How do polar bear adapt to its environment?
Answer:
Polar bears have thick fur coats that help keep them keep warm in cold conditions. They have a dense layer of fur close to the skin and an outer layer of longer fur. The inner layer isulates them against the cold. ... The skin underneath their fur is black and absorbs the heat from sunlight, helping them stay warm.
Explanation:
The way polar bears adapt to their environment is because of their thick warm coat.
Which would best allow a species to survive environmental changes? (8.L.4.2)
similar physical
features
low mutation rate
genetic diversity
small population
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.

Which is observation proves that a cell is a eukaryote?
A.it has DNA in the cell
B.it has ribosomes inside the cell
C.it has enclosed organelles inside the cell
D.it is surrounded by a cell membrane
Answer:
The answer is C
Explanation:
Only eukaryotic cells have membrane-bound organelles, so that would be proof that the cell is a eukaryote.
which statement correctly describes the relationship between genes, proteins, and traits?
Answer:
C. Genes are transcribed into mRNA, the mRNA is then translated into proteins, which determines specific traits.
Explanation:
Genes are segments of the genetic material (DNA) that encodes certain products, which are heritable. In the central dogma of biology, genes are expressed via two processes viz: transcription and translation.
Transcription is the process whereby the information in genes are used to synthesize mRNA molecule, while Translation is the process whereby the mRNA molecule is used to synthesize proteins in the ribosome.
The proteins are responsible for the individual characteristics or traits possessed by living organisms. For example, MELANIN GENE is transcribed into MELANIN mRNA, which is then translated into MELANIN PROTEIN responsible for the skin colour (trait).

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.

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.
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
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.

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).
Which statement forms part of cell theory?

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.
A wet mount of unstained Elodea ( a green aquatic plant) is observed using high power (400x) of a compound light microscope. Which structures would most likely be observed? ribosome, Golgi complex, and vacuole ribosome, Golgi complex, and vacuole nucleus, chloroplast, and cell wall nucleus, chloroplast, and cell wall centrosome, lysosome, and plasma membrane centrosome, lysosome, and plasma membrane cytoplasm, endoplasmic reticulum, and nucleolus
Answer:
The correct option is "nucleus, chloroplast, and cell wall"
Explanation:
The specimen described in the question is said to be green aquatic plant. Hence, the organelles expected to be viewed are those present in a pant cell.
Although, nucleus (stores the genetic material) is present in both plant and animal cells, however, chloroplast (to provide the green colour for the aquatic plant) and cell wall (for the cell's rigidity and support) are only found in a plant cells.
