1) melts polar ice caps thus causing the sea levels to rise
2) warms the oceans above average, causing sea life to either to migrate to places where they were never found before or die
3)causes algae blooms/ red tides which harms wild life and humans
Answer:
The correct answer is - the phenotypic ratio would be 9:3:3:1.
Explanation:
The two traits that are dominant are free earlobe and straight thumb that are denoted by the E and T on their alternative recessive alleles attached lobe and hitchhiker thumbs denoted by the e and t respectively. The heterozygous condition will be EeTt.
The cross between EeTt and EeTt will produce gametes ET, Et, eT, and et by each. The phenotypic ratio of the cross would be 9:3:3:1, which means 9 out of 16 offspring will be dominant in both trait, 3 will be free lobe and hitchhiker thumb, 3 will be straight thumb and attached earlobe, and 1 will be recessive in both traits. For the cross please check the attached image.
Thus, the correct answer is - the phenotypic ratio would be 9:3:3:1.
Answer:
To absorb neutrons before the neutrons can initiate more fusion reactions.
Explanation:
Control rods, usually made of compounds like graphite, absorb neutrons and prevent them from going everywhere and bombarding other molecules of the radioactive compound being used, usually U-238, and prevent a chain reaction from starting. When U-238 is bombarded with a neutron, it releases 3 others, which hit 3 molecules of U-238, releasing 27 neutrons in total, and so on. This must be controlled, otherwise an uncontrolled chain reaction could easily become highly explosive (Nuclear bombs that utilise U-238 use this principle to cause a chain reaction at a larger scale that releases huge amounts of energy that cause the initial explosion when the atom bomb is detonated).
Answer:
To organize them and speak about them accurately
Answer:
According to what has been investigated the option that should be supported by more scientific evidence: In psoriasis plaques, there are fewer T-cell clones, but there are often a large number of T-cells representing only a small number of clones (this is called oligoclonal expansion).
Explanation:
Oligoclonal expansion does not occur only in this pathology, it also occurs in other recurrent diseases such as multiple sclerosis, this phenomenon is widely studied and little discovered in some aspects and is mainly based on both tcd4 and tcd8 and b lymphocytes.
In this case, the presence of ltcd4 in psoriasis is very versatile and depends on the patient's immune response, which is why more scientific evidence is needed on this topic, based mostly on meta-analyzes.
