The F2 generations of dihybrid crosses of Labrador retrievers are expected to produce the recessive epistatic ratio of 9 black: 3 chocolate: 4 yellow dogs. A random sample of 80 dogs was taken from F2 crosses. What is the expected number of yellow labs in the sample and what number of degrees of freedom is needed for a chi-square test of recessive epistasis
Answer:
The answer is "2 and 15"
Explanation:
sample of the chocolate labs expected number =chocolate labs fraction [tex]\times[/tex] sample size
[tex]= (\frac{3}{16}) \times 80\\\\ = 15\\\\[/tex]
The dof for recessive epistasis is = n-1, where
n =phenotypes
dof [tex]= 3-1 = 2[/tex]

difference between antigens and antibodies?
Answer:
Antigens are molecules capable of stimulating an immune response. Each antigen has distinct surface features, or epitopes, resulting in specific responses. Antibodies (immunoglobins) are Y-shaped proteins produced by B cells of the immune system in response to exposure to antigens.

Big cats like tigers and other carnivores are often the top predators in an ecosystem. To which trophic level do they most likely belong?
primary producers
decomposers
tertiary consumers
primary consumers
Big cats like tigers and other carnivores are often the to predators in an ecosystem. The trophic level do they most likely belong to is tertiary consumers. Thus, the correct option will be C.
What are Tertiary consumers?Tertiary consumers can be referred to as the carnivore at the topmost level in a food chain which feeds on other carnivores in nature, which is an animal that feeds only on secondary consumers.
Tertiary consumers are those organisms that eats the secondary consumers (large predators) in nature. For example, owl species that eat snakes.
Big cats like tigers and other carnivores are often the to predators in an ecosystem. The trophic level do they most likely belong to is tertiary consumers.

What is meant by "nutrient limitation
Answer:
meaningful additions of an essential element
Explanation:
Nutrient limitation occurs when meaningful additions of an essential element in additions of an essential element in biologically available forms cause an increase in the rate of a biological process (such as primary productivity) and/or in the size of an important ecosystem compartment (such as bi ) biomass).
The three main constituent minerals of granite stones are feldspar, mica, and quartz. The textures of different types of
granite stones are shown in the picture.
Based on the textures, it can be said that
A)
the proportion of mica in all the forms of granite is fixed.
B)
the proportion of quartz in all the forms of granite is fixed.
the three minerals vary in proportion in each form of granite.
D)
the three minerals are in the same proportion in each form of granite.
Answer:
Option C
Explanation:
Granite is composed of coarse-grained quartz and feldspars in varying proportions and due to the varying proportions of these two constituent materials, the texture of granite varies as shown in the image.
Thus, option C is correct
Options A and B and D are incorrect because the constituent material of granite is not fixed. It varies from from place to the other.

What is freezing?The process by which something changes from liquid to solid as the temperature drops is known as freezing. Water basically freezes at 0 degrees Celsius.
The process of changing a substance from a liquid to a solid is known as freezing. When a liquid's molecules slow down enough, their attractions cause them to arrange themselves into fixed positions as a solid.
The average energy of the molecules in a liquid decreases as it cools. At some point, the amount of heat removed is great enough that the molecules' attractive forces draw them close together, and the liquid freezes to a solid.
The particles in a liquid eventually stop moving and settle into a stable arrangement, forming a solid.
Thus, the correct option is B.

Which of the following describes a portion of the water cycle that is not driven by
gravity? O
(1 Point)
B) Precipitation of water that has condensed from clouds
D)Water seeping into the ground to enter an aquifer
C)Water flowing in a river toward the ocean
A) Evaporation of water from the ocean to form clouds
The correct answer is A. Evaporation of ocean water to form clouds.
Explanation
The water cycle is a series of physical-chemical phenomena in which water goes through three states (liquid, solid and gaseous). In this process, the water in a liquid state is evaporated becoming in a gaseous state, and rising towards the sky (against the force of gravity) forming clouds. Once in the clouds, the water condenses, going from a gaseous to a liquid state. After this process, the water precipitates by the action of gravity towards the earth where a process such as the filtration of water in the soil occurs, forming aquifers, the accumulation of water in the rivers that flow into the sea, the freezing of water on the snowy peaks of the mountains, among others. According to the previous explanation, the correct answer is A. Evaporation of ocean water to form clouds.

43. A client says they have a headache, what should the trainer do? A. Recommend they drink water, then stop the training session B. Give them Advil, then stop the training session C. Give them a prescription medication, then continue training session D. Give them Advil, then continue training session
Answer:
A .recommended they drink water then stop training session
Explanation:
Because the trainer can't just give out prescription medication. They don't know if the person has allergies and it can make the clients headache worse.
A. Recommend they drink water, then stop the training session
First thing first, drug abuse is not an option. Drug abuse includes self medication or taking drugs not prescribed by a medical practitioner. As a fitness trainer, ones job is not to prescribe drugs.
According to this question, if a client is experiencing headaches during a training session, the best alternative for the trainer is to recommend taking water to calm the client down, then put an hold to the training. The trainer is not qualified to prescribe any drug whatsoever.
Therefore, the trainer should recommend that a client with headache drink water, then stop the training session.
The owners of a local bakery ask for your help in improving a special yeast strain they use to make bread. They would like you to help them design experiments using RNA interference to turn off genes, to allow them to test their hypothesis that certain genes are important for the good flavors found in their bread. Of the components in the following list, which is the most important to check for in this yeast strain if you would like this project to succeed?
a. the presence of foreign double-stranded RNA
b. the presence of genes in the genome that code for RISC proteins
c. the presence of miRNA genes in the genome
d. the presence of single-stranded siRNAs within the cell
Answer:
b. the presence of genes in the genome that code for RISC proteins
Explanation:
The RNA interference (RNAi) mechanism is a naturally occurring pathway by which eukaryotic cells can silence specific genes both at the transcriptional (eg., by triggering DNA methylation on specific loci) and posttranscriptional (e.g., by triggering mRNA degradation) levels. This mechanism (RNAi) is widely used in molecular biology laboratories in order to silence genes and thus understand their functions. During the RNAi pathway, double-stranded RNAs (dsRNAs) are cleaved into small double-stranded RNA (dsRNA) molecules known as small interfering RNAs (siRNAs) or microRNAs (miRNAs) by an enzyme referred to as "Dicer". Subsequently, these small non-coding RNAs bind to an enzymatic complex known as RNA-induced silencing complex (RISC) that contains a ribonuclease enzyme, i.e., an enzyme that degrades RNA. Finally, the small non-coding RNA (either siRNAs or miRNAs) that are complementary to the RNA target directs the RISC complex to bind and cleave specific mRNAs, thereby silencing gene expression (in this case, by the inhibition of protein translation).

D. 75% Yy and 25% yy
Answer:
B
Explanation:
I assume the plants with the yellow seeds are dominate (YY) , while the ones with green seeds are recessive (yy) (Since it would need to be recessive to be a different color than the dominate). The genes will always be heterozygous then, since it combines the genes from both parents.
