Allele for solid green fruit => (G)
Allele for striped fruit => (g)
The cross between the two plants is shown below:
(GG) × (Gg)
Offspring => (GG), (Gg), (GG), (Gg)
Since G (allele for solid green fruit) is dominant over g (allele for striped fruit), therefore,
We all the offspring in the F1 generation would be all waterlemons of solid green fruits.
Therefore, % of offspring of this cross that will bear striped watermelon would be 0

When the rate of transpiration exceeds the rate of water absorption, the leaves wilt
and droop while the stem remains upright.
Explain why the stem remains upright when the leaves wilt.
Answers
Answer:
When the soil of a plant runs too low on available water, the water chains in the xylem become thinner and thinner due to less water. When this happens, the plant loses its turgidity and begins to wilt. Low soil moisture is often the reason this happens but other factors play a role as well.

g A gene has two alleles a and b. In the gene pool, the a allele accounts for 70 percent of the alleles at this locus. If the population is in Hardy-Weinberg equilibrium, what percentage of the population is heterozygotes with respect to this locus
Answers
Answer:
42%
Explanation:
When allele frequency and genotype frequency stay constant in a randomly mated population, the population is said to obey Hardy Weinberg equilibrium.
By using Hardy Weinberg Equilibrium for the given information; we have the following equations:
p + q = 1; &
[tex]\mathbf{p^2+2pq+q^2 =1 }[/tex]
Here; allele a = p
allele b = q
the heterozygous allele ab = 2pq
Since; a = 70%, then the percentage of allele a = 0.70
Now;
p + q = 1
0.7 + q = 1
q = 1 - 0.7
q = 0.3
So, allele b = 0.3
Finally, to determine the percentage of the heterozygous population:
2pq = (2 × 0.7 × 0.3)
= 0.42
= 42%

Which mating of four-o'clock plants would produce progeny that were either green, variegated, or white
Answers
Answer:
variegated female x green male
Explanation:
The four o'clock (Mirabilis jalapa) plant is a common ornamental species of Mirabilis (clade Angiosperms, flowering plants) whose leaf pigmentation is a well-known case of maternal inheritance. Moreover, chloroplasts are organelles that have their own genome which follows a maternal inheritance pattern in the majority of plant and animal species because they are contained in the cytoplasm (i.e., chloroplast DNA is inherited only from the mother because only the maternal cytoplasm persists after fertilization). Thus, chloroplast DNA has an inheritance pattern that challenges Mendel's Laws of inheritance (i.e., distinct from nuclear DNA). In the case of the four o'clock plant, the genes responsible for leaf color are located in the chloroplast genome and therefore these genes are transmitted from the female parent to the progeny. In this case, the leaf variegation is caused by two different types of chloroplasts that are inherited from the mother: normal green chloroplasts and defective chloroplasts (without chlorophyll pigment).

Which two labels should be switched?
Answers
A student has labeled this diagram of Earth's layers, but two of the labels that are incorrect is asthenosphere and crust. The asthenosphere have to switch with crust in labelling pattern.
which are the three layers of the earth?Our earth is made up of several layers which are furthur divided into the three types: Crust, mental and core.Crust layer is the most uppermost layer of earth which acts like skin of the earth, it divide into the many plates which are smooth and build up pressure.
Mantle is the largest layer located under the sima composed of very dense and hot rocks. This layer under heavy weight pressure flows like asphaults. Thier movement is responsible for the plates of earth movement.
Core consist of very hot metals and all metals present in this layer is present in the form of liquid.outer core is consisted of nickel and iron in liquid from. Inner core is mostly consist of iron and it is solid in nature.
Asthenosphere is the basically the zone of the earth's mantle. it is malleable and keep the earths plate present in crust lubricated.it is present just below. it is present above the mantle and below the crust.Crust acts like the outer skin of the earth.
Crust is prior to the asthenosphere in earth layer sequence.

Under which of the following circumstances would a DNA microarray be useful? Multiple Choice It would enable a researcher to determine the differences in gene expression between cell types. Researchers are trying to determine if an individual has inherited a genetic disease from their parents. It would enable doctors to determine which genes are responsible for producing diseased tissue in an individual. All of these are circumstances in which a DNA microarray would be useful. None of these are circumstances in which a DNA microarray would be useful.
Answers
Answer:
The correct answer is ''All of these are circumstances in which a DNA microarray would be useful.''
Explanation:
A DNA microarray is used to determine the complete genetic expression of a tissue at a given time. DNA microarrays is one of the most important applications for the information obtained from the systematic sequencing of complete genomes. They consist of a membrane, which can be made of nylon, silicone or a simple glass slide. The DNA of many genes, arranged according to a specific pattern, is immobilized on this membrane. These DNA fragments, which are known as probes or oligos, are arranged in microscopic spots. Microarray technologies are used in research at the molecular level, they allow the study of simple changes in the DNA sequence and mutations in complex genes that are associated with a specific disease, helping to diagnose diseases.

The concentration of potassium in human blood is extremely important for a huge array of functions that are vital to survival, and research has found that individuals whose potassium levels are regularly too high or too low have a higher mortality rate than individuals with normal levels. Given this finding, which feedback mechanism is most likely involved with potassium homeostasis
Answers
Answer:
negative feedback
Explanation:
The ability that cells have to adapt to their environmental conditions is fundamental for their survival. In cell biology, negative feedback is considered to be the predominant feedback mechanism. Negative feedback occurs when the increase in the concentration of a particular molecule leads to its subsequent decrease (or the decrease of another molecule), therefore bringing the system to the initial state. Thus, negative feedback leads the output of the system (in this case, the cell) to be lessened in order to stabilize the system (i.e., previous homeostasis or equilibrium of the system). Potassium is the most abundant positive ion (proton) in any type of cell, being fundamental for many diverse cellular processes such as, for example, regulation of the cell volume and protein synthesis. Potassium homeostasis is controlled by a negative feedback loop in which participate proton transport proteins and a bicarbonate buffer system that serves to counteract low external potassium levels.

C. All species have their own specific body structures, so it is a coincidence that this trilobite and blue crab each happen to have the biramous limb structure.
D. The trilobite and blue crab are different species, so they must not share an ancestor population. They inherited their biramous limb structure from separate ancestor populations.

Answers
Answer:
I think the answer is b
Explanation:
b The trilobite and blue crab both share the same ancestor population that had a biramous limb. They inherited this structure from the ancestor population. c All species have their own specific body structures, so it is a coincidence that this trilobite and blue crab each happen to have the biramous limb structure.
A biramous limb is one that divides into two branches, each of which is made up of a series of segments attached end-to-end. Both species have biramous limbs as the trilobite and blue crab are different species, so they must not share an ancestor population. They inherited their biramous limb structure from separate ancestor populations, i.e., option D.
What are ancestors?An ancestor is a parent or the parent of an antecedent, also recognized as a forefather, fore-elder, or forebear.
An ancestor is from whom organism is descended In law, the person who has inherited an estate.
As in the given scenario, fossil trilobite and this living blue crab both have a limb structure called a biramous limb as the trilobite and blue crab are different species, so they must not share an ancestor population.
They inherited their biramous limb structure from separate ancestor populations.
