Based on Kepler's observations about planetary motion, what is the relationship between a planet's orbital velocity and its distance from the sun?
Answer is the greater the distance, the slower the orbital velocity..
I do not understand it. Can someone please explain it to me? Thank you!
Answers
Answer:
Explanation:
The closer the planet is to the sun,the faster it moves because the suns gravitational pull is stronger.The answer tells you that the greater the distance,the slower the planet will rotate
Kepler laws of planetary motion can be stated as planets move around the sun in elliptical orbits, the radi joins the planets to sun leaves out equal areas to equal intervals in the equal lengths of time.
The planets that are farther away from the sun have slow velocity and longer paths such as pluto. These factors make it longer for one complete revolution.Thus greater will be the distance the slower will be the velocity of movement such as that of mercury and pluto. As sun gravitational pull will be weaker.Learn more about the Kepler's observations about planetary motion.

1. Over time, the climate of an island became drier, which resulted in changes to the populations of various island finch species. Finch populations with a certain beak shape thrived, while those not having that beak shape decreased, Which of the following describes a necessary condition for thesechanges in the finch populations to occur?
Answers
Answer:
A necessary condition for the changes in the finch populations to occur in response to the drier climate would be:
- Variation in beak shape within the initial population: There must have been existing genetic variation in the population of finches regarding beak shape. Some finches would have had the beak shape that provided an advantage in obtaining food resources in the drier climate, while others would have had different beak shapes.
Without this initial variation in beak shape, there would be no opportunity for natural selection to act and favor individuals with the advantageous beak shape. Therefore, the presence of genetic variation within the population is necessary for the changes in the finch populations to occur.
Based on the theory of natural selection, the necessary condition for the changes in the finch populations to occur is limited food resources. Option B
What does natural selection say?Natural selection is the process by which populations of living organisms adapt and change over time.
Natural selection occurs when there is variation within a population of a species, and some individuals are better able to survive and reproduce than others.
These individuals are more likely to pass on their genes to the next generation, and the population will gradually change over time.
The above answer is based on the full question below;

Scientists discover two populations of mice on either side of a
major river. The two populations have almost identical genes, but
the mice from one side cannot breed with the mice from the other.
This is most likely because
Select one:
O both species of mice lived on both sides but owls killed one population on each side.
O the river separated one species of mice into two different species.
O the similar habitat caused two species to become genetically
similar
O two different species of mice migrated to the river from different
directions
Answers
Answer:
The river separated one species of mice into two different species.
Explanation:
A physical barrier, like a river, divides a population of a species into two different populations, which is a scenario that is most likely an example of allopatric speciation. The two populations may eventually diverge genetically, ecologically, or behaviorally, and they may also stop being able to reproduce with one another and give birth to healthy offspring. The two populations split into two distinct species as a result of their seclusion.
It's important to note that while two species' shared environment led to their genetic similarity, the fundamental cause of their speciation is the physical barrier that divides them.

During the paper test, solution 2 left a faint stain behind and was determined to be milk while solution 4 left a very definite and greasy stain
behind and was determined to be oil. What can be concluded about the lipid content of milk?
Multiple Choice
It contains a higher concentration of lipids than oil
It contains a lower concentration of lipids than oil.
It contains no lipids
It contains the same concentration of lipids as oil
Answers
Explanation:
Lipids produce grease on paper because they cannot evaporate easily at room temperature. So, the “intensity” or definition of a greasy stain left behind by a substance can be a good indicator of its lipid content.
Solution 4, the oil, left a “definite greasy stain”, so it can be discerned that it has a considerable lipid content. However, solution 2, the milk, left only “a faint stain” behind.
If solution 2 had a lipid content equal to or higher than solution 4, it would have left a greasy stain that was identical or even more defined than the one left by the oil. If it had no lipid content, no stain would have been left behind.
So, it must have some lipids, but not an equal or higher concentration of lipids than that of the oil.
Then, the correct response must be that solution 2, the milk, contains a lower lipid content than solution 4, the oil.

Both mitosis and meiosis begin with a diploid cell that contains replicated chromosomes. What are the main differences between these two processes, and what types of daughter cells produced by each?
Answers
Answer:
Hope this helps :)
Explanation:
Mitosis is the process by which cells duplicate.
Meiosis is a similar process which is just used to make reproductive cells such as eggs or sperm.
In mitosis, the cell DNA arranges into 46 chromosomes, duplicates, and then divides into two new cells.
In meiosis, the same duplication occurrs except four cells are created, each with only 23 chromosomes. (You know how you get half of them from each parent? This is so that the offspring have genetic variation.)
Another thing to notice about meiosis is that the cells are not identical like in mitosis, which simply duplicates them. Furthermore, in males all four sex cells are used as sperm but in females only one of these cells develops into an egg whereas the rest, called polar bodies, are reabsorbed into the body.
Answer:
Meiosis has two cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has one cell division and results in two identical daughter cells.

The traits of a living organism are the result of complex interactions of chemical components that make up the living organism. Proteins do much of the chemical work inside cells, so they largely determine an organism’s traits. What components are responsible for providing the genetic code that determines how proteins are built and, therefore, how they determine traits?
Answers
The components responsible for providing the genetic code that determines how proteins are built and, therefore, they determine traits are the nitrogen bases of nucleotides in the DNA molecule.
What are the nitrogen bases of nucleotides in the DNA molecule?Nitrogen bases of nucleotides in the DNA molecule are small subunits of these building blocks of the genetic material. In DNA, a nucleotide is composed of three different subunits which are the nitrogen bases, the sugar ribose and a phosphate group.
There are four types of nitrogen bases which are called adenine or A, guanine or G, cytosine or C, and thymine of T.
Therefore, with this data, we can see that nitrogen bases of nucleotides in the DNA molecule are four (A, C, G and T) and they are building blocks of the nucleotides that form the genetic material of an organism cell.
