Answer:
Cancer is a disease that has abnormal cells, that begin to divide that then becomes uncontrollable and destroy the body tissue. When cancers has "metastasized" is when it spreads from one part of the body to another part of the body.
Explanation:
As an example, when cancer starts in the lung and then metastasized to the chest or to the rest of the body.
If an organisms has 50 chromosomes in a diploid
cell, how many would be in a haploid cell?
Answer
25
Explanat
Bcz the total number of chromosome are divided into two
Animal and plant cells have thread-like fabrications in their nucleus made up of DNA and proteins. It is the most important for passing the genetic information from the parent to the offspring.
If the organism has 50 chromosomes in a diploid cell, it will have 25 chromosomes in a haploid cell.
This can be explained as:
Diploid is a cell condition in which the chromosomes are found in pairs and is represented as 2n. They have one set of chromosomes from each parent.Haploid (n) is a cell condition when there is only half the number of chromosomes present or when there are only chromosomes from the single parent.Therefore, in the haploid condition 25 chromosomes will be present.

Which of the following best describes the hydrolysis of carbohydrates
Answer:
The addition of a water molecule breaks a covalent bond between sugar monomers
Explanation:
The digestion of carbohydrates by enzymes is an example of a hydrolysis reaction.
Carbohydrates are chains of monosaccharides. Hydrolysis involves the addition of a water molecule that cleaves the covalent bond between the molecules of sugar.
The reverse reaction is a condensation reaction, the joining of sugar monomers to create a carbohydrate releases a molecule of water.

Bone marrow is a spongy tissue found inside bones.
Red bone marrow involves the production of blood cells. Yellow bone marrow produces cartilage and is important for fat storage.
Which of the following correctly describes the function of the cell wall?
The cell wall provides rigid support and protection for the cell.
The cell wall is a network of fibers inside the cell that gives the cell its shape.
The cell wall is a barrier that allows certain substances into and out of the cell.
The cell wall is a series of folded membranes that produces and distributes proteins in the cell.
The cell wall is a layer outside the cell membrane and provides rigid support and protection to the cell. So, the correct option is A.
What is a cell wall?A cell wall is a thick and rigid layer composed mainly of polysaccharides present outside of the cell membrane that protects the cell. A cell wall is a part of a cell but it is not a living component. Unlike the cell membrane, a cell wall is totally permeable in nature.
The cell wall of different kinds is present in plants, fungi and prokaryotes. Animal cells do not have a cell wall.
The cell wall in fungi is made up of a polysaccharide called chitin. This component is also present in the exoskeletons of arthropods.
The cell wall in the case of prokaryotes is made of a polysaccharide called peptidoglycan. Prokaryotes have 2 layers in their cell wall.
Plants contain cell walls made of cellulose. The plant cell wall has 3 layers. These are pectin, cellulose and hemicellulose. It also contains a small number of minerals.
The materials required for the formation of the cell wall are a special kind of polysaccharide called structural polysaccharides. The monomer for these polysaccharides is glucose.
Therefore, the correct option is A.

Write a paragraph in the space below, explaining in your own words how electromagnetic radiation is created by the Sun. Describe the difference between the different forms of electromagnetic radiation and how scientists classify the types of electromagnetic radiation.
Answer:
The electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to frequency and wavelength. The sun, earth, and other bodies radiate electromagnetic energy of varying wavelengths. Electromagnetic energy passes through space at the speed of light in the form of sinusoidal waves.

What is the Connective tissue?
What is the Epithelial tissue?
What is the Muscle tissue?
What is the Nervous tissue?
Answer:
connective: Tissue that supports, protects, and gives structure to other tissues and organs in the body
epithelial: are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands.
muscle: Muscle tissue is composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts. The tissue is highly cellular and is well supplied with blood vessels.
nervous: Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities.
Explanation:
Answer
Connective tissues gives support, protects and gives structure to other tissues and organs in the body.... example bone, cartilage, blood etc.
Epithelial tissues are spread throughout the body. Their functions include secretion (sweat, mucus), absorption (nutrients) and protection (tissues that lie beneath from radiation) in the body.
Muscle tissue is composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts.
Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities.

Which of the following are sources of low-level radiation?
A)
medical X-rays
B)
nuclear weapons testing
C)
buring of fossil fuels
D)
all of the above
E)
a and c only
Answer:
im pretty sure its E
Explanation:
The sources of low-level radiation are A) medical X-rays and E) the burning of fossil fuels, so the correct answer is E) a and c only, as radiation can be classified into two main types: ionizing radiation and non-ionizing radiation.
What is radiation?Medical X-rays are a type of ionizing radiation used for medical imaging. Although the amount of radiation exposure from a single X-ray is usually very small, frequent exposure to X-rays can increase the risk of cancer. The use of X-rays in medical imaging is carefully monitored to ensure that the benefits outweigh the risks. Ionizing radiation has enough energy to remove tightly bound electrons from atoms, which can cause damage to living tissue and increase the risk of cancer. Medical X-rays and the burning of fossil fuels are sources of ionizing radiation that can produce low-level radiation.
Hence, the sources of low-level radiation are A) medical X-rays and E) the burning of fossil fuels, so the correct answer is E) a and c only.

Answer:
a
Explanation:
because it is beneficial in both plant an water
Answer:
(B) No this would not be a symbiotic relationship.
Explanation:
this is because symbiotic relationship is where the two organisms have a mutual relationship where they depend on each other. The plants depend on water for their growth while the water does not depend on anything from the plants.
An example of a symbiotic relationship is between rhizobium bacteria and leguminous plants.The rhizobium bacteria gets shelter and food from the leguminous plants while the leguminous plants use the bacteria to convert nitrogen in the air to nitrates through a process called nitrogen fixation.

Describe the difference between the different forms of electromagnetic
radiation and how scientists classify the types of electromagnetic radiation.
Answer: Light is a form of electromagnetic radiation. Other forms of electromagnetic radiation include radio waves, microwaves, infrared radiation, ultraviolet rays, X-rays, and gamma rays. The only difference between them is their wavelength, which is directly related to the amount of energy the waves carry. Scientists classify them by the frequency of their wavelength, going from high to low frequency. When a wave has a lot of energy, it could be a gamma ray or x-ray. If it has low frequency, it has less energy and could be a TV or radio wave.

A plant is the most balanced need for water within its need for carbon dioxide and oxygen. It’s too much water is lost, the stomata will close. How does this affect the plants ability to regulate levels of carbon dioxide and oxygen?
Answer:
it helps regulate them and keep them level going through the state of transpiration
Explanation:
to prevent too much water lost a plant will close it's stoma to store that water, this process is called transpriation. if the stoma is open it will dry out the plant.
so a plant losing water in reaction they will close their stoma which is homeostasis, homeostasis is balance. so for example u go through homeostasis when it's hot outside it results in u sweating, why? cause your body is trying to cool down and regulate it's self.
