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
Answers
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.

_________are organisms capable of transforming one
form of energy (light energy or chemical energy) into the food
they need to do work.
Answers
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.

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)
Answers
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
Why does DNA need to be extracted from a cell before it can be analyzed?
Answers
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.

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.
Answers
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).
