Homozygous- a certain gene that carries two copies of the same alleles
Answer:
Capsule
Explanation:
In many bacterial species, an extracellular layer composed of a polysaccharide especially a monosaccharide is produced around the cell wall of the bacteria. This extracellular layer is known as the slime layer or the capsule.
The capsule in bacteria serves many purposes like it protects the bacteria from the destruction by the white blood cell in the host, it enables the bacteria to adhere to the substrates and protect it.
In the plant group called the bryophytes also a capsule structure is present which grows in the sporophytic phase and encloses the spores, therefore, the capsule is considered the sporangium of the bryophytes.
Thus, the capsule is correct.
Answer:
Explanation:
Insertion/deletion of 3 base which is a condon will be less fathal because only one amino acid will be missing from the protein of which the gene codes for.
If one codon is deleted it will still be the same but might cause a disease for example in cystic fibrosis one amino acid, 508th Phenly alanine is missing in the CFTR protein. They severity of diseases caused by Insertion or deletion is increased as the number of condon are more.
However, if only one or two is deleted/inserted then all the codons will shift causing them to be in different groups which may form a totally different amino acids as seen in frameshift mutation. This is more dangerous.
D. Limber Pine Trees is the correct answer
Mushrooms are decomposers, pine martins and snowshoe hairs are both consumers, so that leaves you with limber pine trees.
