Answer:
Explanation:
The rate of pollination in the field (near the pond with no fish) will decrease exponentially. Because, as the fish population is removed from that ecosystem, the population of dragonflies and larva increases without check because, fish feeds on the dragonflies larva and kept there population in check. Due to this, the population of bees and other pollinators population decline becuase, they are major food source of dragonflies.
Honeybees are the keystone species because it's absence will lead to major changes in the ecosystem.

Can two O blood type parents have a non-O blood type child? Explain your reasoning.
Answer:
But now, the Punnett square looks different! Even though both parents still have blood type A, Dad can pass on either his A or his O gene version. Mom can also either pass on her A or her O. Because of this, you can see that there's 1 in 4 or 25% chance for a child to have OO, or blood type O

Explanation:
You are exploring a rather inhospitable planet, which has seas that are somewhat hydrophobic in nature. Surprisingly, there are living organisms in the seas whose cytoplasm is hydrophobic to a similar degree. These organisms have membranes made primarily of phospholipids arranged in a bilayer. What is the most probable orientation of these phospholipids A.hydrophobic tails facing towards the middle of the bilayer and the hydrophylic heads facing outward
Answer:
The correct answer would be: hydrophilic heads of the phospholipids face toward the middle of the bilayer with the hydrophobic fatty acid tails facing outward
Explanation:
In normal cases on earth, the lipid bilayer is arranged in a way that the hydrophilic head is present both inside and outside whereas the hydrophobic tail is present in the middle.
But in this case, the seas shows hydrophobic nature it can be predicted that the living organism whose cytoplasm is hydrophobic to the same condition that to interact with the environment the phospholipids bilayer arranged as the polar heads on middle while hydrophilic head on its inside and outside
Producing disposable grocery bags consumes resources. Recycling disposable bags is a solution that can recover some of the resources used to make new bags. Which of the following behaviors could further refine the solution? O A. Reusing bags whenever possible O B. Using only nonrenewable materials to make new bags O c. Using two bags at once so that they do not break D. Disposing of bags by burning them
Answer:
A
Explanation:
it is the best choice for the environment
Reusing bags whenever possible will be sustainable solution for difficulties in recycling and production of the grocery bags. So, option A is correct.
What is meant by biodegradable materials ?Biodegradable materials are defined as the substances that can be decomposed by bacteria and other microorganisms, so that pollution is avoided.
Here,
It is said that, producing disposable grocery bags consumes resources.
So, the sustainable method for avoiding these complications and difficulties in finding the more amount of resources, is the method of recycling the disposable bags.
The recycling method can help us to recover some of the resources and thus the over consumption of the natural resources can be reduced. But sometimes, the process of recycling is also inconvenient for the environment.
Since, the use of grocery bags in our daily life is in a huge number, the recycling of all these bags are not easy.
Even though the grocery bags are disposable, but the recycling method for the whole is somewhat difficult. So, as the most sustainable solution for this, introduction of reusable bags will be more convenient.
Therefore, use of reusable grocery bags will solve the problem of recycling and production, to an extend.
Hence,
Reusing bags whenever possible will be sustainable solution for difficulties in recycling and production of the grocery bags.

Where in the plant are the hormones auxins produced? (Select all that apply.)
A. stems
B. roots
C. chloroplasts
D. seeds
E. leaves
F. fruits
Answer:
Stems and root
Explanation:
Auxins facilitate stem elongation while inhibiting axillary bud formation, ensuring apical dominance. The root, branches, and stem and tip all contain them. Hydroxy Acetic Acid is a perfect example. Auxin is indeed a growth hormone that facilitates cell elongation and is formed in the stem tip.
In stems, roots, leaves and fruits, hormones auxins are produced. Therefore, the correct options are A,B,E and F.
Plants' apical meristems are where auxins are predominantly made, and they are then carried by the plant's vascular system. Although there are synthetic auxins available for agricultural use, indole-3-acetic acid (IAA) is the predominant naturally occurring auxin in plants. Auxins are crucial hormones for plant growth and development, to sum up. They control a variety of tropic responses as well as cell elongation, apical dominance, root growth, phototropism, fruit development, and leaf abscission. Gaining knowledge of auxin regulation and function can help us better understand plant biology.
Therefore, the correct options are A,B,E and F.

All organisms' cells contain DNA. Every organism's DNA is made of nucleotides. Although, the four species on this phylogenic tree are different, which components of their DNA are the same? Species = Human , Chimp, Gorilla, Orangutan
A = sugar deoxyribose and the base thymine.
B= sugar deoxyribose and the base uracil.
C= sugar ribose and the base thymine
D= sugar ribose and the base uracil.
Answer:
A = sugar deoxyribose and the base thymine.
Explanation:
DNA is the storage molecule of the genetic information in almost all cells of living organisms. DNA is one of the two types of nucleic acids, a biological polymer made up of monomeric units called NUCLEOTIDES.
Nucleotides of a DNA are composed of three major substances that make up its structure. The three components are; a pentose sugar (deoxyribose), phosphate group and nitrogenous bases, which can be Adenine, Thymine, Guanine and Cytosine.
Based on this question, although the following four species are different: Human , Chimp, Gorilla, Orangutan, but their DNA contains the following same components; sugar deoxyribose and the base thymine. This is because all DNA has deoxyribose instead of ribose and thymine instead of uracil.

In mice, coat color is determined by 2 epistatically interacting genes. Mice with genotype aa for the first gene are always albino; otherwise, they can produce melanin. If they produce melanin (have at least 1 A allele), then their coat color is determined by a second gene. In particular, if their genotype at this second locus is bb, then they are black. Otherwise, they are agouti (brown). For example, a mouse with genotype Aabb is black, but one with genotype aabb is albino; genotype AaBb produces an agouti mouse. What is the phenotypic ratio of the following cross: aaBb x Aabb?
Answer:
The phenotypic ratio is 7:4:5
Explanation:
To discover the phenotypic ratio between the aaBb and Aabb crossing, it is necessary to fill the Punnet Square for dihybrid crosses, which has 16 houses. Dihybrid crosses are those that present a genetic inheritance confirmed by two characteristics, as is case of the mouse coat shown above. In this case, instead of two alleles per characteristic, we will have four alleles.
The Punnet Square for the crossing AaBb x AaBb, is shown in the image shown below. To form the first row and the first column of the square, we must determine the pair of alleles that each parent has. These pairs are formed by the first "A" with the first "B," the first "A" with the second "B," the second "A" with the first "B" and the second "A" with the second "B" . " For example, in parent AaBb we will form pairs of alleles AB, Ab, aB and ab. We will do this with the two parents. Then we combine the pairs to form the offspring, as shown in the figure.
In order to determine the phenotypic ratio of the offspring, we must pay attention to the information presented in the question. The question states that the Agouti genotype is determined by the presence of the Allelo B (uppercase), for this reason, we must count all the members of the offspring that have at least 1 letter B (uppercase) in their genotype. At the end of the count, you will notice that there are 7 individuals of the offspring with agouti fur.
The black coat is determined by the presence of allele A (uppercase) and absence of allele B (uppercase). In this case, we must count all the individuals who have the Allele A and have the allele b (lower case) in place of B. Upon finishing the count we will notice that there are 4 individuals with the black coat.
The white coat is only seen in individuals who have the aabb alleles, since this color is the recessive characteristic. In this case, we must count all individuals who have this genotype. At the end of the count, we will notice that there are 5 individuals with white coats.
In this case, the phenotypic ratio refers to the number of individuals of each color that is 7: 4: 5.

Explanation:
In many bird species, males are brightly colored, while females are dull in color. How might this adaptation become more common over time?
Answer:
Through breeding over time with the lighter colored males, The lighter color in the males feathers help find out which male is better compared to the others, in other words the brighter colored males have a higher chance at getting the females, and eventually if these males have a higher chance at successfully mating the dominating colors of the males will be passed down to the future offspring, making it more common for birds to have a more colorful or lighter pigment in male species, or just in general in both genders, depending on the way the genes are carried from parent to offspring.
