covered in ice?
The coal was transported by animals that ate the swamp plants.
The climate of Antarctica has become milder due to its closeness to the ocean.
The climate of Antarctica was probably much warmer in the past than it is today.
The coal was transported through large convection currents and uplift in the mantle.
Answer:
The climate of Antarctica was probably much warmer in the past than it is today.
Explanation:
There are little things living there now. Coal takes millions of years to form. There must have been much more living things there in the past (when it was warmer) to make coal.

Answer:
desert plants that need to conserve water like a cactus.
Explanation:
Thick fleshy stems with thick waxy covering would most likely be useful adaptations for desert plants to conserve water.
What are desert plants?Desert flora that require water conservation Prairie plants that must withstand flames desert flora that require water, conservation thick waxy covering would most likely be a useful adaptation.
The challenge for plants that thrive in highly dry environments is finding and retaining water.
Xerophytes are plants that can survive in extremely arid conditions. Their adaptations may aid them in consuming more water, reducing water waste, or storing water for later use.
Therefore, water is so scarce in deserts, plants there need to minimize water waste. They have thin foliage that enable them to retain more water during the summer.

Some benefits of dietary fiber are build muscle and flexibility.
True or False
Answer:
true
Explanation:
dietary fiber build muscle and flexibility
Dietary fiber is one of the components of a nutrient and balanced diet. Dietary fiber in the diet can build muscle and flexibility. Thus, the statement is true.
What is dietary fiber?Dietary fiber along with the functional fibers makes the total fiber that makes part of the diet and is considered to be nutritious. They are homopolysaccharides that are made of various similar monomers linked concurrently by the glycosidic linkage.
Dietary fiber is composed of various units of cellulose linked chemically by the beta (1 - 4) glycosidic linkage. They have been known as roughage which are plant parts that are undigestable. Though they cannot be absorbed, but they ensure a smooth digestive and excretory process.
The presence of dietary fiber in the diet increases flexibility and muscle mass by decreasing body fat and is found in beans, broccoli, avocados, berries, apples, etc. It eliminates fats and other wastes from the body by promoting regular bowel movements.
Therefore, the statement is true.

A Tomato Has A Proton Concentration Of 0.00006 M. How Would You Calculate The PH?
Answer:
Option b. is correct
Explanation:
If hydronium ion concentration [tex]H_3O^+[/tex] is given then pH is given by [tex]-log[H_3O^+][/tex]
The hydronium ion refers to the hydrogen ion in aqueous solution.
A Tomato has A Proton Concentration Of 0.00006 M
Here, 0.00006 is equal to 6 × [tex]10^{-5}[/tex]
So,
pH is given by - log [6 × [tex]10^{-5}[/tex]]
Option b. is correct
The pH of the tomato which has a proton concentration of 0.00006 M is given by –Log (6×10¯⁵)
The correct answer to the question is Option B. –Log (6×10¯⁵)

What’s the difference in concentration of hydronium Ions between pH1 and pH4?
a) x 2.6
b) x 1000
c) x 4
d) x 10
Answer:
The difference in concentration of hydronium Ions between pH1 and pH4 is 1000 times.
The difference in concentration of hydronium Ions between pH1 and pH4 is - Option b) x 1000.
pH scale is a scale or measure to find the strength of acidity or basic nature of a solution or substance. pH 1 is acidic and pH 14 is most basic on scale.
Acids combine with water molecules to form hydronium ion, H3O+. Therefore, pH formula in aqueous solution becomes-
pH = - log [H3O+].
taking antilog on both the sides, the concentration would be calculated as
[H3O+] = antilog (- pH)
In the first case, pH given is 1. So,
=> [H3O+] = antilog (- 1)
= 0.1
In the second case, pH given is 4. So,
=> [H3O+] = antilog (- 4)
= 0.0001
Thus, the concentration of hydronium ion at pH 1 is around 1000 times greater than that of concentration at pH 4.

Neurons, as with other excitable cells in the body, have two major physiological properties: ____________ and ____________. A neuron has a positive charge on the outer surface of the cell membrane due in part to the action of an active transport system called the ____________. This system moves ____________ out of the cell and ____________ into the cell. The inside of the cell membrane is negative, not only due to the active transport system but also because of ____________, which remain negative due to the intracellular pH and keep the inside of the cell membrane negative.
Answer:
Neurons, as with other excitable cells in the body, have two major physiological properties: irritability and conductivity. A neuron has a positive charge on the outer surface of the cell membrane due in part to the action of an active transport system called the sodium potassium pump. This system moves sodium (Na+) out of the cell and potassium (K+) into the cell. The inside of the cell membrane is negative, not only due to the active transport system but also because of intracellular proteins, which remain negative due to the intracellular pH and keep the inside of the cell membrane negative.
Explanation:
Neurons are cells with the capacity to transmit information between one another and also with other tissues in the body. This information is transmitted thanks to the release of substances called neurotransmitters, and this transmission is possible due to the electrical properties of the neurons.
For the neurons (and other excitable cells, such as cardiac muscle cells) to be capable of conducting the changes in their membranes' voltages, they need to have a resting membrane potential, which consists of a specific voltage that is given because of the electrical nature of both the inside and the outside of the cell. The inside of the cell is negatively charged, while the outside is positively charged - this is what generates the resting membrane potential. When the membrane voltage changes because the inside of the cell is becoming less negative, the neuron is being excited and - if this excitation reaches a threshold - an action potential will be fired. But how does the voltage changes? This happens because the distribution of ions in the intracellular and extracellular fluids is very dissimilar and when the sodium channels in the cell membrane are opened (because of an external stimulus), sodium enters the cell rapidly to balance out the difference in this ion concentration. The sudden influx of this positively-charged ion is what makes the inside of the neuron become less negative. This event is called depolarization of the membrane.
Please help!!! how can a sedimentary rock become a sedimentary rock???
Answer:
Sedimentary rocks are made of sand, gravel, mud and other materials. They go through a 5 step process to be made.
Explanation:
1) first weathering breaks down material that will be used to form the rock.
2) next erosion picks up the sediment via wind, water, or glacier
3) the sediment is then transported via wind, water, or glacier
4) Then deposition occurs. (depositing the sediment)
5) Lithification (turning the sediment to rock)
