Answer:
Answer: D!
Explanation:
A geneticist studied the genome of a child. The geneticist discovered that the genetic
material of the child had three copies of chromosome 13.
How would the geneticist learn this type of information about the child's genome?
Answer:
through karyotyping
Explanation:
The geneticist can learn information about the child's genome through karyotyping.
Karyotyping is a process of analyzing the genome of organisms by first isolating the chromosomes of the organisms after which they are paired and ordered to provide a snapshot of their entire chromosome.
Thus, through karyotyping, all the chromosome sets of organisms can be analyzed and any abnormality detected. Chromosomes that are similar can be further analyzed and discovered to be copies of each other.
Therefore, the geneticist could have learned the information of the child having three copies of chromosome 13 through karyotyping of the child's genome.

In a flower, the anther is attached to filament. What advantage does the filament provide to the anther?
A. The filament elevates the anther to allow for easier transport of pollen by wind or insects.
B. The filament provides the anther with nutrients to produce pollen grains.
C. The filament protects the anther from harsh sunlight and insects.
D. The filament produces a sticky surface to allow the anther to capture pollen.
The correct answer is A. The filament elevates the anther to allow for easier transport of pollen by wind or insects.
Explanation
The filament of a flower is the sterile part of the stamen (male organ of the flower) that is located just below the anther. Its function is structural to hold the sling so that it is accessible to insects. The filament is usually cylindrical and fine. Therefore, the correct answer is A. The filament elevates the anther to allow for easier transport of pollen by wind or insects.

Hide Assignment Information Instructions INSTRUCTIONS You are bird hunting moths (both dark and light) that live on trees. As you capture the moths most easily visible against the tree surface, the moth populations change, illustrating the effects of natural selection. In this Lab, you will: Predict the color of moth that will survive better on various colors of tree trunks. Understand how camouflage can promote survival. Explain the process of natural selection.
Answer: The theory of natural selection suggests that some members of the population of species have better advantage of others for survival in terms of better phenotypic traits.
Explanation:
According to the given situation, the moths which have color that remain undetected by me as bird has a phenotypic advantage. As I may not be able to observe them on tree trunk or bark or on leaves I can eat only those moths that can be seen through my eyes. I can capture them easily. Such moths which can change their colors in accordance with the color of the tree can camouflage me easily and I cannot observe them and consume them. This promotes their survival over those detectable moths.

Corona means____ and most human corona viruses cause ____ symptoms in humans. A. Circle, mild B. Crown, major C. Crown, mild
Answer: the answer is c for both
Explanation:
A cleft chin in humans is coded by the dominant allele C. A chin without a cleft is coded by the recessive allele c. A man with a cc allele combination for the trait produces a zygote with a woman with a Cc allele combination for the trait. Which allele combinations could occur in the zygote?
Answer:
The allele combinations are: Cc, cc, Cc, cc
Phenotypically there is a 50% chance that the child will be born with or without the cleft
The allele combinations that could occur in the zygote is Cc or cc.
What is an allele combination?An identification of the specific alleles found at each of the relevant mouse loci on the two homologous chromosomes (i.e., all allele pairs of a genotype). One or more allele pairs can make up an allele combination.
Genetic linkage is the capacity of a chromosome to transmit alleles that are near to one another as a whole unit through meiosis. Inheritance of traits is also understood by this principle. It is useful in locating the genes that are in charge of characteristics and diseases.
The person is homozygous for the allele if the two alleles are the same. The person is heterozygous if the alleles are different.
Therefore, the zygote may include the allele combinations Cc or cc.

Explanation:
Consider a breeder that mates two heterozygous black Staffordshire bull terriers over the course of three years. The dam eventually produces 16 puppies: 11 are black like the parents, 4 turn out white, and 1 turns out gray colored. As a genetics student, what do you think of this outcome
Answer:
Different colour occur due to heterozygous nature.
Explanation:
Most of the puppies just like parents because the black colour gene or allele is dominant over other colour allele whereas other colour puppies also formed due to presence of heterozygous type of alleles. Other colour occurs due to appearance of recessive allele in the physique of the offspring or formation of hybrids occurs which causes colour other than black and white in the offspring. In the F1 generation all the offspring resembles to the male parent but after this generation some offspring resembles to male, some are hybrids and other resembles to female.
You are a mad scientist tasked with the evil job of designing a novel species. This species will be introduced to an ecosystem
and must cause as much damage as possible. What abilities and characteristics will you give this species to make it
successful? Be sure to explain why you choose each aspect. Explain your choice in 3-5 sentences. (4 points)
Answer: The new animal species I would release into an ecosystem would be aquatic animals. One that could affect the water supply in the ocean, causing the collapse of the ecosystem I place my animal in. My animal would be a shark-like creature of the otodontidae shark family with skin so tough, not even a harpoon could pierce, to protect itself from predators. I would give my animal the immortal ability of a genus hydra so it can never be killed. My species would also release toxic chemicals into the water destroying other living organisms in the water and poisoning any creature that drinks the water. The species would thrive without the need for water or substance like other creatures and have the ability to adapt to any situation or environment so it can survive in any ecosystem I were to place it into.
Novel species are newly designed or discovered species. The organism is altered genetically and is different in some characteristics from its original. I will create an aquatic animal.
How an imaginary novel species can be created?For this imaginary question, I will introduce aquatic species in the ecosystem. As it will affect the aquatic ecosystem of the water and will affect the oceanic life.
I will modify and alter the genes of the piranhas family as they are already very dangerous and any modification in them would create monster species. I will combine some of the genes of the other very dangerous animal with that of the piranhas.
Also, I will combine the ability of regeneration and immortality with the new novel species. I will increase their attacking capability and will add some poisonous chemicals to be released while they hunt to kill their prey.
In addition, I will make them capable to survive in terrestrial places as well so that they can even survive without water.

The light-independent reactions of photosynthesis, also known as the Calvin cycle, must repeat three times in order for a cell to have enough material to construct half a glucose molecule. A variety of molecules are used and produced during this process. Identify the molecules into three categories: molecules brought in and used in three turns of the Calvin cycle, molecules produced during three turns of the Calvin cycle that leave the cycle, and molecules used and regenerated within the Calvin cycle during three turns.
Answer:
- molecules brought in and used in three turns of the Calvin cycle = carbon dioxide (CO2)
- molecules produced during three turns of the Calvin cycle that leave the cycle = Glyceraldehyde-3-phosphate (G3P)
- molecules used and regenerated within the Calvin cycle during three turns = Ribulose bi phosphate (RUBP)
Explanation:
The second stage of photosynthesis, called CALVIN CYCLE, occurs in the stroma of the chloroplast. The processes that occur in this stage can be divided into three stages namely: carbon fixation, reduction and regeneration.
As rightly stated in this question, the calvin cycle must repeat three times in order for a cell to have enough material to construct half a glucose molecule. Hence;
- In carbon fixation, molecules of carbon dioxide (CO2) are brought in and used in three turns of the Calvin cycle. The CO2 combines with a CO2 acceptor called RUBP (ribulosebiphosphate) to produce PGA (3-phosphoglycerate).
- In the reduction stage, PGA is reduced to Glyceraldehyde-3-phosphate (G3P). This G3P molecule is produced during three turns of the Calvin cycle and leaves the cycle to be used to form glucose.
- In the regeneration stage, remaining molecules of G3P are used to regenerate RUBP in order for the cycle to continue. Hence, RUBP molecules are used and regenerated within the Calvin cycle during three turns.
In fruit flies, curved wings (w) are recessive to the dominant straight wings (W), and ebony body (b) is recessive to the dominant gray body (B). A fly that has curved wings and ebony body is crossed with a fly that has straight wings and gray body. Of the offspring there were approximately equal numbers of straight gray, straight ebony, curved gray, curved ebony. What are the genotypes of the parents and offspring
Answer:
The correct answer =
parents : WwBb x wwbb
offspring :
WwBb, Wwbb, wwBb, and wwbb
Explanation:
It is given that the straight wings (W) is dominant over curved wings (w) and the ebony body (b) is recessive to the dominant gray body (B) and there is a cross between curved wings and ebony body and straight wings and gray body is made. The phenotypic ratio is: 1:1:1:1 for the four different phenotypes straight gray, straight ebony, curved gray, curved ebony.
It is not given the genotype of parents, however, for the curved and ebony fly, it is clear that both alleles are recessive as recessive alleles only appear in absence of the dominant allele of the trait.
For another parent, the possible genotypes can be WWBB or WwBb, however in the case of WWBB the phenotypic ratio would not be equal therefore,
crossing WwBb x wwbb
This can be represented in the form of a punnett square as below:
wb wb wb wb
WB WwBb WwBb WwBb WwBb Straight wing, Gray body
Wb Wwbb Wwbb Wwbb Wwbb Straight wing, Ebony body
wB wwBb wwBb wwBb wwBb Curved wing, Gray body
wb wwbb wwbb wwbb wwbb Curved wing, Ebony Body
The phenotypic ratio is: 1:1:1:1 for the four different phenotypes
Environmental scientists calculating pollutant half-lives often define a transport rate constant that is analogous to a reaction rate constant and describes how a pollutant moves out of an ecosystem. In a study of the gasoline additive MTBE in Donner Lake, California, scientists from the University of California, Davis, found that in the summer the half-life of MTBE in the lake was 26.01 days. Assume that the transport process is first order. What was the transport rate constant of MTBE out of Donner Lake during the study
Answer:
k ≈ [tex]2.7 *10^{-2} d^{-1}[/tex]
Explanation:
For a first order reaction
Half life ( [tex]t_{1/2}[/tex] ) = 0.693 / k
k = rate constant
[tex]t_{1/2}[/tex] = 26.01
hence k = 0.693 / ( 26.01)
k ≈ 2.7 * 10^-2 d^-1
This is a detailed simple solution as required
