Answer:
It assembles the messages in a way that has meaning for us, and can store that information in our memory. The brain controls our thoughts, memory and speech, movement of the arms and legs, and the function of many organs within our body. The central nervous systemis composed of the brain and spinal cord.
Answer:
Based on the given information , the cellular structure , which don not function properly in Tay Sachs disease is <u>Lysosomes </u>
Explanation:
<u>LYSOSOMES -:</u> In many animal cells, a lysosome is a membrane-bound organelle. These are spherical vesicles containing hydrolytic enzymes that can break down many types of biomolecules. A lysosome, with both its membrane proteins and its lumenal proteins, has a particular composition. There are a number of enzymes in lysosomes, helping the cell to break down different biomolecules that it swallows, including peptides, nucleic acids, carbohydrates , and lipids (lysosomal lipase). For optimal function, the enzymes responsible for this hydrolysis need an acidic environment.
<u>TAY SACHS DISEASE -: </u>The autosomal recessive disorder Tay-Sachs is caused by mutations in both gene alleles (HEXA) on chromosome 15. HEXA codes for the enzyme β-hexosaminidase A alpha subunit. This enzyme is contained in organelles, lysosomes, which break down large molecules for the cell to recycle.
Normally, β-hexosaminidase A helps to degrade a lipid called ganglioside GM2, but the enzyme is absent or present only in very small amounts in Tay-Sachs individuals, enabling excessive accumulation of ganglioside GM2 in neurons. In the different types of Tay-Sachs, the progressive neurodegeneration seen depends on the speed and degree of accumulation of GM2 ganglioside, which in turn depends on the amount of functional β-hexosaminidase A present in the body.
Hence , the answer is<u> lysosomes .</u>
The nine major animal phyla in the context of animal phylogeny are Phylum Porifera, Phylum Cnidaria,Phylum Platyhelminthes, Phylum Echinodermata, Phylum Mollusca,Phylum Nematoda,Phylum Arthropoda, Phylum Annelida and Phylum Chordata
<h3>What is animal phylogeny?</h3>
The animal phylogeny is defined as the division of the animal kingdom according to groups which are due to the type of tissue and their various body symmetry.
The type of tissue and body symmetry of the various animals of the nine major animal phyla include the following:

Answer:
They become thirstier.
Explanation:
Speaking of drinking, you should really be drinking water right now so you don't get unhydrated.
A (very) brief definition of Eutrophication is the over-enrichment of a river or lake with nutrients, typically as a result of surface run off from nearby fields that have been fertilised artificially.
This leads to excessive algae growth, which, through a lot of steps, basically kills everything in the lake.
