Which of the following statements is best demonstrated by the model?

Answer:

Some animals have adapted to life in the taiga by hibernating when temperatures drop. Other animals have adapted to the extreme cold temperatures by producing a layer of insulating feathers or fur to protect them from the cold. In some instances, the adaptation of a seasonal change in color of feathers or fur protects the animal from its predators.

Explanation:

Answer:

- Accuracy is the degree by which the measures obtained in an experiment and/or observational procedure are associated with true values.

- Precision is the level of reproducibility that these measurements exhibit in the same (constant) conditions.

- Reproducibility indicates the level of agreement of the results when they are obtained by different researchers by applying the same experimental and/or observational procedures.

Explanation:

In a scientific investigation, it is imperative to achieve higher levels of accuracy and precision when realizing measurements because it ensures that the information is correct (without mistakes). Thus, researchers always try to use better equipment and instrument to make their measurements. Reproducibility is important because it is the only condition that scientists can guarantee to other researchers when they arrive at a result.

Explanation:

I believe the most useful ap to use for people of age is Faceb00k. Faceb00k is a safe and friendly app where people can share what there doing or pictures.

So many parents and grandparents use this today to share photos of younger family members, and others can like and comment on there posts. Although their are some who receive hate, most of the people are quite rather friendly.

People like to share there appreciation for l0ved ones by letting the whole world see them through Faceb00k. Most elderly people do this so there younger ones can look back at all the memories they had together. Yes, its true they can just not post it and still look back at memories, but they post it because if it gets deleted and you posted the photos online there will always be a way to recover them.

In conclusion, this is why I believe Faceb00k is the best ap for the more elderly people. Firstly, they can show there memories to the world by showing appreciation. And lastly, whenever you post something online it can always be recovered, so those valuable moments will not be forever lost.

Answer:

The Wave Equation

Multiplying the wave's frequency by its wavelength, which is its physical length, yields the velocity of the wave.

Explanation:

Answer:

Just v = f × λ

v is the wavespeed in m/s, f is the frequency (Hz) and λ is the wavelength (m)

Explanation:

A prokaryotic cell is a type of cell that does not have a true nucleus or membrane-bound organelles. Organisms within the domains Bacteria and Archaea are based on the prokaryotic cell, while all other forms of life are eukaryotic

A prokaryotic is a primitive cell that lacks organelles, unlike the eukaryotic cells, and are simple organisms.

Prokaryotes are organisms that are simple and evolved before the complex eukaryote. They include bacteria and archaea that are simple and lack organelles that are found in eukaryotes.

They do not have a nucleus and rather have their genetic material disposed of as nucleoids in the center of the cell that undergoes the simple process of the central dogma.

The simple cellular processes and reproductive methods are the reason they lack many organelles. This tells that prokaryotes are simple and primitive types of cells.

Therefore, prokaryotes lack a distinct nucleus.

C)the tails of plant lipids cannot pack as tightly together as animal ones

Explanation:

The tails of plant lipids cannot pack as tightly together as animal ones because the double bond in plant lipids make the hydrocarbon chains to bend making them no to pack tightly together which cause a reduction in van der Waals interaction between the fatty acids. The length of the double bond also affect the melting point of fatty acids . If the hydrocarbon chain is long, melting point will be high .

Explanation:

Answer:Stars are formed in clouds of gas and dust, known as nebulae. Nuclear reactions at the centre (or core) of stars provides enough energy to make them shine brightly for many years. The exact lifetime of a star depends very much on its size.

A star can be defined as a giant celestial (astronomical) object that is made up of a luminous sphere of plasma bounded together by its own gravitational force.

Generally, a star consists of two (2) main interstellar hot gas and these are:  

I. Hydrogen (H).

II. Helium (He).

Some of the examples of a star are;  

A nebula simply refers to a low-density cloud of interstellar hot gas (hydrogen and helium) and dust.

Basically, a nebula is needed for the creation or formation of a star.

Hence, the role of a nebula in the life cycle of a star include the following:

Stage 1: The temperature increases in the center of a nebula, thereby, causing the small nuclei of atoms to fuse.

Stage 2: The nebula gets hotter and brighter as the nuclear fusion sets off a chain reaction while providing enough energy to turn the nebula into a star.

Explanation:

Glucose is the end result of the calvin cycle. It is not Oxygen, NADPH, or ATP because those are produced in the light reactions.

Is glucose being produced? is the question which will best determine

whether a plant is undergoing the Calvin cycle.

The Calvin cycle is known s the light independent or dark reaction which

takes place during the process of photosynthesis by plants. The final

product for this cycle is Glucose.

Other compounds such as NADPH, ATP and oxygen are all formed during

the light dependent reactions which is why asking if glucose is produced is

the most appropriate choice.

The cellulose cell wall in plants

Explanation:

All eukaryotic cells, both plant and animals cells have a cell membrane which is an outer covering of the contents of the cell. Also plants and animals cells have many structures and cell organelles in common such as the mitochondria, the endoplasmic reticulum, ribosomes, golgi bodies, etc. However, plant cells have a more rigid structure than animals cells because of the presence of an extra structure known as the cell wall, covering their cell membranes.

The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection. The cell wall is composed mainly of cellulose, but contains proteins as well as other polysaccharides too.

Another structure present in plants that serves to maintain the rigidity of the plant cell is the large central vacuole. The main role of the vacuole is to maintain turgor pressure by pushing the plasma membrane against the cell wall due to the pressure of fluids contained within it.

Answer:

Sickle cell anemia is an inherited condition in which there aren't enough healthy red blood cells to carry oxygen through an individual's body. The red blood cells of a healthy individual are flexible and round, and they move through blood vessels with no problem, transporting oxygen successfully. However, a person with sickle cell anemia has rigid, sticky red blood shaped like sickles or crescent moons. These cells often get stuck in small blood vessels, which can slow or block blood flow and oxygen delivery to different parts of the body.

The sickle cell anemia trait is found on a recessive allele of the hemoglobin gene, while the regular red blood cell trait is found on the dominant allele. This means that a person must have two copies of the recessive allele (one from their mother and the other from their father) to be born with this condition. People who have one dominant and one recessive allele or both dominant alleles will have healthy red blood cells.
