Not having enough energy within the cells, injury and/death could occur.
Answer:
Translocation
Explanation:
Changes occur to the nuclear material from time to time. These changes are referred to as MUTATIONS. A mutation is a change in the nucleotide sequence of a gene. Mutations are of different types depending on how it occurs.
According to this question, the kind of mutation/abberation described is TRANSLOCATION. Translocation is a kind of chromosomal abnormality in which one segement of a chromosome containing certain genes breaks off and reattaches to a different chromosome.
This is the case in this question regarding the genetic composition of corns where genes for waxy and virescent kernel appearance occur in the same chromosome. It was found out that, in a stock of corn, these two genes are now on different chromosomes. This means that a segment of the chromosome containing one of the genes broke off and got reattached to a different chromosome. Hence, TRANSLOCATION MUTATION has occurred in this stock of corn.
The lungs.
The lungs are paired, cone-shaped organs which take up most of the space in our chests, along with the heart. Their role is to take oxygen into the body, which we need for our cells to live and function properly, and to help us get rid of carbon dioxide, which is a waste product.
Answer no 1:
The correct option is B) Parasitism benefits only one organism, while mutualism benefits both organisms.
Explanation:
A symbiotic relationship can be described as a type of interaction among different organisms living in an area. Some organisms might benefit from this relationship, others might not be affected while some might be harmed.
A symbiotic relationship in which one organisms gains benefit while the other gets harmed is called parasitism. For example, ticks that live on a cat.
A symbiotic relationship in which both organisms benefit from each other is termed as mutualism.
Answer No 2:
<em>The correct option is A) It is given off as heat.</em>
Explanation:
Not all of the energy is transferred from one trophic level to another when an organism consumes another organism from the trophic level below it. Scientists have calculated that only 10% of the energy gets transferred from the lower trophic level to the upper trophic level. Studies have shown that most of the energy is lost in the environment as heat and hence, only 10% of the energy gets transferred.
Uranium extraction from seawater: Uranium is most often mined from the Earth's crust, but it can also be extracted from seawater, which contains large quantities of uranium<span> (3.3 ppb, or 4.6 trillion kg). Theoretically, that amount would last for 5,700 years using conventional reactors to supply 15 TW of power.</span>
