Answer:
b
Explanation:
Two true-breeding stocks of pea plants are crossed. One parent has red, axial flowers and the other has white, terminal flowers; all of the first generation of the offspring have red, axial flowers. The genes for flower color and location assort independently. If 1,000 second generation offspring resulted from the cross, approximately how many of them would you expect to have red, terminal flowers
Answer: 750
Explanation:
Based off the first two sentences, we can conclude that red is the dominant allele and white is the recessive allele.
Let's say R = red and r = white.
The genoytypes of the parents are RR and rr. The genotype of the first generation are all Rr
The punnet square for the second generation is:
R r
R RR Rr
r Rr rr
We can see 3/4 crosses give us red. Now we can multiply 3/4 and 1000 to get 750.

What is a similarity between the temperate climate zone and polar climate zone?
A) Both of the climate zones have warm and hot weather and lots of precipitation.
B) In both polar and temperate zones, the temperature of the warmest month is about 18°C.
C) The temperature can get to 0°C in both temperate and polar climate zones.
D) The temperate and polar climate zones both usually have 150 cm of precipitation.
In both the polar and temperate zones, the temperature of the warmest month is about 18°C. So, the correct option is B.
What are Polar and Temperate zones?Temperate regions are defined as regions with mild temperatures that lie between the subtropical and polar regions where the two regions between the Tropic of Capricorn and the Antarctic Circle or the Tropic of Cancer and the Arctic Circle are called temperate regions.
The polar region is defined as the area around the North Pole or the South Pole, where the North Polar Region consists mainly of flotation and pack ice, 7–10 feet (2–3 m) thick which floats on the Arctic Ocean and is surrounded by land. In both zones, the temperature of the warmest month is about 18°C.
Therefore, the correct option is B.

Which of the following energy producing technologies can be beneficial to soil quality
A. Biomass
B. Solar
C. Wind
D. Oil
Answer:
Both solar energy and wind energy are beneficial to soil quality. They are not using fossil fuels that both harm the soil with digging and fracking, but also are not being burnt which harms the air and can create acid rain. Both solar and wind are using nature to benefit the world. As long as the sun keeps burning and the world turning, we will continue to be able to use them.

In what direction do substances diffuse across the cell
membrane?
Answer:
Since diffusion moves materials from an area of higher concentration to the lower, it is described as moving solutes "down the concentration gradient." The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane.

In the 1950s, Stanley Miller performed experiments to study the origins of life. He created an atmosphere rich in methane, hydrogen, ammonia, water, and simulated lightning. Which substances were most likely produced during Miller’s experiments?
A. protists
B. bacteria
C. amino acids
D. RNA strands
Answer:
c. amino acids
Explanation:
The substances most likely produced during Miller's experiments would be amino acids.
In their simulation of the early atmosphere, Stanley Miller was able to obtain a mixture of organic compounds in the broth with the major one being amino acids.
The discovery of Stanley Miller gave further credence to the chemosynthetic theory of the origin of life because amino acids form the building blocks of proteins and proteins are essential for the onset of life.

The Canadian lynx and the snowshoe hare have a predator-prey relationship. You will use two sets of population data and present them in a single graph.1.Using the second picture below,label the x-axis ‘‘Year of Study’’.Label the x-axis with data listed in the first picture.
2.Based on the sizes of the numbers for each population, create a scale on the two separate y-axes.
From the markings that you had written and erased on your graph, it seems that you already have an idea of what you're supposed to do. Is it that you're having trouble scaling your graph on the provided sheet given the particular data? Or do you have a conceptual question with respect to the instructions?
I've provided the image of the graph according to my understanding of the instructions as stated in 1 and 2, and I've also attached the corresponding Excel spreadsheet that I used to create the graph. While the blank grid that you've attached doesn't scale identically to my graph, it should be possible to transpose the necessary elements into your grid to an acceptable approximation.
That said, please feel free to let me know if you have any clarifications, comments, or questions.

Which change in the gene pool occurred in the greater prairie chicken population?
gene mutation
gene flow
