Answer: studies indicate that humans living in warm, tropical environments (from a variety of populations) tend to have noses that are wider at the base because inhaling warm, moist air does not require adaptations.

The calcium present in the milk acts as a fertilizer, for the growth of pumpkin size.

Explanation:

Scientific answer: Milk contains nutrients, minerals mainly calcium which are good for the growth of the plant as a fertilizer.

Milk gets readily absorbed by the roots due to the solubility of nutrients in milk.

The root hairs of the plant transport the calcium to the other parts like stem.

This will only help when all other factors of plant growth are present as sunlight, water other than fertilizer.

Non-scientific question:

The Hypothesis here is those pumpkin plant fed with milk are bigger on size.

Also injecting stems with milk would cause no good.

Pumpkin plants fed with milk and some plants fed with water are compared, we get the result that giant pumpkins are one that are fed with milk. This is  statistical analysis.

Temperatura: Las temperaturas más altas aumentan la energía y por lo tanto el movimiento de las moléculas, aumentando la velocidad de difusión.

After light hits photosystem I, its energy is used to produce what molecule
Jlenok [28]

Answer:

The correct answer is NADPH.

Photo-system I absorbs maximum photons at the wavelength of 700 nm.

It uses this energy to transfer the electron (received from photo-system II) to NADP⁺ to reduce it to NADPH.

Once, the reaction centre of PS I or P₇₀₀ gets excited, it transfer the high energy electron to the ferrodoxin (Fd) via cluster of iron and sulphur protein (4Fe-4S).

Reduced ferrodoxin then transfer the electron to NADP⁺ to reduce it to NADPH with the help of flavoprotein (ferrodoxin-NADP⁺ reductase).

NADPH is then used in Calvin cycle or light-independent phase of the photosynthesis in order to fix carbon to produce sugar or food.
