Most mutations that cause cancer occur within body cells, and body cell mutations are not inherited. If cancer is not inherited, why does cancer statically appear to run in families?

Answers

Answer 1

Answer: The cause of acquiring cancer does not only rely on genetics. Cancer can be caused by a lot of factors and the most common factor considered why it statistically appear to run in families is the family's lifestyle. Most forms of cancer are lifestyle-related, and can be prevented. For example, Colon cancer. Usually a person is at risk to acquire colon cancer when he/she consumes too much processed meats and meats that are cooked at a very high temperature, alcohol use and overeating. Usually this kind of eating lifestyle is shared by the family.

How do the products and reactants of a chemical change compare?The mass of the products is greater than the mass of the reactants because energy is taken in by the reaction. The mass of the products equals the mass of the reactants because the same matter is present. The mass of the products equals the mass of the reactants because there is no energy involved in the reaction. The mass of the products is less than the mass of the reactants because energy is given off by the reaction.

Answers

Q1. The answer is b. cones.
Reproductive structures of gymnosperms are cones while reproductive structures of angiosperms are flowers. The gametophytes are found in reproductive structures which are called cones in gymnosperms.

Q2. The answer is d. ovules.
The female gametophyte of gymnosperms develops inside the ovules borne on the surface of ovuliferous scale of an ovulate cone while the female gametophyte of angiosperms develops inside the ovules located inside the gynoecium of the flower.

Q3. The answer is a. pollen grains.
Nevermind if a gymnosperm or an angiosperm, pollen grains are always haploid structures so when they fuse with haploid female gamete, a diploid zygote is formed.

why might it be beneficial to regulate what species of plats and animals people are allowed to own in particular environments

Answers

Hi there!

Regulating species and plants in a certain area is beneficial for a lot of reasons. Below I'll list one of the most important reasons for regulating.

- Invasive species. As a direct result of the danger invasive species pose, regulating animals and plants in an area can help reduce the risk of a non-native species wrecking havoc on the environment. In the past and as of today many pet owners buy plants and animals from across the globe. Once they get too big some release them into the environment without any regards for the potential disaster it could bring. An example of this would be the Burmese Python which completely upset the ecosystem of souther Florida once let loose.
