False

Answers

Answer:

The answer is true.. it is attached to the carbon backbone.

The statement "An unsaturated fat has the maximum number of hydrogens attached to the carbon backbone" is definitely true.

What is Unsaturated fat?

Unsaturated fat may be defined as a kind of fat carrying a high proportion of fatty acid molecules with at least one double bond. This type of fatty acid is considered to be healthier in the diet than saturated fat.

An unsaturated fat generally contains almost all of the hydrogen atoms which are directly attached to the carbon backbone in a series of systematic arrangements.

Unsaturated fat is typically fatty acid that remains liquid at room temperature and comes from a plant, such as olive, peanut, corn, cottonseed, etc.

Therefore, the statement "An unsaturated fat has the maximum number of hydrogens attached to the carbon backbone" is definitely true.

What is the division of type based on?

Answers

Answer:

There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life.

Explanation:

Is this a good problem/observation?

Answers

Yes, but maybe limit your experiment to a certain type of plant. Because you’re changing the type of plant and the frequency it may interfere. So maybe put only one specific type of plant- so maybe say something like “I want to observe whether my wild flowers grow faster depending on the frequency I water them- once a day in comparison to once every two days, or a week.”

Answers

Answer:

below

Explanation:

It's not necessarily that a large forest can only have a small population of wolves because a larger population will not affect the ecosystem that much but it just depends on the area. One forest may have more prey than others which the wolves rely to eat and stay healthy.  So yes it would be preferred to have a smaller population but again, it doesn't hurt to have a large one either. The main problem with having a larger population of wolves can be one of two issues;

Ways in which biology, technology, and society are connected?

Answers

Biology and technology are connected in many ways and virtually everything will eventually affect society in some way or another. The technological advances of biology are currently having a massive effect on society due to the length of people's lives increasing. It is now common for people to live well into their 80's and 90's which is mainly due to new medications and treatments that can prevent and cure disease and infection. Most of the elderly will have a concoction of medications it is necessary for them to take on a daily basis in order for them to live happy and fulfilling lives. 50 years ago this would not have been available and they would have died much younger.

Technology and biology
The Technological advancement towards a cure for cancer seems to be getting closer every day. More and more people are now surviving cancer which was previously such a massive killer in people of all ages. Immunization is now available for every single person in developed countries so diseases are less common. Sanitation is now much better so illnesses that were previously caused by ill health, dirt and germs are now much lower because we are not exposed to such things on a daily basis.

This is all fantastic news as it living longer is something that virtually everyone wants.

Advancements and society
We want to get the most out of our lives and live a long and fulfilling life. But many countries are now struggling to cope with the increase in elderly people who need help and support from the government in order to survive. Many elderly people need people to care for them or do not have enough money to live and no way of working to provide themselves with an income. Pension plans, hospital care and home nursing care must be provided for the people who cannot afford it themselves and this is a massive drain on the economy and has a knock on effect to society and effects us all.

A female has a brother who is color blind and a mother who is not.
What is the probability that the female is a carrier for the trait?

25%

100%

50%

0%

Answers

I’m pretty sure it’s a 50% chance since the colorblind mother has two kids and one of them has the trait.

25% is the probability that the female is a carrier for the trait. So, the correct option is (A).

What is Colourblindness?

Color blindness is defined as a reduced ability to differentiate between colors compared to the norm of normal human color vision. It is also called color vision deficiency (CVD) when a person is color blind, usually having difficulty distinguishing between certain colors such as yellow and orange, green and brown, pink and grey, or blue and green. Purple. These are typical of what is called "red-green color blindness".

The genes that can give red-green color blindness are passed on the X chromosome, although it is passed on the X chromosome, red-green color blindness is more common in males, causing males to inherit it from their mothers. There is only 1 X chromosome.

In the above case, if the mother is not colour blind but her son is color blind so, the probability for her daughter is 25%.

Thus, 25% is the probability that the female is a carrier for the trait. So, the correct option is (A).
