Given that almost all organisms obtain energy from food by the process of cellular respiration, which is the most likely explanation for what prevents Earth from running out of oxygen? A. The net effects of the reactions of photosynthesis and cellular respiration are the opposite of one another, therefore the products of one are the reactants of the other, creating a cycle. B. The energy flow—and thus oxygen flow—for cellular respiration and photosynthesis take place in the same direction, and therefore build upon one another. C. Cellular respiration is a process that releases energy and oxygen, while photosynthesis withdraws energy and uses oxygen, therefore keeping each process in balance. D. Oxygen readily accepts electrons, so cellular respiration uses a negligible amount of oxygen.

Answer:
According to the image, the approximate QT interval is 0.4 seconds.
Explanation:
The QT interval is the space between the beginning of the QRS complex and the end of the T wave, which represents from the beginning of depolarization to ventricular repolarization.
Considering that the extandardized measurements of an EKG, where the paper circulates at a speed of 25 mm/s, 1 mm horizontal —measuring time— has an equivalence of 0.04 s.
In the image, there is 10 mm between the beginning of the QRS and the end of the T wave, so:
0.04 seconds X 10 mm = 0.4 seconds.
Then, the estimated QT interval is 0.4 seconds.

A new microorganism is isolated from a lake and is placed into a solution of KCl. The voltage difference across its membrane is measured at 120 mV. How much energy is required to move a proton from the negative side of the membrane to the positive side?
Answer: [tex]\Delta U=[/tex] 1.922x10⁻²⁰ Joules
Explanation: Electric Potential Energy (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.
Voltage or Electric Potential Difference (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:
[tex]\Delta U=q\Delta V[/tex]
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:
[tex]\Delta U=q\Delta V[/tex]
[tex]\Delta U=1.6.10^{-19}.0.12[/tex]
[tex]\Delta U[/tex] = 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.

Which statement describes competition in an environment? Organisms share a place to sleep. A living thing consumes berries on a tree. Sunlight shines only three months out of the year. A stream supplies an abundance of water in a forest.
Answer:
Sunlight shines only three months out of the year.
Explanation:
I think this is right
Because abundance means a large amount so there would be no competition there.
If organisms share a place to sleep then that means no competition
If a living thing is consuming berries on a tree then the living thing is just eating
But if the sunlight only shines three months out of the year then that can cause a shortage of food in the environment causing for the living creatures in the environment to compete for the food that is left since there won't be enough to supply for and abundance of living things.
The statement that describes competition in an environment is option B a living thing consumes berries on a tree. Thus, consuming berries on a tree is reducing the availability of the food for other livings depends on the berries.
What is survival of living things?In the nature, the concept that survival of the fittest domintates. The organisms which are fit physically and are smart to gather food will survive in the nature otherwise they will extincts.
An ecological community is a collection of populations of at least two distinct species that interact both directly and indirectly in a specific geographic area. Within this community, diffrent organisms can be found .
Numerous ecological characteristics and functions, including nutrient cycling and food webs, are based on interactions between species. Depending on the evolutionary context and environmental factors that they take place in, these interactions can have a variety of different natures.
Because of this, ecological interactions between particular individuals and entire species are frequently difficult to identify and quantify and depend on their scale and context they face extinction. Hence, option B is correct.

State the term used to describe an enzyme that functions within a cell.
Answer:
Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism
Explanation:
An intracellular enzymes can be referred to as endocyto enzymes. These are intracellular proteins that accomplish their function within the same cell that synthesized them. They can be either free in the cytosol or associated with an organelle -inside the organelle or fixated to it-.
--------------------------------------------
Enzymes are catalytic intracellular molecules or polypeptides that accelerate different natural chemical reactions. They have specific binding sites to substrate molecules and turn them into product molecules.
Enzymes are in charge of catalyzing cell metabolism. Since they are proteins, they share many properties with all polypeptides. One of these is that they have a limited temperature level at which they denaturalize.
According to the place where they accomplish their function, enzymes can be called
Plasm-specific enzymes ⇒ Their action field is the plasma ⇒ These are exportation proteins.Secreted or Exocyto enzymes ⇒ Their action field are tissues placed far away from where they were produced and released (for instance, the pancreas secretes and releases enzymes that accomplish their function in the duodene) ⇒ These are exportation proteins.Intracellular or Endocyto enzymes ⇒ All enzymes that accomplish their function within the same cell that synthesizes them ⇒ These are intracellular proteins.Within the cell, enzymes can be free in the cytosol, or fixated to an organelle.
Uniloculated enzymes ⇒ 100% cytosolic enzymes.Biloculated enzymes ⇒ They spend part of the time in the cytosol and part in organelles.--------------------------------------------------------

What is a major difference between DNA replication and DNA transcription?
Answer:
RNA molecules produced by transcription are much shorter in length than DNA molecules produced by replication.
Explanation:
In DNA transcription, only a segment of DNA is copied, or "transcribed," to a complementary strand of messenger RNA.
In DNA replication, the entire length of the DNA molecule is copied so that it can be passed to a new cell.

a.fission
b.budding
c.fragmentation
d.sporulatioin
Answer:
Budding
Explanation:
It is asexual reproduction in which offspring grows out of the parents organisms.
In the process of budding, an offspring grows off from the body of a parent organism and buds off when fully matured. Thus, the correct option is B.
What is Asexual Reproduction?
Asexual reproduction is the type of reproduction only a single parent is involved. In this process, offspring are developed from a single parent called mother cell and these offspring are genetically identical to the parent hence are also called as clones.
During the process of budding which is a types of asexual reproduction, a new organism develops from an outgrowth or bud which is formed on the parent plant due to the cell division at a particular site on the parent plant. For example, the small bulb-like projections coming out from the yeast cell are the buds which give rise to new yeast organism.
Therefore, the correct option is B.

One difference between weather and climate is that _____. climate is localized, and weather occurs over large areas. weather is localized, and climate occurs over large areas. weather is the day-to-day conditions, and climate is the conditions expected over relatively long periods of time. climate is the day-to-day conditions, and weather is the conditions expected over relatively long periods of time.
Answer:
Weather is the day-to-day conditions, and climate is the conditions expected over relatively long periods of time.
Explanation:
The difference between weather and climate is how long the period of time they refer to is.
Weather is what conditions of the atmosphere are over a short period of time, or day-to-day conditions. It's what we see on the weather forecast every day - whether it's going to be sunny or rainy today and tomorrow and similar.
Climate is what conditions of the atmosphere are over longer periods of time, usually 30 years. In fact, it's an average pattern of weather for a particular region. A description of a region's climate will include the precipitation, temperature, humidity, sunshine, wind velocity, phenomena such as fog, frost, and hail storms, and similar conditions.
