Answer:
Dominant = Always / Recessive = Sometimes
Explanation:
I don't know how to explane this but my teacher thought me if it's Dominant it always Recessive in another way of sometimes.
The frequency of expression of dominant and recessive traits can be Dominant traits = always / Recessive = sometimes.
According to the question if there is self cross TT×tt then there is TT, Tt, Tt and tt, which means there is a 75% possibility of dominant trait and 25% recessive.
How Dominant and Recessive traits are different from each other?
Dominant traits are always described when the related allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive.
Thus, the option "C" Dominant traits = always / Recessive = sometimes.

What is the frequency of a photon with an energy of 3.38 x 10-19 J?
A. 6.71 x 1014 Hz
B. 5.10 1014 Hz
C. 1.96 1014 Hz
D. 4.47 1014 Hz
Answer:1.96*10^14 Hz
Explanation: energy = frequency*Planck constant
3.38*10^-19 J= frequency Hz*6.62607015*10^-34 Jsec
freq Hz = 3.38*10^-19/6.62607015*10^-34 = about 2*10^14

Are gender traits completely a result of societal expectations?
[tex]\huge\star{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}\star[/tex]
No. Gender traits in humans are largely determined by biophysical processes. There seems to be a vocal political faction that is trying to convince people in the name of liberty and equality that gender traits are completely learned, and therefore arbitrary.
But this claim disagrees with scientific evidence. In general, boys play more with cars and girls play more with dolls not because their parents are perpetuating outdated gender stereotypes, but because their brain is telling them to.
This fact does not mean that boys have to play with boy toys, or that boys who play with dolls aren't really boys. It is just a scientific observation about average behavior and its link to fetal development
According to the passage, what causes mutations during protein synthesis?

Natural selection causes what to occur?
1. evolution
2. survival of the fittest
The law of independent assortment
3. Mendel's law of segregation
4. genetic drift
Answer:
(1.) Natural selection causes evolution to occur.
Explanation:
Over time, the naturally occurring variation within a population that arise from mutations, alter in frequency. Some of these variants or traits, may confer advantages to certain organisms, allowing them to reproduce and pass on genes more successfully. These traits become fixed within the population, and eventually the individuals evolve to form a species.
Natural selection, acts on evolution, for or against traits. It ensures that individuals with traits well-suited to their environments and reproductive fitness survive.
Answer:
1. evolution
Explanation:
Natural selection causes populations to become adapted, or increasingly well-suited, to their environments over time. Natural selection depends on the environment and requires existing heritable variation in a group.

A change in the nucleotide sequence
produced during DNA replication
DNA is a dynamic and adaptable molecule. As such, the nucleotide sequences found within it are subject to change as the result of a phenomenon called mutation. Depending on how a particular mutation modifies an organism's genetic makeup, it can prove harmless, helpful, or even hurtful.
Coracias garrulus is a blue bird with an orange-brown back. The offspring of this bird have an effective defense mechanism. The young birds vomit and cover themselves in a foul-smelling orange liquid when they sense a threat by predators. Which two systems alert the young bird to the danger and help produce the vomit it uses as a defense
Answer:
The correct answer is - Nervous and digestive systems.
Explanation:
Coracias garrulus is a bluebird that has a unique defense mechanism in which it senses the danger or threat they vomit and cover themselves with their foul-smelling orange-yellow vomit.
The orange vomit or liquid store in the digestive system of the bird and when the bird's sense threatens it activates its nervous system which then intern sends a signal to the digestive system and the urge of vomit on its young ones and cover in that.
The nervous and digestive systems are the body systems that alert the young bird to danger and help produce the vomit it uses as a defense.
The nervous system is a body system by which animals coordinate actions and sensory information such as alert signals.The nervous system transmits signals to different parts of the body including the digestive system.The digestive system is the body system that acts to digest foods, having reflexes that allow to eliminate them by vomiting.In conclusion, the nervous and digestive systems are the body systems that alert the young bird to danger and help produce the vomit it uses as a defense.

Suggest two specific reasons why determining the cause of death can sometimes be difficult.
Answer:
1. The person has been dead for a while so the body is old.( Decomposed)
2. The manner or cause of death (injuries)
Explanation:
1.
Determining the cause of death could be difficult if the person has been dead for sometime. This is going to make the body to be more decomposed since the body has become old.
2.
Another reason is if the cause of death is from an accident and the dead person sustained great injuries. The condition of the body would be poor and this is going to make examination difficult.

A Photosynthesis releases energy when carbon dioxide and water combine to form glucose molecules.
B Photosynthesis releases energy when the reactants rearrange and form the bonds in the products,
Photosynthesis stores energy because energy is released when glucose is formed from carbon dioxide and water.
D Photosynthesis stores energy because more energy is stored in glucose than it is in carbon dioxide or water.
Answer:
Photosynthsis stores energy because more energy is stored in glucose than it is in carbon dioxide or water is the correct answer.

Explain what happens when a population experiences uncontrolled exponential growth.
Answer:
If the population ever exceeds its carrying capacity, then growth will be negative until the population shrinks back to carrying capacity or lower. Some disadvantages of having uncontrolled are the rapid urbanization associated with the population explosion and industrialization has created an imbalance in the ecology of the Southeast Region.
Explanation:
Answer:
When a population experiences uncontrolled exponential growth, the population will increase uncontrollably, leading to more resources being used and reaching the carrying capacity sooner.

Give an example of how using soil, trees, or air might result in a tradeoff
Answer:
As trees grow, they help stop climate change by removing carbon dioxide from the air, storing carbon in the trees and soil, and releasing oxygen into the atmosphere. Trees provide many benefits to us, every day.Explanation:
sorry if that doesnt help but hopefuly it does:)
By using soil, trees and air will result in a trade off due to increasing in one factor and decreasing in another factor.
Using soil, trees and air result in a tradeoff by using the carbondioxide gas in the atmosphere. The trees increase in high and vegetative growth by decreasing the carbondioxide gas in the atmosphere. In tradeoff, one thing increases, and the another must decrease.
So if the trees grow in size the concentration of carbondioxide gas decreases due to the process of photosynthesis by the tree so we can conclude that using soil, trees and air will result in a trade off due to increasing in one factor and decreasing in another factor.

a-t base pairs in a dna double helixare chemically distinct from G-C base pairs. form three hydrogen bonds with each other. are more heat stable than G-C base pairs. are not accessible to DNA binding proteins. are of a different length than G-C base pairs.
Answer:
A-T base pairs in a DNI double helix are chemically distinct from G-C base pairs.
Explanation:
Nitrogenated bases that form nucleic acids correspond to purines and pyrimidines. Adenine and guanine derive from purines, while Thymine and Citocine derive from Pyrimidines.
In the DNA molecule, Adenine (Purine) always form pairs with Timine (Pyrimidine), while Guanine (Purin) form pairs with Cytosine. Two hydrogen bonds unite the pair A-T, while three of them unite the pair G-C.
The structure of these bases is different hence, the chemical structure of the pairs is also different.
