How do particles move when a surface wave passes through a medium?
A. Parallel to the direction of wave motion
B. Perpendicular to the direction of wave motion
C. Both parallel and perpendicular to the direction of wave motion
D. Neither parallel nor perpendicular to the direction of wave motion
Answer:
perpendicular to the motion of the wave.
Explanation:
when in a medium, they only go up and down or back and forth meaning the wave won't ever move the left or right side of the particles, so it is perpendicular
hope this is trusted helper for brainly material
Answer: it’s both parallel and perpendicular to the direction of a wave motion

Explain the difference: a myelinated axon conducts impulses faster than non-myelinated axon of the same diameter
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

Entre una planta alta de color purpura (AABB) con otras planta enana de color blanco (aabb), ¿cómo será el genotipo y el fenotipo de la F1 Y F2?
Answer:
- Alelos:
Locus 1: A (alto); a (enano)
Locus 2: B (púrpura); b (blanco)
- 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).

5. Our nervous system and our skeletomuscular system help us react to stimuli. Give one example on how this helps us maintain homeostasis.
Answer
The nervous and skeletomuscular systems help maintain homostasis by regulating respiration.
Explanation:
The brain stem, consisting of the pons and medulla, represent the main respiratory center. According to Wikipedia, "an increased level of carbon dioxide in the blood, or a decreased level of oxygen, will result in a deeper breathing pattern and increased respiratory rate to bring the blood gases back to equilibrium."
This is an example of a homostastic response controlled by both of the organ systems referenced above.

For each phrase below, choose the most appropriate key term from the list above
a. The improper or unsafe use of a drug
b. A drug that is inhaled as vapors
c. a drug that temporarily increases energy and alertness
d. drug withdrawal occurring in newborn infants
e. laboratory made drugs that closely resemble common illegal drugs in chemical structure and effect
f. a drug that slows the body and the brain
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.

Why are third parties important in a political system?
Answer:
Third parties are important in a political system because they serve an important role in our political system by forcing major political parties to address new issues they might not have previously addressed very much. And third party candidates can also greatly impact an election by taking away votes from one of the major political party candidates.
Because the imaginary axis of the earth is inclined to the sun at the equator, the northern and southern hemispheres shine in different ways. When it is summer in the northern hemisphere of our planet, then it is winter in the southern hemisphere
Answer:
Yes.
Explanation:
Yes, when it is summer in the northern hemisphere of earth, then it is winter in the southern hemisphere. This change of season occur due to tilting of earth. The season of northern hemisphere and southern hemisphere are different and opposite to each other because both are present at opposite location on the earth surface. The tilting region experience winter season whereas the other regions experience summer due to direct sunlight.
As native mason bees visit flowers, they spread pollen while also consuming nectar from the plant. This is an example of symbiosis.
true or fasle
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.

Genetically modified organisms include microbes used in biotechnology that possess enzymes promoting antibiotic resistance. This could be a problem given the rise of antibiotic-resistant organisms. However, these engineered microorganisms do not pose a risk to public health. What do you think prevents them from spreading antibiotic resistance to pathogens outside the laboratory
Answer:
What prevents these microorganisms from spreading resistance outside the laboratory is that they are modified to not survive outside the laboratory environment.
Explanation:
Antibiotic resistant microorganisms are very dangerous and unfavorable, as they leave living beings completely completely defenseless to their attacks. However, there are microorganisms that have been modified in the laboratory, as shown in the question above, and do not present any risk to living beings, even if they develop resistance. This is because the modification that these microorganisms received makes them not survive the environmental conditions outside the laboratory, which causes them to die if they leave the laboratory.

Luisa went into the bathroom after her sister had a bath. It was full of mist and the mirror was covered with the a lot of liquid drops. What was the mist made of?
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.
