A group of plant eating animals moves far away from their original population. In the new environment, the only edible vegetation grows at the top of tall trees. In order to survive, the animals need a new adaptation. Which of the following variations would be the most useful new adaptation to members of the group?
A) Wider, flatter teeth that can chew and grind plant material.
B) A longer neck to reach the vegetation that is high up in the trees.
C) A better digestive system for breaking down plant material.
D) Larger ears and eyes located on sides of head to detect predators.
Answer:
B
Explanation:
The others would not help because the animals could not reach the vegetation.
define magnification and cisternae?
Answer:
Magnification In general terms, it can be said that how big or small the image appears with respect to the object is called magnification of the object.
Explanation:
It is represented as the ratio of the height of the image to the ratio of the height of the object. Magnification is denoted as the letter 'm'.
Magnification is the process of enlarging the apparent size, not physical size, of something. This enlargement is quantified by a calculated number also called "magnification".
A cisterna refers to a flattened membrane disk that makes up the Golgi apparatus. A typical Golgi has multiple stacks of anywhere from 3 to 7 cisternae stacked upon each other like dinner plates.The cisternae also carry structural proteins important for their maintenance as flattened membranes and their stacking upon each other.

What are magnetic field lines?
A. Lines that show the shape of a
magnetic field
B. Lines that show the path of electrons
C. Lines that show aligned atoms
Answer:
A
Explanation:
Magnetic field lines are a visual tool used to represent magnetic fields. They describe the direction of the magnetic force on a north monopole at any given position. The density of the lines indicates the magnitude of the field.

45. If we put ANY type of cell in pure water: a) is pure water considered hypotonic, hypertonic or isotonic? b) would the cell shrivel or swell? c) what would happen to its turgor pressure (water pressure inside cell): increase or decrease?
Answer:
Explanation:
Pure water is an hypotonic solution that allows for diffusion of water into the cell and the cell will begin to swell.
The movement of water into the cell will make the cell swell but if water is moving outside the cell will collapse and shrink.
The turgor pressure is usually found withing the cell it ensures the movement of solutes when water is taken into the cell, the turgor pressure will increase. When water is taken out of the cell, the pressure will reduce.
How does a bird develop?
Answer:
All birds start their lives inside an egg. When some birds hatch from the egg they are covered in downy feathers, and they are able to run around and find their own food. Many ground-living birds, such as pheasants and ducks, develop in this way.
Cognition is studied indirectly. Please select the best answer from the choices provided T F
The statement "Cognition is studied indirectly" is true.
What is cognition?The mental action or process of obtaining psychological features and apprehension through self-satisfaction, experience, and the senses is the definition of cognition.
Cognitive psychologists are interested in the investigation of mental functions. This relates to the study of cognition, memory, learning, and problem-solving processes in people. Cognitive psychologists are interested in how people think or react psychologically to various situations.
On the other side, behavioral psychologists are interested in researching and observing behavior. It is additional research on the interactions between stimulants and outcomes.
Therefore, the statement is true about cognition.

Which of the following is one of the chemical building blocks of cells? a. water c. air b. food d. carbohydrates
Answer:
d. carbohydrates.
Explanation:
Sugar-consisting molecules. As a source of energy and energy storage cells employ carbs. The carbohydrates in the cells of an organism are broken down to release the stored energy.
Simple carbohydrates
Composed of one or a few molecules of sugar. Examples of simple carbs are table sugar and fruit sugar.
Complex Carbohydrates
Extra sugar from an organism may be preserved as complex hydrates of carbon. They consist of hundreds of molecules of sugar.
Explain how mitosis maintains the chromosome number
of the original cells when forming new cells.
Relation between mitosis and chromosomes:
During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Because this process is so critical, the steps of mitosis are carefully controlled by certain genes. As they move, they pull the one copy of each chromosome with them to opposite poles of the cell. When mitosis is not regulated correctly, health problems such as cancer can result.When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes.

define any three types of chromosomes depending upon position of centromere?
Answer:
The type of chromosomes based on the position of centromere are of the following four types :
1) Metacentric chromosome: centromere in middle forming two equal arms.
2) Sub-metacentric chromosome: centromere placed near to one end resulting in one shorter and one long arm.
3) Acrocentric chromosome: Centromere placed close to one end forming one extreme short and one extreme long arm.
4) Telocentric chromosome: terminally placed centromere.

If I wanted to prepare to run a marathon, what type of macromolecule would I want
to consume?
Answer:
Complex Carbohydrates
Explanation:
There are different types of macromolecules and they all have different purposes, but for a marathon carbs, specifically, complex ones would be best. This is because carbs are the main source of energy for the body. Additionally, unlike proteins, they allow for long-term energy; so you could run an entire marathon without running out of energy.

what is population ?A discrete accumulation identifiable characteristics such as people, animals with the objective of analysis and data collection is called a population.
A population consists of a same group of species who reside in a particular geographical place with their reproductive capacity to interbreed.
In a population Not all individuals are able to survive and reproduce due to genetic variations in them, a local population is restricted to a smaller area or can occupy a larger area, making up for the entire species.

Explanation:
An archer shot a 0.06 kg arrow at a target the arrow accelerated at 5,000 m/s squared to reach a speed of 50.0 m/s as it is left the bow.During this acceleration what was the net force to the nearest newton?
Answer:
the net force to the nearest newton is 300 N
Explanation:
The computation of the net force to the nearest newton is shown below:
According to the newton second law of motion, the force is proportional directly to the change rate in momentum
So,
Resulted force = mass × acceleration
F = 0.06 kg × 5,000 m/s
= 300 N
Hence, the net force to the nearest newton is 300 N
Answer:
300 N

Sea otters regulate the presence of the sea urchins and thus, kelp is regulated for all organisms in the ecosystem. They help to keep enough kelp for other wildlife to feed on. Also, due to their ability to absorb carbon dioxide, the kelp aid in mitigating climatic change and also reduce erosion by reducing the speed of water at the coast.However, if there were too many sea urchins and no sea otter to regulate their production, the kelp would reduce and thus with no food in the ecosystem, it would collapse. As a result, the sea otter protects the kelp forests by checking the local sea urchin population. The sea otter is an example of a
Answer:
keystone species
Explanation:
The sea otter is an example of a keystone species in the scenario.
A keystone species is an organism that has a significant influence on the functioning of the entire ecosystem. Without this species, the ecosystem would either cease to exist in total or entirely different in structure. In other words, a keystone species is a fastener that holds the ecosystem together.
In this case, the sea otter indirectly regulates kelp for all organisms in the ecosystem by directly regulating the presence of sea urchins. Without kelps, several ecosystem functions such as climate change mitigation and erosion reduction would cease. Thus, the sea otter is playing a significant role as a keystone species.
