What portion of the nervous system both delivers commands to the muscles directing voluntary movement and communicates information back to the central nervous system?.

Answers

Somatic nerves deliver commands to the muscles directing voluntary movement and communicating information back to the central nervous system.

The somatic nervous system is the part of the peripheral nervous system that is associated with the voluntary movements of the body.

It involves the nerves that go into muscles and skin and control the conscious movements of our body.

The somatic nerves enable to control and movement of the muscles throughout the body.

It feeds information related to our senses such as sound, taste, touch, and smell, back to the central nervous system.  

Our sense of touch also uses somatic nerves to send information back to the central nervous system.

Only sight sense is the exception because the optic nerve cells are directly connected with the brain.

. What determines whether the relationship between a fungus and a plant is commensalism, mutualism, or parasitism?

A.) Where the fungus is located in the plant.
B.) How long the fungus survives in the plant.
C.) Whether the fungus reproduces in the plant with spores, seeds, or runners.
D.) Whether the effect of the fungus on the plant is neutral, positive or negative.

Answers

Whether the effect of the fungus on the plant is neutral, positive or negative determines whether the relationship between a fungus and a plant is commensalism, mutualism, or parasitism.

Plant and fungi characteristics

Symbiotic interactions called mycorrhizae develop between fungi and plants. In exchange for improved water and nutrient uptake, the fungi invade the roots of a host plant and receive carbohydrates produced during photosynthesis from the plant.

Chlorophyll exists in plants. Chlorophyll does not exist in fungi. Most plants have stems, roots, and leaves. Hyphae are part of the fungus's body (they interconnect to form mycelium). Their cells each have a nucleus and membrane-bound organelles since they are both eukaryotic, which means they are both members of the Eukarya domain. Both of them are stationary, include many cells, have cell walls, and are frequently multicellular.

Cathy's favorite salad dressing is a liquid with particles of salt, pepper, and garlic. When comparing a spoonful of salad dressing to a cell, what would the liquid be equivalent to? What would the particles be equivalent to?

Answers

Answer:

Liquid equivalent to "cytoplasm" and the particles equivalent to "organelles".

Explanation:

While comparing a liquid salad dressing to a cell, the liquid will be equivalent to "cytoplasm" because cytoplasm is a thick solution present in each cell that made up of water, salts, and proteins.

The particles would be equivalent to "organelles" because as particles float in liquid salad adding flavours to the salad likewise organelles are present in a cell floating in the cytoplasm that performs a specific function.

Hence, the correct answer is " liquid will be equivalent to "cytoplasm" and the particles will be equal to "organelles".

Mr. m ripped his ear in a wrestling competition. the first-aid attendant attempted to diminish the bleeding by pressing the ________ artery against the side of the skull.

Answers

The first-aid attendant attempted to diminish the bleeding by pressing the carotid artery against the side of the skull.

The carotid artery is a major blood vessel located in the neck that supplies oxygenated blood to the brain. By applying pressure to the carotid artery, the attendant is aiming to reduce the blood flow to the injured ear, thus minimizing the bleeding.

To locate the carotid artery, place two fingers on the side of the neck, between the windpipe and the muscle running along the side of the neck. The carotid artery can be felt pulsating. Gently pressing on this artery can help slow down the blood flow, allowing for better clotting and diminishing the bleeding.

It's important to note that the first-aid attendant should have prior knowledge and training in applying pressure to the carotid artery. If the bleeding is severe or the injury is extensive, immediate medical attention should be sought.

In summary, the first-aid attendant attempted to diminish the bleeding by pressing the carotid artery against the side of the skull. This can help reduce blood flow to the injured ear and promote clotting.

What would happen if the mitochondria were missing from a cell?

Answers

Answer:

We'd be in big trouble...

Explanation:

The mitochondria is the powerhouse of the cell, without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration.

The absence of mitochondria would have a profound effect on cellular function, including the cell's ability to produce energy, regulate ROS levels, and control important signaling and metabolic pathways. Such a cell would likely be unable to survive for very long.

What is the effect of mitochondrial removal?

Without mitochondria, the cell would not be able to generate ATP through aerobic respiration, which takes place in the mitochondria. Instead, the cell would have to rely on other, less efficient metabolic pathways to produce energy. Mitochondria are also important for regulating the levels of reactive oxygen species (ROS) in the cell. Without mitochondria, the levels of ROS would likely increase, leading to oxidative damage to the cell's proteins, lipids, and DNA. Mitochondria play important roles in cell signaling pathways, including those involved in apoptosis (programmed cell death) and calcium signaling. Without mitochondria, these pathways would likely be altered, which could have profound effects on cellular function and survival.

Hence, such a cell would likely be unable to survive for very long.

which of the three available growth options for porcini would you recommend and why

Answers

Some of the growth options that are commonly used for porcini include:1.Outdoor cultivation .2.Indoor cultivation 3.Hybrid cultivation.

1.Outdoor cultivation: Porcini mushrooms grow well in a temperate climate with adequate moisture, and can be grown in natural habitats or in a forest-like setting. This option is less expensive but may result in low yields.

2.Indoor cultivation: Porcini mushrooms can also be grown indoors in a controlled environment, which allows for a more consistent yield and better control of factors such as temperature, humidity, and light. However, this option is more expensive and requires specialized equipment and a higher degree of technical expertise.

3.Hybrid cultivation: This option involves a combination of indoor and outdoor cultivation, with the initial stages of growth taking place indoors and then transferring the mushrooms to an outdoor environment to complete their growth cycle. This option provides a balance between cost and yield and can be a suitable option for growers who want to reduce the risk of crop failure.

(Choice C) C The transport of sodium against its concentration gradient in a brain cell. (Choice D) D The passive transport of a charged potassium ion (K^+ + start superscript, plus, end superscript) through a cell membrane.

Answers

The process of cell transport that would be relatively unaffected if a cell no longer had access to glucose is the transport of calcium into a muscle cell via facilitated diffusion. Thus, the correct option is A.

What is Cellular respiration?

Cellular respiration may be defined as the chemical process through which the breaking down of food occurs with the liberation of energy. This process takes place in the excess of oxygen and constructs energy from carbohydrates (sugars).

The excess glucose delivers the required energy for the cell to perform its metabolic activities. But when the amount of glucose is not significantly present in the cell, the process of transport of calcium into a muscle cell via facilitated diffusion remains unaffected.

This is because the transport of calcium occurs due to paracellular passive transport without the utilization of energy. While the rest of the process requires energy for the transport.

And due to a lack of glucose, cells do not have the ability to derive energy in form of ATP.

Therefore, the process of cell transport that would be relatively unaffected if a cell no longer had access to glucose is the transport of calcium into a muscle cell via facilitated diffusion. Thus, the correct option is A.

r-strategist are species that have large offsprings, but spend no time in parental care.  Sea turtles can be considered exaples of r-strategist species.

What are r and k strategists?

Species have different strategies to survive in different environments, reproduce, disperse, and compete. These strategies are r strategies and k strategies.

r strategist species have a high growth rate per capita, and low competition capabilities. This is why they can colonize new environments. But they can not compete with new-established species. r species are often displaced by k species.

These species are mostly small-sized organisms with short life cycles. They reach sexual maturity early and have numerous descendants spending no time or energy in parental care.

k strategist species have a low growth rate per capita, but they are big competitors with the capacity of displacing other species and monopolizing the available resources.

These are big-sized species that live for a long time, reaching sexual maturity in the advanced stages of their lives. They do not have numerous progenies, but they spend time parenting.  

r and k strategies are closely related to reproductive strategies, habitat selection, and dispersion ability.

Considering this difference, we can assume sea turtles are r strategist.

They lay several eggs and leave them on the beach. They spend no energy in parenting. Even though they are buried, eggs are still in danger of being attacked by predators.When little turtles emerge, they have to manage to go to to the sea by themselves, being exposed to other predators.

The strategy is to spend more energy in laying several eggs to increase survival probabilities, and less energy in parenting.
