Answer:
True
Explanation:
In the levels that make up the organization of life, CELLS are the smallest and simplest components of life. According to the hierarchy, cells make tissues, tissues make organs, organs make organ systems, organ systems make organisms. Based on this question, the DIGESTIVE SYSTEM falls under the SYSTEM category of the hierarchy meaning that it comprises of organs performing similar functions that makes it up.
However, these organs as well contain tissues and subsequently cells which makes up the digestive system. Since the cells, tissues, and organs all work together for the process of digestion, it means that the cells found in the digestive system are SIMILAR to one another in appearance.
Rhonda Runsalot is a 20 year old woman. She is running at VO2max. Her heart rate is 200 b/min. Her stroke volume is 100 ml blood/b. Her arterial oxygen content is 20 ml O2/100 ml blood. Her venous oxygen content is 6 ml O2/100 ml blood. What is her cardiac output?
Answer:
Cardiac output = 20 L/min
Explanation:
The cardiac output of a person refers to the volume of blood the heart pumps in a minute. The normal range for cardiac output is about 4 to 8 L/min. However, this can vary depending on the metabolic needs of the individual at any instant of time, for example, it is higher when exercising than when resting.
Cardiac output is calculated from the product of the stroke volume in liters/min and the heart rate in beats/min
Cardiac output = stroke volume * heart rate
For the individual who is running; stroke volume = 100 mL/beat or 0.1 L/beat
heart rate = 200 beats/min
Cardiac output =0.1 L/beat * 200 beats/min
Cardiac output = 20 L/min

Describe any three factors that could have an impact on the rate of photosynthesis. In other words, what types of conditions placed on a plant would speed up or slow down photosynthesis?
Answer:
Sunlight, temperature and geography.
Explanation:
1. The plant requires a certain amount of sunlight to create ATP (Energy)\
2. If the weather is too hot or too cold the plant will not be able to maintain a stable life and slowly wither.
3. Plants need a certain environment to maintain life. such as soil and H2O.
A codon can be found on which?
mRNA
ORNA
ORNA
Answer:
a codon can be found on mRNA
Explanation: codons are created when groups of nucleotides are conected to form a animo acid. the formation is all in the mRNA then the animo acids combine to form proteins. proteins are formed when animo acids are "dehydrated" and form a water molecule then the rest combine into a protein and that protein can be in any form for various tasks.

Large molecules have very specific functions, specifically in the body. This particular molecule
helps to maintain glucose levels in the blood and is released from the pancreas. What is this
organic molecule?
A)
starch
B)
hemoglobin
C)
steroids
D)
insulin
Answer:
D) Insulin
Explanation:
Insulin is an organic molecule, specifically a protein molecule, which is produced by the pancreas. It is an enzyme that regulates the level of glucose in the blood. Insulin carries out this function by converting excess glucose in the blood into a stored form called GLYCOGEN.
The glycogen, which is stored in the liver, is converted back to glucose when the need arises for glucose in the blood. Hence, INSULIN is that large organic molecule (protein) that helps to maintain glucose levels in the blood and is released from the pancreas.

The process of antibody-dependent cellular cytotoxicity (ADCC) allows ______ cells to bind to antibody-coated host cells that may have viral proteins in their plasma membrane in order to kill them, inducing apoptosis and limiting viral spread.
Answer:
The right response is "Natural killer".
Explanation:
Natural killer cells constitute immune cells which could also identify and ultimately destroy distressed or damaged cells. This might also target cancerous as well as tumors. That alone reduces inflammation that lyses this same cell cycle rather than being amongst the very first cells towards prepare an inflammatory system, and even more so towards virus cells, participating including its destruction.What is formed when two substances are in the same container, but no

Answer:
Estimate
Explanation:
An estimate is defined as a reasonable assumption.
An approximation of a number, based on reasonable assumptions, is called estimation.
What is an Assumption?An assumption may be defined as an incident of accepting something true without any valid question or accurate proof. The assumptions may be falsified at any time. This is because it never contains some solid evidence.
Estimation is something that is predicted without any actual consent. It is just an approximation of numbers, objects, data, or any other thing that is only based on reasonable assumptions. The same concept is held by estimation as well.
Assumptions and estimations both have identical meanings to one another. This is because the principles or measurement of both depends on only approximation. They never represents the things based on accuracy and validity.
Therefore, an approximation of a number, based on reasonable assumptions, is called estimation.

By the time a cell has reached metaphase, all the following have occurred except...
Answer:
C. Sister chromatids separate
Explanation:
During interphase, which is composed of the G1 phase, S phase and G2 phase, the cell grows and replicates its DNA and some of its organelles. During the S phase, the genetic material is duplicated into two sister chromatids, and centrosomes, which are nucleated microtubules that interact with the chromosomes to form the mitotic spindle, are also replicated. Metaphase is the third phase of mitosis, where sister chromatids align in the middle of the cell before their separation into two daughter cells.
