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.

A. They are equally able to exchange gases with the environment while stationary.
B. They are highly maneuverable due to their flexibility.
C. The have paired fins.
D. A swim bladder helps control buoyancy
E. They are equally able to exchange gases with the environment while stationary.
F. They are highly maneuverable due to their flexibility.
G. They have paired fins.
Answer:
C and G
Explanation:
The statement that accurately describes a similarity between sharks and ray-finned fishes is the possession of paired fins.
Sharks and ray-finned fishes are species of fish that belongs to a group called Chondrichthyes, which are characterized by their jaws.Sharks and ray-finned fishes are cartilaginous fishes i.e. contain cartilage rather than bones. Sharks and ray-finned fishes do not possess a swim bladder for buoyancy. They also both possess paired fins (pectoral and pelvic) joined together by a bone. Therefore, the statement that accurately describes a similarity between sharks and ray-finned fishes is the possession of paired fins.Learn more at: https://brainly.com/question/20421579?referrer=searchResults

If Ryan were to become less active, what would happen to the number of extra calories he could consume. Explain plz!!!
Answer: The food consumed by the person may contain extra calories more then what is actually required by the body for daily physical work.
Explanation:
The extra calories can become harmful for the person if the routine daily activity becomes slow and less frequent. The extra calories will become the source of deposition of fats in the body. As the calories will not be used or burned out thus may be responsible for development of cases of obesity or overweight. The person may experience problems like diabetes, hypertension, and heart stroke.
Ryan will become obese if consume extra calories and become less active.

Explanation:
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:
Coal is formed by the dead plants, its original source comes from the sun, coal is used as a resource for fire. It could possibly form today because of how many plants grow each day.
Coal is a fossil fuel which is formed by the remains of the pre-historic ties organisms such as plants and animals. This process takes place over the time of millions of years.
What is the process of Coal formation?Coal is a fossil fuel or the fuel which comes from the remains of the pre-historic plants or animal species. The formation of coal is the process which occurs over the time of millions of years through a process known as carbonation process. In this process, dead vegetation is converted into carbon-rich coal under the condition of very high temperature and pressure.
