How much of the energy (what percentage) of oxidizing Glucose to Pyruvate is captured in Catabolism as NADH ( H ) and ATP?
Answer:
40 percent.
Explanation:
About 40 percent of energy as ATP is produced due to oxidizing Glucose molecule in the process of respiration while the remaining 60 percent is lost as heat energy which is responsible for the generation of high body temperature. One molecule of glucose produces four molecules of ATP, two molecules of NADH, and two molecules of pyruvate during the first stage of respiration known as glycolysis while in the end of respiration process only ATP, carbondioxide gas and water is produced.

Explain why it makes sense to use the word translation to describe protein synthesis and why it would not make sense to use the word translation to describe mRNA synthesis?
Answer:
The application of the word translation makes sense at the time of describing the synthesis of protein as the language of nucleic acids is transformed into the language of polypeptides by the phenomenon of translation. On the other hand, it will not be suitable to describe the synthesis of mRNA using the word translation as the nature of the biomolecule stays similar because both the DNA and the product of DNA, that is, mRNA are nucleic acids.

what is the difference between bracketed key and indented key?
Answer:
Bracketed and indented keys are two dichotomous/or branching keys with an ordered, numbered couplet, and spatially differentiated respectively.
Explanation:
Dichotomous keys are used in the identification and classification of taxa.
Bracketed keys, or parallel keys, are easy to understand- for efficiency, these keep the first two entries of every couplet or pair being compared. It also makes use of a numbering system in the couplet choices for easy tracking.
Indented keys maintain an equal distance from the margin on the left of the pages. Successive couplets are indented til the taxon is identified.

In man, glucose is present in blood plasma but not in urine. This is because glucose
molecules are
(A) actively transported from the proximal convoluted tubule to blood capillaries
(B) oxidised to supply energy for ultrafiltration
(C) stored in the kidney
(D) too large to enter Bowman's capsule
In man, glucose is present in blood plasma but not in urine. This is because glucose molecules are actively transported from the proximal convoluted tubule to the blood capillaries.
What is glucose?Glucose is a monosaccharide, biomolecule found in ingested food which is used to provide energy to the cells of the body. Glucose is usually found only in the blood, since it is reabsorbed in the renal tubules, but when there are pathologies in which glucose levels in the blood are increased, the sites that reabsorb glucose become saturated, thus having an escape of glucose in urine.
Therefore, we can confirm that in man, glucose is present in blood plasma but not in urine. This is because glucose molecules are actively transported from the proximal convoluted tubule to the blood capillaries.

An organism is exposed to a mutagen, such as X-rays or ultraviolet light. What could be the effect of the mutagen on the organism? Select all of the answers that apply.
The mutagen may disrupt gene function to the harm of the organism.
B. The mutagen may change gene function in a way that benefits the organism.
C. The mutagen may change the genetic material of the cell from DNA to proteins.
D. The mutagen may change the binding between codons and anticodons.
E. The mutagen may have little or no observable effect on the organism.
Answer:
a, b, c, e
Explanation:
- since mutations are random, they could both harm or benefit or have no effect on the organism (depends on where in the DNA is mutated, on the type of mutation that occurs, on whether the mutation is fixed, etc.)
- the binding between codons and anticodons are always as follows:
A on mRNA binds to U on tRNAT on mRNA binds to A on tRNAG on mRNA binds to C on tRNA and vice versaMutagens are substances that damage DNA and can cause permanent changes in the DNA sequence, depending on the ability of the organism to fix the mess.
Mutagen's effect:Deoxynucleoside triphosphates (dNTPs), which are utilized by DNA polymerases to duplicate DNA, can also be damaged by DNA-damaging agents.
A mutagen could harm the organism by disrupting gene function.A mutagen may alter gene function to the organism's benefit.A mutagen can alter codon-anticodon binding.Therefore, the final answer is "Option A, B, and D".

There are 40 chromosomes in germ cells of a ferret. How many sex chromosomes are there in a ferret's ovum?
Answer:
Explanation:
In a mitotic cell division, the number of chromosomes remains constant. It is so because the chromosomes are replicated to produce chromatid which during cell division is equally distributed in all the daughter cells thereby preserving the chromosome number.Both sperm cell and ovum have 23 chromosomes each. It is the fusion of both at fertilization that brings about 46chromosomes seen in somatic cells. These chromosomes are 22pair somatic chromosomes and a pair of sex chromosome (I.e XX or XY).The cells of the body have a diploid number of chromosomes (2N). The diploid number is usually double the haploid number (1N), so if the haploid number of chromosomes is 20, then 2x20=40. So the answer either 40 or 36
To determine the number of sex chromosomes that are there in a ferret's ovum is 2 sex chromosomes.
Given the following data:
Number of chromosomes = 40 chromosomes.Sex chromosomes can be defined as a pair of chromosomes that are responsible for determining the gender of a living organism i.e whether an organism is either male or female.
To determine the number of sex chromosomes that are there in a ferret's ovum:
Mathematically, the number of chromosomes in an organism is given by the formula:
[tex]Chromosomes = 2N[/tex]
Where:
N is the number of sex chromosomes.Substituting the given parameter into the formula, we have;
[tex]40 =2N\\\\N=\frac{40}{2}[/tex]
N = 2 sex chromosomes

Which sequence describes the formation of a gamete?
A.transcription → replication → translation
B.replication → cell division I → cell division II
C.mitosis → cell division I → translation
D.cell division I → cell division II → transcription
Answer:
part c
Explanation:
The sequence replication → cell division I → cell division II describes the formation of gametes.
Where does the formation of gametes occur?Meiosis (reduced division), in which a germ cell splits into two pieces and produces four gametes, is the process by which gametes are created.
Meiosis is a type of cell division that results in the production of four gamete cells and a 50% reduction in the number of chromosomes in the parent cell.
The gonads are where gametes (germ cells) are made. This process is known as spermatogenesis in males and oogenesis in females. The majority of novel mutations arise during gametogenesis, however males exhibit a higher mutation rate.

The texture of igneous rock that is composed of large mineral grains
During G2 the Wee1 protein phosphorylates tyrosine-15 of the Cdc2 protein kinase, thus inactivating it. Only once dephosphorylation occurs and Cdc2 becomes active carn the cell pass from G2 into M and proceed to cell division. Can you think of a reason why the Wee1 protein was named as such?
Answer:
cells can't fully grow in Wee1 mutants
Explanation:
The G2 phase is a period where cell growth and proteins are synthesized to prepare for cell division. The Wee1 protein is a dosage-dependent inhibitor of mitosis. Moreover, the cyclin-dependent kinase 2 (cdc2) is a protein involved in the regulation of the cell cycle which phosphorylates serine residues in Wee1. However, in Wee1 mutants, Cdc2 is not inactivated (phosphorylated). This change causes cells to enter M phase prematurely, thereby producing "wee" mutant cells.

Calculate the amount of energy you would expect to find at the secondary consumer level if there were 100,000 J of energy at the producer level in an ecosystem.
The amount of energy one would expect to find at the secondary consumer level if there were 100,000 J of energy at the producer level in an ecosystem is 1000J.
How to calculate amount of energy available in food chain?The food chain is a feeding relationship between living organisms in an ecosystem. Each organism occupies a position called trophic level.
The trophic levels involved in a food chain are as follows:
ProducerPrimary consumersSecondary consumersTertiary consumerThe producer begins the energy transfer, however, only 10% of the available energy is passed to the next trophic level because 90% of this energy is used for metabolic activities.
This means that if 100,000 J of energy is available at the producer level in an ecosystem, the following applies:
Primary consumers: 10/100 × 100,000 = 10000J of energy Secondary consumers: 10/100 × 10,000 = 1000J of energyTherefore, the amount of energy one would expect to find at the secondary consumer level if there were 100,000 J of energy at the producer level in an ecosystem is 1000J.
