Why are people with type o blood considered universal donars?
Answer:
because they can donate blood to anyone
Explanation:
People with type O- blood are called universal donors because their donated red blood cells have no A, B or Rh antigens and can therefore be safely given to people of any blood group. ... Their plasma does not contain A or B antibodies and can be transfused safely to all blood types.
why must both constricting and posionous snakes eat their prey alive?
Answer:
There is a very common misperception among people, even among many snake hobbyists, that snakes must have live prey.
Explanation:
This is not usually true. In the wild, snakes, like most other carnivores, will usually take any opportunity to get a free and easy meal, and will not pass up a freshly killed prey animal if they happen upon it. In fact, snakes have been known to eat a fair amount of carrion which has been dead for some time, and the stomach contents of wild snakes often contain prey that must have been in an advanced state of decomposition when it was eaten. Thus, although your snake may prefer to eat live prey, which it kills itself through constriction, this is not at all necessary for the health of the snake. In fact, it is best not to feed your captive snakes live prey at all.
What would most likely result if mitosis was NOT followed by cytokinesis?
Answer:
If cytokinesis was skipped, Cells would have too many chromosomes; cells wouldn't function properly because they would be too big.

Explanation:
A sensory system can be defined as components of the central nervous system (CNS) which comprises of the brain, neural tissues or pathways and sensory neurons responsible for sensory functions, perception and processing sensory informations such as sound, light, heat, etc.
Generally, the nervous system found in living organisms such as humans, comprises of two (2) major components or systems; a central nervous system (CNS) and a peripheral nervous system (PNS).
Basically, the central nervous system (CNS) interprete the neural signals that are generated from stimuli that are detected by the sensory system. The five (5) main sense organs in the sensory system are: skin, tongue, ears, nose and the eyes. Some of the terminologies and features associated with the sensory system includes the following;
I. Adaptation: loss of sensitivity due to repeated stimuli. Stimulus can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal).
II. Filiform papilla: helps manipulate food on tongue surface. These are the thread-like dots found on the tongue and they typically cover two-third (⅔) of the human tongue.
III. Gustation: sense of taste. It is the ability of a living organism to taste flavors in a food or other things.
IV. Bowman's gland: produces mucus. It's a nasal gland found in the olfactory mucosa and responsible for the production of mucus in living organisms.
V. Basal cell: stem cell of olfactory receptor.
VI. Vallate papilla: contains taste buds for bitter substances.
VII. Olfactory: sense of smell. This is the ability of a living organism to perceive or smell something.
VIII. Sustentacular cell: supportive cell of olfactory receptor.
IX. Cranial nerve I: cranial nerve for taste.
X. Cranial nerve VII: cranial nerve for smell.
In recent years, the controversy surrounding environmental issues has decreased
Answer:
The correct answer is - the statement is false.
Explanation:
The controversy surrounding the environmental issue is increased in recent years as the use of fossil fuels and oil spills, deforestation all increased with time. Global warming increased in recent years many glaciers melt and cities submerged in the oceans. However, the controversy around global warming increased as people are not aware of the negative impacts and consider it as a hoax.

do DNA and RNA have the same phosphate group?
Answer: yes they do
Explanation: In a cell, a nucleotide about to be added to the end of a polynucleotide chain will bear a series of three phosphate groups. When the nucleotide joins the growing DNA or RNA chain, it loses two phosphate groups. So, in a chain of DNA or RNA, each nucleotide has just one phosphate group.

Are identical twins mutations? And why
Answer: Research published on January 7 in the journal Nature Genetics shows that identical twins differ by an average of 5.2 genetic mutations. ... In such studies, scientists often assume that pairs of identical twins have identical DNA, so their differences can be explained by the environments they grew up in. That's because so-called identical twins pick up genetic mutations in the womb, as their cells weave new strands of DNA and then split into more and more cells.
Explanation:
Where do organisms get the oxygen and sugar need to perform
respiration?
??
Explanation:
Almost all the oxygen you breathe comes from green plants. They produce oxygen during a process called photosynthesis. During photosynthesis green plants manufacture the sugar molecules fructose and glucose. Green plants use energy from sunlight to build sugar molecules from carbon dioxide and water

Explanation:
A new mutation arises in one person on the island of Kiribati (human population size 100,000). Assuming this particular mutation is total neutral, and assuming no gene flow, what is the probability that this mutation will eventually be lost due to genetic drift
Answer:
0.999999 ≈ 1
Explanation:
In a population ( N ) there is the presence of 2N alleles in the population also chance of fixation can be expressed as ; 1/ 2N
Therefore the probability that the mutation will be lost due to genetic drift
= 2N - 1 / 2N ---- ( 1 )
given that ; N = 100,000
back to equation 1
P ( losing mutation due to genetic drift ) = ((2*100,000) - 1 )) / ( 2* 100,000 )
= ( 200,000 - 1 ) / 200,000
= 0.999999 ≈ 1
Explain how the flow of energy is linked to entropy and how the law of conservation of matter applies to the carbon cycle
The first law of thermodynamics is equivalent to the law of conservation of energy: energy cannot be created or destroyed; the total amount of energy in the Universe is fixed. Energy can be transformed from one form to another or transferred from one place to another but the total energy must remain unchanged.
What is the ecological value of biodiversity?
Answer:
Life assistance in the environment Biodiversity supports functioning environments that include ozone, clean air and water, plant pollination, pest control, wastewater disposal, and a variety of other environmental services. Many outdoor activities, such as birdwatching, hiking, camping, and fishing, depend on our unique biodiversity.

Which of the following is not a difference between photosynthesis and cellular respiration?
Answer: D
Explanation: They both play an important role in the carbon cycle. Photosynthesis removed CO2 from the atmosphere while cellular respiration causes the release of CO2 into the atmosphere.
The others are major differences
Photosynthesis has as its products Starch and O2 while those of cellular respiration are water , CO2 and energy.
The materials needed for photosynthesis are water and CO2 while those for cellular respiration are starch and O2
Photosynthesis occurs in chloroplast while respiration takes place in mitochondria .
Thus the only non- difference is D.

¿A qué se debió el incremento en la cantidad de oxígeno en la atmósfera hace miles demillones de años?
Debido a que el hidrógeno molecular expulsado por los volcanes se difundió en el espacio, la Tierra ganó una atmósfera rica en oxígeno. Otra posibilidad es que el oxígeno se acumule debido a una disminución de gases – como el hidrógeno – que reaccionan con y por lo tanto "absorben" el oxígeno.
Explanation:
Answer: Some authors suggest the rise in oxygen about 2,470 – 2,450 million years ago was related to extensive volcanic activity,
