Punnett squares use mathematical probability to help predict the genotype and phenotype combinations in genetic crosses. Select the steps below that describe how to construct Punnett squares.
Question:
I failed to find the options, but I will post the way by which you can construct Punnett squares.
Answer and Explanation:
First, you need to know both parental individuals´ genotypes. From these genotypes, you will get all the possible gametes for each parent, following the principle of simple segregation.
Then, by using a simple square, you will make the crosses. This is:
You will locate all the possible gametes of one parent on the top of the squareYou will place all the possible gametes of the other parent on the left edge of the square.Once you have done that, you will perform the crosses. You will look for the intersection between each parent´s gametes and place all the involved alleles in the intersection-box. These are the possible genotypes, and they will be written within the square.In the attached files, you will find an example of the cross between two pure-breeding plants.
How is erosion by glaciers an example of water shaping the landscape?
Answer:
A glacier's weight, combined with its gradual movement, can drastically reshape the landscape over hundreds or even thousands of years. The ice erodes the land surface and carries the broken rocks and soil debris far from their original places, resulting in some interesting glacial landforms.

Explanation:
practice. Consider the negative human impact described in the left column of the chart below. Then explain a possible solution for it in the column on the right.
Negative Human Impact Possible Solution Large sections of rainforest are burned to remove trees and create farmland.
Building a new subdivision forces native animal species out of habitats.
Massive oil spill destroys marine habitat and significantly lowers marine populations.
A hydroelectric power plant requires a dam that floods a nearby forest.
Give a possible solution
Answer:
Use high yielding varieties, strong structure of oil tankers and build dams far away from forest.
Explanation:
In order to create a farmland, don't burned rainforest because the solution is that we have to use high yielding varieties in order to gain more production from the same piece of land instead of increasing the area for more production. Check for the leakage or use an oil tanker which has good structure in order to avoid spilling of oil in the water. Built hydroelectric power plant at that place where there is no forest is present nearby so we can flood that area.

This is a diagram of the major organs of the human female reproductive system. We would find these organs in what body cavity?
es
A)
abdominal
B)
abdominopelvic
a
dorsal
D)
thoracic
Answer:
B) Abdominopelvic
Explanation:
In the female body, it is actually on the pelvic area where the internal reproductive organs are, but since the options given here mention the closest being the abdominopelvic it's what feels more accurate.
You can also solve this by the process of elimination if you know what organs are where from the options: The abdominal cavity mostly means where upper and part of the lower GI system is, kidneys, liver, etc. The dorsal cavity is what's BEHIND the body (aka the cranial cavity + the spinal cavity so your brain and spine) and the thoracic cavity mostly involves lungs, trachea, part of the esophagus and the pericardial cavity (your heart). So by that logic, the abdominopelvic joins both what's in the abdominal AND pelvic cavity (which are the reproductive organs and bladder).
I attached a diagram in case it helps you to visually understand what I explained.

What causes a sea and land breeze?
☁️ Answers ☁️
☁️ During the day, the sun heats up both the ocean surface and the land. The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean. At night, the roles reverse. ☁️
❤️
☁️ Land: The land breeze is a coastal breeze at night blowing from the land to the ocean. It is caused by the difference in the rates of cooling of the land and of the ocean. Once again, the bigger the difference in temperature between the two, the stronger the wind ☁️
☁️ Sea: A sea breeze is created when a low pressure forms over the coast. The sea has a greater heat capacity than land, meaning it requires more heat to change its temperature. Therefore, during the day, as the sun’s warm rays shine down on the earth, because of the difference in heat capacity, the land heats up faster than the sea. ☁️
Hope it helps.

Describe the relationship between the respiratory and circulatory systems and ATP. Use the term reactants in your response.
Answer:
Cellular respiration, which generates ATP in your cells, requires oxygen to take place, also, it generates CO2 as a waste product. The respiratory system allows oxygen to diffuse into your blood, and carbon dioxide to diffuse out. The blood then carries the oxygen to the cells, so cellular respiration to continue. When the blood reaches the cells, it also takes the carbon dioxide out of the cells, and carries it to the lungs to get rid of it.

While it may seem obvious today, most people at the time did not believe that fossils were once part of living creatures. The reason was that the fossils of clams, snails, and other marine animals were found in tall mountains, miles from any ocean. Two schools of thought explained these fossils. Some religious writers believed that the shells were washed up during the Biblical flood. But this explanation could not account for the fact that fossils were not only found on mountains, but also within mountains, in rocks that had been quarried from deep below Earth’s surface. Seeking an alternate explanation, other writers proposed that the fossils had formed within the rocks as a result of mysterious forces. In other words, fossil shells, bones, and teeth were never a part of a living creature!
Steno had other ideas. For Steno, the close resemblance between fossils and modern organisms was impossible to ignore. Instead of invoking supernatural forces to explain fossils, Steno concluded that fossils were once parts of living creatures. He then sought to explain how fossil seashells could be found in rocks far from any ocean. As in the Tyrannosaurus rex Figure 11.10, fossils resemble living organisms.
Superposition of Rock Layers
Steno first proposed that if a rock contained the fossils of marine animals, the rock was formed from sediments that were deposited on the seafloor. These rocks were then uplifted to become mountains. Based on those assumptions, Steno made a remarkable series of conjectures that are now known as Steno’s Laws.

What are the different types of blood? Explain
Answer:
There are 4 different blood types: A, B, AB, and O. Genes that you inherit from your parents (1 from your mother and 1 from your father) determine your blood type. Blood is always being made by the cells inside your bones, so your body can usually replace any blood lost through small cuts or wounds.

The atom shown below is
A. likely to form a covalent bond
o B. likely to form an ionic bond
C. not likely to form any bonds
OD. likely to form double bonds
Answer:
C. Not Likely to form any bonds
Explanation:
Assuming this atom is of neutral charge, it would be neon. We can tell as it has 10 electrons total. 2 in the first shell, 8 in the second. Noble gasses do not form bonds, generally speaking.
Furthermore, any atom, ion or not, that has a full valance (outermost shell) is generally not likely to form bonds.
How does human activity impact Earth's systems such as deforestation
urbanisation desertification, erosion, air and water quality, and
allemating the flow of water?**Please use full sentences ****
Answer: Land, Water,Urbanization, and smog and acid rain.
Explanation:
Smog and acid rain are produced through similar sources, primarily vehicle and industry emissions. Though both result from human-caused air pollutants, there are chemical distinctions between the two. Though there are regulations in effect to reduce both types of pollution, they remain a threat to both human health and the environment.Smog Causes A combination of three components -- nitrogen oxides, volatile organic compounds (VOCs) and sunlight -- causes smog. Nitrogen dioxide interacts with sunlight to create nitrogen oxide and a free oxygen molecule. This interaction produces ozone, which typically turns back into nitrogen dioxide, and the cycle repeats. The addition of VOCs interrupts the cycle, however. VOCs are produced by various sources, such as paint, cleaning products and refrigerants. The VOCs prevent the breakdown of ozone, allowing it to gather near the surface of the Earth, where even more nitric oxides are produced by vehicle and industry emissions, creating the dense smog seen in large cities such as Los Angeles and Beijing.Smog Hazards The presence of ozone in the form of smog can have several negative health effects. Respiratory systems can be irritated, reducing overall lung function and triggering asthma attacks. Evidence reported by the Environmental Protection Agency also suggests exposure to ozone reduces immune system responses, especially in the lungs. These effects subside over time, but little is known about the long-term effects of repeated exposure. Vegetation also suffers from smog, as plants that take up too much ozone can be damaged in ways such as discoloration and a loss of leaves that cuts photosynthesis efficiency by up to 50 percent.
