or the cell will be lost after a few rounds of division.
Telomere: They are short repeating sequences found at the end of the chromosome whose function is to save the chromosomes from degradation. But after each round of replication, the length of the telomeres becomes shorter than the previous and after a certain number of cell divisions, the telomeres become so short that they trigger the cell to stop dividing or to self-destruct (undergo apoptosis).
So, to prevent the shortening of telomeres, the TERC gene codes a telomerase enzyme which is a type of reverse transcriptase made up of two components: an RNA part that is complementary to the repeated telomeric sequence and a protein part that can add the nucleotides to the 3' end of the telomere.
After every cell division, the telomerase enzyme gets attached to the 3' end of the shortened telomere end and synthesizes the complementary DNA to the RNA part of the enzyme until the length of the telomere is restored again.

Exposing plants to light, heat, and wind caused the rate of transpiration to increase when compared to normal lab conditions because __________
Answer:
because the heat hitting the plant increased the amount of water pulled in by the plant because it increased the rate of evaporation on the leaves.
pleAse give brainliest
Exposing plants to light, heat, and wind caused the rate of transpiration to increase when compared to normal lab conditions because the plants need to open stomata for the gaseous exchange during photosynthesis. And at this time, the plant is highly exposed to high temperatures and heat, so the maximum amount of water loss occurs.
What is Transpiration?Transpiration may be defined as a process that generally involves the evaporative loss of water by plant cells. It occurs mainly through the stomata in the leaves.
Besides the loss of water vapor in transpiration, the exchange of oxygen and carbon dioxide in the leaf also occurs through such small pores known as stomata.
While in normal conditions plants receive all sources of processes and nutrients through artificial means, so they never undergo high exposure to climate alterations. Thus, the rate of transpiration remains almost the same in all possible instances.

Why is the nitrogen cycle important?
Answer:
It's very important because it helps in converting inert nitrogen gas into a usable form for the plants through the biochemical process. In the process of ammonification, the bacteria help in decomposing the animal and plant matter, which indirectly helps to clean up the environment.
Explanation:
Answer:
The nitrogen cycle is a biogeochemical process in which nitrogen, in various forms, is circulated from the atmosphere to the living organisms and later back to the atmosphere. Living organisms require nitrogen for the synthesis of nucleic acid and proteins. The atmosphere contains almost 78% of the nitrogen in an inert form (N2). Living organisms cannot use this nitrogen unless it is converted to ammonia, nitrates, and other usable compounds of nitrogen.
The nitrogen cycle is a cyclic process where the nitrogen travels from the inorganic form in the atmosphere to the organic way in the living organisms. The nitrogen cycle contains several steps, including nitrogen fixation, assimilation, ammonification, nitrification, and denitrification. This cycle is essential in maintaining a proper ecological balance and is present in both marine and terrestrial ecosystems.
