Consider the diagram of the basic structure of a bacterium. A diagram of a bacterium is labeled. Part A is the cell membrane, part B is the flagellum, part C is the nucleoid, and part D is the pilus. Which of the labeled structures in the image allows bacteria to exchange genetic material and thus evolve to be better pathogens?
Answer:
Part D: pilus
Explanation:
Conjugative pili allow for the transfer of DNA between bacteria and thus evolve to be better pathogens.
The structure in bacteria that allows them to exchange genetic material and evolve is the pili
Bacteria piliPili (pilus, singular) are thin, proteinous structures located on the surface of bacteria that serves as:
they help bacterial cells to attach to surfacesthey serve as channels for the transfer of genetic materials during conjugationWhen genetic materials are transferred through the pilus, gene recombination occurs and bacteria evolve as a result.

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.
Therefore, yes
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.
Answer:
that last one

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.

Which has the larger ratio of surface area to volume, a tennis ball or a soccer ball?
Answer: Soccer Ball
Explanation: Because it is bigger and could hold more air.
The answer is Soccer Ball. Just because it is bigger and could hold more air.
What is the ratio of the surface location to extent limits?The ratio of surface place to an extent limits the dimensions of the cell textbf{the size of the cell} the dimensions of the mobile. This is due to the fact that the quantity of mobile will increase swiftly, the mobile's floor region decreases, to the factor that the ratio of floor place to an extent is a small price.
The surface vicinity to extent ratio is important for cellular diffusion in addition to cell department. So that you can live, cells require nutrients and oxygen to skip into the cell via its cell membrane, and they require waste to go away from the cells within the contrary course.

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.

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.

Balanced Forces acting on an object will not change the object's motion. Unbalanced Forces acting on an object will change the change the object's motion.The net force on an object is the combined effect (the sum) of all the pushing and pulling forces actually acting on the object.
