Answer:
Chloroplast
Explanation:
Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process.
Answer:
There are no options to this question, however, the question can be answered. The answer is:
FF and FF/Ff
Explanation:
This question involves a single gene coding for possession or not of freckles in humans. The allele for freckles (F) is dominant over the allele for no freckles (f). This means that genotypes FF and Ff (heterozygous) will possess freckles while only genotype ff will not.
According to this question, a couple has several children in which all of the children have freckles i.e. have either genotype FF or Ff. This is as a result of the fact that the parent's genotypes were either FF or Ff. That is, one parent is FF while the other is either FF or Ff. This genotypes will only produce children with freckles.
Answer:
The plant would wilt with low turgor pressure.
Explanation:
Turgor is what makes living plant tissue rigid. Loss of turgor, resulting from the loss of water from plant cells, causes flowers and leaves to wilt :3
Answer: Sulfa antibiotics target a specific enzyme that inhibits bacterial growth. ... Viruses are unaffected by antibiotics because they do not have peptidoglycan cell walls or ribosomes, and they do not replicate their own DNA. Bacteria can become resistant to antibiotics through the process of selection and evolution.
Explanation:
Move three sodium ions out of a cell and two potassium ions into a cell while consuming an atp for each cycle
Explanation:
By pumping three (3) Na+ to the outside and two (2) K+ to the inside of the cell, there is a net positive charge on the outside leaving the inside of the cell electronegative. This process is achieved by the Na+/K+ pump and is a process that consumes ATP energy.
This is much more important in a neuron cell who ¾ of its energy is used to maintain a -70mV resting potential that is important for the nerve to pass impulse when depolarised.
In other cells, the gradient created in important in maintaining the homeostatic osmolarity inside the cell to avoid swelling and lysis of cells due to uptake of excess water by osmosis. The Na+ gradient is also used to import other molecules into the cell such as glucose and amino acids. These molecules are coupled with Na+ and then are absorbed efficiently as the Na+ flow back inside the cell down the Na+ concentration gradient.
