Answer:
Based on this, you know that Sampson is using the whistle as a <u><em>secondary </em></u> reinforcer to train the dolphins.
Explanation:
Secondary Reinforcement can be described as a condition in which a stimulus initiates a behavior after being previously associated with a primary reinforcer. A secondary reinforcement is a stimulus that satisfies basic survival instinct such as food, drinks, and clothing.
The same phenomenon was being used by Samson to train his dolphins to perform tasks. The dolphins enjoyed the sound of the whistle because previously that sound was paired to them getting their food.
<span>If a population is not in Hardy-Weinberg equilibrium that can cause deviations from expectation depending on the assumptions of HW that are violated. If a population violates some of the assumptions (like mutations, migrations and selection) the allele frequencies will change over time. Also, if a non-random mating occurs (like inbreeding), it will cause an increase in homozygosity for all genes.</span>
Answer:
Explanation:
This is because meoisis division occurs in gamates which are sperm cell and egg cell . And in meoisis division the number of chromosomes for the daughter cells is half the number of chromosomes that the parent cell have. This is because when there is a fussion of male and female sex cells ,the zygote which is the daughter cell should have the 46 chromosomes which is the normal chromosomes for humans and when this chromosomes are in pairs then they should be in 23 pairs of chromosomes which are haploid and later be used for another cycle when the person matures and ready to reproduce
Mutualism, The question is asking us to choose the correct symbiotic relationship.
There are THREE types of Symbiosis.
SYMBIOSIS is a relationship between two organisms.
I'll give you a quick run-through of each one.
1. MUTUALISM is where both organisms benefit, from one another.
2. COMMENSALISM is where one organism benefits, and the other is totally unaffected.
3. PARASITISM is where one organism benefits, while the other is harmed.
