When a nerve impulse reaches the end of an axon of a neuromuscular junction, calcium flows ______ the synaptic knob.

Answers

Answer: flows INTO the synaptic knob.

When a nerve impulse reaches the end of an axon of a neuromuscular junction, calcium flows into the synaptic knob.

In a neuromuscular junction, there are three parts. They are the presynaptic terminal or synaptic knob, the synaptic cleft and the postsynaptic terminal. The calcium ions will work in the synaptic knob when the nerve impulse arrives.

Once that the nerve impulse reaches the end of the axon, it will affect the presynaptic terminal. In there, it causes the opening of voltage-gated calcium channels. As a result:

Calcium flows into the presynaptic terminal.The calcium makes the vesicles (with neurotransmitters) descend and fuse with the terminal membrane to release the neurotransmitters to the synaptic cleft.

In conclusion, the nerve impulse causes the opening of voltage-gated calcium channels, and calcium flows into the synaptic knob.

Receptors that are especially important for helping a person maintain balance are located in the (A) gyrus cinguli (B) inner ear (C) tendons (D) ossicles (E) ligaments

Answers

The receptors that aid in allowing a person to maintain balance are located within the inner ear.

The human ability to walk upright without falling, and a wide variety of other tasks that we perform as all thanks to our ability to maintain balance. This ability is given to us by structures located deep within the inner ear.

The inner ear is located deep within the lateral side of the head. This ear contains 3 semicircular canals or ducts, which are tiny structures filled with liquid. Each of these canals has an expansion at its end known as the ampulla, which holds within it the very small cellular balance receptors called crista.

16. Which organelle may have allowed early eukaryotes to make food and produce oxygen? (a) the Golgi apparatus (b) the central vacuole (c) the plastids

Answers

Answer:

the plastids

Explanation:

Answer:  

The plastids are the organelles that compose the cells of plants and algae. These contain chloroplasts, which allow them to capture energy from sunlight. If they are ever removed, these cells will eventually lose their ability to photosynthesize food without help from another organism - they have lost an essential organelle. Without the presence of this organelle, eukaryotes may not have been able to use sunlight as a mechanism for producing oxygen or making nutrients such as glucose available for consumption.

The organelle that may have allowed early eukaryotes to make food and produce oxygen is the plastid. The correct option is c.

What is plastid?

The organelles that make up the cells of plants and algae are called plastids. These have chloroplasts, which enable them to absorb solar energy. These frequently include several kinds of pigments that can alter the color of the cell as well as pigments that are employed in photosynthesis.

These cells will eventually lose their capacity to photosynthesize food without the assistance of another creature if they are ever taken out since they have lost an important organelle.

Eukaryotes might not have been able to exploit sunlight to produce oxygen or make nutrients like glucose available for consumption without the presence of this organelle.

Therefore, the correct option is (c) the plastids.

What is responsible for photosynthesis to occur?

The mesophyll cell is responsible for photosynthesis occurs. The majority of the chloroplasts and the primary site of photosynthesis are located in the palisade layer. The area of storage and gas exchange is the airy, spongy layer. The stomata control the water and carbon dioxide equilibrium.

For gaseous exchange and photosynthesis, leaves are suited. Since they have a wide surface area and stomata, which enable carbon dioxide to enter the leaf and oxygen to exit, they are well-equipped for photosynthesis.

Chloroplasts, which is known as the house the chlorophyll in plants, are where photosynthesis occurs. The thylakoid membrane, a third inner membrane that creates lengthy folds inside the chloroplast and is bordered by a double membrane, is present inside chloroplasts.

Therefore, The upper epidermis of the leaf is transparent, allowing light to enter and they have a large surface area to volume ratio, allowing more light to enter.

What evidence of climate change on continents supports the theory of continental drift?

signs that glaciers existed in South Africa
similar coal fields on different continents
change in atmospheric temperature over time
same animal fossils found on different continents

Answers

Answer:

A

Explanation:

Edge2022

The evidence of climate change on continents that supports the theory of continental drift is similar coal fields on different continents. Hence option B is correct.

What is continental drift theory?

The theory of continental drift suggests that the Earth's continents were once joined together in a single landmass called Pangaea, which began to break apart around 200 million years ago.

This idea was first proposed by German scientist Alfred Wegener in the early 20th century, who noticed the striking similarities between the coastlines of Africa and South America.

Coal is formed from the remains of plants that lived millions of years ago, and its distribution can provide clues about how continents were once connected.

Coal fields found on different continents that match in age and composition indicate that the continents were once joined together in a larger landmass.

This supports the theory of continental drift, which states that the continents were once part of a single supercontinent that later broke apart and drifted into their present positions.

This evidence suggests that coal-forming swamps once existed in locations that are now separated by oceans and that these locations were once connected.

Hence option B similar coal fields on different continents is correct.
