Answer:
The correct answer will be option-The red and white flower alleles are co dominant.
Explanation:
The Mendel suggested that for any trait, the organism contains its alleles which could be dominant and recessive. But there are cases in which multiple alleles exist for the same trait which are neither dominant nor recessive.
Two cases arise due to this in which both the dominant alleles co-exist and show their phenotype effect called "co-dominance" and when both alleles form a new phenotype called 'incomplete dominance".
In the given case, the self-pollination produces red, white and patched flowers as a result of co-dominance because both the alleles show the equal effect on the flower petals (mixed phenotype) and form a flower with red patches or spots on the flower.
Thus, the selected option is the correct answer.
Answer:
Fundus.
Explanation:
The fundus or ophthalmoscopy consists of viewing the retina and the optic disc through the pupil and the transparent media of the eyeball (cornea, aqueous humor, crystalline humor, and vitreous humor) including the optic disc, retinal vessels, macular area and fundus as a whole. It is an important component of the clinical evaluation of many diseases and is the only location where the vascular bed can be observed in vivo in a bloodless manner. The direct ophthalmoscope is available to perform it in Primary Care (PC) consultations and in other specialties, this is an optical instrument that directs light directly onto the retina through a mirror that reflects a ray from the light source. This mirror has a central hole that allows the observer to view the illuminated retina. The major retinal vessels are examined and tracked distally as far as possible in each of the four quadrants (superior, inferior, temporal, and nasal). The color, tortuosity, and caliber of the vessels are examined. The posterior pole is between the temporal vascular arches, measures 5-6 mm, and is where most of the lesions in diabetic retinopathy are located, such as microaneurysms, hemorrhages or exudates.
Answer:
Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries. Volcanoes are one kind of feature that forms along convergent plate boundaries, where two tectonic plates collide and one moves beneath the other.
Explanation:
Volcanoes at convergent plate boundaries are found all along the Pacific Ocean basin, primarily at the edges of the Pacific, Cocos, and Nazca plates. Trenches mark subduction zones. The Cascades are a chain of volcanoes at a convergent boundary where an oceanic plate is subducting beneath a continental plate.

Let us consider a drop of water in a river. The droplet flows to a larger body of water such as a lake. From here, or even from the river, the droplet changes from the liquid to the vapor phase via the process of evaporation and goes into the atmosphere. In the atmosphere, the droplet is condensed back into the liquid phase in the form of cloud. When a sufficient amount of water has been created in the clouds, it precipitates back on to the ground and flows into rivers and streams again.<span />
