b.no effect on the cell or organism
c.enhanced ability of the organism to reproduce
d.change to the phenotype of the organism
Answer;
c. enhanced ability of the organism to reproduce
Explanation;
-It is vital that humans have the correct balance of chromosome material. This is because the genes, that instruct the cells in our body, are found on the chromosomes.
-Any change in the number, size or structure of our chromosomes can mean a change in the amount or arrangement of genetic information.
-Human cells normally contain 23 pairs of chromosomes, for a total of 46 chromosomes in each cell. A change in the number of chromosomes can cause problems with growth, development, and function of the body's systems. These changes can occur during the formation of reproductive cells (eggs and sperm), in early fetal development, or in any cell after birth.
We are given with 2 genes homozygous tall plants (TT) with homozygous short plants (tt). The ensuing offspring are tall, which implies the dominant attribute is tallness. this can be true since the chance of various height like all are short or some are tall and short could also be doable. answer is a
allele for tall plant height was dominant
Explanation:
Gregor Johann Mendel, called the "father of recent biology," was born in European country in 1822. His experiments showed that the inheritance of bound traits in pea plants follows explicit patterns, later turning into the inspiration of recent biology and resulting in the study of heredity.
It results in 50% recombinants.
It reduces the percentage of recombinants.
Answer:
It reduces the percentage of recombinants.
Explanation:
The independent assortment of genes gives rise to new gene combination and recombinants. Linkage refers to the tendency of two genes present in the vicinity on the same chromosome to get transmitted together.
Since the linked genes are inherited together, they do not exhibit independent assortment. Due to the absence of independent assortment in linked genes, more of parental types and lesser recombinants are formed.
A decrease in plant life would have no effect on the atmosphere.
b.
A decrease in plant life would cause carbon dioxide levels to increase and oxygen levels to decrease.
c.
A decrease in plant life would cause carbon dioxide levels to decrease and oxygen levels to increase.
d.
A decrease in plant life would cause an increase in all gases in the atmosphere.
The answer is B because without plants, the earth would have no natural way to recycle and generate oxygen and consume carbon dioxide
Answer:
D. Both a and b
Explanation:
The difference in ion concentration between the intracellular and extracellular fluids in a cell is due to both active ion transport and passive diffusion of ions.
The difference in ion concentration between the intracellular and extracellular fluids in a cell is primarily due to both active ion transport and passive diffusion of ions. Active ion transport refers to the movement of ions across the cell membrane using energy, such as through ion pumps or channels. Passive diffusion, on the other hand, occurs when ions move down their concentration gradient without the need for energy.
For example, the sodium-potassium pump actively transports three sodium ions out of the cell for every two potassium ions it brings in. This creates a higher concentration of potassium ions inside the cell compared to outside. Meanwhile, passive diffusion allows ions like chloride, calcium, and potassium to move across the cell membrane through ion channels, either facilitated by a concentration gradient or electrical potential.
In summary, the difference in ion concentration between the intracellular and extracellular fluids in a cell is due to both active ion transport and passive diffusion of ions.
