Answer:
Mucles work via two ways, Contraction and relaxation. Example, contracting your bicep and relaxing your tricep bends your arm. They work this way by connecting to bones, and when they contract or relax it pulls the bone with it. Example, contracting your quads pulls the bone on one side and tightens it against your joint, straightening it like pulling a rubber band tight makes it go straight

What is the relationship between a planet's distance from the sun and the length of its year?
A. The closer the planet is to the sun, the longer its year.
B. The farther the planet is from the sun, the longer its year.
C. A year on each inner planet is the same length; it is shorter than a year on an outer planet.
D. A year on each outer planet is the same length; it is shorter than a year on an inner planet.
Answer: It should be B) The farther the planet is from the sun, the longer its year.
Explanation:
The further away from the Sun it is, the slower the planet's orbital speed and the longer its path.
Hope this helps! :)
The slower the planet's orbital speed and the longer its journey, the farther it is from the Sun.It takes longer to complete an orbit due to both of those considerations, and a planet's year is longer.
What is the relationship between a planet's distance from the sun and the length of its year?
One astronomical unit separates the Earth from the Sun.The measured distance between planets and the Sun is less than one A.U., while the measured distance between an object and the Sun is larger than one A.U.A planet's diameter can be used to estimate its size. The ratio of the cubes of any two planets' average distances from the sun is equal to the ratio of the squares of their periods.The length of a planet's revolution will increase with its distance from the sun. The separations of the planets from the Sun follow a pattern in several ways.Mercury is 1.8 times farther away from the Sun than Venus, and Earth is around 1.4 times farther away than Venus.Earth and Mars are separated by 1.5 timesYears on planets that orbit the sun more closely than Earth are shorter.Years on planets that orbit the sun farther than Earth are longer.There are two basic causes for this.A planet's orbital distance is relatively brief if it is close to the Sun. Since the Sun's gravitational pull on a planet farther away is weaker, it not only travels a greater distance than a planet closest to it, but it also moves more slowly.Therefore, a planet takes longer to complete its orbit the larger it is. Neptune has the longest orbital period of any planet in the Solar System given its far from the Sun.As a result, Neptune has the longest year of any planet, lasting 164.8 years. As a result, the planet moves more quickly when it is closer to the Sun and less rapidly when it is farther away.As a planet travels around its orbit, its speed is continually changing.A planet moves most quickly when it is closest to the sun, and most slowly when it is further away (farthest). A planet moves more quickly when it is nearer the Sun because of the Sun's higher gravitational attraction.A planet moves more slowly in its orbit when it is farther from the sun because the sun's gravitational attraction is weaker at that distance.To learn more about planet's distance refer

The image shows the cone forecast map of a hurricane. Location P is marked in the upper right part of the map.
Which statement BEST describes the risk of damage due to the hurricane at P? URGENT
A) The risk is high as P lies near the border of the potential track area.
Eliminate
B) The risk is low as P lies where the hurricane is predicted to lose strength.
C) The risk is low as P lies far from the current center of the hurricane’s path.
D) The risk is high as P lies directly on the predicted center of the hurricane’s path.
The risk at location P depends on its proximity to the hurricane's predicted path and its intensity. If P is directly on the path or near the border, the risk is higher. However, if P is far from the center or in an area where the hurricane may weaken, the risk could be lower.
Explanation:The risk of damage due to the hurricane at location P can be best described by selecting the most appropriate statement from the given options. Considering that hurricanes develop over water warmer than 80 °F and intensify through the rapid rising of warm, humid air, which results in heavy rains and strong winds, the position of P in relation to the hurricane's track is crucial. If P lies near the border of the potential track area, it may still be at risk even if the hurricane loses some strength, as the size of hurricanes can lead to impacts well outside the center of the path.
Hurricanes have the potential to be dangerous due to a combination of high winds, heavy rainfall, and the potential for storm surges, all of which can cause extensive damage. The risk to P would therefore be higher if it lies directly on the predicted center of the hurricane's path where these factors are amplified. If P lies far from the current center or where the hurricane is predicted to lose strength, the risk may be lower, but it is important to note that hurricanes can be unpredictable and their paths can change.
C) The risk is low as P lies far from the current center of the hurricane’s path.
Based on the given information, the BEST statement to describe the risk of damage at location P on the cone forecast map of the hurricane is:
C) The risk is low as P lies far from the current center of the hurricane’s path.
The cone forecast map shows the potential track area of the hurricane. Location P is marked in the upper right part of the map, which means it is far from the current center of the hurricane's path. Since P is not within the cone or near the border of the potential track area, the risk of damage at P is low. This suggests that P is not likely to be directly impacted by the hurricane.

The hawaiian islands are in the middle of a large tectonic plate with many volcanoes. The volcanoes are direct result of the tectonic plate
The Hawaiian islands were formed due to a mantle "hot spot" that leads to volcanic activity. This hot spot remains mostly stationary as Earth's plates move, generating a chain of volcanic islands over time. Volcanoes, in general, demonstrate how the Earth advances its cooling process.
Explanation:The Hawaiian islands, located in the middle of a large tectonic plate, are a direct result of a phenomenon known as a mantle "hot spot." This is an area far from plate boundaries where heat rises from the interior of Earth. This hot spot beneath Hawaii currently keeps three active volcanoes heated. As Earth's plates move over time, the hot spot stays mostly in place, thereby leading to the creation of a chain of volcanic islands over millions of years. The tallest Hawaiian volcanoes are among the largest individual mountains on Earth.
Volcanic activity signals locations where lava rises to the surface, such as in the mid-ocean ridges or in regions where continental plates collide. This activity provides us with an opportunity to examine materials from deep within our planet. Ultimately, such volcanoes and the movement of tectonic plates demonstrate how Earth cools down, serving as an efficient heat transfer process from the interior to the space.

A multicellular organism generally includes a wide variety of cell types. Examples in vertebrates include blood cells, neurons (cells of the nervous system), and the cells that line the digestive tract. What is the role of DNA replication and gene expression in cell differentiation? A. Only the DNA that a cell will use is replicated, and all of the genes that it contains are always expressed. B. Only the DNA that a cell will use is replicated, and gene expression is tightly controlled. C. Nearly all DNA is replicated, and the omissions determine gene expression in the cell. D. All DNA is replicated, but gene expression varies widely among cells and over time.
Answer:
B.
Explanation:
When the needed DNA is replicated, the process which acts as on/ off switch to control when the specific proteins are made, and the volume of proteins needed to be made,( either to increase or decreases the volume of the protein ) is called Gene expression.
it mediates in the morphological changes which occurs in differentiation (specialization of cells to different tissues and organs) of cells during embryo growth and developments.
it is therefore a tightly control process which ensure expression of specific gene of the DNA as needed proteins.

how do people develops immunity?
Answer:
There are many different immunities innate, adaptive, and passive
Explanation:
I don't know which immunity you are talking about so i will explain all of them
We develop adaptive immunity when we're exposed to diseases or when we're immunized against them with vaccines.Innate immunity is when the skin acts as a barrier to block germs from entering the body. And the immune system recognizes when certain invaders are foreign and could be dangerous.Passive immunity: Passive immunity is "borrowed" from another source and it lasts for a short time. For example, antibodies in a mother's breast milk give a baby temporary immunity to diseases the mother has been exposed to.Hope this helpsHope this is rightBrainliest plzHave a wonderful dayDescribe the rules of probability and explain how they apply to genetics
1.) The Addition Rule: P(A or B) = P(A) + P(B) - P(A and B)
If A and B cannot occur together, then the third term is 0, and the rule reduces to P(A or B) = P(A) + P(B). For example, you can't flip a coin and have it come up both heads and tails on one toss.
2.) The Multiplication Rule: P(A and B) = P(A) * P(B|A) or P(B) * P(A|B)
If A and B are independent events, we can reduce the formula to P(A and B) = P(A) * P(B). The term independent refers to any event whose outcome is not affected by the outcome of another event. For instance, consider the second of two coin flips, which still has a .50 (50%) probability of landing heads, regardless of what came up on the first flip. What is the probability that, during the two coin flips, you come up with tails on the first flip and heads on the second flip.
Let's perform the calculations: P = P(tails) * P(heads) = (0.5) * (0.5) = 0.25
3.) The Complement Rule: P(not A) = 1 - P(A)
Do you see why the complement rule can also be thought of as the subtraction rule? This rule builds upon the mutually exclusive nature of P(A) and P(not A). These two events can never occur together, but one of them always has to occur. Therefore P(A) + P(not A) = 1. For example, if the weatherman says there is a 0.3 chance of rain tomorrow, let's see the chances of no rain.
P(no rain) = 1 - P(rain) = 1 - 0.3 = 0.7
The rules apply to genetics because they are used to reveal traits that are hidden in the genome by dominant alleles. Probability allows scientists and doctors to calculate the chance that offspring will inherit certain traits, including some genetic diseases.
Rules of probability -
Probability Rule One (For any event A, 0 ≤ P(A) ≤ 1)
Probability Rule Two (The sum of the probabilities of all possible outcomes is 1)
Probability Rule Three (The Complement Rule)
Probabilities Involving Multiple Events.
Probability Rule Four (Addition Rule for Disjoint Events)
Finding P(A and B) using Logic.
Explanation -
Probabilities predict the likelihood that certain events will occur such as the inheritance of a particular trait in an organism. ... It can also help to predict patterns of inheritance of traits and diseases in family lines.

How many years and centimeters of time passed before life appeared on Earth?
There are many postulates and assumptions of how and when life originated on Earth. It is said that life originated about 3.7 billion years ago as microbes and is said to form from nucleic acid molecules.
It is said that 8.1 billion years and 8.1 meters of time has passed before life originated on Earth.
Life originated from the most primitive type of cells called prokaryotes they were basic cells that lived in harsh climatic conditions of the early Earth environment.
They were just organic compound aggregates and lacked many membranes and systems. The thing that made them sustain was their replicating genetic material enclosed in phospholipids.
Therefore, 8.1 meters and 8.1 billion years ago of time has passed before the appearance of life on the Earth.

The equation shows a chemical reaction using 64 grams of calcium, 162 grams of zinc carbonate, and 152 grams of calcium carbonate
calcium + zinc carbonate -- calcium carbonate + zinc
According to the law of conservation of matter, how much zinc is present in the product?
a 64 grams
b 74 grams
c 88 grams
d 98 grams
According to the Law of Conservation of Matter, the total mass before and after a chemical reaction should be equal. In this case, this suggests there would be 226 grams of zinc in the product, which does not match any of the given answer choices.
Explanation:According to the Law of Conservation of Matter, the mass of the reactants (inputs to the reaction) should equal the mass of the products (outputs of the reaction) in a chemical reaction. In this case, the masses of calcium, zinc carbonate, and calcium carbonate add up to 378 grams.
In other words, 64 grams (Calcium) + 162 grams (Zinc Carbonate) + 152 grams (Calcium Carbonate) = 378 grams. This means the mass of the products should also be 378 grams.
The mass of calcium carbonate is known to be 152 grams. Therefore, by subtracting this from the total, we can determine the mass of zinc. 378 grams - 152 grams = 226 grams. So, the Law of Conservation of Matter suggests that there should be 226 grams of zinc in the product. However, since none of those options are available, we can suggest an error in the given options.

Make a statement that answers the question above
Thankyou!!!!!!!!!!!
Answer:
No I think that that the tongue has receptors for only certian tastes but, i also think that the tongue can also tatse smells. If you understand what i mean.
Explanation:
Answer:
The ability to taste sweet, salty, sour and bitter isn’t sectioned off to different parts of the tongue. The receptors that pick up these tastes are actually distributed all over. We’ve known this for a long time. And yet you probably saw the map in school when you learned about taste. So where did it come from? It is true that the tip and edges of the tongue are particularly sensitive to tastes, as these areas contain many tiny sensory organs called taste buds. It is true that the tip and edges of the tongue are particularly sensitive to tastes, as these areas contain many tiny sensory organs called taste buds. Indeed, results from a number of experiments indicate that all areas of the mouth containing taste buds – including several parts of the tongue, the soft palate (on the roof of your mouth) and the throat – are sensitive to all taste qualities.
You can pick the part of this that you really need.
