Which of the following conditions is necessary for natural selection to occur? (3 points)
More organisms are born than can survive.
Each individual organism that is born must survive.
There must be no mutations among organisms.
There must be no variation among organisms.
Answer:
A
Explanation:
The condition that is necessary for the natural selection to occur is that each individual organism that is born must survive. The correct option is B.
What is natural selection?Natural selection is the process by which living organism populations adapt and change.
Individuals in a population are naturally variable, which means they differ in some ways. This variation indicates that some people have traits that are better suited to their environment than others.
Natural selection, Darwin proposed, is a mechanism for evolution in which heritable traits that help organisms survive and reproduce become more common in a population over time.
The phrase "survival of the fittest" refers to the process of natural selection, a mechanism that drives evolutionary change.
The condition for natural selection to occur is that each individual organism that is born must survive.
Thus, the correct option is B.

How is oxygen carried from the lungs to the tissues?
a. It binds to a protein called hemoglobin in red blood cells
b. It is carried by cilia through the bronchioles
c. It leaves the alveoli and enters mucus
d. It leaves the bronchi and enters the capillaries
Answer:
It binds to a protein called hemoglobin in red blood cells.
Explanation:
I took the quiz.
Oxygen gas is carried in the body from the lungs to the tissues by binding to a protein called as hemoglobin in red blood cells. Thus, the correct option is A.
What is Hemoglobin?Hemoglobin is abbreviated as Hb or Hgb. It is the iron-containing oxygen-transport metalloprotein which is present in the red blood cells of almost all the vertebrates as well as the tissues of some of the invertebrates.
Hemoglobin is the main protein in the red blood cells which carries oxygen gas to body's organs and tissues and it transports carbon dioxide gas from the different body organs and tissues back to the lungs.
Therefore, the correct option is A.

Explain how DNA results in the expression of a gene using the following words: DNA, mRNA, tRNA, gene, transcription, and translation
Explanation:
in order for a gene to even be transcribed, it must be "turned on" or "expressed" meaning the nucleotides have moved away from each other. after it's expressed, the gene will unwrap and continue on with transcription, and make mRNA copy of a DNA strand. once RNA is made it will leave nucleus and enter cytoplasm to find a ribosome. once it attaches to ribosome, translation begins, and a tRNA will bind to anti-codon, and the building of a polypeptide/protein will begin.
Oxygen is transported by _____to the_____ where it is used to break down the ______ into water, carbon dioxide, and usable energy.

When unnatural pollutants are exposed to sunlight and heated up, they create
a. ozone
b. carbon dioxide
c. nitrous oxide
d. greenhouse gases
When unnatural pollutants are exposed to sunlight and heated up, they create ozone. The correct option is a.
What are unnatural pollutants?
It is the resulting pollution from human activity. It covers the use of fossil fuels in manufacturing, transportation, and thermoelectric power plants, as well as industrial gas emissions, mining, processing, and stone crushing.
The physical degradation or contamination of the environment caused by the release of hazardous, dangerous, or toxic chemical substances is known as pollution.
Oxides of nitrogen (NOX) and volatile organic compounds (VOC), commonly referred to as hydrocarbons, undergo chemical interactions that result in ozone. Both close to the earth and high in the atmosphere, this reaction is possible.
Therefore, the correct option is a. ozone.

Which of the choices below gives the best "big picture" snapshot of what is happening in the body?
Question 10 options:
Specialized cells have specialized DNA that allows them to produce specialized proteins needed by an individual cell
The brain sends mRNA as a messenger to specific cells telling them to send proteins to copy DNA from the ribosomes so other cells can get a copy of those genes.
Every cell in the body contains the entire DNA genome. Specialized cells turn on specific genes to make specific proteins, which are then released for use throughout the body.

Explanation:
a force has direction and contact true or false
Answer:
Because a force is a vector that has a direction, it is common to represent forces using diagrams in which a force is represented by an arrow. In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. ... A force has both magnitude and direction, making it a vector quantity.

A company manufactures a chemical which acts as a strong chemical solvent. The chemical has a negative impact on the environment and human health when non properly disposed of. In order to be in compliance with the cradle to grave' tracking expectations of the federal government, the company must most clearly understand and abide by which law to track the manufacture and disposal of this chemical? A) Clean Air Act B) Clean Water Act Safe Drinking Water Act D) Resource Conservation and Recovery Act
Answer:
D) Resource Conservation and Recovery Act
Explanation:
The Resource Conservation and Recovery Act of 1976 was passed to ensure that the processes involved from the generation to the disposal of hazardous wastes are properly managed and meet up to health and environmental standards. The cradle represents the generation of the wastes while the grave represents the disposal of the wastes.
The company generating the hazardous waste is also responsible for other processes such as the transportation, treatment and storage of the waste.
