Under which of the following circumstances might the nutrient levels in manure be tested?
if it will be sold as fertilizer
if it is thought to contain pathogens
if a farmer or rancher wants to change the nutrients in his or her soil
if a CAFO’s Animal Waste Management Plan (AWMP) is being reevaluated
Answer: if a farmer or rancher wants to change the nutrients in his or her soil
Explanation:
The nutrients in the manure plays an important role in growth and development of the crops and they improve the fertility of the soil. Certain mineral elements present in the manure can change the pH of the soil which can affect the growth of the plants. Thus the mineral content of the manure should be tested thoroughly before changing the nutrients in the soil by providing the manure to the soil.
Answer:
If the farmer wants to change the nutrients in his or her soil.
Explanation:
Took the test.
You cross an individual with genotype XXYYZZ to an individual with genotype xxyyzz, and F1 progeny are collected. Assume interference between regions (X-Y and Y-Z) is 100%. When an F1 individual produces gametes, what proportion of its gametes would have xyz genotype
In the first cross one of the parent has only dominant allele and one has only recessive allele that means the offspring in F1 will be 100% heterozygous

Answer:
Revolving nosepiece
Explanation:
The revolving nosepiece (also called the turret) is the part of the microscope we can turn in order to view an object through different objective lenses. Objective lenses, which provide different levels of magnification (usually 4x, 10x, 40x, and 100x), are all attached to the revolving nosepiece. It allows us to switch lenses from those that provide less magnification to those that provide more. This is how we can see more details on an object we're observing.
You can see what this part of the microscope looks like in the image attached below:

Secondary succession is faster than primary succession C. Primary and secondary succession usually proceed at the same rate because they both followed a large disturbance. D. Succession rates would depend on the number of early arriving facilitator species.
Answer:
The answer is option D "Succession rates would depend on the number of early arriving facilitator species"
Explanation:
Ecologists have a solid interest in knowing how communities structure and change over the long run. Indeed, they have invested a ton of energy seeing how complex communities, such as forests, emerge from void land or uncovered stone. They study, for instance, locales where volcanic eruptions, ice sheet retreats, or out of control fires have occurred, clearing land or uncovering rock.
In examining these destinations over the long haul, ecologists have seen steady cycles of progress in natural communities. As a rule, a community emerging in an upset territory experiences a succession of movements in synthesis, frequently throughout numerous years. This arrangement of changes is called natural succession.
Succession is a progression of reformist changes in the structure of an ecological community over the long run.
In primary succession, recently uncovered or recently shaped stone is colonized by living things unexpectedly.
In secondary succession, a territory recently involved by living things is upset then recolonized following the aggravation.
Long legs (L) in racing horses is dominant to short legs (l). Good muscle tone (G) is dominant to weak muscle tone (g). Determine the phenotypes of the F1 generation resulting from a cross between a heterozygous long legged, weak muscled horse and a heterozygous long legged, strong horse
Answer:
See the answer below
Explanation:
Long leg (L) is dominant over short leg (l) and Good muscles (G) is dominant over weak muscles (g).
Heterozygous long leg, weak muscle = Llgg
Heterozygous long leg, strong muscle = LlGg
Llgg x LlGg
Offspring:
2 LLGg - Long leg, strong muscle
4 LlGg - Long leg, strong muscle
2 LLgg - Long leg, weak muscle
4 Llgg - long leg, weak muscle
2 llGg - short leg, strong muscle
2 llgg - short leg, weak muscle
Ratio of offspring with long leg and strong muscle = 6/16 or 3/8
Ratio of offspring with long leg and weak muscle = 6/16 or 3/8
Ratio of offspring with short leg and strong muscle = 2/16 or 1/8
Ratio of offspring with short leg and weak muscle = 2/16 or 1/8

Which of the following represents a scenario of potassium cyanide toxicity?
-The substrate-level phosphorylation of glucose generates all the ATP required by the cell.
-Chemiosmosis still occurs in the inner mitochondrial membrane and generates all the ATP during cellular respiration.
-Oxidative phosphorylation that generates most of the ATP is blocked, and oxygen cannot accept the electrons from NADH.
-Electrons cannot be transferred from NAD to NADH, and ATP generation from both the substrate level and oxidative phosphorylation is blocked.
Answer:
Oxidative phosphorylation that generates most of the ATP is blocked, and oxygen cannot accept the electrons from NADH.
Explanation: Sorry this is late and may be wrong but it is my best guess and here is why:
Potassium cyanide blocks the ETC where the majority of ATP is produced. The ETC is a oxidative phosphorylation process where oxygen is needed as the final electron acceptor of NADH.
The first answer can be eleminated because oxidative phosphorylation produces the most ATP.
The second answer can be eleminated because chemiosmosis does not generate ALL the ATP during cellular respiration, but does produce most of it. Still they worded it as an "all or nothing" type of question so I don't think it is correct.
The fourth answer may not be correct because NAD does not pass on an electron to NADH. Instead, NADH donstes electrons to the ETC and is then turned into NAD. So the process listed is technically backwords.
Sorry I can't be sure about the answer but this is how I broke it down.

A. The null hypothesis should be rejected because the critical value is less than the calculated value B. The null hypothesis should not be rejected because the critical value is less than the calculated value C. The null hypothesis should not be rejected because the critical value is greater than the calculated value D. The null hypothesis should be rejected because the critical value is greater than the calculated value
Answer:
the correct answer is A
Explanation:
Chi squared is a statistical test that is used either to test whether there is a significant difference, goodness of fit or an association between observed and expected values. the sqaure for this is less than the statistical value originally found, therefor making the null hypothesis void.
The Chi-square test is defined as the statistically significant difference between the expected frequency and observed frequencies.
The correct option is:
Option A. The null hypothesis should be rejected because the critical value is less than the calculated value
The Chi-square test is based on hypothetical facts to determine the significant difference in the calculated and observed frequencies.
The null hypothesis is rejected because the square for the value is less than the statistical or calculated value originally found. Thus, the hypothesis is null and void.
Therefore, the correct option is A.

what is the role/function of neurohormones in annelied?
Answer:
Phylum Annelida
There is a complex just beneath the brain that functions as a neurohemal organ. The epithelial cells found in this complex may be secretory as well, but this has not been proved. Neurohormones are released from the infracerebral complex into the coelomic fluid through which they travel to their targets.
it it is located at the base of the brain near the pituitary gland it's very small the hypothalamus plays a crucial role in many important functions include releasing hormones regulating body temperature.

A scientist fused a mouse cell and a human cell, then treated the cell with specific antibodies covalently linked to colored fluorescent dyes (antibodies to mouse proteins were labeled green; antibodies to human proteins were labeled red). Forty minutes later, what will the researcher observe
Answer:
The researcher observes a hybrid cell.
Explanation:
When a researcher perform an experiment in which he fused mouse cell with a human cell, a hybrid cell is formed. This fusion is done in the presence of Sendai virus which helps to combine two different types of cells with each other and produced a hybrid cell. These somatic hybrid cells contain the entire part of the mouse genome and a few number or parts of human chromosomes.
2. Protein A has a binding site for ligand X with a Kd of 10-6M. Protein B has a binding site for ligand X with a Kd of 10-9M. Which protein has a higher affinity for ligand X
Answer:
Protein B has a higher affinity for ligand C than protein A
Explanation:
Binding affinity is a measure of the strength of the bonds or interactions between a single biomolecule or receptor to its ligand. A ligand is usually a small molecule that binds to a specific receptor.
The receptor is usually a large molecule that contains a specific site for the binding of ligand.
Binding affinity is usually measured by the equilibrium dissociation constant (KD). The equilibrium dissociation constant KD is a ratio of the dissociation and the association of ligand to the receptor. The value of KD is used to evaluate and compare the strengths of bimolecular interactions. The larger the KD value, the more weakly the target molecule and ligand are attracted to and bind to one another.
The higher the dissociation constant (KD), the weaker the affinity is between the interacting molecules, whereas, the smaller the KD value, the greater the binding affinity of the ligand for its target.
Protein B has a KD value of 10⁻⁹ M while Protein A has a KD of 10⁻⁶ M.
Ration of KD of protein B to protein A = 10⁻⁹ M/10⁻⁶ M = 10⁻³
Therefore, protein B has a KD value which is 1000 times smaller than the KD of protein A.
Any four effect of snowslide
Explanation:
An avalanche (also called a snowslide) is an event that occurs when a cohesive slab of snow lying upon a weaker layer of snow fractures and slides down a steep slope. Avalanches are typically triggered in a starting zone from a mechanical failure in the snowpack (slab avalanche) when the forces of the snow exceed its strength but sometimes only with gradual widening (loose snow avalanche). After initiation, avalanches usually accelerate rapidly and grow in mass and volume as they entrain more snow. If the avalanche moves fast enough, some of the snow may mix with the air forming a powder snow avalanche, which is a type of gravity current.

Because it interferes with the assembly of microtubules, its effectiveness must be related to Group of answer choices disruption of mitotic spindle formation. inhibition of regulatory protein phosphorylation. suppression of cyclin production. inhibition of DNA synthesis.
Answer:
The correct answer is ''disruption of mitotic spindle formation.''
Explanation:
Vinblastine blocks mitosis by inhibiting the formation of microtubules in the mitotic spindle, which results in the interruption of cell division in the metaphase stage, thus having a specific action of the M phase of the cell division cycle . Its activity may also be related to an interference of the amino acid metabolic pathways that lead from glutamic acid to the citric acid cycle and to urea.
