D.) carbon dioxide

Answer:

wind erosion

- i know this question is older but i hope this helps anyone who may need it. :-)

The geologic process that creates an alcove is wind erosion, which is present in Option B, as the alcove is a recessed area in a rock or cliff face that is often semicircular in shape.

Alcove is created by the process of wind erosion. Over time, wind can carry abrasive particles, such as sand or small rocks, that erode the softer rock on the face of a cliff, carving out a hollow space. As the wind continues to erode the rock, the hollow can deepen and expand, forming an alcove. Alcoves are often found in areas with strong, consistent winds, such as desert regions, and can range in size from small niches to large, room-sized spaces. In addition to wind erosion, alcoves can also be created by other geologic processes such as water erosion or tectonic activity.

Hence, the geologic process that creates an alcove is wind erosion, which is present in Option B.

Explanation:

Protozoa have been classified into three trophic categories: the photoautotrophs which harness the sun's radiant energy in the process of photosynthesis; the photoheterotrophs, which although phototrophic in energy requirements, are unable to use carbon dioxide for cell synthesis and must have organic carbon compounds

Protozoa in the soil food chain does not obtain energy directly from plants. So, the correct option is C.

Protozoa is defined as a group of single-celled eukaryotes, which is either free-living or parasitic, that feed on other microorganisms or on organic matter such as organic tissues and debris.

One advantage is that secual reproduction provide variation which can help living things survive in different environment. Asexuals cannot have variation.

Explanation:

One advantage is that sexual reproduction provide variation which can help living things survive in different environment. Asexuals cannot have variation.

When sperm from a male parent fertilizes an egg from a female parent during sexual reproduction, the result is an offspring that is genetically distinct from both parents.

The genetic diversity of organisms is a result of sexual reproduction. Meiosis, a process that creates sperm and egg cells, is the first step in sexual reproduction.

Because they have half as many chromosomes as the parent, these cells are known as haploids. A diploid zygote is created during sexual reproduction when a male parent's haploid sperm fertilizes a female parent's haploid egg.

Therefore, One advantage is that sexual reproduction provide variation which can help living things survive in different environment. Asexuals cannot have variation.

Answer:

Examples of Newton's third law of motion are ubiquitous in everyday life. For example, when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air. Engineers apply Newton's third law when designing rockets and other projectile devices. Two other examples are: As a professor paces in front of a whiteboard, he exerts a force backward on the floor. A car accelerates forward because the ground pushes forward on the drive wheels, in reaction to the drive wheels pushing backward on the ground.

The principal RNA involved in protein synthesis is tRNA rather than the mRNA that is produced during transcription, which is carried from the nucleus into the cytoplasm to the ribosome. Thus, option C is correct.

A DNA strand serves as a template for the construction of the RNA molecule during transcription. The protein synthesis process and DNA are connected by the RNA molecule.

The RNA molecule produced during transcription transmits data from the DNA to the machinery that makes proteins during translation.

Because they control the creation of proteins, nucleic acids—the primary information-carrying molecules of the cell—determine the inherited traits of every living creature.

Deoxyribonucleic acid (DNA) and ribonucleic acid are the two primary types of nucleic acids (RNA).

Therefore, carries amino acids that are bonded together to form proteins is not a function of nucleic acids.

Explanation:

the answer is A..........

An organism most likely would respond to an extremely cold temperature as the blood vessels would constrict to reduce the heat loss through the negative feedback. Thus, the correct option is A.

Adaptations are the changes in the body of a living organism which help them to survive better in a particular set of environmental condition such as hot temperature, cold temperature, etc.

In cold temperature, Shivering is an adaptation in which the nerve impulses are sent by the hypothalamus of the brain to the skeletal muscles to bring about rapid contractions which generate heat and this helps the body in staying warm. Shivering therefore helps an organism in raising the body temperature. Increase in the metabolic rate, the liver produces extra amount of heat in order to raise the temperature of the body.

Cell theory is a scientific theory that's help to learn how living organisms are made up of cells, that's they are the basic structure unit of all organisms, and that all cells from pre-existing cells.

Prokaryotic cells are single-celled microorganisms known to be  earliest on earth.Eukaroyotic cell have a nucleus enclosed within the nuclear membrane and form large and complex organism.

Difference between unicellular and multicellular.

The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialised it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.

Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.

In unicellular organism division of labour is at the organ level on the other hand in multicellular the division of labour at cellular, tissue, organs and organ system level. Unicellular organism has simple body organization and multicellular organism have complex body organism.

Answer: The theory states that the earth's crust is divided into massive slabs known as tectonic plates.

Explanation:

These plates move on the mantle which is a layer made of magma, which consists of semisolid rocks.The heat from earth's core causes convection currents much like in a beaker full of water.But, here the force developed by the magma is so great that it slowly moves the plates like boats on sea over millions of years.

Answer:

Plants use carbon and release oxygen, and animals release carbon and use oxygen.

Explanation:

The statement that accurately describes the relationship between plants, animals, and the carbon cycle is:

Plants use carbon and release oxygen, and animals release carbon and use oxygen.

Plants play a crucial role in the carbon cycle through the process of photosynthesis. They absorb carbon dioxide (CO2) from the atmosphere and use it, along with sunlight and water, to produce carbohydrates and release oxygen as a byproduct. This process helps to remove carbon from the atmosphere and convert it into organic compounds.

On the other hand, animals (including humans) obtain energy by consuming plants or other animals. During respiration, animals take in oxygen and release carbon dioxide as a waste product. This carbon dioxide is then released back into the atmosphere, where it can be used by plants for photosynthesis.

Therefore, plants contribute to the reduction of atmospheric carbon dioxide levels by using carbon during photosynthesis and releasing oxygen, while animals contribute to the carbon cycle by releasing carbon dioxide during respiration and utilizing oxygen.

Answer:

The sun's thermal energy causes water on the earth to evaporate. The water vapor then condenses and forms precipitation. The precipitation then falls back to the surface of the earth.

Explanation:

The water cycle is an illustration of how water continuously moves or circulates between the atmosphere and the various parts of the earth.

Evaporation of water from the surface of the earth by the thermal energy from the sun causes water to leave the surface of the earth into the atmosphere. When the atmospheric water vapor (humidity) at the upper strata of the atmosphere becomes high, the vapor condenses to form clouds which later forms precipitation that falls back to the surface of the earth.

The ocean's tidal energy does not cause water to cycle on earth.

the movements of rivers, tectonic activity, and erosion.
