Which two substances are among the four major types of organic compounds made by living things?
A:Carbohydrates
B:Potassium
C:Water
D:Proteins
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.
Explanation:
Answer:
Carbon is the most important element to living things because it can form many different kinds of bonds and form essential compounds.
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

Los animales toman del medio los materiales necesarios para sus actividades vitales. Estas funciones la realizan: A. 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.

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

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 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.

Which of the following is true about the group Archaea?
A. Archaea has more genetic similarities to Bacteria than Eukarya
B. Archaea and Bacteria both have a nucleus
C. Bacteria and Eukarya are both prokaryotes
D. Archaea has more in common genetically with Eukarya than Bacteria.
Answer:
D. Archaea has more in common genetically with Eukarya than Bacteria.
Explanation:
Archaea are unicellular, prokaryotic microorganisms that differ from bacteria in their genetics, biochemistry, and ecology. Some archaea are extremophiles, living in environments with extremely high or low temperatures, or extreme salinity. Only archaea are known to produce methane.
Answer:
D. Archaea has more in common genetically with Eukarya than Bacteria.
Explanation:
Yes, archaea has more in common genetically with Eukarya than Bacteria. Archaea constitute a domain of single -celled organisms.

Would appreciate Brainliest if this helped you! Have a great day!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.
Explanation:
I really hope i helped , pleaseeee give me brainliest , have a nice day and thank you in advance :))) .

A scientist is comparing the sequences of related genes among three species. Two of the species have very similar sequences, while the sequence of the third species differs greatly from the others. T
Hi. The question you presented above is incomplete. This makes it impossible for this question to be answered. However, when searching for your question on the internet, I was able to find another question exactly like yours, which asked you to explain the evolutionary relationship between these three species. If that's the case for you, I hope the answer below will help you.
In a simplified way, we can infer that among the three species presented above, the third presented a faster evolution than the first two and this is what explains the difference between the gene sequences between the species. As the question presents, the three species have related genes, which indicates that they had a common ancestor, however the difference in the gene sequence of the third species shows that it evolved first, showing changes that cannot be noticed in the first two species that are evolving more slowly.
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.
