Answers
Answer: True
Explanation:
The marine environment is associated with both biodiversity health and quality of water. The overfishing will not only harm the desired aquatic species but can also kill undesirable fishes and plant species which are removed from their habitat during the fishing process. The some fish species eat up the pollutants in water and sea debris making the environment clean and healthy for other aquatic species. Thus maintaining the fish population will preserve the aquatic environment.

byun walked 15 blocks in 25 minutes what was his average speed
Answers
Answer:
\(\frac{3}{5}\)blocks/minutes
Explanation:
Given parameters:
Number of blocks walked = 15blocks
Time taken for the walk = 25minutes
Unknown:
Average speed = ?
Solution:
In this scenario, the average speed is the rate of walking the blocks per unit of time;
Average speed = \(\frac{number of blocks}{time}\)
Input the parameters and solve;
Average speed = \(\frac{15}{25}\)blocks/minutes
Average speed = \(\frac{3}{5}\)blocks/minutes

What is one function of the structure labeled Y?
digest prey
pump blood into the heart
remove carbon dioxide from blood
capture prey
Answers
One function of the structure labeled Y is to pump blood into the heart.
The correct option is B.
What is the structure labeled Y in the snail?Structure Y refers to the pericardial cavity which surrounds the heart in snails.
The pericardial cavity plays an important role in the circulation of hemolymph, the snail's equivalent of blood. It functions as a chamber that receives and stores oxygenated hemolymph from the gills and pumps it into the heart, which then distributes it throughout the rest of the body.
Therefore, option "pump blood into the heart" is the correct function of structure Y. Option "digest prey" is not related to the structure Y in snails, and option "remove carbon dioxide from blood" and "capture prey" are not relevant to the circulatory system of snails.

Analyze the given diagram of the carbon cycle below.
An image of carbon cycle is shown. The sun, a cloud, two trees, one towards left and the other towards right, an animal, lake, and a factory are included. Arrow A points from the sun to the left tree. Arrow B points from the air above the clouds to the left tree. Arrow C points from the factory towards the air above the clouds. Arrow D points from the air to the lake labeled Carbonates in Water. Arrow E points from the label Dead Organism under the animal to label Fossils and Fossil Fuels. Arrow F points from the right tree to the air.
Part 1: Which process does arrow F represent?
Part 2: Explain how matter is conserved during the process.
Part 3: Justify why this process is a recycling of carbon in the carbon cycle.
Answers
The answers include the following below:
The process F means oxygen from plant goes into the atmosphere.Matter is conserved in this process because plants take carbon dioxide from the atmosphere for photosynthesis then produces oxygen into the atmosphere and then animals feed on plants and their faeces is released into the soil for plants use which is how it is conserved.This is because absorb light energy and convert it to chemical energy and plants absorb carbon dioxide which is exhaled by humans and animals in a cyclic manner.What is Carbon cycle?This is referred to as the circulation of carbon in various forms through nature and involves various processes such as photosynthesis, respiration etc.
The process F which points from the right tree to the air means that oxygen from the plant goes into the atmosphere after the process of photosynthesis and is then used by animals.

What prevents organisms from reproducing an unlimited number of offspring?
Answers
The primary reason living organisms cannot produce an unlimited number of offspring is senescence, otherwise known as old age.
Cells of the reproductive organs divide and continually make it possible for organisms to reproduce. As time goes on, the old cell dies and new cells replace them through mitotic or meiotic cell division of young cells that still has the ability to divide.
However, as programmed cell deaths occur with old age, the reproductive cells start losing the ability to divide, and when this happens, the ability for organisms to reproduce becomes limited.

For the Haber process, N2 + 3H2→2NH3, what theoretical volume of ammonia (NH3) should be produced if we start with 5.0L of N2 if STP?
44.8 L
22.4 L
10.0 L
29.9 L
Answers
For the Haber process, N2 + 3H2→2NH3,10.0 L is the theoretical volume of ammonia (NH3) should be produced if we start with 5.0L of N2 if STP. Therefore, option C is correct.
What is the Haber process ?In the Haber process, “the atmospheric nitrogen (N2) is changed to ammonia (NH3) by reacting it with hydrogen (H₂)”. A metal catalyst is used and high temperatures and pressures are maintained.
The balanced equation for the reaction is as follows:
N₂(g) + 3H₂(g) ⇾ 2NH₃(g)
From the balanced equation,
1 L of N₂ reacted to produce 2 L of NH₃ at STP
From the above information, we can obtain the volume of ammonia, NH₃ produced from 5.0 L of N₂ at STP. Details below:
From the balanced equation,
1 L of N₂ reacted to produce 2 L of NH₃ at STP
Then,
5.0 L of N₂ will react to produce = 5.0 × 2
= 10.0 L of NH₃ at STP
Thus, option C is correct

From the analysis of the 2 equations: X = 3/4 and Y = 5/4
Solving simultaneous equationsThe equations can be solved using subtracting one of the two equations from the other.
Let's label the two equations:
Y=3x-1 .................... equation 1
Y=2-X..................... equation 2
Equation 2 can be rearranged such that:
Y = -X+2
Subtracting equation 2 from 1:
Y=3x-1
Y = -X+2
0 = 4X -3
4X = 3
X = 3/4
Substitute X = 3/4 into any of equations 1 or 2 to determine Y.
Y = 3(3/4) - 1
= 9/4 - 1
= 5/4
Hence X = 3/4 and Y = 5/4

A crane has a sharp and pointed beak while the duck has a flat beak.Explain why
Answers
Answer:
The crane has a sharp and pointed beak adapted for catching and grasping prey. The sharp beak allows the crane to effectively stab and pierce its prey, such as fish, frogs, or small animals. The pointed shape helps the crane to accurately target its prey and secure a firm grip.
On the other hand, the duck has a flat beak, which is better suited for its specific feeding habits. Ducks are primarily filter feeders, and their flat beak enables them to sift through water or mud to collect small organisms, insects, and plants. The flat beak acts like a sieve, allowing the duck to strain out food particles while retaining water.
The difference in beak shape between the crane and the duck reflects their distinct feeding strategies and ecological roles. Each species has evolved its beak shape to optimize its ability to capture and consume the specific types of food sources available in their respective habitats.

4. The ATP yield from 2 moles of mitochondrial NADH under aerobic conditions in a eukaryotic cell would be: which option is correct a) 1 mole of ATP b) 2 moles of ATP c) 3 moles of ATP d) 4 moles of ATP e) 6 moles of ATP
Answers
The ATP yield from 2 moles of mitochondrial NADH under aerobic conditions in a eukaryotic cell is approximately 4 moles of ATP.
During oxidative phosphorylation, each mole of NADH can generate around 2.5 to 3 moles of ATP. Therefore, for 2 moles of NADH, the total ATP production would be in the range of 4 to 6 moles of ATP. While the more precise estimate falls within the 4 to 6 moles range, the closest option provided is 4 moles of ATP. It is important to note that the exact ATP yield can vary depending on factors such as the efficiency of the electron transport chain and the specific conditions within the cell.Since there are 2 moles of mitochondrial NADH, the total ATP yield would be around 4 to 6 moles of ATP. However, the most accurate option among the given choices is 4 moles of ATP.
