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

When a genotype of a guinea pig is "Hh" (select all that are true)
One chromosome of the homologous pair has a sequence that results in hair and one chromosome has a sequence that results in no hair
One copy of the "H" allele on the homologous chromosome is enough to make the guinea pig have hair since both alleles are transcribed and translated
Only one of the chromosomes in the homologous pair carry the genetic sequence to make hair
Both chromosomes in the homologous pair carry the genetic sequence to make hair
Answer:
One chromosome of the homologous pair has a sequence that results in hair and one chromosome has a sequence that results in no hair
One copy of the "H" allele on the homologous chromosome is enough to make the guinea pig have hair since both alleles are transcribed and translated
Only one of the chromosomes in the homologous pair carry the genetic sequence to make hair
Explanation:
Hairy is dominant over hairless. If there was a hairless guinea pig here instead, we would know its genotype. It would be hh. Remember any time a dominant allele is present it is expressed in the phenotype, so if the phenotype is not the dominant one, we know the genotype must contain two recessive alleles.
These are the factors that is true, When a genotype of a guinea pig is "Hh"
• One chromosome of the homologous pair has a sequence that results in hair and one chromosome has a sequence that results in no hair
• One copy of the "H" allele on the homologous chromosome is enough to make the guinea pig have hair since both alleles are transcribed and translated
• Only one of the chromosomes in the homologous pair carry the genetic sequence to make hair

Why is carbon so important for living things
Answer:
Organic compounds make up the cells and other structures of organisms and carry out life processes. Carbon is the main element in organic compounds, so carbon is essential to life on Earth. Without carbon, life as we know it could not exist.

Nutrients in excessive amounts enter water systems, causing algal bloom.
Answer: Nutrient pollution is caused when too many nutrients, primarily nitrogen and phosphorus, are added to water bodies. The excess nutrients act as fertilizers, causing excessive algae growth. It is common for nutrients to run off the land in urban areas, where lawn and garden fertilizers are used.

What ideas were changing in the scientific community at the time of Darwin's travels? How might those new ideas influenced Darwin?
Answer and Explanation:
At the time of Darwin's travels, the scientific community was beginning to abandon ideas linked to creationism to adopt more scientific and testable concepts, less linked to religiosity. Darwin was very influenced by these new concepts and decided to study a way to apply them to the biological diversity that planet earth presented. He wanted to explain this diversity through scientific data, obtained by experiments and logical reasoning, without the interference of creationist concepts and that would show how life on earth changes over the years and how species of living beings were created. This was one of the kicks that made him start his travels and his studies on biological evolution.
Microbeads are tiny, smooth, plastic spheres found in common household products such as facial soap. These beads, measuring from 0.0004 to 1.24 mm, roughly the size of some fish eggs, are too small to be removed by water treatment systems. Thus, they end up in rivers, lakes, and other bodies of water. The accumulation of these microbeads is an environmental concern for aquatic biologists because microbeads
(1) make the lakes and rivers cloudy and dirty, affecting their appearance
(2) may stick to some household water pipes, preventing drainage problems
(3) could be mistaken for food by some species, working their way up the food chain
(4) could clog fishing nets, affecting the ability of fishermen to catch fish
Answer:
(3) could be mistaken for food by some species, working their way up the food chain
Explanation:
Microbeads, such as other microplastics, can affect wildlife in many ways, but mostly by
IngestionIntroduction and transference in the trophic webInteraction with other contaminantsMicroinvertebrates, bacteria, and viruses colonize these microplastics and can be transported long distances.Organisms like mollusks, crustaceans, fishes, birds, turtles, among many others, might confuse these elements with food and eat them. Microbeads might float or accumulate in sediments and be ingested by different benthonic species. The ingestion of microbeads by inferior links in the trophic web means a direct entrance in the trophic web where many superior links are affected too while feeding with already contaminated prey.
The ingestion of microbeads can cause a significant impact on the growth, development, and reproduction of freshwater and seawater species.
Microbeads, like other microplastics, characterize for their durability in time and resistance, which means that the ones that are already in the oceans and rivers will last there for centuries.

Tetrodotoxin is a potent toxin found in a variety of organisms including the pufferfish. The toxin binds to the extracellular side of the Na+ channel and prevents channel opening. This leads to paralysis of muscles, including the diaphragm. Death from respiratory failure can occur after ingestion of as little as 1 mg of the toxin. Why does this toxin cause paralysis? Question 7 options: The axon membranes become over-depolarized. The Na+ channels remain in the inactive, refractory state. The Na+ channel does not open wide enough to allow enough Na+ through the channel. The membrane depolarization is not amplified along the axon.
Answer:
The correct answer is - The membrane depolarization is not amplified along the axon.
Explanation:
Tetrodotoxin, a neurotoxin present in the liver and gonads of Marine organisms. it can inhibit the soidum channels which means it blocks the entering of the sodium in the cells or neurons if consumed it and it can lead to neurological and gastrointestinal disorders.
These toxins block the signals to move along the nerves to muscles In absence of sodium action potential cannot be sent along the axon by blocking the sodium channels. This results in weakening and paralysis.

What could be inferred from suntans?
Group of answer choices
A tan might indicate sun damage to the skin.
Tanning produces healthier skin.
A tan strengthens the elastic in the skin.
Tanning makes skin look younger.
Answer:
A tan might indicate sun damage to the skin.
Explanation:
Tanning is the process by which the skin is exposed to the ultraviolet rays that comes from the sun with the purpose of producing a dark-brown coloration called a TAN.
A tan achieved by exposure to the sun can actually indicate that a person's skin is undergoing damage from the UV rays of the sun, hence, the skin responds by producing a protein called melanin, which protects the skin and later forms the dark coloration- tan. From this explanation, tan is got in response to a damaging signal received by the cell, hence, a tan might indicate sun damage to the skin.
Describe the role of gravity in maintaining the atmospheric layer around Earth. I will mark as brainliest
Answer:
Hi so the answer is that Gravity pulls the gas molecules towards Earth's center. The pull of gravity is stronger closer to the center at sea level. Air is denser at sea level where the gravitational pull is greater. Gases at sea level are also compressed by the weight of the atmosphere above them.

El aparato circulatorio. B. El aparato circulatorio, digestivo y respiratorio. C. El aparato respiratorio. D. El aparato respiratorio y circulatorio.
Answer:
C. El sistema respiratorio.
Explicación:
El sistema respiratorio es un tipo de sistema en el que los animales toman del medio ambiente los materiales necesarios para sus actividades vitales. Los pulmones son el órgano principal del sistema respiratorio en el que el gas de oxígeno entra al cuerpo y se almacena en los pulmones a través de la inhalación. La hemoglobina que extrae el gas de dióxido de carbono de la célula lo desecha en los pulmones y carga el oxígeno necesario para el proceso de respiración. El dióxido de carbono se elimina de los pulmones mediante la exhalación.
