Answer:

a. sulfur

Explanation:

Sulfur is an example of a nonmetallic mineral

Non-metallic minerals are the minerals that do not contain metals, eg limestone, mica, coal etc. Such materials lack metallic characteristics like good electric and thermal conductivity, luster, rigor and malleability.

Sulfur is a non-metallic element with atomic number 16. It is considered as non metal because:

It is poor conductor of heat and electricity. Its density is lower than that of all metals. The electronegativity of sulfur is very high as compared to other metals. It is multivalent atom which is tasteless and odorless.

Heliocentric model  represents the copernican model that is most similar to that of Aristarchus

Aristarchus of samos was an ancient greek astronomer who proposed that the Earth revolves round the Sun, suggesting a heliocentric model of the solar system. However, his model did not gain widespread acceptance during his time and the geocentric model prevailed for many centuries.

The heliocentric model later reintroduced and developed by NIcolaus Copernicus in the 16th century. Heliocentric model placed the sun at the center of the solar system, with the planets, including Earth, orbiting around it.

In response to respiratory alkalosis d. the kidneys secrete more hydrogen ions.

Respiratory alkalosis is a type of medical condition produced when occurs the levels of carbon dioxide in the blood are too high, thereby changing the pH balance in the bloodstream and thus leading to different types of health problems associated with this uncontrolled acid-base balance.

Respiratory alkalosis medical condition is generally caused due to the process of hyperventilation during respiration, which is able t change the acid-base pH homeostatic balance (concentration of hydrogen ions) in the human body and thus alter the internal equilibrium condition.

Therefore, with this data, we can see that respiratory alkalosis is a well-known medical condition caused by hyperventilation which may be associated with the alteration of the pH acid-base balance in the body which may have serious health problems.

Fertilization results in the random combination of alleles from the gametes of each parent, leading to genetic variability in the offspring.

During fertilization, gametes from each parent combine to form a zygote, which then develops into an offspring with a unique combination of alleles. Because each parent contributes only one allele for each gene, the offspring can inherit different combinations of alleles from each parent, leading to genetic variability.

In the case of the Drosophila crosses performed by the students, the F1 flies all have the same phenotype because they each inherit one dominant allele and one recessive allele from the parents. However, in the F2 generation, the random combination of alleles during fertilization leads to the appearance of four different phenotypes, each with a different combination of dominant and recessive alleles.

This genetic variability is the result of the random assortment of alleles during gamete formation and the random combination of gametes during fertilization.

3) Provides most of the cells energy

Explanation:

The main functions of the mitochondria is to provide energy to most of the cells. Known as the (Powerhouses of The Cell), mitochondria produce the energy necessary for the cell's survival and functioning. Through a series of chemical reactions, mitochondria break down glucose into an energy molecule known as adenosine triphosphate (ATP), which is used to fuel various other cellular processes. Present in nearly all types of human cell, mitochondria are vital to our survival. They generate the majority of our adenosine triphosphate (ATP), the energy currency of the cell. Mitochondria are also involved in other tasks, such as signaling between cells and cell death, otherwise known as apoptosis

The order of the molecules from lowest to highest ability to pass through a phospholipid bilayer is: molecular oxygen, water, a sodium ion, glucose.

The ability of molecules to pass through a phospholipid bilayer depends on their size, polarity, and charge. Here's the order from lowest to highest ability to pass through a phospholipid bilayer:

1. Molecular oxygen (O2) - small and nonpolar, can easily pass through.
2. Water (H2O) - small and polar, can pass through but slower than molecular oxygen.
3. A sodium ion (Na+) - small but charged, has difficulty passing through without help from channels or transporters.
4. Glucose - large and polar, has the lowest ability to pass through without help from specific transport proteins.

So, the correct order is: molecular oxygen, water, a sodium ion, glucose.

Sustainable Development Goal #13, known as Climate Action, is a global initiative aimed at addressing the urgent challenges posed by climate change. It recognizes that climate change is one of the most pressing issues of our time and calls for collective action to mitigate its impacts and build resilience to future changes.

Climate Action encompasses various strategies and measures designed to reduce greenhouse gas emissions, promote sustainable practices, and adapt to the effects of climate change. Here are some key points to explain this goal:

Urgency and Scope: Climate change is a global phenomenon affecting all nations, ecosystems, and sectors of society. It poses significant risks to the environment, human well-being, and economic stability. Climate Action emphasizes the urgency of addressing these challenges to safeguard our planet and future generations.

Mitigation: One essential aspect of Climate Action is reducing greenhouse gas emissions responsible for global warming. This involves transitioning to cleaner and more sustainable energy sources, increasing energy efficiency, adopting eco-friendly practices in industries, promoting sustainable transportation, and preserving forests that act as carbon sinks.

Adaptation: Another crucial aspect is building resilience and adapting to the impacts of climate change. This includes developing strategies to protect vulnerable communities, infrastructure, and ecosystems from rising sea levels, extreme weather events, water scarcity, and other climate-related risks. It involves planning resilient cities, improving disaster preparedness, and implementing sustainable agriculture practices.

International Cooperation: Climate change is a global challenge that requires collective action. The Climate Action goal emphasizes the importance of international cooperation, collaboration between governments, private sector engagement, and involvement of civil society to achieve meaningful impact. Initiatives like the Paris Agreement aim to unite nations in their efforts to combat climate change.

Explanation:

Water will travel in a net direction into the cell when the concentration of the solute is lower outside the cell than inside the cell. Osmosis is the name of this process.

Water (solvent) always travels from a location with a higher concentration of solvent to a region with a lower concentration of solvent; in other words, water moves by osmosis from inside the cell to the outside, where the concentration of solutes is higher.

While osmosis naturally causes solvents to travel from the side of a membrane where the concentration is higher to the side where it is lower, reverse osmosis compels the solvent to flow in the other direction when pressure is applied.
