Explanation:
If an organism is multicellular, it probably has
A.) Prokaryotic cells
B.) Eukaryotic cells
C.) Cancer cells
D.) All of the above
Answer:
B. Eukaryotic cells
Explanation:
Prokaryotic cells are only seen in unicellular organisms as bacteria and cancer cells are just cells where there has been an error in division or a mutation.
If an organism is multicellular, it probably has - option B.) Eukaryotic cells.
Cells are of mainly two types prokaryotic cells and eukaryotic cells. The main difference between eukaryotic and prokaryotic cells is that:
Eukaryotic cells have a nucleus in which genetic material is stored enclosed by a nuclear membrane.All prokaryotic cells only form single-celled (unicellular) organisms without a true nucleus or membrane-bound structures, examples of prokaryotes are bacteria and archaea. Organisms with eukaryotic cells are called eukaryotes that can be either multicellular such as animals, plants, fungi, and protists, or single-celled as well. So, all multicellular organisms are eukaryotes..Thus, If an organism is multicellular, it probably has - option B.) Eukaryotic cells.

What is the impact of the depletion of fishing stocks?
Answer:
Decades of destructive fishing has resulted in the precipitous decline of key fish stocks such as bluefin tuna and Grand Banks cod, as well as collateral impacts to other marine life. Hundreds of thousands of marine mammals, seabirds, and sea turtles are captured each year, alongside tens of millions of sharks.

Answer:
C. Guanine
Explanation:
A pairs together with T, or U in RNA,
and C and G always pair together.
Answer:
The answer is C. Guanine
Explanation:
Pyrimidines always bond with purines. Since Cytosine is a pyrimidine, it must bind with a purine, which can either be Adenine or Guanine. However, Adenine has only 2 places for hydrogen bonding while Guanine has 3. Since Cytosine also has 3, it would bind to Guanine. GCAT is a useful acronym for remembering which binds to which.
This stadium can hold 100,000, or 1x10, people. The
number of atoms in a grain of iron is about 1x 1016,
Would you need 1 x 10° or 1 x 10' stadiums to hold
the same number of people as the number of atoms in
a grain of iron? Explain your answer,
Answer:
1 x 10^13 stadiums will be needed in this scenario
Explanation:
We are told that
1 stadium holds = 1 × 10^5 people and
Number of iron atoms = 1 × 10^18 atoms
If the stadium carries an equivalent number of atoms as that of people.
We can infer that 1 stadium will carry 1 × 10^5 atoms.
The calculation to determine the number of stadiums would then be 1 × 10^18 divided by 10^5 atoms/stadium which was gotten by dividing the total number of atoms by the number of atoms per stadium.
Number of stadiums = Total number of atoms ÷ Number of atoms per stadium
= 1 × 10^18 atoms ÷ 1 × 10^5 atoms/stadium
= 1 × 10^13 Stadiums
This means that 1 × 10^18 atoms would occupy 1 × 10^13 stadiums
Explain how dysfunction at one level of organization impacts other levels and provide an example.
Answer:
Please find the explanation below
Explanation:
All living organisms are made up of four level of organizations namely: cell, tissue, organs, organ system and ultimately, the organism. These levels of organization are interrelated in such a way that CELLS accumulate to form TISSUE, TISSUES accumulate to form ORGAN, ORGANS accumulate to form ORGAN SYSTEM.
Since one level is dependent on a lower level, a dysfunction in one level will cause the dysfunction of another level. For example, a dysfunction in LIVER CELLS will cause the LIVER TISSUES formed from the cells to be dysfunctional. This dysfunctionality will extend to the LIVER as an organ and cause issues in the EXCRETORY SYSTEM (an organ system that constitutes the liver organ).

low mutation rate
genetic diversity

Small population is the answer
Your welcome
According to the Charles darwin theory of natural selection, genetic diversity best allow a species to survive environmental changes.
What is the theory of natural selection?Natural selection is the procedure via which populations of living organisms acclimate and modify.
Individuals in a population are naturally variable, indicating that they are all distinct in some manner. This divergence means that some individuals have characteristics better suited to the environment than others.
Natural selection leads to evolution.
Thus, genetic diversity best allow a species to survive environmental changes.

What is a hypertonic, hypotonic, and isotonic solution?
Answer:
Explanation:
If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, the relative concentrations of solute and water are equal on both sides of the membrane. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.

Name 2 differences between plant and animal cells.
A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. Animal cells simply have a cell membrane, but no cell wall.
Answer:
A difference between plant cells and animal cells is that most animal cells are round whereas most plant cells are rectangular
Plant cells have a rigid cell wall that surrounds the cell membrane

and why other cells undergo meiosis
Explanation:
Mitosis allows for cells to produce identical copies of themselves, which means the genetic material is duplicated from parent to daughter cells. Mitosis produces two daughter cells from one parent cell. Single-celled eukaryotes, such as amoeba and yeast, use mitosis to reproduce asexuallyand increase their population. Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. ... Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome.

Define 3 of the major parts of the skeletal system and list the
function(s) of each (bones, ligaments, and tendon, cartilage.)
Answer:
Bone
The major functions of the bones are body support, facilitation of movement, protection of internal organs, storage of minerals and fat, and hematopoiesis. Together, the muscular system and skeletal system are known as the musculoskeletal system.
Ligament
Ligaments connect the ends of bones together in order to form a joint. They also assist in holding organs in place. Tendon: A tough, flexible and inelastic band of fibrous connective tissue that connects muscles to bones.
Tendon
A tendon is a fibrous connective tissue which attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure.
Cartilage
Cartilage: This smooth and flexible substance covers the tips of your bones where they meet. It enables bones to move without friction (rubbing against each other). When cartilage wears away, as in arthritis, it can be painful and cause movement problems.

Fungus is an organism not drawn in the above food chain although it has a very important role. Describe an important role of organisms such as fungi and bacteria can you help me plz!!!
Answer:
Explanation:
Fungi and bacteria are decomposers. This means they help breakdown dead plant and animal matter.
This is kind of a baseline descripiton but i hope it helps!
Two of the most crucial creatures in an ecosystem are fungi and bacteria. They are essential for the nutrition cycle, the breakdown of organic matter, and the generation of food for other species. In order for other creatures to exploit the complex organic compounds, fungi and bacteria convert them into simpler forms.
What is the way to the food chain ?For instance, when dead plants and animals are broken down by fungi and bacteria, vital nutrients like nitrogen, phosphorous, and sulphur are released into the soil. Following the uptake of these nutrients by plants, food is produced that is then devoured by other species in the food chain.
Additionally, bacteria and fungi collaborate with other living things like plants in symbiotic interactions. For instance, several fungi collaborate with plant roots to provide the providing the plant with nutrients it needs in exchange for carbs.
Mycorrhizal symbiosis is the name for this kind of partnership, which is necessary for the development and well-being of plants. Since many bacteria and fungi produce chemicals that can stop the formation of dangerous infections, they also play a significant part in disease prevention.
Finally, fungus and bacteria are significant food sources for many organisms. For example, fungi like mushrooms and others feed animals like deer, birds, and other fauna.
