Or there might be any other environmental or genetic factor influencing the change.

All organisms, including plants, undergo what essential process?

A. Photosynthesis

B. Cellular Respiration.

C. Sexual reproduction.

All the living organisms undergo cellular respiration.

Option B

Cellular respiration is the process of production of energy from food. This process includes different chemical reactions which squeeze out energy from the food and store that in form of Adenosine Tri Phosphate for the cells to use in future. Thus without cellular respiration, a cell can't survive.

Now the photosynthesis is only restricted within a group of autotrophs which contains chlorophyll and can use Sun's energy to produce glucose from carbon dioxide and water.

Sexual reproduction is also not a feature of many lower organisms like bacteria which divide by means of binary fusion.

x= 0, y = 2

Explanation:

4x + 5y +2 = 12

Let's suppose that

x = 0

y = 2

By putting the values of x and y

4(0) + 5( 2) + 2  = 12

0 + 10 + 2 = 12

12 = 12

Hence, it is proved that x = 0 and y = 2

Answer:

Viperfish hunt by attracting prey to their glowing bellies. This adaptation is most useful for the open-ocean ecosystem.

Explanation:

In the open ocean ecosystem, not much diversity of organisms is present. In order to survive in the open ocean, an organism must have certain adaptations which will allow it to get the basic resources needed for survival. If adaptations are not provided, organisms will nor be able to survive in the open ocean ecosystem.

The adaptation of glowing bellies in the viperfish allows it to attract its preys due to which it is able to get food and survive in the open ocean ecosystem.

Its a sex linked disorder and it makes stopping the bleeding slower in affected individuals.

Hemophilia is a sex linked recessive disorder which occurs due to a gene present in the X chromosome. The presence of this gene in males surely make the individual hemophilic because the Y chromosome doesn't contain any dominant factor of this gene. In females, the recessive individuals become carriers without expression of this gene. Only the dominant individuals in females expresses Hemophilia.

Its a disease where the Christmas factor (Factor IX) or the antihemophilic factor(Factor VIII) is absent in the affected individual. This makes the cascade theory incomplete and there's a defect in blood clotting in both the intrinsic and extrinsic pathways. Thus the persons if starts bleeding, loses a lot of blood before coming to a stability.

Answer:C.) It is an example of a sex-linked disorder.  E.) It is a disease in which a person has trouble stopping bleeding.

A keloid is an excessive, abnormally large scar caused by an overproduction of collagen that exceeds the original wound and may continue to grow even after it has healed.

The excessive, abnormally large scar referred to in the question is known as a keloid. Unlike a callus, corn, or cicatrix, which are all common types of scar formations, a keloid forms when the healing process in the skin extends beyond the original wound, resulting in a large raised scar. This is due to an overproduction of collagen, creating a smooth, hard growth. It is important to note that keloids may continue to grow long after the wound has healed.

Some plants that grow on forest floors where there isn't much light have bigger ecological advantages.

Explanation:

Some of the plants that grow on the forest floor do not get ample amount of sunlight. Sunlight is required for the process of photosynthesis. These plants are less in number a lot of purposes. They become food for the herbivorous animals push up they also supply cheap form of wood for construction purposes. They also provide the support system for epiphytes and other climbers.

The cactus and brittle bush get their energy from sunlight because they are plants and use photosynthesis to make their own food.

Final answer:

Plants, algae, and some bacteria are the producers in the food web that receive their energy directly from sunlight.

Explanation:

Producers in a food web are organisms that conduct photosynthesis or synthesize sugars through other means, such as plants, algae, and some bacteria. These organisms obtain their energy directly from sunlight and convert it into usable chemical energy. Consumers, on the other hand, rely on producers, either directly or indirectly, for their energy. They include animals, fungi, and various microorganisms. For example, a deer receives its energy by eating plants, which in turn obtained their energy from sunlight. Therefore, the producers in the food web that receive their energy directly from sunlight are the plants, algae, and some bacteria.

It's a way of protecting the trees, and making sure they survive the winter and beyond. Leaves die during the winter months. If those dead leaves stayed on the trees, and new ones wouldn't grow in their place, the tree would have no way of making food for themselves.

Hope it helps. ☺

Leaves fall off trees in the fall due to cooling temperatures triggering deciduous trees to go into a dormant state, conserving water and energy. This process is called senescence. The components within the fallen leaves get recycled by the tree, providing it with nutrients during winter.

Leaves fall off trees in the fall due to a process known as senescence. This is a stage in a plant's life cycle when certain parts, such as the leaves of many trees, age and die off. This process is due to several factors, including changes in environmental conditions and photosynthetic efficiency.

Most leaves are the main sites for photosynthesis – the process by which plants produce food. When temperatures start to drop in the fall, the trees prepare for winter. They lose their leaves to conserve water and energy. The onset of cold weather causes leaf drop in a phenomenon known as deciduous trees going dormant.

A waxy cuticle on the outer surface of leaves prevents water loss, and the regulation of water is achieved by opening and closing of stomata - small openings on the leaf surface. However, to conserve water during winter, the trees drop their leaves. The elements within the fallen leaves are then recycled by the tree, feeding it during the colder months.

Answer: most likely D

Explanation:

A was close, B not it and C is only for heat use

Wind and moving water provide mechanical energy. They are renewable energy sources that harness the kinetic energy of natural movements to generate electricity. The correct answer is option (B).

Wind and moving water provide a form of energy known as mechanical energy. This type of energy is harnessed through the movement of turbines which convert the kinetic energy of wind or flowing water into electrical energy. Both forms of energy, wind power and hydroelectric power (hydroenergy), are considered renewable energy sources.

Winds and moving water are driven by the energy from the sun, which heats the Earth unevenly, causing wind, and evaporates water to high elevations, where it can later fall and flow due to gravity, powering turbines as it moves. This mechanism is similar across different forms of energy generation, such as fossil fuels, biofuels, nuclear energy, and solar thermal systems, where a spinning turbine creates an electric current.

Thus, the correct answer to the student's question is option B) mechanical energy.

Teoría cinética molecular. Las leyes de los gases desarrolladas por Boyle, Charles y Gay-Lussac, que establecieron las principales relaciones entre la presión, el volumen y la temperatura de un gas, están basadas en observaciones empíricas y describen el comportamiento de los gases en términos macroscópicos.

The statement which best describes the Kinetic Theory Model is that When particles in matter gain or lose energy, they change state. Thus, the correct option for this question is C.

The kinetic theory model may be defined as a type of theory that significantly states that all matter is composed of particles in motion and that the rate of motion varies directly with the temperature. As the temperature rises, the movement of particles gradually increases.

According to this theory model, the molecular composition of the gas is in terms of a large number of submicroscopic particles which include atoms and molecules. Further, the theory explains that gas pressure arises due to particles colliding with each other and the walls of the container.

Therefore, when particles in matter gain or lose energy, they would definitely change state with respect to the energy that is administered to them. Thus, the correct option for this question is C.
