B. Multicellular, eukaryotic, heterotrophic
C. Unicellular, eukaryotic, heterotrophic
D. Multicellular, eukaryotic, autotrophic

WHAT ARE ANIMALS:
Animals are organisms that belong to a kingdom called ANIMALIA. Animals are a group of organisms that possess the following characteristics as the basis of their classification:Heterotrophic: All animals are heterotrophic meaning that they cannot synthesize their own food, hence, they rely on other organisms for their energy source. Eukaryotic: All animals have a true membrane bound nucleus in their cells, hence, they are said to be EUKARYOTIC. Multicellular: All animals have more than one cell to carry out specific tasks in their body system.Hence, all animals are multicellular, eukaryotic, and heterotrophic.

A habitat that receives little or no precipitation will most likely be suitable for organisms that -
spend most of the day in the sunlight.
are covered in thick fur to keep warm.
store large quantities of water internally.
hibernate for long periods of time.
Sunlight is not always a requirement- but less water = more water that needs stored. Think - succulents, for example. Succulents live in mid - low shade and store water because they live in an environment with little precipitation.
What is Precipitation?Any liquid or frozen water that condenses in the atmosphere and falls to the ground is referred to as precipitation. Rain, sleet, and snow are only a few of its various manifestations.
Precipitation is one of the three main processes that make up the global water cycle, together with evaporation and condensation.
Water vapor in the clouds condenses into increasing-sized droplets of water, forming precipitation. The drips hit the ground when they are sufficiently hefty. The water droplets may freeze to produce ice if a cloud is colder, as it would be at higher elevations.
Therefore, Sunlight is not always a requirement- but less water = more water that needs stored. Think - succulents, for example. Succulents live in mid - low shade and store water because they live in an environment with little precipitation.

Below is a carrying capacity graph of a meerkat population in an African savanna. Meerkats are omnivores and eat a variety of organisms, such as fruit, insects, scorpions and lizards. Predators of the meerkat include hyenas and eagles. What is a possible cause for the sudden change in population of meerkats after year 3?
A. Warmer weather increased the number of insects.
B. The number of eagles was reduced due to disease.
C. A fire reduced the amount of grass and fruit available.
D.A lack of predators increased the lizard population.
A fire reduced the amount of grass and fruit available.
What is carrying capacity in ecology?
In ecology, carrying capacity is measured as the maximum load of an environment. The physical features present in the environment act as limiting factors (e.g. food, water, competition, etc.). Thus, the population limit can be expected to depend on these factors.
What is carrying capacity of an ecosystem?
Populations grow at a rate limited by the availability of the Earth’s resources. A population may grow at a faster rate and follow a J-shaped curve. When the birth rate surpasses the death rate of the species, this results in exponential growth.

a) the mass of the car and the height of the inclined plane b) the friction of the surface of the inclined plane and the mass of the car c) the length of the inclined plane and the time for the car to descend the inclined planed) the length of the car and the time for the car to descend the inclined plane
Helpppppppppp!!!!!
Answer:
c) the length of the inclined plane and the time for the car to descend the inclined plane.
Explanation:
The information that is needed to calculate speed is the length of the inclined plane and the time for the car to descend the inclined plane. Thus, the correct option for this question is C.
How speed is defined?Speed is defined as the rate of change of position of an object in any direction. It is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.
If you want to calculate the speed of the car, you must definitely be required to determine the length of the inclined plane through which it is running along with the time for the car to descend the inclined plane. There are some necessary quantities that are required prior to determining the actual values in the same or different contexts.
Therefore, the correct option for this question is C.

The diagram below shows a simple version of the carbon cycle... How are the processes shown with yellow arrows different from the processes shown with red arrows? *
The yellow arrows are all caused by human activities.
The yellow arrows are all completely natural processes.
The yellow arrows all add to the greenhouse effect.
The yellow arrows all take carbon out of the atmosphere.
Answer:
b. The yellow arrows are all completely natural processes.
In the given carbon cycle, the yellow arrows are all caused by human activities. The correct option is A.
What is carbon cycle?The carbon cycle is nature's way of recycling carbon atoms, which commute onto from atmosphere into lifeforms on Earth and then again into the environment.
The maximum amount of carbon is stored in rocks and sediments, with the left over in the ocean, atmosphere, and living organisms.
The carbon cycle describes how carbon moves between various 'carbon reservoirs' on Earth.
It is critical for our planet's climate and carbon balance to remain stable. Carbon is the backbone of the Earth, and the carbon cycle regulates it naturally. The Earth would be frozen if it didn't have it.
In the given chart, the decomposition, fossil fuels, etc. all are done through humans, hence the yellow arrows are indicating man made activities.
Thus, the correct option is A.

There was the same amount of variation in spot size 40 years ago and last year.
There was more variation 40 years ago.
There was more variation last year.

Answer:
there was more variation last year
Explanation:
so here's my thinking- 40 years ago the guppies' spot size ranged from 5-10 and last year they ranged from 3-9 seeing as how 10-5 is 5 and 9-3 is 6 and how 6>5 there was more variation last year compared to 40 years ago.
