Describe one way that the functioning of plant cells is similar to the functioning of animal cells.
Answer:
One way in which the functioning of plant cells is similar to the functioning of animal cells is that they are both eukaryotic cells. This means that they both have membrane organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Moreover, these similarities in cellular structure help each cell function in a similar manner.
Which sequence represents the order of some events in human development?
(1) zygote → sperm → tissues → egg
(2) fetus → tissues → zygote → egg
(3) zygote → tissues → organs → fetus
(4) sperm → zygote → organs → tissues
Answer:
Answer is 3. Hope this helps!

A population of squirrels eats acorns from local oak trees. In some years, oak trees produce much greater
numbers of acorns than usual.
Which of the following is the most direct effect of an increase of acorns on the squirrel population?
Answers
A The population has fewer predators.
B The population size increases.
C The population expands its territory into new habitats.
D The population size decrease due to competition.
Answer:
B
Explanation:
The population size increases
A population of squirrels eats acorns from local oak trees. In some years, oak trees produce much greater numbers of acorns than usual. The most direct effect of an increase in acorns on the squirrel population would be: the population size would increase, which is option B.
When there is an abundance of acorns, the squirrel population can benefit from a readily available food source. With more food available, squirrels are better able to meet their nutritional needs and reproduce successfully. This leads to an increase in the population size as more squirrels are born and survive due to the abundance of resources.

The following are the steps listed in incorrect order to describe the process of energy transfer from the sun to the molecules that power the cellular processes of organisms. 1. Energy is stored in the form of glucose. 2. Energy from sunlight is absorbed by cells. 3. Energy is used by mitochondria to produce ATP. 4. Energy is released when ATP is broken down to ADP and P.5. Energy is released when glucose is broken down into pyruvate. Which of the following describes the correct order of this energy transfer process?
B. 2, 1, 5, 3, 4
C. 2, 4, 5, 1, 3
A. 3, 2, 1, 5, 4
D. 1, 4, 5, 1, 3
The correct order of this energy transfer process is as follows:
Energy is used by mitochondria to produce ATP. Energy from sunlight is absorbed by cells.Energy is stored in the form of glucose.Energy is released when glucose is broken down into pyruvate.Energy is released when ATP is broken down to ADP.Thus, the correct option is A, i.e. 3, 2, 1, 5, 4.
What is the Cellular process?The Cellular processes may be defined as those processes that occur in living organisms in order to regulate the communication between cell requirements and body utilization.
The initial step in the cellular process is that the energy is utilized by the mitochondria in order to construct ATP. Then, the energy is significantly absorbed by cells from the sunlight that later converts into chemical form as a product known as glucose.
Energy is further released when glucose is broken down into pyruvate and ATP is broken down to ADP.
Therefore, the correct order of energy transfer from the sun to the molecules that power the cellular processes of organisms is well described above.

Compare and contrast negative and positive feedback loops. Which one is more common? Why?
Answer:
Negative Feedback LoopsA negative feedback mechanism or loop is a pathway stimulated by the deviation in the output, which causes changes in output to the direction opposite to the initial deviation.The negative feedback mechanism moves the variable factors towards the stable state or homeostasis after the control unit interprets the extent of the deviation.Negative feedback loops are more common than positive ones as they tend to stabilize the system.The loop detects the change in output and acts in the opposite direction to nullify the stimulus causing the change.These loops are activated under two conditions; when the value of the variable is above the normal value and has to be brought down and when the value of the variable is below the normal values and has to be brought up.Negative feedback mechanisms occur as a part of homeostasis to bring the variables back to their normal levels by counteracting the stimulus, causing the deviation in the first place.Like in a positive feedback mechanism, a negative feedback mechanism also contains different components that together help to maintain a stable state.Examples of Negative Feedback Mechanism
1. Regulation of blood glucose level
2. Temperature regulation
Positive Feedback LoopA positive feedback mechanism, as the name suggests, is a pathway that in response to a deviation in the output causes the output to change even more in the direction of the initial deviation.A positive feedback mechanism amplifies the deviations and brings state changes to the output.Positive feedback mechanisms are far less common than negative feedback mechanisms as it moves the body away from homeostasis.The process of positive feedback mechanism progressively amplifies the response as long as the stimulus is continued.The positive feedback loop can consist of either a single component that activates its own activity or several components with direct and indirect interactions.Positive feedback loops in biological processes are often observed in processes that need to occur quickly and towards completion as the output tends to increase the effect of the stimulus.Positive mechanisms are very few within living systems like the human body, but these can also be observed in the ecosystem, like in the case of ripening of fruit.Examples of Positive Feedback Mechanism
1. Menstrual cycle
2. Childbirth
Negative feedback loops are more common than positive ones as they tend to stabilize the system.
Positive Feedback vs Negative Feedback (8 Key Differences)Definition
The positive feedback mechanism is a pathway that in response to a deviation in the output causes the output to change even more in the direction of the initial deviation. A negative feedback mechanism or loop is a pathway stimulated by the deviation in the output, which causes changes in output to the direction opposite to the initial deviation.Effect on the homeostasis
A positive feedback mechanism breaks down the homeostasis system of the body. A negative feedback mechanism works to maintain the conditions of homeostasis in the body.Occurrence
The positive feedback mechanism is less common and occurs in specific situations.The negative feedback mechanism is more common and occurs in different organs and systems in the body.Stability
The positive feedback mechanism is less stable.The negative feedback mechanism is more stable.Effect
In a system with a positive feedback mechanism, the effective input is increased by the addition of actual input with the feedback signal.In a system with a negative feedback mechanism, the effective input is decreased as the feedback signal inhibits the actual input.External interruption
A positive feedback mechanism might require an external interruption.A negative feedback mechanism doesn’t require an external interruption.Changes
Positive loops enhances the change in physiological factors.Negative loops resists changes in physiological factors.Examples
Positive feedback mechanism in nature is observed during childbirth in humans and during the ripening of fruits. The negative feedback mechanism is observed during thermoregulation and maintaining the blood glucose level.An oil mining company has started drilling oil offshore at a location. Thus far, it has benefitted the people by increasing employment opportunities in the area. Predict the most likely outcome the oil mine will have on the environment?
It will cause drying up of water in plants.
It will emit radiation which destroys plants.
It will produce greenhouse gases which pollutes soil.
It will contaminate the soil and water in the ocean.
Answer:
It will contaminate the soil and water in the ocean.
Explanation:
This is because the oil drilling will cause oil spillage on the soil and water in the ocean. The oil spillage will cover the oil and it will not allow plant to grow there. Any crops planted there will not grow because it had release chemical and act as covering which cannot support plant growth. When it is washed into the ocean or water bodies, it can lead to death if aquatic live because it will affect the amount of oxygen that will available to them.

Know how to calculate the amount of chromosomes in mitotic cells and in gamete cells, when given an amount of the chromosome number for one of the two types of cells. For example, a fruit fly has 8 chromosomes or 4 pairs of chromosomes in its wing cells, how many chromosomes will be in each egg cell?
Answer:
4 chromosomes
Explanation:
Meiosis is a kind of cell division that produces daughter cells that already have their chromosome number reduced by half. Due to this reason, meiosis is called a reduction division. A diploid parent cell (2n) will produce gametes with haploid cells (n).
According to this question, a fruit fly has 8 chromosomes or 4 pairs of chromosomes in its wing cells, after undergoing meiotic division, it will possess 4 chromosomes in each gamete cell. Note that the chromosome number has been reduced by half.

What is the difference between a predator and a parasite?
a) A predator has a lengthy relationship with its prey
b) A parasite does not immediately kill its host.
c) A predator does not immediately kill its prey.
d) A parasite has a brief relationship with its host.
The correct answer is b). A parasite does not immediately kill its host.
What is the difference between a predator and a parasite?
Predators are species that obtain energy by stealing it from other organisms, just like parasites do. Consequently, we have a relationship where one creature (the predator) benefits while the other organism suffers (the prey).
Because they only consume resources from one host, parasites differ from predators in that they do not consume a large number of prey. Schistosoma mansoni, a trematode parasite, is an excellent illustration of this. One human host is all that an adult schistosome parasite needs to survive. It won't ever slither out and infect another person.
Hence, the correct option b.
