Why do most angiosperms have alternate phyllotaxy, with leaf emergence at an angle of 137.5° compared to leaves above and below?

Elanso [62]

Answer: The answer is D: to allow maximum exposure to light and to reduce shading of lower leaves.

Explanation:

The arrangement of leaves on a Stem is known as Phyllotaxy. It is used to enable them obtain maximum exposure to sunlight.

Leaves are classified as either alternate, spiral or opposite.

Leaves with alternate pattern arise at a different point (node) on the stem. This helps reduce shading of the lower leaves.

In the last stage of cellular respiration, oxidative phosphorylation, all of the reduced electron carriers produced in the previ

Mumz [18]

Explanation:

ADP, O2, NADH

Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’s cycle via the oxidization of pyruvate( through the process of glycolysis).

Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration. The process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria this forms a gradient where there is a differential in the number of protons on either side of the membrane the protons re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the ET see molecules of oxygen accept electrons and protons form molecules of water.

If A Plant Cell Were A House...

Cytoplasm

Vacuole

The Cytoplasm

would be the carpeting. The Cytoplasm is the goo that all the organelles reside in, and all the furniture and stuff in the house kind of sit there in the carpeting.

The vacuole would

be the closets and pantries. The vacuole holds random things that the cell needs, and closets and pantries can hold anything you feel like putting in them, like food or clothes.

Lysosome

Mitochondrion

The mitochondrion would be the kitchen. It produces energy for the cell to use, and the kitchen produces food, energy for humans.

Nucleus

Endoplasmic Reticulum

Rough

The nucleus would be my mom. The nucleus controls the cell, and my mom controls my house.

Ribosomes

The Smooth ER would be just plain hallways. The ER is a vast network of tubing that things the cell needs travel down.

The Rough ER would be hallways filled with cattle. This wouldn't be a very good example, because it isn't a very vast network. A lot of people travel down them, though! The Rough ER is like smooth, except with ribosomes.

If you had a herd of cattle in your yard, it would be them. If not, just the kitchen, like the Mitochondrion. Ribosomes synthesize proteins, and cattle make milk, which is full of protein. Also, in the kitchen you can make proteins with different types of dairy, like cheese or milk.

Smooth

Lysosome

Golgi (apparatus)

The Lysosome would be the trashcans, the recycle, and the compost. The Lysosome kills bacteria and holds it in plus other waste, and we dispose of our waste by putting it in one of the above options.

The Golgi (apparatus) would be my dad. The Golgi sorts and packages macromolecules to get them ready to transport. My dad does the same sort of thing, he's in charge of kind of organizing/sorting things around the house.

Cell Membrane

The Cell Membrane would be

the doors and the screens (on the windows). The cell membrane is a semi-permeable barrier, meaning that some things can get through and some can't. For example, only people who have the right key can open the door. Also, with the screens, air can get in, but flies and bees can't.

Chloroplast

Cell Wall

The Chloroplasts would be solar panels, if you had any, or houseplants if not. The Chloroplasts convert sunlight into energy, and both houseplants and solar panels do this same job.

If a cell were a house,

the walls, floors, and ceiling would be the cell wall because they keep everything in the house inside, just like the cell wall keeps all the organelles inside the cell.

How do organic compounds differ from inorganic compounds?

Dennis_Churaev [7]

All the organic compound differs from inorganic compound by carbon composition.

Answer: Option A

<u>Explanation:</u>

An organic compound is a compound which is composed of one carbon particles binded with different components. Most generally, these carbon molecules are clung to hydrogen, oxygen and nitrogen particles. On the other hand, an inorganic compound is not basically made out of carbon molecules.

There can be either carbon atoms present or missing. Thus it can be inferred that the presence and absence of carbon determines whether a compound is inorganic or organic.
