What do you think the color of the pea plants has to do with genes?
Answer:
According to Mendel Gregor, he analyzed two plants can make a different offspring. It depends on the alleles. I hope this helped!
Explanation:
Answer:
The instructions for making a pea plant are found in its genes. Each gene has the instructions for one small part of the pea plant. There is a gene that determines the color of the peas the plant will produce. These genes can come in all different versions.
A population ecologist wished to determine the size of a population of white-footed deer mice, Peromyscus leucopus, in a 1-hectare field. Her first trapping yielded 80 mice, all of which were marked with a dab of purple hair dye on the back of the neck. Two weeks later, the trapping was repeated. This time 75 mice were trapped, out of which 48 of the mice were marked. Using the formula below, what is the population of mice in the field
Answer: 125
Explanation:
Population size is the number of individuals in a population. First, the trapping yielded 80 mice that were marked. Two weeks later, 75 mice were trapped and 48 of them had the mark.
The formula used for this question is:
N=mn/x
N= population size in the 1-hectare field. m= number of individuals marked and released the first time. n= number of individuals captured the second time. x= number of marked individuals that are recaptured.
The experiment consist on a randome collect sample of individuals which are then marked and released. Next, take a sample again.
So, replacing the values we get:
N=(80)(75)/48
N=125 individuals.

I need help 1 more time How does the Sun manage to maintain an environment in its core that is conducive to nuclear fusion? I'll mark 1 more Brainliest so plz I really need this done before Monday
Answer:
Gravitational equilibrium helps maintain the environment in the Sun's core that is conducive to nuclear fusion. The Sun's gravitational equilibrium balances the gravity pulling inward and the pressure pushing outward. It keeps the Sun's size, denseness, and hotness stable, thus making nuclear fusion possible.

Which of the following is true about the release of histamine from cells in nasal passages?
All of the above
It may cause increased secretion by mucous membranes.
It occurs during an allergic reaction.
It causes nearby capillaries to swell.
Answer:
Urticaria (Hives)
Hives are an inflammation of the skin triggered when the immune system releases histamine. This causes small blood vessels to leak, which leads to swelling in the skin. Swelling in deep layers of the skin is called angioedema.
Explanation:
How is your body temperature held constant despite different weather temperatures
outside?
Answer:
Core body temperature The body can only stay at a constant temperature if the heat generated is balanced and equal to the heat lost. Although the core temperature must be close to 37°C, fingers and toes can be colder. This is because energy is transferred from the blood as it travels to the fingers and toes.
Answer: When heat activates sweat glands, these glands bring that water, along with the body's salt, to the surface of the skin as sweat. Water evaporating from the skin cools the body, keeping its temperature in a healthy range.
Explanation:
where is the protein on a DNA?
Answer:
Explanation:
The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm. Translation, the second step in getting from a gene to a protein, takes place in the cytoplasm.

2. The temperature of the areas surrounding El Campo before Storm 1 and before Storin 2 was about
15°C. The same amount of wind was blowing toward the air parcels before both storms.
El Campo
Before Storm 1
Before Storm 2
----------
Wind 15°C
15°C
What were the conditions before Storm 2, and why did more rain fall with those conditions?
Answer:
Before storm 1 occurred the air parcels were most likely more warmer hence the Rainfall was higher in storm 1 but before storm 2 the air parcels moved further and lost some energy
Explanation:
Given the temperatures of the areas before storm 1 and storm 2 have the same temperature 15°C and the same amount of wind blew across the areas just before the storms ( storm1 and storm 2 ) occurred.
Hence the conditions before storm 2 that could have caused more rainfall in storm 1 can be attributed to varying atmospheric conditions like; before storm 1 occurred the air parcels were most likely more warmer hence the Rainfall was higher in storm 1 but before storm 2 the air parcels moved further and lost some energy

Mediterranean forests, dry woodlands, and shrublands often have plants called sclerophytes living in them. What adaptation do these plants have that help them survive in this biome?
Answer:
he special characteristics that enable plants and animals to be successful in a particular environment are called adaptations. Camouflage, as in a toad's ability to blend in with its surroundings, is a common example of an adaptation. The spines on cycad leaves, keep animals from eating them.
Explanation:
Plants adapt to their environment from necessity. Plants may also adapt by growing lower and closer to the ground to shield themselves from wind and cold. Desert environments may have some of the following adaptations, these help the plant to conserve food, energy and water and still be able to reproduce effectively.
When you are rating evidence by its value, weigh the benefits of one good fingerprint versus hair and fiber evidence. Fully explain your answer
Answer: Conviction based on the support of the physical fingerprint is a more reliable evidence over hair and fiber evidences.
Explanation:
Physical fingerprint has more value than hair and fiber evidences. As no two fingers can have exactly alike fingerprints belonging to the same person. The fingerprints of two identical twins cannot be alike but DNA evidence obtained from hair, fiber, or any other biological evidences can show similarity. Thus physical fingerprint have more value over DNA fingerprint it can directly related to a suspect to whom it belongs to depending upon the uniqueness of the minutiae characteristics.

How is antibiotic resistance related to Natural selection?
Answer:
Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.
Explanation:
Watch the seven minute video on the "Mystery of the Buffalo boom" on you tube. Write a reflection on how scientists used their reasoning skills to make a claim about causes of the "buffalo boom".
Answer:
In the "Mystery of the Buffalo boom" scientists first try to find the answer in the two most common things that can affect a population of animals. Food and predators.
First, they studied the buffalos' food supply, grass. They found that there has not been an increase in it so that the number of buffalos multiplied.
Then they studied the predator's population, and they found that there was not a decrease in the number of them that could affect the buffalos increasing numbers.
As the two main things that controlled a population were not affected, they had to find other causes. The next thing that they studied were historical facts about buffalos and diseases. Scientists discovered that a virus that affected cows had impacted these animals too, which was the cause of a considerable decrease in the buffalo's population many years back.
Due to the drastic impact that the rinderpest had on cows, a vaccination plan was implemented. As the cows now were protected against this virus, the virus could not reproduce as it did, ending the spreading of this disease in cows. As a consequence, the buffalos were no longer infected, and their population grew thanks to the vaccination plan.
In conclusion, when the most common things that can affect a population are not the cause, we have to look into the past and find what has changed and how it impacted the animals. It is using logical thinking skills to determine what has changed and what that change made.
Explanation:
In the video "Mystery of the Buffalo boom" the ecologist Tony Sinclair found an abnormal buffalos' number in Tanzania. As the increase in the buffalos' population was something unusual, he knew that something had changed, but he did not know what. Sinclair, with other scientists, used their reasoning skills and thought that the two most logical things that can affect a population are food and predators. When they studied these two variables, they found out that they were not the problem. The next step was to look for past events that impacted buffalos. They found out that a virus, which directly affected cows but also buffalos, had been erased from the Earth thanks to a vaccination plan. As a result, the disease spreading between cows stopped, and as a consequence, it also stopped between buffalos.
We can see that everything is connected and that by using reasoning skills and logic, scientists could determine what happened.
How do biotic and abiotic factors affect the characteristics of an ecosystem
Explanation:
Biotic factors such as the presence of autotrophs or self-nourishing organisms such as plants, and the diversity of consumers also affect an entire ecosystem. Abiotic factors affect the ability of organisms to survive and reproduce. Abiotic limiting factors restrict the growth of populations.
