The groups of small cells better than one large cell at moving material in and out because they have a greater surface-to-volume ratio.
<u>Option: A</u>
<u>Explanation:</u>
This happened so as these smaller cells, unlike bigger cells, can quickly and willingly enter and move through the membranes of other cell membranes and permeable coverings. For these smaller and mini cells, it is also important to penetrate and move effectively, distribute and transport products and materials such as nutrients, oxygen and waste across the body without requiring enough energy and saving less space. They are cheaper, more effective and use less room for simple reasons, and most notably deplete less resources.
Explanation:
Homologous chromosomes are two pieces of DNA within a diploid organism which carry the same genes, one from each parental source.
In simpler terms, both of your parents provide a complete genome. Each parent provides the same 23 chromosomes, which encode the same genes. So, our cells carry 46 total chromosomes, in two copies. However, each homologous chromosome can provide a different version of each gene. Two versions of each gene create more variety, lower the detrimental effects of negative mutations, and generally stabilize a population.

2 is correct all animals have a similar goal is survive and reproduce
The best way to prevent the growth of bacteria on food preparation surfaces is sterilization. Details about sterilization can be found below.
<h3>What is sterilization?</h3>
Sterilization is the process of treating something to kill or inactivate microorganisms.
Sterilization can also be done to prevent the reproduction of microbial population.
It is a known fact that microbes are responsible for food spoilage, hence, to prevent this, it is important to kill or get rid of them.
Therefore, the best way to prevent the growth of bacteria on food preparation surfaces is sterilization.

Around 100,000 years ago there was a second hominine species closely related to modern humans, Homo <span><span>neanderthalensis,</span><span> or commonly called the Neanderthal</span>.</span> Recent studies of neanderthal DNA have shown that there is 3-4% of their genes in modern humans outside of Africa, mostly from Europe, including the ones for adapting to the cold and vitamin D absorption.
