As an individual ages, new neurons and dendrites appear, but others atrophy. Compared to when they were adolescents, adults have fewer neural connections and their brain size _____ as they continue to age.
The brain and central nervous system shrink as we age.
What happens to the brain when we age?The brain is one of the most important organs in our body because all the nerve signals are produced there for our body to function.
In the brain we find nerve connections through neurons. A particular aspect of them is that during childhood and adolescence they multiply as we learn new things.
However, once we reach the stage of old age, these nerve connections deteriorate and are reduced, therefore, the size of the brain and the central nervous system decreases.

summary of what occurs during transcription
The act of copying information from a strand of DNA into a fresh messenger RNA molecule is called transcription (mRNA).
DNA preserves genetic material as a reference or template safely and permanently in the cell nuclei.
The process of gene expression starts with transcription. A gene's DNA sequence gets transcribed into RNA during this process. The DNA double helix must unwind close to the gene being transcribed before transcription can begin. A transcription bubble is the term for the area of opened-up DNA.

Two students are planning an experiment that will test how planaria (aquatic flatworms) respond to different environments. They will conduct two investigations—one that tests the worms’ responses to different water temperatures and one that tests the worms’ responses to different levels of acidity. Student 1 wants to buy two groups of flatworms and use a different group for each investigation. Student 2 thinks the same group of worms should be used for both investigations.
Do you think either student’s method would give more accurate results? Why or why not? Explain your response.
Student 2 is correct and the same group of worms should be used.
What is an experiment?An experiment is the process by which we establish cause and effect relationships in science. The control variable are those that must be kept the same in the experiment.
We know that the experiment will only be valid if the research is carried out with the same group of worms. If different groups of worms are used, other factors may account for the results obtained.
Thus student 2 is correct and the same group of worms should be used.

Active and passive immunity involves all of the following except receiving mother's antibodies through breast-feeding. exposure to a pathogen either naturally or by vaccination. memory B cells responding to a second exposure to the same pathogen. the stimulation of a nonspecific immune defense. receiving mother's antibodies through the placenta.
Explanation:
Immunity is the ability of an animal to resist infection.
There are two types of immunity in the body; INNATE OR INHERITED IMMUNITY AND ACQUIRED IMMUNITY. Inherited immunity it is the type of immunity that one is born with. It is passed from parent to offspring.
Acquired immunity is immunity to particular infections that is not inherited but has developed in the animal's life as it interacts with its environment. Acquired immunity can develop naturally in which case it is called NATURAL ACQUIRED IMMUNITY OR ARTIFICALLY.
ACTIVE IMMUNITY is the form of acquired immunity in which the body produces its OWN antibodies against infections. While PASSIVE IMMUNITY is the form of acquired immunity in which an individual is PROTECTED AGAINST INFECTION BY RECEIVING ANTIBODIES.
NATURAL ACQUIRED IMMUNITY
when attacked by the same pathogens again, they don't became seriously ill. this is because memory cells are able to recognise the antigens and stimulate the immune system to produce antibodies against the pathogens. This is known as NATURAL ACTIVE ACQUIRED IMMUNITY. It develops when one recovers from an infection.
During pregnancy, the mother passes antibodies across the placenta to the foetus. At birth the baby gets antibodies from the mother through breast milk. This is natural passive acquired immunity.
What molecule is the final electron acceptor in the Electron Transport Chain?
The final electron-accepting molecule in the electron transport chain is oxygen.
Role of oxygen in the electron transport chainOxygen mainly acts as an electron acceptor in the electron transport chain. More specifically, it acts as the final electron acceptor to ensure that oxidative phosphorylation takes place.
Without this final electron acceptor, the electron transport chain will not be able to complete the cycle, and energy molecules in the form of ATP will not be formed.
