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.
How does elevation affect climate?
A. It determines whether winds will blow inland bringing moist air, or towards the ocean bringing dry air.
B. It determines how much solar energy an area receives and thus how hot it will be.
C. It determines how dense the air is, and how much heat energy the air can hold.
D. It determines whether winds will blow inland bringing moist air, or towards the ocean bringing dry air.
Altitude affects weather determines how dense the air is and how much heat energy the air can hold.
Option C is the correct one.
What is the relationship between authority and climate?The relationship between climate and altitude is manifested through variations in atmospheric pressure and temperature. Although higher locations are closer to the sun, they tend to receive less heat, becoming colder, in addition to having a smaller thermal amplitude (temperature variation).
With this information, we can conclude that Higher elevations cause temperatures to drop because the higher up in the atmosphere you go the colder it gets due to air pressure in turn causing precipitation to freeze creating snow.

compare and contrast sexual and asexual reporduction
Difference:
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.

Why are chloroplasts more on one side of a cell than the other
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.
How did plant cells incorporate chloroplasts in their DNA?
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.
Changes in water temperature affect the density of the water. Water density is important for deep ocean currents that move water around the oceans. With increasing greenhouse gases in the atmosphere, the ocean is absorbing more and more heat. The Beaufort Gyre is a circular current in the Arctic. Which of the following is the most reasonable hypothesis as to what would happen to the Beaufort Gyre if the oceans keep warming?
The water would get warmer and would not sink to the bottom, and therefore disrupt the worldwide currents.
The water would get colder and sink to the bottom, then take longer to warm up disrupting currents.
The water would change temperature and begin to circulate in the opposite direction.
The water would get much warmer and cause part of any nearby continental ice sheet to melt.
Answer:
The water would get warmer and would not sink to the bottom, and therefore disrupt the worldwide currents
Explanation:
the warmer water is less dense than the colder water and would not sink, which would interrupt the natural currents with extra external heat added by global warming

How do convention currents work
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.
