If a red-eye female fly is crossed with a red-eye male fly, could they produce offspring with white eyes? Briefly explain your answer. Your answer must include a Punnett square that proves your answer.
If the red-eye parents are homozygous, no. But if the red-eye parents are heterozygous, yes.
Monohybrid crossingWe are assuming that the red-eye trait is dominant over the white-eye trait. If two red-eye parents are crossed with one another, whether they could produce white-eye offspring would depend on the zygosity level of the parents.
Assuming that red-eye is R and white-eye is r. If the two parents are homozygous red-eyed, their genotypes would be RR. Crossing the two:
RR x RR
RR RR RR RR
All the offsprings would be RR and there is a zero chance of producing a white-eye offspring.
Now, assuming that the two parents are heterozygous:
Rr x Rr
RR Rr Rr rr
Both RR and Rr are red-eyed while rr is white-eyed. The Punnet's square for the cross can be found in the attached image.
In other words, it will only be possible for the two red-eye parents to produce white-eye offspring if they are both heterozygous. Any other genotype will give a zero chance of white-eye offspring.

Why are Canada’s Evergreen Forests considered “Earth’s Northern Lungs”? (think about the photosynthesis equation)
Answer:
Although trees have responded to global warming in the past‐ to temperatures higher than they are now- the rate of change predicted in the 21st century is likely to be unprecedented. Greenhouse gas emissions could cause a 3°-6°C increase in mean land surface temperature at high temperatures and temperatures latitudes. Despite this, few experiments have isolated the effects of temperature for this scenario on trees and forests. This review focuses on tree and forest responses at boreal and temperate latitudes, ranging from the cellular to the ecosystem level. Adaptation to varying temperatures revolves around the trade- off between utilizing the full growing season and minimizing frost damage through proper timing of hardening in autumn and dehardening in spring.

how do eumelanin and pheomelanin affect our skin color?
Answer:
There are two types of melanin--eumelanin and pheomelanin. In general, the more eumelanin in your skin, the darker your skin will be. People who make more pheomelanin than eumelanin tend to have lighter skin with freckles. Like many other traits, the amount and kind of pigment in your skin is controlled by genes

which 3 reactions form atp?
Answer:
Answer below
Explanation:
The eight steps of the citric acid cycle are a series of redox, dehydration, hydration, and decarboxylation reactions. Each turn of the cycle forms one GTP or ATP as well as three NADH molecules and one FADH2 molecule, which will be used in further steps of cellular respiration to produce ATP for the cell.
1.Gravity is
found only between the earth and the moon
not found in space, but is only found on earth
a pulling force that exists between all objects in the universe
a force that pushes objects away
2.Which statement is true about a planet’s orbital motion?
Orbital motion results when the object’s forward motion is balanced by a second object’s gravitational pull.
Orbital motion is limited to the moons of the planets and the planets in our solar system.
Orbital motion cannot be achieved with man-made objects.
Orbital motion only occurs when forward motion exceeds the gravitational pull.
3.How does distance affect the gravitational force?
The gravitational force decreases as distance increases.
The gravitational force is not changed by distance.
The gravitational force changes unpredictably with distance.
The gravitational force increases as distance increases.
4.As mass increases, the gravitational force
changes unpredictably
decreases
stays the same
increases
Answer:
The moon's gravitational pull on the Earth is the main cause of the rise and fall of ocean tides. The moon's gravitational pull causes two bulges of water on the Earth's oceans—one where ocean waters face the moon and the pull is strongest and one where ocean waters face away from the moon and the pull is weakest.

consider the endosymbiont theory and the fact that chloroplasts contain dna molecules. given that chloroplast DNA has genes,
Answer/Explanation:
The endosymbiotic theory is the idea that eukaryotic cells evolved from the fusion of two prokaryotic cells that formed a symbiotic relationship, with one living inside the other.
An endosymbiont is one organism that lives inside another one.
The existence of mitochondria and chloroplasts, which contain their own DNA and ribosomes, supports this theory. Mitochondria are chloroplasts were once free-living organisms, they were prokaryotes that ended up inside of other cells.
Mitochondria and chloroplasts have genes that are very similar to the genes of prokaryotes. Their membranes look like the prokaryotic cell membrane, and they divide in similar ways.

Hope this helps!!!A biochemist extracts a molecule from a cell. This molecule catalyzes a chemical reaction. To what class of molecules does it belong?
A. Proteins
B. Carbohydrates
C. Lipids
D. Nucleic acids
Answer:
proteins create enzymes which speed up reaction
Enzymes are the molecules that catalyze biological reactions, while a catalyst is a material that aids in the occurrence of a chemical reaction, hence option A is correct.
How do enzymes catalyze chemical reactions?The crucial function of decreasing the activation energy of chemical events inside the cell is carried out by the majority of enzymes, which are proteins.
Enzymes are biological catalysts that significantly speed up reaction rates and have the propensity to be particular about particular reactants and products, a substrate is a term for the reactant in an enzyme-catalyzed process.
Proteins are called enzymes to catalyze biological reactions that would not occur without them. For chemical reactions like digestion and cellular metabolism, these enzymes are necessary.
Therefore, since enzymes are a specific type of protein that catalyzes chemical events inside cells, they are excellent therapeutic targets, hence option A is correct.

Which letter marks the zone of inhibition?
Answer:
A. B
Explanation:
"B" as labelled in the above is the zone of inhibition.
The Zone of Inhibition is actually a test which is used to assess antimicrobial activities of a material or solution in relation to an micro-organism as a target. It is also known as Kirby-Bauer Test. It measures the antibiotic resistance and also used to inhibit microbial growth.
At the Point B, microbes can not grow in there; they are inhibited.
In the test, if bacterial strain or any other strain is susceptible to the antimicrobial agent, a zone of inhibition appears. If it shows resistance to that agent, then no zone is evidential.
What does the study of embryology tell us about evolution?
Answer:Embryology, the study of the development of the anatomy of an organism to its adult form, provides evidence for evolution as embryo formation in widely-divergent groups of organisms tends to be conserved. ... Another form of evidence of evolution is the convergence of form in organisms that share similar environments.
