This dispersal reduces the likelihood that a sperm will find an egg. Many sperm and eggs die before achieving fertilization. The low success rate of external fertilization puts animals at a reproductive disadvantage compared to internal fertilization.
Answer:
The correct answer is: C) sodium, calcium, potassium, and chloride.
Explanation:
Minerals are of key importance for our bodies to function properly, which is why a balanced diet is always suggested for us to be healthy. The minerals that aid transmission of nerve impulses and provide for optimal muscle contraction are sodium, calcium, potassium, and chloride (coincidentally, all of these essential minerals can be found in milk; other sources include: meats, vegetables, fruits and legumes).
Answer:
Molecular, Microscopic, Cell, Tissue and Organ levels
Explanation:
The natural strength production needed for skeletal muscle to function occurs at the molecular level. You can develop a better knowledge of the properties of cells and tissues by simply studying the molecular systems common to the cells in question. The different muscular level down to myofilaments are:
-
Molecular level — actin and myosin
- Microscopic level — sarcomere and myofibrils
- Cell level — myoblasts and myofibers
- Tissue level — neuromuscular intersections and fascicles
- Organ level — The key skeletal muscles of the body
More genetic variation in the offspring, so the species can adapt to new environments because of this.
<span>C. Cells, Tissues, Organs, Organ Systems
The answer is C. Cells are the fundamental unit of life. Without them, life would not possibly exist. Well that is according to the cell theory, which states that cells are the basic unit of life, cells came from pre-existing cells and cells make up living organisms.
