Answer:
Zooplankton - Animals (mostly microscopic) which drift freely in the water column.
Explanation: Zooplankton, small floating or weakly swimming organisms that drift with water currents and, with phytoplankton, make up the planktonic food supply upon which almost all oceanic organisms are ultimately dependent.
Hope this helped!!
50 POINTS!! In the carbon cycle, all animals must consume other organisms because A. they can not absorb enough carbon from water. B. they cannot absorb carbon directly from the air. C. they are in competition with plants for available carbon. D. they require carbon to perform photosynthesis.
Answer:
C
Explanation: A fish can live in water and get carbon in the air bubbles but it's not enough carbon to thrive off of so the fish may need to eat other fish or plankton in the water. The second example A wolf would get its carbon from both the air and water but would still need extra carbons so that is why it would hunt a deer to consume its carbons. Also, the deer would get its carbons from the air, water, and grass. the grass would get its carbons from water and air. NOW DO YOU GET IT EVERYTHING IS CARBONS AND LIVES OFF OF THEM AND IT WILL ALWAYS BE THAT WAY!

Please answer.
Which applied force will cause a glass of water sitting on a countertop to move?
A. a balanced force
B. a frictional force
C. a gravitational force
D. An unbalanced force
Answer:
The correct answer is D. an unbalanced force.
Explanation:
If an unbalanced force were applied to the glass of water (for example, someone pushing the glass, lifting it up, etc.), this would cause it to move. However, a balanced force (if two people were to simultaneously pull the glass in opposite directions with the same amount of force) would not cause the glass to move. Gravitational force acts on all objects; the force due to gravity is already acting on the cup at rest and will not cause it to undergo motion. Friction is also already acting on the cup in the form of static friction, making it harder for someone to move the cup, so frictional force will not cause the cup to move either. Therefore, the correct answer is D. an unbalanced force.

I'm building a carbon atom. I've been told that the atomic number of carbon is 6, which means
that the carbon atom has protons.
Answer:
The carbon has 6 protons
Explanation:
The atomic number equals the quantity of protons and electrons in a neutral element.
Answer:
6 protons
Explanation:
The atomic number of an atom signifies the number of protons found in the the nucleus of the atom of a specific element.
It also represents the number of electrons, but only in an neutral or uncharged atom.
We are told the atomic number of carbon is 6. We also know that the atomic number is equal to the number of protons. Therefore, the carbon atoms has 6 protons.

Answer:
the rats weight loss
Explanation:
The dependent variable would the weight of the rats.
The dependent variable is the variable whose value is dependent on another variable during an experiment. It is the actual variable set out to be measured or tested by researchers. The effect of the manipulation of the independent variable is measured on the dependent variable.
Hence, in an experiment aimed at determining whether a new diet medication will help rats to lose weight, the weight loss by the rats would be the dependent variable.

How might you model the relationship between a tomato plant and the hornworm caterpillar?
Answer:
This model can be called a parasitic relationship
Explanation:
A parasitic relationship is a form of relationship/interaction between two organisms in which one organism (called parasite) lives at the expense of the other organism (called host); causing harm or death to the host.
A hornworm caterpillar feeds on the upper part of tomato plant leaves, causing harm to the plant in the process. Hence, the tomato plant is the host while the hornworm caterpillar is the parasite.
In an effort to control vegetation overgrowth, 108 rabbits are released in an isolated area free of predators. After 2 years, it is estimated that the rabbit population has increased to 972. Assuming exponential population growth, what will the population be after another 9 months
Answer:
246
Explanation:
Increased amount / current population = 972
Amount released = 108
time(t) = 2years
Using the exponential growth function :
f(t) = A*g^t
Where g = growth rate
To obtain the growth rate = g
972 = 108 * g^2
g^2 = 972 / 108
g^2 = 9
g = 3
To determine population after 9 months :
9 months to years = (9/12) = 0.75
t = 0.75
f(0.75) = 108*(3^0.75)
f(0.75) = 108 * 2.2795070
f(0.75) = 246.18676
= 246
Why do dominant traits tend to be seen more frequently in a population? A. There are more dominant alleles. B. Organisms only need one copy of dominant to exhibit the trait. C. Recessive traits show up more in populations.
Answer:
I think is c hope this help
Answer:
[tex]\boxed{Option \ A}[/tex]
Explanation:
Dominant traits tend to be seen more frequently in a population because there are more dominant alleles. If it seems like in a community that the dominant traits show up more then this means that the dominant alleles are more.
state the difference between osmosis and active transport
Answer:
Osmosis is movement of water molecules from an area of their higher concentration to area of their lower concentration through a semipermeable membrane.
Active transport is movement of molecules from an area of their lower concentration to area of their higher concentration using energy in form of ATP by pump proteins.
Explanation:
transport system is consider as the opposite to osmosis. Because you are going against the gradient, active transport requires a pump or carrier protein in the cell membrane and therefore energy (made through respiration).

Explanation:
A biology student wanted to determine if there is a relationship between resting heart rate and time spent exercising per week.
Answer:
YES, there is a relationship between resting heart rate and physical activity.
The higher the physical activity, the better the physical performance, the better the cardiac contractile quality, therefore the lower the heart rate at rest.
Explanation:
The heart is a muscle that is trained like the rest, when practicing physical activity it contracts and expels blood more often and more intensely.
Thus generating that the contractile power is more effective, that is to say that in each bombardment it ejects more blood into the aorta, therefore there will be less effort at rest.
This is how training generates hypertrophy of myocytes, they contract better, generate blood ejection to the vascular system in a more efficient contraction compared to sedentary, therefore the oxygenated volume will not have to be replaced immediately, thus generating the heart have to beat or eject more slowly.
By contracting fewer times per minute, we are faced with the phenomenon of decreased heart rate, this is measurable by taking the pulse of an athlete at rest and comparing it with a sedentary person also at rest.
Answer:
69 bpm
Explanation:
1.) There is an inverse trend seen in the graph. Students who do less exercise tend to have a higher resting heart rate, while students who do more exercise tend to have a lower resting heart rate.
2.) Using the line created by the data points, we can determine that students who exercise around 3 hours per week seem to have resting heart rates between 68-72 bpm.
3.) The correct answer is: 69 bpm
(01.01 HC) Birds belong to different species but share similar characteristics. What inference can be correctly drawn about this statement?
Answer:
The correct answer would be - All birds share a common ancestor.
Explanation:
All birds shows similar characteristics and traits even though they belong to different species. According to the various studies and research it is found that the reason behind this similarity in traits and characteristics due to the common ancestor.
Studies states that the all modern birds share the common ancestor that was found during some time of Late Cretaceous and evolved from that common ancestor.
Thus, the correct answer is : All birds share a common ancestor.

Comparing amino acid sequences in proteins has been used to determine the relatedness of organisms. Below is a graphic that shows the amino acid sequence differences between different organisms for a protein keratin. Changes in amino acid sequences are known to cause changes in structure of proteins. Species A Species B Species C Species D Species E Species A 4 11 19 1 Species B 12 18 5 Species C 8 10 Species D 20 Species E Part A. Consider species A, D, and E. Using the data provided, describe how the structures of their keratin proteins would compare. Part B. Keratin is made up of about 450 amino acids. Determine the similarity in percentages between species A and B, A and C, and B and C. Explain how amino acid sequences can be used in determining how closely related two species are. Part C. Based on this data, predict which two species would be more closely related to one another. Part D. Justify your predictions to part C.
Answer:
A) Species A and E are more closely related than either species are related to species D.
B) Between A and B = 99.1%
Between species A and C =97.5%
Between species B and C = 97.3%
Similarity in amino acids sequence reflects similarity in DNA sequence
C) Species A and E are most closely related
D) Species A and E have the most similarity in amino acid sequence, and hence DNA sequence.
Explanation:
A) The amino acid sequences of the protein, keratin, in species A and D has a difference of about 19 whereas species A and E have a difference of only 1. Therefore, it means that keratin in species A and D will have differences in structure whereas between species A and E, they would have almost the same structure.
Also, species D and E have a difference of 20 in their amino acids sequence, therefore, the structure of keratin in both species will have differences in structure.
B) Similarity between A and B:
450 - 4 = 446
In percentage: 446/450 × 100% = 99.1%
Similarity between A and C:
450 - 11 = 439
In percentage: 439/450 × 100% = 97.5%
Similarity between B and C:
450 -12 = 438
In percentage: 438/450 × 100% = 97.3%
The sequence of DNA of species determines their amino acid sequences because information in DNA is transcribed to RNA which are then used to make proteins. Therefore, if a species are very closely related, they are expected to have very similar genetic sequences and thus proteins too. This is reflected in similarity between amino acid sequences in their proteins.
C). Species A and E are most closely related.
D) Species A and E have only a single difference in their amino acids sequence for Keratin. This translates to about 99.7% similarity which is the highest among all the species compared. Therefore, species A and E are most closely related.
