Answer:
See explanation:
Explanation:
Humans are the same, one side to the other. The human body is a mirror image, one side to the other. The cnidarian phylum does not necessarily have bilateral symmetry. Body forms like jelly fish, sea anemones, and coral are examples of cnidarians. Note that jelly fish may be somewhat symmetric, but not totally and not in the same way that the human body is.
Gross motor - controlling the head, sitting, crawling, maybe even starting to walk. Fine motor - holding a spoon, picking up a piece of cereal between thumb and finger. Sensory - seeing, hearing, tasting, touching and smelling. Language - starting to make sounds, learning some words, understanding what people say.
Answer:
B. The prefixes chemo- and photo-: define the electron source
Explanation:
The prefix chemo is related to <u>chemical/drug</u> and photo is related to<u> light</u>. This can be proved by analysing the following examples:
Chemotherapy = therapy with chemicals
Phototherapy = therapy with light
The choices can be found elsewhere and as follows:
1.are soluble and can easily pass through cell membranes
<span>2.contain long chains of amino acids and fatty acids </span>
<span>3.contain atoms of carbon, hydrogen, oxygen and nitrogen </span>
<span>4.are a direct result of dehydration synthesis
</span>
I believe the correct answer is option 1. When most proteins, fats, and carbohydrates are digested completely, they are converted to end products that are soluble and can easily pass through cell membranes. So as to distribute the nutrients needed in different parts of the body.
Answer: B. Poorly adapted individuals never produce offspring
Explanation:
Natural selection is a theory that states organisms adapts to its environment due to differences in their phenotypes. So, <u>individuals with favorable traits are more likely to survive and reproduce</u>. It is a key mechanism of evolution, which is the change in traits of a population over generations.
<u>Populations respond to natural selection if they contain heritable variation </u>among them, wich means that individuals differ in the traits they transmit to their offspring.
Because of the environmental selection pressures, individuals produce more offspring than their environment can support. <u>The pressure determines which individuals will survive and reproduce</u>, while others will die because of predation or diseases. So, natural selection is based on the observations of adapted individuals.
