Answer:
See the answer below
Explanation:
An open system is a type of thermodynamic system in which energy and matter are being exchanged between the system and the surrounding. It is like boiling soup in an open pot. The opening allows for the addition of materials (matters) into the soup and energy is exchanged through the heating. A good example is found in biological organisms. They consume matters and exchange energy with the environment by carrying out work.
A closed system is a type of system in which there is no exchange of matter between it and the environment. However, there is an exchange of energy. It is like boiling water in a closed pot. Nothing can be added into the pot due to the closure but energy can be transferred through the heating of the pot.
An isolated system allows for neither energy nor matter exchange with the surrounding. It is like a closed food warmer that allows for nothing to enter or leaves it.
Answer: Open systems are energy that can be transferred between the system and its surroundings. Close systems are systems that do not transferred to its surroundings. Isolated systems is a thermodynamic system which cannot exchange either energy or matter from outside its boundaries of the system.

he most common source of osteomyelitis is an infection that migrates via the bloodstream. direct invasion from a fracture. surgical contamination. a joint prosthesis.
The correct answer is A. An infection that migrates via the bloodstream
Explanation:
Osteomyelitis is a serious condition, in which an infection develops in bones. This causes symptoms such as pain, inflammation, and can lead to the spread of the infection to other tissues or bone necrosis if it is not treated. In terms of causes, this condition develops when the bone is exposed to bacteria or similar that causes the infection, this can occur during surgeries or fractures. However, the most common source of infection is via bloodstream this means the bacteria or germ is in the blood and it enters the bone through the bloodstream. Also, once the bacteria or germ is in the bone it causes the infection.

Where does that air go as a result?
Answer:
Air go from one place to another due to difference in temperature of land and sea.
Explanation:
Air go as a result of wind from one place to another. Air moves from land to sea is called land breeze and from sea to land is known as sea breeze. This will occur when there is difference in temperature between sea and land. Sea breeze occurs at afternoon while land breeze occurs at night till morning. Warm air produces low pressure and cold air produces high pressure so when warm air rises, cold air takes its place and this cycle continues.

An inflorescence is a flower group, which are clustered nearby in a stalk, which is also known as the peduncle. In lily, the individual flower was found, not quite as groups. However, the flowers are set as an inflorescence in the oak tree. It refers to a group or community of a flower cluster borne on a flower, which is traditional flowers of oak are called catkins, that's why 'inflorescence, oak' is the reaction.Acidification of the stomach uses all of the following types of transport EXCEPT: A. channels. B. pumps. C. antiporters. AND. symporters. E. All of these are used by parietal cells.
Answer: Option E.
All of these are used by parietal cells.
Explanation:
Parietal cells are found in the stomach and they produced gastric acid(Hcl)..
HCl is produced when water mixed with carbondioxide in the parietal cell to produced carbonic acid which is catalyses by carbonic anhydrase. The carbonic acid then dissociates into hydrogen ion and carbonate ion.
Parietal cell produce HCl due to histamine (via H2 receptors), acetylcholine (M3 receptors) and gastrin (gastrin receptors).
Therefore it uses channels, pumps, antiporter.

This question is incomplete; here is the complete question:
All of the following are examples of organic matter soil except
A. Decaying plants
B. Bacteria
C. Fungi
D. Water
The answer to this question is D. Water
Explanation:
Organic matter derives from living beings, due to this, organic matter is considered as a biological product. In this context, materials such as decaying plants are organic matter because they derive from living organisms and contain biological molecules (most contain carbon). This category does not apply to water, which is composed of hydrogen and oxygen and does not derive from living beings. Thus, the one that is not organic matter is water.
Answer:
D. Water

atch the term with the correct cellular process or definition. - A molecule containing genetic information - RNA base that pairs with adenine - Carries amino acid to ribosomes - The site of protein synthesis - DNA base that pairs with adenine - Carries the genetic code to ribosomes A. mRNA B. DNA C. tRNA D. Thymine E. Uracil F. rRNA G. Ribosome
Answer:
A molecule containing genetic information - DNA
RNA base that pairs with adenine - Uracil
Carries amino acid to ribosomes - tRNA
The site of protein synthesis - Ribosome
DNA base that pairs with adenine - Thymine
Carries the genetic code to ribosomes - mRNA
Explanation:
DNA is the molecule that is responsible for conveying genetic information in living organisms. It is made up of deoxyribose sugar, a phosphate group, and purine/pyrimidine bases. The purine bases consist of adenine and guanine while the pyrimidine bases include thymine and cytosine. As a matter of rule in the DNA, Adenine base always pairs with Thymine base while the Cytosine base always pairs with Guanine base.
RNA on the other hand is single-stranded unlike the double strands of DNA. It has all the nucleotide bases present in DNA except that the Thymine bases are usually replaced with Uracil.
There are three types of RNA:
the messenger RNA that is responsible for carrying genetic code from DNA to the ribosome for translation purpose, the transfer RNA responsible for carrying amino acids to ribosome during the translation process; and the ribosomal RNA which forms an integral part of the subunits of the ribosome itself.A group of organs working together to achieve a common function is known as:

Membrane-bounded vesicles that contain enzymes for oxidizing small organic molecules with the formation of hydrogen peroxide are Group of answer choices
Answer:
peroxisomes
Explanation:
The peroxisomes represent one of the organelles of the cell. They are usually small and characterized by membrane-bound vesicles that contain oxidative enzymes.
The enzymes in peroxisomes are involved in the oxidation of organic molecules - a process that leads to the formation of hydrogen peroxide. The later is further converted to water and oxygen by the constituent catalase enzyme of the peroxisomes. Fatty acids are also oxidized in peroxisomes but instead of hydrogen peroxide, acetyl groups that are utilized in other biosynthetic reactions are produced.

Answer:
C. Lithosphere
Explanation:
many endangered species are predators that belong to the higher trophic levels. Which is the process that primarily affects animals at the highest trophic levels?
Answer:
Top predators at the highest trophic levels eat lower-level predators and herbivores
Explanation:
A trophic level is defined as one group of organisms in the ecosystem occupying the same level in the food chain, which is composed of different levels (primary, secondary and higher levels). Top predators at the higher levels maintain the trophic balance by eating other species that eat on primary producers/consumers, thereby favoring the homeostasis of the ecosystem.
g In humans and higher primates, _____ is the final product of purine base catabolism and is excreted in urine. However, its inadequate excretion is a cause of a disease called ______
Answer: Humans and greater primates excrete water, broken down proteins and Urea. Many things cause unusual urine, Urea gives urine its yellow color a lack of urea can mean kidney failure. however it's hard to tell a lack of urea by just looking at urine as drinking excessive amounts of water turns the color clear and drinking caffeine turns the color reddish or brown so lab testing must be done
