Answer:
Rapid increases in water temperature cause extensive fish kills
Explanation:
Biotic factors are all living organisms that contribute to an ecosystem. On the other hand, abiotic factors are non-living factors, such as climatic factors (temperature, rainfall, wind), edaphic factors (soil type, soil texture, soil aeration etc). Changes of abiotic factors can have a huge influence on living organisms of ecosystem. The effects might be benefical or harmful.
Some of the most common abiotic factors that can impact a marine ecosystem are water temperature, currents, light, alkalinity, oxygent concentration etc.
Answer:
Lower gravitational force due to lower mass.
Explanation:
Mars has lower gravitational force than Earth because of its lower size because mass has a direct effect on gravitational force of an object. Earth has mass of 5.972 × 10^24 kg which is 10 times greater than mass of Mars which is 6.4171 x 10^23 kg. So due to earth's more mass, it has more gravitational force than planet Mars which has lower mass than earth.
To answer this specific question,

you would like, feel free to ask another question.
1.
Anaphase. In <span>Anaphase the sister chromatids separate from each other to the opposite sides of the cells.
2. </span>
Chromosomes would not separate into two nuclei. <span>Mitosis is a process cell division, where one cell divides into two identical cells.
</span>
3.
Metaphase I. <span>Meiosis prophase I is the phase in which chromosomal crossing over occurs. The phase after prophase I is metaphase I.
4. </span>
Its body cells would have 36 chromosomes, and its gametes would have 18 chromosomes. <span>In the gametes, there are half of the number of chromosomes present in the body cell.
5. </span><span>
A species has to adjust rapidly to a changing environment. To adjust to the environment, crossing over is necessary, and it does not occur in mitosis, but meiosis.
6.
50 percent. Parents: Yy x yy
Offspring: Yy Yy yy yy
50 % is Yy and 50% is yy.
7. </span><span>
One parent had white eyes and the other was heterozygous for eye color. The ratio in the offspring is 50-50. The only possibility is the following:
Parents: Rr x rr
Offspring Rr Rr Rr Rr
8. </span><span>
Their fur will be a mixture of red and white hairs. The offspring will be heterozygous. They will have alleles for both red and white hairs and both will be expressed.
</span>
9. Not enough information.
10. <span>
Both of the parents' genotype must have been Pp. The genotype of the white plant is pp since it is recessive:
Parents: Pp x Pp
Offspring: PP Pp Pp pp
One of the four is white.</span>
