Genes A and B are 10 map units apart and genes B and C are 20 map units apart, with gene B located between genes A and C. What would be the expected amount of double crossovers for a trihybrid test cross
Answer:
2% of the progeny will be double crossovers for the trihybrid test cross
Explanation:
By knowing the positions of genes, we can estimate the distances in MU between them per region.
Genes A and B are 10 map units apart (Region I)Genes B and C are 20 map units apart (Region II)Genes A and C are 30 map units apart----A-------10MU--------B-------------20MU-------------C---
Region I Region II
We can estimate the recombination frequencies by dividing each distance by 100.
• recombination frequency of A-B region = 10MU / 100 = 0.10
• recombination frequency of B-C region = 20MU / 100 = 0.20
Now that we know the recombination frequencies in each region, we can calculate the expected double recombinant frequency, EDRF, like this:
EDRF = recombination frequency in region I x recombination frequency in region II.
EDRF = 0.10 x 0.20 = 0.02
2% of the progeny will be double crossovers for the trihybrid test cross

Describe the scientific theory of cells (cell theory) and relate the history of its discovery to the process of science.
Answer:
The cell theory states that all living organisms are made up of cells and each cell is the fundamental and functional unit of the living organism. The last point of the theory is that each cell is produced by a pre-existing cell.
The cell discovery was made by Robert Hooke with the help of the compact microscope was made by him. He observed the cell wall of the cell in cork and after him, many other scientists proved the presence of cells and presented evidence of the cell theory.
A scientist believes that she has found a new life form. Which of the following conditions is NOT considered essential in determining whether the putative new life form exhibits/shows the properties of life?
a. It appears to have cells when viewed under a microscope
b. It seems to react to being touched
c. It possesses a purposeful anatomical structure that differs from one another
d. It's body is bilaterally symmetrical
Answer: It's body is bilaterally symmetrical
Explanation:
The option that is not considered essential in determining whether the putative new life form shows the properties of life is that its body is bilaterally symmetrical.
The fact that the creature has cells signifies that it has life, reaction towards touch is also another factor that shows its has life.
We should note that its body shape doesn't signify I it has life or not. Therefore, the answer is D.

Which phylogenetic tree shows that lactation--the production of milk to feed young--is a homologous trait in humans, dogs, and bats (but not in birds and lizards)
Answer:
The correct answer is - choice 1 in the image.
Explanation:
In this given question there are four phylogenetic trees are given among these four trees one tree shows the milk production to feed young ones which is mologous case in humans, bats, and dogs as they show lactation whereas lizards and birds do not show lactation.
In these four the first option shows the homologous condition at the second branch where milk production is divided from lizard and birds.

Explanation:
The inflammatory response does not: Question 15 options: Replaces damaged tissue with healthy tissue Prevents the spread of disease to surrounding tissues Starts the repair process of the tissue Disposes of the cellular debris The inflammatory response does all of the above.
Answer:
The correct option is Replaces damaged tissue with healthy tissue
Explanation:
This is because inflammatory response refer to series of occurrences that happens when tge body tissues suffer injury from chemicals, toxins, heat,trauma or other things. Tge damaged cells releases chemicals like histamine and make the blood vessels to accumulate fluid and then swell. The chemicals then separate the foreign substances from the normal one. These chemicals attracts white blood cells called phagocytes which swallow up the dead damaged cells

A landform being broken apart is weathering erosion or deposition? and is a glacier forming from an accumulation of ice and snow is weathering and erosion or deposition? please help fast
Answer:
A landform being broken apart is WEATHERING.
A glacier forming from an accumulation of ice and snow is DEPOSITION
Explanation:
This is because weathering is the process where rocks or landforms are broken down into smaller pieces sometimes form soul through the activity of an agent which could be wind, water, ice, gravity e.t.c.
While Deposition is the accumulation of segments of particles in a new location forming another shape after it has been wash away(erosion) into that new location by water, ice, wind, gravity e.t.c.
Answer:
A landform being broken apart is weathering.
A glacier forming from an accumulation of ice and snow is deposition

Explanation:
why does the addition of phosphate compounds to aquatic areas have a dramatic effect on biological productivity
Answer:
Explanation:
The presence of the phosphates compound here act as limiting factors for plant growth in aquatic ecosystems, because they do not dissolve easily in water . Then eutrophication( this is the gradual rise in the concentration of phosphorus, nitrogen, and other plant nutrients in an aging aquatic ecosystem.) starts acting wherever there is too much phosphate, it promotes excessive amount of algae and it will exhaust the oxygen.
You are solving a density problem, where density = mass/volume. Your volume of liquid is 2.1 milliliters. Your mass of the liquid is 2.811 grams. What is the density of the liquid using the correct number of sig figs?
Answer:
Density = 1.3386kg/m³
Explanation:
Given the following data;
Volume = 2.1 millimeters to meters = 2.1/1000 = 0.0021 meters
Mass = 2.811 grams to kilograms = 2.811/1000 = 0.002811 kilograms
To find the density;
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the equation;
[tex]Density = \frac{mass}{volume}[/tex]
Substituting into the equation, we have;
[tex] Density = \frac {0.002811}{0.0021} [/tex]
Density = 1.3386kg/m³
