Almost all animals share the following characteristics except

Biology

Aleks [24]3 years ago

The correct answer is A.

Animal cells do not have a  cell wall.

A cell wall is the rigid, outermost covering of plant cells and is made up of cellulose.  It is absent in animal cells. The cell wall is visible under a light microscope.

Animal cells are instead covered by a cell membrane. It is made up of lipids, proteins, and small amounts carbohydrates. It is a thin and delicate structure  that can only be seen using an electron microscope.

Liula [17]

Answer: Golgi aparathus.

Explanation:

Golgi aparathus is an organelle that is found in eukaryotic cells. Soluble protein can enter Golgi aparathus in folded conformation because the golgi aparathus is a complex vessicles and folded membrane that help to package, transport and modify proteins and deliver them to the right location they will be needed.

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.

jekas [21]

Answer:

B.) water mold

Explanation:

The water mold is a filamentous fungus like organisms that lives in  brackish water, fresh water or wet soils. They are saprophytic, that is, they live on dead organisms. Their reproduction is usually by motile asexual spores (zoospores).The zoospores are of two types namely pear-shaped with apical flagella and kidney-shaped with two flagella on the concave side. Water mold are usually identified by their zoospores.
