It effects the body by causing symptoms like muscle aches, low-grade fever, headaches, sometimes rashes, swelling of the lymph glands may also occur, and flu-like illness. These are symptoms after a few weeks of being infected.
Answer:
I'll inform them that the possibility of all their future children/offspring being phenotypically sickle-celled is very high.
Explanation:
Sickle cell is an inherited disease condition in which the red blood cells of the blood loses its shape and hence, dies or gets broken down. It has to do with the blood genotype of an individual. There are three major types of blood genotypes in humans namely: AA, AS, and SS. SS is the recessive genotype that codes for the sickle cell trait.
Hence, a human with the sickle cell trait has a genotype- SS. Therefore, according to this question, a man and a woman, each with sickle-cell trait (SS), were planning to marry, This will mean that both the man and the woman will always produce a gamete with S allele, which will combine to form an SS offspring. In other words, all of the offsprings of this man and woman will be sickle-celled.
Answer:
These crops where improved with technology, production of high-yielding variety, and improve farm practices. All these ensured the crops of green revolution had increase yield.
Explanation:
Through genetic engineering, high-yielding variety of cereals e.g wheat, maize, rice, were genetically engineered so that certain features which enhanced increased productivity were selected for.
Use of fertilization, the adoption of mechanization,good cropping and farming system are other factors which enhanced yield of these crops. Specifically, these crops were modified to enhance their Nitrogen uptake, which promotes rapid growths.
B is not correct because new molecules are formed so numbers can change. D isn't correct because the color often changes, for example metallic iron and clear oxygen form red rust. The arrangement of the atoms changes, too so a isn't correct. C is cotrect
There would be half the number of chromosomes in the gametes...so 4.
