How do the sun and moon affect the tides?
Answer:
The Sun causes tides just like the Moon does, although they are somewhat smaller. When the earth, Moon, and Sun line up—which happens at times of full Moon or new Moon—the lunar and solar tides reinforce each other, leading to more extreme tides, called spring tides.
Which ACTN3 genotype (RR, RX, or XX) would provide these Olympic marathon athletes with an advantage, and why?
Answer:
XX
Explanation:
ACTN3 genotype i.e. XX provides advantage to the Olympic marathon athletes because it strengthens the fiber of the muscles. This gene is also called the gene of speed. This ACTN3 gene has a great influence on the type of fiber that makes body muscles, and they are also linked to strength and endurance so we can conclude that this gene provides benefits to the Olympic marathon athletes by giving strength to the fiber of muscles.
ACTN3 genotype is the gene encoding for the actinin of the skeletal muscle fibres. XX of the ACTN3 genotype will be advantageous for marathon athletes.
What is ACTN3 genotype and XX?ACTN3 genotype is the gene encoding for the protein of the skeletal muscles fibres that are associated with muscular performance. This protein is expressed in the myofibers with a high twitching ability and result in a high-velocity force.
The XX genotype provides strength to the muscles and is the gene coding for the proteins that give speed. They are also responsible for endurance and are beneficial for athletes.
Therefore, XX of the ACTN3 genotype is advantageous for athletes.

Why might parasitic roots have developed in plants like the mistletoe?
Answer:Mistletoe is a parasite – it steals water and nutrients from trees. Technically, it is a “hemiparasite”, which means that it can generate some of its own resources through photosynthesis – it just needs that energetic kick from the sun to fuel the biological siege and subsequent invasion of the tree

Answer:
1. A low- pressure weather system can cause a thunderstorm to develop.
2.Thunder is caused by lightning. When a lightning bolt travels from the cloud to the ground it creates a channel. Once the light is gone the air collapses back in and creates a sound wave that we hear as thunder.
3. One condition that is necessary for a thunderstorm include warm air and moisture.
4. The dangers of a blizzard include getting lost in the snow and freezing to death.
5. In my opinion, a hurricane would be the most difficult storm to face because hurricanes can severely impact your life due to their damage. For example,winds can damage houses, trees, and any other property. Even if your home is safe, flooding aftermath can occur. When homes are destroyed, people may have to rebuild homes and towns.

Fossils in _______ layers of rock are generally estimated to be _______ than fossils found in the deeper layers. (3 points) Explain your answer for justification.
older, younger
newer, younger
older, older
newer, older
Answer:
newer, younger
Explanation:
this is the best answer
Answer:
Answer is option (C) older, older.
Explanation:
Fossils found in the older layers of a rock (i.e) that are deposited in a deeper position of the Earth, are usually older when compared with the fossils seen in the upper layers of the rock.
Due to the fact that the fossils get accumulated layer upon layer, the older fossils are seen in the bottom layers of the rock.
How does diversity in traits arise over generations? How can we determine the probability that an organism's expressed version of a trait will be passed on to its offspring?
Answer:
Diversity in traits arise over generations through mutation which cause evolution and speciation. We can determine the probability that an organism's expressed version of a trait will be passed onto its offspring through Hardy-Weinberg equilibrium. Hardy-Weinberg equilibrium helps us understand and know genotype and allele frequencies.
Through mutation, which leads to evolution and speciation, diversity in features develops over generations.
What is diversity?The variety of human distinctions that make up diversity includes, but is not limited to, racial or ethnic origin, gender, gender orientation, age, socioeconomic class, physical ability or traits, and political ideas.
Over generations, diversity in traits emerges through mutation, which causes evolution and speciation.
We can calculate the probability that an organism's expressed version of a trait will be passed on to its offspring using the Hardy-Weinberg equilibrium.
The Hardy-Weinberg equilibrium is used to explain genotype and allele frequencies.
Thus, this way, we can determine the probability that an organism's expressed version of a trait will be passed on to its offspring.

Pepsin, trypsin and chymotrypsin are substances that affect reaction rates, those can be defined as
Answer: Enzymes
Explanation:
Enzymes are those proteins which participate in a chemical reaction without being consumed in the reaction. These enzymes work as a catalyst which speed up the rate of the chemical reaction. The enzyme is responsible for converting the substrate into a product. Pepsin is an enzyme present in the stomach it is activated by hydrochloric acid it is a peptic enzyme which converts proteins into peptones, trypsin and chymotrypsin are the enzymes secreted by the pancreas and it is responsible for digestion of proteins.

why is global warming dangerous?
Answer:
Since the Industrial Revolution, the global annual temperature has increased in total by a little more than 1 degree Celsius, or about 2 degrees Fahrenheit. Between 1880—the year that accurate recordkeeping began—and 1980, it rose on average by 0.07 degrees Celsius (0.13 degrees Fahrenheit) every 10 years. Since 1981, however, the rate of increase has more than doubled: For the last 40 years, we’ve seen the global annual temperature rise by 0.18 degrees Celsius, or 0.32 degrees Fahrenheit, per decade.

How do changes to genes affect the traits of an organism
Changes to genes affect the traits of an organism, as genes have the capability to regulate the organism's function, and the genes can regulate the expression of proteins, which regulate the organism's phenotypic and genotypic expression.
What is the significance of the genes or the traits?Changes in the genes can affect humans in several ways, such as through genetic mutations that result in changes to the regulation of gene expression and result in the addition or loss of entire genes from the organism. Not all of the genetic mutations lead to expressiable changes, but they may change the protein sequence by changing the polypeptide sequence.
Hence, changes to genes affect the traits of an organism, as genes have the capability to regulate the organism's function, and the genes can regulate the expression of proteins, which regulate the organism's phenotypic and genotypic expression.

Your lungs take in air through the mouth and nose. Explain how the lungs function in the human body.
A) They coordinate the movement of the heart.
B) They pass oxygen from the air into the blood.
C) They pump the blood throughout the body.
D) They remove carbon dioxide from the air.
Answer:
Your answer would be "B) They pass oxygen from the air into the blood."
Explanation:
They certainly don't coordinate the movement of the heart, so A isn't an option.
The lungs also don't pump blood through the body, that's the hearts job.
And the lungs do not filter carbon out of the air, which eliminates D.
Therefore your answer is B.
The lungs function in the human body by passing oxygen from the air into the blood.
Gaseous exchange in the lungGaseous exchange happens in the lung of humans. Oxygen is exchanged for carbon dioxide.
A mixture of air is taken through the mouth and the nose into the lung. On getting to the lung, the oxygen in the air dissolves on the surface of the lung and enters the blood by diffusion.
In exchange, carbon dioxide in the blood diffuses in the opposite direction and is breathed out.
