If you meant global warming the answer is that polar ice and icebergs meltdown and polar bears’ habitat gets smaller and smaller...

Which INCREASE gas exchange? (choose all correct) Group of answer choices: a) increased pressure gradient for carbon dioxide exc

zysi [14]

Answer: Increased pressure gradient

Explanation:

The movement of gas takes place by the help of diffusion. The pressure is established in between the two different types of gases.

The movement of gas from higher concentration to lower concentration will take place when a pressure gradient is established in between them.

So, if there is an increased pressure gradient between oxygen and carbon dioxide then gaseous exchange will take place.

What is a star like object that is very bright and distant

kow [346]

Quasar is a star like object that is very bright and distant.

Quasars are massive, bright, and most distant known celestial objects that release high amounts of energy in the form of electromagnetic radiation, which usually has a star-like image in a telescope. Quasars can only be found in galaxies that have super-massive black holes (black holes that have billions of times of solar masses). In quasars, the black holes are enclosed by a gaseous accretion disk.

The duct that connects the pancreas to the duodenum can sometimes become blocked. what is the result?

stiv31 [10]

The duct gland is comparable to the dimensions and form of a little banana, and is gift within the higher abdomen, towards the rear, nearer to the spinal chord. Whereas,the duct gland is solid containing evacuation tubes. The duct gland juices area unit created within the acinar tissues, and gone by secretion into the ducts for transport into the small intestine. The exit hole into the small intestine is named the papilla of Vater.

The biliary juices are created within the tissues of the liver, then pass into the biliary ductal system. Sort of a stream, these ducts bit by bit be a part of it along to create one stream within the main epithelial duct, that exits into the small intestine at the "papilla of Vater."

3 Li 6.941 how can i draw this?

Mashutka [201]

6.941 tells you the nucleon number (total number of protons and neutrons in the nucleus of an atom)
3 tells you the proton number( number of protons in the nucleus of an atom.)
When drawing this you must know the number of protons , electrons, and neutrons of that element. Well in this question, everything’s been given. No. of protons = 3
No. Of electrons = 3 *REMEMBER, NUMBER OF PROTONS AND ELECTRONS ARE EQUAL WHEN THE ELEMENT IS IN ITS ATOMIC FORM.
No. Of neutrons= 4 neutrons. When rounding 6.941, it is 7. Then simply subtract 7-3 to get 4.
Now time to draw this. First you must know the number of electron shells does lithium has. Since lithium is in period 2, it has 2 electron shells.
Then, you must know what is the valence electron of Li. It is 1, since it is a group I element/alkali metal.
Also remember the structure. Electron are surrounding the nucleus of the atom on electron shells while the nucleus is in the center of the atom. Nucleus contains the protons and neutrons. REMEMBER THE FIRST SHELL SHOULD CONTAIN ONLY 2 ELECTRONS WHILE THE SECOND SHELL WITH 8 ELECTRONS AND GO ON.
Hope this helps and if I’m correct can you add me to the brainliest?
