Describe the movement of oxygen and carbon dioxide in tissues other than the lungs?
Answer:
Gas Transport in the Human Body
Explanation:
Once the oxygen diffuses across the alveoli, it enters the bloodstream and is transported to the tissues where it is unloaded, and carbon dioxide diffuses out of the blood and into the alveoli to be expelled from the body.

How does sulfur in the air get moved to the soil.
Answer:
Sulfur can also fall directly from the atmosphere in a process called fallout. Also, the weathering of sulfur-containing rocks releases sulfur into the soil. These rocks originate from ocean sediments that are moved to land by the geologic uplifting of ocean sediments.

Which of the following cells is responsible for producing antibodies when antigens enter the body?
B lymphocytes or B-cells are responsible for producing antibodies when antigens enter the body.
What is Antibody?An antibody may be defined as a protein produced by plasma cells in response to a specific antigen.
The major function of an antibody is to eliminate disease-causing organisms which are known as pathogens and barricade them from contaminating human cells.
Plasma cells of the body produce B cells and memory. B cells play an essential role in producing antibodies while memory cells initiate the process of secondary infection.

Control of rickettsial infections requires _____.
regular bathing
antibiotics
insect control
quarantine
Answer:
insect control
Explanation:
The control of rickettsial infections requires the control of insects.
Rickettsial infections are caused by obligately intracellular Gram-negative bacteria that can only live inside a host organism. The host organisms are usually insects such as ticks, fleas, lice, etc. and a bite from any of the insects hosting the bacteria represents the only through which the infections are transmitted.
Hence, controlling the insects that serve as hosts for the bacteria will go a long way in controlling rickettsial infections.
Answer: insect control

ASAP!! In the past, plants and fungi were classified together into a single kingdom. What new scientific knowledge led to their current classification into separate kingdoms?
A. It was discovered that plants do not function as decomposers in ecosystems.
B. It was discovered that fungi lack body structures for locomotion.
C. It was discovered that plants could be unicellular.
D. It was discovered that fungi are heterotrophic.
Answer:
D
Explanation:
fungi are heterotropic therefore they cannot produce their own food. plants can since they are autotrophic
The new scientific knowledge led to their current classification into separate kingdoms as It was discovered that fungi are heterotrophic. Thus, option D is correct.
What are fungi?Fungi and plants are currently classified into two distinct kingdoms. However, due to some of their common observed features, they were once classified together as one kingdom. Fungi are a group of heterotrophic organisms that possess cell well while Plants are group of autotrophic organisms that also possess cell wall.
Previously, the observable similar features were the basis of classification of organisms. It was observed that fungi and plants were nonmotile i.e. cannot locomote, and possessed a fixed body structure that grew out of the soil (fungi mushroom).
Therefore, The new scientific knowledge led to their current classification into separate kingdoms as It was discovered that fungi are heterotrophic. Thus, option D is correct.

compare and contrast the rock cycle and the carbon cycle
Answer:
The rock cycle and water cycle overlap with erosion, transporting, and deposition.carbon atoms are used repeatedly on Earth and cycled between the atmosphere, hydrosphere, biosphere, and lithosphere through processes
Explanation:
The rock cycle and the carbon cycle are two different types of natural cycles that occur on earth. The difference include components, processes, time scale, human impact, and environmental implications.
What is the difference between rock cycle and carbon cycle?The rock cycle is a continuous process that occurs over millions of years, during which rocks are transformed from one type to another. There are three major types of rocks: igneous, sedimentary, and metamorphic. Each type of rock is formed through a different process.
The carbon cycle is the process by which carbon is cycled between the atmosphere, oceans, and living organisms. Carbon is essential for life, and is found in all living organisms. The carbon cycle is driven by photosynthesis, respiration, and decomposition.
During photosynthesis, plants absorb carbon dioxide from the atmosphere and use it to build organic molecules. These organic molecules are then consumed by other organisms, and carbon is transferred up the food chain.
When organisms die, their bodies are decomposed by bacteria and fungi, which release carbon dioxide back into the atmosphere.
In addition, carbon is stored in fossil fuels such as coal, oil, and natural gas, which are formed from the remains of ancient plants and animals. When these fuels are burned, carbon is released into the atmosphere, contributing to global warming.

What does the principle of conservation of matter say? How is this related to Earth's plates?
Answer: 1. Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass. 2. The movement of Earth's plates is driven by plate tectonics, illustrating how the flow of energy drives the cycling of matter—the flow of heat from radioactivity within the Earth drives plate tectonics. The rock cycle, plate tectonics, and the water cycle are all convection-driven.
Explanation:
Hope this helps. ^_^
The principle of conservation of matter states that any object can modify its physical and chemical state but during these changes, the mass of the substance remains the same.
After or before the change in the substance state the mass cannot be added nor can be removed.The tectonic plate's movement of the Earth tells us about how the energy circulates and drives the matter.The radioactivity flows the heat within the Earth's surface which drives the tectonic to move.To learn more about the principle of conservation of matter follow the link:

what does the chromatin do in the cell?
Answer: it's Chromatin
because Chromatin is a substance within a chromosome consisting of DNA and protein. The DNA carries the cell's genetic instructions. The major proteins in chromatin are histones, which Chromatin is located in the nucleus of our cells. The primary function of chromatin is to compress the DNA into a compact unit that will be less voluminous and can fit within the nucleus. Chromatin consists of complexes of small proteins known as histones and DNA. hope this helps have a nice day ❤️❤️❤️
