Answer:
Answer is D. Variation does not exist within a kind.
Explanation:
Linnaeus is regarded as the father of classification. This is because, his method or system of classifying and naming of organism, known as taxonomy, is still relevant up till today.
He formulated the binomial nomenclature, which is the modern system of naming organisms.
Linnaeus system includes domain, kingdom, phylum, class, order, family, genus and specie.
A swamp is an area of a land that is permanently filled with water. It could be formed out from a former lake or pond overtaken by trees. It is also dominated by trees. Cypress and tupelo trees, bushes and shrubs grow in swamps and even tiny plants like the duckweed that almost covers the water surface.
A river is a large area where water flows to the ocean, the lake, etc. and its seawater consistently evaporates. Its source could be from a melting snow, a melting glacier, a lake with an out-flowing stream or a spring bubbling out of the ground.
Two reasons for the difference:
1. Swamps have many formed marine animals and insects while the river, you can only rarely find one (like fishes).
2. Rivers could be a source of water into houses, farms and even a drinking water for humans while swamps could not be a source for those.
The epithelium with a single layer of tall cells is classified as simple cuboidal epithelium.
Epithelium is one of the major types of body tissue that line the outer surfaces of organs and blood vessels throughout the body.
The epithelium performs the following functions that include:
- protection,
- secretion,
- secretion, absorption,
- excretion,
- filtration,
- diffusion, and
- sensory reception.
There are also different types of epithelium found in different parts of the body. A typical example is the simple cuboidal epithelium.
Simple cuboidal epithelium are single layered epithelium that are as tall as they are wide (cuboidal in shape).
They are found lining areas that are active in secretion and absorption.
Therefore, the epithelium with a single layer of tall cells is classified as simple cuboidal epithelium.

Answer:
In the mRNA sequence AUGGUGCAUGUC the maximum number of amino acids that can be encoded is 4 (option A).
Explanation:
Messenger RNA (mRNA) has a sequence of nitrogenous bases produced by the transcription of a DNA strand. This sequence of bases is organized in triplets or codons —made up of 3 nitrogenous bases— that can encode an amino acid, or mark the beginning or end —STOP codon—of protein synthesis.
From the sequence:
AUGGUGCAUGUC
Four codons are obtained, each of which encodes a different amino acid:
<em>Codons: AUG-GUG-CAU-GUC</em>
<em>Amino acids: Met - Val - His - Val</em>
<em>Methionine Valine Histidina and Valine are the four amino acids encoded by the 12 nucleotide sequence of the mRNA.</em>
