Answer:
B
Explanation:
Hydrogen and Oxygen are the most abundant gases, being the first, and third most abundant.
Hope this helps, googIe only wanted to give me explanations on why Hydrogen is the most common element in the universe :/
The form of hydrogen and oxygen that are most common on Earth's surface is known as Gas. Thus, the correct option for this question is B.
What is the difference between hydrogen and oxygen?The difference between hydrogen and oxygen is that oxygen significantly contains eight electrons and eight protons while hydrogen contains only one electron and one proton. Oxygen is present in 21% of the earth's atmosphere, while hydrogen is present in 0.03% which is negligible.
According to the context of this question, oxygen is the first and most abundant gas in the earth's atmosphere and hydrogen is the third most abundant gas.
They are also present in the liquid and solid states but are in negligible amounts when treated with abnormal conditions like lower temperature and freezing.
Therefore, gaseous forms of hydrogen and oxygen are most common on Earth's surface. Thus, the correct option for this question is B.

Answer:
a=to make additonal cells of the same type in response to a demand. b= synthesize enzyme to metabolize a particular nutrient
a=to make additonal cells of the same type in response to a demand. b= synthesize enzyme to metabolize a particular nutrient.
What is regulating gene?The mechanism by which genes are regulated affects when, where, and how much they are expressed.
Regulational proteins and chemical modifications to DNA are just two of the many mechanisms that can be used to carry out the process, which can be intricate. The ability of an organism to react to environmental changes depends on gene control.
One of the key functions that a cell does and one to which a significant portion of its energy is allocated is gene regulation. Gene regulation is one of the fundamental processes that a cell carries out in order to produce the transcripts that will result in the proteins.
Therefore, a=to make additonal cells of the same type in response to a demand. b= synthesize enzyme to metabolize a particular nutrient.

Which statement about the energy yields from cellular respiration is true? The heat produced during cellular respiration is only a tiny fraction of the chemical energy available in a glucose molecule. Cellular respiration is more efficient at harnessing energy from glucose than car engines are at harnessing energy from gasoline. Cellular respiration converts all of the energy in glucose into energy in ATP. Cellular respiration converts the kinetic energy of glucose into chemical energy.
Answer:
In a eukaryotic cell, the process of cellular respiration can metabolize one molecule of glucose into 30 to 32 ATP. The process of glycolysis only produces two ATP, while all the rest are produced during the electron transport chain.

Explanation:
Imagine if humans evolved in a low-gravity environment, where muscles didn’t need to work so hard against the gravity of our heavy bodies. How might human bodies look and function in such environments compared to how we look on Earth? What about in an especially high-gravity environment
We would be taller
We would be more fat
We would require more exercise
We would get unhealthy more quickly
We would be able to do many things that are not easy on Earth
We would not be able to do somethings that are easy on Earth
We would have more muscles, less bones
High-GravityWe would be Short
We will be thin
We will not require that much exercise
We will be usually healthy
Heavy people will suffer from disease more
A little weight increase can make lots of differences in the body.
Thanks!
Low-Gravity environments are particularly high-gravity. We'd be taller, fatter, need more exercise, and get sick faster; we'd be able to accomplish a lot of difficult tasks here on Earth; and we'd have more muscles and fewer bones, making it impossible for us to perform simple tasks here on Earth.
What distinguishes low from high gravity?A low gravity dam has a height that is less than Hmax. A high gravity dam is one whose height exceeds Hmax. A gravity dam is referred to as a low dam if the base width is designed with the resultant falling as close to the extremities of the middle third of the base as possible. Brewing a beer with a high original gravity (OG) typically, anything above 1.075 OG is considered high. Before fermentation, OG is a measure of the fermentable and unfermentable substances in the wort. Because volume is pressure dependent, the same mass will have a higher density if compressed to a smaller volume because it reduces the denominator of the density equation.To learn more about low from high gravity refer to:

Question: Is the pelvis a long or short bone?
Thank you!
Answer:
There are flat bones in the skull (occipital, parietal, frontal, nasal, lacrimal, and vomer), the thoracic cage (sternum and ribs), and the pelvis (ilium, ischium, and pubis). The function of flat bones is to protect internal organs such as the brain, heart, and pelvic organs.
Answer:
Long Bone!
Explanation:
Short bones include the carpal bones of the hands that allow movement of the wrist and the tarsal bones of the feet that allow movement of the ankle. Short bones are shaped roughly like a cube and contain mostly spongy bone. The outside surface is comprised of a thin layer of compact bone.
and
Long bones are hard, dense bones that provide strength, structure, and mobility. The thigh bone (femur) is a long bone. A long bone has a shaft and two ends. Some bones in the fingers are classified as long bones, even though they are short in length. This is due to the shape of the bones, not their size.

Why are hydrogen bonding and polarity so important for water molecules?
Answer: each water molecule attracts other water molecules because of the opposite charges between them, forming hydrogen bonds
Because of their significant influence on the characteristics of water, hydrogen bonding and polarity are essential to water molecules.
Hydrogen bonds can form between adjacent water molecules due to the polarity of water, with the oxygen atom being slightly negative and the hydrogen atom being slightly positive. Water's high surface tension, cohesive properties, and ability to dissolve various compounds are all affected by these hydrogen bonds.
Additionally, water has a large heat capacity due to hydrogen bonding, which allows it to slowly absorb and release heat, thereby regulating the temperature of both living things and their environment. Hydrogen bonding also contributes to the anomalous density of water, which reaches its greatest density at 4 °C.

On the EDL graph x-axis, click the time that represents where the twitch starts
Assuming that the twitch occurs when the muscle contracts, the time that represents where the twitch starts is approximately 400ms.
What is a twitch muscle contraction?
It refers to the muscle contraction by the nervous system due to an external stimulus.
Different techniques use twitches to study the contraction of the muscle fibers. For instance, Interpolated Twitch Technique measure the extent of voluntary muscle activation.
There are different phases through which the muscle goes since it gets the stimuli,
There is a lag phase between the activation of the motor cells and the fiber contraction. During this time, the action potential moves through the motor neuron.The contraction phase occurs when the muscle gets actually contracted, during which actin and myosin interact.
The relaxation phase is the last one to occur, in which troponin blocks the binding sites of myosin, so it can not interact with actin. The muscle relaxes.
Assuming that the twitch occurs when the muscle contracts, the time that represents where the twitch starts is approximately 400ms.
