Why do cells have a high surface area to volume ratio? *
A. to contain more nutrients
B. to contain more organelles
C. to more readily exchange substances across the cell.
D. to have only small substances travel across the cell.

Answers

Answer: C

Explanation: Smaller single-celled organisms have a high surface area to volume ratio, which allows them to rely on oxygen and material diffusing into the cell (and wastes diffusing out) in order to survive. The higher the surface area to volume ratio they have, the more effective this process can be.

If two trucks have the same mass, but truck A is traveling 15 km/h, and truck B is traveling 30 km/h, what statement is true? Question 2 options: Truck A has greater kinetic energy. Truck B has less kinetic energy. Truck B will have a greater stopping distance. Truck A will have a greater stopping distance.

Answers

Given that the two trucks have the same mass but different velocities, that is truck A is traveling 15 km/h and truck B is traveling 30 km/h,  hence  Truck B will have a greater stopping distance.

The reason why Truck B will have a greater stopping distance is because it speed is greater hence more distance to cover.

From the following expression

Speed = Distance/Time

Distance = Speed*Time

More on the kinetic Energy

Following from the given problem truck B will also have more kinetic energy because it velocity is more

Formula

KE= 1/2mv^2

Hence the more the velocity for a constant mass the greater the Kinetic energy

Which statement best explains why the population stabilized and why?!

A population of chipmunks migrated to an environment
where they had little competition, Their population quickly
increased but eventually stabilized as shown in the graph.

A. Interbreeding between members of the population increased the mutation rate.

B. A predator species came to the area and occupied the same niche as the
chipmunks

C.
The population size became limited due to factors such as availability of food.

D. An increase in the chipmunk population caused an increase in the producer
population.

Answers

Answer: C. The population size became limited due to factors such as availability of food.

Explanation:

Out of all the choices, C is the most likely to happen since more often then not, food runs out because a species has too many members. C is an example of the environment’s carrying capacity limiting the chipmunk species.

Since we are not told if the chipmunk population is really small, interbreeding may not happen. Predators hunt prey, not eat fruits like chipmunks do (I’m assuming what chipmunks eat.) If there was a predator species that came in, they would hunt the chipmunks instead of competing for the same resources. D just doesn’t make much sense in my opinion because that wouldn’t limit the chipmunk population.

The population size became limited due to factors such as availability of food in the chipmunks. Thus the correct option is C.

Why the population size become limited?

The population size become limited because of carrying capacity. It can be defined as a species' average population size in a particular habitat.

The chipmunks species population size is limited by environmental factors like adequate food, water, shelter, and mates. If these needs are not met, the population will decrease until the resource resile.

Describe how scientists make inferences on whether water is polluted or not

Answers

Answer: Water that's safe to drink should ideally be clear with no odor or funny taste. One way to tell if water is contaminated is to look for turbidity, or cloudiness. While cloudy water isn't necessarily dangerous to your health, it could signal the presence of unsafe pathogens or chemicals.

Explanation:

Drinkable water should ideally be transparent and taste and smell normal. Look for turbidity, or cloudiness, as one indicator that water is contaminated.

What is drinkable water?

Surface water and groundwater are the two sources of potable water, also referred to as drinking water. The level of treatment applied to this water satisfies both state and federal standards for potable water.

The indirect potable reuse (IPR) and direct potable reuse (DPR) processes are the two basic ways to turn wastewater into potable water (DPR).

Foggy water may not always be harmful to your health, it may indicate the presence of germs or chemicals that are toxic.

Therefore, Drinkable water should ideally be transparent and taste and smell normal. Look for turbidity, or cloudiness, as one indicator that water is contaminated.

which belongs on the y-axis? Explain your reasoning.

Answers

Answer:So, the temperature depends on the time. So, the temperature is dependent, and the time is independent. If you're looking at a graph, the independent variable is generally on the horizontal axis

Explanation:

As a result, the temperature changes with time. Therefore, while the time is independent, the temperature is dependent. The independent variable is often on the horizontal axis when viewing a graph. So the independent variable is on the x-axis and the dependent variable is on the y-axis..

What are variables?

Any attribute that can have varying values, such as height, age, temperature, or test results, is referred to be a variable in research. To assess the causality of links, researchers frequently modify or quantify independent and dependent variables in studies.

The cause is the independent variable. Its value is unaffected by other research factors.The effect is the dependent variable. Changes in the independent variable affect its value.

Explanation:

Animal: All components present. Plant: All components present. Virus: Only cell membrane present. Prokaryote: Cell membrane present, others absent.

Option (1) is correct.

Animal: Cell membrane, ribosomes, lysosomes, and nuclear membrane are present. Animals are eukaryotic organisms with membrane-bound organelles and a well-defined nucleus.

Plant: Cell membrane, ribosomes, lysosomes, and nuclear membrane are present. Plants are also eukaryotic organisms and share similar cellular structures with animals, including membrane-bound organelles and a nucleus.

Virus: Only a cell membrane may be present, depending on the type of virus. Viruses are acellular particles that lack organelles and a nucleus. They consist of genetic material (DNA or RNA) enclosed in a protein coat called a capsid. Some viruses also have an outer lipid envelope derived from the host cell's membrane.

Prokaryote: Cell membrane is present, but ribosomes, lysosomes, and nuclear membrane are absent. Prokaryotes, such as bacteria, lack a nucleus and membrane-bound organelles. They have a simpler cell structure, with genetic material located in the cytoplasm and ribosomes involved in protein synthesis. Lysosomes, which are membrane-bound organelles involved in digestion, are not present in prokaryotes.
