Since their are more sodium ions outside the cell at test, if a cell becomes freely permeable to sodium ions and is not regulated, the membrane potential will be positive.
What is membrane potential?The membrane potential is the potential difference across a neuronal membrane due to the difference in the concentration gradient of oppositely charged ions.
At rest, the inside of the membrane is negative while outside is positive due to more sodium ions being outside the cell.
Therefore, if a cell becomes freely permeable to sodium ions and is not regulated, the membrane potential will be positive.

Explanation:
Which species is most likely to exhibit clumped dispersion? a. dandelions with seeds dispersed by the wind b. tigers that defend their territories from one another c. a bird that nests in many different types of trees d. a tree that grows only on the banks of streams
The species that is most likely to exhibit clumped dispersion is a tree that grows only on the banks of streams. So, the correct option is D.
What do you mean by Species?A biological species may be defined as a group of organisms that can reproduce with one another in nature and produce fertile offspring.
Clumped dispersion is a type of population dispersion of a particular species. It represents the mechanism of spacing between the individual of a species. It is a common type of population dispersion that takes place through attraction.
Therefore, the species that is most likely to exhibit clumped dispersion is a tree that grows only on the banks of streams.

33. Why is it beneficial that plants have two kinds of chlorophyll (a and b)?
Answer:
chlorophyll in plants complement each other in absorbing sunlight.
Explanation:
light with a wavelength of 460 nm isn't always substantially absorbed by means of chlorophyll a, but will as a substitute be captured through chlorophyll b, which absorbs strongly at that wavelength. the two forms of chlorophyll in flowers
It is beneficial to have two kinds of chlorophyll in photosynthetic plants because both types of chlorophyll work complementary to each other and allow maximum absorption of light in the blue to red spectrum.
What do you mean by Chlorophyll?Chlorophyll may be defined as the green-colored pigment in plants, algae, and cyanobacteria that is essential for photosynthesis.
Chlorophyll A absorbs the light of wavelength 400 to 450nm with maximum intensity and 650 to 700nm with minimum intensity.
Chlorophyll B absorbs the light of wavelength 450 to 500nm with maximum intensity and 600 to 650nm with minimum intensity.
Therefore, it is beneficial to have two kinds of chlorophyll in photosynthetic plants because both types of chlorophyll work complementary to each other and allow maximum absorption of light in the blue to red spectrum.

Why is the percentage similarity in the gene always lower than the percentage similarity in protein.
Answer:
Synonyms in the genetic code exist and some species only use one synonym to get the same amino acid. The reason why the percentage is low in gene is because it does not involve a lot of processes compared to the proteins which undergo mRNA and tRNA to be coded as amino acids.
