D.    Is the correct answer

Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Strands of hair originate in an epidermal penetration of the dermis called the hair follicle. The hair shaft is the part of the hair not anchored to the follicle, and much of this is exposed at the skin’s surface. The rest of the hair, which is anchored in the follicle, lies below the surface of the skin and is referred to as the hair root. The hair root ends deep in the dermis at the hair bulb, and includes a layer of mitotically active basal cells called the hair matrix. The hair bulb surrounds the hair papilla, which is made of connective tissue and contains blood capillaries and nerve endings from the dermis.

The part of the hair that extends from the hair bulb to the hair shaft is the hair root, which is the only living part of the hair, and the hair shaft is the visible dead part comprised of dead keratinocytes.

The part of the hair that extends from the hair bulb to the hair shaft is known as the hair root. The hair root is located within the hair follicle and is the only living part of the hair. The hair shaft, in contrast, is the portion of the hair that becomes visible above the skin's surface and consists of dead keratinocytes.

As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface, where it is visible as the part of the hair we see and style. The hair shaft comprises three layers: the cuticle, the cortex, and the medulla. This growth process and the layered structure contribute to the unique features of hair, such as its texture and the fact that it can be cut without sensation or damage to the structure.

The activation energy as per the definition given by Svante Arrhenius is the minimum amount of energy that is needed for the chemical reaction to proceed. If the amount of the activation energy is decreased then, the reaction would be completed faster.

Explanation:

A catalyst is defined as the substance that lowers the activation energy of a chemical reaction without itself getting consumed so that there will be increase in rate of reaction.

As catalyst lowers the activation energy so, reactant molecules with lower energy also participates in the reaction. Hence, more collisions occur due to which there is rapid formation of products.

Thus, we can conclude that if the activation energy required for a chemical reaction were reduced then there will occur an increase in the rate of the reaction.

Answer:

Outermost shell

Explanation:

in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell.

Both aerobic and anaerobic respiration involve chemical reactions which take place in the cell to produce energy, which is needed for active processes. Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy.

The key difference between aerobic and anaerobic respiration lies in the requirement and usage of oxygen, and the amount of ATP they produce. Aerobic respiration requires oxygen, happens in mitochondria, and generates more ATP. Contrarily, anaerobic respiration does not need oxygen and yields less ATP.

The primary difference between aerobic respiration and anaerobic respiration lies in their requirements and products of glucose metabolism. Aerobic respiration, which is the breakdown of glucose in the presence of oxygen, results in the production of carbon dioxide, water, and energy in the form of ATP. It takes place in the mitochondria and can generate approximately 36 ATP per molecule of glucose, thus serving as a primary source of energy for resting or moderately active muscles.

On the contrary, anaerobic respiration occurs in the absence of oxygen, converting glucose into two lactate molecules or through a process called fermentation. This respiration is less efficient, producing fewer ATP per glucose molecule. However, it can provide energy when oxygen is scarce.

So to recap, aerobic respiration requires oxygen and generates more ATP, while anaerobic respiration does not demand oxygen and provides less ATP.

The correct answer is: B. The water before filtration is a mixture because the particles could be physically separated.

A mixture is composed of more than one individual substances that can be separated using different methods (depending on the type of mixture). Methods  for the separation include filtration, evaporation, distillation and chromatography. The dirt stays behind in the filter paper (it becomes the residue) andthe water passes through the filter paper (it becomes the filtrate).

B. Both granite and basalt are fine-grained intrusive igneous rocks.

Intrusive igneous rocks crystallize below Earth's surface, and the slow cooling that occurs there allows large crystals to form.

Answer:

Option (A)

Explanation:

Granite is an igneous rock in which the crystals are large enough to be seen with the naked eye and it is an intrusive type of rock. They are felsic in nature as they contain a high amount of silica. They are light-colored and are formed in the continental crust. This rock is formed when hot intruding magma gets crystallized under the earth's surface. They have a relatively low specific gravity.

Basalt is also an igneous rock in which the crystals are small enough to be observed and is an extrusive rock. They are mafic in nature due to their lesser amount of silica content. They are dark-colored and are commonly associated with the oceanic as well as continental crust. This rock is formed on the ocean floor and has a high specific gravity.

Thus, the correct answer is option (A).

Mechanical weathering is the breaking of rocks on Earth's surface. These are somethings that contribute to it:

- Temperature shocks: when rocks are cold and are exposed to hot temperatures or vice versa, these can cause them to fracture.

- Earthquakes: the movements of the Earth's surface will most likely generate big cracks on superficial rocks.

- Humans: human activity can also fracture the rocks on our surface.

The nucleoid in a prokaryotic cell is where the cell's genetic material (usually a single circular DNA molecule) is located and organized, serving as the primary genetic control center for the cell's functions.

The nucleoid in a prokaryotic cell serves as the region where the genetic material, typically a single circular DNA molecule, is located and organized.

It functions as the cell's primary genetic control center, containing the genetic instructions necessary for the cell's growth, reproduction, and various metabolic activities. Unlike eukaryotic cells, which have a well-defined nucleus, prokaryotic cells lack a true nucleus, and their genetic material is found within the nucleoid, which is not membrane-bound.

The nucleoid in a prokaryotic cell is an irregularly shaped region that contains most of the cell's genetic material. It functions to house and organize prokaryotic DNA.

Unlike eukaryotic cells, prokaryotic cells do not have a nuclear membrane surrounding their DNA. The DNA within the nucleoid is typically circular and haploid.

In general, prokaryotic DNA in the nucleoid interacts with nucleoid-associated proteins (NAPs) which assist in the organization and packaging of the chromosome. In bacteria, these NAPs function similarly to histones in eukaryotes. The primary role of the nucleoid is to house the cell’s DNA and associated proteins, organizing them into a compact structure so that the cell can efficiently manage its genetic information.

Photosynthesis is the natural process by which plants synthesized their food with the help of sunlight and chlorophyll.

The carbon dioxide and water are the substrate and glucose and oxygen are the products to this process.

Increase in the amount of sunlight, carbon dioxide increases the rate of photosynthesis until the maximum rate of photosynthesis is achieved.

However, temperature shows the bell-shaped curve when it is placed against the photosynthesis rate. The photosynthesis rate is efficient under optimum temperature range. Beyond this range, that is, extreme temperature (whether extreme heat or cold) decreases the rate of the photosynthesis.

An individual palm tree growing in a tropical forest is classified as an epiphyte, which grows on other plants and utilizes their physical support.

Explanation:

An individual palm tree growing in a tropical forest can be classified as an epiphyte. Epiphytes are plants that grow on other plants, using them as physical support. These plants are able to grow high up in the canopy, where sunlight is more plentiful.

Furthermore, epiphytes, such as bromeliads, ferns, and orchids, live on rain and minerals collected in the branches and leaves of the supporting plant. They have specialized tissues that allow them to efficiently capture and store water.

In summary, an individual palm tree growing in a tropical forest is classified as an epiphyte, a plant that grows on other plants for support and can thrive in the canopy of the forest.
