Answer:
coral reefs providing critical habitat and sources of food for tropical fish are slowly recovering, due to successful enforcement of fishing quotas
Explanation:
This is a wrong statement because coral reefs contrary to the statement is not recovering, Over-fishing an destructive fishing,(to meet up with increasing demand) are some of the human impacts reltively control by the enforcement.
But,acidification (eutrophication), and mass coral bleaching from global warming are not restricted by the enforcement of fishing quotas and are drastically reducing the population of the reefs.This in turn affecting the survival of the fishes, reducing the population,
Huntington’s disease: Huntington’s disease is a disease in which certain parts of the brain waste away; symptoms usually begin later in life. In a community in Venezuela, an allele for Huntington’s disease (represented by the letter H) is completely dominant to the allele for no Huntington’s disease (represented by a lowercase h). The three possible parental genotypes are HH, Hh, and hh. There are six possible crossings that can be made between these genotypes (for example, HHxHH, HHxHh, etc.). Show the probabilities of the genotypes and phenotypes in the F1 generation from all six possible crossings. In real human families, would you see offspring in proportions equivalent to these probabilities? Why or why not?
Answer:
Regarding Huntington's disease, it can be said that it is an inherited disease with an autosomal dominant character, so it is enough that one of the children inherits one of these characters to manifest this neurodegenerative disease, it is considered that the pattern is usually 50% of the total of children of sick parents can suffer it, however if both parents are carriers the number rises leading to 100% of the children affected, on the contrary if no parent has the dominant gene and are homozygous recessive, neither your children will suffer the disease
The possibilities are the following:
Parent 1, inheritance pattern: Hh * hh, the possible gametes for this cross-linking are H, H, h, h, offspring; Hh, Hh, hh, hh 50% of the children could be sick
Parents 2, inheritance pattern: hh * hh, the possible gametes for this cross-linking are h, h, h, h. the offspring will be; hh, hh. no sick child
Parent 3, inheritance pattern: HH * HH, the possible gametes for this cross-linking are H, H, H, H, the offspring will be HH, HH, all children may be sick, 100%
parents 4, inheritance pattern: Hh * Hh, the possible gametes for this cross-linking are h, H, h, H. the descendants will be HH, Hh, Hh, hh 50% of sick children
Parents 5, inheritance pattern: Hh * hh, the possible gametes for this interbreeding are H, h ,, offspring will be Hh all sick children
Parent 6, inheritance pattern: Hh * Hh the possible gametes for this cross-linking are H, h, the descendants will be Hh, the heterozygous descendants will have the disease.
Meiosis makes sperm and egg cells. In
humans, sperm and egg cells each have
chromosomes. Therefore a fertilized
human egg cell (sperm and egg cell
combined) would create a cell with
chromosomes.
The fertilized human cell will have 46 number of chromosomes, 23 from the sperm cells and 23 from the egg cell.
What is meiosis?Meiosis is a type of reproduction in which the parent cell divide into four daughter cells and each daughter cell are genetically different from the parent or have different number of chromosome from the parent.

A population of Anolis lizards lives on the mainland. During a storm, three groups of Anolis migrate to three islands, one large, one medium sized and one small Approximately 200 lizards establish on the small island, 2000 on the medium-sized island, and 20,000 on the large island. You may assume that:_____.
a. the lizards that initially establish on each island are, at first, representative of the mainland population.
b. the islands support these population sizes over time (so 10 generations later there are still just 200 lizards on the small island).
c. Rates of mutation are negligible (i.e. no mutation).
mating is random, and the effective population size is the same as the total population size. I. In the next generation, on which island will genetic drift be strongest?
1. Small island,
2. medium island,
3. large island
Explain: ii. After 10 generations which island would you expect to have the highest heterozygosity?
1. Small island,
2. medium island,
3. large island
Explain: iii. Some Anolis lizards on these islands have a dominant allele L1 that confers an improved ability to leap over allele L2 at the same locus. This difference in leaping ability causes selection to favor the L1L2 or L1L1 genotypes over L2L2 by about s = 0.002. Given this information, and the information above:
1. On the big island, Natural selection will make it more likely that the L2 allele is lost
2. On the big island, Genetic drift will influence the frequency of the L2 allele
3. On the small island, Natural selection will make more likely that the L2 allele will be lost On the small island, Genetic drift will influence the frequency of the L2 allele on the small
Answer:
(i) Small island
(ii) Large island
(iii) Option-3
Explanation:
In the given question, the three population of the Anoles Lizards migrated to three islands of different size.
(i) Genetic drift is a random or by the chance process which changes the frequency of the alleles in the population. The change in the frequency of the allele can be easily observed in the small population therefore the small island with the smallest size of the population will have the strongest genetic drift.
(ii) Heterozygosity of alleles that is with a dominant and a recessive allele is the result of the exchange of alleles in the population. The size of the population is finite on the island therefore the heterozygosity is not introduced in the small population but in a large population, it can be introduced as the mating is random.
(iii) The genetic drift is strongest on the small island therefore L2 allele can be easily influenced by this effect. The selection coefficient is very small that is 0.002 therefore no mutation is occurring on the island.

In humans, XO individuals are females with Turner syndrome and XXY individuals are males with Klinefelter syndrome. Red green color blindness is caused by an X-linked recessive allele. Suppose a colorblind man and a normal woman with no family history of color blindness married and had a daughter who was colorblind and had Turner syndrome.
1. Which event could have given rise to this offspring?
A) Nondisjunction at meiosis II in the mother.
B) Nondisjunction at meiosis I in the father.
C) Nondisjunction at meiosis l in the mother.
D) Nondisjunction at meiosis II in the father.
E) Nondisjunction at either meiosis I or meiosis II in the mother.
Answer:
The correct answer is option E) "Nondisjunction at either meiosis I or meiosis II in the mother".
Explanation:
Nondisjunction is a phenomena at which chromosomes are not properly separated during anaphase. This can either happen at meiosis I or meiosis II during oogenesis. Nondisjunction would explain the XO chromosomic condition of the daughter with Turner syndrome as well as the X-linked recessive allele of the red green color blindness. Nondisjunction happened in the mother because the father could not inherited an X-linked condition.

Answer:
Explanation:
The skull is located in the head. The bone of the skull of a new born is not fused at birth this is to enable passage during birth from the female opening while the skull bone of an adult at joined or linked to the other by sutures, this allows for growth of the skull as the child develops.
At birth the bone is 44 and are separated by a structure called fontanels this indicates the softness of the head. This fontanels allows growth of the skull as the child's develops.
What is a possible consequence of increased ocean temperatures due to global warming? Mark all that apply.
Coral reef bleaching
Increased rates of mercury poisoning
Increased storm activity
Sea levels rising along coast lines
Answer:
Coral reef bleaching
Explanation:
The correct answer would be coral bleaching.
Coral bleaching is generally define as the change in color that results from the expulsion of green symbiotic algae from the tissues of the coral.
The expulsion of symbiotic algae from the tissue of coral is usually caused by a change in stressor factors of ocean water such as light, temperature, nutrient.
When the temperature of ocean water increases as a result of global warming, the vibrant color of corals may be lost because the change in stress condition usually leads to the degradation of the algal pigments or outright expulsion of the symbiotic algae from the tissue of the corals. When this happens, it leaves the coral tissues completely white and they are said to have been bleached.
