Answer:
Man (dimples and freckles) - FfDd
Woman (no dimples and no freckles) - ffdd
Child (no dimples and no freckles) - ffdd
Explanation:
According to this question, the possession of freckles (F) and dimples (D) are the dominant traits. The union of a man with dimples and freckles and a woman with no dimples and freckles (ffdd) gave rise to a child that has no dimples or freckles (ffdd).
Since the child has a recessive 'ffdd' genotype, it means that the father will likely have a heterozygous genotype (FfDd). Therefore, the genotypes of the three persons involved are;
- Man (dimples and freckles) - FfDd
- Woman (no dimples and no freckles) - ffdd
- Child (no dimples and no freckles) - ffdd

Complete tetanus occurs when the muscle is stimulated repeatedly at a high rate, eliminating a relaxation phase, the amount of tension gradually increases to a steady maximum tension.
What is Complete tetanus?A tetanic contraction is also called as tetanized state, tetanus, or the physiologic tetanus, the latter is used to differentiate from the disease called tetanus, which is a sustained muscle contraction that is evoked when the motor nerve which innervates a skeletal muscle emits action potentials at a very high rate than usual action potential production rate.
Complete tetanus is also called fused tetanus. It occurs when the frequency of stimuli increases still further than normal. In this case, the individual muscle contractions completely fuse to produce one large enough muscle contraction in the body.

Describe how human activities cause desertification including desertification’s impacts on soil and the role of modern agriculture in causing Desertification.
Answer:
Desertification is the destruction of the biological potential of the land and it is generally viewed as an advanced stage of land degradation. human activities also cause the process such as poor irrigation practices, deforestation, the expansion and intensive use of agricultural lands, and overgrazing.
Such human activities put enormous pressure on the land by altering its soil chemistry and hydrology. Modern agriculture causing a negative impact on the soil and land by overexploiting the biological and chemical potential of the land.

Mass of the moon is 7.4x10^22 kg and its radius is 1740km, Calculate the value of acceleration due to gravity on the surface of the moon. *
Answer:
The gravitational acceleration in the surface of the moon is 1.63 m/s^2
Explanation:
The gravitational acceleration at a distance R of an object of mass M, is given by:
g = G*M/R^2
Where:
G is the gravitational constant.
G = 6.67*10^(-11) m^3/(kg*s^2)
We could think that all the mass of the moon is at its center, then at the surface of the moon, the distance will be equal to the radius of the moon, thus:
R = 1740km
But we want to work with meters, so remember that:
1km = 1000m
then:
1740km = (1740)*1000m = 1740000m
R = 1740000m
And the mass is just:
M = 7.4x10^22 kg
If we input all that in the gravitational acceleration equation, we get:
g = (6.67*10^(-11) m^3/(kg*s^2))*(7.4x10^22 kg)/( 1740000m)^2
g = 1.63 m/s^2
The gravitational acceleration in the surface of the moon is 1.63 m/s^2

gene has a base sequence that starts with: TAG CAT GGC AT.
A) The gene has a point mutation and is changed to the sequence below : TAG CTT GGC AT. What kind of mutation is this?
B) What is the new mRNA strand formed by this gene?
C) What are the new amino acids formed from this gene?
D) Describe how the mutation has affected the protein coded by this gene.
Answer:
A. Substitution mutation
B. AUC GAA CCG UA
C. Isoleucine- Glutamic acid- Proline
D. It will lead to formation of a different protein
Explanation:
According to this question, the gene has a base sequence that starts with: TAG CAT GGC AT but undergoes a kind of point mutation to become; TAG CTT GGC AT.
A. From the observation of the two base sequences, base A is substituted for base T in the second Codon i.e. CAT to CTT. This is an example of SUBSTITUTION MUTATION because it involves the replacement of a base nucleotide by another.
B. Following transcription, which is the synthesis of mRNA from a DNA template, the mRNA sequence from the mutated sequence is as follows: AUC GAA CCG UA
C. Following translation using the genetic code, the amino acid sequence that will result from the mutated sequence is as follows: Isoleucine- Glutamic acid- Proline
D. Due to the change in nucleotide base of a codon, a change in the amino acid sequence has occured. Hence, this will lead to the formation of a different protein.
There are two strains of E. coli, let's call them
strain A and B. Both are his- mutants. A his-
mutant is unable to synthesize the amino acid
histidine. Both strains are unable to grow on
chemically defined media if the media is not
supplemented with histidine. Careful analysis of
strain A demonstrated that the mRNA for
histidine genes is transcribed but not translated.
No histidine mRNA was present in the cytosol of
strain B. How is this possible?
Answer:
Strain A is subject to posttranscriptional gene silencing, whereas Strain B is subject to transcriptional gene silencing
Explanation:
During transcription, a segment of DNA (e.g., a gene) is used as a template to synthesize a complementary RNA molecule, typically a messenger RNA (mRNA) molecule, which is in turn used as a template to synthesize a polypeptide chain (i.e., a protein) by a process known as translation. In consequence, gene expression involves two different processes (i.e., transcription and translation), by which genetic information contained in DNA flows from genes to proteins. Transcriptional silencing refers to the phenomena by which the transcription of one or more genes (in this case, the genes necessary for histidine biosynthesis) are repressed or not, dependent only on the gene's chromosomal location, whereas posttranscriptional silencing occurs when transcripts do not accumulate in spite of continuous mRNA transcription. In this case, mRNA synthesis is expected to occur in strain A his-mutants (i.e., strain A is subject to posttranscriptional gene silencing), whereas mRNA synthesis is not expected to occur in strain B his-mutants (i.e., strain B is subject to transcriptional gene silencing).

Plants as well as brown, green, and red algae show a basic life cycle which involves the alternation of generations between a(n) egg and a sperm. seed and a cone. spore and pollen. megaspore and a microspore. sporophyte and a gametophyte.
Answer:
The correct answer is ''sporophyte and a gametophyte''
Explanation:
Plants have a diplohaplon life cycle: a haploid adult plant, called a gametophyte, and a diploid adult plant, called a sporophyte. In green algae, the two generations, sporophyte and gametophyte, are independent and generally the same size. This type of life cycle is found not only in many multicellular green algae, but also in brown algae and red algae. In vascular seedless plants, including ferns, gametophytes, although still independent, are smaller in size than sporophytes. In seed plants, the gametophytic generation is further reduced and is totally dependent on the sporophyte.

The enzyme lactate dehydrogenase is responsible for fermentation of pyruvate to form lactate. This process occurs in red blood cells and in muscle cells during intense exercise. Why is fermentation a necessary process for these cells to meet their energy needs
Answer:
Fermentation is a process that happens in the absence of oxygen and it involves the conversion of Pyruvate to lactate.
Cells in the body need constant energy supply to cater for the various demands of our everyday activities and to ensure that they function optimally.
Oxygen supply is an important factor in ATP generation and in cases where there is a lack of it the body system adjusts itself to produce the energy anaerobically. This usually involves the conversion of pyruvate to lactate which aids the breakdown of glucose thereby supplying it to cells of the body.

Explanation:
What is the fate of pyruvate in the cytoplasm when oxygen is absent
Answer:
Pyruvate is turned to lactate via a process called fermentation
Explanation:
Pyruvate is the product of the initial stage of cellular respiration called GLYCOLYSIS. Pyruvate is produced in the cytoplasm where glycolysis occurs. The fate of pyruvate i.e. what will eventually happen to pyruvate, is determined by the presence or absence of oxygen.
In the absence of oxygen i.e. anaerobic condition, pyruvate is converted into lactate in a process called FERMENTATION. The NADH produced during glycolysis is reoxidized to form NAD+ in the process.
