Answers

B) animals are multicellular, have eukaryotic cells and heterotrophic things take in air and make carbon so it’s the only one that has all animal stuff

Animals are organisms that possess the following characteristics: multicellular, eukaryotic, heterotrophic.

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.

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.

Helpppppppppp!!!!!

Answers

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.

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.

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.

HELP PLEASE!! i need help on A and B. PLEASE DONT ANSWER IF YOU DONT KNOW!! Please help me will give brainlyest Memories of a MemoryHave you ever witnessed something amazing, shocking or surprising and found when describing the event that your story seems to change the more you tell it? Have you ever experienced a time when you couldn't really describe something you saw in a way that others could understand? If so, you may understand why some experts think eyewitness testimony is unreliable as evidence in scientific inquiries and trials. New insights into human memory suggest human memories are really a mixture of many non-factual things.First, memory is vague. Imagine your room at home or a classroom you see every day. Most likely, you could describe the room very generally. You could name the color of the walls, the floors, the decorations. But the image you describe will never be as specific or detailed as if you were looking at the actual room. Memory tends to save a blurry image of what we have seen rather than specific details. So when a witness tries to identify someone, her brain may recall that the person was tall, but not be able to say how tall when faced with several tall people. There are lots of different kinds of "tall."Second, memory uses general knowledge to fill in gaps. Our brains reconstruct events and scenes when we remember something. To do this, our brains use other memories and other stories when there are gaps. For example, one day at a library you go to quite frequently, you witness an argument between a library patron and one of the librarians. Later, when telling a friend about the event, your brain may remember a familiar librarian behind the desk rather than the actual participant simply because it is recreating a familiar scene. In effect, your brain is combining memories to help you tell the story.Third, your memory changes over time. It also changes the more you retell the story. Documented cases have shown eyewitnesses adding detail to testimony that could not have been known at the time of the event. Research has also shown that the more a witness's account is told, the less accurate it is. You may have noticed this yourself. The next time you are retelling a story, notice what you add, or what your brain wants to add, to the account. You may also notice that you drop certain details from previous tellings of the story.With individual memories all jumbled up with each other, it is hard to believe we ever know anything to be true. Did you really break your mother's favorite vase when you were three? Was that really your father throwing rocks into the river with you when you were seven?
