Which of the following symbiotic relationships is considered parasitic?
A. Tapeworm in an intestinal tract
B. Bees transporting pollen from flowers
C. Pilot fish swimming under sharks
D. Birds eating the insects from the back of a hippopotamus

Answers

Answer:

A. Tapeworm in an intestinal tract.

Explanation:

This symbiotic relationship is parasitic because the tapeworm causes harm to the host. Tapeworms feed off the nutrients the host consumes, thus making the host sick.

Not parasitic:

Bees transport pollen from flowers back to the nest to feed the young bees, but pollinate female flowers as well which keeps the flower population alive.

Pilot fish swim under sharks to keep other prey from eating them, and the shark do not eat eat the pilot fish.

Birds eating the insect of the back of a hippopotamus keep the hippo clean and parasite-free as well as feeding the birds.

The presence of tapeworm in intestinal tract is considered parasitic. Thus, the correct option is A.

Symbiotic relationships refers to the association between two two organisms belonging to different species. There are three types of symbiotic relationships which are mutualism, commensalism and parasitism.

In mutualism, both of the organisms involved are benefited from the relation.

In commensalism, one of the organisms involved is benefited and the other is neither benefited nor harmed from the association.

In parasitism, one of the organisms involved is benefitted and the other one is harmed from the association.

As in the relationship between tapeworm and human, tapeworm is benefited but the human involved is harmed. Thus, it is a parasitic relation.

Thus, the correct option is A.

Which causes waves in the ocean to occur?

Earth’s rotation
Earth’s gravitational pull
energy being transferred from wind
energy from the Sun heating water

Answers

Answer: Energy being transferred from wind

Explanation: I just answered this question

Waves in the ocean are occurs due to the transfer of energy from the wind. Therefore, option C is correct.

What causes waves in the ocean?

Numerous events, including earthquakes, volcanic eruptions, and landslides, can result in waves, although surface waves brought on by winds are the most frequent ones (CoastalCare). A wave forms when the wind blows across the water's surface, generating friction between the air and the water.

There are numerous types of waves, including tidal waves, wind waves, ocean swells, and tsunamis. Three factors: the wind's speed, the length of time it takes to cross the ocean, and the distance it travels, all affect how large the waves become.

The most common cause of the formation of waves in the ocean is the transfer of energy from the wind. Therefore, option C is correct.

Which three descriptions or examples can be classified as endocrine control?

aldosterone causes the kidneys to reabsorb water
regulates the body using hormones
a signal initiates the contraction of a muscle

Answers

Answer:

vasopressin acts on renal cells to maintain the body's water and salt balance

aldosterone causes the kidneys to reabsorb water

regulates the body using hormones

Explanation:

if i pick all of them i see which ones are right and which ones are wrong, your welcome :)

The three descriptions that can be classified as endocrine control are :

Vasopressin acts on renal cells to maintain the body's water and salt balance ( A ) Aldosterone causes the kidneys to reabsorb water ( D ) Regulates the body using hormones ( E )

Endocrine control is the process of controlling, mood, growth and development by the endocrine hormones. The amount of endocrine hormones produced is dependent on the amount of hormones present already in the system of an individual and it is regulated by the endocrine system.  

Some of the functions performed by the Endocrine system includes the regulation of body using hormones, aldosterone which is an endocrine hormone causing kidneys to reabsorb water.

Hence we can conclude that the three descriptions of endocrine control is as listed above.
