B. They decrease. As more we use the sources of nature, the less is left.
Answer:
sporopollenin
While the exine is composed of sporopollenin, a complex and highly resistant biopolymer containing fatty acids, phenylpropanoids, phenolics and carotenoids, the intine is largely composed of pectin and cellulose.
Explanation:
Answer and Explanation:
A gene is a section of DNA. The change in the sequence of the DNA is known as mutation. Mutation always changes the sequence of the DNA. Sunlight can cause mutation. Sunlight produces structures named thymine dimers. Thymine dimers produce twist in the shape of DNA. These twists make DNA hard to copy, which can lead to mutation. It is essential to use sunscreen to block UVA and UVB rays to prevent thymine dimers from emerging in our cells. The US Food and Drug Agency recommends an SPF (sun protection factor) to defend against skin aging and skin cancer. X-ray radiation is a form used in x-rays. The energy level of the X-ray radiation is very high that can produce free radicals. Free radicals can steal electrons from DNA that can cause mutation. By using medical images, we can decrease exposure to X-rays. Less exposure to X-rays prevents mutation and also prevents the production of gene protein in other body parts.
The right option is Courtship
Courtship is a behavior in which different
species interact and select their partners for mating which leads to
reproduction. Most times, the female specie chooses the desired male to mate with before
copulation. Various behaviours such as display
of strength, dancing and vocal utterance are often used during courtship. For the question given above,<span>the type of behavior displayed by the species of balloon flies is an example of courtship.

I hope that this is the answer that you were looking for and it has actually come to your desired help.</span>
