Answer:
A planet is a celestial body that revolves around a star. In our solar system, Earth is the third planet from the sun. The word planet comes from the Greek planetes, which means "wanderer." Since ancient times, people have been fascinated by the wandering of celestial bodies in the night sky.
Explanation:
Della and Nick drove at constant
speed from town A to town B along
the same road. The distance between the
two towns was 210 km. Nick left
Town A half an hour later than Della
Both of them arrived in Town B at
the same time . Della drove at a
Speed of 60 km/h Find Nick's speed.
Plzz help mee
Answer:
70 km/hr
Explanation:
Distance between town A and B = 210 km
Della's speed = 60 km/hr
Time taken by Della = distance / speed
Time taken by Della = 210 km / 60km/ hr
Time taken by Della = 3.5 hours
Since Nick left half an hour later Than Della ;
Then, Nick's travel time = 3.5 - 0.5 = 3 hours
Nick's average speed = Distance /time
Nick's average speed = 210 / 3 = 70km/hr

Explain what is “bottleneck” and why genetic drift is more powerful in small populations.
Answer:
because more is being forced through
Explanation:
Answer:
A bottleneck in genetics is an event that kills off or isolates a large portion of the population.
Explanation:
The more individuals in a population, the greater the genetic diversity. A genetic bottleneck happens when the number of individuals in a population gets greatly reduced. This happens as a result of random chance. For example, a storm might come through and knock down a bunch of trees. Birds that live in the trees may get harmed and those that survive now have to find a new home, so they migrate to other areas leaving behind a small population. This is important because the fewer individuals there are, the less genetic diversity and therefore, the less ability of the population to adapt. If you have lots of different genes available and a new disease arises in the population, it's more likely that some individuals will survive. If you only have a few genes available, it is less likely any individuals will survive. This can lead to really quick adaptation and evolution of a species.

Explanation:
A rock contains a radioactive isotope that decays to half of its original
amount in 5 million years. When this rock formed, it was made up of 100%
of the radioactive isotope, and 0% of the new element that it decays
If you find this rock and analyze it, and find that it contains only 50% of the
radioactive isotope and 50% of the new element, how old must this rock
be? *
1) 2.5 millon years
2) 10 million years
3) 5 million years
4) 15 million years
Answer:
3) 5 million years
Explanation:
The rock is 5 million years old because the rock contains only 50% of the radioactive isotope. We know that this rock decays to become half in 5 million years. Initially, the rock has 100% of radioactive isotope and 0% of the new element that forms with the decaying of the rock. But 50% of the radioactive isotope decays and 50% of the new element is formed so we can say that it reaches to its half age which is 5 million years.
How does gravity affect objects of different mass close to Earth, and how does that effect
change as an object moves farther from Earth
Answer: Gravity is the universal force of attraction. ... This force of gravitational attraction is directly dependent upon the masses of both objects and inversely proportional to the square of the distance that separates their centers. This means that as you move away from an object the gravitational force decreases.
Explanation:
In this question we are going to answer two questions about the gravitational force that keeps us grounded.
How does gravity affect objects of different mass near Earth?The force of gravity between two objects is the product of their masses divided by the square of the distance between them. That is, the more mass an object has and the closer it is, the greater its force of attraction on another object.
How does it affect change as an object moves away from Earth?The gravitational force decreases, and the object begins to be attracted by other gravitational forces besides that of the earth.
With this information, we can conclude that the gravitational force of the earth keeps us attached to it, and as we move away from the earth we lose these forces of attraction.

How is the liver adapted to its regulatory functions
Answer:
The liver controls most chemical levels in the blood. It also secretes a clear yellow or orange fluid called bile. Bile helps to break down fats, preparing them for further digestion and absorption. All of the blood leaving the stomach and intestines passes through the liver.

6. How might protein synthesis execute differently if a mutation occurs?
Answer:
The wrong protein can be created or the right one with abnormal function.
Explanation:
The mutated DNA is taken through the whole protein synthesis process and translated by the rRNA and tRNA to create a protein from that new sequence.
1. There are two types of viral architectures, one is naked and the other is enveloped. Please answer the following questions. A. What are the essential structural components and their functions of a naked virus? B. What molecules can be founded on the viral envelop? Explain the sources of these molecules. C. Is naked or enveloped virus more sensitive to detergent and alcohol? Explain your reasons.
Answer:
Naked viruses do not have a phospholipid membrane.
Explanation:
Nonenveloped or naked viruses do not have a phospholipid membrane outside their capsid and remain naked to the external environment. The envelopes are consists of portions of the host cell membranes i.e. phospholipids and proteins as well as some viral glycoproteins are also present in the envelop. Enveloped virus is more sensitive to detergent and alcohol as compared to naked virus because the naked virus has resistance against environmental factors which is absent in the enveloped virus. Once the envelop removed or broken, the virus loses its functional receptors and is not able to cause infection to susceptible cells.

A large population of Yellow perch lives in the East river. The Walleye is a larger fish that eats the Yellow Perch. Despite lots of prey all the Walleye have moved from the East river to a new river. What most likely caused the Walleye to move to a different river?
(A)There is a lack of food in the East river which caused the Walleye to move to a different area.
(B) The Walleye are no longer able to catch the Yellow Perch and need to move to a different area.
(C)There is climate change which has caused the resources to decline in the East river.
(D) There is pollution in the East river that the Yellow Perch are adapted to but the Walleye are not.
Answer:
(D) There is pollution in the East river that the Yellow Perch are adapted to but the Walleye are not.
Explanation:
To ensure survival and cntinurd sustenance in an environment, there is need for an animal to posses certain features which would enable her cope with the conditions of the environment. The ability of animals to successfully live and survive in an environment is made possible through adaptation as the animal's adaptive features ensures the animal is able to live through and cope. If the adaptive features aren't suitable for such environment, then migration has to occurs, leading the animal to find a more suitable environment for survival. In the scenario above, the East river was presumed to be a good habitat for the Walleye and Yellow Perch, in spite of the available and abundance of food, the Walleye migrated, which is most likely due the fact that the Walleye lack the adaptive features to survive in the East river probably due to pollution which the Yellow Perch is well adapted to.
When the blood glucose level decreases during a fast or between meals, the pancreas releases glucagon. Glucagon signals the liver to stop consuming glucose and to start producing glucose. Select the statements that describe how glucagon activates glucose production in the liver.
Answer:
Glucagon signals the liver to start producing glucose.
Explanation:
Glucagon signals the liver to start producing glucose from the breakdown of amino acids through gluconeogenesis process. When the glucose level decreases in the body due to fasting or starvation, the pancreas release glucagon which provides signals to the liver to produce glucose form non carbohydrates substances present in our body. This production of glucose increases the concentration of glucose in the blood and the body used this glucose for the generation of energy molecules in the form of ATP.

What is the biggest difference between the geocentric model and the heliocentric model
Answer: The main difference is that the geocentric has the Earth at the center, and the heliocentric has the sun at the center. The geocentric model says that the earth is at the center of the cosmos or universe, and the planets, the sun and the moon, and the stars circles around it. The early heliocentric models consider the sun as the center, and the planets revolve around the sun.
