What is an organ ?

An organ within an organism performs specific tasks to maintain the overall health and function of the organism. To accomplish these tasks, an organ typically requires interaction with other organ systems within the organism.

For example, the digestive system works in tandem with the circulatory system to transport nutrients to the cells, while the respiratory system works with the circulatory system to deliver oxygen to the body. By working together, the different organ systems help to maintain the overall health and function of the organism.

Option (B) the human eye is only sensitive to a portion of the electromagnetic spectrum (visible lights) best supports above statement.

What are electromagnetic waves?

Electromagnetic radiation is made up of electromagnetic field waves that travel through space carrying electromagnetic radiant energy. These waves are carried by electromagnetic radiation. Radio waves, microwaves, infrared, light, ultraviolet, X-rays, and gamma rays are all components of this spectrum. The electromagnetic spectrum is made up of all of these different types of waves.

We can only see a small portion of the electromagnetic radiation that exists, which is the portion that we refer to as visible light. However, all electromagnetic radiation is light. These cone-shaped cells in our eyes function as receivers and are tuned to the wavelengths that are present in this particular narrow band of the electromagnetic spectrum.

B. The arctic fox is a producer while the pine tree is a consumer
C. The pine tree is abiotic while the arctic fox is biotic.
D. The pine tree is not adapted to survive in the cold weather

Please help!

Answer:

Explanation:

The fox's cells do not have a cell wall, since it is an animal, while the tree does, since it's a plant. B is not correct since they have reversed roles, C is not correct since both are biotic, and D is not correct since both are adapted to cold weather. Hope this helps!

One main difference between a pine tree and an arctic fox is the cells of the pine tree have a cell wall, and the cells of the arctic fox do not.

A plant cell is defferent from the animal cell due to presence of cell wall an large vacuole while the animal cell surrounded by the cell membrane only.

Since, arctic fox is an animal and pine tree is a plant, both the organism found in the cold wether.

Describe a DNA mutation and how it can affect an offspring.

Answers

A DNA mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes. DNA mutations can affect an offspring can result in abnormal protein products. Mutations can also introduce new alleles into a population of organisms and increase the population's genetic variation.

Since all cells in our body contain DNA, there are lots of places for mutations to occur; however, some mutations cannot be passed on to offspring and do not matter for evolution. Somatic mutations occur in non-reproductive cells and won't be passed onto offspring. For example, the golden color on half of this Red Delicious apple was caused by a somatic mutation. Its seeds will not carry the mutation.
The only mutations that matter to large-scale evolution are those that can be passed on to offspring. These occur in reproductive cells like eggs and sperm and are called germ line mutations.

Calcium has a number of 20 protons, electrons, and neutrons. Since it looks like the atoms has a charge to it so it has not gained or lost electrons the number of electrons hasn’t changed. Also the atomic number of the element (or the number 20) determines how many protons, neutrons, and electrons in an element without a charge.

Calcium has a number of 20 protons, electrons, and neutrons.

What are the functions of calcium?

Calcium is a mineral most often associated with healthy bones and teeth, although it also plays an important role in blood clotting, helping muscles to contract, and regulating normal heart rhythms and nerve functions.

Calcium is essential for building and maintaining healthy bones and teeth. Among other roles, it may also help manage blood pressure. It is best to obtain sufficient calcium through dietary sources.

Answer:

Genes play an important role in determining physical traits — how we look —and lots of other stuff about us. They carry information that makes you who you are and what you look like: curly or straight hair, long or short legs, even how you might smile or laugh. Many of these things are passed from one generation to the next in a family by genes. Most cells have one nucleus. The nucleus is a small egg-shaped structure inside the cell which acts like the brain of the cell. It tells every part of the cell what to do. It contains our chromosomes and genes. Chromosomes come in matching sets of pairs and there are hundreds (sometimes thousands) of genes in just one chromosome. The chromosomes and genes are made of DNA.

According to the map, which body of water was controlled by the Roman Empire?

the Red Sea
the Black Sea
the Caspian Sea
the Persian Gulf

Answers

It is the black sea. Correct answer is the Mediterranean but it’s not one of your choices so Black.

The Mediterranean Sea was controlled by the Roman Empire which was not given in the options.

What is the Mediterranean Sea?

The Mediterranean Sea is a sea connected to the Atlantic Ocean that is encircled by the Mediterranean Basin and nearly entirely surrounded by land on the north, Western and Southern Europe and Anatolia, on the south, North Africa, and on the east, the Levant.

In the history of Western civilization, the sea has played a crucial role. Although the Mediterranean is often included in the Atlantic Ocean, it is widely regarded a separate body of water.

According to geological data, the Mediterranean was shut off from the Atlantic approximately 5.9 million years ago and was partially or fully dry for 600,000 years during the Messinian salinity crisis until being flooded by the Zanclean flood about 5.3 million years ago.

The Roman empire was based on the unification of the Mediterranean Sea.

The Romans, who lived in a little town on the Italian peninsula in the Mediterranean's western basin, had conquered the western basin first, and later the eastern basin of this nearly land-locked body of water.

Hence , the correct answer is The Mediterranean Sea.
