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

What groups of organisms are most in danger of extinction?
A. Those with small population
B. Those that migrate or need special habitats
C. Those with large populations that breed quickly
D. Both a and b
Explanation:
D.Both a and B
As organisms with small population and those who migrate and need special habitat are most in danger of extinction.
The group of organisms that are in danger of extinction is those that have small populations and those that migrate or need special habits. So the correct option is D.
What is the extinction of species?
In biology, extinction refers to the extinction or death of a species. Extinction happens when a species' numbers are reduced due to evolutionary changes in its members, such as genetic inbreeding, poor reproduction, and population decline, or due to environmental factors like habitat fragmentation, climate change, natural disasters, and overexploitation of the species for human use.
The majority of species that have ever existed on Earth have gone extinct, but the fossil record indicates five very significant extinctions, known as mass extinction events, each of which resulted in the extinction of enormous numbers of species. The bulk of extinctions, which happen continuously and are described as background extinctions, are separated from these glaring decreases in the variety by the term "mass extinction."
Therefore, the correct option is D.

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
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.

Animals and plants that are unable to adapt to their environment will become
A- Prey
B- A new species
C- Extinct
D- Hungry
I think A or C
Explanation:
It really depends on how the question is phrased. Animals and plants that are unable to adapt to their enviroment will become- Hold it right there. How long will they be unadaptable? Is this forever? If so then yes, they will definately become extinct. If this is for a short amount of time then no, they will become prey, but there is also the fact that yes, they will become hungry. Because if they are not adapted then how are they gonna know the best sports for grub? Same thing for plants, if they can't adapt to the climate, they cannot produce food for themselves. Basically, if its a simple question then forget about everything else. It's Prey, because animals that can't adapt to their enviroment are immedietly in danger. Now if this question has more to it then I would go for C. But overall Just go with prey for now.
What prediction can you make about softness of potassium and vigor of its reaction with water?
Answer:
Chemical properties of the alkali metals
Atoms of group 1 elements all have one electron in their outer shell. This means that the alkali metals all have similar chemical properties.
Reactions with water
The alkali metals react with water to produce a metal hydroxide and hydrogen. For example, sodium reacts with water:
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.
Explanation:
Answer:
potassium reacts rigorously with cold water. potassium is a soft metal. we can predict that potassium is a highly reactive metal.

What is the difference between facilitated diffusion and active transport?
Facilitated diffusion uses ATP and moves substances with the concentration gradient; active transport does not.
Active transport uses ATP and moves substances against the concentration gradient; facilitated diffusion does not.
Active transport uses ATP and does not require a carrier protein; facilitated diffusion does neither.
Facilitated diffusion uses ATP and requires a carrier protein; active transport does not.
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.

What differentiates passive transport from active transport?
Group of answer choices
Molecules move down a concentration gradient during passive transport.
Passive transport involves molecules moving across the cell membrane.
ATP is needed for passive transport to occur.
Proteins have a role in passive transport.
Answer:
The movement of molecules across a membrane without the input of energy is known as passive transport. When energy (ATP) is needed, the movement is known as active transport. Active transport moves molecules against their concentration gradient, from an area of low concentration to an area of high concentration

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