Which part of the neuron receives electrical impulses and is made of branched fibers? a. myelin sheath b. node of ranvier c. axon d. dendrites

Answers

Answer 1
Answer:

Answer:Dendrites

Explanation:
Answer 2
Answer: dendrites
Most neurons possess these branch-like extensions that extend outward away from the cell body. These dendrites then receive chemical signals from other neurons, which are then converted into electrical impulses that are transmitted toward the cell body.

WHAT HAPPENS TO THE CARBON ATOM DURING PHOTOSYNTHESIS

Answers

 the carbon dioxide that is,CO2 is split into carbon and oxygen ,the some of the oxygen is released and the carbon is mixed with water that is H20,if you construct and equation for the reaction between carbon and water you will see that the product is glucose(sugar) 
that is why we say that during photosynthesis plants take in water and carbon dioxide in order to manufacture their food(which is glucose) and to release oxygen

What’s the mRNA sequence?
What will be the amino acid sequence?
Will there likely be effects?
What kind of mutation is this?

Answers

mRNA Sequence: AUGUGGAACCGUGACU

Amino Acid Sequence: Methionine-Tryptophan-Asparagine-Arginine-Cysteine.

Likely Effects: Minimal impact, as the mutation is a silent mutation, not changing the amino acid.

Mutation Type: Point Mutation.

To find the mRNA sequence, we need to perform transcription, where DNA is used as a template to synthesize complementary mRNA. In this case, we have a substitution mutation in the DNA sequence, so the mRNA sequence will also be affected.

Original DNA Sequence: T A C A C C T T G G C G A C G A C T

Mutated DNA Sequence #5: T A C A C C T T G G G A C G A C T

The mRNA sequence is formed by replacing T with U (uracil) in the DNA sequence:

Original mRNA Sequence: A U G U G G A A C C G C U G C U G A

Now, let's determine the amino acid sequence using the mRNA sequence. Amino acids are coded by codons (three-letter sequences). Here's the mRNA sequence grouped into codons:

AUG UGG AAC CGC UGC UGA

The codons code for specific amino acids:

AUG: Methionine (start codon)

UGG: Tryptophan

AAC: Asparagine

CGC: Arginine

UGC: Cysteine

UGA: Stop codon

So, the amino acid sequence is Methionine-Tryptophan-Asparagine-Arginine-Cysteine.

As for potential effects, the mutation seems to result in a single amino acid change (from glycine to asparagine). Whether this has significant effects on the protein's function depends on its role. If the protein is critical for an essential function, even a single amino acid change can have noticeable effects. However, if it's a less crucial protein or a non-coding region, the impact may be minimal.

This mutation is a point mutation, specifically a missense mutation, where one nucleotide is substituted with another, leading to an amino acid change in the resulting protein.
