Facilitated diffusion uses ATP and requires a carrier protein; active transport does not.

Answers

Answer:

Active transport uses ATP and moves substances against the concentration gradient; facilitated diffusion does not.

Explanation:

Active transports moves against the concentration gradient (hence why it needs energy or ATP to do so, its going "against the grain"). Facilitated diffusion does not require ATP but does something require carrier proteins during passive transport.

2. What are 3 examples of lipids and what functions do they serve in organisms' bodies?

Answers

Answer:

Examples of lipids include fats, oils, waxes, certain vitamins

The functions of lipids include storing energy, signaling, and acting as structural components of cell membranes.

Which of the following is NOT one of the functions of lipids?

A. forming the exoskeletons of insects
B. forming waxy leaf coverings
C. storing energy in fat cells
D. forming cell membranes ​

Answers

Answer:

A function that is not characteristic of lipids is forming the exoskeleton of insects.

Explanation:

The exoskeleton is a rigid external structure that provides support and protection to animals such as insects.

The structure of exoskeletons is formed, especially in insects, by chitin. Chitin in turn is made up of N-acetyl-glucosamine, which when polymerized forms the hard and resistant layer that forms the external cover of the insects. Exoskeletons do not contain lipids in their composition.

The other options are correct with respect to the function of the lipids:

    B. Hydroxy fatty acid form the waxy layer that covers the leaves of the plants.

    C. Lipids are a reserve energy source, stored in the fatty cells.

    D. Phospholipids are the main component of cell membranes.

Summarize how a single change at cellular level can impact the entire body

Answers

Answer: A single change at a cellular level can change the way our entire body reacts, functions, and develops. Maintaining homeostasis is vital for our bodies to preform its necessary functions, without constant balance our bodies are unable to properly preform consequently, resulting in sickness and even death.

Explanation:

I used my biology book.

The body has different levels of organization based on structures and functions. The cellular level is the smallest and the basic level of the organization that consists of cells that are capable of division.

A single change at a cellular level can impact the entire body as:

Cellular levels consist of cells of different shapes, sizes and functions. Similar cells make up the tissue to perform functions.

A single change can alter the homeostasis of the cell and can bring about a larger impact on the body organization as maintenance of temperature is very important for the living process.

The whole body depends upon the cells for instructions of the growth, functioning, signalling and transportation.

Therefore, a single change at the cellular level can alter the entire body.

Which domain includes organisms that are called extremophiles (organisms which live in extreme environments)?

Answers

Answer: archaea

Explanation:

Most extremophiles are microorganisms (and a high proportion of these are archaea), but this group also includes eukaryotes such as protists (e.g., algae, fungi and protozoa) and multicellular organisms. Archaea is the main group to thrive in extreme environments.

Archaea domain includes organisms that are called extremophiles (organisms which live in extreme environments).

What are the characteristics of archaea?

Archaea is a domain of single-celled organisms. These microorganisms lack cell nuclei and are therefore prokaryotes. Archaea were initially classified as bacteria, receiving the name archaebacteria.

The common characteristics of Archaebacteria known to date are these: (1) the presence of characteristic tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan cell walls, with in many cases, replacement by a largely proteinaceous coat.

If there is an overgrowth of another organism called Archaea, then the symptom picture can be very different. There can still be bloating, abdominal pain and cramping, but Archaea usually cause constipation, not diarrhea.

In diffusion, the net movement of a substance travels down its concentration gradient
Explain using the image below.

Answers

Answer:

The diagram is a representation of the diffusion.

Explanation:

In this image, there are molecules or concentrations of a particular substance is represented by the purple circle on both sides of the box in left side concentration is higher than the right side.

So the movement of these molecules is from the left corner to the right down the concentration gradient, this type of movement of the substance is known as the diffusion which moves from high concentration to low concentration.

Diffusion is the movement of molecules from the higher concentration to lower concentration.

Diffusion is the movement of molecules from the area of higher concentration to the area of lower concentration. In the image, higher concentration of molecules are present on the left side whereas lower number of molecules are present on the right side of the image.

So here diffusion occurs by movement of molecules from higher concentration to lower concentration means from left to right side of the image until the concentration becomes equal so we can conclude diffusion is the movement of molecules from the higher concentration to lower concentration.

Sodium + water → sodium hydroxide + hydrogen

2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g)

Sodium hydroxide is an alkali. It is a base that dissolves in water to form an alkaline solution. This solution:

has a pH greater than 7

turns universal indicator solution blue or purple

Hydrogen gas is also produced. With very reactive metals such as potassium, the energy of the reaction causes the hydrogen to burn as the reaction takes place.

What type of electron is available to form bonds?

Valence electrons are the electrons in the outermost energy level or shell of an atom. These electrons are involved in the formation of chemical bonds between atoms.

Valence electrons are responsible for determining the chemical properties and reactivity of an element. When atoms come together to form chemical bonds, they do so by sharing, gaining, or losing valence electrons. The interaction of valence electrons between atoms allows for the formation of covalent bonds, ionic bonds, or metallic bonds, depending on the specific circumstances.

Therefore, valence electrons are crucial in the process of bonding between atoms.
