Answer: Basal surface is the surface of epithelial cell lies closest to its blood supply.

There are three surfaces in the epithelial cell.

1. apical

2. lateral

3. basal

1. Apical surface :  This is the surface which faces towards the cell and it is the exposed layer.

2. Lateral surface : This is the surface which is in between the adjacent cells.  

3. Basal surface :  It is divided into two lamina : Basal and Reticulate.

Basal lamina is made up of glycoproteins and collagen, this lamina remains separated from underlying connective tissue. Basal lamina is in attachment with Reticulate lamina.  Reticulate lamina is in contact with underlying connective tissues this arrangement forms a basal membrane for linking the epithelial surface with connective tissue layer or region of blood supply.

Answer: The surface of an epithelial cell which lies closest to its blood supply is called as the Basal surface.

Epithelial cell is primarily composed of two surface-

1) Apical surface- It is exposed to the environment and lies towards the lumen or internal organ cavity.  

2) Basal/ Basolateral surface- It is not exposed to the environment. It lies interiorly and attached to the basement membrane via integrin.

Epithelial cells do not have own blood supply. For obtaining nutrients, they are dependent on the blood capillaries which are present in the nearby tissues. For accomplishing this, the basal surface of epithelial cell plays an essential role. The nutrients from blood enters basal surface via basement membrane which is a selectively permeable membrane.

Thus, basal surface of epithelial cells lies closest to the blood supply.  

Where's the evolution?

The physics of light affects not just how blue water looks to us, but how the animals living in the world's oceans, lakes, and rivers are able to find food and each other — and this, in turn, can impact their evolution. Natural selection favors traits that perform well in local environmental conditions. Many fish species, for example, have evolved vision that is specifically tuned to see well in the sort of light available where they live. But even beyond simple adaptation, the physics of light can lead to speciation. In fact, biologists recently demonstrated that the light penetrating to different depths of Africa's Lake Victoria seems to have played a role in promoting a massive evolutionary radiation. More than 500 species of often brightly colored cichlid fish have evolved there in just a few hundred thousand years!

Final answer:

Natural selection in the cichlid species of Lake Victoria occurred through rapid adaptive radiation, with species diversifying into various niches. This process led to the creation of about 500 different cichlid species, emphasizing the role of natural selection in biodiversity.

Explanation:

Natural selection in the cichlid fish species of Lake Victoria occurred via adaptive radiation, which is a rapid branching through speciation of a phylogenetic tree into many closely related species. This diversification allowed the cichlids to fill different niches and habitats, resulting in hundreds of species with specialized feeding strategies such as eating plankton, scraping algae, eating insect larvae, and eating the eggs of other cichlid species. The cichlids' remarkable diversity, which included about 500 species, showcases the power of natural selection in shaping biodiversity within a relatively short span of time, in this case, less than three million years.

Unfortunately, the introduction of the Nile perch, declining lake water quality, and increased fishing pressure contributed to the dramatic decline and extinction of many cichlid species in Lake Victoria, reducing the once vibrant biodiversity.

The answer is A: Infiltration.

A: infiltration because the rainwater is seeping into the ground.

An asteroid refers to an eosinophilic body exhibiting gradiating lines, observed in a vacuolated region of the cytoplasm of a multinucleated giant cell, mainly witnessed in sarcoidosis, however, also observed in other granulomas.  

It is also considered as a structural feature of sporotrichosis when observed in the skin or in secondary lesions of sporotrichosis. Thus, in order to be considered as a cell, it must possess a nucleus and membrane-bound organelles.  

Asteroids, such as C-type asteroids, contain components like organic carbon compounds and bound water, which are vital to life. However, to be considered a cell, it must have a cell membrane, genetic material, metabolism, and the capability to reproduce. There is no evidence yet of complete cells within asteroids.

Asteroids, especially C-type asteroids, are known to contain organic carbon compounds, silicates and chemically bound water, all of which are vital to the formation of cells. As remnants from the early solar system, asteroids may hold clues to the building blocks of life.

However, for a material to be considered a cell, it must meet several criteria. It must have a membrane that separates it from its surroundings, it must have a genetic material (DNA or RNA) for information replication, it must exhibit metabolic processes to utilize energy, and must be able to reproduce or self-replicate. Given the existing knowledge, asteroids do not contain fully formed cells, but they do hold some of the chemical precursors needed for life.

Answer: Glycolysis

The first stage of cellular respiration is glycolysis that takes place in the cytosol of the cytoplasm. Basically, in this process, the glucose splits up. The enzymes break down the glucose molecules into molecules of pyruvic acid. To split the glucose molecules energy is needed and that energy is provided by the molecules of ATP.

The kerbs cycle is the third stage of the cellular respiration. The pyruvic acid molecules that were produced in the first step i.e. glycolysis, enters the mitochondrion and starts the kerbs cycle. And the energy from the molecules is stored in 16 energy carrier molecules which includes four molecules of ATP’s as well.

Answer: the hair becomes club hair during the regression phase

Explanation:

Salad dressing is an example of a heterogeneous mixture. The reason it is heterogeneous is because not everything is perfectly mixed in together. In most salad dressings, there are chunks or particles that you can visibly see and separate. For the mixture to be considered homogeneous, everything would have to be combined smoothly, you wouldn't be able to see any chunks, and nothing would have been able to be separated, at least by physical means.

A mixture is a solution or a suspension that is made up of two or more components. Mixtures can be classified as:

This heterogeneous mixture is a suspension of oil and vinegar.

An Italian salad dressing is a mixture that is made up of components such as oil, vinegar, spices e.t.c

When oil mixes with vinegar the solution formed is called an immiscible solution. This is because oil mixing with vinegar does not form a uniform solution.

Hence, a mixture of oil and vinegar is a heterogeneous mixture.

Therefore, the correct option is Option A.

Answer:

Anaerobic process

Cellular respiration requires oxygen and a food molecule such as glucose, and it gives off carbon dioxide, water, and energy. Pathways of cellular respiration that require oxygen are said to be aerobic. Glycolysis does not require oxygen, so it can quickly supply energy to cells when oxygen is unavailable.

Why does darkness affect the light-independent reactions of photosynthesis?

Why does darkness affect the light-independent reactions of photosynthesis? Plants stop their daytime activities and rest during the night much like animals do. ... Mitochondria produce sugars more effectively in the darkness than chloroplasts do. Light independent reactions require the energy gathered in the

Darkness affects the light-independent reactions or Calvin cycle in photosynthesis indirectly by halting the production of ATP and NADPH from the light-dependent reactions, which are necessary for the Calvin cycle to synthesize carbohydrates.

Light-independent reactions, also known as the Calvin cycle, in photosynthesis, don't necessarily occur in darkness but are called 'light-independent' because they do not require light to proceed. They use the ATP and NADPH produced in the light-dependent reactions to convert carbon dioxide into carbohydrates. However, the Calvin cycle can be indirectly affected by darkness because the light-dependent reactions, which produce the ATP and NADPH needed for the Calvin cycle, cease without light. Without these products, the Calvin cycle cannot proceed efficiently. Additionally, enzymes like rubisco in the Calvin cycle are also sensitive to light and may be less active in the dark, further reducing the Calvin cycle's effectiveness at night.

Active transport requires energy and moves molecules against their concentration gradient, while passive transport does not require energy and moves molecules following their concentration gradient.

The fundamental difference between active and passive transport lies in the requirement of energy and the direction of molecular movement. Active transport requires energy, usually in the form of adenosine triphosphate (ATP), and moves molecules against their concentration gradient (low to high concentration). Examples of active transport include the sodium-potassium pump where sodium ions are pumped out of cells and potassium ions are pumped into cells, both against their concentration gradients.

On the other hand, passive transport does not require energy and moves molecules from areas of high concentration to areas of lower concentration, following their concentration gradient. Examples of passive transport include simple diffusion and facilitated diffusion.

Answer:

Protein activity rises as temperature  rises, and in turn, improves the rate of the reaction.

Explanation:

Warmth plays a vital role in biology as a way to control reactions. Protein activity rises as temperature  rises, and in turn, improves the rate of the reaction. This also means activity lowers at colder  temperatures. All proteins have a variety of temperatures when they are working, but there are some  temperatures where they work optimally. Using the latest Celsius mode of temperature measurement, we  can quickly discover how warm or cool it is. It was also known as Centigrade. This is because it is based  on the freezing and boiling points of water with 100 degrees within those temperatures. The main SI unit  of temperature is the Kelvin, which measures certain temperatures. However, for our everyday practice,  we use Celsius which is directly associated to kelvins. This is placed so that pure liquid freezes at zero  degrees Celsius and boils at one hundred degrees Celsius.

An amoeba feeds through a process called endocytosis, specifically phagocytosis. This involves engulfing food particles with its plasma membrane which forms a vesicle. The food is then broken down and absorbed, and waste is expelled through exocytosis.

The process through which an amoeba feeds is called endocytosis. This is a type of active transport that involves the movement of particles such as large molecules, parts of cells, and even whole cells, into a cell. The amoeba surrounds the food particle with its plasma membrane, which invaginates, forming a pocket around the food particle. This pocket then pinches off, resulting in the food particle being contained in a newly created intracellular vesicle formed from the plasma membrane. This is sometimes referred to as phagocytosis, a type of endocytosis. Once the food particle is fully enclosed in the vesicle, it is broken down and absorbed by the amoeba. Any waste that remains is then expelled from the amoeba through a process known as exocytosis.

Answer:

The correct answer is - Facilitated diffusion through protein channels.  

Explanation:

Glucose is a large molecule which is a 6- carbon sugar that stored energy for cellular functions. As it is a macromolecule that is difficult to move across the cell membrane by simple diffusion.

The facilitated diffusion is the process that helps large molecules to pass through the plasma membrane down the concentration gradient with the help of protein channels. As the glucose moves down the gradient by this process there is no need for energy as channels regulate the movement of molecules.

Thus, the correct answer is - Facilitated diffusion through protein channels.

Final answer:

The most sensitive part of the body is the face, especially the anterior two-thirds of the tongue. This is determined through special and general sensory tests.

Explanation:

The most sensitive part of the body is the face, especially the anterior two-thirds of the tongue. These areas are responsible for taste, which is a special sense. Testing the sensitivity of general senses like touch and painful stimuli can help determine the level of sensitivity in different parts of the body.

For example, sensitive parts like the face and fingers have more representation on the brain's cortex compared to less sensitive parts like the legs or back. This means that the brain devotes more space to process sensory information from these highly sensitive areas of the body.
