How is your weight different on Earth and on the moon
Answers
Answer:
Your weight on the Moon is 16.5% what you would experience on Earth
Explanation:
Answer:
To find the weight on the moon, we divide the weight on earth by the earth's force of gravity, which is 9.81m/s2. ... So an object or person on the moon would weigh 16.5% its weight on earth. Therefore, a person would be much lighter on the moon. Conversely, a person is 83.5% heavier on earth than on the moon.
Explanation:
Also:The mass of an object will not change if the gravitational pull on the object changes, but the weight of the object will. ... But if you measure your weight on the Earth and on the moon, your weight will be far less on the moon because of a weaker gravitational force,

Fluffernutter labradors are identical to Earth labradors in every way, except that they grow marshmallows instead of fur. The three possible types of marshmallow skin are: a. Black (tastes like licorice); b. Chocolate (tastes like chocolate); c. Yellow (tastes like vanilla). There are two genes that control for this phenotype, acting in a recessive epistatic manner. The two-locus genotypes that correspond to the phenotypes are:
Answers
Answer:
Alleles at the two genes/loci:
- Locus 01: A (dominant), a (recessive)
- Locus 02: B (dominant), b (recessive)
A_B_ (Licorice)
aaB_ (Chocolate)
__bb (Vanilla)
Explanation:
Recessive epistasis is the genetic interaction phenomenon where recessive alleles at one locus mask the phenotypic expression of another gene locus. In a recessive epistatic interaction between two genes, the phenotypic ratio of the three resulting phenotypes is 9: 3: 4. In this case, there are two genes responsible for the three phenotypes Licorice, Chocolate, and Vanilla. One locus is responsible for determining if Fluffernutter labradors will be Licorice or Chocolate. Licorice is dominant and will be expressed if the Fluffernutter labrador has a AA or Aa, while Chocolate is recessive and therefore it is expressed only in aa Fluffernutter labradors. However, the expression of the phenotype is determined by another gene pairing. The epistatic allele b in homo-zygous condition will produce Fluffernutter labradors with Vanilla phenotype.

The cell cycle can be explained as a sequence of events by which a cell duplicates its genome, synthesizes other cell constituents, and eventually divides into two daughter cells.
explanation
The two primary phases of the cell cycle are
1. The interphase It is the phase between two successive M phases. It follows cytokinesis. It is divided into G1, S, and G2 phases.The DNA replication occurs in the S phase of the interphase2. The M phaseThe M phase has four stages
ProphaseMetaphaseAnaphaseTelophaseCytokinesis follows the M phase.
The prophase is the first stage of the M phase. Here, the initiation of condensation of chromosome material takes place. As a result of this, the mitotic spindle is developed. The metaphase is characterized by the complete disintegration of the nuclear envelope. And, the chromosomes move to the spindle equator. In anaphase, two daughter chromatids are formed from the chromosomes. Telophase is characterized by the decondensation of the chromosome material and the formation of two new nuclei (Karyokinesis) and as a result, the mitotic spindle disappearsThe cytokinesis is the last step. Here, the cell gets divided into two daughter cells. In animal cells, it can be achieved by the appearance of a deep furrow in the plasma membrane. However, plant cells require a cell plate as they are enclosed by a cell wall.ConclusionSo, the final answers are,
Interphase - Replication of DNA and follows the cytokinesis.Prophase - Formation of the mitotic spindleTelophase - Mitotic spindle disappears as two new sets of chromosomes arrive at the opposite poles.Cytokinesis - The cell is split into two daughter cells and plants require the formation of a cell plate.PLZ HELP WITH SCIENCE WORK Don't give me a link Plz JUST ANSWER

h. phosphorylation
i. methylation
j. GMP
e. CMP
Answers
Answer:
Thymine in DNA occurs as the result of thymidylate synthase creating deoxythymidine monophosphate (dTMP), which then undergoes phosphorylation to deoxythymidine diphosphate (dTDP), then to Deoxythymidine triphosphate (dTTP), and incorporated into DNA by the DNA polymerase (DNA pol). Thymine in tRNA arises post-transcriptionally, by S-adenosylmethionine-dependent methylation of a uridine 5'-monophosphate (UMP) residue in RNA.
Explanation:
Thymidylate synthase is an enzyme involved in de novo DNA synthesis. This enzyme (thymidylate synthase) catalyzes the transfer of the one-carbon group from 5,10-methylene-tetrahydrofolate (5,10-CH2-THF) to deoxyuridine monophosphate (dUMP) and subsequent methylation to produce deoxythymidine monophosphate (dTMP), which is then phosphorylated to deoxythymidine triphosphate (dTTP) by kinases and incorporated into DNA. On the other hand, specific tRNA methylases catalyze the methylation of transference RNA (tRNA) by using S-adenosylmethionine as a methyl donor. Since tRNA methylation is a post-transcriptional modification, this chemical reaction is considered an epitranscriptomic modification on the RNA molecule.

After many years of normal function, a cell begins producing different proteins than it produced before. Propose two different explanations for this change.
Answers
Answer:
Explanation:
In order to produce different proteins, mutations must occur in the genetic material of the cell. We distinguish gene and chromosome mutations. Mutations in the level of genes are called point mutations because only one to several nucleotides are changed. These processes are known as deletion, insertion, and substitution. Mutations can also appear in chromosomes altering their number and structure. There are four types of mutations: deletion, duplication, inversion, and translocation.
Cells are the functional unit that has a specific activity to perform. The alteration of the cell function can be due to gene or chromosomal mutations.
What are gene and chromosomal mutations?A change in the sequence of the DNA of the gene causes gene mutation and affects the gene or the part of the DNA of the chromosome. They occur in a single place and are called point mutations.
The point mutation is the alteration, addition, deletion or inversion of the single nucleotide base pair of the gene.
The chromosomal mutation affects the whole chromosome and alters the shape and size of the chromosomes. It leads to the increase or the decrease of the ploidy and structural shape.
Chromosomal mutation can be due to translocation, deletion, inversion and duplication of the chromosomes. Their increase or decrease affects the genome as a whole.
Therefore, alteration of the cell can be due to chromosomal or gene mutation.

To provide the developing fetus with food, water, and oxygen is the function of placenta. Therefore, option (D) is correct.
What do you mean by placenta?An organ that grows inside the uterus during pregnancy is the placenta. A developing infant receives oxygen and nutrients from this structure.
As your womb gets smaller, your placenta will fall out and the blood vessels that were holding onto it will close. This assists with forestalling a lot dying - despite the fact that draining a little is ordinary.

On a geology field trip, Toccara’s class studies a sedimentary rock formation. Is it possible that material from this sedimentary rock could ever form igneous rock?
Answers
Answer:
It is possible for material from a sedimentary rock to become an igneous rock through a process called metamorphism.
Explanation:
It is possible for material from a sedimentary rock to become an igneous rock through a process called metamorphism. Metamorphism is the process of change in the structure, texture, or composition of a rock as a result of being subjected to high pressure, temperature, or both. During metamorphism, the original sedimentary rock is subjected to heat and pressure that is sufficient to cause the minerals in the rock to recrystallize into a new rock with a different composition and structure. If the conditions of metamorphism are high enough, the metamorphosed rock may become an igneous rock. This process can take place deep underground, where the rock is subjected to high temperatures and pressures due to the weight of the overlying rock and the heat of the Earth's interior.
If the Earth did not spin what would happen?
Select one:
a. The Earth's wind would bend due to gravity.
Ob. The Earth would only have two large convection currents.
Oc. The Earth would have the same temperature throughout.
Od. The Earth would have several difference convection currents at different latitudes.
Answers
Answer:
B. The Earth would only have two large convection currents. The power of Earth's spin to turn flowing air is known as the Coriolis Effect. If the Earth didn't spin, there would be just one large convection cell between the equator and the North Pole and one large convection cell between the equator and the South Pole.
Explanation:
At the Equator, the earth's rotational motion is at its fastest, about a thousand miles an hour. If that motion suddenly stopped, the momentum would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes.
If the planet stopped suddenly, everything on the surface would be destroyed, as the atmosphere, oceans and anything not nailed down kept spinning. Even braking to a halt over a minute would mean everything experienced a sideways deceleration of three-quarters of Earth’s gravity, so ‘down’ would feel like it was at an angle of 38° from the vertical. That’s enough to knock over most buildings.
If it slowed down over several years, it would still be a disaster. Without centrifugal force, the oceans would move towards the poles, dropping ocean depth by 8 km around the equator. Since this is less than the depth of the ocean there, Earth’s water would be divided into two huge polar oceans separated by a belt of land in the middle. Everything north of Spain would be underwater, as well as all of Antarctica.
Once Earth doesn’t spin on its own axis, a day lasts as long as a year. Everywhere receives six months of daylight, gradually heating up the planet to well over 100 °C. The huge central continent would get the hottest, and any remaining lakes and rivers would boil away and be blown to the poles by fierce winds. Even primitive life would only be possible along a narrow strip at the coast.

A plant's roots absorb water from the nearby soil. This is the best example of how living things play a role in the water cycle. Thus, the correct option is A.
What is Water cycle?The water cycle is the biogeochemical cycle which shows the continuous movement of water within the Earth and its surrounding atmosphere. Water cycle is a complex system that includes many different processes such as evaporation, precipitation. Liquid water evaporates into the form of water vapor, condenses back to form clouds, and precipitates back to the earth in the form of rain and snow particles.
Plants absorb water from the soil. The water then moves from the roots through the stems to the leaves of the plant. Once, this water reaches the leaves, some of it evaporates from the leaves, adding to the amount of water vapor in the atmosphere. This process of evaporation through the plant leaves surface is called transpiration.
