Answer:
c. a proton gradient set up across the thylakoid membrane
Explanation:
During the photosynthesis (this also occurs in cellular respiration in mitochondria), hydrogen ions (H+) move across the thylakoid membrane down their electrochemical gradient (from the area of their higher concentration to the area with hydrogen ions lower concentration). An ion gradient can be used for the production of ATP.
Answer:
Phenotype is physical appearance of the individual while genotype is the genetic makeup of the individual.
Explanation:
Two parents having normal phenotype but effected individual is due to the parents may be Carrier for the particular deseis and the gene responsible for the desies may be in recessive form and the parents are not effected. The gene is not present in dominant form and can not show its effect but the parents are not effected and the daughter may be affected by certain desiese.
A snow-covered mountain has a higher albedo than a dark-colored corn field. Therefore, it will reflect solar energy <u>more</u> than the field.
<h3 /><h3>Does snow have a high or low albedo?</h3>
Dark surfaces absorb the rays from the sun (low albedo). Ice- and snow-covered areas have high albedo, and the ice-covered Arctic reflects solar radiation which otherwise would be absorbed by the oceans and cause the Earth's surface to heat up.
<h3>Why does snow have a high albedo?</h3>
Freshly fallen snow reflects incoming solar radiation very well and therefore has a high albedo. New snow typically has an albedo of 0.96 to 0.98 in the visible and near-UV range (Grenfell et al., 1994), and 0.8 averaged over the entire wavelength spectrum.

Answer:
a. 4. Belly
b. 6. Action
c. 1. Innervation
d. 3. Skeletal attachment
Explanation:
Skeletal muscle is a type of striated muscle which is under the control of the voluntary nervous system (SNS). These muscles (skeletal muscles) are attached to the bones by tendons so it is possible to use them in order to move the body. The movement generated by a muscle is known as its action. Skeletal muscles usually act in groups that together produce the coordinated motion of a joint. A muscle belly is a type of muscle that has a large mass of tissue in the middle of the muscle between the origin and insertion. Muscle contraction occurs when nerve impulses travel along the nerves to the muscles. An innervation can be defined as a measurable impulse from a nerve. A muscle is composed of motor units which are each constituted by only one neuron and muscle fibers that it innervates (a single neuron can innervate many different muscle fibers).
