A woman has blood Type A, her baby has blood Type AB: Is it possible that a man who has the blood Type A could be the father? Show the Punnett Square and explain.
Answers
Answer:
No, it is not possible
Explanation:
Humans use the ABO blood group system where the A and B alleles are dominant over allele O but codominant with one another.
This system is such that;
Type A can only have genotype: iAiA or iAi
Type B can only have genotype: iBiB or iBi
Type AB can only have genotype: iAiB
Type O can only have genotype: ii
According to this question, a woman has blood Type A (iAiA or iAi) and her baby has blood Type AB (iAiB). This means that the father definitely contributed the allele B in order to have a baby with type AB. It also means that, according to the question, IT IS NOT POSSIBLE FOR A "Type A" father to produce that baby (see the punnet square attached).
Note: The father must contain an allele B in his genotype i.e. the father must be either type B (iBiB or iBi) or type AB (iAiB)

Which is a common practice for farmers to yield higher crop production?
A) Overplowing mixes the nutrients in the soil
B) consistently plant the same crop every year
C) allow later-successional growth to replace nutrients
D) keep the area planted with early-successional species
NOT C
Answers
Answer: D) keep the area planted with early-successional species.
Explanation: Early successional species grow fast and spread their seeds rapidly and widely. This could help to bring in a potentially high crop yield.
It likely is not A because overplowing leaves the soil susceptible to erosion and damages the physical infrastructure.
B should not be the answer because consistently planting the same crop year-round can deplete the nutrient resource said crop relies on. It’s why crop-rotating is a thing now.

What are the errors and explain why
Answers
Answer:
1. Oxygen
2. Glucose
3.Light energy
Explanation:
1. Oxygen is not needed by the plant for photosynthesis.
It is a by-product of photosynthesis. Instead Carbondioxide is needed.
2. The glucose produced does not stay solely in the plant, part of it is used up by the plant while others stores in edible parts of the plant that men use as food.
3. The light energy converts H2O to 4H+ and 4OH- needed in the synthesis of carbohydrate and release of Oxygen.

Answer:
Type of Convergence - Ocean to continent for Cascade/ Ocean to Ocean for Aleutian
Explanation:
If the two plates that meet at a convergent plate boundary both are of oceanic crust, the older, denser plate will subduct beneath the less dense plate.
The features of an ocean-ocean subduction zone are the same as those of an ocean-continent subduction zone, except that the volcanic arc will be a set of islands known as an island arc.
The older plate subducts into a trench, resulting in earthquakes. Melting of mantle material creates volcanoes at the subduction zone.
The Cascade Volcanoes are a group of volcanoes in western North America that stretch over 700 miles from southwestern British Columbia through Washington.
Where are Cascade volcanoes?The Pacific Northwest's skyline is dominated by active volcanoes. Volcanoes of the Cascade Range (Public domain.)

A roofer needs to get a stack of shingles onto a roof. Pulling the shingles up manually uses 1,549 n of force. The roofer decides that it would be easier to use a system of pulleys to raise the shingles. Using the pulleys, 446 n are required to lift the shingles. What is the mechanical advantage of the system of pulleys? Explain your answer
Answers
Answer:
[tex]3.47[/tex]
Explanation:
Mechanical advantage is given by the ratio of output force by input force.
[tex]F_o[/tex] = Output force = [tex]1549\ \text{N}[/tex]
[tex]F_i[/tex] = Input force = [tex]446\ \text{N}[/tex]
So,
[tex]MA=\dfrac{F_o}{F_i}\\\Rightarrow MA=\dfrac{1549}{446}\\\Rightarrow MA=3.47[/tex]
The mechanical advantage of the pulley's is [tex]3.47[/tex].

What causes clouds of dust and gas to form a protostar?
Answers
Answer:
Mainly the gravitational instability in the clouds of dust (molecular clouds)
Explanation: Stars are born within molecular clouds, which are mostly made of hydrogen and lesser amounts of helium and other heavier elements. The formation of a protostar begins when gravitational instability is present in the molecular cloud, caused by regions of higher density. Eventually, the clouds of dust start to collapse to due gravity, the protostar forms. The protostar, is still an underdeveloped star, meaning it does not perform nuclear fusion in its core, but it still produces its own heat from the extreme pressure.

Describe the process of photosynthesis by including:
– where it occurs
– its energy source
– any energy transformations that occur
Answers
Answer:
Photosynthesis is the process of transforming sunlight into chemical energy by storing it in the bonds of glucose or sugar.
This process occurs in plants, bacteria and some protists, or algae to produce sugar as food. The chlorophyll present in leaves of photosynthetic plants captures energy from sunlight and converts it to carbohydrates. Photosynthesis uses carbon dioxide (CO2) and water as raw material to produce sugar and release oxygen as a byproduct.
This process uses solar energy to convert carbon dioxide and water into energy in the form of carbohydrates. It is a two-part process. ... Plants, algae and some bacteria use photosynthesis to create energy used for growth, maintenance and reproduction.
