How did the new island in the Pacific Ocean near the Vava'u Islands form? See below
for a picture of the new islands and for the location on earth.
Answer:
They were created from the subduction of the western-moving Pacific plate under the Australia-India plate at the Tonga Trench. The Tongan Islands sit on the Australia-India plate just west of the Tonga Trench. These volcanoes are formed when materials in the descending Pacific plate heat and rise to the surface.
Explanation:
The new island in the Pacific Ocean near the Vava'u Islands forms as divergent plates allow magma to come to the surface at this location. The correct option is a.
What are Vava'u Islands?Vava's island is a group of islands that contain one large island and 40 smaller islands. They are present in the Tonga region.
They were formed as a result of the subduction of the Australia-India plate beneath the western-moving Pacific plate at the Tonga Trench.
West of the Tonga Trench on the Australia-India plate is the Tongan Islands. When elements in the descending Pacific plate heat up and rise to the surface, volcanoes like this are created.

:Katie:I think that plants need to eat but don’t need to breathe.
Hugo:I think that plants need to eat and need to breathe.
Danielle:I think that plants need to breathe but don’t need to eat.
Liam:I don’t think plants need to eat or breathe.
Circle the person you most agree with. Explain why you agree with that person

which receptors respond to stimuli within the body?
Answer:
Sensory receptors respond to stimuli.
Explanation:
They can be classified by their location, the type of stimulus they detect or by their structural complexity.
Sensory receptors are the receptors which respond to stimuli within the
body. The body have five major sensory organs which include the eyes,
nose, tongue, ear and skin.
These organs have receptors which is responsible in the transmission of
signal to the brain for action. The brain acts depending on the signal
received which is usually in the body's best interest.
This makes our sensory organs important and very delicate and as a result
should be adequately protected and taken are of.

Scientists can study the human genome using DNA fingerprinting.
DNA fingerprinting allows scientists to
B. break the hydrogen bonds in a gene to allow DNA to replicate itself.
c. determine the location of an abnormal gene on an individual's
chromosome.
A. prevent a gene from matching complementary bases onto a strand of
RNA.
Answer:
your answer is C.
Explanation:
DNA fingerprinting allows researchers to determine the location of an abnormal gene in a person's chromosomes.
What are the steps in DNA fingerprinting?DNA fingerprinting is a laboratory technique used to determine the likely identity of a person based on the nucleotide sequences of certain regions of a person's DNA that are unique to individuals.
DNA fingerprinting was used early in legal disputes, particularly in solving crimes and establishing paternity. It is also used to detect inherited genetic diseases and can be used to identify genetic matches between tissue donors and recipients.
In DNA fingerprinting, researchers collect DNA samples from various sources, such as hair from crime scenes and blood from victims and suspects. They then narrow down scattered sections of repetitive DNA in these samples.

A type of biome that is very dry, with soil made mostly of sand and rock found in California is known as the desert.
What are biomes?Biomes has been considered as the higher level of organization than ecosystems. Biomes are land areas formed by the influence of climate, rainfall, and latitude. There are various kinds of biomes namely desert biome, prairie biome, savanna biome, tropical forest biome, deciduous forest biome, tundra biome, and mangrove forest biome.
The Mojave Desert is a desert that comprises parts of southern California and small parts of Northern California, southwestern Utah, southern Nevada, and northwestern Arizona, in the United States.
A desert is a biome which receives very little annual precipitation. As a result of this it exhibit very hot and dry climatic conditions. The soil generally losses it's fertility which may either become compact or remain in loose form due to erosion like sand. The plants exhibit fleshy leaves so as to prevent the loss of water through transpiration.

Answer:
nephrons
Explanation:
there are about one million nephrons in one kidney which are responsible for urine formation
The microscopic filtering units found in the kidneys that are responsible for urine formation are called nephrons, so here the correct option is option a.
Throughout the nephron, various processes such as filtration, reabsorption, and secretion occur to produce urine. Filtration occurs at the glomerulus, where water and small solutes are forced out of the blood into the Bowman's capsule. Reabsorption involves the selective reabsorption of water, ions, and nutrients from the filtrate back into the bloodstream. Secretion involves the active transport of waste products, excess ions, and toxins from the bloodstream into the filtrate. So here, the correct option is option a.

In the citric acid cycle, the enzyme succinate dehydrogenase catalyzes a reversible reaction using FAD/FADH2 as an oxidizing/reducing agent. Which of the following statements best explains how the redox component of this reaction contributes to the reaction's ability to be reversible under cellular conditions?
A. FAD has no reduction potential when it is enzyme-bound.
B. FAD can be reduced by the sequential addition of one hydrogen at a time.
C. FAD/FADH2 is covalently bound to succinate dehydrogenase.
D. The change in the biochemical standard reduction potential is small.
The statement which best explains how the redox component of this reaction contributes to the reaction's ability to be reversible under cellular conditions is; Choice D: The change in the biochemical standard reduction potential is small.
Discussion:
A reversible process is one in which the system and environment can be restored to exactly the same initial states that they were in prior to when the process occurred, if we go backward along the path of the process.
However, the necessary condition for a reversible process is therefore the quasi-static requirement.The quasi-static requirement in this case is that the change in the biochemical standard reduction potential is small.Read more:

Answer: T1-T11; two adjacent ribs
Explanation:
The anterior rami of spinal nerves T₁ - T₁₁ are called intercostal nerves because they travel in the intercostal space sandwiched between two adjacent ribs.
What are the rami of spinal nerves?A typical spinal nerve typically branches out into rami as soon as it exits the intervertebral foramen.The smallest of the two main branches is the posterior (dorsal) ramus. It innervates the skin of the back as well as the deep muscles of the back, such as the transversospinalis and erector spinae. The bigger of the two main branches is the anterior (ventral) ramus. The anterior ramus divides into numerous additional branches that innervate the upper limbs, lower limbs, and anterior and lateral regions of the trunk.
