Answer:

Drug abuse affect the way brain receives and process information

Explanation:

Drug abuse can be defined as the use of drug in amounts or by methods which are harmful to the individual or others.

Drugs affects the way neurons send, receive, and process signals via neurotransmitters. Some drugs, such as marijuana and heroin, can activate neurons because their chemical structure mimics that of a natural neurotransmitter in the body. This allows the drugs to attach onto and activate the neurons. Although these drugs mimic the brain's own chemicals, they don't activate neurons in the same way as a natural neurotransmitter, and they lead to abnormal messages being sent through the network.

Drugs such as amphetamine or cocaine, can cause the neurons to release abnormally large amounts of natural neurotransmitters or prevent the normal recycling of these brain chemicals by interfering with transporters. This disrupts the normal communication between neurons.

Which of the following accurately describes the role of energy in cellular respiration?

zmey [24]

Answer:

The correct answer is option energy is a product.

Explanation:

Cellular respiration is a process in which oxidation of food or glucose takes place to produce energy. This process proceeds in four processes: glycolysis, oxidative carboxylation, Krebs cycle and electron transport chain.

All of this process produces energy in the form of ATP or energy equivalents like NADH and FADH₂.

1. Glycolysis produces- 2 ATP, 2 NADH,

2. Oxidative carboxylation produces- 2 NADH,

3. Krebs cycle produces- 2 ATP, 6 NADH AND 2 FADH₂ and

4. Electron transport chain produces at last- 24 ATP from these reducing equivalents.

Thus, option energy is a product is a correct option.

Nata [24]

Answer:

The correct answer is option E) "Nondisjunction at either meiosis I or meiosis II in the mother".

Explanation:

Nondisjunction is a phenomena at which chromosomes are not properly separated during anaphase. This can either happen at meiosis I or meiosis II during oogenesis. Nondisjunction would explain the XO chromosomic condition of the daughter with Turner syndrome as well as the X-linked recessive allele of the red green color blindness. Nondisjunction happened in the mother because the father could not inherited an X-linked condition.

4) If a dead organism is preserved as a fossil, which body tissues are most likely to survive? Why?

IrinaVladis [17]

The answer is hard tissue.

Usually, hard tissue, such as bones and teeth or exoskeleton is much more preserved than soft tissue (organs, skin, etc.). Fossils become fossils by a process of mineralization. Hard tissues are more mineralized during life than organs. So it is no surprise that hard tissues take part in the process of mineralization and is preserved in fossils, unlike soft tissues.
