HELPPP ASAP!! A population of skunks lives in a woodland habitat. The skunks are unable to leave the habitat because of a large mountain. Describe two reasons this population is not at Hardy-Weinberg Equilibrium.
Some of the conditions are there that must be met for a population or an allele to be in Hardy-Weinberg equilibrium equation are:
1. The population of species must be very large.
2. There must be no migration and population must be isolated in a species.
3. There must be no mutations in a population of species.
4. There must be random mating, which means there are no mating preferences.
So, a population will not be according to Hardy-Weinberg Equilibrium if it is small, or there are , which is not raised, but mutations are expected to occur in future. Skunks can also migrate to another region of a woods despite the presence of a large mountain. As a result of possible mutations and migrations, the population is not in Hardy-Weinberg equilibrium.

does anyone know how to do this ? You are a bio-researcher on the planet Tawniwani, and you have been given the task of identifying and classifying the native fauna. Use this dichotomous key to identifyTawniwanian creature t.
A dichotomous key is a classification tool used to identify organisms based on morphological or behavioral characteristics. Individual C is a Roundus tricurlus.
What is a dichotomous key?
A dichotomous key is a significantly useful tool to classify organisms.
If you have an organism -or part of it- and you need to taxonomically identify it, you use a dichotomous key.
The key provides an easy and fast way for identification by describing different morphological or behavioral traits, leading you to the correct taxonomic classification.
The term dichotomous refers to how information is provided.
You will always have two options per feature (a and b, or 1 and 2), and you will have to choose one of them according to the characteristics of your organism.
Once you choose one of the options according to your organism, the key leads you to the following description, and you will have to choose one of the options again.
You will repeat this until you reach the name of your organism.
The key describes only specific traits that are useful for differentiation.
In the exposed example, for instance, we need to know the name of the individual C.
Step 1The first description is about the head size. The key asks you if the individual has a small or a large head. It has a small head, so the key tells you to move to description 2.
1a. Has a small head--------------------------- go to 2
1b. Has a large head--------------------------- go to 3
Step 2The second description is about the body shape. The key asks you if your organism has a narrow or a rounded body. And this individual has a rounded body, so the key tells you to move to description 7.
2a. Has a narrow body ------------------------ go to 6
2b. Has a round body -------------------------- go to 7
Step 3The seventh description is about antennae. Does your individual have curly or straight antennae? It has curly antennae. You have reached your organism's name. It is a Roundus tricurlus.
7a. Has a curly anteanne ------------------------ Roundus tricurlus
7b. Has a straight antennae--------------------- go to 8
Individual C is a Roundus tricurlus.

Answer:
number 3 is the central vacuole and its large, membrane-bound organelles found in plant cells that act as a storage space for water and other molecules in the cell
Explanation:
Answer:
3. Vacuole
Explanation:
Plant vacuole is a membrane (tonoplast) bound space which contains sap, water, excretory products and other materials (which are not useful for plants).
It occupies 90% of the volume of the plant cell. Tonoplast, in plants facilitates transport of ion into the vacuole (against the concentration gradient) which causes higher ionic concentration in vacuole than in the cytoplasm.Some other points:-
Amoeba have contractile vacuole for osmoregulation and excretory purposes. Some protists develop food vacuoles by engulfing food particles.Bill was really ill. he had salmonella food poisoning, which means he had __________, abdominal cramps, headache, vomiting, and diarrhoea. what main symptom of salmonella is missing from the list?
Answer:
Fever
Explanation:
Symptoms can last for seven days
Six hours to six days after infection, symptoms typically appear and continue for four to seven days. On the other hand, some people feel symptoms for a few weeks after infection, while others do not.
What cause salmonella to food poisoning?Infection with salmonella is typically brought on by ingesting raw or undercooked meat, poultry, eggs, or egg products, as well as by consuming unpasteurized milk.
The incubation period—also referred to as the latency period—can last anywhere from six hours to six days.
In addition to causing diarrhea, the acute inflammatory reaction can result in mucosal damage and ulceration. The germs have the potential to spread from the intestines and result in systemic illness.
Diarrhea, fever, and cramps are the most common symptoms of Salmonella infection.
Therefore, Symptoms can last for seven days.

Several bird species feed in a certain species of tree. each bird species feeds in a different part of the tree. which factor are the species of birds responding to in the environment?
a.) symbiosis
b.) competition
c.) parasitism
d.) omnivores
Competition factor are the species of birds responding to in the environment. Thus, the correct option is B.
What is competition?If numerous bird species eat on the same tree species, there will be fierce competition for food. As a result of the competition, each species will seek out a certain portion of the plant to feed on, most likely the part of the plant where it will be easiest to outcompete the competitors for food.
As a result, we may deduce that the right response is "They have evolved to diverse niches as a result of competition."

The graphs below show the changes in crab color at one beach from 1950 to 1990.
The change in crab color is an example of which type of evolution?
O A. Stabilizing selection, because one crab color was preferred over other colors.
O B. Stabilizing selection, because two crab colors were preferred over other colors.
O C. Directional selection, because two extreme colors were preferred over the more moderate color.
O D. Disruptive selection, because two extreme colors were preferred over the more moderate color.
O E. Adaptive radiation, because crabs of a single color evolved to form crabs of several colors.
The change in crab color is an example of Disruptive selection because two extreme colors were preferred over the more moderate color. Thus, the correct option for this question is D.
What is Natural selection?Natural selection may be defined as the selection of a few individuals from any given population according to their favorable variations.
In 1950, the crab color is in the form of stabilizing selection, while in 1990, it changes to disruptive selection that favors the two extreme colors over the intermediate one.
Disruptive selection occurs when environmental conditions changes in two different directions. Due to which variance increases in population.
Therefore, the correct option is D.
