Answer:
A. 5-CAATTC-3'
Explanation:
Due to the spontaneous mutation of the cytosine, becoming uracil, the change in the new complementary strand would occur as follows:
5'-GAATCG-3 '-> Cytosine deamination = 5'-GAATUG-3' -> the new replicated complement is = 5-CAATTC-3 '
Remembering that Uracil equals a thymine in DNA, for that reason the mutated uracil base becomes Adenine when its synthesized in the new strand
Answer:
C) releases oxygen into the air
Explanation:
Stomata are the minute openings present in the epidermis of leaves. Plant open stomata to take in carbon dioxide gas from the air which in turn is fixed into organic compounds during the process of photosynthesis. Oxygen gas is the by-product of photosynthesis. Plants release oxygen from stomata into the air. Therefore, dermal tissues in leaves have stomata and one of their functions is to release oxygen into the air.
Ans.
The mutation that results in a mouse with less light fur as compare to other mice of same population, makes it easier for the mice to blend into their surrounding environment. According to law of natural selection, if a genetic mutation is beneficial for a population, the mutated organism survives to reproduce and that mutation gets transferred on to its offspring.
Thus, the correct answer is 'option). the mouse with the genetic mutation will survive and reproduce, and the trait (for fur) will spread over future generations.'
Well, there is no options to pick from so im going with my gut there are 2 uses for the horns:
#1. They were used for defense
#2. they were used to kill prey

All mammalian teeth share a similar structure: 1) the enamel crown, formed by epithelial cells; 2) the dentin found underlying the enamel, formed by mesenchymal cells and containing a large collagen component; 3) the pulp, the organ generating/supplying the dentin-forming cells (odontoblasts), and also containing ..
