Explanation:
Animals and plants use the chemical energy stored carbohydrates to fuel their own life processes, ultimately breaking down these carbohydrates into carbon dioxide, water, and heat in a process called aerobic respiration. The heat that is released from aerobic respiration dissipates into the environment. From this information, which of the examples of kinetic energy are:______
Answer:
A good example happens during the breakdown of food particles.
Explanation:
The chemical energy stored in food is a type of potential energy. Transformation of this energy into kinetic energy happens during chemical reactions that takes place during digestion. A good example of kinetic energy is therefore the breakdown of carbohydrates into carbon dioxide, water and heat.
Using the Gizmo, determine how coal and petroleum (oil) are formed. Describe the steps required to form each fuel from atmospheric CO2.
Answer and Explanation:
Petroleum and coal are fossil fuels. The degradation of the earliest plants forms them. These dead plants started to pile up and form peat. Then the pressure and heat from various geological procedures convert peat into coal. Coal is a combustible rock which contains 50% carbon. Anthracite, Lignite and bituminous are the types of coal, and the formation of coal depends upon the quantity of hydrogen, oxygen and carbon. Petroleum exists naturally in liquid form and formed by decomposed organic matter. Fossil fuels can be refined into usable substances. Gasoline, tar, lubricants and many other products are obtained from petroleum. There are two steps, which required to form fuel from atmospheric carbon dioxide. In first step carbon dioxide is converted into carbon monoxide. In the second step, carbon monoxide combines with hydrogen to form hydrocarbon fuels. The formation of fuel is a natural process when animals respire carbon dioxide release in the atmosphere.

What is the difference between sleet and hail? What conditions are needed to make each?
Answer:
Sleet forms in winter storms, while hail is a warm-season type of precipitation. As noted above, sleet forms when snow melts in a warm layer and then refreezes into ice pellets as it falls though a cold layer. Hail, however, forms in spring, summer or fall thunderstorms.

what is some advice you would give to someone who doesn’t know the importance of carrying capacity
Answer:
For someone who doesn't know the importance of carrying capacity, i would advice him to understand what carrying capacity mean, and then tell him that he should not overcrowd the population of animals or be part of humans overcrowding as it can destroy the ecosystem or resources.
Explanation:
This is because, carrying capacity is the population size that can conviniently live in an habitat with the available resources..
It's very important because, it will ensure that the population size that the resources can sustain can live in the environment so as to prevent degradation of the ecosystem or the environment due to increase in population size.

significance of active transport in food processing
Answer:
Why do we need active transport?
Moving Against a Gradient
Small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances that living cells require in the face of these passive movements. A cell may spend much of its metabolic energy supply maintaining these processes.

Which is the classification of any naturally occurring solid inorganic substance characterized by a crystal structure? A. fossil B. metal C. mineral D. rock
Answer:
C. mineral
Explanation:
In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states. The three (3) classical states of matter are;
1. Liquid: is the state of matter in which the physical substance can be poured and takes the shape of its container. Also, liquids generally have a definite volume. Examples of liquids are urine, water, milk, blood etc.
2. Gas: is the state of matter in which the physical substance has no definite shape or volume and as a result fills all available space. Also, gases are easily compressible, takes the shape of its container and can flow. Examples of gases are hydrogen, oxygen, argon, nitrogen etc.
3. Solid: is the state of matter in which the physical substance has a definite shape and fixed volume but not compressible. Examples of solids are pen, screwdriver, television, car etc.
Mineral is the classification of any naturally occurring solid inorganic substance characterized by a crystal structure. Also, minerals are homogeneous in nature with a defined chemical composition and characterized by a crystal structure comprising of ions, atoms, or molecules in an orderly arrangement.
Some examples of minerals are iron, copper, aluminum, tin, coal, quartz, feldspar, mica, etc.
Which cell is a plant cell?
Answer:
b
Explanation:
Suppose DNA polymerase synthesizes DNA at a rate of 1000 bases per minute in a newly discovered bacteria and that bacteria replicates 50% of their chromosome every 40 minutes. Calculate the total number of nucleotides in the bacterial chromosome.
Answer:
320000 nucleotides
Explanation:
Given that:
The rate of synthesis by DNA polymerase = 1000 bases per minute
The time taken to replicate 50% of their chromosome = 40 min
Thus, the time taken for one complete round of replication = (40 × 2) min
= 80 min
∴
The total number of nucleotides in the newly synthesized strand = 1000 pairs/min × 80 min × 4
= 320000 nucleotides
The total number of nucleotides in the bacterial chromosome is equal to 80000 bp (80 kb).
Bacteria are prokaryotic microorganisms whose genome consists of a single circular chromosome.In this case, it is possible to obtain the duration of DNA replication from data:
40 minutes (min) >> 50% bacterial chromosome40 x 2 = 80 minutes (min) >> 100% bacterial chromosomeThe length of the bacterial chromosome can be easily calculated:
DNA replication rate = 1000 base pairs (bp) per minuteTotal chromosome length: 80 x 1000 bp = 80000 base pairs (bp)A kilobase (kb) is equal to 1000 base pairs (bp) of DNA, thereby in this case the bacterial genome is equal to 80 kb.In conclusion, the total number of nucleotides in the bacterial chromosome is equal to 80000 bp (80 kb).

Answer:
Explanation:A. Photosynthesis
Answer: a photosynthesis
Explanation:
After a successful launch and return of a rocket, NASA and SpaceX noticed a strange gel like substance on the wing. Under the microscope the strange thing has fibers, but no cells. When introduced to water the substance tends to move around. When exposed to warm temperatures it seems to grow in mass.
nonliving the heat from the hot plate is causing the gel like substance to move it's the same thing with liquid nitrogen how it seems to bounce off the floor it's because liquid nitrogen is super cold and the heat basically excites the electrons in the liquid nitrogen making it bounce off the floor same with the gel like substance the electrons in the gel substance are getting excited by the heat and jumping up and down but the substance itself is not alive

An experiment would be more appropriate method to investigate whether meditation is effective in lowering blood pressure because experiment has a control group as well as a testable group. Due to control group and testable group, we can easily find out the effect of meditation in lowering blood pressure if we apply meditation techniques to the testable group and compared it with the control group, we get results.
3. What happens during each of the four phases
of mitosis? Write one or two sentences for
each phase
Answer:
After DNA replicates and the cell is about to divide, the DNA condenses and coils into the X-shaped form of a chromosome. During this process, sister chromatids separate from each other and move to opposite poles of the cell. This happens in four phases, called prophase, metaphase, anaphase, and telophase.
Mitosis is a process of division in which a parent cell is divided to form two identical daughter cells.
Mitosis completes into 4 steps:
Prophasemetaphaseanaphasetelophase.What is the process of mitosis?The process of mitosis division completes into four stages:
Prophase – The chromosome is condensed and compact. The spindle fiber forms.Metaphase – The nuclear membrane dissolve, and the spindle fiber aligns all the sister chromatids (chromosome) in one line.Anaphase – The sister chromatids separated from each other and centromere. The spindle takes each strand to the opposite pole.Telophase – the nuclear membrane appears again around each set of the chromosome. The chromosome uncoil and the cytoplasm divide into two cells, and this process is called cytokinesis.Thus, this is the process of mitosis.
