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.
Answers
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.
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
Answers
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
The skin cells of an organism are analyzed and cells identified in G1 and have an average of 12 picograms of DNA. In the same organism a cell from gonadal tissues is identified and that single cell contains 6 picograms of DNA. Given this information, which of the following is true about the single gonadal tissue cell with 6pg of DNA?
1. The cell is at the beginning of Prophase I.
2. The cell has already completed meiosis.
3. The cell is not dividing (is in interphase).
4. The cell contains unduplicated chromosomes.
Answers
Answer:
El Rasho Macuin
Explanation:
The statement which is true about the single gonadal tissue cell with 6 picograms of DNA is that the cell has already completed meiosis. So, the correct option is B.
What do you mean by DNA?It is a complex molecule that contains all the information necessary to build and maintain an organism. It stands for Deoxyribonucleic acid. It is considered the genetic material in most organisms.
The skin cells in the G1 phase have an average of 12 picograms of DNA. As the amount of DNA in the G1 phase is 2C, hence 2C = 12 pg of DNA.
Now in the same organism, a cell from gonadal tissue is identified and that single cell contains 6 pg of DNA, which means, the amount of DNA is 6 pg that is C. Therefore, after the completion of meiosis, the cell contains half the amount of DNA as compared to the parent cell in G1.
So, Amount of DNA = C = 6 pg.
Therefore, the statement which is true about the single gonadal tissue cell with 6 picograms of DNA is that the cell has already completed meiosis.

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.
Answers
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.

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
Answers
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

Answers
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.

Evergreen broadleaf trees, along with abundant rain, warm temperatures, and consistent day length, characterize the _ biome.
Answers
Answer:
Rainforest biome (tropical rainforest)
Explanation:
The characteristics of the tropical rainforest biome are:
Located in humid and warm regions of equatorial climate.Medium temperature among 18 and 30 ºCAnnual precipitation is around 1000 and 8000 millimeters. Precipitation levels are never inferior to 1500 mm. There is no dry season, or if there is, it is too short. There is no hydric deficit. Fanerophic species dominate in this biome. Evergreen tall trees might reach up to 50 meters in height. They develop dense foliation and branches, becoming a refuge and source of food for many species. Vegetation does not need to develop strategies for surviving the dry season. Instead, they need to develop strategies for competing for light and nutrients. We can find different species of plants such as epiphytes, lianas, stranglers, aerial-rooted pants, tabular-rooted plants, among other vegetation forms. Tropical and subtropical rainforests might differentiate from each other in latitude and seasonality. Tropical rainforests might be found in latitudes of the Capricorn and Cancer tropics. From cero to ten degrees latitude. They are in America, Africa, and Asia continents. It is the biome with the greatest biodiversity on the planet. Rainforests have an extraordinary richness of animals and plants.

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.

Q.Why are some diabetes patients treated by giving insulin injections ?
Q. The gap between two neurons is called ------.
Answers
➜ The insulin hormone controls the metabolism of sugar. When pancreas does not produce or secrete sufficient amount of insulin into blood, then the sugar level in the blood rises. Therefore, the patient excreates sugar (glucose) in urine, feels excessive thirst and also urinates excessively. The people having severe diabetes are treated by giving injections of insulin.
➜ Synapse.
Insulin injections are given to individuals suffering from type 1 or type 2 diabetes. It is used when oral medication becomes ineffective. Insulin injections work by helping to move sugar from the blood into the body's cells. Moreover, it also inhibits the liver from producing more sugar.

How would the geneticist learn this type of information about the child's genome?
Answers
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.

Why is the 3-dimensional shape of a macromolecule (ex: protein) important to know from the perspective of understanding
the molecular basis of human disease? 2 pts
A/ Mutations in genes that cause a change in amino acid primary sequence can cause a change in the protein's function in a
cell. For example, it can cause the protein to mislocalize; the protein is now recruited to a specific site in the cell, like the
nucleus, where it can cause cellular dysfunction.
B/ If the protein is an enzyme, the 3-dimensional shape of the active site can be altered and decrease the rate of a reaction that
is catalyzed by that enzyme.
C/ If the protein is an enzyme, the 3-dimensional shape of the active site can be altered and increase the rate of a reaction that
is catalyzed by that enzyme.
D/ Only options A and B may be true.
F/Antions A, B and C may be true.
Answers
Answer:
A, B and C may be true
Explanation:
The three-dimensional structure (3D) of a protein, also known as tertiary structure, is critical to its function. In general, the 3D protein structure consists of alpha-helix and beta-sheets (secondary structures) associated through disordered coiled-coil regions. Genetic mutations may cause modifications in the 3D protein structure by modifying amino acids that are added to the growing polypeptide chain during the process of translation. In consequence, the relationships among amino acids (i.e., the intermolecular attractive forces that hold them together) may also be altered by these mutations. In general, mutations that generate amino acid changes at the active site of the enzyme will have a deleterious effect, thereby decreasing or inactivating protein function. However, there are situations where a mutation may be beneficial and can eventually increase the rate of reaction of a protein.
