How are genetic relationships represented?
Answers
Answer:
Genetic relationships are analysed based on the comparison of allelic identity or differences, regardless of the number of SNPs that differ between two alleles of a gene, which simplifies the analysis.

Note:
In the attached files you will find the image of the three insects
Answer:
(i) Because they share the same genera, Vespula.
(ii) Because Morphologically, insects 1 and 2 are more alike than insect 3.
Explanation:
(i) Explain how the binomial names indicate that insects 1 and 2 are more closely related.
In taxonomy, many categories are used to aggregate organisms according to their evolutive relationship. These are Domain, Kindom, Clase, Order, Family, Genera, Species, Subspecies. All species might be recognized by their common name and their scientific name, which is more reliable. The binomial names of living beings indicate the scientific name by which the organisms can be recognized. A species scientific name is composed of two parts:
- Generic name or genera: correspond to many species that share common characteristics. In the example, Vespula is the genera
- Specific epithet: useful to identify each species in particular and differentiate organisms that are included in the same superior taxes. In the example, flavopilosa and rufa are the epithets that differentiate one species from the other.
According to this, we might assume that species 1 and 2 are more closely related because they share the same genera: Vespula. This suggests that they share more characteristics in common with each other than with Callicera.
(ii) Explain how the appearance of the three insects suggests that insects 1 and 2 are more closely related.
Morphologically, insects 1 and 2 are more alike than insect 3. Traits such as body shape, pigmentation pattern, antenna, wings, total body size, among others, are very similar in species 1 and 2. On contrary, species 3 is smaller, with a thinner antenna, different pigmentation patterns, different wings size and shape.

Concentration gradient
Answers
Answer:
Osmosis
Explanation:
Osmosis is the diffusion of water or gas molecules, from a region of higher concentration to a region of lower concentration, through a partially permeable membrane
Diffusion is the net movement of anything from a region of higher concentration to a region of lower concentration.
Plasmolysis is the process of shrinkage or contraction of the protoplasm of a plant cell as a result of loss of water from the cell.
The difference in the concentration of a substance between two areas is called the concentration gradient.

What syndrome does this karyotype show?
Answers
Answer:
C
Explanation:
The karyotype shown in the question is characteristic of Down syndrome, also known as Trisomy 21. Therefore option A is correct.
Down syndrome is a genetic disorder caused by the presence of an extra copy of chromosome 21, resulting in a total of 47 chromosomes instead of the typical 46.
The karyotype reveals three copies of chromosome 21, indicated as 47,XY,+21, which is indicative of Down syndrome in a male individual.
People with Down syndrome may experience developmental delays, intellectual disabilities, and characteristic physical features, such as almond-shaped eyes and a flat facial profile.
The presence of an extra chromosome 21 is the defining genetic abnormality in individuals with Down syndrome.
Therefore option A is correct.

A population of rodents lives in one species of pine tree. They have a commensalistic
relationship with the tree; they use it for protection & housing & the tree is not affected. These
pine trees have very evenly spaced branches of uniform thickness. Rodents that are too small
cannot reach between the branches to move around in the tree. Rodents that are too big and
heavy break through the branches and fall out of the trees. The rodent population that is very
uniform in size have become more populous.
9) Explain how this is related to natural selection. Make sure to include a cause and an effect
within your explanation.
a) How is this related to Natural Selection? (2 points)
b)What has caused the mice population to shift to uniform sized mice? (1 point)
c)What is the effect of this population shift?(1 POINT)
Answers
Answer: I’m not sure but it relates to natural selection because the rodents depend on the tree for survival and the tree is neither harmed or benefited from the rodents the cause and affect is the rodents stay in the tree and the tree is neither harmed or benifited.

Why can smaller cells diffuse oxygen and nutrients at a faster rate?
small surface area to volume ratio
large surface area to volume ratio
large surface area
more volume than surface area
Answers
Answer:
A further increase in the size of a cell could result in a surface area too small for adequate exchange of materials.: A large surface to volume ratio means that a small amount of living matter has a large surface through which nutrients, oxygen and wastes can diffuse.

why beta cells would have a
greater concentration of rough
endoplasmic reticulum and
ribosomes than some other cell
types.
Answers
Answer:
The intense and constant activity of insulin synthesis explains why pancreatic beta cells possess more rough endoplasmic reticulum and ribosomes than other cells.
Explanation:
Both ribosomes and the rough endoplasmic reticulum are necessary for protein synthesis to occur. In cells whose function is to produce substances, such as glands, the content of these cellular structures is higher in order to fulfill their function.
The pancreatic beta cells, located in the islets of Langerhans, have the function of synthesizing insulin, an endocrine hormone in charge of regulating the glucose content in the blood. Because the beta cells constantly produce insulin, their content of rugged endoplasmic reticulum and ribosomes is high, in order to satisfy the demand for this hormone in the body.

The diagram that explains the crossing over in the following diagram is option C, as here the crossing over takes place and the chromosomes exchange their genetic materials and can later produce the gametes.
What exactly is the significance of the cross-over in meiosis?Crossing over is important in meiosis because it occurs when homologous chromosomes exchange genetic material, resulting in the formation of new combinations of genetic information and increasing genetic diversity in the population. As a result, evolution occurs, and unique offspring are produced.
Hence, the diagram that explains the crossing over in the following diagram is option C, as here the crossing over takes place and the chromosomes exchange their genetic materials and can later produce the gametes.
