Which of the following statements about the relationship between genetic and environmental factors relating to health is true?
a. No health issues arise without an interaction between genetic and environmental factors.
b. Health issues related to toxic environments can occur independent of genetic inheritance.
c. Health issues, such as depression, are related solely to environmental factors.
d. There is no known connection between environmental factors and health.
Answer:
Health issues related to toxic environments can occur independent of genetic inheritance.
Explanation:
The statement which is true about the relationship between genetic and environmental factors relating to health is, that health issues related to toxic environments can occur independently of genetic inheritance.
What do you mean by Genetic inheritance?Genetic inheritance may be defined as a principle that explains the process of characteristics that are passed from one generation to the next.
The toxic environment is responsible for the number of health diseases among organisms. These diseases may reflect the pattern of genetic inheritance as well, but it is not significantly accepted or analyzed.
Genetic inheritance depends on the physiological characteristics of involving parents.
Therefore, the statement which is true about the relationship between genetic and environmental factors relating to health is, that health issues related to toxic environments can occur independently of genetic inheritance.

Why does evolutionary theory absolutely require the earth to be very
old?
Answer:
Because it takes time for the animals to adapt to their environment, and change their DNA
Answer:
Because evolutions don't happen overnight, it takes years and years for an organism to develop an evolution. So, the earth has to be old, because if we look at the earth when it was young, then we don't really see any evolutions. However, if we look at it when it's old, we can see that there were many evolutions. I hope this helps!

In order to maintain homeostasis, it is MOST important for an animal to be able to?
Answer:
Homeostasis is the way animals maintain a stable internal balance in their body. It allows animals to function in the changing external conditions surrounding their body. Homeostasis is important to Chinook salmon because they depend on the functioning of its cells to help its survival and ability to reproduce.
Explanation:
In order to maintain homeostasis, the animal should be able to respond to environmental conditions.
What is homeostasis?The word homeostasis can be defined as the presence of a state of equilibrium in a given biological system.
Homeostasis is fundamental for surviving in challenging environmental conditions.In conclusion, in order to maintain homeostasis, the animal should be able to respond to environmental conditions.

Where does the H+ come from that makes ATP synthase work?
Answer:
Electron Transport Chain
Explanation:
Gizmos Cell Respiration
The H+ that's vital in making ATP synthase work comes from the electron transport chain.
The electron transport chain can be found in the mitochondria. It is a series of protein complexes that are able to transfer electrons from the electron donors to the electron acceptors.
It should be noted that the transfer of the electrons from the electron donors to the electron acceptors is done through the redox reactions. This is illustrated in the H+ that made the ATP synthase work.

Answer:
Bacteria are single-celled organisms but most fungi are not.
Explanation:
Bacteria are single-celled microscopic organisms that are characterized by the presence of incipient nucleus and few membrane-less cell organelles. Fungi, singular fungus, are eukaryotes that are characterized by the presence of chitin in the cell wall. All bacteria are prokaryotes. All fungi are eukaryotes
Answer:

How many electrons must get passed down the Electron Transport Chain before energy is generated?
Answer:
4 electrons
Explanation:
Electron transport chain is defined as the series of process in which electron transfer takes place across a membrane. It is consists of enzymes, peptides, and other molecules.
There are 4 electrons that passed down the Electron Transport Chain before energy is generated. These Four electrons further reduce each molecule of oxygen. Oxygen binds with free proton and form water and move across the membrane to form ATP.
Hence, the correct answer is "4 electrons".

An organism was found. It is unicellular, but its one cell does contain a nucleus and the cell is autotrophic. What type of organism is this?
A
animalia
B
protista
C
bacteria
D
fungi
Answer:
B protista
Explanation:
The cell is unicellular, so it can not be an animal, which are all multicellular.
It contains a nucleus, which means it cannot be prokaryotic (it cannot be bacteria)
The cell is autotrophic, which means it cannot be a fungus, which are heterotrophs
Therefore, the organism must be a protist, so the answer is B, protista.

how are proteins made in animals and humans
Answer:
Through protein synthesis of course...
Explanation:
DNA and RNA do many steps such as translation, transcription, and more to form protein codons and code them into amino acids. Then, thousands of amino acids are oined together to make proteins, which regulate body function and catalyze chemical reactions (enzymes). Ribosomes are also involved in this action. To make proteins, nitrogen is needed for the plant to use, and that comes mainly from nitrate ions in the soil, and gets into the plant by active transport.
Do you have more cells now than you did when you were five?
Answer:
No After your cell dies of another one come. Your cells are still the same
Explanation:
When you age, cells do divide and reproduce more cells. However when you age the reproduction process of cells gets slower and they can die off before they can reproduce. There can be many problems with your cells that can make cell count lower such as Atrophy, and Dysplasia. When you age, cells are a contributing factor of making you age. They can change your skin, face, etc.. So the answer would be no, you would not have more than you did when you were five.
