When a trait is always expressed, it is considered to be a
trait.
O Recessive
O Codominant
O Dominant
O Incomplete
Answer:
O Dominant
Explanation:
An allele that is always expressed whenever it is present is called dominant. Mendel's law of segregation states that the two alleles for a trait segregate independently when gametes are formed.
Hope this helped!!!!!
A dominant trait is a form of trait which is ALWAYS expressed.
A strand of mRNA that is 450 nitrogenous bases long will produce a protein containing approximately
Answer:
approximately 150 amino acids
Explanation:
Proteins are produced from genes via a process called gene expression. In this process, the gene-containing DNA is first transcribed into mRNA molecule, which is subsequently translated into an amino acid sequence that makes up the protein molecule.
However, during the translation process, the mRNA molecule is read in a group of three nucleotides called CODON i.e. a codon is made up of three nucleotide/nitrogenous bases. Each codon codes for a particular amino acid.
Since one codon of a mRNA that is three (3) nucleotides long codes for one amino acid, hence, strand of mRNA that is 450 nitrogenous bases long will produce a protein containing approximately (450/3) = 150 amino acids.
Use the model of meiosis that you made earlier in the lesson to explain how crossing over contributes to genetic diversity. How did you modify your model? How do you think crossing over affects the expression of certain traits compared to the cells where crossing over didn’t occur?
Answer:
Due to exchange of parts of chromosome.
Explanation:
Crossing over is the exchange of segments or parts of chromosome between non-sister chromatids in the meiosis cell division. Due to crossing over, new combinations of genes in the gametes are formed that are not found in both parent which leads to genetic diversity. Crossing over affects the expression of certain traits in the organism because the organism that crossing over have different features as compared to their parents so there is a big difference between organism have crossing over and no crossing over.

B. The inner planets are closer to the sun
Explanation:
The inner planets are actually smaller than the outer planets, all of the planets have moons, otherwise they're not considered a planet, and the outer planets, since they are FARTHER away from the sun have increasingly larger orbits.

mRNA vaccines are DIFFERENT from other vaccines in they: (Choose all that are different from other vaccines only)
Group of answer choices
-They do not use live viruses
-The vaccine with mRNA never enter the nucleus
-The vaccine uses inactive viruses
-The vaccine ilicits an immune response
-The cell breaks down the mRNA after it delivers its instructions.after
Answer:
-They do not use live viruses
-The vaccine with mRNA never enter the nucleus
-The vaccine ilicits an immune response
-The cell breaks down the mRNA after it delivers its instructions.
Explanation:
mRNA vaccines are a new class of vaccine which can be used to fight against infectious pathogens such as, for example, viruses. These vaccines are based on the design of a messenger RNA (mRNA) sequence that is introduced into de body to encode a protein of the pathogen (or even just a fragment of a protein) and consequently elicits an immune response after infection. Since pathogens need to produce many different proteins to be harmful to the host organism, a single mRNA molecule of the pathogen can trigger an immune response but does not cause the disease. mRNA vaccines don't enter into the nucleus of the cells and therefore they never interact with DNA. mRNA vaccines don't need viral vectors (e.g., adenoviruses) to be introduced inside the body. Moreover, traditional vaccines are those that use inactivated versions of the pathogen in order to trigger immune responses.

A park guide tells her that hoodoos like this one have been forming on Earth throughout history. Which principle explains the process that forms these rocks? A. erosion B. deposition C. weathering D. uniformitarianism
The principle that explains the process of forming hoodoos like this one is erosion. Therefore, option (A) is correct.
A hoodoo is a tall and thin rock formation characterized by a column of sedimentary rock that has been eroded over time, leaving a pinnacle or spire-like structure. Hoodoos are typically found in arid or semiarid areas with a high concentration of soft rock such as sandstone, limestone, or volcanic tuff. These formations are often created by a combination of factors such as water erosion, wind erosion, and frost weathering.
Hoodoos can take on various shapes and sizes and may be found singly or in groups, forming intricate and awe-inspiring landscapes. They are commonly found in national parks and other natural areas around the world, including the United States, Canada, China, and Australia, where they attract tourists and geology enthusiasts alike.

Sudhi is studying the motion of a toy car. She places the car in the middle of a ramp and releases it.
Hello. Your question is incomplete. However, when researching, I managed to find a question like yours and found that you forgot to mention that the question wants you to determine which is the best reference point in this scenario.
Answer:
The best point of reference is the starting position of the toy car.
Explanation:
To study the movement of the car it is necessary for Sudhi to establish a reference point, so that she can calculate all the variables associated with this movement. The best variable in this scenario is the starting position of the car, when it is still on the ramp. Thus, Sudhi needs to determine the distance between the car and the ground, that is, what the car's starting position is. She will be able to discover this when determining the height of the ramp.
what is the function the guard cell?
Answer:
Explanation:
Guard cells are located in the leaf epidermis and pairs of guard cells surround and form stomatal pores, which regulate CO2 influx from the atmosphere into the leaves for photosynthetic carbon fixation. Stomatal guard cells also regulate water loss of plants via transpiration to the atmosphere.
Answer:
regulate carbon dioxide and water input of a plant so the pant don't take in too much water or air

In a lake with three trophic levels (non-native fish, zooplankton, algae), an algal bloom occurs when the small population of zooplankton declines due to the predation of the invasive fish. Which of the following describes why zooplankton are the keystone species in this scenario?
Zooplankton are the smallest of all the herbivorous marine mammals in their communities.
The small population of zooplankton have an unequal effect on the marine community.
Marine mammals depend upon the work of zooplankton to convert sunlight into food.
Zooplankton help other populations survive by keeping out other herbivores.
Answers:
Zooplankton help other populations survive by keeping out other herbivores
Explanation:
This is because a keystone species are species that have large effect on the the habitat and through its effect they help to keep the ecosystem in existence. They make sure that the ecosystem exist. They help populations survive by keeping out herbivores and feeding on the algae. They help drive nutrients cycle and transfer energy from algae to invasive fish.
