What is the first aid for cramps?
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 .

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?
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.

Answer:
The law of conservation of mass
Explanation:
The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.

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

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
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.
describe the role of soil organisms in soil structure and development
Answer:
One of the most important roles of soil organisms is breaking up the complex substances in decaying plants and animals so that they can be used again by living plants. This involves soil organisms as catalysts in a number of natural cycles, among the most prominent being the carbon, nitrogen, and sulfur cycles.

How do ultrasound waves clean jewellery
Answer:
They use ultrasound waves and chemicals combined to create bubbles that "cling" to the foreign particles such as dirt, oil, and unknown substances.
Explanation:
Ultrasonic cleaners are useful for jewelry cleaning and removing tarnish. They use ultrasound waves and chemicals combined to create bubbles that "cling" to the foreign particles such as dirt, oil, and unknown substances. The high frequency waves are sent out and pull the contaminants off the object.
Answer:
Ultrasound waves and chemicals are combined to create bubbles that "cling" to foreign particles such as dirt, oil or other unknown substances. The waves are sent out to extract these particles.

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

Explain how to focus a microscope using the high power lens. Include any safety issues you need to be aware Answer
Answer:
Include any safety issues you need to be aware of. Answer: To focus a microscope using the high-power lens you have to use the focus adjustment knob but be careful because if you crank down too hard, you can damage the microscope and the slide.
Explanation:
Look through the eyepiece (1) and move the focus knob until the image comes into focus. Adjust the condenser (7) and light intensity for the greatest amount of light. Move the microscope slide around until the sample is in the centre of the field of view (what you see).You must be very careful when using the high power lenses so you do not jam them into the slide. Ocular Lens - The ocular lens, or eyepiece, magnifies the image.

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.
