Answer:

The correct answer will be option-nasal cavity.

Explanation:

The pharynx is the hollow tube which is divided into three parts: the nasopharynx, oropharynx, and hypopharynx.

The nasopharynx is the upper part of the throat present behind the nose which is 3 to 4 cm long and 2 to 3 cm wide. The nasopharynx connects the mouth to the nose and allows a person to inhale through the nose.

Thus, the option-nasal cavity is the correct answer.

Answer: Lacrimal glands

Explanation:

Lacrimal glands are not directly connected with the nasopharynx. Basically, it is located at the lateral end of the eye within the orbit and its function is to produced the fluid which help and protects the surface of eye because it provides moisturize. The lacrimal produced in the form of tears.

Therefore, it is not directly connected with the nasopharynx while other are connected.

The macronutrients that we consume are broken down through digestion and then absorbed in order to ultimately. True or False

EastWind [94]

The question is incomplete as it is incomplete therefore a picture of the complete question has been attached.

Answer:

To be used by the cells for energy

Explanation:

The digestive process of humans digest or breakdown or oxidise the organic molecules present in the food to simple compounds which could be easily utilised by the human body.

The human body composed of tissue and cell requires energy to perform metabolic reactions in the form of ATP which are provided by the digestion of the complex food material.

The macronutrients present in the food thus are digested and absorbed by the cells to perform reactions which could provide energy therefore the selected option is the correct answer.

How is the equal genetic contribution of male and female parents ensured in the progeny.

igomit [66]

Equal genetic contribution of male and female parents is ensured by the meiosis of the germ cells.

<h3>What is meiosis? </h3>

Meiosis is very similar to mitosis. In the process of meiosis, the cell goes through similar stages as mitosis and uses similar strategies for the organization and separation of chromosomes.

During meiosis, the task is a little bit more complex. The sister chromatids still need to separate. Sister chromatids are the two halves of a duplicated chromosome. This happens in mitosis too.

The chromosomes separated must be homologous. These are similar but nonidentical pairs of chromosomes that an organism receives from its two parents.

This goal is achieved in meiosis by a two-step division process.

In meiosis I, the homologous pairs separate during the first round of cell division.
In meiosis II, the sister chromatids separate during the second round of cell division.

Here, the cell division happens twice, one starting germ cell produces four gametes. In females, it's eggs, and in males, it's the sperm. In each round of division, cells have to undergo four phases. These are prophase, metaphase, anaphase, and telophase.

Therefore, the equal genetic contribution of male and female parents is ensured by the meiosis of the germ cells.

Hotspots are plumes of magma that originates deep below the ______. with respect to overlying plates, these plumes can remain __

rusak2 [61]

The hotspots are regions, where the plumes of magma are present just below the lithosphere. The plume of the magma is the particles of the volcano and the gases, which is erupted during the volcanic eruption. It is generated by the fragmentation of the magma. Once, it reaches the lithosphere, it get spreaded laterally.

The plumes at the hotspots are present just below the tectonic plates, a high temperature r heat and the low pressure causes the rocks present in the lithosphere to melt resulting in volcanic eruption. At hotspot, the melting of rock takes time, sometimes it is very slow, due to the presence of various tectonic plates. Hence, the plumes can remain stationary for a very long period of time without erupting.

So, the first blank can be filled with Lithosphere and the second blank can be filled with Stationary.
