Haploid and diploid chromosomes are two types of chromosomes present in cells. Then, both have differences with regard to the number of chromosomes. Of course, the number of chromosomes in the cell content.
Chromosomes are double helix structures, which then accommodate the DNA and proteins present in the cell. In other words, chromosomes are strands of DNA chains containing the genes in living organisms. Then as a container for DNA and cell protein.
Furthermore, it will help in packing DNA. There is a long homologous chromosome with a centromere position and the staining pattern is the same as the gene in the appropriate location characteristics.
The best answer would be the first statement. The first sentence which is 'water pollution causes a decrease in fish populations in a river.' illustrates how human <span>activities can most directly change the dynamic equilibrium of an ecosystem.</span>
Answer:
A downhill
Explanation:
A runoff happens when water drags sediment from a rock over a sloping terrain. Thus, water drags the eroded fragments of a rock in favor of gravity, pushing these fragments downwards. This is very common in mountainous and steep regions, without vegetation cover, where erosion caused by runoff is very high.
The Core Makes The Magnetic Field Around The Earth
Answer:
polyphyletic
Explanation:
Polyphyletic
The organisms in this groups show similar attributes, but lack a recent common ancestor and could have risen from convergence.
Take for instance, birds and mammals in a polyphyletic group of warm-blooded animals may possess a mixture of biochemical and physiological attributes. On the other hand, their most recent common ancestor was a cold-blooded species, which shows birds and mammals had their warm-blooded nature as separate groups.
Another example is the Elephants, hippopotamuses, and rhinoceroses belongs to a polyphyletic groups with each one coming from a separate small species.
