What are the two bands of latitude on Earth that receive no light at times called?

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.

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.

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.

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.

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.

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.

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).

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.

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.

Edoplasmic reticulum

Explanation:

it's a network of membranes that folds, modifies, and transports proteins throughout the cell.

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.

Answer:

No

Explanation:

Cells and Atoms both have a nucleus, even though they are made of different things. They make up the main structure of the cell or atom. The weakness is that is all they have in common

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

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
