A mutation to the p53 gene can cause what type of disease?
-Cancer since the delay in the cell cycle is disrupted.
-Nondisjunction causing an abnormal number of chromosomes.
-Cystic fibrosis due to a mutation in the gene that codes for a specific protein.
-Sickle cell causing abnormally shaped red blood cells.
Answer: A mutation to the p53 gene can cuase cancer since the delay in the cell cycle is disrupted.
A mutation to the p53 gene can cause this type of disease: Cancer since the delay in the cell cycle is disrupted.
A cell cycle is as an ordered sequence of events that takes place within a living cell as it grows and divide into two new daughter cells.
Cancer can be defined as the uncontrolled division of certain body cells, which then invade the surrounding tissues and interfere with the normal functioning of the body.
Some examples of cancer are:
Breast cancer.Prostrate cancer.Carcinoma.A tumor can be defined as an abnormal mass of tissue formed when various body cells grow and divide more than its required or fail to when necessary (required).
Thus, it usually degenerate into cancerous growths (cancer).
In conclusion, it is caused by exposure to extremely dangerous radioactive substances such as gamma ray, uranium etc.

The term science comes from the Latin word "scientia" which means knowledge. But this statement is too broad in its everyday use. In a narrow sense, science is a discipline consisting of physical sciences (physic) and life sciences (biological sciences).
What are some key chemical reactions that occur in your body?
The sum of all of the biochemical reactions in an organism is called metabolism. Metabolism includes catabolic reactions, which are energy-releasing (exothermic) reactions, as well as anabolic reactions, which are energy-absorbing (endothermic) reactions.
Answer:
metabolism is a chemical reaction in the body's cell the change food in to energy (answer would be Metabolism)

Two particles, a neutron and an electron, are to be added to this model.
In what location should each be added?
Answer:
Electrons are part of the atom, but are "orbiting" around the nucleus, which is composed of the protons and neutrons. The protons determine the elemental properties (valence states) and the neutrons determine the isotope and total mass (with the protons)
Explanation:
Electrons are part of the atom, but are "orbiting" around the nucleus, which is composed of the protons and neutrons. The protons determine the elemental properties (valence states) and the neutrons determine the isotope and total mass (with the protons)
The particles of neutrons are to be added to the nucleus of the element, while the particles of electrons are added to the orbiting shells that surround the nucleus.
What are Neutrons and electons?Neutrons and electrons may be defined as subatomic particles having different charges and masses. The particles of electrons are negatively charged while the particles of protons are neutral i.e. bearing no charge.
Electrons are always revolving around the orbiting shells around the nucleus. The nucleus of the element is composed of protons and neutrons. The neutrons specify the atomic mass as well as isotopes of numerous elements.
Therefore, the particles are always added to the position where they actually belong to. Similarly, the particles of neutrons are to be added to the nucleus of the element, and the particles of electrons are added to the orbiting shells.

Which type of carbohydrate is this?
A) Monosaccharide
B) Simple sugar
C) Complex carbohydrate
D) Disaccharide
Answer:
A
Explanation:
monosaccharide is derived from mono, meaning "one", and saccharide, meaning "sugar". The common monosaccharides are glucose, fructose, and galactose. Each simple sugar has a cyclic structure and is composed of carbon, hydrogen and oxygen in ratios of 1:2:1 respectively. Although each sugar mainly exists as a cyclic compound, it is important to note that they are all in equilibrium to a small extent with their linear forms.
While galactose and glucose are composed of six-membered rings, fructose has only five carbon atoms bonded to each other in ring form.

how do geologists fill gaps in the rock record?
Answer:
Through assumptions
Explanation:
The cell walls of a plant consist mostly of cellulose, a carbohydrate, which provides a strong structure. The cell membrane gets its structure primarily from lipids, and embedded proteins allow for material transport.
Answer:
Common to all plant species, the cell wall is the tough outer coat that protects the plant cell. The cell wall is mostly carbohydrate‐based, comprising three major classes of polysaccharides: cellulose, hemicellulose and pectin. There are also important structural proteins as well as phenolic and aliphatic polymers.

differentiate between Angiosperms and gymnosperm
Answer:
Angiosperms are vascular plants bearing the seeds in fruits or mature ovaries whilst gymnosperms are other types of the plant which bears the seeds directly on the sporophylls but without any cover.
Explanation:
Examples of gymnosperms include cypress,pine, redwood, spruce and ginkgo.
Examples of angiosperms include apple, banana,peach, cherry and orange.
Also, angiosperms are seeds producing flowering plants whose seeds are enclosed within an ovary.
Gymnosperms are also seeds producing non flowering plants whose seeds are unenclosed.

According to appearances, which light produces the healthiest plant?
Green
Blue
Yellow
Red
Answer:
Blue light
Adding 10-20% blue light allowed plants to grow much healthier, with a compact appearance. There is also far-red light which is has wavelengths that are lower than normal red light–similar to near-infrared wavelengths. Far-red light helps the plants produce greater yields.

An object weighs 40kg on Earth. Describe how the weight of an object would change if it were put on the moon.
The weight would decrease because there is less gravity on the moon.
The weight would increase a little because of more gravity on the moon.
The weight would not change because the amount of matter is the same.
The weight would change because the amount of matter changes with gravity.
