C. A new ray will grow back in its place.
Answer:
4
Explanation:
A carbon atom can form covalent bonds with four hydrogen atoms because each hydrogen atom needs one electron to achieve stability. We know that carbon atom has four electrons in its outermost shell so four hydrogen atoms are needed to get stability to both carbon and hydrogen. If there is another atom that needs two electrons to attain stability so the carbon atom can form bond with two atoms because no extra electron is available for pairing.
Co-transport system of intestinal epithelial cells. Glucose then moves into the blood through the permease in the membrane between the cell and the blood. Thus, ATP is used as an energy source to drive Na+ out of the cell, resulting in glucose transport from the intestine to the blood.
Answer: The correct sequence in the expression of a trait is gene > protein > trait (Option B).
Explanation:
During gene transcription, a linear fragment of DNA referred to as a 'gene' is used as template to synthesize a complementary messenger RNA (mRNA) sequence.
Subsequently, this mRNA is then used as template to create a protein by a process called translation.
Moreover, phenotypic traits can be defined as all observable characteristics that an organism has.
The phenotypic traits are largely determined by the expression of either enzymatic or structural proteins, which interact to shape the phenotype of an organism.
In conclusion, the correct sequence in the expression of a trait is gene > protein > trait (Option B).
This type of speciation is called Peripatric Speciation. Peripatric speciation gives rise to daughter species that becomes reproductively isolated. Parent and daughter species are usually adjacent to each other but did not overlap. There are two requirements for this kind of speciation, geographic space and time.
