Answer;
Chromosomes
Depending on the organism, the number of chromosomes in a cell may change.
Explanation;
When a cell in the body divides, it will pass on a copy of its DNA to each of its daughter cells. DNA is also passed on at the level of organisms, with the DNA in sperm and egg cells combining to form a new organism that has genetic material from both its parents.
Each species has its own characteristic number of chromosomes.Humans, for instance, have 46 chromosomes in a typical body cell (somatic cell), while dogs have 78. Like many species of animals and plants, humans are diploid (2n), meaning that most of their chromosomes come in matched sets known as homologous pairs.

Answer:
5' AUGUUUGAUCUU 3'
Explanation:
The nucleotide bases for mRNA are Adenine, Guanine, Cytosine, and Uracil. Uracil replaces Thymine (it's DNA counterpart). From this, you can eliminate options C and D.
Then it is just matching pairs: Adenine = Uracil , Cytosine = Guanine.

Answer:
5.1 billion metric tons of carbon is emitted by U.S as compared to other countries which emits about 32.5 billion metric tons of carbon.
Explanation:
U.S emits about 5.1 billion metric tons of carbon in the atmosphere which contribute in air pollution also helps in rising the temperature of the earth atmosphere because carbondioxide is a green house gas which increases the earth temperature. The main reason of high amount of carbon emission is the high number of industries and more fossil fuels is burnt in the engines of vehicles.
