Respiratory epithelium is ciliated pseudostratified columnar epithelium found lining most of the respiratory tract; it is not present in the larynx or pharynx

Respiratory epithelium, also known as airway epithelium, is a form of ciliated columnar epithelium that lines the majority of the respiratory tract called respiratory mucosa and acts to moisten and protect the airways.

It is not seen in the laryngeal vocal cords, or the oropharynx and laryngopharynx, where the epithelium is stratified squamous. It also acts as a barrier to possible pathogens and foreign particles, preventing infection and tissue damage by mucus secretion and mucociliary clearance.

Yes, because In 1997, El Niño had not spread as far across the equator in comparison to 2015. During an El Niño event, warm ocean waters accumulate in the central and eastern tropical Pacific, disrupting the normal atmospheric circulation patterns.

El Niño refers to a climatic occurrence marked by the increase in temperatures of the ocean's surface in the central and east areas of the tropical Pacific Ocean.  It has the potential to cause considerable changes in global weather phenomena.

The intensity and scope of El Niño occurrences differ annually. The year 2015 experienced a robust El Niño, which had significant and far-reaching impacts on weather systems around the world.

Answer: the digestive system is capable enough to absorb the nutrients out of food that we eat, which is the same with the other body parts in our body when we take in food.

Answer:

The statement means that the human digestive system can adapt to extreme diets in order to survive. For example, carbohydrates can be broken down into sugars and used for energy. But when carbohydrates are not available in the required amount, it can also break down fats to provide the body with the required amount of energy. This explains why Deb has enough energy to keep going, even on her extremely limited diet.

Explanation:

The salivary glands, stomach, and pancreas secrete lipase enzymes to break down triglycerides into monoglycerides, fatty acids, and glycerol.

Lipases are a set of water-soluble enzymes that hydrolyze substrates such as triglycerides and phospholipids, have a similar structure and are essential in the metabolism of lipoproteins and lipids.

That is, the function of lipase enzymes is to hydrolyze triglycerides to generate diglycerides, monoglycerides, fatty acids and glycerol.

About lipase enzymes:

Therefore, we can conclude that the salivary glands, stomach, and pancreas secrete lipase enzymes to break down triglycerides into monoglycerides, fatty acids, and glycerol.

These differences reflect different mechanisms of cell entry and different pathways of assembly and maturation. Enveloped viruses enter by membrane fusion, either from an internal compartment following an endocytic step, or at the cell surface. Non-enveloped viruses require some form of membrane “perforation”.

True, below the lithosphere, terrestrial planet mantle is the layer of interior that lies beneath the crust and outer core.

Above the lithosphere, terrestrial planet mantles are primarily melted rock (magma) is because there aren't many SiO2 molecules that could be converted into glass by heat and pressure at great depths in the mantle—only CaO molecules can do so under these conditions (and they don't do it very well)..

The mantle has a thick upper mantle and a thin lower mantle. The upper mantle is where most of the crust forms, because it contains relatively large amounts of silica from which the crust can grow. The lower mantle has a much higher proportion of iron and magnesium than the upper mantle does, and it also contains small quantities of silicon-30 (SiO2) and calcium-40 (CaO).

Many people live much longer than 5 years after their cancer diagnosis. The term does not mean a person will only survive for 5 years.

For example, 90% of people with breast cancer will be alive 5 years after the diagnosis of cancer.

Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.

Cancer is a disease caused when cells divide uncontrollably and spread into surrounding tissues.

Answer:

True

Explanation:

Answer:

Variations in species led to evolution. Some species have desirable traits that are beneficial to their survival. Some species have undesirable traits that are not beneficial to their survival. E.g. peppered moths are not easily seen by predators because they camouflage with the bark, black moths are easily seen by predators so they are eaten. In the example mentioned, the peppered moths have a beneficial trait, this is also known as fitness, because the organism is fit for survival, unlike the black moths. Overtime the population of black moths decreases because they are not fit for survival, therefore the black moths cannot reproduce offspring that also have black wings. However, the population of peppered moths increases, because the peppered moths are able to reproduce offspring. Those offspring inherit their parents' traits, which make them have peppered wings too.

Hi! I'm happy to help you with your question. Based on the provided information, we can identify the general and specific speciation mechanisms.

General speciation mechanism: Allopatric speciation

Specific speciation mechanism (which type of your answer to part #1 is observable in this case): Vicariance

Your answer:
In this case, the general speciation mechanism is allopatric speciation, which occurs when populations of a species become geographically separated and, over time, evolve into distinct species. The seeds being transported from the original island by migratory animals would lead to geographical separation, providing the opportunity for allopatric speciation to occur.

The specific speciation mechanism observable in this case is vicariance, a type of allopatric speciation. Vicariance occurs when a geographical barrier (in this case, the distance between the original island and the new location) prevents gene flow between populations, leading to genetic divergence and the formation of new species.

Allopatric speciation involves the separation of an original population into different isolated groups separated by ecological or geographical barriers. 1- Allopatry. 2- Vicariance.

Allopatric speciation is the type of speciation process that involves the geographic separation of a continuous genetic background so that it can give place to two or more new geographically isolated populations.

These separations might be due to migration, extinction of geographically intermediate populations, or geological events.

In this speciation, some barriers impede genetic interchange, or genetic flow, as the two new populations that are separated can not get together and mate anymore. These barriers might be geographical or ecological.

Whenever a geographical barrier emerges and separates an original population into two or more groups, we can talk about vicariance. There is a discontinuity in the environment that divides a population that originally was continuous.

Your answer is C). If the plant is releasing water into the air, that must mean that there is an excess of water in the plant, and photosynthesis can only occur when sunlight is present.

This process is called "Dissociation"

The cell structure that defines the outer boundary of all cells, separating the cell's contents from its environment is the cell membrane.

The cell membrane, also known as the plasma membrane, is a thin, flexible barrier that surrounds the cell and controls the movement of substances in and out of the cell. It is composed of a phospholipid bilayer, which consists of two layers of phospholipids. The phospholipids have a hydrophilic (water-loving) head and a hydrophobic (water-repelling) tail. This arrangement allows the cell membrane to selectively allow certain substances to enter or exit the cell.

In addition to phospholipids, the cell membrane also contains proteins, cholesterol, and carbohydrates. Proteins embedded in the cell membrane help transport molecules across the membrane, provide structural support, and facilitate cell communication. Cholesterol helps maintain the fluidity and stability of the cell membrane. Carbohydrates attached to proteins and lipids on the outer surface of the cell membrane play a role in cell recognition and cell-cell interactions.

Overall, the cell membrane acts as a barrier that separates the internal environment of the cell from the external environment, allowing the cell to maintain homeostasis and control its interactions with the surrounding environment.

Answer:

Energy transfer is the movement of energy from one location to another. For example, when electricity moves from a wall plug, through a charger, to a battery.

Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy.

While energy can be transferred or transformed, the total amount of energy does not change ­– this is called energy conservation.

Why is soil important?  Soil is our life support system. Soils provide anchorage for roots, hold water and nutrients. Soils are home to myriad micro-organisms that fix nitrogen and decompose organic matter, and armies of microscopic animals as well as earthworms and termites.

What is soil erosion?  Soil erosion is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water (Figure 1) and wind (Figure 2) or through forces associated with farming activities such as tillage.

what human activities are responsible for soil erosion happening at advance rates?     Ploughing, unsuitable agricultural practices, combined with deforestation and overgrazing, are the main causes of human-induced soil erosion

What are some effects on soil loss?  The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.

What can be done to prevent soil erosion?   Maintaining a healthy, perennial plant cover.

Mulching.

Planting a cover crop – such as winter rye in vegetable gardens. ...

Placing crushed stone, wood chips, and other similar materials in heavily used areas where vegetation is hard to establish and maintain.
