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.
The first one, ii. Natural selection and the formation of inseticide resistant insects or antibiotic resistant bacteria.
This can be explained in very simple way. As we all know, natural selection works in a way that only that adapted living beings are going to survive through a specific environment, whether it's because they can grab their food without too much work, or even that they can adapt to the weather. When we use inseticide, we are killing lots of non-resistant insects, and what's left are those that are resistant to this inseticide, and they'll reproduce again, and again we'll go through the same process, but remember, this insect is now stronger and more resistant that before.
The second case, iii. speciation and isolation give three examples how it may occur.
Well. the allopatric speciation and isolation will happen when theres a geographic barrier between one species. This one then is divided into two diffent habitats, but what can divide than could be a mountain, a tree, a river, a rock, anything. And this could be too called as a geographic isolation, because in this new environment, species are going to develop in a different way.
Answer:
In trees, most savanna adaptations are to drought--long tap roots to reach the deep water table, thick bark for resistance to annual fires (thus palms are prominent in many areas), deciduousness to avoid moisture loss during the dry season, and use of the trunk as a water-storage organ (as in baobab).
Answer:
An artificial cell or minimal cell is an engineered particle that mimics one or many functions of a biological cell.
