What are the two main factors that cause individuals of the same species to appear different?
Genetic variation and environmental factors are the two main factors that cause individuals of the same species to appear different. Genetic variation results from differences in DNA sequences passed down through generations, while environmental factors such as diet, climate, and exposure to sunlight can also influence physical appearance.
What two types of chromosomal mutations?
Two are insertion mutations and deletion mutations.
What are two environmental factors that can cause a seed to end dormancy and germenate?
Two environmental factors that can cause a seed to break dormancy and germinate are sufficient water availability and appropriate temperature. Adequate moisture helps soften the seed coat, allowing the embryo to swell and begin growth, while suitable temperatures trigger biochemical processes necessary for germination to occur.
What is the most likely reason for a mutation to occur?
Several in cause. It could be as simple as a copying error during replication, a thymine dimer in a skin cell's DNA due to UV light, or a carcinogenic mutation of a cell's DNA as a precursor to cancer.
Anyone in your class has all the same genetic traits that you have?
No, it is highly unlikely that anyone in my class has all the exact same genetic traits as me. Genetic traits are influenced by a combination of factors including parental inheritance, mutations, and environmental influences, making it rare for two individuals to share identical genetic traits.
What are two possible environmental factors that can cause cancer?
Exposure to carcinogens, such as tobacco smoke or ultraviolet radiation, can increase the risk of developing cancer by damaging DNA. Additionally, environmental pollutants like asbestos or radon can also contribute to the development of cancer by causing genetic mutations in cells.

Name two things that can cause cancer?
Cancer is a complex group of diseases, and its causes are often multifactorial. However, two significant factors that can contribute to the development of cancer are: Genetic Factors: Inherited genetic mutations can increase the risk of certain types of cancer. These mutations can be passed down from parents to children and may predispose individuals to a higher likelihood of developing specific cancers. Environmental Factors: Exposure to certain environmental factors can contribute to the development of cancer. This includes exposure to carcinogens, which are substances or agents that can promote the formation of cancer. Carcinogens can be found in pollutants, tobacco smoke, certain chemicals, radiation, and some infectious agents.
What is known to cause autism?
"The cause it not yet known. It seems that no two autistic children are alike. According to the Mayo Clinic, there are many likely causes such as genetic disorders and environmental factors."
What two types of chromosomal mutations?
Two are insertion mutations and deletion mutations.
What determines the outcome of a mutation?
There are plenty of factors that can induce mutations. There are several harmful rays, such as X-rays and gamma rays, that can affect the DNA structure within gametes and that can cause mutations to occur. There are certain types of food that can also have the same affect. There are also genetic factors that can cause mutations. During Anaphase two where the DNA materials are splitting apart to form gametes, a process known as non-disjunction can occur where one of the gametes has an extra set of chromosome and the other has one or more less set of chromosomes.
What are the two groups of environmental factors that influence organisms?
dioxide and nitrogen
What are the factors that cause evolution to occur?
The two main factors are mutation and natural selection.Mutations are random changes in our DNA that cause changes. Some of these changes are bad, some are neutral, and some are good.This is where natural selection comes in. If the mutation is bad, then that organism is less likely to mate and pass down the gene. The organism dies along with the mutation that made it less fit. If it is neutral, which is what most mutations are, then nothing happens. If it is good, then the organism is more likely to survive and pass down the gene which will then propagate through the species.
What two things can cause a population to decrease?
A low birth rate and environmental hazards are two things that can cause a population to decrease.

What two things that cause cancer?
Cancer is a complex and multifactorial disease, and it typically results from a combination of genetic, environmental, and lifestyle factors. Identifying specific causes for cancer is challenging due to the diversity of cancer types and individual variations. However, two broad categories of factors associated with an increased risk of cancer are: Genetic Factors: Inherited Mutations: Certain genetic mutations can increase the likelihood of developing cancer. These mutations can be inherited from parents or arise spontaneously. Family History: Having close relatives with a history of certain cancers may indicate a genetic predisposition. Environmental and Lifestyle Factors: Tobacco Use: Smoking and tobacco use are major causes of various cancers, including lung, throat, mouth, and bladder cancer. Diet and Physical Activity: Poor dietary habits, lack of physical activity, and obesity have been linked to an increased risk of certain cancers. Exposure to Carcinogens: Occupational exposure to certain chemicals and substances, as well as environmental exposures to pollutants and radiation, may contribute to cancer risk. Infections: Some infections, such as human papillomavirus (HPV), hepatitis B and C, and Helicobacter pylori, are associated with an elevated risk of specific cancers. Sun Exposure: Prolonged exposure to ultraviolet (UV) radiation from the sun or artificial sources is a known risk factor for skin cancer.
What are all the environmental factors causing corrosion?
Corrosion, as in the corrosion of iron into rust, needs two environmental factors: 1. oxygen present in the atmosphere 2. water/moisture present in the the atmosphere
