<h2>Skeletal & Cardiac Muscle</h2>

Explanation:

  • A skeletal muscle is a contractile organ that is directly or indirectly attached to bone. Skeletal muscles move the body. Skeletal muscle contractions pull on tendons, which are attached to bones. If contraction of the muscle causes the muscle to shorten, the bone and, thus, the body part will move. For example, the biceps brachii is attached to the shoulder and the forearm bones
  • Contraction and, thus, shortening, of the biceps brachii pulls on the tendons attached to the bones. Skeletal muscle contraction, however, doesn't always result in the movement of a body part
  • Contraction of smooth muscles controlled by autonomic nervous system and contraction can be initiated by electrical or chemical signals. Actin is plentiful, lacks troponin
  • Skeletal muscle is controlled by somatic motor division and always begins with an action potential

Natural selection refers to all of the following EXCEPT
elena-14-01-66 [18.8K]

Answer:

Darwin proposed the theory of natural selection to explain the process of evolution. According to Darwin’s theory of natural selection, all organisms have the potential to reproduce limitlessly irrespective of the fact that each species maintain a constant density over time. However, the struggle for existence, i.e. the competition among individuals for available resources to survive and reproduce, put a check on species density (D) and maintains it at a constant level (B). Survival of fittest is unequal ability of individuals to survive and reproduce based on suitability of their inherited characters to prevailing environmental conditions (A). It imparts the reproductive advantage to certain organisms which account for major part of the gene pool of the species. Thus, natural selection favors the individual with survival and/or reproductive advantage over others under existing environmental condition (E). Thus, the correct answer is option C.

The mitochondrial matrix has what charge compared with the intermembrane space?
Solnce55 [7]
The matrix (inside mito) has a negative charge compared to the intermembrane space (outside of mito but still inside) because positively charged protons are constantly pumped from the matrix to the intermembrane space. A cell oxidizes an organic molecule producing 3 NADH molecules and 3 FADH2 molecules..
