Red blood cells are classifed as type A or type B, based on their surface antigens. Type O
blood does not contain any antigens. The chart below shows the possible phenotypes of
each blood type.

AB
Which mechanism explains how both A and B antigens produce type AB blood?
Answer:
codominance
Explanation:
The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.
what is antigen?The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles in a heterozygous individual are fully expressed in the phenotype. Therefore, in the case of blood type AB, the A and B alleles are codominant, and both antigens are expressed on the surface of the red blood cells.
Hence, The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.

average temperature to be lowest average temperature?
A) swamp, mountain, desert
B) swamp, desert, mountain
C) desert, swamp, mountain
D) mountain, desert, mounatin
Answer:
C
Explanation:
hope this helps
The list of biomes that shows environments from the highest average temperature to the lowest average temperature is desert, swamp, and mountain. Therefore, option C is correct.
What are biomes?Since they belong to certain areas or zones that, due to their geographical characteristics, share a climate, vegetation, and wildlife, biomes provide the primary support for the harmony of nature.
Any biome can include a wide range of habitats because the term "biome" is more general than "habitat." An area's climate and geography determine the biome classification. Communities that have adapted to the unique climate and ecology of the biome make up each one. Depending on the surroundings, they come in a variety of forms. The temperate deciduous biome is the ideal environment for human habitation.
The list of biomes that shows environments from the highest average temperature to the lowest average temperature is desert, swamp, and mountain. Therefore, option C is correct.

what role does isolation play in adaptive radiation ??
Answer:
Such exploitation of a new environment gives rise to an evolutionary pattern called adaptive radiation. Through migration, isolation, or possibly a new mutation giving rise to a brand new adaptation, a population of organisms moves into a new geographic area where that species never previously existed.

. A protease is added to a suspension of egg protein in a test-tube and kept at 37°C. After 8 minutes, the protein changes from cloudy to transparent. Which product, or products, will now be present in the test-tube
Answer:
amino acids
Explanation:
A protease is an enzyme capable of catalyzing the breakdown of proteins into polypeptide fragments and single amino acids, which are the building block of proteins. Proteases act by breaking peptide bonds by a process called hydrolysis, a reaction where water molecules break down peptide bonds (hydro means water and lysis means split). Proteases can be classified depending on the catalytic residue into cysteine, serine, threonine, aspartic, glutamic and metalloproteases.
The product that will be present in the test tube will be amino acids.
Protease is an enzyme that acts on protein by converting it into different
types of amino acids.
Amino acids are referred to as the building block of life and are important
nutrients in growth and replacement of worn-out tissues. The protease acts
on the protein by breaking the peptide bonds under the required
temperature.
An inadequate temperature may result in the denaturing of the enzyme
which was why the test was done at 37°C. This is the body temperature of
humans which led to the formation of amino acids which is absorbed by cells
of the body.

A wetland that contains a mixture of fresh water and salt water is called
an estuary
a stream
a river.
a pond
Answer:
an estuary
Explanation:
A wetland which contains a mixture of fresh water and salt water is called as an estuary. Thus, the correct option is A.
What is an estuary?An estuary is an example of a partially enclosed, coastal water body where the freshwater from rivers and streams mixes up with the salt water from the ocean bodies. Estuaries, and their surrounding lands, are the places of transition from the land area to the sea area.
Estuaries and their surrounding wetlands are the bodies of water which are usually found where the rivers meet the sea. Estuaries are the home to many of the unique plant and animal communities which have adapted to the brackish water, which is a mixture of fresh water draining from the land and the salty seawater.
Therefore, the correct option is A.
