Answer:
sharks
Explanation:
Because they are the ones to get the last bit of energy. Secondary consumers are the group in the food chain that eats primary consumers. This means that secondary consumers can either be omnivores or carnivores. These terms refer to whether or not they eat just meat or a varied diet. Secondary consumers don't need to have a specific diet.
The energy pyramid is a representation of the producers and consumers along with the flow of energy. The sharks will be at the top of the energy pyramid. Thus, option C is correct.
What is an energy pyramid?An energy pyramid is a graphical representation of the biomass of the producers and the consumers of the ecosystem. It consists of the trophic levels that have designated producers, primary consumers, and secondary consumers.
A producer is at the bottom of any energy pyramid as they produce the foods for the primary consumers that are most likely herbivores. The secondary or the tertiary consumers are at the top.
Therefore, option C. sharks being secondary consumers are at the top of the pyramid.

The endosymbiotic theory states that the mitochondria of eukaryotes are the evolutionary result of a Proto-eukaryotic cell engulfing an aerobic bacterium, which then evolved into the mitochondrion. Which characteristic of mitochondria supports this theory of development? A retention of a single layer membrane B retention of the chlorophyll pigments C retention of their own genome D retention of their own nucleus
Answer:
The correct answer is - C. retention of their own genome.
Explanation:
The endosymbiotic theory is a theory that suggests that eukaryotic cells are developed from prokaryotic cells. According to this theory, organelles like mitochondria are developed in eukaryotic cells as the result of proteo-bacteria cells engulfing aerobic bacteria.
The evidence of this theory can be seen as the mitochondria has their own genome such as circular DNA and ribosomes as the prokaryotes.

What did you include in your response? Check all that apply. Distance and displacement are the same in the 100-m sprint. Velocity and speed are the same in the 100-m sprint. Distance is 400 meters in the 400-m sprint. Displacement is zero in the 400-m sprint. Velocity is zero in the 400-m spri
Answer:
Distance and displacement are the same in the 100-m sprint, therefore, velocity and speed are the same in the 100-m sprint.
Distance is 400 meters in the 400-m sprint, therefore Speed is not zero in the 400 M sprint.
Displacement is zero in the 400-m sprint, therefore, Velocity is zero in the 400-m sprint
Note: The question is missing some details which is given below;
A 100-meter sprint is a race using only the straight side of a racetrack. a 400-meter sprint is a race that makes one complete lap around a racetrack. why are velocity and speed the same for a 100-m sprint but not a 400-m sprint?
Explanation:
The speed of a body is the ratio of the distance covered and the time taken whereas the velocity of a body is the rate of change of displacement with time.
Distance measures the total length of space covered throughout the duration of motion, whereas displacement measures the change in a specified direction from a specific point.
In the 100 m race along a straight line, both distance and displacement = 100 m, therefore speed and velocity are the same. However, in the 400 m race, distance covered is 400 m, but the displacement is zero since the person returns to his/her starting point. Therefore, speed is not equal to zero, but velocity is equal to zero.

How can a bacterium ensure that there is always a concentration gradient that will drive passive transport of food molecules into its cell?
Answer:
There are two major ways that molecules can be moved across a membrane, and ... is trying to be evenly distributed everywhere, like dropping food coloring in water. ... These channels are almost always specific for either a certain molecule or a ... When a molecule moves down its concentration gradient is it participating.
When a solute particle from the region of high concentration travels towards the region containing the lower solute particle is called passive transport. It is transported easily without spending energy.
Bacteria ensures that the food molecule from the surrounding will transport through the passive transport system by the concentration gradient as molecules can get in the cell by two processes.
Concentration gradient allows the movement of food from the region of high concentration towards the region of low concentration that is in the bacterial cells.
Bacterial membrane permits the movement of food molecules across its membrane easily.
Therefore food is transported to the bacteria through passive transport.

Provide at least three reasons why friction is needed.
Answer:
Although you normally hear about trying to reduce or eliminate friction, it actually has some important uses.
Since friction is a resistance force that slows down or prevents motion, it is necessary in many applications where you might want to hold items or do things and prevent slipping or sliding. In those cases, there is an advantage of having friction.
Quite often uses of frction can be seen from how things would be without friction. Without friction, you would not be able to walk, drive a car, or hold objects. Pens and pencils would not work.
Explanation:
Answer:
Friction allows people and objects to move. It provides traction for an object to start moving or change direction. It can also give people a better grip on objects. Finally, friction keeps objects in place when they are set down.

Base your answer to the question on the information below and on your knowledge of biology.
A biology student was given three unlabeled jars of pond water from the same source, each containing a different type of mobile unicellular organism: euglena, ameba, and
paramecium. The only information the student has is that the ameba and paramecium are both heterotrophs and the euglena can be either heterotrophic or autotrophic, depending
on its environment
State one way the euglena's two methods of nutrition provide a survival advantage the other unicellular organisms do not have.
No
Answer:
They can perform photosynthesis.
Explanation:
Autotrophs are organisms that can produce their own food, and heterotrophs are organisms that feed on other organisms. This means that the ameba and paramecium can eat only other microorganisms.
The euglena is not limited to this. Hypothetically speaking, if there were no other microorganisms around it (which is unlikely), the euglena would not die as long as it is exposed to sunlight. Thanks to chloroplasts, organelles that contain chlorophyll, it can perform photosynthesis - a process in which, with the help of sunlight, carbon dioxide, minerals, and water are used to synthesize food.

You notice that a group of students went on a hiking trip to Cockscomb basin. They are asked to climb a hill, by the time they reach the top of the hill some of them are almost out of breath, while others don't even make it to the top of the hill. Only a few seem not to be affected much by the climb. Plan and design an experiment in which you offer a possible explanation for the differences in breathing rate.
Answer:
It depends on the stamina of the individual.
Explanation:
The possible explanation for the differences in breathing rate is related to the daily activities of the individuals. For example, if the daily activities of the people are hard so it has big stamina and experience no difficulty in the climbing of a hill while those people who has little hard daily activities have low stamina and their breathing rates increases while climbing a hill. Where as those people who perform no daily activities have no stamina and will be unable to climb on the hill.
