Answer:
Adrenaline
Explanation:
The adrenaline glands, located on top of both kidneys, are glands that produce hormones to regulate blood pressure, bodily functions, metabolisms, etc. Adrenaline is released whenever the blood is redirected towards the muscles, causing surges of energy. In general, adrenaline increases blood flow in your body, which causes the heartbeat to increase, or give the feeling of a racing heart. Between the football players and the heartbeat rate, they are getting rushes of adrenaline from either participating in the game or cheering on their team from the sidelines. Hope that made sense.

5. The ribosome releases both the mRNA molecule and the polypeptide (protein)
During protein synthesis, all the machinery for synthesis occurs in a sequential manner and the first need is a DNA template, so the correct option is a.
What events occur during protein synthesis?Protein synthesis occurs in the ribosomal machinery and the process is called translation and starts after transcription.
DNA acts as a template for transcription and makes mRNA which translates into protein. mRNA act as a messenger for protein synthesis, this mRNA converts into protein with the help of ribosomal machinery.
In the process tRNA act as an adapter molecule adding an amino acid to the protein chain according to the codon on mRNA. In the last step protein and mRNA are released by the ribosome.
Therefore protein synthesis starts with DNA, hence option a is correct.

In chloroplasts, when the two photosystems work in series, electrons ejected from the photosystems do not return to them, which is known as ______. Multiple choice question. oxygenic photophosphorylation cyclic photophosphorylation noncyclic photophosphorylation NADPH based photophosphorylation
When electrons do not return to the photosystems, it is because of a process known as oxygenic photophosphorylation, a process that is key to photosynthesis.
Photosynthesis is the process by which plants get their energy. This process involves many steps taken in order to turn energy from light, into sugar and molecular energy known as ATP, needed for plants to survive. This process uses a variety of important and complex steps, among which is included oxygenic photophosphorylation.
Oxygenic photophosphorylation is one of the key processes to photosynthesis. It involves the use of photosystems one and three, located in the thylakoid membrane of plant cells, in order to produce NADPH and ATP. These systems enter a state of photoactivation, releasing an electron to be carried by the NADPH molecule towards the Calvin cycle where the electron can be placed onto a carbon atom, for long-term storage, often as a carbohydrate.

If 2x 2 + 13x – 7 = 0, then x could equal to which of the following?
Answer:3/13
Explanation:
Answer:
x = 1/2 and x = -7
Explanation:
you need to factor
multiply 2 x -7 to get -14
then find factors of -14 that add to give you 13
14 and -1 work
now rewrite the original equation but replace 13x with 14x - 1x
so 2x^2 + 14x - 1x -7 = 0
now factor by grouping
(2x^2 + 14x) (-1x - 7) = 0
factor the greatest common factor out of each group
2x(x + 7) -1(x + 7) = 0
the factors are (2x - 1) (x + 7) = 0
set each factor equal to zero and solve both for x
2x - 1 = 0 x + 7 = 0
+1 +1 - 7 - 7
2x = 1 x = -7
÷2 ÷2
x = 1/2

When referring to cell division, oncogenes are most like ________ while tumor suppressor genes are most like ________. the brakes on a car; the gas pedal on a car the steering wheel on a car; the gas pedal on a car the gas pedal on a car; the brakes on a car the brakes on a car; the steering wheel on a car
Oncogenes are most like the gas pedal on a car, while tumor suppressor genes are most like the brakes on a car. Oncogenes and tumor suppressor genes are mutated in cancer cells.
Oncogenes are genes overexpressed in cells in which they should not be expressed, thereby leading to cancer.
Some examples of oncogenes are growth factors such as, for example, the Platelet-derived growth factor (PDGF) or Epidermal growth factor (EGF).
Conversely, tumor suppressor genes are genes that act to regulate cell division and replication, thereby their inactivation also leads to cancer.
A well-known example of a tumor suppressor gene is the p53 gene that acts to control cell division and apoptosis (programmed cell death).

2. The amount of carbon-dioxide atoms released by respiration are exactly equal to the atoms of these materials contained in the oxygen and carbon converted. In this way respiration has conserved the mass or material and in this way followed the law of conservation of mass.
Explanation:
What is Cellular Respiration?
Cellular Respiration is the process in which the cells of living things break down the organic compound glucose with oxygen to produce carbon dioxide and water. The overall chemical equation for cellular respiration is:
C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (stored in ATP)
Cellular respiration takes place in the cells of all organisms. It occurs in autotrophs such as plants as well as heterotrophs such as animals.
Q: How is cellular respiration related to breathing?
A: Breathing consists of inhaling and exhaling, and its purpose is to move gases into and out of the body. Oxygen needed for cellular respiration is brought into the body with each inhalation. Carbon dioxide and water vapor produced by cellular respiration are released from the body with each exhalation.
Energy Changes in Cellular Respiration
The reactions of cellular respiration are catabolic reactions. In catabolic reactions, bonds are broken in larger molecules and energy is released. In cellular respiration, bonds are broken in glucose, and this releases the chemical energy that was stored in the glucose bonds. Some of this energy is converted to heat. The rest of the energy is used to form many small molecules of a compound called adenosine triphosphate, or ATP. ATP molecules contain just the right amount of stored chemical energy to power biochemical reactions inside cells.

Explain why a plant with a mitochondrial issue likely will not survive.
Mitochondria are cellular organelles that are in charge of oxidative phosphorylation, which is the critical process of turning nutrients into adenosine triphosphate (ATP) molecules that power normal cell operations. At least hundreds of mitochondria are found in each neuron. Because nerve cells are postmitotic, any mitochondrial damage received will accumulate over time and produce malfunction. Cells die as a result of widespread mitochondrial damage because they can no longer create adequate energy.
