Answer:
Chargaff's rules state that DNA from any species of any organism should have a 1:1 protein stoichiometry ratio of purine and pyrimidine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine
One of the major concerns about seawater desalination is its high expense. Another concern is the disposal of leftover brine from the desalination process back into the ocean, which harms marine life. Discuss whether these two concerns are enough to prohibit the widespread use of desalination as a source of drinking water.
Answer:
Yes.
Explanation:
Yes, these two concerns are enough to prohibit the use of desalination as a source of drinking water because this method is too expensive as well as bad for the marine environment. First, this desalination process is too expensive which is non-economical for the country while on the other hand, it greatly damaged the aquatic animals so this method must be stopped due to its adverse effect on both economics as well as environment.
What is NOT a function of the reticular formation?
a. sleep b. breathing c. memory d. pain transmission
Answer:
c. memory
Explanation:
Memory is not a function of the reticular formation. Sleeping, breathing, and pain transmission all are the functions of reticular formation. Thus, the correct option is C.
What is reticular formation?
Reticular formation is a part of the pons region of brain which controls the sleep-wake cycle and also filters stimuli to separate out relevant background stimuli from irrelevant ones.
Reticular formation is one of the phylogenetically earliest parts of the brain and it is crucial for controlling some fundamental processes such as sleeping, breathing, and pain transmission.
The reticular formation is an essential process for the numerous activities of the brainstem. It is located strategically amid the significant nuclei in the brain cells and the nerve fibers that traverse it. The reticular formation looks like an intricate web network.
Therefore, the correct option is C.

How will photosynthesis and respiration keep you alive, and what do you need to do?
Explanation:
While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere. The exchange of carbon dioxide and oxygen during photosynthesis (Figure below) and cellular respiration worldwide helps to keep atmospheric oxygen and carbon dioxide at stable levels. (hopefully this helps)

Q. How is the sex of the child determined in human beings ?
Please answer dis also..thanks!
➜ In human beings, sex of the child depends upon which kind of male gamete fertilise the female gamete. If sperm carrying X chromosome fertilises the ovum carrying X chromosome, then the child born will be a girl. If a sperm carrying Y chromosome fertilises the ovum which carries X chromosome, then the child born will be a boy.

Based on the information given, state ONE way the bag or its contents will have changed by the next day. Support your answer with an explanation. *
Answer:
The size of the bag will shrink due to movement of water molecules out of the bag into the beakerdue to osmosis.
Explanation:
The difference in concentration between two regions results in a phenomenon known as diffusion.
Diffusionnis the process by which molecules of a substance move from regions of higher concentration to regions of lower concentration until equilibrium concentration is reached by the two regions. Water molecules moves across regions of different concentration through a semipermeable membrane in a special form of diffusion known as osmosis.
Osmosis refers to the movement of water molecules from regions of high concentration (dilute solutions ) to regions of low concentration (concentrated solutions ) through a semipermeable membrane until equilibrium is attained.
The solution in the bag is less concentrated than the solution innthe beaker. The bag serves as a semipermeable membrane allowing water molecules to move out of it into the beaker due to the difference in concentration of the two solutions. As a result, the size of the bag shrinks while the level of the solution in the beaker rises as it becomes less concentrated.
