Answer:

Process of the cells, tissues, organs, and organ systems all working together to maintain a stable internal environment are best defined by the term homeostasis (option B).

Explanation:

All living organisms perform their functions properly by maintaining some conditions of the internal environment constant, such as temperature, pH and amount of water or electrolytes. This also guarantees a healthy state and a longer life.

The maintenance of the organic balance is done by an internal regulation system, called homeostasis. Homeostasis means all the processes aimed at preserving the balance and fulfilling the organic functions properly.

The other options are not correct because:

    A. Digestion is the process by which nutrients are converted into small molecules that are easily absorbed by the body.

    C. Excretion is the process of eliminating waste from metabolic and organic processes.

    D. Disequilibrium is the term applied to the failure or loss of ideal conditions or balance.

Answer:

In order for a metamorphic rock to become a sedimentary rock, the rock must undergo erosion. Once the rock has eroded, it will produce rock fragments or sediments which accumulate to form a sedimentary rock. ... In turn, when igneous and sedimentary rocks are exposed to heat and pressure, the rocks become metamorphic.

Explanation:

hope this helps

Answer:

One pathway is that an igneous rock can apply heat and pressure to the rock which will become metamorphic. Another pathway is that a metamorphic rock can be changed by heat and pressure to form into a different metamorphic rock.

Explanation:

Answer:

Crossing over is the exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis, which results in new allelic combinations in the daughter cells.

When chromosomal homologs communicate with one another during Meiosis I's metaphase, crossing over takes place.

When chromosomes of the same type are paired together during meiosis, a biological event called crossing over takes place.

Parts of the chromosome can be exchanged when two chromosomes, one from the mother and one from the father, line up. The same genes may be present on the two chromosomes in different versions.

The exchange of genetic material between non-sister chromatids of homologous chromosomes occurs during crossing over, an enzyme-mediated process. It happens during meiotic prophase I's pachytene stage.

Crossing over occurs during Meiosis I's metaphase when chromosomal homologs interact with one another.

Thus, this way, crossing over takes place during meiosis.

The question is incomplete; the complete question is;

Root cells of plants take in some minerals from the surrounding soil by spending energy. After the plant obtains enough minerals to maintain health, the plant will continue to absorb minerals from the soil. Which reason best explains why root cells need to spend energy in order to transport some minerals into cells?

Root cells are unable to use sunlight energy for mineral uptake.

Mineral concentration is higher in root cells than in the surrounding soil

Cell membrane pores in roots are too small for passive uptake of minerals

Cell membranes in roots lack proteins for the passage of minerals.

Answer:

Mineral concentration is higher in root cells than in the surrounding soil

Explanation:

Mineral uptake by plant roots occurs by active transport of ions into the cells of root hairs, this process requires energy.

The concentration of minerals in the soil is quite low. The root hair cells of plants possess carrier proteins that carry mineral ions and move them into the cell against existing concentration gradient. This process requires energy and is known as active transport.

Answer:

Explanation:

Ribosome works with ribonucleic acid to produce a functional protein. Translation takes place at the ribosome.

The endoplasmic reticulum helps in transport of proteins that are made by the ribosomes and folds them into sacs that are called cisternae from where it is moved to the Golgi apparatus.

Golgi apparatus served as store house for molecules that moved from endoplasmic reticulum. They are then released from the Golgi apparatus in what are called secretory vesicles into the cytoplasm.

Answer:

See the answer below

Explanation:

The nucleus is a double membrane organelle that is responsible for controlling the activities of the cell. It contains the DNA which carries the gene and the hereditary information of the cell.

The nucleoli are small spherical structures that are located within the nucleus which function in the formation of the ribosome and hence, important for protein synthesis in the eukaryotic organisms.

The ribosomes are structures within the cell which represent the site of protein synthesis. During protein synthesis, the mRNA and the tRNA attach themselves to the ribosome to form the translation complex for the initiation of protein synthesis.

The Golgi apparatus is a system of membrane responsible for the packaging and secretion of proteins and lipids within the cell.

The uneven heating of the Earth's surface leads to the formation of large global wind systems. The surface currents of the oceans are in turn driven by these global wind systems. Thus, option B is correct.

Large-scale surface ocean currents are propelled by global wind systems that are fuelled by solar energy. These currents transport heat from the tropics to the poles, altering the climate on a local as well as global scale.

Friction from the global winds, which both follow the same basic circulation, clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere.

Warm water and precipitation are transported from the equator to the poles by ocean currents, whereas cold water is returned to the tropics from the poles.

Therefore, The pattern of global ocean currents is one of the factors that drives global winds.

A situation that is commonly caused by acid rain is the dying off of fish and birds in freshwater habitats. Thus, the correct option for this question is B.

Acid rain may be defined as a type of precipitation that correspondingly include acidic components, like sulfuric acid, nitric acid, etc. that fall to the ground from the atmosphere in wet or dry forms like rain, fog, hail, etc.

The pH of acid rain is generally low compared to normal water. So, it causes numerous impacts on the earth's surface. But the most consequential influence of acid rain is the destruction of fish and birds in freshwater habitats.

It generally lowers the pH of the freshwater ecosystem and makes it unfavorable for many organisms like producers, small fishes, birds, etc. They cannot adapt themselves to such lower pH and have to dye off.

Therefore, the correct option for this question is B.
