Answer:
A homozygous dominant trait will have both the dominant alleles of a gene for a trait. For example, the AA genotype of the 80 brown gerbils.
A heterozygous trait will have one dominant and one recessive allele for the particular gene. For example, the Aa genotype of the 64 brown gerbils.
A recessive trait will be the trait in which there is no dominant allele for the gene. The suppressed trait only occurs when both the alleles of the gene are recessive. For example, the aa genotype of the black gerbils.
The completed table is shown in the attachment.
Your answers would be:
1. ---- B. A cell cannot be subdivided into smaller units that maintain the living state.
2. ---- The organism is a eukaryote because it has a nucleus.
3. ---- D. Water would flow into them because they are hypertonic to external environment.
If you want to know why:
1. The cell is the basic unit of life or in other words, its the smallest unit that makes up a living thing. It does not subdivided further if you are talking about sustaining life. Yes, it is made up of smaller units of organelles, but these organelles work together as a single unit (as a cell), to do life sustaining processes.
2. The organism is a eukaryote because of the presence of a nucleus. This is one of the main features of a eukaryote that differentiates it from a prokaryote. Prokaryotes to not have a true nucleus.
3. Water would flow into them, causing the cell to swell and eventually burst if the concentration of solutes would not even out before then. The process of osmosis is what brings the water into the cell. The cell would have a higher solute concentration than freshwater. Through osmosis, the water would then go to the area of higher concentration, which would be the cell.
Answer:
DNA makes us all unique by controlling the production of <u>gene</u> that make us look different and have the structures to better survive within our <u>environment</u>.
Explanation:
DNA is the molecule that contains the genetic information, dependent on the sequence of nucleotides that form its structure.
Chromosomes are formed by a DNA molecule, whose fragments form genes, structures that define every characteristic and function of a living being.
The <u>characteristics expressed by the genes differentiate individuals of the same species and other species</u>, allowing their functions, including <u>survival in their environment</u>.
