Answer: <em>D. Causes an accumulation of lipids in brain cells</em>
Explanation:
Tay-Sachs disease is caused by a genetic mutation in the <em>HEXA</em> gene. It is an autosomal recessive disease that causes the mutation on an enzyme, which metabolizes <em>GM2 Ganglioside</em> in nerve cells, this leads to a build-up of the molecule in brain cells. At the moment there is no cure for the disease, only support treatment is available.
Answer:
3. Endotherms spend more energy on internal temperature regulation compared to ectotherms.
Explanation:
Ectotherms, are considered as cold-blooded animals (reptiles and amphibians), and are organisms that don't have the ability to generate enough heat to keep themselves warm. Endotherms, in contrast, do possess the ability to generate their own body heat.
Endotherms also called warm blooded animals (mammals) have the ability to regulate their body temperature by themselves. If the endotherms are in a cold place their body increases the metabolism and generates more heat. This will compensate for the cold outside.
DescriptionA mesopredator is a mid-ranking predator in the middle of a trophic level, which typically preys on smaller animals. Mesopredators often vary in ecosystems depending on the food web.
hope this helped :)
The first trophic level
they would want to eat the primary producers, which are located at the first trophic level. due to the 10% rule only 10% of the energy from the previous trophic level is passed on.
<span>The reaction
that takes place in the stroma is collectively known as the Calvin Cycle. The
stroma is responsible for the 2nd stage of photosynthesis where ATP
and NADPH are used to capture and reduce carbon dioxide in the plant cell.</span>
<span>
It is a fluid-like organelle that surrounds the grana within the
chloroplast in plant cells. The stroma is also responsible for storing
chloroplast DNA and chloroplast ribosomes where molecular processes like
replication and transcription/translation of chloroplast proteins occur.</span>
