it's function is to regulate the growth in human body

if it produces lots of hormone then the body will increase a lot in size known as gigantism

if it produces very less hormone then the body will not increase in size and will be very short known as dwarfism

(III)thyroid gland-it secretes thyroxin

its function is to maintain metabolism growth

lack of iodine makes this gland swell up known as goitre.

(iv)Adrenal gland - it secrets adrenaline

Four of the six kingdoms are compromised of organisms that contain
eukaryotic cells. Which structure in a cell would give you the BEST
evidence that the cell is eukaryotic? *
O Ribosome
O Genetic material
O
Nucleus
O Cell membrane

Answers

Answer:

The best evidence that a cell is eukaryotic is the presence of the cell structure called the nucleus.

Explanation:

The most significant difference between eukaryotic and prokaryotic cells is that the former have a nucleus, where they store genetic information in the form of DNA.

The nucleus of eukaryotic cells occupies approximately the center of the cell and is a structure associated with the endomembrane system. Its function is to control cell activity, and its genetic material is duplicated before cell division.

In prokaryotic cells, in the absence of a nucleus, the genetic material is dispersed in the cellular cytoplasm.

Regarding the other options:

    Both cell types, eukaryotes and prokaryotes, have ribosomes, genetic material and cell membrane.

Answers

Answer:

c.

Explanation:

Because youcaring electrons from photosystem II, to photosystem I, to NADP+

I took this test about it hope that helps :D

The role of the electron transport chain in the process of photosynthesis will be carrying electrons from photosystem 1, to photosystem to NADP. The correct option is C.

What is electron transport chain?

An electron transport chain is a collection of protein complexes and certain other compounds that donate electrons from electron donors to electron acceptors via redox reactions and couple this electron transfer with the transfer of protons across a membrane.

Photosystems I and II are protein complexes found in the thylakoid membrane.

Their function is to capture high energy electrons from chlorophyll and pass them on to a series of electron carriers before splitting water to form oxygen and hydrogen ions and producing NADPH.

Electron transport contributes to the formation of a proton gradient, which drives ATP production and also stores energy in the reduced coenzyme NADPH.

This energy is used to power the Calvin Cycle, which produces sugar and other carbohydrates.

Thus, the correct option is C.
