Which statement about an individual that is homozygous for an allele is not true?

Two cities are separated by 200 miles. City X has an altitude of 122 meters and City Y has an altitude of 260 meters. Calculate

OleMash [197]

Answer: 0.69 m/ mile.

Explanation:

The altitude gradient between two cities X and Y = $\dfrac{\text{Altitude of City Y - Altitude of city X}}{\text{Distance between two cities}}\times100\%$

Given: Two cities are separated by 200 miles.

City X has an altitude of 122 meters.

City Y has an altitude of 260 meters.

The altitude gradient between two cities X and Y =

$\dfrac{260-122}{200}=0.69\text{m/ mile}$

Hence, the altitude gradient between the two cites = 0.69 m/ mile.

TRUE OR FALSE Oxygen is absorbed into the bloodstream in the trachea?

Arte-miy333 [17]

False. Oxygen is absorbed in the alveoli sacs of the lungs.

Upon inhalation Air must first pass through the larynx and down to the trachea, which then splits off into two separate bronchial tubes, the bronchial tubes divide into smaller air passages known as the bronchi and those into even smaller bronchioles. The bronchioles end in tiny sacs called the alveoli which transfer the oxygen from the inhaled air to the bloodstream.

The genes that masks the effects of other genes

kicyunya [14]

epistatic gene

Explanation:

Some genes mask the expression of other genes just as a fully dominant allele masks the expression of its recessive counterpart. A gene that masks the phenotypic effect of another gene is called an epistatic gene; the gene it subordinates is the hypostatic gene.

The highlighted structure separates the oocyte from the externally located ________. zona pellucida primary follicle corona radi

Naya [18.7K]

Answer:

Granulosa cells

Explanation:

Foliculogenesis is a dynamic and complex process through which the follicle goes through many stages of development in a short period (approximately 60 days in humans and some chimpanzees).

The stages classification is based on morphological changes such as follicular size or diameter, the number of follicular cell layers, etcetera. These classifications might vary among authors but could be denominated as:

Primordial follicle

Primary follicle

Secondary follicle and

De Graaf follicles (This is the one shown in the image)

Through each stage, there are certain modifications in the oocyte, follicular cells, and connective tissue. As the oocyte grows, the follicular cells might reach a size twice or three times bigger than the ones of the primordial follicles. Their shape also changes and they adopt an aspect of stratified epithelium. Their cytoplasm gets a granulous aspect, after what these cells receive the name of granulous cells. The De Graaf follicle characterizes for having a space named follicular antro that displaces the oocyte to one of the sides.

The oocyte at this point gets surrounded by zona pellucida and corona radiata .

The follicular antro (The highlighted structure) separates the oocyte from the externally located granulosa cells or follicular cells.
