Insects that go through three stages of change in their life cycle have an incomplete metamorphosis while complete metamorphosis has four stages. The first stage of incomplete metamorphosis is the egg. During this time, the insect will hatch into a form called a nymph.
Answer:
The correct answer is - option a. It should be testable in a valid period of time
Explanation:
A thought that presents a temporary clarification about a phenomenon observed by a scientist is a hypothesis. The fundamental highlights of a good scientific hypothesis are: testability and falsifiability
A testable scientific hypothesis should answer the logical question. This is one that can be checked valid or bogus utilizing the information gathered or the experience gained.
a good scientific hypothesis must be testable and falsifiable. We should have the option to test the hypothesis utilizing the techniques for science and in the event that you'll review Popper's falsifiability rule, it must be conceivable to accumulate proof that will disconfirm the theory on the off chance that it is surely false.
Thus, the correct answer is - option a. It should be testable in a valid period of time
D. Plants have adapted to deal with the sun in many different ways, and this is one. The stomata are regulated by guard cells, which are activated by different things depending on the species of plant, and guard cells are supposed to keep the stomata from staying open all the time and losing too much water to evaporation. So, the solution is to have the stomata on the bottom of the leaf to prevent direct sunlight contact (and therefore more evaporation), and guard cells to protect the stomata.
The name comes from a latin word meaning to glue or bind together. DNA ligase catalyses the joining of DNA fragments (usually those produced by restriction enzymes). Thus different genes can be put into vectors and moved into other hosts.
Resource partitioning
Resource partitioning refers to differences in resource use
between species regardless of the origin of the differences. Similar species
can coexist in the same ecological community without one pushing the others to
extinction through competition. Species compete for the same resources which
include nutrients and habitats which are the raw materials needed by organisms
to grow, live, and reproduce. For the question given above, the divergence in
lizards is an example of resource partitioning.
