Tall oak trees are better able to compete for sunlight in crowded forests. short oak trees are at a
disadvantage. what type of selection appears to have made oak trees grow tall?
a. stabilizing selection
b. directional selection
c. disruptive selection
The type of selection that makes tall oka trees a better competitor for sunlight over short ones would be directional selection.
What is directional selection?It is a kind of natural selection in which individuals with traits at one extreme end of the population are better adapted to the environment.
In this case, tall and short oak trees are at the two extreme ends of the population mean with tall oak trees being able to better competitors for sunlight than the short ones.
The selection is, thus, directional, towards the tall trees rather than the average or the short ones.

11. Explain how territorial behavior helps an animal population survive.
Answer:
Innate
fight or flight
innate
hierarchy
Aggressive
Learned
habituation
trial and error
Circadian rhythm
migrate
When animals mark their territory they ensure that the mates and food in their area are not overwhelmed. Though territorial animals often fight, it is not to the death, and more to establish social order. This prevents them from over-eating their environment and helps the entire species stay in balance to survive.
Explanation:
A population of 1,000 squirrels live on a farm plot that has an area of 250 square feet. What is the population density?
Answer:
750 square feet
Explanation:
1,000-250=750
And this is the population density.
The population density is equal to 4 people/square feet.
What is the formula for calculating population density?The formula for population density is defined as the number of individuals divided by the area of land given.
Here, number of individuals = 1,000
Area of land = 250 square feet
So, 1000/250 = 4
Therefore, the population density is equal to 4 people/square feet.

Advantage: altering a component in the cell walls, causing the contents of the fungal cells to flow out and the cells to perish. inhibiting fungal cells from multiplying and expanding.
Disadvantage: An allergic response may cause swelling of your face, neck, or tongue, as well as breathing difficulties. a severe skin reaction, such as blistering or peeling. Loss of appetite, vomiting, nausea, jaundice, dark urine or pale feces, weariness, or weakness are all symptoms of liver impairment.
Antifungal medicines are used to treat fungal infections, which most commonly affect your skin, hair and nails.
You can get some antifungal medicines from a pharmacy without needing a GP prescription.
Some fungal infections can grow inside the body and need to be treated in hospital.
Antifungal medicines work by either:
killing the fungus
preventing the fungus from growing
Before taking antifungal medicines, speak to a pharmacist or GP about:
any existing conditions or allergies that may affect your treatment for fungal infection
the possible side effects of antifungal medicines
whether the antifungal medicine may interact with other medicines you may already be taking
whether your antifungal medicine is suitable to take during pregnancy or while breastfeeding – many are not suitable
You can also check the patient information leaflet that comes with your antifungal medicine for more information.

Five hundred cockroaches of one species were sprayed with a new insecticide. Twenty-four hours later nearly all the cockroaches were dead. A few, however, survived. This outcome illustrates which one of darwin’s key ideas about natural selection and variation?.
Answer:
This shows that over time, some insects can become "pesticide-resistant" meaning that pesticides don't affect them anymore. And this only happens every few generations. Therefore, each generation is being naturally selected and accumulating variations that make them resist the chemicals. This shows that each cockroach's genes are changing to give them variation from the rest of the population.

VOLUME
Why does the first method for determining volume work only for a regular-shaped object?
Will the second method for determining volume work for any object or just an odd-shaped one?
Why?
Is one method of measurement more accurate than the other? Why or why not?
Would the displacement method of measurement work for a cube of sugar?
What about a cork? Why?
What did you find out from this investigation? Be thoughtful in your answer.
.
Answer:
1. Because only regular-shaped objects have a consistent length, width, height, and shape. When dealing with an object composed of differing shapes, you must calculate each portion separately and then add them. For instance, if you have a swimming pool of two depths and want to determine cubic feet, you would have to calculate the volume for each section and then add them.
2. method used to figure the volume of an irregular shaped object Neither measurement is more "accurate" than the other--they simply denote different things. Length is a measurement of the distance between two points in space. The area is a measurement of the surface covered by a given shape.
3. not in the water as the sugar would dissolve if you could find a liquid that sugar does not dissolve in, then it would work

Energy in an ecosystem flows directly from _______. a. producers to tertiary consumers b. producers to secondary consumers c. tertiary consumers to secondary consumers d. secondary consumers to tertiary consumers please select the best answer from the choices provided a b c d
Answer:
A.
Explanation:
Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.
Energy in an ecosystem flows directly from producers to tertiary consumers. So, the correct option is A.
What do you mean by Ecosystem?An Ecosystem may be defined as an area where organisms of different species are present together in a given time and interact with one another in order to survive.
In an ecosystem, producers produce the energy in the presence of sunlight through the process of photosynthesis. And then passes its energy to primary consumers (herbivores), then primary consumer passes their energy to secondary consumers (carnivores), then secondary consumers pass their energy to tertiary consumers. According to Lindeman, only 10% of energy get transferred to each trophic level.
Therefore, Energy in an ecosystem flows directly from producers to tertiary consumers.

Looks like a recessive trait, since both halves of the shape needs to be filled to make the trait active.
The pedigree is explained in the image, and the male is represented by the square and the female is represented by the circle. Here is the sex linked recessive pedigree present in the image.
What does the pedigree explain?The pedigree explains the heritable pattern of traits, such as genetic diseases in males and females, as well as the chances of being diseased, such as with sex-linked recessive diseases, where males have a higher chance of being diseased than females. Here the image explains it is a sex-linked recessive disease because most females are carriers, which means they have a single copy of the recessive allele, but when they pass it on to their sons, they get fully diseased as they need a single recessive copy due to the presence of a single X chromosome.
Hence, the male is represented by the square, and the female is represented by the circle, and here is a sex linked recessive pedigree present in the image.

Smooth muscle cells look like smooth, single nucleate, and connected by gap junctions under the microscope. Thus, the correct option is C.
What are Smooth muscle cells?
Smooth muscle cells are also called as involuntary muscle cells. These muscle shows no cross stripes under microscopic magnification. Muscle cells are made up of narrow spindle-shaped cells with a single, centrally located nucleus. Smooth muscle tissue, unlike the striated muscle, contracts slowly and automatically in the body.
At a cellular level, smooth muscle cells can be described as an involuntary, non-striated muscle cell. Smooth muscle cells consist of alternate thick and thin filaments which are not arranged into sarcomeres however it gives a non-striated pattern. On further microscopic examination, it appears homogenous.
Therefore, the correct option is C.
