Answer:
Cells must divide to perform functions such as growth of the organism, replacement of damaged or old cells, and asexual reproduction in some organisms.
Explanation:
Answer:
A. Fish need light to see their food
Explanation:
B is incorrect because fish take in oxygen constantly to respirate. If they only took in oxygen when it was dark they would die.
C is incorrect because expelling CO2 is also a constant process as a part of the reactions that take part inside living organisms, so it happens constantly (a bit like B)
D is incorrect because plants need light for food (photosynthesis) and would most likely die or have stunted growth if left in the dark.
A is correct because when it is dark, fish rely on other senses to find food as most fish cannot see as well in the dark, therefore when they have light they can see their food more easily.
Hope this helped!
Answer:
generation 1
Explanation:
The allele frequency is a term that represents the frequency that an allele can appear in a given population. This term can help to develop conclusions about the genetic diversity that a region presents in relation to the individuals that compose it.
In relation to the question above, generation 1 had the highest frequency of having one of each allele. This is because this generation presents the maximum frequency of the dominant and recessive alleles in a coherent way, 0.60 and 0.40. However, the other generations showed a steady and progressive decrease in the recessive allele.
Im not sure if this is right or not but i think it might be C.
Hope its right!!!!
Answer: Nondisjunction means that a pair of homologous chromosomes has failed to separate or segregate at anaphase so that both chromosomes of the pair pass to the same daughter cell. This probably occurs most commonly in meiosis, but it may occur in mitosis to produce a mosaic individual.
