Answer:

An electron in an excited energy level of an atom will always drop to lower energy levels, emitting very specific wavelengths of light in the process.

Answer:

Explanation:

1. The genotype is Ff for  both

2 The phenotype is having freckles

3. FF, Ff, Ff, ff

4. 75% freckles 25% no freckles

Answer:

1.) Genotype = Ff

2.) Phenotype = having freckles

3.) Possible Genotypes = FF, Ff, ff

    Probability of each Genotype = 25% FF,  50% Ff, and 25% ff

4.) Possible Phenotypes = Freckles and no freckles

    Probability of each Phenotype = 75% freckles and 25% no freckles

Explanation:

1.) A genotype is the specific combination of alleles which give rise to a trait. Alleles are represented by the letters (F and f).

Heterozygous individuals have one of each type of allele. Therefore, the genotype of the couple is Ff.

2.) Phenotypes are the trait which the genotypes are expressing. When an allele is said to be dominant (like the F allele), it means that individuals with at least one of these alleles will express the associated trait. Remember, heterozygous individuals have one dominant allele (F) and one recessive allele (f). Because there is at least one dominant allele, the phenotype of the couple is to have freckles.

The last step of DNA replication is when everything is proofread to eliminate mistakes.

That is option A.

DNA replication includes series of processes whereby a cell uses its DNA to make new copies of its DNA in the cells.

There are various steps in DNA replication and the last of the steps is called termination.

In this last step of DNA replication, an enzyme called exonuclease proofreads the newly formed DNA to check, remove and replace any errors.

The stars that are only fusing hydrogen into helium at this time are :

A star fusing hydrogen into helium is categorised as a main sequence star. As a star continues to fuse hydrogen into helium, energy is released in the process and the luminosity of the star increases as well. An example of  a star that has completely fused hydrogen into helium is the sun. A giant red star signifies that the star is out of hydrogen it uses for nuclear fusion.

Hence we can conclude that the stars undergoing  hydrogen fusion into helium are stars 1, 2 and 3

You would be referring to the plant cell.

Answer:

Chloroplasts may be seen on all six sides of a plant cell, which is a three-dimensional entity with typically moderately rounded corners (not in the centre because a big central vacuole fills a very large part of the volume). Chloroplasts are constantly being rearranged by the cell since they are not set in place. Chloroplasts are typically located close to so-called periclinal cell walls, which are oriented in the same 2D orientation as the leaf surface under low light. Chloroplasts seem to "escape" to the anticlinal walls in bright light. Better light harvesting in low light by exposing every chloroplast to light and photoprotection by mutual shading in strong light are likely the fitness benefits provided by this behavior. In the dark, chloroplasts also gravitate toward the anticlinal walls. Thin leaves of submerged aquatic plants like Elodea can be used as microscope specimens to observe chloroplast motions. One can gauge how much light gets through a leaf in land plants. What I just said concerning the top layer(s) of leaves' "palisade parenchyma cells" is accurate. Most of the chloroplasts are found in these cells. Numerous cells in the spongy parenchyma under the palisade layer lack well marked peri and anticlinal walls.

Chloroplasts must reproduce in a manner akin to that of some bacterial species, in which the chloroplast DNA is duplicated first, followed by binary fission of the organelle (a kind of protein band that constricts so that two daughter organelles bud off). As a result of some chloroplast DNA actually being integrated into the plant genome (a process known as endosymbiotic gene transfer), it is now controlled in the nucleus of the plant cell itself.

Answer:

The expected phenotypic ratio for a cross between two individuals that are heterozygous for a given trait is 3:1.

This is referred to the physical characteristics of an organism such as the size, shape etc.

When two heterozygous traits are crossed:

Rr ×  Rr ⇒ RR Rr Rr rr

The ratio is therefore 3:1 of the dominant to recessive phenotype.

Answer:

Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.

Explanation:

Convection currents are movement of fluid as a result of differential heating or convection. In the case of the Earth, convection currents refer to the motion of molten rock in the mantle as radioactive decay heats up magma, causing it to rise and driving the global-scale flow of magma.  The density of a liquid reduces as it is heated. If the liquid is heated far from the surface, such as at or near the bottom of the container, its reduced density is displaced by colder, denser liquid, and the lighter liquid rises to the top where it meets the cooler liquid. The end consequence is that the heat transfer creates a circulation effect up until the boiling point, or the temperature at which all of the liquid is the same. The lesson to be learned from convective heating is to avoid heating liquids traditionally from the surface because doing so will not result in convection currents. The electromagnetic energy from microwaves typically heats from the top down, penetrating just a few millimeters. The movement (agitation) of the water container and the turbulence caused by the boiling surface water turning into steam are what enable heat transmission. It is typical to see superheating with explosive results due to the localized energy absorption by the surface portion of the water, especially if a powdered substance is introduced to the microwaved water. When the powder is mixed with hot water, nucleation sites are created, which might result in a quick ebullition of boiling water.

The biological process of sexual reproduction requires the input of genetic material from many people. When a flower self-pollinates, for example, the term "individual" might refer to gamete cells developing as a single physical or even genetic organism. I don't want to substitute the word "cell" for "person," either, as that would eliminate instances of acellular biologic entities that reproduce, like viruses. When a piece of a chromosome from one bacterium is injected into another, it recombines and reproduces there, with or without sporulation, which is one instance of what I consider sexual reproduction but which not all viewers would. My notion just requires some genetic material, even in the form of an episome, not gametes. Asexual phases are included in nearly all forms of reproduction, but I regard all of them to be a part of sexual reproduction when they take place throughout a life cycle that also contains an obligatory sexual phase. Brewer's yeast serves as an illustration of the distinction I make because either the diploid or haploid stage, which could be classified as a gametophyte or sporophyte, can be maintained through an infinite number of mitoses. As a result, I consider vegetative propagation to be asexual reproduction.

Now that you have the difference compare the similarties.

Answer:

The liquid in the kettle will be simmering if it is just below the boiling point. The liquid will be hot, but not boiling, and there will be bubbles rising to the surface.

Explanation:

As a greenhouse gas that absorbs heat, CO2 raises the temperature of the atmosphere. We refer to this as global warming. The glaciers will melt more quickly as the world's temperature rises, raising sea levels and bringing on disaster. More power is consumed for air conditioning as the temperature rises, which further raises the air's CO2 level.

Since coal is the primary fuel utilized in the creation of power. This creates a vicious cycle.

Based on the carbon cycle simulation model, what happens when you increase plant biomass is that atmospheric CO2 decreases. because in the cellular respiration of the plants they will consume more carbon.

Plants, through the process of respiration, also absorb carbon dioxide and release oxygen unlike animals. The carbon deposited in the soil can undergo alterations, turning into fossil fuels such as oil and natural gas, in addition to forming diamonds, graphite and coal mines, among others.
