The Hawaiian Islands were formed by volcanic activity. ... In areas where the plates come together, sometimes volcanoes will form. Volcanoes can also form in the middle of a plate, where magma rises upward until it erupts on the sea floor, at what is called a “hot spot.

yulyashka [42]
Oxygen is a small molecule and it's nonpolar, so it easily passes through a cell membrane. Carbon dioxide, the byproduct of cell respiration, is small enough to readily diffuse out of a cell. Small uncharged lipid molecules can pass through the lipid innards of the membrane.

Stells [14]

The cytoplasm consists of a transparent liquid called cytosol, a supportive cytoskeleton and networks of membranes and organelles.

<h2>Reason :</h2>

The portion of the cytoplasm surrounding organelles is known as cytosol, which is that the liquid a part of the cytoplasm. it's composed of about 80 percent water and also contains dissolved salts, fatty acids, sugars, amino acids, and proteins like enzymes

What do i cell the fluid in the cytoplasm?

The cytoplasm is that the gel-like fluid inside the cell. it is the medium for chemical reaction. It provides a platform upon which other organelles can operate within the cell. All of the functions for cell expansion, growth and replication are administered within the cytoplasm of a cell.

What is the clear liquid in the cytoplasm called?

The cytosol, also referred to as cytoplasmic matrix or groundplasm, is one among the liquids found inside cells (intracellular fluid (ICF))

What is cytoplasm made up of?

Cytoplasm is that the gelatinous liquid that fills the inside of a cell. it's composed of water, salts, and various organic molecules. Some intracellular organelles, such the nucleus and mitochondria, are enclosed by membranes that separate them from the cytoplasm

What is cytoplasm ?

It is a fluid that fills the cell and occurs between the plasma membrane and the nucleus. Cell organelles like mitochondria, ribosomes, Golgi bodies, etc., are suspended within the cytoplasm. The cytoplasm helps within the exchange of materials between cell organelles.

4. A polypeptide has the following amino acid sequence: Met-Ser-Pro-Arg-Leu-Glu-Gly In the mutant below, indicate the type of mu
MatroZZZ [7]

Answer:

4. c. Deletion/ frameshift mutation

5. a. Tyr Tyr Asp Ser Gly

6. A frameshift occurred which altered the identity of the amino acids following the initiator 6. methionine, but not the length of protein Q.

Explanation:

4)

A single base pair at the first position of the Arg codon i.e. CGA has been deleted. Due to the deletion, the reading frame has shifted one nucleotide backwards, altering the amino acid sequence of the protein.

5)

The genomic DNA sequence is 5'-ATG ATA CTA AGG CCC-3'. Therefore, the complementary mRNA will be 5'-UAC UAU GAU UCC GGG-3'. According to the genetic code, this mRNA sequence encodes the following amino acid sequence: Tyr Tyr Asp Ser Gly

6)

The wild type DNA sequence is:

5'-ACUGUAAUGGAGUCAGAUGAUGCAUUAAGGAGAAAUUGAAAUAAA-3'

The mutant i.e. mRNA with the added G will be

5' ACUGUAAUGGGAGUCAGAUGAUGCAUUAAGGAGAAAUUGAAAUAAA-3'  

This is a single base pair insertion and frameshift mutation that shifts the reading frame one base pair forwards. The codon that was originally GAG coding for glutamic acid (Glu) gets converted to GGA that codes for glycine. Therefore, the amino acid sequence has been altered but the polypeptide chain will still have 13 amino acids.
