Organisms are classified as either a prokaryote or a eukaryote based on their _______.

Biology
1 answer:
Mrac [35]3 years ago
5 0

Answer:

The classification of organisms as either a prokaryote or a eukaryote is based on the structure of the organism's cell nucleus

Explanation:

The etymology of the word 'karyote' in both 'prokaryote' and 'eukaryote', is derived from a Greek word that explains the nucleus.

An organism having a true nucleus (i.e a nucleus surrounded by a nuclear membrane) in its cell(s), is classified as a eukaryote.

'Eu' in the word 'eukaryote', is derived from a Greek word that means 'true'.

A prokaryote is an organism that lacks a definite nucleus, hence, having its genetic materials suspended freely in the cyoplasm without a special nuclear membrane enclosing it, aside from its plasma membrane.

Infer How do dominant and recessive<br> factors interact? sc.7..16.1
Rama09 [41]

Answer:

The resulting characteristic is due to both alleles being expressed equally. An example of this is the blood group AB which is the result of codominance of the A and B dominant alleles. Recessive alleles only show their effect if the individual has two copies of the allele (also known as being homozygous) If you were to talk about dominant and recessive factors in human traits, such as brown/green eyes, brown would be dominant, only needing to be in 1 parent to pass down to the child. (i have no idea if this helps or not-- it's all i know.. sorry, ;w;)

1. Describe how pigments in the chloroplast play a role in coloring the plant and in producing energy.
kirza4 [7]

Answer:

Hello There!!

Explanation:

The purpose of the chloroplast is to make sugars that feed the cell's machinery. Photosynthesis is the process of a plant taking energy from the Sun and creating glucose. When the energy from the Sun hits a chloroplast and the chlorophyll molecules, light energy is converted into the chemical energy.

hope this helps,have a great day!!

Why does a deletion mutation usually cause more defects during protein synthesis than a point mutation?
BARSIC [14]
Answer: B

WHY?
Deletion mutation may cause a shift of base sequence, causing the reading frames for base sequence to change during translation. This may affect the type of amino acid it the original base sequence codes for, resulting in a change in amino acid sequence in the polypeptide translated. Therefore, affecting the whole protein itself. There may be wrong amino acids that prevents vital bonds like disulfide bridges to form, resulting in a huge change in 3 dimensional conformation of the protein. A point mutation may result in a gene sequence being edited. However, only the target sequence is being mutated. The rest of the gene sequences are left untouched. Therefore, the impact is localised. This ensures that even though a few wrong amino acids may be in the polyleptide, most of the bonds that are crucial for the correct 3 dimensional conformation is still present, therefore, lesser defects will be resulted due to point mutation as compared to deletion mutation.
