Some man-made fibres, too, are derived from naturally occurring polymers. For instance, rayon and acetate, two of the first man-made fibres ever to be produced, are made of the same cellulose polymers that make up cotton, hemp, flax, and the structural fibres of wood.
Is this supposed to be a true false question?
Sexual reproduction is the process in animals that requires meiosis to take place. It does not matter whether the animal is single celled or multi celled. Meiosis is the type of cell division in which four daughter cells are formed with half the number of chromosomes of the original orthe parent cell. The perfect example of meiosis is the formation of gamets and spores. Meiosis is the process that helps in the formation of male and female reproductive cells like the sperm and the eggs. Meiosis is totally different from mitosis.
Answer:
If tan A = 3 / 5, then sin A = 3√34 / 34 and cos A = 5√34 / 34 .
Assuming x = 5 and y = 3 (The problem is deficient in this regard)
5(3√34 / 34) + 3(5√34 / 34)
30√34 / 34
15√34 / 17
Explanation:
I hope this helps!
<h2>Adaption of genes to improve survival</h2>
Explanation:
- People include varieties inside their heritable characteristics. A few varieties improve an individual fit to endure and replicate in their condition.
- In the event that this proceeds over ages, these ideal adjustments (the heritable highlights that guide endurance and multiplication) will turn out to be increasingly more typical in the populace.
- The populace won't just advance (change in its hereditary cosmetics and acquired characteristics), yet will develop so that it gets adjusted, or more qualified, to its condition.
- The adjustments or changes in conduct, physiology, and structure of a life form to turn out to be increasingly fit to a domain. As per Charles Darwin's hypothesis of development by normal choice, living beings that have heritable characteristics that empower them to all the more likely adjust to their condition contrasted and different individuals from their species will be bound to endure, replicate, and give a greater amount of their qualities to the people to come.
- Hence, the correct answer is "Individuals adapt their genes to improve survival".
