Answer:
B
Explanation:
According to Mendel, an organism receives two forms of a gene from each parent. This form received by each parent is called an ALLELE. An allele is the variant form of a gene for a particular trait.
For a diploid organism, two copies of genes (alleles) are acquired by an organism. The combination of these alleles from each parent determines the genotype for that gene.
In Mendel's experiments, he discovered that one allele can mask the expression of another for a trait. He called the allele that masks DOMINANT allele while the allele that is masked RECESSIVE allele. The combination of these alleles, whether two dominant or two recessive called HOMOZYGOUS or one dominant and one recessive called HETEROZYGOUS, determines the phenotype of the organism for that gene.
N.B: There are exceptions to this pattern of inheritance.
Answer:
The exact terminology would be motion sickness, not car sickness.
Explanation:
Reading a book or using your phone while in or on any moving object can cause motion sickness.
With motion sickness your body is moving in space, such as in a moving car or on a boat rocking at sea, but your eyes aren’t getting the same information. Kind of like when you are reading while in a car: Your eyes are focused on the words, thinking you’re stationary, but the rest of your body is sensing the movement of the car.
Motion sickness is basically a sensory conflict.
Now there is something called cybersickness, which is almost the same as motion sickness but it pertains more to using/ watching moving pictures on a screen while your body is stationary.
It has opposite sensory effects than motion sickness, where your eyes think you are moving but your body is not.
Parasites benefit their hosts is the true statement. Parasitism is a symbiotic relationship in which one organism (the parasite) benefits from another organism and this other organism is harmed by the parasite.
The others aren't true because:
- the organism that is harmed doesn'y adapt and evolve it still is vulnerable
- it is a fact that parasites change from hosts
- phoresy is an association between two species in which one transports the other. This does not include killing the host (is possible, but it is not a condition under which you can call something a phoresy).
Edward Jenner inferred that a person who once had small pox cannot have it once again. So something is there in these persons which grows after the initial infection which interferes with the secondary infection resisting it.
<h3><u>
Explanation:</u></h3>
Edward Jenner is called the Father of Vaccination. Jenner noticed that the milkmaids who deal with the cows all the time don't generally suffer from the cowpox or small pox. Then as an Experiment, he took some sample from the pustules of the cow having pox and then cleaned it and injected the sample into a healthy child. Then when everyone of the locality suffered from the same disease, that child remained healthy. So that lead to infer that there are something in the pustule which lead to resist the secondary infection of this disease. So this lead to the invention of vaccines.

it depends but a good way u could figure it out is look it up online and then if u still not sure come back and ask if that answer is right
