Answer:
They produce sugars in order to survive and grow. Animals eat plants and take advantage of the nutrients produced by the plants. They also breathe in the oxygen produced as a by-product of photosynthesis
Explanation:
Plants use the energy in sunlight, water, and carbon dioxide to produce sugars which are used to provide chemical energy to power cellular processes. These sugars are also stored as starches.
Animals cannot produce their own food, and instead, rely on plants and other animals as a food source to power their own processes. Animals eat plants and obtain the food that plants have produced by photosynthesis. This is mostly carbohydrates (sugars and starch) but also some fats, proteins, and vitamins.

Describe two pathways the student can use to show how a metamorphic rock
could become another type of rock and then become metamorphic once again
Answer:
In order for a metamorphic rock to become a sedimentary rock, the rock must undergo erosion. Once the rock has eroded, it will produce rock fragments or sediments which accumulate to form a sedimentary rock. ... In turn, when igneous and sedimentary rocks are exposed to heat and pressure, the rocks become metamorphic.
Explanation:
hope this helps
Answer:
One pathway is that an igneous rock can apply heat and pressure to the rock which will become metamorphic. Another pathway is that a metamorphic rock can be changed by heat and pressure to form into a different metamorphic rock.

What is true about Structure A
please answer if not then that’s fineee
Answer:
✔️Facilitated diffusion does not require any of cell energy.
Explanation:
The above structure A is known as Cell Membrane. It is a permeable membrane through which materials are diffused or transported in and out of the cell.
Option A is true for structure A because facilitated diffusion does not require the cell's energy. Facilitated diffusion is passive transport of molecules or ions across the membrane which is spontaneous.
It is passive because facilitated diffusion does not directly require chemical energy from ATP hydrolysis. What happen is that molecules and ions move down their concentration gradient. This movement reflects their diffusive nature.
In the rock cycle, what happens to the magma and lava once they cool and harden?
Answer:
For magma to become sediment, it would first cool and harden and become igneous rock. Weathering and erosion would expose the igneous rock and break it into sediments.

Fill in the Punnett square below to visualize the offspring of a cystic fibrosis carrier and a person who doesn't have cystic fibrosis and isn't a carrier. Use F to denote the normal allele and f to denote the mutated CFR allele. What percentage of their children are likely to have cystic fibrosis? What percentage of their children are likely to be carriers of cystic fibrosis?
Answer:
50% of their children are likely to be carriers of cystic fibrosis
Explanation:
Since the normal allele "F" will be the dominant allele while the mutated CFR allele "f" will be the recessive allele, the gene (pair of alleles) of the person that is a CFR carrier will be "Ff" while that of the normal person who isn't a carrier will be "FF". The attachment shows the crossing between the two parents. From the illustration in the attachment, for every 4 children given birth to, 2 of them will likely be normal, "FF", (not a carrier and doesn't have cystic fibrosis) while 2 others will likely be carriers of cystic fibrosis (Ff). Hence, 50% of their children are likely to be carriers of cystic fibrosis.
