Use the information to answer the following question.
A population of rabbits lives in a grassy field that is lush and green in summer and covered in snow in winter. At the start of the summer,
75% of the population are white rabbits, and the remaining 25% of the population are brown rabbits. In rabbits, white (W) is dominant
over brown (w). During the summerthe field where they live experiences a drought. The
summer drought lasts for two years, through
many generations of rabbits.
Which prediction BEST estimates the expected percent of white and brown rabbits in the population at the end of the
drought?
O A. The rabbit population will consist of 0% white rabbits and 100% brown rabbits.
OB. The rabbit population will consist of 35% white rabbits and 65% brown rabbits.
C. The rabbit population will consist of 95% white rabbits and 5% brown rabbits.
D. The rabbit population will consist of 80% white rabbits and 20% brown rabbits.
Answers
Answer:B
Explanation:
The rabbit population will consist of 35% white rabbits and 65% brown rabbits. Therefore, option B is correct.
What are the limiting factors of the rabbit population?Until a limiting factor, such as low reproduction, food scarcity, predation, disease, and/or weather conditions restrict populations, the population tends to grow.
Some density-dependent limiting factors are the spread of pathogens, competition for nesting locations, the destruction of habitat, increase in the population of predators. Several predators, including raptors and coyotes, use rabbits as food, but in urban and suburban areas, cats and dogs pose the biggest threat. Some abiotic limiting factors are drought, flood, earthquake, and all types of natural disasters.
The rabbit population will consist of 35% white rabbits and 65% brown rabbits. Therefore, option B is correct.

What needs to happen FIRST for a fossil to form?
Answers
Answer:
for a fossil to form, an organism must be buried quickly so that any oxygen is cut off and its decay slows down or stops. ... Fossil formation begins when an organism or part of an organism falls into soft sediment, such as mud.
Explanation:
For a fossil to be formed, it is required for a plant or an animal to be covered by the sediment. Thus, the correct option is D.
What is the process of fossil formation?Fossils are the preserved evidence of the organisms which were present on this planet once. There are four types of process which contribute to the formation of a fossil. These are mineralization, carbonization, encrustation and distillation. These processes occur once a living organism has become trapped within the surrounding sediment, and it is primarily depend upon the mineral composition of silt and water available.
Fossil formation begins when a living organism or any part of an organism falls into the soft sediment, such as mud. The organism or part of it then gets quickly buried by more sediment. As more and more sediment collects on top of the organism, the layer with the organism or part becomes compacted and it undergoes deep into the Earth.
Therefore, the correct option is D.

Design your own scenario related to Bacteria or Viruses. Identify the independent and dependent variables.
Answers
Answer:
An experiment where an antibiotic is tested against bacteria. The antibiotic can vary in its concentration for example, different amounts are applied to a sample of bacteria to see if it is affected by the action of the antibiotic and if so, in what concentration. So, the independent variable is the concentration of antibiotic while the dependent variable is the survival (or not) of the bacteria.
Explanation:
An independent variable is a variable that represents a quantity that the scientist modifies in an experiment. A dependent variable represents a quantity whose value depends on how the independent variable is modified. This is the variable being studied and measured.
So, an example of this applied to bacteria or viruses could be:
An experiment where an antibiotic is tested against bacteria. The antibiotic can vary in its concentration, different amounts are applied to a sample of bacteria to see if it is affected by the action of the antibiotic and if so, in what concentration. So, the independent variable is the concentration of antibiotic while the dependent variable is the survival (or not) of the bacteria.
To complete the experiment, an antibiotic whose effect is already known can be used as a positive control. That is, it is already known to kill the bacteria. And as a negative control you can simply use water, which has no effect and is known not to kill the bacteria. In this way, we validate the results and make sure that there is not something else that is affecting the bacteria and that only the antibiotic being studied has an influence.

Explanation:
When you drink too much water, your kidneys can't get rid of the excess water. The sodium content of your blood becomes diluted. This is called hyponatremia and it can be life-threatening.
Hyponatremia is a low sodium concentration in the blood. It is generally defined as a sodium concentration of less than 135 mmol/L (135 mEq/L), with severe hyponatremia being below 120 mEq/L. Symptoms can be absent, mild or severe. Mild symptoms include a decreased ability to think, headaches, nausea, and poor balance.

Answers
A- competition. Rabbits both want grass so it is a competition depending on how much grass there is.
B- competition. Owls and foxes hunting mice is considered two predators hunting, competition for food again.
C. Competition. Even plants don’t get along. Most plants need sunlight to stay alive and weeds grow quickly. The weeds are more or less silently fighting over the yard to keep growing.
D. Not competition. Algae is an underwater plant that most water life tend to feed off of. In this situation the fish would be eating the plant such as how the rabbits ate the grass, there would only be competition if there was less Algae and more fish. But in this case there is Algae and one fish.

Photosynthesis-
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities. Photosynthesis occurs in the chloroplast of a plant, which contains chlorophyll. In order for photosynthesis to take place, it needs to have water and carbon dioxide, the two very important raw materials necessary for this process. In the presence of carbon dioxide, such cells are able to convert this solar energy into energy-rich organic molecules, such as this energy-rich molecule known as glucose. Oxygen the by product of photosynthesis is inhaled by heterotrophs which aids in cellular respiration and other internal processes and then exhales carbon dioxide. ...

Explanation:
The average size of finch beaks also changes because the size of finch beak changes according to the size of seed available. If the environment contains large sized seeds so the population of finch having small beak size increases due to food availability while on the other hand, if the region contains large sized seeds so the population of finch having big beak size increases so according to the size of seeds, the size of finch's beak also changes.
