Answer:
A
Explanation:
Hello, so we can do this question two ways. 1, we can know what kind of relationship the two types have or 2, we can analyze each relationship and see if it would increase or decrease.
Starting with option 2, we can look at A. A says the population would stay stable because of a commensal relationship. In a commensal relationship, one party benefits and the other neither gains or loses anything. Thus, A could be true because the population would stay stable in this case.
Looking at B, we see it says the population would increase because it has a mutualistic relationship. However, in a mutualistic relationship both species benefit. If the wrasse population died more, that would NOT benefit the other species in a mutualistic relationship, thus B can be eliminated.
Answer C says it would decrease because of its predator and prey relationship. Depending on which one was the predator and which was the prey, one species could benefit from the death of the other while the other didn't. For example, if the wrasses were the prey, the predators would also decrease because they could not eat as well, but if the wrasses were the predators they other population would increase because they would be eaten less. Thus we cannot rule out answer C.
D for an answer is like C, depending on the roles of which was which D could or could not be the answer.
Although method 2 helps eliminate B it still does not tell us the answer, so we look to our knowledge of wrasses and titan tigerfish. Wrasses and titan tigerfish have a commensal relationship. Therefore, one can benefit and the other is neither harmed nor benefited. This relationship is also called symbiotic. Thus, the wrasse population could decrease and since the titan tigerfish do not experience benefits or harm from that species their population will remain the same.
Hope this helps!

What is Haiku?Haiku is a seventeen-syllable Japanese poetry with three lines of five, seven, and five syllables that generally evoke pictures of the natural world.
These are the rules for creating haiku:
There are a total of 17 syllables.Haiku is only three lines long.The first line of a Haiku typically contains 5 syllables, the second line has 7 syllables, and the third line has 5 syllables.Avoid titles and rhyme (both of which are almost never used in haiku), as well as metaphor, simile, and most other rhetorical elements (they are often too abstract or detour around the directness exhibited in most good haiku).
Haikus are historically derived from the Japanese Hokku. Hokkus are group poetry that adhere to the 5/7/5 formula. They are intended to comment on the writers' season or surroundings and to generate some form of contrasting visual split by a kireji or "cutting word."

(80-100 words) What is sickle cell disease? Describe its effects at a protein, cellular and organismal level.
Answers
Sickle cell disease (SCD) is a genetic disorder caused by a mutation in the gene that codes for hemoglobin, a protein responsible for carrying oxygen in red blood cells.
The mutation results in the production of an abnormal form of hemoglobin known as hemoglobin S (HbS). Sickle cell disease is inherited in an autosomal recessive manner, meaning that an individual must inherit two copies of the mutated gene (one from each parent) to develop the disease.
Effects at a Protein Level:
Hemoglobin normally has a rounded shape, allowing red blood cells to flow smoothly through blood vessels. However, in sickle cell disease, the abnormal hemoglobin S causes red blood cells to become stiff and take on a crescent or sickle shape under certain conditions, particularly when oxygen levels are low.
Effects at a Cellular Level:
The sickle-shaped red blood cells are prone to clump together, leading to the formation of blood clots. These clots can block blood vessels, causing a reduction in blood flow to various organs and tissues.

Which could cause a
change to the carrying
capacity of a species in an
ecosystem?
A. seasons changing
B. continuous rotation of resources
C. more predators
D. consistent rain falls
Answers
The carrying capacity of a species in an ecosystem is the continuous rotation of resources. Option B.
As abiotic or biotic factors change so does the carrying capacity. Natural disasters can destroy ecosystem resources. When resources are destroyed, ecosystems can no longer support large populations. This reduces the payload. Increased food production through improved agricultural practices control of many diseases with modern medicine, and the use of energy to render historically uninhabitable areas.
Earth's habitable is an example of something that can expand its carrying capacity. Altering ecosystems can increase the carrying capacity of some species, as other species are overwhelmed and populated while others are dramatically reduced due to hunting. Carrying capacity is the maximum number of individuals in a population that the environment can support.

Additionally, neurotransmitters are in charge of igniting, inhibiting, and modifying neurons that further influence human behavior. The study of physiology focuses on the origins of significant bodily functions, including hunger, behavioral potentials, innate drives, and many other situations that influence our behavior.

22. Drosophila melanogaster is a species of fruit fly commonly used to investigate patterns of genetic inheritance. Flies with a curled wing mutation have deformed wings and cannot fly. Wild-type flies have normal wings.
Fruit fly eye colour is also under genetic control. Wild-type flies have red eyes while mutant flies have white eyes.
The image below depicts two flies that carry at least one of the mutant phenotypes described above.
a)
i. Define the term wild type. (1 mark)
ii. A pure breeding fly with normal wings and white eyes is crossed with a pure breeding fly with curled wings and red eyes. All of the F1 offspring produced have curled wings and red eyes. Based on this information, use appropriate allelic notation to identify the dominant and recessive alleles for each trait. (2 marks)
b)
Several crosses between an F1 individual from part a) ii. above and a pure breeding fly with normal wings and white eyes produce the following phenotypic results.
Curled wings red eyes = 410 flies; Normal wings white eyes = 470 flies
Curled wings white eyes = 81 flies; Wild type for both traits = 79 flies
Use this information to determine if these genes are linked or unlinked. Justify your answer. (2 marks)

ai. A wild-type species can be defined as a species whose genotype shows the normal genotype and there has been no mutation in the genetic sequence of the species.
aii. The allelic notation is as follows:
W = curled wings (dominant) w = normal wings (recessive)R = red eyes (dominant)r = white eyes (recessive)b. Based on the obtained phenotypic ratio of 6 : 1 :1 : 6 instead of the expected phenotypic ratio of 1 : 1 :1 : 1, curled wings red eyes as well as Normal wings white eyes are linked genes.
What are genotypes?Genotypes refer to the sum of the genetic makeup of a species. The genotype of a species refers to the sum total of the allele of a gene that an organism has.
The genotype of a species determines the phenotype of that species.
The phenotype refers to the physical expression of the genotype of a species.
Wid-type species are species that have not undergone a mutation.
Considering the given data:
W = curled wings is dominant
w = normal wings is recessive
R = red eyes is dominant
r = white eyes is recessive
b. The F1 generation be WwRr
The cross: WwRr x wwrr:
Expected genotypes (phenotypic ratio): WwRr x4 (curled red); Wwrr x4(curled white); wwRr x4(normal red); wwrr x4 (normal white)
Phenotypic ratio = 1 : 1: 1 : 1
