Answer:
The progeny produced is 100% heterozygous individuals.
Explanation:
Remember that in Mendel crosses, there are two alleles for each character, in this case for the color of the flowers.
When the problem refers to pure varieties, it refers to individuals with two equal alleles for the same gene.
If two pure varieties with antagonistic characters intersect, 100% of heterozygous individuals will be obtained in the offspring.
As for its phenotype, it will depend on which allele is dominant over the other.
Answer:
Dehydration
Explanation:
What causes bacteria to die in an extremely salty environment is dehydration due to the loss of osmotic balance in their cells.
Water molecules would normally move from the region of high water potential or low solute concentration to the region of low water potential or high solute concentration through a biologically permeable membrane.
<em>An extremely salty environment would be hypertonic to the cells of bacteria and the cell walls of bacteria act as biologically permeable membranes. Hence, the bacteria cells lose water due to the osmotic movement of water from their cells to the surrounding salty environment. </em>
Answer:
Hypothalamus
Explanation:
It maintains the process that leads the activation of wakefulness or alertness of the cerebral cortex
Answer: If the concentration of glucose inside the cell is higher than the one outside the cell, glucose molecules will move from inside the cell to the outside of the cell in a process of diffusion.
Explanation: Diffusion is the movement of solute molecules from a region of higher concentration to a region of lower concentration. The inside of the cell has higher glucose concentration i.e., has higher quantity of glucose molecules than outside of the cell which has a lower glucose concentration, therefore glucose molecules will move from inside the cell to outside the cell. The purpose of this is to create a balance in glucose concentrations in the two environments.
