Acid-Fast Bacteria possess a unique cell wall architecture different from both gram negative and gram positive bacteria. The thick outer mycolic acid layer renders acid-fast bacteria resistant to gram stain.
The process is called meiosis.
Meiosis is a process in which the sperm and egg collide fusing both of their 23 chromosomes to produce a full 46 chromosomes that pass the genome to the offspring.
A substance that can not be broken down into any simpler substance is called an element.
The answer is; C
Gene therapy is still not considered safe and has not been approved for humans, especially due to errors in inserting of DNA at the target site and also random relapse of the DNA from its inserted site. Gene therapy, however, can be sanctioned when its benefits outweigh its risks such as in terminally ill patients - with the approval of the patient and local relevant policies/authorities. Gene therapy, today, is being tested with innovative tools called CRISPR/Cas9.
Answer:
intensity with which the rats pressed the lever
Explanation:
In research, there are two main variables which are <u>dependent</u> or <u>independent</u>.
Independent variables are controlled or manipulated by the experimenter and the independent variable in this experiment is the amount of light exposure.
The response or outcome, which is then measured is the dependent variable. In this experiment, the dependent variable is the intensity with which the rats pressed the lever with varying exposure to light.
In summary, the independent variable has a causal effect on the dependent variable so in this experiment the amount of light exposure has a casual effect on whether the rats would press a lever more.
