A. True

B. False

Answer:

Mist is made of water vapor.

Explanation:

The bathroom mirror and the fog that the bathroom presents after someone takes a shower, is formed by water vapor. This water vapor is formed by the hot water from showers, which evaporates. This water vapor is what forms the mist, however, when this mist touches the surfaces of the bathroom, such as the mirror, it becomes water again and that smothers the mirror. The mist becomes water when touching the mirror because of the difference in temperature between them, as the mist is hot and the mirror is cold. This happens through the condensation of water.

Answer:

a. Drug abuse

b. Inhalants

c. Stimulants

d. Neonatal abstinence syndrome

e. Club designer drugs

f. Depressants

Explanation:

Drug abuse can be defined as the excessive use of drugs that can be harmful to the individual or to others, which is associated with social, behavioral, physical and job-related problems. Inhalants drugs (e.g., glue, cocaine) are volatile drugs whose inhalation may induce psychoactive and/or mind-altering effects. Stimulant drugs (e.g., cocaine, amphetamines) are drugs that excite body functions by accelerating the activity of the central nervous system (CNS), while depressant drugs (e.g., alcohol) slow down the CNS. Neonatal abstinence syndrome occurs when a neonate withdraws from certain drugs (usually opioid drugs which interact with opioid receptors) to which he/she was exposed before birth. Finally, designer drugs (e.g., ecstasy, ketamine, LSD) are drugs synthesized in illegal labs which are commonly known as “club drugs” because they are often used and sold in nightclubs.

- Cruzamiento parental: AABB  x aabb

Genotipos F1: AaBb

- Cruzamiento F1: AaBb x AaBb

Fenotipo: 100% plantas altas púrpuras

- Genotipos F2:  AABB (1/16); Aabb (1/16); aaBB (1/16); aabb (1/16); AaBb (4/16); AABb (2/16); aaBb (2/16); AaBB (2/16); Aabb (2/16)

- Fenotipos F2: 9/16 A-B- (altas púrpuras); 3/16 A-bb (altas blancas); 3/16 aaB- (enanas púrpuras); 1/16 aabb (enanas blancas)

Explanation:

Un cruzamiento dihíbrido refiere a un tipo de cruzamiento entre dos parentales que difieren para  dos pares de alelos (AABB x aabb). Si consideramos dos loci de dominancia completa, un cruzamiento dihíbrido producirá una F1 heterocigota para ambos genes donde la progenie expresará ambos rasgos dominantes. Como resultado de la distribución independiente expresada en la segunda ley de Mendel, La F2 de este tipo de cruzamiento producirá un proporción fenotípica 9:3:3:1; es decir 9 individuos con ambos rasgos dominantes (A-B-), 3 con el rasgo uno dominante (A-bb), 3 con el rasgo dos dominante (aaB-) y 1 con ambos rasgos recesivos (aabb).

Answer:

A myelinated axon conducts impulses faster than a non-myelinated axon. ... Therefore, in myelinated neurones, the nerve impulse is said to jump from node - to - node, a impulse pathway known as Saltatory Conduction. This means that the action potential does not have to travel along the whole length of the myelinated axon

Answer:

True

Explanation:

Symbiosis is a type of relationship or interaction between two different biological organisms/species by which both are benefited. The bees such as mason bees are pollinators. Pollinators are animals (especially insects) that help the development of seeds and the fruit surrounding seeds by the pollination of flowers, i.e., by the transference of pollen from male anthers of a flower to the female stigma. During this process, pollinators eat nectar, which is a sweet energy-rich liquid secreted by flowers. In consequence, both species (i.e., plants and mason bees) are benefited from this interaction.

Answer:

Potential Energy.

Explanation:

Potential energy, stored energy that depends on different parts of the system's relative position. When compressed or stretched, spring has more potential energy.

A stainless steel ball has more energy than it had when it fell to the world. It is able to do more work in the raised position.

Potential energy is a system's property and not a single body or particle. The earth-consistent system and raised ball, for instance, have greater potential energy as the two are more distinct.

Answer:

oxygen

Explanation:

Without oxygen aerobic respiration cannot occur. Therefore ATP is produces by anaerobic reparation which is from glycolysis only. Lactate/ lactic acid is formed when glycolysis is the only production of ATP.

Explanation:

Answer:

A single round of DNA replication occurs in the parent cell, followed by two distinct nuclear division cycles. The process produces four haploid daughter cells, each with half as many chromosomes as the diploid parent cell.

Explanation:

During sexual reproduction, meiosis produces the sex cells that combine to make new children.

Meiosis is a type of cell division that results in the formation of sex cells (egg and sperm). And that is brought together to generate new progeny through the act of sexual reproduction.

Meiosis generally results in 4 haploid daughter cells, meaning half no chromosomes are contained in diploid cells.

when there is high concentration of co2 in our body then respiratory centre ( medulla and pons) get activated and it increase rate of respiration which decreases co2 concentration

The apneustic (stimulating) and pnuemotaxic (limiting) centers of the pons work together to control rate of breathing.

Medulla is defined as the lowest part of the brain and the lowest portion of the brainstem. The medulla oblongata is connected by the pons to the midbrain and is continuous posteriorly with the spinal cord, with which it merges at the opening (foramen magnum) at the base of the skull.

The medulla sends signals to the muscles that initiate inspiration and expiration and controls nonrespiratory air movement reflexes, like coughing and sneezing.
