Answer:
chemical reactions
Explanation:
Chemical reactions like weathering can cause rock and earth movement, plants grow from rain which is weathering, snow is weathering and cold winters is freezing water. I don't see how flowing water can contribute to weathering because in rivers, creeks, etc, always flowing. So if flowing water is always moving, it's not caused by weathering.
I EDITED MY ANSWER:
Physical weathering is caused by purely mechanical changes to the rock, while chemical weathering is caused by chemical reactions. The answer is chemical reactions

Answer:
69%for the isotope that weighs 62.93 u and

You can approach this problem by using a single equation; let's say the first isotope contributes to the relative atomic mass by a fraction
x
(

Multiplying these fractions (0.69 and 1 - 0.69 = 0.31) by 100% percent to get the results as a percentage will give

Hello.
In this case, when chlorine gets ionized by gaining one electron it goes:
[tex]Cl^-[/tex]
Whose electron configuration is the same as argon:
[tex]Cl^-=Ar:1s^2,2s^2,2p^2,3s^2,3p^6[/tex]
Since the both of them have 18 electrons, they become isoelectric with the same neutral charge.

Which characteristic of life is described as the transfer of DNA from parent to offspring, and is important for keeping a species alive
A. Homeostasis
B. Cell Organization
C. Heredity
Answers
Answer:
C. Heredity
Explanation:
Homeostasis means that an organism can control its own body temperature. This is important because if we couldn't control our temperature, then our cells would have trouble working properly from being to hot or cold.
Cell organization means that our body and cells can organize themselves into groups that work together. For example, cells form groups and tissue for different organs while other cells form nerves.
Heredity is the passing of genes from parent to offspring
A purified protein has a molecular mass of 360 kDa when measured by size exclusion chromatography. When analyzed by gel electrophoresis in the presence of SDS, three bands are observed, with molecular masses of 160, 140, and 60 kDa. When gel electrophoresis is carried out in the presence of SDS and dithiothreitol, three bands are once again observed, with molecular masses of 140, 80, and 60 kDa. What is the subunit composition of the protein?
Answers
Answer:
A protein has four subunits whose molecular masses are 140, 80, and 60 kDa.
A disulfide bond links the two 80 kDa subunits (possibly identical).
Explanation:
Given that:
A protein has four subunits whose molecular masses are 140, 80, and 60 kDa.
A disulfide bond links the two 80 kDa subunits (possibly identical).
As a result of SDS and dithiothreitol analysis treatment, the molecular masses can not be 360 in total. They are 280, which implies that they are in short of 80 kDa. This means that there are possibilities that two groups with a molecular mass of 80 kDa which are joined by a disulfide bond.
The presence of SDS and dithiothreitol acts as a reducing agent, and they can break disulfide bonds whose pH is greater than 7, i.e. those in basic condition.

from the circular movement of hot and cold air
from solar radiation entering the atmosphere
from the conduction of heat from the ground to the air
Answers
Answer:
from solar radiation entering the atmosphere
Explanation:
The energy within the greenhouse effect is originated from solar radiation entering the atmosphere, hence option C is correct.
What is solar radiation?Solar radiation is a broad word for the electromagnetic radiation that the sun emits. It is also sometimes referred to as the solar resource or just sunshine.
A variety of devices can be used to collect solar radiation and transform it into useful forms of energy, such as heat and electricity.
Heat is reflected into the atmosphere from solar energy that has been absorbed in the earth's surface.
Greenhouse gases absorb a large portion of the heat as it travels through the atmosphere and is radiated back into space.
Therefore, the greenhouse effect is powered by solar radiation that reaches the atmosphere.

What mistake did Dominic make?
The title should read "Properties of Solutions" because some mixtures do not have all of the properties listed
O There is a definite recipe to make each mixture, so the composition of a mixture is set.
Although it is possible to have more than one state, it is also possible to have only one state.
O A single substance can be used to make a mixture if the substance is composed of more than one element

Answer:
Although it is possible to have more than one state, it is also possible to have only one state.
Explanation:
The mistake Dominic made was stating that "although it is possible to have more than one state, it is also possible to have only one state."
Mixtures are impure substances with the following properties:
They have an indefinite composition
Their constituents retains their identities.
Constituents react differently to changed conditions.
They can easily be separated into constituents by physical methods.
There are two types of mixtures based on the number of phases coexisting:
Homogeneous mixtures have their constituents existing in just one phase.
Heterogeneous mixtures exists in at least two different phases.

Oxygen ⇒ OSulfur ⇒ SSelenium ⇒ SeTellurium ⇒ TePolonium ⇒ Polivermorium ⇒ UuhValence electrons refer to the electrons an element has on its outermost shell. The number of these electrons determines the charge that an electron will carry as it seeks stability.
It also determines which group the element will be in in the Periodic table. Elements with 1 valence electron for instance will be in Group 1 and elements in Group 16 will have 6 valence electrons.
