Which best describes an example of conduction? a heater warming a room water boiling in a pot on a stove an ice cube melting in a cup of hot chocolate cold water moving toward the bottom of a swimming pool
Answer:
boiling in a pot on a stove
Explanation:
Conduction is one of the methods of heat transfer (the other two being convection and radiation). Conduction is the direct transfer of heat through a solid medium. The heat causes the molecules of the objects, which are in direct contact with one another to vibrate, hence, passing the heat.
Based on the above description of conduction, the example that best fits this is BOILING IN A POT ON A STOVE. This is because the pot is in contact with the stove, which is the source of the heat. Hence, heat is transferred from the stove to the pot.

Does the plant use all wavelengths of light to carry out photosynthesis? Why does this make plants look green?
Answer:
Chlorophyll, the green pigment common to all photosynthetic cells, absorbs all wavelengths of visible light except green, which it reflects. ... All photosynthetic organisms have chlorophyll a which absorbs violet-blue and reddish orange-red wavelengths. Chlorophyll a reflects green and yellow-green wavelengths. Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs.

Give two uses of energy transferred by respiration in eukaryotes
Answer:
Most aerobic respiration takes place inside mitochondria. Some of the energy released in respiration is used to make larger molecules from smaller ones, to enable muscles to contract and to keep temperature steady. Some of the energy released in respiration in plants is used to make amino acids and proteins.
Explanation:google said it and i had this question in my science class and got it right
The uses of energy are - energy for metabolic reaction and growth and development of cells.
Cellular respiration provides energy with the series of complex chemical reaction cycles that is used for:
Working your muscles - for movement and physical activities energy is required.Growth and repair of cells - dividing cells, repairing them and development of the cells also require energy.Building larger molecules from smaller ones for instance proteins from amino acids.Allowing chemical reactions to take place.Absorbing molecules in active transport.Thus, The uses of energy are - energy for metabolic reaction and growth and development of cells.

Identify the type of mutation that occurred and explain in what way it affected the protein
Answer:
The type of mutation that occurs when in the DNA strand there is a change from guanine to cytosine is a nonsense mutation, since the triplet that should encode the amino acid encodes a stop codon and the protein cannot be completely synthesized.
Explanation:
The nonsense mutation consists of a change in one of the bases of the stranded DNA, which is transcribed into an altered mRNA, producing a stop codon, instead of an amino acid.
In the table it is observed that the CCA codon is a stop codon that cuts off the protein synthesis prematurely, leaving it incomplete and probably non-functional.
Sometimes this type of mutation can alter the sequence of amino acids but the protein may be complete enough to partially fulfill its function.

Which term applies to muscle cell
A) prokaryotic
B) eukaryotic
C) unicellular organisms
D) stem cell
Stem cell term applies to muscle cells.
What are the functions of stem cells?Stem cells are the cells that develop into blood, brain, bones, and all of the body's organs. They have the potential to repair, restore, replace, and regenerate cells, and could possibly be used to treat many medical conditions and diseases.
While they can regenerate themselves in an animal or person they are generally very difficult to grow and to expand in the laboratory. Because of this, it is difficult to obtain sufficient numbers of many adult stem cell types for study and clinical use.
Stem cells originate from two main sources: adult body tissues and embryos. Scientists are also working on ways to develop stem cells from other cells, using genetic “reprogramming” techniques.

Why would you be unable to run forever without your muscles giving
out?
Well The body converts glucose to energy which produces lactic acid as a by-product. As that builds up in the muscles, it begins causing cramps and fatigue as a signal to stop. So you have to stop when you reach the lactate threshold. And Over the course of a sustained run at half-marathon pace or faster, the amount of energy (and thus oxygen) needed to maintain that pace gradually inches upward. Over the course of 10-20 minutes, your oxygen consumption can drift upward by as much as 25 per cent, making it progressively harder for you to Hold up.
I Hope this Helps! May I Have brainliest? <3
I would be unable to run forever without my muscles giving out is as a result
of stress , shortage of glucose and build-up of lactic acid.
When activities are performed by muscle tissues , the glucose is usually
converted to energy with the release of lactic acid.
The shortage of glucose and build up of lactic acid brings about fatigue and
wearing out of the tissues thereby making us unable to run forever.

In the life cycle of a Spider, there are no larvae, pupae, or nymphs stage.
Explain the life cycle of a spider.The first stage, egg
When a female has mated, she stores her spermatophores until she is ready to lay her eggs. The number of eggs is between a few and tens of thousands.
The second stage, egg sacs
The progeny develops in the egg sac, which was designed to shield the eggs from the weather and from predators like birds and ants.
The third stage, spiderlings
The young spiders that resemble their parents the most are called spiderlings.

The image below shows a close-up of the crystals formed in a pegmatitic rock. Which characteristic provides the best evidence that is rock solidified deep underground?
low density
light color
very coarse texture
Answer:
Option C (very coarse texture) is the appropriate one.
Explanation:
Everything always cools quickly because once magma reinforces above that of the ocean floor and perhaps the shape it possesses seems to be agricultural context, color temperature, and so on. But as magma settles down underneath the layer, it gets sufficiently opportunity to solidify, culminating in a much more gritty texture as well as color change, respectively. We then assume that perhaps the assumption of whether concrete solidified buried underground correlates to a rather coarse framework.Other decisions aren't linked to the circumstance issued. So the one above is indeed the best one.
