Answer:

Bacteria have smaller populations, grow faster, and also share more genes compared to mammals.

Explanation:

Because bacteria reproduce quicker and are also in smaller populations, they can evolve quicker because more genes are shared which can be helpful. This is due to natural selection, which will affect bacteria more than mammals because their small populations will make natural selection more significant to  be harmed by mutations and allow them to evolve.

Given structure is that of a virus, which includes the viral capsid, nucleic acid, etc.

A= spike

B= Envelop

C= Nucleic acid

D= Capsid

Small infectious agents known as viruses can multiply only in the living cells of other animals. They are composed of genetic material, which can be DNA or RNA, encased in a protein shell called a capsid. Some viruses also have a lipid-based outer coat.

Because they cannot perform metabolic functions on their own and require a host cell to reproduce, viruses are not considered living organisms. They spread infection to various living things including bacteria, plants, animals and people.

A virus replicates its genetic material and forms new viral particles when it infects a host cell using the host cell's machinery. This can lead to the death of the host cell and result in the spread of the virus to other cells of the host.

Therefore, given structure is that of a virus, which includes the viral capsid, nucleic acid, etc.

Answer:

In strict mode, the narrow-sense heritability is the proportion of the additive genetic variance that contributes to the total of the phenotypic variance. This value can be associated with the inheritance of the a-thalassemia .

Explanation:

A-thalassemia is a genetic disorder caused by mutations affecting four different genes that encode alpha-globin, thus affecting the hemoglobin production process and, consequently, oxygen transport. The mode of inheritance of the a-thalassemia may be associated with narrow sense heritability since the phenotype is manifested by gradation, i.e., each allele might contribute in similar mode to this genetic condition.

Explanation:

The next step in this experiment is constructing a hypothesis and recording data. The correct option is (C).

Making observations and keeping track of data would be the experiment's next phase. The learner would observe and record the ripening of both apples at locations A and B in this stage. They would have to keep track of the maturity of the apples throughout time by routinely observing and recording the changes. This could entail examining the apples visually for color, texture, and overall maturity and recording any variations between the apples at locations A (by themselves) and B (next to a banana).

The student can analyze the results and develop conclusions regarding the impact of bananas on the maturity of other fruits by gathering information on the ripening of the apples in both locations. The information can be used to prove or disprove the initial theory and assist determine whether bananas actually influence the maturity of surrounding fruits.

Answer:

C-12 > C-13 > C-14,O-16 > C-16,O-18

Explanation:

Generally, isotopes are described as atoms of the same elements with the same atomic number but different number of neutrons.

Hence,

For O-18, oxygen has an atomic number of 8 and neutron number of 10.

For C-14, carbon has an atomic number of 6 and neutron number of 8.

For C-13, carbon has an atomic number of 6 and neutron number of 7.

For C-16, carbon has an atomic number of 6 and neutron number of 10.

For carbon 12, carbon has an atomic number of 6 and neutron number of 6.

For O-16, oxygen has an atomic number of 8 and neutron number of 8.

Hence the rank from the fewest neutrons would be C-12>C-13>C-14,O-16>C-16,O-18

Explanation:

Mutation can cause a change in DNA to change in many ways.

Mutation is the sudden change in the genome of an organism that can be heritable from parent by their offspring.

Missense mutation - This occur when a base pair is substituted for by another leading to the formation of an entirely new amino acid.

Nonsense mutation - This occurs when a base pair is substituted for by another leading to the formation of a new amino acid. The new amino acid form therefore send a stop signal to the sequence of amino acid been built.

Insertion or deletion - Insertion mutation inserts new base pair into the sequence changing the number of the DNA base while deletion deletes a base pair changing the number of DNA base from the amino acid sequence.

Answer:

Point Mutations

A point mutation—the change of a single nitrogen base in a DNA sequence—is usually the least harmful type of DNA mutation

Answer:

The complete steps are:

1. Body needs energy for activity

2. body releases epinephrine

3. epinephrine binds to fat cells in adipose tissue

4. triacylglycerols (triglycerides) are hydrolyzed to glycerol and fatty acids

5. Fatty acids transported to tissue

Explanation:

Mobilization of fat is a gluconeogenetic process (a process that sequesters energy from a compound other than carbohydrates), in which fat molecules in the adipose tissues are metabolized for energy production.

The process starts when the body is in an energy-deprived (hypoglycemic) state, leading to the release of glucagon by the pancreas and the release of epinephrine (adrenaline) from the adrenal medulla of the brain.

These hormones activate gluconeogenesis and glycogenolysis (breakdown of glycogen) in the liver, it also activates lipolysis in the muscle cells and liver, as well as inhibiting fatty acid synthesis. This is mediated through the binding of these hormones to specific receptors on the surface of fat cells, leading to the activation of lipases (enzymes catalyzing lipolysis). Lipases catalyze the hydrolysis of triglycerides (common fat in diets) to glycerol and three molecules of free fatty acids. These free fatty acids are released into the blood where they attach to serum albumin; a protein for transporting the hydrophobic fatty acids to the muscle cells where they are taken up and utilized to produce energy and C0₂.

THE DGR AN represents deletion mutation

THE RED ANA TRA N represents insertion mutation

THE FOX WTS RED represents substitution mutation

Explanation:

Mutation is a change in the nucleotide sequence of a gene. It can be of different types depending on how it occurs. A deletion mutation is that which involves the removal of one or more nucleotide base from the sequence.

An insertion mutation is the addition of one or more nucleotide bases to the sequence.

A substitution mutation is the replacement of one or more nucleotide base in a sequence.

The original sentences were:

1. THE RED ANT RAN

2. THE FOX WAS RED

3. THE DOG RAN

The three sentences that mutated/changed are:

1. THE DGR AN- in this sentence, letter O which represents one base is missing due to removal, making the original sentence (THE DOG RAN) alterated. Hence, this represents an example of deletion mutation.

2. THE RED ANA TRA N - in this case, Letter A has been added in between N and T. This makes the original sentence (THE RED ANT RAN) altered. Since addition of letter (base) occurred, this represents an example of insertion mutation.

3. THE FOX WTS RED - In this case, letter A in "WAS" was replaced by T, making the original sentence (THE FOX WAS RED) altered. Since a replacement of letter (base) is the case here, it represents an example of substitution mutation.

Answer:

POSITIVE CONTROL

c) Active Activator  

d) Active Repressor  

NEGATIVE CONTROL

f) Inactive repressor  

a) Inactive Activator  

b) cAMP

Explanation:

The positive controls are those groups in the experiment whose treatments are expected to confirm previously known results, thereby enabling the comparison of these results with the target group. In this case, both active activators and repressors are able to give results that can be compared with the test group  

The negative controls are those experimental groups where no response is expected. In this case, both inactive activators and repressors, and cAMP (which is a secondary messenger in diverse biological processes but is not involved in this pathway), are not expected to produce any measurable response.
