Answer:
B Low Solar Activity
Explanation:
Fluctuations in the amount of insolation (incoming solar radiation) are the most likely cause of large-scale changes in Earth's climate during the quaternary.
Answer:
Decomposers recycle essential nutrients back into an ecosystem
Explanation:
An ecosystem works thanks to the constant transformation of energy. The role of the decomposers will be to transform energy into something useful in the ecosystem. For example, The bacteria which will rotten the apples that fall from a tree onto the ground are recycling or making available this energy for other organisms to use it. As part of this example, the essential nutrients of the apples will be available to be reabsorved by the roots of the apple tree thanks to the transformation of energy done by the bacteria in the apples.
Answer: 
1.922x10⁻²⁰ Joules
Explanation: <u>Electric</u> <u>Potential</u> <u>Energy</u> (U) is the energy a charged object has due to its location in an electric field and it will only exist with the object is charged.
<u>Voltage</u> or <u>Electric</u> <u>Potential</u> <u>Difference</u> (V) is external work done to move a charge from one point to another in a electric field.
These terms have a relationship, which is given by:
where
q is the charge
Proton is positive and has a charge of 1.6x10⁻¹⁹C.
Unit for potential energy is Joule (J). The relation between mV and J is
1mV = 10⁻³J
Then:
V = 120x10⁻³
V = 0.12
So, for a proton to move from the negative side of a membrane to the positive:
= 1.922 x 10⁻²⁰
Energy necessary to transport a proton from negative side of the membrane to the positive is 1.922 x 10⁻²⁰J.
Answer:
Phenotype
Genotype
Explanation:
Phenotype is the physical appearance because it's the outward expression of the person, which is determined by one's Genotype.
Answer:
Out of the Hab.
Explanation:
The atmospheric pressure on Mars is less than 1% of Earth's atmospheric pressure (0.088 psi) so if the airlock fails then the potato plants in the Hab will be pulled outside of the Hab because of the low pressure outside.
I hope this answer helps.
