An acquired trait<span> is defined as a characteristic or </span>trait<span> that produces a phenotype that is a result of an environmental influence. </span>Acquired traits<span> are not coded for in the DNA of an individual and therefore cannot be passed down to offspring during reproduction
So the answer is </span><span>D. An acquired trait is developed during one’s lifetime.</span>
Answer:
It has 3 main functions
1.Sensory. The sensory function of the nervous system involves collecting information from sensory receptors that monitor the body’s internal and external conditions.
2.Integration. The process of integration is the processing of the many sensory signals that are passed into the central nervous system at any given time. These signals are evaluated, compared, used for decision making, discarded or committed to memory as deemed appropriate.
3.Motor. Sends a signal to the Corresponding effector then releases a hormone or moves a part of the body to respond to the stimulus.
Answer: D. allopatric; breakdown
Explanation:
Allopatric speciation is a type of speciation whereby individuals of the same biological population becomes separated up to the extent that there will no longer be gene flow between them.
The answer is B because:
Cell walls are made of cellulose and proteins (hence II).
Animal cells don't have cell walls (only cell membrane) but plant cells do so IV
They must be semipermeable since materials for example carbon dioxide and water for photosynthesis have to go into the cell <em>some</em> way.
Answer:
The factors which remained constant are as follows -
- material used as the membrane
- amount of substances used
- number of trials
The factors which have shown variation are as follows -
- molecule size (large starch molecules vs. small glucose molecules)
- whether the molecules diffused through the membrane (tubing)
Explanation
Some factors with in the experiments remained constant from the point of starting of the experiment to its end. While some factors were varied to study its impact on the experiment rate of progression or on the final product formed. Thus , out of the following given factors, the ones that remained constant are -
- material used as the membrane
- amount of substances used
- number of trials
The factors which have shown variation are as follows -
- molecule size (large starch molecules vs. small glucose molecules)
- whether the molecules diffused through the membrane (tubing)
