Abiotic factors are the greater part of the non-living things in a biological community. Both biotic and abiotic factors are identified with each other in a biological community, and in the event that one component is changed or expelled, it can influence the whole environment. Abiotic variables are particularly vital on the grounds that they specifically influence how living beings survive.
Answer:
D. frictional, structural, and cyclical unemploment.
Explanation:
Types of Unemployment
There are three basic types of unemployment which are the cyclical, frictional, and structural.
Cyclical Unemployment
Is due to the highs and lows of the economy, as in cycles e.g in times of recession, the job lost is know as cyclical unemployment.
Frictional Unemployment
It results from the actual turnover in the labor market and the time taken to get a new job. E.g. when a worker change his/her job, it requires time to get a name job and learn more of the job in details for him/her to be called up for interview and get hired. This process is termed frictionally unemployed.
Structural Unemployment
Originates from a lack for demand for a specific class of worker due to the worker lacking the appropriate skills needed by the employee as this can cause the worker to lose the job. Another example is sourcing for a reduced cost of labour abroad.
Cells of the skin and digestive tract are continuously sloughed off and replaced by new ones due to mitotic division.
Some body parts of animals and plants can be regenerated by mitotic cell division.
Vegetative propagation in plants and budding in some animals also occurs due to mitosis.
<span>Controlled experiment is an experiment done under controlled conditions in which only one variable at a time is changed in order to isolate the results. An alternative to a controlled experiment would be a correlation study. A correlation study is a research method in which two variables are compared (what are the similarities and the difference between them). So, correlation study is a type of controlled experiment in which ove variable is changed and the dependence with another variable is analyzed.</span><span />
Answer:
number of sheep with homozygous dominant white fat genotype = 5399
Explanation:
If p = frequency of dominant allele and q= frequency of recessive allele
According to Hardy-Weinberg equilibrium:
p + q =1 and p² + 2pq + q² = 1
where p² = frequency of homozygous dominant genotype
q²= frequency of homozygous recessive genotype
and 2pq= frequency of heterozygous genotype
Here,
q² = 53/6520= 0.0081
q = √0.0081 = 0.09
p = 1-q = 1-0.09= 0.91
So, p² = 0.91² = 0.8281
number of sheep with homozygous dominant white fat genotype= 0.8281*6520 = 5399
