Becky is experiencing chronic pain from a medical condition that cannot be treated. In order to minimize the long-term emotional response to her pain, she would choose a modification of her a. Parietal cortex. b. Prefrontal cortex. c. Primary somatosensory cortex. d. Dorsal lateral thalamus. e. Posterior cingulate cortex

Answers

Answer:

b. Prefrontal cortex.

Explanation:

The prefrontal cortex is the cerebral cortex that covers the frontal lobe in the brain. The prefrontal cortex plays important roles in pain processing, as well as in pain modulation. In addition, this brain area is connected to other brain regions including the hippocampus, thalamus, amygdala, and further areas of the cerebral neocortex. It has been shown that changes in gene expression patterns, glial cells, neurotransmitters and inflammatory processes are triggered in the prefrontal cortex during both acute and chronic pain, and these alterations are able to modify its functioning, structure, and connectivity.

Answer:

These are just the answer key. You will have to fill in the lower half of the questions yourself. I did not consider 32% and 1.6% approximately the same but the answer key did.

Hope this helps:)

Explanation:

The box’s measurements are: length = 50 cm, width = 25 cm, and height = 25 cm. The measurements of the block are: length = 10 cm, width = 10 cm, and height is 5 cm.

Out of 100 marble drops or shots, the marble hit the block 32 times.

volume of the box = 50 × 25 × 25 = 31250 cm 3

volume of the block = 10 × 10 × 5 = 500 cm 3

Ratio = 500/31250 = 0.016 × 100 = 1.6%

The volume of the block is 1.6% of the volume of the box

Ratio = 32 hits/100 shots = 0.32 × 100 = 32%

The block was hit 32% of the time.

Percentages will be similar and both be small percentages

Answers will vary.

Explain 3 ways of checking soil depletion​

Answers

You can check soil depletion by:

1. Contour ploughing

Ploughing along contours on a slope prevents soil from being washed away by rains and or by surface run-offs. Contours act like bunds. Terraces are leveled into step-like small fields with even slopes. Doing this is common in Asian countries.

2. Terrace Farming

On hilly slopes, terraces act as bunds and prevent the soil from being washed away by running water. This is practiced in Asia and the USA.

3. Strip Cropping

In this system, crops are grown by alternate strips of land in order to check the effect of the winds.

3. How do seasonal changes in temperature, water availability and sunlight affect ecosystems?
4. Propose 5 ways that humans can help minimise the negative effects both natural events and human impact can have on ecosystems.

Answers

Answer:

1. The large number of the pollution going into the air becaue of overfarming, and the high demand for unrenewable resources.

2. The positive impacts that floods can have is that they can water plants for places in drought like places such as California. For areas that are vastly dry, rain could be essential to humans, plants and animals in need of it.

3. These changes affect the ecosystem puts the ecosystems in a rather different situation than the ecosystem and those supported by it to adapt to the newcomings occuring of different seasonal changes and much more.

4.

-There can be alternatives to not destroying unrenawable resources.

-Use electrical cars that don't pollute the air.

-Be resourceful with their water and don't use more than needed.

-don't litter.

-recycle.

Why only certain cell undergo mitosis
and why other cells undergo meiosis

Answers

Explanation:

Mitosis allows for cells to produce identical copies of themselves, which means the genetic material is duplicated from parent to daughter cells. Mitosis produces two daughter cells from one parent cell. Single-celled eukaryotes, such as amoeba and yeast, use mitosis to reproduce asexuallyand increase their population. Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. ... Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome.

What is the first aid for cramps? ​

Answers

Answer:

Take a hot shower

Massage the cramped area

Yup thats all i know

We all know that any cramp in our muscles is formed due to the secretion of lactic acid . This lactic acid is formed due to our muscles doing anaerobic respiration instead of aerobic respiration . Our muscles require oxygen to break down glucose itn energy and carbon dioxide . But our body muscles wont get this much needed oxygen due to which they will start to do anaerobic respiration where they produce energy without the usage of oxygen . When such a respiration happens lactic acid is secreted in our stomach , which makes our muscles start to form cramps . So we can say that tightness or soreness of muscles due to our muscles lacking oxygen is called as muscle cramps . So , a hot bath will be a very good remedy for cramps as it will let the oxygen pass through the body , thereby completely help the lactic acid turn into energy . When lactic acid breaks down completely to form energy the muscle cramps go away . Another first aid for cramps would be massaging the area with cramps . This will also increase the oxygen flow thereby making the lactic acid change into oxygen due to which the pain will go away . Another remedy for muscle cramps would be hot nor cold pads as they help ease the pain .

state 4 ways by which through which a soil is depleted ​

Answers

Answer:

Explanation:

Leaching – Plant nutrients are lost beyond the reach of plant roots. Usually caused by excessive rainfall washing nutrients deep down into sub-soil beyond new roots reach.

Soil erosion – Top soil is lost by the agent of erosion e.g. wind, water.

Monocropping – This utilizes only specific nutrients from a particular zone making it exhausted. -It also causes accumulation of certain pests and diseases.

Continuous cropping –This continuously exhaust the fertility of land unless the the land if fallowed.

Change of soil PH -Use of either acidic or basic fertilizers affect soil pH and Consequently the presence of micro-organisms hence soil fertility affected.

Burning of vegetations –Destroys organic matter and soil structure. Nutrients are lost and soil exposed to erosion.

Accumulation of salts – Common in waterlogged areas and semi-arid areas in which poor drainage causes evaporation during the dry periods, making the soil saline.

Explanation:

Aquatic organisms are able to survive when the temperature decreases. These organisms survive even when the surfaces of lakes and ponds are covered with ice. Which property of water best explains how aquatic organisms can survive during freezing temperatures?

Answers

Answer:

Anomalous expansion

Explanation:

Anomalous expansion of water is the abnormal way water expands when exposed to low temperature.

At 4 degree Celsius , the density at the top layer is usually at the Maximum which makes the water sinks down and then the water in the lower layer rises up.

When the temperature drops below 4 degree Celsius, the water molecules at the top then freezes leaving the denser molecules at the bottom which doesn’t freeze as a result of their high density.

This way, organisms can survive in the water due to the lower layer not freezing.
