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.

do DNA and RNA have the same phosphate group?

Answers

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.

¿A qué se debió el incremento en la cantidad de oxígeno en la atmósfera hace miles demillones de años?

Answers

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.

Are identical twins mutations? And why

Answers

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:

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

Answers

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

Explanation:

why must both constricting and posionous snakes eat their prey alive?

Answers

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.

V. Basal cell.

VI. Vallate papilla.

VII. Olfactory.

VIII. Sustentacular cell.

IX. Cranial nerve I.

X. Cranial nerve VII.

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 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?

Answers

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.
