An object with a mass of 20 kg and potential energy of 584 J is what distance above the ground
Answer:
29.2 m
Explanation:
P=mh. Plug in the values.
584 J = 20 kg x h
h = 29.2 m
If it's gravitational potential energy multiply is by gravity which I think is 10 m/s.

Explanation:
defenition of osmosis in your own words
Answer:
Osmosis is the scientific process of transferring fluid between molecules. When molecules move in and out of a cell to achieve the same concentration of something, like salt, on both sides, then osmosis is happening. ... The fluid might go back and forth a few times until both solutions are equally concentrated.
Answer:
Movement if water molecules from the region of higher concentration to the region of lower concentration, down a concentration gradient, through a partially permeable membrane, till it reaches equilibrium state.

Answer:
Yes?
Explanation:
I don't exactly understand the question but yes the carbon dioxide (co2) you breathe out is used by plants where they break it into carbon and oxygen, release the oxygen for us to breathe, and us the carbon to create glucose and ATP.

What type of tissue comprises wood in woody stems?
Answer: Woody plants have an extra layer of protection on top of the epidermis made of cork cells known as bark. The vascular tissue of the stem consists of the complex tissues xylem and phloem which carry water and nutrients up and down the length of the stem and are arranged in distinct strands called vascular bundles.
Explanation:
Bark protects woody plants' epidermis with cork cells. Xylem makes up most of a stem's wood, while phloem is in the bark.
What makes up most of a woody stem?Many shrubs and plants have woody stems. The most notable distinction between the two kinds of stems is that woody stems are mostly made of firm cork rather than soft epidermis. As the cork ages, it develops bark and hard woods.
The inner and outer derivative products of the vascular cambium are secondary xylem (wood) and phloem. The primary constituents of xylem are dead cells with thicker cell walls rich in cellulose, hemicelluloses, and lignin. Xylem serves as the plant's mechanical support system and conductor of water and minerals.

during action potential, positively charged ________ ions move inside the cell.
Sodium ions move inside the side during action potential.
This stage of action potential is called depolarization.This open voltage gated sodium channel.What is action potential?
- Action potentials (those electrical impulses that send signals around body) are nothing more than a temporary shift (from negative to positive) in the neuron's membrane potential caused by ions suddenly flowing in and out of the neuron.
- It consists of phases:
depolarization overshootrepolarization.- An action potential propagates along the cell membrane of an axon until it reaches the terminal button.

All producers and autotrophs go through photosynthesis?
False ?
True ?
Because autotrophs produce their own food, they are sometimes called producers. ... Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose.
Why do muscles work in pairs
Answer:they only pull in one direction
Explanation:
Answer
Skeletal muscles only pull in one direction. For this reason they always come in pairs. When one muscle in a pair contracts, to bend a joint for example, its counterpart then contracts and pulls in the opposite direction to straighten the joint out again.

Explain your stepwise procedure for building the protein from DNA sequence
Answer:
During transcription, the enzyme RNA polymerase (green) uses DNA as a template to produce a pre-mRNA transcript (pink). The pre-mRNA is processed to form a mature mRNA molecule that can be translated to build the protein molecule (polypeptide) encoded by the original gene.

in total, how many molecules of nadh and fadh2 are produced during the oxidative metabolism of one molecule of glucose?
Answer:
Ten molecules of NADH, and two molecules of FADH2
Explanation:
Most of the usable energy obtained from the breakdown of carbohydrates or fats is derived by oxidative phosphorylation, which takes place within mitochondria. For example, the breakdown of glucose by glycolysis and the citric acid cycle yields a total of four molecules of ATP, ten molecules of NADH, and two molecules of FADH2. Electrons from NADH and FADH2 are then transferred to molecular oxygen, coupled to the formation of an additional 32 to 34 ATP molecules by oxidative phosphorylation. Electron transport and oxidative phosphorylation are critical activities of protein complexes in the inner mitochondrial membrane, which ultimately serve as the major source of cellular energy.
