the particles will have the same kinetic energy
the space between the particles is different with more space between particles in a gas
the particles will have different kinetic energy
the space between the particles is different,with less space between particles in a gas
The particulate nature of matter explains that when a substance gets heated it particles gets energised and they move away from one another in a random manner, hence the correct options are
The space between the particles is different with more space between particles in a gasThe particles will have different kinetic energyWhat happens to particles when they are heated
With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion.
With an increase in temperature, the particles gain kinetic energy and vibrate faster and more strongly

Which of the following initiatives help harvest renewable energy in some TCS offices
The initiative (technology) which help harvest renewable energy in some TCS offices is: Solar water heaters.
TCS is an acronym for Tata Consultancy Services and it is a multinational IT services, consulting and business solutions company that was established on the 1st of April, 1968 in Mumbai, India. Also, TCS has a large network of initiative (technology), innovation and delivery centers across the world.
In 2013, TCS was deeply invested in harnessing renewable energy to generate electrical energy and reducing the emission of carbon, especially by developing solar energy. Thus, solar product solutions such as solar water heaters and lighting systems were installed in some of its offices because they were economically viable and would help meet their energy needs.
In conclusion, solar water heaters was the initiative (technology) that helped harvest renewable energy in some TCS offices.

Biochemists developed a compound that they hypothesize will disrupt the ability of the cells to organize centrioles and microtubules. This compound is applied to a group of onion root tip cells. What will serve as the best evidence that the biochemists' hypothesis about this compound is correct?
The best evidence that the biochemists' hypothesis about this compound is
correct will be lack of growth in the onions.
The centrioles and microtubules are important during the process of cell
division(mitosis) by organisms. They ensure that the cells divide properly
which helps cells to grow.
The compound being hypothesized to disrupting the activities of the
centrioles and microtubules means lack of growth will signify that it is
correct and the most appropriate choice.

noun
a system for the detection of objects under water and for measuring the water's depth by emitting sound pulses and detecting or measuring their return after being reflected.
"a weak sonar signal"
Answer:
0.3106 seconds
Explanation:
Frequency= 20,000-Hz
The speed of echoes sounds can be calculated using the expression below;
Y= ( 2x/t) ...........................eqn(1)
t= overall time taken
x = maximum depth = 230m
Y= speed of echoes sounds
Speed of sound in water= 1,481 m/s which is a constant with little variation.
If we substitute the given values into eqn(1) we have
1481 = (2× 230)/ t
1481 × t= 460
t=460/1481
t=0.3106 seconds
Hence, the minimum time between pulses (in fresh water) is 0.3106 seconds

Distinguish between dimorphic, polymorphic, and continuously variable traits.
Dimorphic, polymorphic, and continuously variable traits are distinguished as follows:
Dimorphism is the condition of those species of animals or plants that exhibit two anatomical aspects or two different forms.When talking about polymorphisms in genetics, reference is made to the different variations that may exist on the DNA of the same gene.Continuously variable traits are those that show a continuous distribution of phenotypes.Therefore, we can conclude that dimorphism is a polymorphism with only two forms, the polymorphism is any stable change of the DNA fixed in the population and in continuously variable traits the phenotypes show a continuous series and cannot be easily grouped.

The β chains of HbA and HbS were treated with trypsin, and the sequence of the N-terminal tryptic peptides are as given below. Do these peptides separate from each other in an electric field if the pH is 7.0? Explain in detail the reasoning behind your answer and include your calculations for the charge of each peptide in your answer.
HbA: Val-His-Leu-Thr-Pro-Glu-Glu-Lys
HbS: Val-His-Leu-Thr-Pro-Val-Glu-Lys
Yes The two peptides will separate from each other in an electric field when the pH is 7.0
The two peptides wil drift/separate from each other when the pH is 7.0 because of the reaction of trypsin enzyme and also the difference in charge between HbA and Hbs
Considering charge of each peptide
Since The isoelectric point of normal Hba is 6.9 and Hbs possess two fewer negative charges per hemoglobin molecules
The Hbs is more hydrophobicity than HbA due to the substitution of glutamic acids of HbS by valine residue.
Considering Electrophoresis
At a lower pH level Hbs shows a slower moving band than Hba
while a higher pH level the HbS peptide is less negatively charged while the carboxyl group of HbA is more negatively charged and Hba moves faster as well as an acidic pH.
Hence we can conclude that the two peptides will separate from each other in an electric field when the pH is 7.0

How does the carbon stored in the bodies of living organisms move into rocks?(1 point)
Carbon dioxide released through respiration dissolves in certain rocks, like limestone.
Living organisms decay, releasing carbon into the soil, and soil is compacted into rocks.
Living organisms decay and become fossils fuels, which eventually become rocks.
Carbon dioxide dissolves in ocean water and is slowly absorbed by rocks in the ocean.
In the atmosphere, carbon is stored in the form of gases, such as carbon dioxide. ... This carbon can then be ingested and stored in animals that eat the plants. When the animals die, they decompose, and their remains become sediment, trapping the stored carbon in layers that eventually turn into rock or minerals.
When animals die, their bodies degrade into the soil, encasing the carbon in layers that eventually transform into rock or minerals. hence option b is correct.
What is rock?Stone including limestone and its minerals is created when sediment and shell layers are bonded together over time.
Gases like carbon dioxide are among the forms of carbon that are stored in the atmosphere. Animals that consume the plants can then absorb and store this carbon.
When animals die, their bodies degrade into silt, encasing the carbon in layers that eventually transform into rock or minerals. Some of this silt may eventually turn into fossil fuels like coal, oil, or natural gas, which when burned, release carbon back into the atmosphere.
Therefore, when an animal dies to decompose into the soil which becomes rocks through carbon from living organisms moves into rocks, hence option b is correct.

vermiform appendix is a vestigial organ in human being give reason.
Answer:
The human appendix may be considered as a vestigial organ as it has been proved that the removal of the organ after infancy does not create any harm. Vestigial in that sense means that the vermiform appendix seemingly has no functions or is useless now but they might have had functions previously which are lost someway due to evolution.
Explanation:
Vestigial organs are organs, tissues or cells in a body which are not functional anymore the way they were in their ancestral form of the trait. It is therefore authentication of evolution and hence were helpful in explaining adaptation.

Which of the following is a sign of food spoilage?
-a. Soil on unwashed vegetables
-b. Bruised fruit
-c. Bulging or leaking cans
-d. Cloudy egg whites (albumin)
The sign that shows food spoilage is bulging or leaking cans. That is option C.
Food substances can be stored or preserved to prolong the nutritive values and shelf life of the food.
Food spoilage occurs when environmental factors such as:
Light, oxygen, heat, humidity, temperature and spoilage bacteriacauses food to become unsuitable for consumption.
For canned products, bulging or leaking cans shows the food content has deteriorated.
This shows some ongoing fermentation by a spoilage bacteria causing the can to bulge and eventually leak out.
Therefore, the sign that shows food spoilage is bulging or leaking cans.
