What are the energy producing organelles and under what conditions do they produce energy
Answer: mitochondria are the site of aerobic respiration, for which of course, they require oxygen.
Explanation: mitochondria are the site of aerobic respiration and energy production for which they require a supply of oxygen
The energy-producing organelle is the mitochondria, and the mitochondria make the energy in the aerobic cellular respiration where the cell uses oxygen and makes the energy that is the ATP.
What is the function of the mitochondria?The mitochondria are cellular organelles in which energy is produced, which happens when the cell gets enough oxygen and the glucose is broken down completely to form ATP. The ATP is formed due to the proper oxygenation of the glucose, and the proton gradient is formed. The proton gradient gives the energy to the cell for energy production, and the energy is used by the cell for the overall body metabolism and growth.
Hence, the energy-producing organelle is the mitochondria, and the mitochondria makes the energy in the aerobic cellular respiration where the cell uses oxygen and makes the energy that is the ATP.

What happens to the amount of energy as it moves up through an energy pyramid?
A. Some of the energy is lost.
B. Organisms double their energy as they move up the pyramid
C. Energy is transferred from the top to the bottom
D. The energy levels stay the same
Answer: some energy is lost from the pyramid, energy is transferred from bottom (producers) to top, but in decreasing amounts.
Explanation: total energy is conserved, but not necessarily within the energy pyramid, which is an open system where energy is lost from the pyramid, mainly as heat but also as sound.
Energy is transferred up the pyramid but the amount transferred at each stage is less because of losses outside the pyramid.

Which of the following is false about DNA?
A. DNA is made up of units called nucleotides.
B. Any base can pair to any other base.
C. DNA contains the instructions to make proteins.
D. DNA is found in a cell's nucleus.
Answer:
b. any base pair can pair to any other base
Explanation:
Any base pair cannot pair with any other base, Adenine pairs with thymine and cytosine pairs with guanine.
• The hereditary material in humans and almost all of the living species is known as DNA or deoxyribonucleic acid.
• The majority of the DNA is present within the nucleus of the cell.
• DNA comprises the instructions to make proteins that helps to perform essential functions within the body of an organism.
• Within the DNA, information is stored in the form of a code formed of four chemical bases, that is, Adenine, guanine, cytosine, and thymine.
• The base pairs present within the DNA pairs up with each other, that is, adenine pairs with thymine only, and guanine pairs with cytosine, no other kind of pairing is found within the DNA. Each base of also attached with a molecule of phosphate and sugar.
• Together, a phosphate, base, and sugar are known as a nucleotide.

In other words, how are we speeding up the effects of the competitive exclusion principle and thereby altering the outcome of that ecosystem's natural succession
Answer: Overgrazing, overfishing, and forest fires
Explanation:
Competitive exclusion principle two species which have the same ecological niche cannot exists together as such species will be competing for the same resources. The species which is superior over the other will receive the resources and the other species having no competitive advantage will not survive in future.
According to the given situation, human being is the most superior species on earth and have competitive advantage of thinking ability and intelligence over other species. Succession are the changes that occur in the biotic community of an ecosystem with respect to time.
The human beings can speed up the effects of the competitive exclusion principle by various ways: Overgrazing, overfishing, and forest fires. The overgrazing of the cattle in the field can remove the vegetation cover of the region and the land will become barren so instead of progressive succession in terms of vegetation cover the succession will again re-initiate in terms of primary succession if environment supports.
Overfishing can cause the exclusion of some valuable species of fish and there will not be evolution of such species and will alter the outcome of natural succession.
Forest fires can affect both floral and faunal species some species may tolerate the fire and will survive and some precursors like roots of the plants can support new individual plants. This will again alter the outcome of natural progressive succession in an ecosystem.

In tomatoes, a heterozygous plant with normal fruit and purple stems is crossed with a recessive plant having fasciated fruit and green stems. The following distribution of offspring is observed:
normal fruit, purple stems 38.5% fasciated fruit, green stems 38.5%
normal fruit, green stems 11.5%
fasciated fruit, purple stems 11.5%
What conclusion can be made regarding the loci for fruit shape and stem color? HINT determine the RF
What the loci and RF here mean? How to answer this question?
Answer:
Recombination frequency, P = 0.23.
If the recombination frequency is < 50%, genes are linked. A RF of 23% tells us that these two genes are in the same chromosome, close enough to be linked.
1% of recombinations = 1 map unit23% = 23 map unitsThe genes for stem color and fruit type seem to be in the same chromosome, linked and 23 MP apart.
Explanation:
In the present example, the genes for stem color and fruit type seem to be linked.
To know if two genes are linked, we must observe the progeny distribution. If individuals, whos genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1. If we observe a different distribution, that is that phenotypes appear in different proportions, we can assume that genes are linked in the double heterozygote parent.
In this way, we might verify which are the recombinant gametes produced by the di-hybrid, and we will be able to recognize them by looking at the phenotypes with lower frequencies in the progeny.
The following distribution of offspring is observed:
normal fruit, purple stems 38.5% fasciated fruit green stems 38.5% normal fruit, green stems 11.5% fasciated fruit, purple stems 11.5%38.5% + 38.5% + 11.5% + 11.5% = 100%
N (total number of individuals in the progeny) = 100
number of individuals with normal fruit, purple stems 38.5 number of individuals with fasciated fruit green stems 38.5 number of individuals with normal fruit, green stems 11.5 number of individuals with fasciated fruit, purple stems 11.5To calculate the recombination frequency we will make use of the next formula: P = Recombinant number / Total of individuals. The genetic distance will result from multiplying that frequency by 100 and expressing it in map units (MU).
P = Recombinant number / Total of individuals.
P = 11.5 + 11.5 / 100
P = 0.23
We need to know that 1% of recombinations = 1 map unit = 1cm. Also, the maximum recombination frequency is always 50%. This means that if the recombination frequency is < 50%, genes are linked. A RF of 23% tells us that these two genes are in the same chromosome, close enough to be linked. FR 23% = 23 UM.

the image of an object which is 10cm from a lens is formed on the same side as the object. If the image is 10cm behind the object, Find the focal length of the lens.
Answer:
Focal length is 6.67 cm.
Explanation:
Object distance, u, from the lens = 10 cm
Image distance, v, to the lens = 10 cm + 10 cm
= 20 cm
Apply the lens formula to determine the focal length, f, of the lens.
[tex]\frac{1}{f}[/tex] = [tex]\frac{1}{u}[/tex] + [tex]\frac{1}{v}[/tex]
= [tex]\frac{1}{10}[/tex] + [tex]\frac{1}{20}[/tex]
= [tex]\frac{2 + 1}{20}[/tex]
[tex]\frac{1}{f}[/tex] = [tex]\frac{3}{20}[/tex]
Find the inverse of both sides, so that;
f = [tex]\frac{20}{3}[/tex]
= 6.67
f = 6.67 cm
The focal length of the lens is 6.67 cm.

Drag the inputs and outputs of cellular respiration to their correct
place.
Answer:
Inputs are: Glucose
Output are; carbon dioxide, ATP and heat
Explanation:
Cellular respiration is the metabolic process by which cells of living organisms breakdown glucose molecules to release energy (ATP). Cellular respiration, which is a must for every living organism uses oxygen (aerobic) to break down glucose (C6H12O6) into carbon dioxide (CO2) and water (H2O).
Based on the question asked, the inputs of cellular respiration are GLUCOSE AND OXYGEN while the outputs are CO2, H2O, ATP and HEAT give out. The general chemical equation is as follows:
C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

gene expression is a regulated process due to the fact that-
Answer:
-almost all the cells of your body contain the exact same DNA.
Explanation:
Gene regulation is how a cell controls which genes, out of the many genes in its genome, are “turned on”.
Answer:
Genes are regulated to preserve energy and space.
Explanation:
The process of expressing genes is an energy-requiring process since it requires the breaking and synthesis of proteins. When genes are regulated energy is saved as only the gene required to perform a certain job is turned on and after the function is completed it is turned off. Therefore, continuous protein synthesis is not required to express the genes at all times.If the genes were not regulated i.e., turned off and turned on at required times then it would take a never-ending spree of gene expression which in turn would require a lot of time in transcription and translation.For more information:
