Appetite can decrease with age, but going too long without eating causes metabolism to slow down. Current research shows that incorporating legumes such as lentils and chickpeas into meals boosts metabolism for twenty-four hours. Who might benefit from this claim?
A.people who have a fast metabolism
B.stores that sell exercise equipment

tony ate 3/4 of the pizza. mike ate 7/16 of the pizza. how much more did tony eat than mike
Answer:
5/16
Explanation:
make them have a common denominator
3/4 needs to be times by 4
so it's
12/16 then you minus 7/16
the answer is
5/16
Answer: 5/16
Explanation:
Multiply tonys 3/4 by 4 in order to get the same denominator as mike's 7/16. You should get 12/16 since 4x3=12, and now you can subtract the smaller fraction 7/16 from the bigger one 12/16, you should get a difference of 5/16.

Explanation:
How do scientists determine the number of neutrons in an isotope of an atom? O They find the number of protons. 0 They add the number of electrons and protons. They divide the atomic mass by two. They subtract the atomic number from the atomic mass.
Answer:
The three naturally-occurring isotopes of hydrogen. The fact that each isotope has one proton makes them all variants of hydrogen: the identity of the isotope is given by the number of protons and neutrons. From left to right, the isotopes are protium (1H) with zero neutrons, deuterium (2H) with one neutron, and tritium (3H) with two neutrons.
The term isotope is formed from the Greek roots isos (ἴσος "equal") and topos (τόπος "place"), meaning "the same place"; thus, the meaning behind the name is that different isotopes of a single element occupy the same position on the periodic table.[2] It was coined by a Scottish doctor and writer Margaret Todd in 1913 in a suggestion to chemist Frederick Soddy.
The number of protons within the atom's nucleus is called atomic number and is equal to the number of electrons in the neutral (non-ionized) atom. Each atomic number identifies a specific element, but not the isotope; an atom of a given element may have a wide range in its number of neutrons. The number of nucleons (both protons and neutrons) in the nucleus is the atom's mass number, and each isotope of a given element has a different mass number.
For example, carbon-12, carbon-13, and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13, and 14, respectively. The atomic number of carbon is 6, which means that every carbon atom has 6 protons, so that the neutron numbers of these isotopes are 6, 7, and 8 respectively.
Scientist at the CDC (Center for Disease Control) in Atlanta, GA are currently developing and testing new treatments and vaccines for the coronavirus. What kind of research are they conducting?
Answer:
Applied research
Explanation:
The process of developing a new vaccine involves the use of known scientific theories to address specific problems. Here, the outcome of several basic research are put into use to arrive at a targeted outcome. This outcome/product can be continuously modified (if it shows early promise) until the desired effect is achieved and if no "promise" is discovered at critical points of this research, work on this theory (for this research) is suspended another theory is pursued.
This process (described above) in which scientists continuously develop new treatments and/or vaccines and continuously subject it to testing until the desired effect is achieved can be referred to as Applied research.

This element has three fewer protons than oganesson 
Answer:
ununpentium
Explanation: this is element 115, Oganesson has 118
The atomic number of oganesson is 118. The element which is having three fewer protons than oganesson is moscovium (Mc) (115).
What is oganesson?
Oganesson is a newly found element synthesized in 2002 and is placed as 118'th element in the periodic table. In modern periodic table, the elements are arranged based on their atomic number.
Atomic number is the number of protons in the atom as well it is the number of electrons in the neutral atom. For a neutral atom the number of electrons are protons are equal.
Thus in a neutral atom the positive charges are neutralized by equal number of negative charges.
Thus, for 118'th element, there are 118 protons, three fewer from this means, there are 115 protons, the 115'th element in the modern periodic table is moscovium.

google takes its name from a conversion prefix. What is it and how big is it
Answer:
Giga, 1x10⁹.
Explanation:
Hello,
In this case, if we chew over Google's name, we can see that it suggests the word Giga which in conversion units context accounts for the Giga prefix (G) which has a value of 1x10⁹.
For instance 1 meter in gigameters is:
[tex]1m*\frac{1Gm}{1x10^9m}=1x10^{-9}Gm[/tex]
Which suggests that it is a huge unit and it makes sense considering the raft of information Google handles.

How is crystallization used in the pharmaceutical industry (simple answer please)
Answer:
CRYSTALLIZATION :IMPORTANT IN THE PHARMACEUTICAL INDUSTRY.IT IS A SEPARATION PROCESS FOR INTERMEDIATE AND A FINAL STEP IN PHARMACEUTICAL INGREDIENTS.A BRAINLIEST PLEEAAAASEWhat increases acidity more, nitrile group or chloride group?
Answer:
The nitrile group
Explanation:
The nitrile group contains the C≡N bond. It should be recalled that triple bond is highly electronegative and withdraws electrons from the C-H bond more effectively than the halogen atom.
The higher effectiveness of the C≡N bond at electron withdrawal greatly reduces the electron density of the C-H bond thereby making the hydrogen atom of the bond highly labile

What is the volume of a 200 gram sample of gold if its density is known to be 20.5 g/mL?
Answer:
The answer is 9.76 mLExplanation:
The volume of a substance when given the density and mass can be found by using the formula
[tex]volume = \frac{mass}{density} \\ [/tex]
From the question
mass of gold = 200 g
density = 20.5 g/mL
It's volume is
[tex]volume = \frac{200}{20.5} \\ = 9.7560975609...[/tex]
We have the final answer as
9.76 mLHope this helps you
