The most likely source of thermal pollution in a river ecosystem would be <span>the use of water as a </span>coolant<span> by </span>power plants<span> and industrial manufacturers</span>. One harmful effect that this type of pollution has is a sudden change in water temperature (either a rapid increase or decrease) known as "thermal shock."<span>, killing fish and other native animals.

Answer:
1. B - Aa x Aa = 25% chance AA, which is the only genotype that results in sickle-cell. Aa is called "sickle-cell trait'; it isn't the full disease.
2. A - Aa x aa = we know will produce no homozygous dominant
3. B - RR x Rr = 1/2 chance of Rr (same problem as #5)
4. A - Bb x Bb = 1:2:1 ratio
5. B - WW x Ww = 1/2 chance of Ww
6. D - AABbCC has 5 dominant alleles, which is the most out of the four options
7. C - the one with the fewest dominant alleles will be the most green and the most successful in the environment
The process of fertilization involves the deposition of sperms into the vagina to the egg cell during sexual intercourse. Sperms make their way towards the cervix and uterus, and eventually goes to the fallopian tubes. <span>Only a few hundred will remain as they interact with the egg through the use of their heads and movement patterns.
</span><span>The process of implantation happens when the embryo, the fertimized eggs develops inside the fallopian tube after three days, and then travels to the uterus.</span>
Answer:
Operons afford the organism the opportunity to simultaneously regulate transcription of multiple genes, whose products are active in the same process.
Explanation:
Operon is the group of related genes and the operator and promoter sequences that regulate their expression. All the genes in an operon are expressed together and are under the regulation of the same promoter and operator sequences.
Operons consist of the genes that are involved in related metabolic pathways. For example, the genes that code for the enzymes of lactose catabolism are expressed together as lac operon. It allows simultaneous expression of the genes of lactose catabolism only when lactose is present in the medium. Similarly, these genes are inhibited simultaneously in absence of lactose by binding of repressor protein to the operator sequence.
