What is the typical F2 ratio in the case of dominant epistasis?
Answer:
12:3:1
Explanation:
The typical F2 ratio in cases of dominant epistasis is 12:3:1.
The epistasis is a form of gene interaction in which an allele in one locus interacts with and modifies the effects of alleles in another locus. There are different types of epistasis depending on the type of alleles that are interacting. These include:
Dominant/simple epistasis: Here, a dominant allele on one locus suppresses the expression of both alleles on another locus irrespective of whether they are dominant or recessive. Instead of the Mendelian dihybrid F2 ratio of 9:3:3:1, what is obtained is 12:3:1. Examples of this type of gene interaction are found in seed coat color in barley, skin color in mice, etc.Other types of epistasis include recessive epistasis (9:3:4), dominant inhibitory epistasis (13:3), duplicate recessive epistasis (9:7), duplicate dominant epistasis (15:1), and polymeric gene interaction (9:6:1).What are two main categories of ecosystems

Decide which of the following forms of human communication are analogous to autocrine, paracrine, endocrine, and synaptic signaling by cells. A. A telephone conversation B. Talking to people at a cocktail party C. A radio announcement D. Talking to yourself - autocrine
Answer: Option A.
Telephone conservation.
Explanation:
It is telephone conservation because it is analogous to synaptic signalling because it involve a personal conversation between a person who is far away or very distant and both the communicator and the recipient are able to receive message between each other or they are able to communicate their thought which is synonymous to synaptic signalling.
Cells connect to each other to communicate to each other over long distance through these three main ways and they are gap junctions, tight junctions, and desmosomes.

You want to prepare a 1:50 dilution of your protein extract in a total volume of 1000 uL. You will need ___ uL of protein extract and ___ uL of water.
I’ll mark the brainliest!!
Answer:
20uL of protein, 980uL of water
Explanation:
According to the question, a protein extract is about to be prepared using a 1:50 dilution of the extract in a total volume of 1000uL.
1:50 means there will be;
1/50 part of protein and 49/50 part of water.
Hence, in a total volume of 1000uL, one would need:
Protein extract: 1/50 × 1000 = 20
Water: 49/50 × 1000 = 980
Therefore, 20uL of protein and 980uL of water will be needed to make a 1000uL solution containing protein extract and water in the ratio 1:50
One of the buffers that contribute to pH stability in human blood is carbonic acid (H2CO3). Carbonic acid is a weak acid that, when placed in an aqueous solution, dissociates into a bicarbonate ion (HCO3-) and a hydrogen ion (H+), as noted below.
Answer:
Yes, carbonic acid is the part of blood buffer system.
Explanation:
Carbonic acid is a part of blood buffer system which helps in regulating of pH of the blood. Hydronium ion is responsible for the increase in acidity of the blood. The carbonic acid dissociates into bicarbonate and hydrogen ion, this bicarbonate ions react with the hydronium ion and prevent the pH of the blood from decreasing so we can say that carbonic acid is an essential part of blood buffer system.

Which visualization best helps the reader see the relationship between the two variables temperature and radiation why
Answer:
The correct answer is - scatter plot.
Explanation:
A Scatter plot is one of the visualization tools which is used to show or represent how much a single variable is affected by the other or what are the effects they have on one another. This visualization tool uses the position of dots on a graph to represent the values of variables.
Scatter plot helps in the show the relation or correlation of variables like temperature and radiation as they affect one other, if the dots are closer it means they have more correlation and vice versa.
Thus, the correct answer is - scatter plot.

A transgenic mouse animal model is created that expresses both the Cre recombinase gene, under control of a promoter for a gene expressed only in muscle fibers, and an androgen receptor with loxP sites around exon 2. How will expression of the androgen receptor protein be altered in the transgenic mouse
Answer:
The Cre-lox system triggers recombination of the androgen receptor gene in muscle cells
Explanation:
The Cre-lox system is capable of producing site-specific recombination events in a given DNA region. This technique enables the spatial and temporal control of target gene expression. The Cre-lox system contains a recombinase enzyme (Cre recombinase) that allows the recombination of specific nucleotide sequences (LoxP sequences), being thus used to produce genetic modifications (i.e., insertions, deletions, translocations, inversions, etc.) at target loci where LoxP sequences were inserted.

Two capacitors of 1μF and 2μF are connected in series across a 100V supply. The energy stored in the system is ?
Answer:
In series : 1/C=1/C1+1/C2
1/C=1/1+1/2
1/C=3/2
C=2/3=0.66
Explanation:
Energy=1/2CV^2
Energy=1/2*0.66(100)^2
Energy=1/2*0.66(10000)
Energy=1/2*6600
Energy=3300J
The energy stored in the system of capacitors is 3350 μF-Volt the energy stored in the system of capacitors is 3350 μF-Volt.
To find the total energy stored in the system of capacitors connected in series, we need to follow these steps:
Step 1: Calculate the equivalent capacitance (C_eq) for capacitors connected in series.
When capacitors are connected in series, the reciprocal of the equivalent capacitance (1/C_eq) is equal to the sum of the reciprocals of the individual capacitances (1/C1 + 1/C2).
For two capacitors, C1 = 1μF and C2 = 2μF, the equivalent capacitance (C_eq) is given by:
1/C_eq = 1/C1 + 1/C2
1/C_eq = 1/1μF + 1/2μF
1/C_eq = 2/2μF + 1/2μF
1/C_eq = 3/2μF
Now, find the equivalent capacitance (C_eq):
C_eq = 2/3 μF = 0.67 μF
Step 2: Calculate the total energy (E) stored in the system.
The energy (E) stored in a capacitor is given by the formula:
E = (1/2) * C * [tex]V^2[/tex]
Where:
E = Energy stored
C = Capacitance
V = Voltage across the capacitor
Using the equivalent capacitance (C_eq ≈ 0.67 μF) and the supply voltage (V = 100V):
E = (1/2) * C_eq * [tex]V^2[/tex]
E = (1/2) * 0.67μF * [tex](100V)^2[/tex]
E = (1/2) * 0.67 * 10000μF-Volt
E = 3350μF-Volt
So, the energy stored in the system of capacitors is 3350 μF-Volt.

Living things should not be viewed under a(n) _____ because the preparation process would kill them.
Answer:
Electron Microscope
Explanation:
In contrast to light microscopes, electron microscopes use a beam of electrons instead of a beam of light. Not only does this allow for higher magnification and, thus, more detail, it also provides higher resolving power. The method used to prepare the specimen for viewing with an electron microscope kills the specimen. Electrons have short wavelengths (shorter than photons) that move best in a vacuum, so living cells cannot be viewed with an electron microscope.
