Answer:the big birds survived
Explanation:
Answer:
A. Dominant alleles often encode functional products, whereas recessive alleles often do not encode functional products
Explanation:
One gene can have it's variant forms called allele but in one individual only two allele form of a gene can be present. These two allele form can be the same(homozygous) or different(heterozygous). A dominant allele often encode a function protein of product while recessive allele often code for non- functional product.
Therefore when the dominant allele is present in the chromosome then function products are formed which can be seen in the phenotype and even a single dominant allele produce the functional product like in heterozygous condition so phenotype in heterozygous and homozygous dominant condition appears same. So the correct answer is A.
If the facts about proton pumping are true, then protons are pumped into the matrix of the mitochondria.
<h3>What causes the electron transport chain's proton pumping?</h3>
Proton pumps are found in the electron transport chain's complexes I, III, and IV. The complexes absorb the energy generated when electrons migrate energetically downward and use it to pump H +start superscript, plus, end superscript ions out of the matrix and into the intermembrane gap.
<h3>when outside of the Matrix are protons pumped?</h3>
At complexes I, III, and IV, the matrix is pumped of protons (2 per complex). The resultant proton gradient drives ATP synthesis: 2 H+ are generated for every ATP. The inner mitochondrion is charged differently due to the proton gradient.

Answer:
1) pathway taken by water
water is absorbed from the soil, through the root hair cells and is transported by the xylem vessel up the stem to the leaf and/or flowers. From the leaf, some water is lost to the atmosphere as vapors escape out through the stoma present in the lower epidermal layer of the leaves.
2) water potential gradient
water potential refers to the concentration of water present. A gradient forms when there is a difference between the concentrations of water in two regions separated by a partially permeable membrane.
Hence, water moving down a water potential gradient means that it goes from a region of high water potential to a region of low water potential.
3) There are tiny openings on the lower side of the leaves called as stomata (plural: stoma) that allow for gaseous exchange to occur. These openings are controlled by guard cells which are open during the day and close during the night.
Hope that answers the question, have a great day!
