The answer is option A : cell theory
Why do offsprings look different from there parents?
Living things produce offspring of the same species, but in many cases offspring are not identical with each other or with their parents. Plants and animals, including humans, resemble their parents in many features because information is passed from one generation to the next.
What happens when living things get in the dirt?
What types of stems are in plants?
O Aerial
O Subterranean
O Acaulescent
O All of the above
The copper wire is cut into three pieces of unequal lengths. All three pieces of copper would have (1 point)
A the same mass
B the seſme physical properties
C different crystal structures
D different arrangement of atoms
B.) The same physical properties.
Also the copper wire would also have the same Chemical Properties. They wouldn't have a different arrangements of atoms because that would mean they are a different substance. They wouldn't have the same mass whereas they are now in 2 pieces. Copper is not a crystal meaning it would not have any crystal structures. That leaves the only applicable answer to be B. Also in case you need to find whether or not two identical substances are the same would be by testing the melting point, hardness and solubility. I just finished working on this section in my own 8th grade Science class so I think this should either help you now or later on.
Hope this helps.

Explain the relationship between codon and gene.
Answer:
A codon is a trinucleotide sequence of DNA or RNA that corresponds to a specific amino acid. The genetic code describes the relationship between the sequence of DNA bases (A, C, G, and T) in a gene and the corresponding protein sequence that it encodes. The cell reads the sequence of the gene in groups of three bases.

Sickle-cell anemia is a recessive trait in humans. In order to express the disease, an affected individual must inherit two recessive alleles (ss).

Answer:
1/4 will have ss trait
Explanation:
other 2/4 will be carrier(Ss) and other 1/4 will have both dominant trait (SS)
Answer:
B. 1/2
Explanation:
The genotypes of the parents are Ss and Ss. We know this because Heterozygous basically means different alleles. The punnet square of this problem will show that the possible genes given to the offspring are SS (capital letters mean dominant. keep in mind that sickle-cell anemia is a recessive trait, meaning it is written in lowercase), Ss, Ss, or ss. So this means the offspring will have a 1/2 chance of becoming heterozygous (Ss).
Find out two types of water purification and name and describe them here.
Answer:
1. Reverse Osmosis
Reverse Osmosis works by forcing feedwater through a semi-permeable membrane.
A pump is used to apply pressure to reverse the normal osmotic flow across a membrane, meaning purified water molecules (permeate) are forced through the reverse osmosis membrane and recovered in preference to contaminants in the concentrated side which are left behind (reject concentrate).
2. Oxidisation
Oxidisation in the form of chlorination has been used as a means of water purification since the beginning of the last century. Hypochlorite is the key agent, achieving a disinfection of water by oxidising bacteria to eliminate waterborne diseases. Several different methods can be used to provide oxidation, including ozonation, chloramination, UV, bromination & chlorine dioxide. During the treatment, hydroxyl radicals are generated to destroy bacteria cells.

What is the best way to prevent contracting the influenza virus?
A.taking antibiotics B.getting a vaccination C.Drinking lots of water D.treating water supplies
Answer:
B. Getting a vaccination.
Explanation:
B. Getting A Vaccination
Influenza virus It is a respiratory virus because it infects the respiratory tract including the nose, mouth, bronchi and can even go further into the lungs to the alveoli and cause pneumonia. A person will spread the virus through coughing or sneazing that become airborne droplets. When a suceptible person comes in contact and breathes in these droplets, it causes an infection.

What is the energy source for producers, consumers, and decomposers?
Answer:
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.

HELLPPPPPPP THIS IS TIMEDDDDDD
Answer:
no
Explanation:
1) List 10 ways that energy is used in your home or outside of your home.
2) Now, imagine yourself having surgery in a hospital and the power goes out. What could be done that the surgery could continue?
Answer:
There are many ways to save energy at home some are as following:-
1)Use Led Bulbs rather than Tubelight
2)Using Heater or Air Conditioner uses a lot of energy so we should reduce there usage
3)If possible, install a programmable thermostat to automatically adjust your home's temperature settings when you're away or sleeping.
4)Use a bucket of water rather than taking a shower
5)During Winter season use suns heat to heat up your body rather than using heater at day time
6)Save water by scraping dishes instead of rinsing them before loading in the dishwasher
7)Close the tap when not in use
8)While brushing tour teeth, use utensils to clean your mouth rather than using a tap
9)The water you use to mop the floor can we used to water the plant or even clean your car
10)Dont use dryer to dry your cloth rather put it in under sun

What is an example of a codominate
phenotype?
Answer:
With a codominant trait, phenotypes like fur color are combined. For example, if a black-feathered chicken breeds with a white-feathered chicken, their offspring will be both black and white. They will not be gray; rather, there will be spots of both colors. Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB.

Can blood cells replicate themselves?
Answer:
Blood cells cannot replicate themselves.
Explanation:
They do not replicate like other bodily cells because they cannot independently process and create proteins. Blood cells are instead formed in the bone marrow of bones. Depending on whether it is RBC or WBC, there are different types of bone marrow for producing that type of blood cell.
Analyze the cell shown below. Which of the following accurately describes an
essential cell function being provided by the process shown?

how do cells use oxygen during cellular respiration
Answer:
In cellular respiration, cells use oxygen to break the sugar molecule. That releases the energy which is then transferred to an ATP (adenosine triphosphate) molecule. ATP is the fuel that cells need for energy. And where does cellular respiration happen?

The main difference between eukaryotic and prokaryotic cells is that eukaryotic cells have a nucleus.
The nucleus is where cells store their DNA, which is the genetic material.
The nucleus is surrounded by a membrane. ...
Explanation:
All prokaryotes are single-celled (unicellular) organisms.
