What is the effect of…
…on…
Answer:
what is the effect of food availability/competition on natural selection
Explanation:
Something along those lines, this is similar to the Galapagos finches when there used to be just one species but due to natural selection and limited food due to competition, the beaks changed to be able to eat the other food s available that they originally could not eat. There are now about 14 due to this.

Explanation:
5. If there is a large number of prey rodents, the number of owls will increase due to a healthy
food source. More owls feeding on the rodents will cause their population to decrease, which in
turn will eventually cause the owls number to decrease. Would you expect to find this pattern in other ecosystems between predators and prey? Explain.
Answer:
Yes
Explanation:
One would expect to find the same pattern in any other ecosystems between predator and prey unless there is a way the prey's population is being replenished.
When predators start hunting down preys, the population of preys start decreasing and this will in turn means less food for the predators. If the trend continues, competition for food become fierce among the predators and this will make their population to start decreasing as the competitively strong ones take over the little food that remains and the competitively weak ones are gradually left to starve to death.

Most scientists agree that saturated fats contribute to high levels of “bad” cholesterol, while monounsaturated fats and polyunsaturated fats lower this type of cholesterol. The table below shows data about fats in some common foods.
Food (14 g) Saturated fat (g) Monounsaturated fat (g) Polyunsaturated fat (g)
Canola oil 1.0 8.9 3.9
Margarine 1.6 5.4 3.4
Olive oil 1.9 9.9 1.4
Lard 5.0 5.8 1.4
Butter 7.9 3.7 0.5
Joyce and Linda are identical twins who are 50 years old and enjoy exercising daily. Joyce avoids eating any dairy or animal products and eats granola made with canola oil for breakfast. Linda prefers rich foods, and eats bacon, eggs, and buttered toast each morning. Which statement describes a logical inference that can be made from the provided information?
a)Butter has higher levels of saturated fats in it than canola oil.
b)Linda and Joyce both have high levels of “bad” cholesterol.
c)Butter contains a small amount of polyunsaturated fats.
d)Linda has a higher level of “bad” cholesterol than Joyce.
Answer: D: Linda has a higher level of "bad" Cholesterol than Joyce
Explanation: From the first sentence Saturated fat contributes to high level of bad cholesterol. Buttered food, bacon ( Lard) are significantly high in saturated fat which contributes to high level of bad cholesterol and that's what Linda is eating. Joyce on the other hand avoids animal products and feeds on granola from Canola oil which is low in saturated fat.
The logical conclusion base on this diet is Joyce has low level of bad cholesterol while Linda has high level of bad cholesterol

4. If you are male, which member of your family should you look at to tell whether you are going to
go bald? Why? Use a punnett square to prove your answer.
Answer:
Your mother
Explanation:
If you are a male, the member of the family you should look at to tell whether you are going to go bald is your mother.
Baldness is a sex-linked recessive trait and as such, the two X chromosomes in females need to carry the allele in order for females to be phenotypically affected for the disorder. The males having only one X chromosomes however, means that they only need that single X chromosome to carry the baldness allele in order for them to be affected for baldness.
Assuming the allele for baldness in represented by b. Your mother is affected for baldness while your father is free from the disorder. This means that the genotype of your mum would be [tex]X^bX^b[/tex] while that of your dad would be [tex]X^BY[/tex]. According to law of inheritance, males usually inherit their X chromosomes from their mother. This means that any male your mother gives birth to would have the genotype [tex]X^bY[/tex] which phenotypically means that they will be affected for baldness.
The attached image shows the Punnet's square analysis of what will happen during inheritance.

A semipermeable membrane has a 2 percent salt solution on one side and a
15 percent salt solution on the other side. What will most likely occur?
A. Osmosis of water from a low concentration of salt to a high
concentration
B. Osmosis of water from a high concentration of salt to a low
concentration
c. Active transport of salt until all the salt is concentrated on one
side
D. Facilitated diffusion of salt until both concentrations are equal
Answer:
A
Explanation:
Water naturally travels from a low solute concentration to a high solute concentrated.
The correct answer is B. Osmosis of water from a high concentration of salt to a low concentration. This is due to the process of osmosis, which is the movement of water molecules from an area of low solute concentration to an area of high solute concentration.
What is the context of it ?In this case, the high salt concentration is on one side of the semipermeable membrane and the low salt concentration is on the other side. Therefore, water molecules will move from the side with a higher salt concentration to the side with a lower salt concentration, resulting in the osmosis of water from a high salt concentration to a low concentration.
The other options are incorrect because they do not accurately describe the process that occurs. Option A is incorrect because it states that osmosis will occur from low to high concentration, which is the opposite of what occurs in this situation.
Option C is incorrect because active transport requires energy and is used to move molecules against a concentration gradient, which is not happening here. Option D is incorrect because facilitated diffusion does not require energy and is used to move molecules down a concentration gradient, which is not happening here.

b) an increase in the number of frogs
c) no population change in any of the three species
Answer:
1. c) prey-predator
2. a) competition between lizards and frogs for food
Explanation:
1. Frogs feeding on small insects in the region shows prey-predator relationship. Predators are the dominating organism which kill weak organism for food and preys are the organisms which are killed. Here, frogs are the predators and small insects act as prey.
2. Introduction of lizards in the same region will increase the competition between lizards and frogs as their food is same that is small insects. Both frogs and lizards have same source of food (small insects), so lizard and frogs will fight for the same food.
Hence, the correct answers are 1. c) prey-predator
2. a) competition between lizards and frogs for food .

organisms. Describe one example of this kind of activity.
Answer:
Deforestation is one major human activity that harms both people and organisms. Cutting down trees lowers Earths ability to create fresh air, which leads to more toxic and polluted areas that can cause problems with breathing and even lead to lung cancer. Deforestation can harm other organisms because many animals such as birds, squirrels, and owls, look to the trees for a habitat. However, as we destroy they can cause a decrease in population which leads to an even bigger problem in the food chain.
