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.

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.

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
¿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,

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.

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
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.

Explanation:
the evaporation plays a huge role in the water system
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.

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.

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.
how does skin help with homeostasis? include the terms stimulus and response
Answer:
The skin provides a protective layer for the inner organs, helps to regulate temperature, water balance, receives sensory stimuli, produces vitamins, etc.
Explanation:
The integumentary system can be defined as an organ system composed of different organs, i.e., skin, hair, exocrine glands, nails. The skin helps in homeostasis by providing a protective layer for the inner organs, contains immune cells involved in immune responses, regulates temperature, water balance, receives sensory stimuli, production of vitamins. The skin contains sensory receptors for different stimuli including touch, pain, pressure, and temperature (both heat and cold receptors). The inflammatory response (inflammation) occurs when harmful microorganisms penetrate the skin, thereby causing skin inflammation. The skin's immune cells include, among others, neutrophils (located in the reticular dermis), macrophages (papillary and reticular dermis), T lymphocytes (epidermis and papillary dermis), Langerhans cells (epidermis), etc.

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.
