Answer:
Fine focus.
Explanation:
If you're referencing a microscope, then it would be fine focus. Coarse focus is a basic focus used to properly see a specimen, while fine focus enhance clarity and precision. To use both, you have to gently twist a knob until you can see the specimen at a desired clarity.

explain the difference between gills and lungs. Give examples of animals that have only gills, animals that have only lungs, and animals that have both gills and lungs. What are the advantages of having gills, having lungs, and having both?
Answers
Answer:
Gills and lungs differentiate in many ways most certainly when it comes to breathing. Gills are used by aquatic animals such as; sharks, fish and octopi. Lungs on the other hand are mainly used by mammals such as; humans, dogs and hamsters.
Lungs help breathe in air for oxygen and gills help breath in the oxygen contained in the water.
There's many advantages you could have with breathing through gills and lungs, you could swim under water for much longer periods of time and you could obviously walk on land and easily breath the air.
Sorry this took so long to write, I do hope this helped!
Good luck!
Lungs : are used to breath above water
Gills eg: fish
Lungs eg: human’s, lions etc
Animals that have both gills & lungs eg: frog , lungfish etc
Advantages are
Having lungs : can breathe on land
Having gills : can breath in water
Having both : can breath on land and in water

6. Using fan -
7. Watering the plants -
8. Sweeping -
Answers
1. Using a glass when brushing teeth: By using a glass instead of leaving the tap running while brushing our teeth, we can conserve water. Freshwater is a finite resource, and reducing unnecessary water usage is essential for preserving our water supplies and ensuring their availability for both humans and the natural environment.
2. Hanging clothes: Opting to hang clothes to dry instead of using a dryer not only saves energy but also reduces greenhouse gas emissions. Clothes dryers consume a significant amount of electricity, and by utilizing natural methods like hanging clothes, we can contribute to reducing our energy consumption and lowering our carbon footprint.
3. Walking: Walking instead of using vehicles for short-distance travel offers multiple benefits. Firstly, it helps reduce air pollution by decreasing the emission of harmful gases from vehicles. Secondly, walking promotes personal health and well-being, as it is a form of physical exercise. Lastly, choosing to walk reduces traffic congestion and saves fuel.
4. Feeding stray animals: Feeding stray animals is an act of compassion and kindness. By providing food for stray animals, we help prevent their starvation and promote their overall welfare. It also reduces their need to hunt for food in natural habitats, preserving the delicate balance of local ecosystems.
5. Using the back page of paper: Utilizing both sides of a piece of paper helps reduce paper waste and conserves valuable forest resources. Paper production involves cutting down trees, and by maximizing the use of each sheet, we minimize the number of trees required to produce paper products.
6. Using a fan: Using a fan instead of an air conditioner helps reduce energy consumption and lowers greenhouse gas emissions. Air conditioners consume a significant amount of electricity, and by using fans to circulate air and provide cooling, we can contribute to conserving energy resources and mitigating the impact of climate change.
7. Watering the plants: Watering plants is essential for their growth and well-being. By providing them with adequate water, we support their ability to photosynthesize, produce oxygen, and contribute to a healthy ecosystem. Additionally, practicing responsible watering techniques, such as using watering cans instead of hoses, helps conserve water resources.
8. Sweeping: Sweeping instead of using a leaf blower or a hose to clean outdoor spaces reduces energy and water consumption. Leaf blowers and hoses consume significant amounts of electricity and water, respectively. Sweeping not only saves resources but also minimizes noise pollution and prevents soil erosion caused by high-pressure water flow.
Engaging in these activities of conserving natural resources demonstrates our commitment to environmental stewardship and sustainable living. By making conscious choices in our daily lives, we can contribute to the preservation and protection of the Earth's ecosystems for the benefit of current and future generations.

A. increased competition for fewer food sources B. organisms that are less suited to changes in the environment C. easier reproduction for organisms D. a higher economic value
Answers
The changes that this kind of low biodiversity would bring to an ecosystem would include increased competition for fewer food sources, organisms that are less suited to changes in the environment, and easier reproduction for organisms in A, B, and C.
What is biodiversity?Increased competition for fewer food sources, such as with only one species of tree, means that the organisms that depend on it for food and habitat would have to compete for limited resources. This can lead to a reduction in the overall population and diversity of the organisms in the ecosystem. Low-biodiversity ecosystems are less resilient to environmental changes, such as climate change or natural disasters. With only one species of tree, the organisms in the ecosystem would be less adaptable to changes in the environment and more vulnerable to extinction.
Hence, the changes that this kind of low biodiversity would bring to an ecosystem would be increased competition for fewer food sources, organisms that are less suited to changes in the environment, and easier reproduction for organisms in A, B, and C.

D) Auxins cause plant cells to shrink on one side making it less heavy, which tips the plant on the other side.
Answers
Answer:A) Auxins make plant cells grow larger towards the light causing it to bend.
Answer:
A.
Auxins make plant cells grow larger towards the light causing it to bend.
Explanation:
The auxins go more in the shady side, and that is why there are more auxins in the shady side, but in the illuminated side, there are less auxins. That will cause a bend in the growth of the plant towards the light source because the shady side has more auxins to make it grow. This is the reason why when there are auxins in a plant, they start to grow towards light.

Explanation:
Cloning is a type of biotechnology that involves the creation of genetically identical copies of an organism. It can be achieved through various techniques, such as somatic cell nuclear transfer (SCNT), where the nucleus of a somatic cell is inserted into an egg cell, and the resulting embryo is implanted into a surrogate mother.
One benefit of cloning for the individual is the potential to overcome infertility or genetic disorders. Cloning offers a reproductive option for individuals who are unable to conceive naturally or have a high risk of passing on inheritable diseases.
By cloning, they can have genetically related offspring without the risk of transmitting harmful genetic conditions. On the other hand, a risk associated with cloning for the individual is the potential for physical abnormalities and health issues.
Cloning has been shown to result in a higher incidence of developmental abnormalities and genetic defects in cloned animals. This poses a significant risk to the cloned individual, as they may suffer from health complications or reduced lifespan.
It also raises concerns about health complications, ethical implications, and ecological consequences. Careful consideration and regulation are necessary to ensure that cloning is used responsibly and ethically, weighing the potential benefits against the associated risks.
