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.
Design a plan that can be used by oil workers everywhere to save ecosystems
Answer:
Oil workers activities involved in the exploration of crude oil and natural gas creates pollution which affects the ecosystem negatively. The various pollutions cause the death of plant and animal life both on land and in water bodies.
The oil workers should be more careful in their activities to prevent oil spillage as much as possible and if there is any at all then there should be adequate measures in the cleaning it up efficiently through biological and harmless chemicals.

Round the number 14.587020 to 4 significant digits. a. 14.59 b. 14.58 c. 14.587 d. 15.00 Please select the best answer from the choices provided A B C D
Answer:
A. 14.59
Explanation:
Firstly, rounding a number means making a number simpler but keeping its value close. So rounding 14.587020 means making it look less complex but making sure the rounded value is within range of the original value.
Next, we have to know that to round a number;
* Digits below 5 (<5) rounds down the next digit to their left i.e. we leave the digits the same and turn the rounding digit to 0.
* Digits above 5 (>5) rounds up the next digit to the left i.e. we add 1 to the next digit
Next, to round to 4 significant digits means we want to see only the first four non-zero digits in our value. Note that, all non-zero digits i.e. 1-9 are significant
Hence, 14.587020 will be:
= 14.587020
= 14.58700
= 14.59000
We have four (4) digits which are non-zero already, hence we stop here and remove all zeros to the right
Hence, 14.587020 to 4 significant digits is 14.59 i.e. 14.587020 ~ 14.59

a.14.59

What would be the mRNA base sequence formed from ACC CTG GTA GCT
Answer:
Explanation:
DNA utilizes four bases, adenine (A), guanine (G), cytosine (C), and thymine (T), in its code. RNA also uses four bases. However, instead of using 'T' as DNA does, it uses uracil (U). Therefore, if your DNA sequence is 3' T C G T T C A G T 5', the mRNA sequence would be 5' A G C A A G U C A 3'.
In which squares should the phrase “Yellow pods” appear?
The given question is incomplete however the correct question and the flow chart is related to the question as follows:
The flowchart below shows the three generations of a cross between a pea plant that has yellow pods and a pea plant that has green pods. yellow pods are the dominant trait. The flowchart is missing the labels that describe the traits.
In which squares should the phrase “yellow pods” appear?
1. A and D
2.B and E
3. A, C, and D
4. A, B, C, D, and E
Answer:
The correct answer is: 3. A, C, and D
Explanation:
According to Mendel’s laws of inheritance, when a plant with the dominant trait is crossed with a plant with a recessive trait, as a result, the dominant phenotype appears in all the F1 offspring. On Self cross F1 offspring, produces F2 offspring with dominant and recessive traits.
In the given scenario, pea plant with ‘yellow pods’ are dominant and pea plant with ‘green pods’ is recessive.
Therefore, when pea plant with yellow pods is crossed with the pea plant with the green pod, the F1 offspring (C) produced are with yellow pods.
Thus, parent (A) is with yellow pods and F2 offspring (D) is with yellow pods.

How many chemical bonds can each carbon atom form?
Answer:
It has four valence electrons, which it can achieve a full outer energy level which forms four covalent bonds. When its bonds only with hydrogen, it forms compounds which is called hydrocarbons. Carbon can be form in single, double, or triple covalent bonds with other carbon atoms.
Explanation:
The valency of carbon is four. Therefore, carbon can form four chemical bonds.
What is a chemical bond?It is the attraction between two atoms, they share or exchange electrons to form molecules or compounds is known as a chemical bond. They share electrons to fulfill their valency. The number of bonds depends on the number of valencies.
There are three types of bonds and that are covalent, ionic, and metallic bond. A covalent bond or molecular bond is formed by sharing of electrons, it occurs in non-metals. Ionic bonds are formed by exchanging electrons, it occurs in both metal and non-metal. metallic bonds are present between two metals. The covalent bond is the strongest bond.
There are four valencies in carbon. Therefore, it can make four bonds.

Explanation:
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

Answer:
Due to the movement of surounding water ijnto the cell.
Explanation:
A red blood cell placed in distilled water will swell and burst due to the movement of - water molecules moving by osmosis into the cell.
Osmosis is the movement of water that diffuses from a higher water concentration area to a lower water concentration area.
The distilled water outside the red blood cell, since it is 100% water and no salt, is hypotonic to the red blood cell.The red blood cell will gain water, swell ad then burst.Thus, a red blood cell placed in distilled water will swell and burst due to the movement of - water molecules moving by osmosis into the cell.
