Answer:it's the third option
Explanation:
Because animal cells don't have a cell wall or chloroplast
Going by the organelles seen under the microscope, the correct labelling of the slides would be:
Slide A - plant cells Slide B - animal cellsSlide A would be a plant cell because of the presence of cell wall and chloroplast. these 2 organelles are unique to the plant cell only.
Slide B would be an animal cell due to the absence of cell wall and chloroplast.
Both cells are eukaryotic cells with essentially the same organelles. However, the plant cell has chloroplast, cell wall, and large central vacuole while the animal cell does not.

Good management of the environment is based on
economics
duplicating nature
leaving the environment alone
stopping all changes in the environment
Good environmental management is a multifaceted approach that involves managing ecological processes, adapting to changing conditions, and implementing regulatory controls to ensure sustainability. It also includes economic strategies such as taxation to encourage conservation and sustainable use of limited resources.
Good management of the environment is not based on a single action or ideology. Instead, it typically involves a combination of practices that include continuously managing limiting factors and ecological processes, as well as being adaptive and minimally intrusive. This also means that good environmental management often depends on regulatory controls, such as natural resource management laws and pollution laws that define sustainable use and prevent harmful dumping into the environment.
Additionally, conservation biology principles guide efforts to maintain complex and adaptive ecosystems by ensuring that ecosystem processes like water cycling and nutrient cycling are maintained, external threats are minimized, and actions taken are adaptive to changing conditions. This approach is vital as it recognizes that the earth has a limited supply of resources, which must be conserved for present and future generations.
An economic perspective on environmental management might include implementing taxes on resource extraction and waste production to encourage conservation and sustainable practices. This is aligned with the idea that growth is not indefinitely sustainable, and human activities must align with natural laws to maintain the integrity of the environment.
Which statement is NOT supported by the theory of natural selection?
A) Organisms with common characteristics descended from a common ancestor.
B) Living things change through time.
C) When organisms compete for resources, those best suited to the environment survive.
D) Mutations in body cells are always passed to offspring.

Which of the following causes tidal waves?
Strong winds
Underwater earthquakes
Gravitational pulls of the sun and moon
Temperature difference between land and sea
Tidal waves, better known as tides, are primarily caused by the gravitational pulls of the sun and moon. They are not significantly influenced by strong winds or temperature differences between land and sea. Misuse of the term 'tidal wave' often leads to confusion with tsunamis, which are caused by underwater earthquakes or similar events.
Explanation:The primary cause of tidal waves, or more accurately, tides, is the gravitational pull of the sun and moon. This gravitational force causes the Earth's oceans to bulge out in the direction of these celestial bodies, creating a rise and fall in sea level that we experience as tides. However, it is important to note that terms like 'tidal wave' are often misinterpreted.
True tidal waves are relatively slow, predictable, and governed by astronomical factors. On the other hand, underwater phenomena like underwater earthquakes, landslides, or volcanic eruptions can cause sudden large waves known as tsunamis, which are often incorrectly referred to as 'tidal waves'. Strong winds and temperature differences between land and sea mainly influence surface wave activity and do not play a significant role in causing tidal waves.

What are the two ways that carbon enters into the atmosphere?
The carbon enters into the atmosphere through two ways that are burning of fossil fuels and by respiration of living organisms.
Fossil fuels are the fuels that are produced beneath the earth crust by degradation of the organic matter of dead and decaying plants, animals, and animal dung. Fossil fuels like coal, petroleum, and natural gas when burned or combusted liberate carbon dioxide gas into the atmosphere, which is a chief source of carbon element in the atmosphere. The respiration process takes place in all living organisms including humans, animals, and plants. The carbon dioxide is the chief gas produced in the respiration process. Again it is a source of carbon to the atmosphere.Learn more about carbon:

List the 6 steps in the food Flow system:
Answer:
There are 8 stages in the flow of the food through your
establishment:
1. Purchasing and receiving
2. Storage
3. Preparation (including defrosting)
4. Cooking
5. Cooling
6. Hot and cold holding
7. Reheating
8. Serving
Explanation:
Food flow system: Production, processing, distribution, preparation, consumption, waste management—ensuring a sustainable journey from origin to disposal.
The correct steps in the food flow system are as follows:
1. Food Production: This is the initial step where food is grown, raised, or harvested. It involves agricultural practices, aquaculture, and other forms of food cultivation.
2. Food Processing: After production, food may undergo processing, which can include slaughtering, butchering, and packing of animals; pasteurization of milk; or canning and freezing of fruits and vegetables.
3. Food Distribution: Once processed, food is transported from the place of production or processing to various distribution points such as warehouses, grocery stores, restaurants, and other food service providers.
4. Food Preparation: This step involves the preparation of food for consumption. It can occur in commercial settings like restaurants or at home. It includes cooking, seasoning, and assembling meals.
5. Food Consumption: This is the stage where food is eaten. It is the end goal of the food flow system, where nutrients from the food are taken up by the body.
6. Food Disposal/Waste Management: After consumption, there is usually some waste, which includes inedible parts of food, leftovers, and packaging. Proper disposal or recycling of these materials is an important part of the food flow system to minimize environmental impact.
These steps outline the journey of food from its origin to its eventual disposal, highlighting the importance of each phase in ensuring a sustainable food system.

Two guinea pigs are crossed, one parent is Ss, the other ss. What is the probability of a baby guinea pig from this cross having both S and s factors?
A.0% chance
B.25% chance
C.50% chance
D.75% chance
Answer: B. 50%
Explanation: Image attached
Final answer:
The probability of a baby guinea pig from the cross between parents with genotypes Ss and ss having both S and s alleles is C.50% chance, as demonstrated using a Punnett square.
Explanation:
The question involves calculating the probability of a baby guinea pig inheriting specific genetic factors from its parents, one with genotype Ss and the other with genotype ss. To find the probability of an offspring having both S and s alleles, we can use a Punnett square to represent the possible genetic combinations.
Place the alleles of the first parent (Ss) at the top of the Punnett square.Place the alleles of the second parent (ss) on the side of the Punnett square.Fill in the squares to show the possible allele combinations for the offspring.In this scenario, half of the offspring (50%) would inherit an S allele from the first parent and an s allele from the second parent, resulting in the genotype Ss. Therefore, the correct answer is C. 50% chance. This calculation demonstrates how genetic traits can be inherited and the importance of understanding Mendelian genetics.
