The Zooxantelae and the hard coral are in a mutualistic relationship. This means that both the hard coral and the algae benefit from this relationship. The coral gets extra nutrients produced by the photosynthesizing algae, and the algae gets protection and a stable environment by living inside the coral tissue.
The case of the remora and the manta ray is a perfect example of commensalism. In this type of relationship, one of the participants has benefits, and the other participant has no benefits, nor costs. The remora gets ''leftovers'' from the manta ray, and possible protection from larger predators and the manta ray does not benefit from this relationship.
The tiger shark prays on the green sea turtle, so this is a clear example of predation.
The trevallies and the dolphins are both apex predators, therefore they are competing against each other for pray.
b. circulatory, excretory, nervous, endocrine
c. respiratory, excretory, nervous, endocrine
d. circulatory, respiratory, nervous, endocrine
Answer:
option D : circulatory, respiratory, nervous, endocrine
Explanation:
The circulatory system of the body maintains the flow of oxygen, nutrients and blood in the body. The respiratory system allows the uptake of oxygen and exhalation of carbon dioxide. Thus maintaining oxygen requirement of the runner. The nervous system regulates the process of breathing in the body. The endocrine system provides signals that works together with respiratory system.
The integumentary system comprises nail, skin, exocrine glands and hairs. The excretory system involves removal of waste from the body. Thus, option D is correct.
Answer:
The answer is B: Haplorhines have better color vision.
Explanation:
Haplorhines are known as dry-nosed while Strepsirhines are known as wet-nosed. Haplorhines and Strepsirhines are two different kind of primates but they have different characteristics such as variation of the brain size, because Haplorhines have bigger brain than Strepsirhines, Haplorhines do not have the enzyme in charge of producing Vitamin C while Strepsirhines have it. Haplorhines have a more developed vision than Strepsirhines. In this sense, Haplorhines possess a layer called tapetum lacidum which allows them to see at night when the light is low, while Haplorhines do not possess tapetum lacidum but, they have something called fovea, which help the to see during the day and have a vision color which is not a feature of Strepsirhines.
Haplorhines and Strepsirrhines are two main classifications of the Order Primates. Strepsirrhines are the wet-nosed primates, primarily nocturnal with larger olfactory centers. Haplorhines, dry-nosed primates, are often diurnal, rely more on vision and need vitamin C from their diet.
The Order Primates is segregated into two groups: Strepsirrhini (“turned-nosed”) and Haplorhini (“simple-nosed”) primates.
Strepsirrhines, also known as the wet-nosed primates, include prosimians like bush babies and pottos of Africa, the lemurs of Madagascar, and the lorises of Southeast Asia. These primates are primarily nocturnal, have larger olfactory centers in the brain, and tend to be smaller in size with smaller brains compared to anthropoids.
On the other hand, Haplorhines, or dry-nosed primates, include tarsiers and simians (New World monkeys, Old World monkeys, apes, and humans). Typically, Haplorhines are diurnal, rely more on their vision, and lack enzymes to produce vitamin C, thus, needing to get it from their food. Distinctive anatomical traits of strepsirrhines include a grooming claw on their second toe and protruding incisors forming a toothcomb. Haplorhines further diversify into Simiiformes and Tarsiiformes with distinctions being narrow nostrils, non-existent or functional tails, and their habitat.

Answer:
Aldosterone.
Explanation:
Aldosterone is a hormone that regulates the levels of sodium and potassium in our body, which leads to regulate our fluid levels.
In order to increase the fluids in our system, aldosterone causes the absorption of sodium from our kidneys. The kidneys are the place where our body filters the blood absorbing what it needs, such as sodium, and excreting the rest as urine. With the entering of sodium to our bloodstream, water also enters, increasing the volume of blood in our body.
Aldosterone is also responsible for the excretion of potassium into the urine, controlling the levels of this ion, which is extremely important for a high number of reactions.
