12. Which of the following best explains how meiosis, followed by fertilization, ensures genetic variation?A. Changes in an orga

nism's DNA during prophase creates different versions of alleles. Reshuffling of the alleles during sexual reproduction produces the same allele combination as the parent and results in each member of a sexually reproducing population having a unique combination of traits.B. Changes in an organism's DNA during prophase I creates different versions of alleles. Reshuffling of the alleles during sexual reproduction produces variation that results in each member of a sexually reproducing population having a unique combination of traitsC. Changes in an organism's DNA during telophase creates different versions of alleles. Reshuffling of the alleles during sexual reproduction produces variation that results in each member of a sexually reproducing population having a the same combination of traits.D. Changes in an organism's DNA during telophase I creates different versions of alleles. Reshuffling of the alleles during sexual reproduction produces variation that results in each member of a sexually reproducing population having a unique combination of traits.

Those changes in an individuals' genotype that ensure genetic variation begin to be done in Metaphase, where chromosomes are aligned to the equatorial axis of the cell, and eventually, each chromosome is pulled to each pole of the cell during Anaphase I. After this process, follows telophase I, where we can say that each chromosome is given to each of the two daughter cells. We can say then that the creation of different versions of alleles begins with Telophase I.

The ph of the water in several lakes in norway and sweden had decreased to below 5.0 due to an increase in acid rain. What is mo
arsen [322]

Answer:

What will most likely happen in these lakes is that there will be a decline of several fish populations. The correct answer is A.

Explanation:

The options attached to the question are given below:

A. The decline of several fish populations

B. An increase in the number of fish.

C. An increase in the number of primary producers.

D. Increased predator- prey relationship.

The fishes, just like any other living organisms has ideal body temperature and pH at which they act best. The ideal pH for fish living in lake water is between 6 and 8. If the pH is reduced below this value then the water will become acidic and this will be toxic for the fish population living in the lakes. Therefore, those fish that can not cope will die and there will be a decrease in the fish populations.

Which statement describes a common measurement error?
Kitty [74]
Answer – C (Using instruments that have not been calibrated).

When the integrity of an instrument’s calibration has been compromised (usually due to exposure to a shock, vibration, or physical damage), it needs to be calibrated; failure to do this inevitably leads to inaccurate measurement; this is a very common measurement error.

Which area of the human cortex is most different from the brains of other animals?
maxonik [38]
Cerebral cortex is the area of human cortex that is different from the brains of other animals. Cerebral cortex functions is responsible for the thinking and taking in information in order to make a necessary action based on the perception that it receives. Cerebral cortex are divided into 4 lobes with a different function namely; frontal, temporal, parietal and occipital which are converts the sensory information that you receive.<span />

Inga [223]

Answer:

<em>The correct option is B) Scientific paradigm</em>

Explanation:

The scientific paradigm focuses on the infection and the microorganism for the occurrence of the infection. A scientific paradigm also refers to the treatment of these infections through pharmaceutical or surgical approaches. Hence, option B is correct.

Other options, like option A, is not correct because a holistic paradigm focuses on the connection between the mind, body and the soul. Option C is false because the analytical paradigm is not a part of the major health belief system.
