Explanation:

somatic reflex occurs in skeletal muscles whereas, the visceral reflex occurs in soft tissue organs.

The difference between visceral reflex arcs and somatic reflex arcs is that visceral turns require two motor neurons.

For instance, somatic reflexes require a direct link between the skeletal muscle and the ventral horn of the spinal cord. The central neuron of a visceral reflex sends a signal to a ganglion, which then sends another signal to the target effector.

While somatic reflexes are aware, visceral reflexes are unconscious. Compared to somatic reflexes, visceral reflexes entail a somewhat slower reaction time.

Visceral reflex arcs use two motor neurons along with glandular tissue and non-skeletal muscle to carry out a reflexive reaction. Skeletal muscles only have one motor neuron, therefore somatic reflex arcs include them.

Therefore, two motor neurons are involved in visceral arcs, which differ from somatic.

Community ecology!

Explanation:

I’m just did this assignment and got it right <3

A study is conducted to evaluate the effect of competition between foxes and coyotes for a limited food source. The level of ecology being studied is community ecology. The correct option is d.

The ecosystem is the fundamental unit for maintaining life, although it extends beyond species living in a single location. The recycling of resources between organisms and their environments, between organic and inorganic forms, is essential to life.

Community ecology is the study of the structure and function of communities, which are assemblages of interacting populations of species living in a certain area or habitat.

A community in ecology is a group or association of populations of two or more different species that live in the same geographical area and at the same time, also known as a biogenesis.

Therefore, the correct option is d, community ecology.

- The upper epidermis of the leaf is transparent, allowing light to enter

- They have a large surface area to volume ratio, allowing more light to enter

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.

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.

Explanation:

A fault (c) happens at all plate boundaries, so while this is true, it is not the most correct. A subudction zone (b) is where Earth's tectonic plates dive down into the mantle, so this does not answer our question. A rift, in general, is a crack, split, or break in something. A rift in plate tectonics is when plates are moving apart from each other, caused be tension, so a is our answer.

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.

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.

Given what we know about the behavior of gases like helium, we can confirm that the small tank of helium was able to fill so many balloons because the helium expanded to fill its new container, which is the balloon.

Helium is a chemical element known as a noble gas. Like all other elements in a gaseous state, the atoms that comprise helium are spaced apart. This allows the gas to be compressed, a property that manufacturers of the gas take advantage of since they can compress a large amount of gas into a small container.

This is precisely what is happening in the question. The small tank of helium, despite being small in size, contains a large amount of compressed helium gas. Therefore, once it is released from the container, the gas expands to fill its new container, which in this case is the balloons, because of this, a relatively small tank of helium was able to fill many large balloons.

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.

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.
