Answer:
a) Watch the attaccment
b) Ethyl bromide is more reactive than n-propyl bromid, and this more than neopentyl bromide. Ethyl bromide has less steric hindrance than the others, to SN2 reactions.
c) t-butyl bromide is more reactive than isopropyl bromide, and this more than ethyl bromide. t-butyl bromide structure stabilize the carbocation, better than the others.
Explanation:
Speed of SN2 reactions depends on steric hindrance, the less hindrance, the most reaction speed, meaning more reactivity. Then, those linear structures are more reactive to SN2 reactions.
In the other hand, speed of SN1 reactions depends on the stability of the carbocation formed. Structure with ramifications can stabilize better the carbocation, these structures are more reactive to SN1 reactions.
Adaptation is the characteristic of an organism that allows it to survive better in an environment
D. All of the given statements are true in context of animal cloning.
Explanation:
Cloning is the method in which a similar genetic copy is produced.
Animal cloning is a complex process in which an organism of similar type is produced with same DNA to each other.
Mostly successfully cloned animals in live are cattle,sheep,goats...
Scientists have also cloned rats,mice,rabbits,horses...
This animal cloning is used for farming by the farmers which gives acceleration in their crop production.
Animal cloning have showed some adverse affects in sheep, and other mammal animals regarding issues in their organs like liver,heart,brain etc.
The success rate is very low like 10% in animal cloning due to many reasons such as surviving from birth to the cloned animals.
Positive applications for allelotoxin is that it prevents plants from enduring any type of competition with other species.
<h3>What is Allelopathy?</h3>
This is the process in which a plant inhibits the growth of another through a secretion of a chemical which is referred to as allelotoxin.
This technique however reduces biodiversity which isn't ideal so as to prevent organisms from going extinct and also reduces adaptation or evolution due to the reduced or non growth of the plant species which are affected.
A common example is the sorghum plant preventing of the growth of weeds thereby resulting in the most appropriate choices for the positive applications of allelotoxin.
