The one for the cells is the
cells need to be able to get oxygen gas nutrients and get carbon dioxide out quickly.
i’m not sure for the other ones
If A is dominant allele, and a is recessive allel, than:
p is frequency of A allele, q is a frequency of a allele, p2 is a frequency of homozygous dominant genotype, 2pq is frequency of heterozygous genotype and q2 is frequency of homozygous recessive genotype.
If the population is in Hardy-Weinberg equilibrium; p+q=1
p=0.15 q=1-0.15=0.85
2pq=2*0.15*0.85=0.255~26%
Answer:
DNA
Explanation:
DNA is a nucleic acid. It is a polymer of deoxyribonucleotides that are bonded together by phosphodiester bond to make long DNA strands. DNA is the most stable biomolecule in the history of life on earth and continues to serve to store the genetic information of living beings. Several species-specific sequences are DNA are conserved during evolution. This makes the DNA the best molecule to store any valuable information.
RNA is comparatively more reactive and prone to mutations due to the presence of ribose sugar and uracil base in it. The structure of a protein is determined by DNA nucleotide sequences. Any change in DNA would also change the structure of a protein.
Tissues
Cells when grouped form tissues, when group of tissues are formed together they make organs, some organisms skip from organs to organs systems to form an existing organism as a whole<span>. Describing how is the cells group </span>is the process of multiplication of cell or the so-called cell division, mitosis.<span> This mechanism of each cell produces another cell that binds together and produces again, repeatedly, to be a larger system called now the tissue as explained earlier. </span>
Invertebrates are what they can be classified as
