Lipid tails stay untangled because
could two individuals with type A blood ever produce any offspring with type O blood?
Yes, it is definitely possible that two individuals with type A blood ever produce any offspring with type O blood.
What is a Blood group type?A blood group type may be characterized as the classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells. In humans, there are four types of blood groups are there.
A blood group: [tex]I^AI^A or I^AI^O[/tex]. B blood group: [tex]I^BI^B or I^BI^O[/tex]. AB blood group: [tex]I^AI^B[/tex]. O blood group. [tex]I^OI^O[/tex].The blood grouping in humans is an example of co-dominance. The blood group of an individual or offspring is determined by the respective blood group of its parents. Parents with type A blood have the probability to produce any offspring with type O blood in the sense that they fuse their both specific gametes of [tex]I^OI^O.[/tex]
Therefore, it is definitely possible that two individuals with type A blood ever produce any offspring with type O blood.

which level of tornado tornados causes the greatest damage?
A: EF0
B: EF1
C:EF5
D:EF10
Answer:
The correct answer is C:EF5.
Explanation:
The Tornado is a meteorological phenomenon that consists of a whirlwind of wind produced as a result of an air rotation of great intensity and of little horizontal extension, which extends from the base of a mother cloud. The Fujita-Pearson scale and the so-called Enhanced Fujita Scale classify tornadoes according to the damage caused. The Enhanced Scale (EF) was a refinement of the old Fujita scale, using wind estimates and better damage descriptions; however, it was designed so that a tornado rated on the Fujita scale would receive the same numerical rank, and was implemented beginning in the United States in 2007. An EF0 tornado, the weakest on the scale, possibly damages trees but not structures, as long as that an EF5 tornado, the strongest, it can cause incredible devastation; it can rip buildings off their foundations, exposing them and even deform skyscrapers. The wind speed in a tornado can reach 500 km / h.

Why is mRNA made from DNA? Hint: What can it do that DNA cannot do?
Answer:
Once RNA polymerase is done, the mRNA transcript has to be processed before it can make its journey out of the nucleus and to the ribosome.
Explanation:
Answer: double compared to single
Explanation: NA is made up of deoxyribose sugar while mRNA is made up of ribose sugar. DNA is present in the nucleus while mRNA diffuses into the cytoplasm after synthesis. DNA is double-stranded while mRNA is single-stranded.

Using the diagram below, what percentage of the human body is inorganic material?
O A. 25
O B. 68
O c. 74
o D. 32
The percentage of the human body is inorganic material - B. 68.
The primary difference between organic and inorganic compounds is that organic molecules always contain carbon while most inorganic compounds do not contain carbon.
nearly all organic compounds contain carbon-hydrogen or C-H bonds.inorganic compounds include water, carbonic acid (H2CO3), and salts thereof.water is an inorganic molecule as well as ions and salts.Protein carbs and lipids are organic molecules.Thus, the percentage of the human body is inorganic material - B. 68.

What are some future treatments that are on the horizon?it about Cancer
Answer:
New discoveries in the treatment of cancer do not only centre on conventional medicine. In our haste to get to grips with a cure for cancer, natural products may be overlooked and dismissed in the fight against such an aggressive disease.
In December, the Academy of General Dentistry reported that a new study had found that simply swishing green tea around the mouth halts the growth of new oral cancer cells and breaks down and kills existing oral cancer cells. The antioxidants (polyphenols) in the tea work to remove the free radicals or oxidants and prevent gene mutations, and as an added bonus, the polyphenols can kill cancerous cells without harming normal cells and inhibiting their growth. Similarly, a chemical found in tomatoes may prevent or treat oral cancer and one derived from soybeans has been found to shrink abnormal growths that lead to cancer. While these are not cures, their activity may in the future lead to therapies that compliment conventional treatment modalities.
Perhaps combining ancient remedies with Western scientific advances is the way forward to finding an effective cure for cancer. Combrestatin – a cancer-fighting drug made from the bark of an African tree – is performing with dramatic effects in tests. The active ingredient extracted from the bark attacks the blood vessels that grow with tumors, while leaving normal blood vessels alone.

The concentration of 2 will increase inside the cell.
The concentration of O2 will remain the same outside the cell.
The concentration of CO2 will remain the same inside the cell.
The concentration of CO2 will decrease outside the cell.
Answer:
The concentration of O2 will increase inside the cell
Explanation:
Due to their kinetic energy, molecules in a gas, liquid, or solid are always in motion, and the concentration of O₂ will increase inside the cell, hence option A is correct.
What are distribution molecules?There is continual movement and collision between molecules, the molecules move randomly as a result of these collisions. A continuous fluctuation of a number of substances in their relative proportions up to what is known as the limit for solubility,
More molecules will eventually be pushed into the less concentrated area. The term "solution" is most often used to describe the liquid state of matter, however, mixes of gases and solids are conceivable.
Therefore, oxygen diffuses into tissues because its concentration is higher in the blood than inside the tissue, hence option A is correct.

Proteins contain a wide range of functional groups.
An important difference between sexual and asexual reproduction is____
Answer:
The number of offspring and the time required to generate them.
Explanation:
The number of off springs and time required to generate them is the right answer.
What is sexual and asexual reproduction?In sexual reproduction, the offspring inherit a combination of genes from both parents, which can lead to the expression of new traits and the evolution of new species. In asexual reproduction, the offspring inherit the same genes as the parent, so there is little potential for genetic variation and evolution.
Asexual reproduction is often seen as less efficient than sexual reproduction because it does not allow for the exchange of genetic material that can help organisms adapt to changing environments.
