what is the importance of autotrophic organisms for other organisms?
Answer:
the importance of autotrophic organisms with respect to energy flow and nutrient cycling in ecosystems. Primary producers usel solar or chemical energy to manufacture their own food and they use this energy through cellular respiration and growth and reproduction--energy used for NPP.
What common features do eukaryotic mRNA share? Please use one of these features to describe how you can isolate eukaryotic mRNA from the cell extract. (limit your answers in 4 lines)
Answer:
A common feature in mRNAs that allow extraction from the cell is the 5' cap region which has a Guanine nucleotide attached to the mRNA in an atypical five prime to five prime triphosphate linkage.
Explanation:
The 5' cap structure serves to protect the mRNA against damage from RNA phages and an extraction protocol an be used to isolate the mRNAs from the cells. Reagents such as Dichloromethane, sodium hydroxide and diethyl ether in aqueous solution helps separate the organic layer, a silica-gel column can be used to further isolate the mRNAs
some flowering plants are pollinated by honeybees at some time in the past honeybees evolved the ability to see ultraviolet radiation some flowers have evolved to produce ultraviolet markers on their pedals that direct honeybees to the reproductive parts of the flower what is this example of?
Answer:
Coevolution
Explanation:
Coevolution refers to the mechanism where two or more species interact by the evolutionary process of natural selection. The mechanism of coevolution was mentioned by Darwin to explain the existing interactions among flowering plants and insects, in a similar manner to the example above described. Examples of coevolution also include the race between pathogenic organisms and the immune responses or the emergence of resistance in pathogens that affect genetically modified (originally resistant) crop varieties.

The correct answer is A.2,916 m3.
What is circular cylinder?A circular cylinder is a three-dimensional geometric shape that consists of two parallel circular bases and a curved lateral surface that connects the two bases. The shape of a circular cylinder resembles a can or a pipe, and it is a common shape in everyday objects and engineering applications.
To calculate the volume of a right circular cylinder with a radius of 2 meters and a height of 9 meters, we need to plug in the given values into the formula: Volume = πr2h. Since π is a constant that is roughly equal to 3, we can use 3 in place of π.
Therefore, the volume of the cylinder is equal to 3 x (2 meters)2 x (9 meters), which is equal to 2,916 m3.

after staining what should be the color of vegetative cells
Answer:
See below
Explanation:
As a result of staining the cells, while all of the cells now appear pink, the vegetative cells show some area that has not been stained pink (perhaps because they did not take up the dye). This is a clear indication that they are in their vegetative state as opposed to the normal cell growth stage as demonstrated by the remainder of the cells.

Answer:
D. Haploid daughter cells with unique chromosomes.
Explanation:
This is because during Mitosis 2 the sister chromatids within the two daughter cells separate, form four new haploid gametes.
D. Haploid daughter cells with unique chromatids are responsible for creating.
What does meiosis 2 create?Meiosis II starts with two haploid parent cells and ends with four haploid daughter cells, maintaining the number of chromosomes in each cell.
What are the products of meiosis and meiosis II?Thus, the products of meiosis II are four haploid cells that contain a single copy of each chromosome. In mammals, the number of viable gametes obtained from meiosis differs between males and females. In males, four haploid spermatids of similar size are produced from each spermatogonium.

Come up with your own story of a trophic cascade, describing how the organisms occupying the different trophic levels would be affected
Answer:
The leafhoppers eat plant tissues and, at the same time, they are eaten by spiders that are the food of large lizards. Finally, these lizards are the food of birds that are eaten by snakes.
Explanation:
The food chain starts with primary producers such as plants and algae (i.e., level 1), then goes through herbivorous species including insects and fish (level 2) and finally ends with carnivores such as rodents, snakes and hedgehogs (levels 3, 4 and sometimes 5, which depends on presence of larger predators). Thus, the trophic levels are represented by the number of steps of the food chain. In an ecosystem, the organisms can also be classified according to the mode of obtaining the food in producers (autotrophs), consumers (heterotrophs) and reducers (detritivores).

Explain why chemogenetic based methods of regulating cellular signaling result in poor temporal control of biochemical pathways relative to optogenetic based methods.
Answer:
They use different detecting methods to assess neuronal circuits
Explanation:
Chemogenetics is a technique widely used in neuroscience research to explore signaling interactions by means of genetically modified receptors capable of interacting with small molecules. Chemogenetics was first used to determine the function of the chalcone isomerase gene by inducing mutations that altered its substrate specificity. On the other hand, optogenetics is a bioluminescence-driven genetic technique used to control genetically modified neurons that express light-gated ion channel genes. This technique is also used to monitor neuronal networks. In consequence, optogenetic and chemogenetic techniques have recently been combined in order to analyze neuronal circuits, it by analyzing the same actuator molecule.
ions but you do not want to increase the volume of the blood by reabsorbing large amounts of water from the filtrate. Assuming the aldosterone and ADH are both present, how would you adjust the hormones to accomplish the task
Answer:
Aldosterone and ADH are part of the renin angiotensin aldosterone system, this system is a system regulated by the kidney and lungs to be able to raise blood pressure.
Explanation:
This system is a retainer of liquids and water, to increase the blood volume of our body, in this way arterial hypotension is compensated.
Another mechanism with which blood volume can be increased is with the stimulation of thirst, and the need to ingest a liquid because of the dry mouth that our central nervous system perceives.
Both mechanisms prevent hypotension and dehydration.
Which of the following phenotypic classes reflect offspring that were generated as a result of a recombination event?
a. vestigial wings, red eyes
b. vestigial wings, purple eyes
c. full wings, red eyes
d. full wings, purple eyes
Answer:
The correct options are: A " vestigial wings, red eyes" and D "full wings, purple eyes"
Explanation:
female parent: vg+pr+/vg pr
(phenotype - full winged and red eyes)
male parent: vgpr/vgpr
(phenotype - vestigial winged and purple eyes)
Of these traits, vestigial wings and purple eyes are recessive traits. Hence, when a recombination event occurs, the offspring can potentially have a wild type trait paired with a recessive trait.

O Multiple alleles
Chromosomes
O Carriers
Sex linked genes
Answer:
A
Explanation:
Why were the advent of metagenomics, and the application of molecular techniques such as single-cell and next-generation sequencing, important for defining a microbial relationship
Answer:
Based on novel approaches, it has been seen that symbiotic associations prevails between a host and one to thousands of more microbes, which challenges the previous meaning of symbiotic association as one that takes place between the host and a single microbe. It was considered previously that symbiotic association’s takes place only between the pair of single microbe and host.
However, newer approaches has revealed that such kind of association can take place between one microbe and many other hosts. A symbiotic association can take place between microbe-microbe, plants-plants, microbe-plants, and others. However, symbiotic association has never been found to take place between a bacteria and animal host. The symbiotic associations are always not parasitic.

What was an unintended negative environmental consequence of improved technology in agriculture?
A. Farmers went bankrupt purchasing expensive equipment.
B. Modern technology allowed for larger expanses of land to become cultivated, so farming took over many natural areas that were important for wildlife
C. Machines took away jobs commonly performed by farm workers
D. Machines diminished the quality of the crops.
The correct answer is B. Modern technology allowed for larger expanses of land to become cultivated, so farming took over many natural areas that were important for wildlife.
Explanation:
In the last decades, the creation of agricultural technology has increased the efficiency of growing crops. This means now, all the process is more efficient, which leads to more products to be sold and an increase in profit. However, the possibility of large scale agriculture has caused more land is used for this purpose. This often implies natural ecosystems such as forests are destroyed and the land of these ecosystems, which is usually rich in minerals, is used for extensive agriculture. This is a negative consequence of agricultural technology as natural areas important for wildlife are taken for human profit.

a) List three examples of ruminant livestock. b) Describe how ruminant cattle digest food? c) Why do cattle produce more methane than other types of animals?
Answer:
a)Ruminants include cattle, sheep, goats, buffalo, deer, elk, giraffes and camels. These animals all have a digestive system that is uniquely different from our own. Instead of one compartment to the stomach they have four. Of the four compartments the rumen is the largest section and the main digestive centre.
b)Digestion in ruminants occurs sequentially in a four-chambered stomach. ... The mass is finally passed to the true stomach, the Abomassum, where the digestive enzyme lysozyme breaks down the bacteria so as to release nutrients.
c)The difficult-to-digest grass ferments in the cows' stomachs, where it interacts with microbes and produces gas. Thus,cattle produce more methane than other types of animals.

A scientist thinks that a certain chemical is a mutagen. She exposes plant cells to a large amount of this chemical in
the laboratory
Which statement best provides evidence that the substance is a mutagen?
The cells die within hours of being exposed to the chemical.
The cells grow more quickly than those that were not exposed to the chemical.
The cells change after being exposed to the chemical, and this change is passed to the next generation of cells.
The cells continue to divide at the same rate as before they were exposed to the chemical.
Answer:C
Explanation:it’s 100% C
If a scientist thinks that a certain chemicals is a mutagen and expose plant cells to a large amount of such chemical in the lab, the statement that best provides evidence that the substance is a mutagen would be that the cells change after being exposed to the chemical, and this change is passed to the next generation of cells.
A mutagen is generally described as a chemical that is capable of causing mutation in cells. Mutation in itself refers to heritable changes to the genome of a cell or an organism.
Hence, if a chemical is suspected to be a mutagen, such chemical must be able to cause mutation in the cells if they are exposed to it in large amount. The chemical should force some changes to the cell and the changes should be inheritable by the next generation of cells.

. As biochemists we are aware that the sequence of proteins influences their 3D structure and that these structures ultimately define the final function of each protein. Give these facts explain how the sequence and structure of K+ channels influence what ions are to be transported.
Answer:
See below
Explanation:
Potassium channels have the ability to allow only potassium ions to pass through with a remarkable accuracy. This is achieved due to the presence of a selectivity filter. There are 8 molecules of water that surround this filter. If the K+ ion is to go through the filter, it will have to lose these molecules. The dimensions of this pore, as determined by its 3D structure, correspond only to the K+ ions and not Na+ ions which are smaller in size and thus, will not be able to pass through the filter.
A karyotype shows that a child has Klinefelter syndrome (47,XXY). If the child is also color-blind (due to a recessive X-linked allele), despite his parents having normal color vision, in which parent and stage of meiosis did nondisjunction occur?
Answer:
It occurred in the mother and in meiosis II stage
Explanation:
A karyotype shows that a child has Klinefelter syndrome (47,XXY) which involves a male child having an XXY chromosome in which the XX chromosome codes from the mother.
If the child is also color-blind (due to a recessive X-linked allele), despite his parents having normal color vision then the nondisjunction occurred in meiosis II because sister chromatids separate during meiosis II and the non separation is the reason for the Klinefelter syndrome.
Which of these lymphoid organs destroys bacteria before it can breach the intestinal wall and generates "memory" lymphocytes for long-term memory?
Answer:
Peyers patches
Explanation:
Peyers patches are group of lymphoid follicles found in the ileum of the small intestine.
This part of lymphatic system form part of immune system that help to control bacteria population in the small intestine and prevent the growth of pathogenic bacteria in the small intestines. It plays an important role in immune surveillance where it recognises pathogenic bacteria and destroy the bacteria.
It is a lymphoid organs destroys bacteria before it can breach the intestinal wall and generates "memory" lymphocytes for long-term memory because it form the part of the immune system which help to fight infection or foreign substances in the body, also by generating lymphocytes which is a white blood cells of the immune system which generate long term memory of foreign pathogens and destroying it.
