The circulatory system is responsible for which of the following?
I. bringing oxygen to your cells
II. bringing nutrients to your cells
III. bringing carbon dioxide to your cells
I only
I and III only
I and II only
I, II, and III
EXPLAIN
Answer:
I, II
Explanation:
The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

Are there any steps of the rock cycle that do NOT connect directly to one another? Explain why this may be the case using at least two examples.
please helpp
Answer:
rocks are destroyed
explanation
ricks are never destroyed they descompose
There are no steps in the rock cycle that do not connect directly to one another. The rock cycle describes the continuous process by which rocks are formed, weathered, eroded, transported, deposited, and lithified, leading to the formation of new rocks.
What are the steps in rock cycle ?Each step of the rock cycle is interconnected and depends on the other steps. For example, the formation of sedimentary rocks requires the weathering and erosion of preexisting rocks, the transportation and deposition of the resulting sediments, and the lithification of the sediments into rock.
Without the weathering and erosion of preexisting rocks, there would be no sediment to form sedimentary rocks.
Similarly, the formation of metamorphic rocks requires the heat and pressure of burial and tectonic activity, which in turn is influenced by the existing rock formations and geological processes of the area.
Another example is the formation of igneous rocks, which can occur through the melting and solidification of preexisting rocks, or through volcanic activity.

When water evaporates, what happens to the molecules that make up the liquid water?

Answer:
Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor.

Explanation:
Alice went camping with her family. She set up her tent in a grassy area. After two weeks, she noticed that the grass under her tent turned brown. Which factor most likely explains why the grass turned brown?
lack of water and sunlight
lack of oxygen and fertilizer
lack of soil and shade
lack of food and nutrients
Water and sunlight are necessary for photosynthesis to occur absence of these turned the grass brown.
What is photosynthesis?It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.
The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.
