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.

Explain the relationship between the variation in estradiol and progesterone rates in the female body and the events that occur in the uterus during the menstrual cycle
Answers
Answer:
The ruptured follicle closes after releasing the egg and forms a corpus luteum, which produces progesterone. During most of this phase, the estrogen level is high. Progesterone and estrogen cause the lining of the uterus to thicken more, to prepare for possible fertilization.
Progesterone and estrogen are necessary to prepare the uterus for menstruation, and their release is triggered by the hypothalamus. Once you reach puberty, the ovaries release a single egg each month (the ovaries typically alternate releasing an egg)—this is called ovulation.

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.
Answers
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.

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.
Answers
Your answer is C- Store large quantities of water internally
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.

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.

Describe the steps of the rock cycle and relate them to weathering, erosion, plate tectonics, and mountain building
Answers
Answer:
The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Each rock type is altered when it is forced out of its equilibrium conditions. For example, an igneous rock such as basalt may break down and dissolve when exposed to the atmosphere, or melt as it is subducted under a continent. Due to the driving forces of the rock cycle, plate tectonics and the water cycle, rocks do not remain in equilibrium and change as they encounter new environments. The rock cycle explains how the three rock types are related to each other, and how processes change from one type to another over time. This cyclical aspect makes rock change a geologic cycle and, on planets containing life, a biogeochemical cycle.
Explanation:
The Rock cycle is the geological concept, in which transitions between sedimentary, metamorphic, and igneous rocks over geologic time occurs. The transitions between rocks occur due to weathering, metamorphism, erosion, and sedimentation.
The steps involved in the rock cycle are:
Weathering refers to the breakdown or dissolving of the rocks on the Earth's surface. After the weathering, the process of erosion occurs in which rock particles and minerals are transported via plants, animals, wind, and water. The igneous rocks are formed by plate tectonics. The heat from the mantle fuels the plate tectonics, which converts the igneous and sedimentary rocks into metamorphic rocks. Mountain building is caused by the intense deformation of layered rocks and the activity of metamorphic and igneous rocks in the orogenic stage.
Thus, the rock cycle is involved in various processes and transitions among different types of rocks that occur in the rock cycle.
