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.

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.

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

What can cause genetic variation in a population?
Answer: by mutations when there is random fertilization and mating and when homogenous genes get together (especially if it is recessive) then a mutation can occur

Sickle-cell anemia is a recessive trait in humans. In order to express the disease, an affected individual must inherit two recessive alleles (ss).
What is the probability that the offspring of two heterozygous parents will also be heterozygous?
Choose 1 answer:
(choice A)
A
(choice B)
B
[tex]\frac{1}{4}[/tex]
(choice C)
C
[tex]\frac{1}{2}[/tex]
(choice D)
D
[tex]\frac{3}{4}[/tex]
(choice E)
E
[tex]\frac{4}{4}[/tex]
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).
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.

How is salinity affected?
(a) evaporation increases
(b) freezing increases
(c) melting increases
(d) precipitation increases
Answer:
Salinity of seawater is affected by evaporation, precipitation, ice formation, and ice melting. Evaporation increases the salinity of seawater because when seawater evaporates, the salts are left behind, thus increasing their concentration. ... Ice formation and melting behaves in a similar way.
Answer: evaporation increases
Explanation:
the first person meant evaporation increases
a sailboat moves faster as the wind blows on its sail. this is an example of acceleration, force, speed, velocity
Answer:
force
Explanation:
Gravity and buoyancy are the two key forces that operate on a stationary sailboat. The power of the wind pulls on the sail in order for the boat to move which allows the boat to move. The powers are now unbalanced, which is apparent from the acceleration of the ships.
The boat accelerates until the forward portion of the force from the sails is matched by the drag from the water.

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.

Explanation:
A dichotomous key is an identification technique that repeatedly divides groups of organisms into two categories.
What is Dichotomous key?More details regarding the unique characteristics of a given organism are disclosed with each successive division. Once the organism no longer exhibits all of the chosen traits in concert with any other organism, it has been recognized.
In order to identify specimens with a dichotomous key, it is recommended to employ immutable traits (i.e. features that do not change). Size, coloration, and behavioral habits can all change across people and over the course of a lifetime.
Better traits are produced by physical features (like the number of limbs) and biological processes (like the mode of reproduction). Typically, dichotomous keys are displayed in one of two ways.
Therefore, A dichotomous key is an identification technique that repeatedly divides groups of organisms into two categories.

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.
