Which best explains the genetic similarities between species? A. More closely related species will have identical dna B. More closely related species will have fewer dna similarities C. More closely related species will have more similarities in dna D. There is no link between the relationships of species and their dna
Answer:
C
Explanation:
The correct answer would be that more closely related species will have more similarities in DNA.
The DNA stores the genetic information of organisms and contains a set of instructions that defines how organisms look. It is usually used to delimit species with closely related species of organisms having similar DNA. The more related species are, the more similar their DNA would be and vice versa because the similarity in the DNA of organisms is often used as an indication of descending from a common ancestor.
The correct option is, therefore, C.
Genes are the hereditary unit of life, which carries the information from parent to daughter cells. The organisms belonging to the same species will have the same genetic sequence.
The correct answer is:
Option C. More closely related species will have more similarities in DNA
The DNA stores the genetic information of the organisms and codes for the traits of the organism.
The genes delimit the species' relativity of the organisms. The species that are closely related will have more similarities in the genetic sequence.
The similarity of the genes or DNA is often used as an indication of descending of species from a common ancestor.
Therefore, option C is correct.

To prevent a fire hazard, ethylene oxide should only be used in an area without sparks or flames. Thus, the correct option for this question is D.
What is ethylene oxide?Ethylene oxide may be defined as a type of highly flammable gas that is significantly utilized in order to sterilize medical equipment. It is a colorless gas with a sweet odor.
It is used primarily to produce other chemicals, including antifreeze. In smaller amounts, ethylene oxide is used as a pesticide and a sterilizing agent.
As this ethylene oxide is a highly flammable gas one must be required to keep this in a place or an area that is free from sparks or any other kinds of flames.
Therefore, to prevent a fire hazard, ethylene oxide should only be used in an area without sparks or flames. Thus, the correct option for this question is D.

What is kinetic energy and how is kinetic energy related to the temperature of a substance?
Answer:
Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass. The temperature of gases is proportional to the average translational kinetic energy of atoms and molecules. The motion of individual molecules in a gas is random in magnitude and direction.

does aerobic and anaerobic respiration have the same number of carbons, hydrogens and oxygens? Explain.
The fundamental difference between aerobic and anaerobic respiration is the usage of oxygen in the process of cellular respiration. Aerobic respiration, as the name suggests, is the process of producing the energy required by cells using oxygen. The by-product of this process produces carbon dioxide along with ATP – the energy currency of the cells. Anaerobic respiration is similar to aerobic respiration.
isabella works for an environmental safety group. her group wants to answer the question “to what lengths must we go to protect plants and animals?” why is her groups research question flawed?
Answer:
In this case, the question asked is "To what lengths must we go to protect plants and animals?", which is not specific and cannot be used for scientific research.
The ecological researches for the safety of the environment involves the protection of the plants and the animals on the basis of their number and vulnerability to extinction. Almost all the length of the plants are ecologically important and can decrease in number due to the changes in the environment, the length is not a parameter to determine the protection boundary.

Which statement about DNA is NOT correct?
O DNA is found in the nucleus of eukaryotes
O DNA is single stranded
O Deoxyribose is the sugar in DNA
o there are two single ring nitrogen bases in DNA
Answer:
B (2nd Option): DNA is single-stranded
Explanation:
A is correct: DNA is indeed found in the nucleus of eukaryotes.
B is incorrect: Although there can be single strands of DNA (ssDNA), DNA is usually double-stranded which is how it forms its characteristic double-helix shape.
C is correct: Deoxyribose is indeed the sugar in DNA (Deoxyribonucleic Acid)
D is correct: The two single ringed nitrogenous bases in DNA are thymine and cytosine, while the other two (Adenine and Guanine are double ringed.

Hello?? Can anyone help me??! PLEASE
Answer:
The temperature is staying the same. In the graph when it shows solid/liquid and liquid/gas, the temperature stays the same until it changes. This is because it reached it's melting point/vaporizing point. For example, a solid gets heated up, it then reaches it's melting point but it can't go higher than that because it isn't fully a liquid yet, once it's a liquid it will then continue to rise in temperature.

Osmosis is considered to be a type of
active transport

exocytosis
Answer:
Osmosis is considered to be a type of
active transport.
Explanation:
Answer:
passive transport
Explanation:
Osmosis is the process in which water molecules move from a region of higher water potential to a region of lower potential down a water potential gradient across a partially permeable membrane, so little energy is required to carry out this process, thus it is a form or passive transport.
Patients with a genetic condition known as cystic fibrosis struggle with symptoms such as lung and digestive problems. At the cellular level, the cells of patients with the disease do not transport water or other materials out of the cell efficiently. Therefore, patients’ cells have a build up of water and other substances inside the cell. Which of the following best describes how cystic fibrosis impacts cells?
Answer:
One pair of chromosomes includes a gene called the cystic fibrosis transmembrane conductance regulator (CFTR) gene. This gene is large and complex — in fact, more than 1,000 different CF-related mutations have been identified.
In most people, the CFTR gene helps regulate the flow of salt and fluid in and out of cells. But if there is a mutation in this gene, chloride, a component of salt, gets stuck inside the cells and a thick, sticky mucus starts to build up inside the body.
