Answer:
True
Explanation:
There are certain limitations associated with the Punnett Squares. They are not useful in case of complex genetic inheritance such as linkage between two genes. In case of linkages it becomes difficult to estimate the distribution of genotypes and phenotypes. For example in case of Nail-patella Syndrome and gene associated with blood group two genes lie on the same chromosome in close vicinity and hence there are high chances of inheritance of these traits in the offspring from the parent thereby causing random distribution of the two traits. This random distribution cannot be captured through punnet square.
The same problem is associated in case where a single gene is determined by multiple genes with graded effects of each gene.
The correct answer is Chloroplast
Mitochondria is the powerhouse of the cell while the cell wall protects the cell from outside influence.
Answer:
they give the lungs a really big surface area. they have moist, thin walls (just one cell thick) they have a lot of tiny blood vessels called capillaries.
The walls of the alveoli are only one cell thick. This makes the exchange surface very thin - shortening the diffusion distance across which gases have to move. Each alveolus is surrounded by blood capillaries which ensure a good blood supply.Adaptations of the alveoli:
Thin walls - alveolar walls are one cell thick providing gases with a short diffusion distance. Moist walls - gases dissolve in the moisture helping them to pass across the gas exchange surface. Permeable walls - allow gases to pass through.
Explanation:
Have great day
Answer:
I believe its option b. carbon dioxide.
Answer:
Control group remains unchanged.
Explanation:
For example if you are trying to see if watering plants with Pepsi is better.
Your experiment plant would get watered with Pepsi.
Your control plant would get watered with water. (Control groups serve as a reference to compare in the experiment)
