Answer:
2.41 × 10^24 molecules
Explanation:
To calculate the number of molecules of a substance (nA), we multiply the number of moles of such substance (n) by Avagadro's number or constant, which is 6.02 × 10^23.
That is; nA = n × 6.02 × 10^23.
In this question, 4 moles of glucose were given. The number of molecules in 4 moles of glucose is as follows:
nA = 4 × 6.02 × 10^23
nA = 24.08 × 10^23
nA = 2.41 × 10^24 molecules.

In a certain animal, a breed is known that always has a hairy tail; another breed is known that always has a naked tail. How would you determine which trait is dominant?
the dominant trade should be the hairy tail if its seen more often, naked tails are resesive and are seen less often, hope that helped
In a certain animal, it is possible to determine a dominant trait by crossing purebred lines and observing the proportion in offspring.
What are purebred lines?The purebred lines are genetic lineages of organisms that are homo-zygous for a given genetic/phenotypic trait.
It is possible to determine the dominance level of phenotypic features by crossing purebred lines.The proportion of the phenotypic traits in progeny will evidence the presence of dominace.In conclusion, in a certain animal, it is possible to determine a dominant trait by crossing purebred lines.

Drag each tile to the correct location.
Identify each process as a carbon source or a carbon sink.
Carbon sources are any natural or artificial production site of carbon and/or any chemical compounds composed of carbon, such as carbon dioxide and methane.
Carbon source: Combustion,Respiration.
A carbon sink absorbs carbon dioxide from the atmosphere.
Carbon sink: Photosyntheis,Ocean absorption,Fossilization.
Which one is carbon sink or carbon source?1. Photosyntheis: Forests are typically carbon sinks, places that absorb more carbon than they release. They continually take carbon out of the atmosphere through the process of photosynthesis.
2. Ocean absorption: Phytoplankton are the main reason the ocean is one of the biggest carbon sinks. These microscopic marine algae and bacteria play a impotant role in carbon cycle - absorbing carbon.
3. Fossilization: Absorb CO2.
4. Combustion: Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives off heat and CO2 in environment.
5. Respiration: The respiratory system, with its conduction and respiratory zones, brings air from the environment to the lungs and facilitates gas exchange both in the lungs and within the cells and gives out CO2 in atmosphere.
Thus, we can conclude that
carbon sink: Photosyntheis,Ocean absorption,Fossilization.
carbon source:Combustion,Respiration.

¿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,

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.
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.

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.

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.

If an organism's body cells have 12 chromosomes, how many chromosomes will sex cells have? Explain.
Answer:
6 chromosomes
Explanation:
Answer:
The gametes or sex cells produced by the organism will have 6 chromosomes if the organism has 12 chromosomes.
Explanation:
The diploid organism has all chromosomes in pairs, one chromosome inherited from male parent & another chromosome in the pair is inherited from the female parent. If an organism has 12 chromosomes, it has 6 different types of chromosomes, differing from one another in length, the position of centromeres and genes present on these. Six different types of chromosomes constitute a haploid set of chromosomes. Two chromosomes of the same type are called homologous chromosomes and these constitute a homologous pair. The cells producing sex cells or gametes undergo meiosis (reduction division) so that each gamete contains only one chromosome of a homologous pair. The gametes are haploid, having half the number of cells as compared to somatic cells.
