What are viruses? How do you bacteria and viruses help human health?
Answer: I don’t believe viruses help health because they kill host cells and damage the host organism. However, after you survive a virus your body builds up a defense and it is highly unlikely you will catch the same virus.

_________are organisms capable of transforming one
form of energy (light energy or chemical energy) into the food
they need to do work.
Answer:
Producers/Autotrophs
Explanation:
Using carbon dioxide and water, plants convert carbon dioxide into glucose, and water into oxygen with the help of light energy to provide food for themselves. In a process called photosynthesis.
The organism that is capable of transferring one form of energy, which is light energy, to chemical energy, which is food, is the photoautotroph. These are the producers in the ecosystem, such as the plants.
What is the role of the photoautotroph?Every ecosystem contains some form of photoautotroph, such as land plants present in the terrestrial ecosystem, phytoplankton present in the aquatic ecosystem, etc. The photoautotrophs have special cell organelles, such as the chloroplasts, that carry out the conversion process of the light energy into chemical energy by the different complexes present in the thylakoid. ATP is formed during the photosynthesis process, and the carbon level in the atmosphere decreases as the plant uses it for this process.
Hence, the organism that is capable of transferring one form of energy, which is light energy, to chemical energy, which is food, is the photoautotroph. These are the producers in the ecosystem.

A. Scientists use a single system to prevent miscommunication.
B. Scientists have their favorite forms of units.
C. One scientists might have a better measurement than the other.
D. Scientists don't make enough measurements to need more then one system.
Answer:
The answer is A
Explanation: When it comes to using different types of units rather it is SI or NM they want to make sure they got the measurements right they don't want any mistakes when it comes to creating an experiment, data and report that can lead to a lot of miscommunication with other professional scientists. The other answers provided on here didn't really make sense so I believe the answer to this is A

Why does DNA need to be extracted from a cell before it can be analyzed?
Answer:
to study the genetic causes of disease and for the development of diagnostics and drugs.
Explanation:
It is important to extract DNA from a cell in order to study the genetic causes of disease and for the development of diagnostic and drugs. Scientists will use a cell culture system, which is cells from an organism that have either been made to continuously proliferate (grow) or are cancerous in nature (from cancer).
These cells allow us to continue working on experiments where we can change the conditions to determine various cell functions.

4. A scientist is observing living Cells in a Petri Dish under a Compound Light Microscope and recorded their
observations. Which of these observations provides evidence to support one of three components of "The Cell
Theory?" (SC.6.L.14.2)
a. Each Cell is spherical in shape.
b. Cells appear pink in color under the Microscope.
c. The sample of Cells require a nutrient broth as a food source.
d. Several Cells are in the process of dividing into two new Cells.
Answer:
D. Several cells are in the process of dividing into two new cells
Explanation:
The universal cell theory which was proposed in 1838 and contributed by three scientists namely: Theodor Schwann, Rudolf Virchow, and Mathias Schleiden, consists of three components namely:
1) Cell is the basic and functional unit of life
2) All living organisms are made up of one or more cells.
3) All existing cells arise from pre-existing cells.
Hence, in this question involving a scientist who is observing living Cells in a Petri Dish under a Compound Light Microscope, the observation that "Several cells are in the process of dividing into two new cells" provides evidence to support one of the three components of the cell theory ( all living cells arise from preexisting cells).

Brown eye color is a dominant trait and blue eye color is a recessive trait
What typically happens when someone inherits one allele for brown eyes and one for blue eyes?
O The person has brown eyes, and brown eye color remains a dominant trait
O The person has blue eyes, but brown eye color remains a dominant tralt
O The person has brown eyes, but blue eye color becomes a dominant trait
O The person has blue eyes, and blue eye color becomes a dominant trait
Answer:
The answer is the first choice, the person has brown eyes , and the color remains the dominant trait.
Explanation:
When a person inherits a recessive trait and a dominant trait, their (in this case) eye color will always be brown. The only time a recessive trait will be inherited (having blue eyes) occurs when the offspring inherits two recessive traits.
A. The person has brown eyes, and brown eye color remains a dominant trait this typically happens when someone inherits one allele for brown eyes and one for blue eyes.
What's an allele simple definition?An allele is one of two or more variations of DNA collection (an unmarried base or a phase of bases) at a given genomic area. A person inherits two alleles, one from every parent, for any given genomic vicinity where such a version exists.
What are alleles and examples?A dominant allele will override the tendencies of a recessive allele in a heterozygous pairing. In a few trends, however, alleles can be codominant—i.e., neither acts as dominant or recessive. An instance is the human ABO blood group machine; humans with type AB blood have one allele for A and one for B.

100 g of a mystery metal at 250 C is added to 400 mL of water at 15 C. The final temperature of the system is 15.9 C. What is the heat capacity
of the mystery metal?
(PLEASE HELP need the answer by 10/21/20
11:00pm)
Answer:
c = 0.064 j/g.°C
Explanation:
Given data:
Mass of metal = 100 g
Initial temperature of metal = 250°C
Volume of water = 400 mL
Initial temperature of water = 15°C
Final temperature = 15.9°C
Heat capacity of metal = ?
Solution:
First of all we will calculate the heat lost by metal into water.
ΔT= 15.9°C - 15°C
ΔT= 0.9 °C
q = mcΔT
q = 400 g× 4.184 j/g.°C × 0.9 °C
q = 1506.24 j
Specific heat capacity of meta;
ΔT = 15.9°C - 250°C
ΔT = -234.1 °C
q = mcΔT
-1506.24 j = 100 g× c × -234.1 °C
(negative sign with q value indicate heat is lost by metal)
-1506.24 j = -23410 g.°C × c
c = -1506.24 j /-23410 g.°C
c = 0.064 j/g.°C
