what is a plate boundary
Answer:
Plate boundaries are the edges where two plates meet. Most geologic activities, including volcanoes, earthquakes, and mountain building, take place at plate boundaries. ... Divergent plate boundaries: the two plates move away from each other. Convergent plate boundaries: the two plates move towards each other.

Is hydrogen the right answer y’all?
Answer:
The correct answer is hydrogen.
Explanation:
Stars in the main sequence will remain in the main sequence as long as their cores contain hydrogen atoms. This is because main sequence stars run on the hydrogen atoms within their core to prevent them from falling to the force of gravity. Once these hydrogen atoms run out, the star is no longer considered a main sequence star, gravity takes hold, and the star collapses.

Question 4
Calculate the nlass of 7.1 x 1024 formula units of magnesium hydroxide, Mg(OH),.
its me again this is how you find the answer. note: i dont have the periodic table to see the exact atomic mass to find the molar mass however this is the answer:
so the actual formula is Mg(OH) with a 2 as a subscript because there are 2 Mg. so with Mg(OH)2 the Molar mass is 58.32g/mol. 58.32 g/mol x 7.1x1024 = 4.1x1026g

Our digestive enzymes are able to break the alpha linkage in potatoes but not the ?? Linkage in paper
Answer:Beta
Explanation:
I watched the video and I got it wrong, the right answer was beta. I can’t explain why because I’ve already forgotten lol
Digestive tract have digestive enzymes which are not able to break beta linkages as humans do not have enzymes which breakdown beta linkages.
What is digestive tract?
It consists of the gastrointestinal tract along with the accessory organs which are present in digestion process . It involves the breakdown of complex food into smaller components which can be easily assimilated and absorbed by the body.
The digestion process has 3 phases: cephalic phase , gastric phase and intestinal phase.Cephalic phase begins with secretion of gastric juices from gastric glands in response to sight and smell of food.It involves chewing and chemical breakdown of food by the action of digestive enzymes ,saliva in the mouth contain enzymes like lipase and amylase which are secreted by the salivary and serous glands present on the tongue.

Can someone help with question 6 ASAP
Answer:
A metalloid is a type of chemical element which has a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals. There is no standard definition of a metalloid and no complete agreement on which elements are metalloids. Despite the lack of specificity, the term remains in use in the literature of chemistry.
A series of six elements called the metalloids separate the metals from the nonmetals in the periodic table. The metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium. These elements look metallic; however, they do not conduct electricity as well as metals so they are semiconductors. They are semiconductors because their electrons are more tightly bound to their nuclei than are those of metallic conductors. Their chemical behavior falls between that of metals and nonmetals. For example, the pure metalloids form covalent crystals like the nonmetals, but like the metals, they generally do not form monatomic anions. This intermediate behavior is in part due to their intermediate electronegativity values. In this section, we will briefly discuss the chemical behavior of metalloids and deal with two of these elements—boron and silicon—in more detail.

How many energy conversions occur when both acetyl-CoA molecules go through the kerbs cycle
A. 5
B. 6
C. 10
D. 12
Answer:
i dont even know tbh jk i wont waste ur time unless nvm ok so the answer is The correct answer would be C.10. Krebs cycle is a part of cellular respiration that takes place in the mitochondria. Five energy conversions take place in one complete cycle of the Krebs cycle. These conversions lead to the formation of three molecules of NADH, one molecule of FADH₂ and one molecule of ATP.

Mole Conversion: How many molecules are there in 6.70 moles of methane, CH4
Answer:
Explanation:
1 mol of methane = 6.02 * 10^23 molecules
6.70 mol of methane = x
Cross multiply
x = 6.70 * 6.02 * 10^23
x = 4.033 * 10^23 molecules.

Put an aluminum atom, Al (aluminum) and an aluminum ion, Al^3+ in increasing (smallest to greatest) order. (Enter "Al" or "Al^3+" first, then enter a semicolon, then enter one space and then enter "Al" or "Al^3+" second.) 4 points
Answer:
Al^3+;Al
Explanation:
When a metal ion is formed, the corresponding ion is smaller than the atom from which it was formed.
Oftentimes, the formation of a metal ion leads to the loss of an entire shell. The reduces the ionic radius compared to the atomic radius. Hence the metal ion is always much smaller than the metal atom.
