The swallowing phase where the velopharynx closes forcefully and larynx completely closes at 3 levels is the...
a. Tongue preparatory phase
b. Pharyngeal transport phase
c. Oral transport phase
d. Laryngeal transport phase
Answer:
b. Pharyngeal transport phase
Explanation:
During the pharyngeal phase, the vocal folds close to keep food and liquids from entering the airway.
Swallowing the velopharynx closes forcefully and the larynx completely close at the level of the pharyngeal transport phase this action seal the airway passage, hence option b is correct.
What is swallowing ?According to where the bolus is located, the swallowing process is often split into oral, pharyngeal, and esophageal phases. When consuming solid food vs drinking liquid, the food moves differently through the oral cavity and into the oropharynx.
The tongue closes the oropharynx while it is in the pharyngeal phase. The proximal pharyngeal wall and soft palate serve as a barrier to the nasopharynx.
The laryngeal entrance is sealed off by the vocal cords and arytenoids, and the epiglottis swings down to cover the laryngeal vestibule. These acts close up the pharyngeal cavity's airway.
Therefore at 3 levels, the velopharynx closes forcefully and the larynx completely closes in the pharyngeal transport phase action to seal the airway passage, hence option b is correct.

Humans deplete the most resources when
Answer:
Resource depletion is the consumption of a resource faster than it can be replenished. Natural resources are commonly divided between renewable resources and non-renewable resources (see also mineral resource classification). Use of either of these forms of resources beyond their rate of replacement is considered to be resource depletion. The value of a resource is a direct result of its availability in nature and the cost of extracting the resource, the more a resource is depleted the more the value of the resource increases. There are several types of resource depletion, the most known being: Aquifer depletion, deforestation, mining for fossil fuels and minerals, pollution or contamination of resources, slash-and-burn agricultural practices, Soil erosion, and overconsumption, excessive or unnecessary use of resources.
Resource depletion is most commonly used in reference to farming, fishing, mining, water usage, and consumption of fossil fuels. Depletion of wildlife populations is called defaunation.

Which is not a unique property of water
Answer:
A
Explanation:
All of the other options are specific to water, but quite a few liquids cool off a lot faster than water.
water cools very rapidly is not a unique property of water. Thus option A is correct.
what are the properties of water molecule ?It has no taste, odor, or transparency, where the nucleus of the oxygen atom attracts electrons strongly than the nuclei of the hydrogen atoms.
In water molecule oxygen is more electro negative and electron-greedy than hydrogen, results in the development of a partial negative charge on the oxygen of the water and a partial positive charge on the hydrogen end.
Water shows strong cohesive property where the attraction of molecules for other molecules of the same kind is referred to as cohesion.
Surface tension is defined as the tendency of the surface to resist rupture when they are subjected to stress due to cohesive forces.

Your risk is greatly raised if any of these relatives have had breast or ovarian cancer. However, until many of these “secondary” relatives have the disease.
What is role of inheritance in breast cancer?A woman's risk of breast cancer nearly doubles if she has a first-degree family (mother, sister, or daughter) who has the disease.
Her risk is nearly three times higher if she has two first-degree relatives. A woman's risk of developing breast cancer is considerably higher if her father or sibling had the disease.
Gene changes that are connected to breast cancer are typically acquired. Only the breast cancer cells experience acquired DNA alterations over time.
Therefore, Hereditary is Breast cancer and Inheritance is Getting Breast Cancer, basically it runs in the family inheriting.

describe how and where carbondioxide enters the leafe?
Answer:Carbon dioxide cannot pass through the protective waxy layer covering the leaf (cuticle), but it can enter the leaf through an opening (the stoma; plural = stomata; Greek for hole) flanked by two guard cells. Likewise, oxygen produced during photosynthesis can only pass out of the leaf through the opened stomata.
Explanation:
Why do planets close to the sun have thin atmospheres and the planets far away from the sun have thick atmospheres. Use what you know about the nebular theory.
Answer:
There are two primary factors: size and distance from the Sun. Gravity helps planets and moons to hold on to their atmospheres, so small planets/moons such as Mars and the Moon have thin atmospheres. The reason why the outer planets are larger is probably down to two major factors. The first is simply the amount of material available which may be accreted to a planet. Clearly, the further away from the Sun, the longer the orbit (twice as far means an orbit twice the physical length).

Consider the separate stages of an animal virus life cycle. Assemble a list of structures and processes that are unique to the virus and would make good drug targets for an antiviral agent. Explain your rationale for each choice.
Answer:
Explanation:
In order to make an antiviral agent, we need to find good drug targets, that is, to find structures and processes that are only present in the virus, so there is no harm on human cells when this antiviral agent is being applied.
In the virion of a naked virus, only nucleic acid and protein are present forming the nucleocapsid. The nucleic acid and proteins of the capsid, specially, are found only in the virus and therefore make good drug targets. For example, we can express antibodies to recognize the proteins of the capsid and guide the immune system to destroy them.
Although virus particles are metabolically inert, one or more key enzymes are present within the virion in some viruses, for example, the reverse transcriptase. This enzyme is only found in viruses and if we find a way to inhibit the activity of this reverse transcriptase, like for example finding a competitor substrate, the virus will not be able to synthesize the DNA needed for its replication.
Regarding processes in the virus life cycle, they all have similar steps: first the attachment of the viral particle onto the cell, then the penetration of the virus, then the synthesis of early and intermediate enzymes using the host cell machinery, and finally the assembly of these viral components and lysis of the host cell to release new viral particles.
The attachment of a virion to a host cell is a highly specific process. Recognition proteins on the virus recognize specific receptors on the host cell. Substances that compete with the virion for these specific receptors can be used. If there is no attachment, there is no infection.

A cell has chloroplasts, numerous ribosomes, an endoplasmic reticulum, and a cell wall. What type of cell is this?
Answer:
The cell with chloroplasts, abundant ribosomes, plus an endoplasmic reticulum, and a cell wall is of the plant cell type.
Explanation:
Plant cells are eukaryotic cells found in all plants, with specific characteristics given their ability to be autotrophic and use solar energy to synthesize their nutrients. The presence of many ribosomes and a developed endoplasmic reticulum is due to their high capacity for plant protein synthesis.
One characteristic that differentiates plant and animal cells is the presence of a cell wall, which surrounds the cell membrane, and chloroplasts. Chloroplasts are responsible for making the process of photosynthesis possible.
