Drea is comparing three organisms. Two have many of the same characteristics. But they have very few characteristics in common with the third organism. What can Drea infer about the relatedness of these three organisms?
Group of answer choices
The first two are unrelated, but each is related to the third.
Relatedness of the three organisms depends on the characteristics the first two share.
The first two are more closely related to each other than they are to the third.
The first two are equally related to the third.
Answer:
The first two are more closely related to each other than they are to the third.
Explanation:
The question tells us that the first two organisms share many common characteristics with each other, this tells us that the first two are related. We can cross out answer choice a. The question also tells us that the first two have very few characteristics in common with the third organism. With this much info given, the answer choices left are:
Relatedness of the three organisms depends on the characteristics the first two share.The first two are more closely related to each other than they are to the third.The first two are equally related to the third.First choice doesn't make any sense, there is no correlation between the common characteristics of the first two with the 3 organisms as a group.
Second choice makes sense and logical.
Third choice is wrong since the question does not give us enough information to know the first two is equally related to the third.
The first two are more closely related to each other than they are to the third. Is the right answer.

What color is reflected back to cause plants to appear green?
Answer:
Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green.
Chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants.
Chlorophyll absorbs light most strongly in the blue portion of the electromagnetic spectrum, followed by the red portion. Conversely, it is a poor absorber of green and near-green portions of the spectrum, hence the green color of chlorophyll-containing tissues.
Explanation:
Have a great rest of your day
#TheWizzer
Because chlorophyll does not absorb the green wavelengths of white light, it is chlorophyll that gives plants their green color. Thus, the correct option is B.
What is Chlorophyll?Chlorophyll is a pigment that is found in all green plants as well as some other species. It is crucial for the process of photosynthesis, which transforms light energy into chemical energy.
The chlorophyll pigment is in charge of giving plants their characteristic green hue since it does not absorb the green portions of white light; as a result, the plant reflects the particular light wavelength, giving it the appearance of being green.
Since chlorophyll is a poor absorber of the green and near-green portions of the electromagnetic spectrum, tissues containing chlorophyll are green in color. Chlorophyll absorbs light most powerfully in the blue and red portions of the electromagnetic spectrum.
So, the correct option is B.

Different substances have different properties that can be used to identify them. There are three test tubes X, Y, and Z filled with gas.
Can the properties of the gas in each test tube be used to tell whether the gases are the same or different?
What do you think might happen when a gas is exposed to a small flame? List as many possible results as you can think of

Back
The properties of the gas in each test tube can be used to tell whether the gases are the same or different, because depending on the substance, chemical reactions will occur.
What do you think might happen when a gas is exposed to a small flame?This happens in the flame test, which is based on the fact that when a certain amount of energy is supplied to a certain chemical element (in the case of a flame, energy in the form of heat), some electrons in the last valence shell absorb this energy.
Moving to a higher energy level, producing what we call an excited state. When one of these excited electrons returns to the ground state, it releases the energy previously received in the form of radiation.
With this information, we can conclude that the properties of the gas in each test tube can be used to know if the gases are the same or different, because depending on the substance, chemical reactions will occur.

DNA typing is based on analyzing parts of the genome that don't really affect other genetic functions.
A. True
B. False
The question proposed is in fact false, given that the variations being analyzed do in fact affect the individual.
Why is this question false?DNA typing uses the detection of polymorphisms to identify an individual. These polymorphisms are variations in the genetic code that are considered to be normal. These variations are said to not be harmful nor beneficial but do in fact impact the rest of the genome in very subtle ways.
Therefore, we can confirm that the question proposed is in fact false, given that the variations being analyzed do in fact affect the individual.

what is one benefit to giant octopuses laying many eggs?
Answer:
The majority of baby octopuses born don't reach adult hood, laying more eggs increases the number of babies that have a chance to make it to adulthood.
Answer:
During courtship, both octopuses use their sense of sight to determine attraction. Males are looking for a large female. Larger diploid females produce more haploid eggs, by meiosis If more eggs are fertilized, it gives the male a greater probability to pass on his genes.
Explanation:
just allows males to pass on more of their traits

Energy pyramids show the most available energy at the base and the least amount of energy at the top. What accounts for the difference in the energy levels in these two parts of the energy pyramid?
choices:
A. Some of the energy is destroyed
B. The energy is used by decomposers
C. The energy is continually recycled in the biosphere
D. With each succeeding level, most of the energy is used by the organisms for life processes and some of the energy is "lost" as heat
Answer:
D
Explanation:
the energy from the sun is gradually lost after each level increase because the organism before being eaten uses the energy to stay alive such as staying warm or running from predators
A box is pushed a distance of 4 meters with a force of 10 N. How much work has been done?
6 units of work
40 units of work
14 units of work
No work has been done
The quantity of work done by the box is equal to 40 units of work.
Given the following data:
Distance = 4 meters.
Force = 10 Newton.
How to calculate work done.In Science, work done is generally calculated by multiplying force and the vertical distance (displacement) that is covered by an object.
Mathematically, work done is given by the formula:
Work done = force × distance
Substituting the given parameters into the formula, we have;
Work done = 10 × 4
Work done = 40 units of work.

The black bear has a tendency to proliferate, whereas the polar bear has a tendency to undergo faster extinction because they live in the arctic.
Dark bearsThe black bear (Ursus americanus), also known as the baribal, is a North American bear, found from Alaska to northern Mexico. It reaches 2.20 m in length, 1.10 m in height at the withers and 360 kg in weight.
Light bearsThe polar bear (Ursus maritimus) is a solitary mammal that lives in the icy waters of the Arctic Circle region. It is the largest species of bear that lives in places with low temperatures, being much feared by other animals that inhabit the place.
Considered the largest terrestrial carnivore and main symbol of arctic resistance, the polar bear has been suffering from climate change.
