Match the body cavity type to its proper description. - Coelomate - Pseudocoelomate - Acoelomate - Coelom A. A fluid or air-filled space between the digestive tract and the outer body wall. B. Completely lacks a body cavity between the digestive cavity and outer body wall. C. Has a body cavity lined by tissue derived from the mesoderm and by tissue derived from the endoderm. D. Has a body cavity completely lined by tissue from the mesoderm. E. Germ Layer
Answer: A. A fluid or air-filled space between the digestive tract and the outer body wall. - Coelom
B. Completely lacks a body cavity between the digestive cavity and outer body wall. - Acoelomate
C. Has a body cavity lined by tissue derived from the mesoderm and by tissue derived from the endoderm. - Coelomate
D. Has a body cavity completely lined by tissue from the mesoderm. - Pseudocoelomate
E. Germ Layer- Coelomate
Explanation:
Coelom is a fluid filled body cavity which stores food, blood like fluid in it in some animals.
Those organisms which do not possess the body cavity or coelom they are called as acoelomate. Example, Platyhelminths
Those animals which have a body cavity derive from the germinal layers ectoderm, endoderm, and mesoderm are coelomate. Example, Annelids
Those animals which have scattered pouches which are not lined by all germinal layers instead one mesoderm will not be able to form coelom. These are called as pseudocoelomate. For example, Nematodes.

Explanation:
Two pea plants heterozygous for the characters of pod color and pod shape are crossed. Assume that G allele stands for green pod color, g allele−for yellow pod color, I allele−for inflated pod shape, and i allele−for constricted pod shape. Complete the Punnett square for this cross.
Answer:
Please find the punnet square in the attachment section
Explanation:
This question involves two different genes; one coding for pod color and the other for pod shape. The allele for green pod color (G) is dominant over the allele for yellow pod color (g) while the allele for inflated pod shape (I) is dominant over the allele for constricted pod shape (i).
According to this question, two pea plants heterozygous for both of the characters or traits are crossed i.e. GgIi × GgIi. Each heterozygous parent will produce the following possible gametes:
GgIi - GI, Gi, gI and gi.
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
- Green, inflated pods (G_I_) = 9
- Green, constricted pods (G_ii) = 3
- Yellow, inflated pods (ggI_) = 3
- Yellow, constricted pods (ggii) = 1

A consistent response in many organisms to changing environmental temperatures is the restructuring of cellular membranes.In some fish, phosphatidylethanolamine (PE) in the liver microsomal lipid membrane contains predominantly docosahexaenoic acid, 22:6 at C-2 of the glycerol-3-phosphate backbone and then either a saturated or monounsaturated fatty acyl group at C-1. Which of the following statements are False?
a. At 10 degrees Centigrade a lower percentage of PE molecules contain saturated fatty acyl groups at C-1 when compared to fish acclimatized at 30 degrees Centigrade.
b. At 10 degrees Centigrade a higher percentage of PE molecules contain saturated fatty acyl groups at C-1 when compared to fish acclimatized at 30 degrees Centigrade.
Ñ. At 30 degrees Centigrade a lower percentage of PE molecules had monounsaturated acyl groups at C-1 compared to that observed at 10 degrees Centigrade.
d. At 30 degrees Centigrade a higher percentage of PE molecules had monounsaturated acyl groups at C-1 compared to that observed at 10 degrees Centigrade.
e. The purpose of membrane restructuring with a change in temperature is to maintain fluidity of the membrane.
Answer:
The false statements are :
b. At 10 degrees Centigrade a higher percentage of PE molecules contain saturated fatty acyl groups at C-1 when compared to fish acclimatized at 30 degrees Centigrade.
d. At 30 degrees Centigrade a higher percentage of PE molecules had monounsaturated acyl groups at C-1 compared to that observed at 10 degrees Centigrade.
Explanation:
The false statements are :
b. At 10 degrees Centigrade a higher percentage of PE molecules contain saturated fatty acyl groups at C-1 when compared to fish acclimatized at 30 degrees Centigrade.
d. At 30 degrees Centigrade a higher percentage of PE molecules had monounsaturated acyl groups at C-1 compared to that observed at 10 degrees Centigrade.
Reason -
When temperature decreases, the proportion of unsaturated fatty acids increases and saturated fatty acids decreases that also decreases the fluidity of the membrane and thereby make it stiff.
When temperature increases, the proportion of unsaturated fatty acids decreases and saturated fatty acids increases that makes the cell membrane more fluidic.
So, the temperature changes restructures the membrane with respect to fluidity of membrane.
Therefore,
At 10° Celsius, at C-1 of glycerol, the proportion of unsaturated fatty acids increases and saturated fatty acids decreases.
At 30° Celsius, the proportion of unsaturated fatty acid decreases and saturated fatty acid increases.
A population of raccoons is thought to be in Hardy-Weinberg equilibrium for a tail-length gene. The frequency of the dominant allele (long tails) is 0.8. When a certain forest was surveyed, the scientist was able to tag 25 animals, which were all long-tailed. Does the lack of short-tailed animals suggest that the population is out of Hardy-Weinberg equilibrium in this forest?
A. Yes, because the survey shows 100% AA individuals, so the short tils must have been selected against.
B. No, because you would only expect 4 of the surveyed racoons to be short-tailed, so they may have been missed by chance.
C. Yes, because 20% of the surveyed raccoons should have been short-tailed.
D. No, because you would only expect 4% of the raccoons to be short-tailed, so they may have been missed by chance.
Answer:
D. No, because you would only expect 4% of the raccoons to be short-tailed, so they may have been missed by chance.

How does natural selection affect populations?
Answer:
Over time, these advantageous traits become more common in the population. Through this process of natural selection, favorable traits are transmitted through generations. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species.
Explanation:
1. What do you understand by the resolution or resolving power of a lens?
Answer:
The resolving power of an objective lens is measured by its ability to differentiate two lines or points in an object. The greater the resolving power, the smaller the minimum distance between two lines or points that can still be distinguished. The larger the N.A., the higher the resolving power.

What does "fishing down the food web" mean?
Answer:
Fishing down the food web is the process whereby fisheries in a given ecosystem, "having depleted the large predatory fish on top of the food web, turn to increasingly smaller species, finally ending up with previously spurned small fish and invertebrates".
PLEASE HELP! huntington’s disease (HD) is prevalent South Africa. Most of the families with HD have Dutch or British ancestry, which suggests they inherited the European HD allele. HD is believed to have first arrived in South Africa more than 300 years ago when Dutch colonists settled into the Western Cape in the 1600s. Thus, the prevalence of HD in South Africa is the result of the founder effect.
Mutations in the HTT gene cause Huntington’s disease. The HTT gene provides instructions for making a protein called huntintin. This protein plays a role in nerve cells in the brain. The HTT mutation that causes HD involves a DNA segment known as a CAG trinucleotide repeat. This segment is made up of a series of three DNA building blocks that appear multiple times in a row. Normally, the CAG segment is repeated 10 to 35 times within the gene. In people with HD, the CAG segment is repeated 36 to more than 120 times. An increase in the size of the CAG segment leads to the production of an abnormally long version of the huntintin protein. This causes the dysfunction and eventual death of neurons in certain areas of the brain. The more repeats, the more serious the disease is.
HD is inherited in an autosomal dominant pattern. There is both an adult onset (after reproductive age) and a juvenile onset pattern. People with adult onset typically have 40 to 50 repeats, while people with the juvenile form tend to have more than 60 repeats. Individuals who have 27 to 35 repeats do not develop HD, but they are at risk of having children who will develop the disorder. As the gene is passed on to offspring, the size of the repeat may lengthen into the range associated with HD.
Predict what will happen to the allele frequencies for Huntington’s disease in South Africa if there were a new mutation to the HTT gene that causes a reduction to the CAG trinucleotide repeat. Justify your prediction with evidence. Your response should include links to the sources of information gathered.
Answer:
If there were a new mutation to the HTT gene that causes a reduction to the CAG trinucleotide repeat, the allele frequency for Huntington's disease would decrease in South Africa. HD is caused by too many repeats of the CAG segment causing an abnormally long version of the huntintin protein which becomes deadly. so if the number of repeats is reduced then the person is more likely to not have Huntington's disease. If they do still develop Huntington's disease, it will be more likely to be adult onset and they will still have an opportunity to reproduce offspring which may carry the trait for reduced CAG.
