How does the process of sexual reproduction affect genetic material and the passing on of dominant and recessive traits?
Answers
During sexual reproduction, several alleles from both parent cells converge.
What is sexual reproduction?Whoever possesses a more dominant or recessive gene at the time the daughter cell is being formed will have an impact on the genetic material.
Due to the genetic and phenotypic diversity produced by sexual reproduction, people can choose partners based on whom best exhibits these traits.
Due to the options available to sexually reproducing animals, individuals compete with one another and are typically only able to pass on their genes to offspring who exhibit the desirable qualities.
Therefore, during sexual reproduction, genetic material affected due to alleles transfer between parents.

By adding tape to his BAAD, Cramwood increased its mass and increased
its inertia. The bigger BAAD requires more force to stop and ends up smacking Cramwood in the head when he applies the brakes.
What is inertia?Inertia is the tendency of an object to resist a change in its motion. Specifically, it is the property of matter that causes an object to maintain its state of rest or uniform motion in a straight line unless acted upon by an external force.
In other words, an object at rest will remain at rest, and an object in motion will continue to move at a constant speed and in a straight line, unless acted upon by an external force.
The amount of inertia an object has depends on its mass, with more massive objects having more inertia than less massive objects.

Gene banks also preserve cells or organisms that host unusual gene variants — genes with special traits. Those genes might later prove useful when some disease epidemic strikes, when the climate changes or when other factors threaten the survival of plants or animals. Farmers could use the banked deposits — stored cells or tissues — to restore genetic diversity or to introduce traits from other breeds or varieties.
Some gene banks house millions or even billions of plant seeds. One example: the Svalbard Global Seed Vault. It’s located underground on a remote island north of Norway. The San Diego Institute for Conservation Research houses another project, called the Frozen Zoo. Its collection includes cells from thousands of birds, reptiles, mammals, amphibians and fish. The cells stored there might one day be used to help rebuild populations of endangered species.
The Smithsonian and SVF Biodiversity Preservation Project in the United States freezes semen and embryos from rare breeds of domestic animals. The U.S. Department of Agriculture’s Agricultural Research Service (ARS) has an even bigger program. It has almost a million samples of semen, blood and embryos from both common and rare breeds. Such collections serve “as a backup to the United States’ livestock industry,” explains Harvey Blackburn. He’s an animal geneticist. He also manages the National Animal Germplasm Preservation Program at an ARS lab in Fort Collins, Colo.
Gene banks use low temperatures to stop chemical and biological activity that might break down cells. Some banks freeze material in liquid nitrogen at –196° Celsius (-320.8° Fahrenheit). This freezing process replaces water in cells with another fluid, such as glycerol. That fluid minimizes the development of ice crystals. Such crystals could damage cell walls. Later, during thawing, biologists will remove the glycerol or some other fluid and return water to the cells.
Freezing and thawing cells has to be done quickly and carefully so that the material will still be viable after it has warmed back up. But some material requires extra special care.
The sperm from chickens and other poultry, for instance, do not survive the freezing and thawing cycle as well as does the sperm from cows and other mammals. Bird biology partially explains why, says Julie Long. A physiologist, she studies animal reproduction at an ARS lab in Beltsville, Md. Unlike female mammals, hens store sperm for several weeks after a single mating. Then they use those sperm over time to fertilize eggs. So thawed sperm must be very hardy to last such a long while in the female bird’s reproductive tract, she explains.
The shape of the frozen material also can affect how well it survives freezing. Bird sperm looks like a piece of string. That shape makes it more fragile than the sperm of most mammals, which contain a round head and slender tail. Ice crystals can more quickly damage DNA in a bird’s sperm.
But Long and other researchers are working to make the sperm of birds more resilient. “Bird sperm seems to respond better to a very fast freeze,” such as a 200 °C drop in one minute, notes Long. That’s more than three times as fast as the freeze rate necessary to preserve the sperm of mammals.

How does passive transport come into play in oxygen's journey through our body?
Answers
In the alveoli of the lungs, oxygen frequently diffuses from the air into the erythrocytes and blood plasma.
What is passive transport?Diffusion is a form of passive transport where molecules migrate from a high concentration to a low concentration, if you didn't know. Therefore, it follows that the oxygen content of the air must be higher than that of the blood.
Passive membrane transport methods are the most direct. Passive transport is a phenomenon that happens naturally and doesn't require the cell to use energy to move.
Diffusion is the process by which chemicals travel passively from a region of higher concentration to a region of lower concentration.
Therefore, Passive transport is a term that refers to both osmosis and diffusion. They don't need any power.

Create a hypothesis that can be tested in an experiment.
Remember, a hypothesis has a specific "if then" wording.It describes what will happen to the dependent variable when changes are made to the independent variable.For example, "If a plant is fertilized (independent variable), then it will grow faster (dependent variable)."
Design and plan an experiment.
Be sure to identify an independent variable, a dependent variable, and any controls.Remember, controls are factors which stay the same.In an experiment designed to test the previously stated hypothesis, one control would be to use the same kind of plant.Write a complete description of your experiment.Include a list of necessary materials.It is a good idea to follow a step-by-step procedure format.Think of everything you need to do, then write it down in the order it must be completed.Your description and procedure should be clear enough that another person could duplicate your experiment exactly.
Answers
Answer: E
Explanation:
Experiment Design:
Independent Variable: Intensity of light (Low, Medium, High)
Dependent Variable: Rate of photosynthesis (measured by oxygen production or CO2 consumption)
Control: Same kind of plant, constant temperature, constant CO2 concentration, constant water availability, and constant duration of light exposure.
Materials:
Three identical potted plants (of the same species)
Light source(s) with adjustable intensity
Light meter (lux meter) to measure light intensity
CO2 gas sensor or oxygen gas sensor
Timer or stopwatch
Water supply
Thermometer
Data recording sheets
Procedure:
Set up the three identical potted plants in a controlled environment with the same temperature and CO2 concentration.
Ensure that all plants receive the same amount of water.
Place the light source(s) at an equal distance from the plants.
Measure and record the initial light intensity using the lux meter.
Adjust the light intensity to low for the first plant, medium for the second plant, and high for the third plant.
Start the timer and expose the plants to light for a specified duration (e.g., 1 hour).
During the exposure period, measure and record the temperature, CO2 concentration (if possible), and light intensity at regular intervals.
After the exposure period, use the CO2 gas sensor or oxygen gas sensor to measure the change in CO2 concentration or oxygen production, respectively, in the surrounding air.
Record the data obtained from the sensors and calculate the rate of photosynthesis for each plant.
Repeat the experiment multiple times to ensure reliability and average the results.
Analyze the data collected and compare the rates of photosynthesis among the three different light intensities.
Draw conclusions based on the analysis and determine whether the hypothesis is supported or rejected.
By following this experimental design, you can test the hypothesis and determine the effect of light intensity on the rate of photosynthesis in plants. Remember to conduct the experiment in a controlled environment and gather sufficient data for accurate analysis.
What is happening when the angle of the sun hitting the planet during our winter solstice when is that?

Answers
Answer:The summer solstice occurs at the moment the earth's tilt toward from the sun is at a maximum. Therefore, on the day of the summer solstice, the sun appears at its highest elevation with a noontime position that changes very little for several days before and after the summer solstice. The summer solstice occurs when the sun is directly over the Tropic of Cancer, which is located at 23.5° latitude North, and runs through Mexico, the Bahamas, Egypt, Saudi Arabia, India, and southern China. For every place north of the Tropic of Cancer, the sun is at its highest point in the sky and this is the longest day of the year.
The winter solstice marks the shortest day and longest night of the year. In the Northern Hemisphere, it occurs when the sun is directly over the Tropic of Capricorn, which is located at 23.5° south of the equator and runs through Australia, Chile, southern Brazil, and northern South Africa.

Answers
Answer:
Severe weather can occur under a variety of situations, but three characteristics are generally needed: a temperature or moisture boundary, moisture, and (in the event of severe, precipitation-based events) instability in the atmosphere.
Every year in the United States, tornadoes do about 400 million dollars in damage and kill about 70 people on average. Extremely high winds tear homes and businesses apart. Winds can also destroy bridges, flip trains, send cars and trucks flying, tear the bark off trees, and suck all the water from a riverbed.
