Answer:
i think it's more of a personal preference i would say carbon tax & biofuels
Explanation:
carbon tax would make people more aware of how much they are polluting the air and our atmosphere and the biofuels would help the earth in so many different ways. These 2 seem the best for me.
Answer:
Some phytoplankton are bacteria, some are protists, and most are single-celled plants. Among the common kinds are cyanobacteria, silica-encased diatoms, dinoflagellates, green algae, and chalk-coated coccolithophores.
Explanation:
In an organism's genomic data, 100 percent is made up of adenine, cytosine, guanine and thymine. Adenine and thymine are complementary pairs in a DNA so they should have the same concentration in the DNA. This would also be the case for Cytosine and Guanine. We are given 22 percent of thymine so we also have 22% of adenine. This would leave us with only 100-22 = 78 percent for both guanine and cytosine. And since they are present in equal amounts, we simply divide the remaining percentage by two to determine the amount of each. Therefore, there would be 78 / 2 = 39 percent of guanine present in that certain DNA.
Answer:
true
Explanation:
they might start off good but over a period of time short or long they will become a problem
Answer:
A) Chromosomes are made of DNA
C) Alleles are the different forms of a gene that can exist
D) Chromosomes contain genes that control the inheritance of traits.
Explanation:
Chromosomes are long molecules of deoxyribonucleic acid (DNA) that contain part (or all) of the genetic material of an organism. Humans contain 46 chromosomes organized in 23 pairs of homologous chromosomes (22 pairs of autosomal chromosomes and one pair of sex chromosomes, X and Y). Moreover, a gene is a physical segment of a chromosome that contains the information to encode a protein. Alleles are different forms of a gene (i.e., gene variants) that may be caused by mutations or genetic recombination. Humans are diploid organisms (2N: 46), and therefore we have two copies of each gene (alleles), one on each homologous chromosome.
