In what ways do compounds differ from elements
Answer:
A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom. Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds.

What happens to a rock formation that undergoes a repeated and frequent freeze and thaw cycle of water?
A: Sinkholes form which is part of the chemical weathering process.
B: Deposition occurs which is part of the chemical weathering process.
C: Abrasion occurs which is part of the mechanical weathering process.
D: Ice wedging occurs which is a part of the mechanical weathering process.
Answer:
its A (Sinkholes form Which is a part of the Chemical weathering process)
Explanation:
How do I know you may ask well I've done the test yesterday and that's what I picked and I got it right:)
Weathering is a process of disintegration of the rock by atmospheric exposure. Repeated and frequent freeze and thaw cycles of water cause ice wedging. Thus, option D is correct.
What is mechanical weathering?Weathering can be physical, mechanical, or chemical. Mechanical weathering involves the erosion or the disintegration of the parent larger rocks into smaller sediments of the small rocks. It involves either solidified or liquid water as a key agent to deteriorate the rock.
Ice wedging is a mechanical weathering that involves seeping and falling of the cold water or precipitation over an area that repetitively and frequently gets frozen and thawed over and again.
This water gets deposited and causes wedges to form in the parent rock. The cracks are formed that erode and disintegrate the rocks into smaller pieces.
Therefore, option D. ice wedge is formed by mechanical weathering.

Which mRNA modification is likely absent if the mRNA is degrading prematurely from the 5 end of the mRNA?1) splicing together of exons.2) addition of the 3' polyadenylated tail.3) addition of the 7-methylguanosine cap to the 5 end.4) RNA editing.5) removal of introns.
Answer:
3) addition of the 7-methylguanosine cap to the 5 end
Explanation:
The 7-methylguanosine (m7G) cap is a modified methylated version of the Guanosine (G) nucleotide which is located on the 5′-terminus of the eukaryotic messenger RNA (mRNA). The m7G cap plays a key role in mRNA translation in eukaryotic organisms, from yeasts to mammals. During mRNA processing, m7G cap is added at the 5' end in order to protect mRNA from degradation by nuclease enzymes. Moreover, this cap also enables the proper attachment of the mRNA molecule to the ribosome during protein synthesis.

Leukopenia is a condition characterized by a decrease in white blood cells. What effect does leukopenia have on the body's ability to fight infection?
Leukopenia increases the body's ability to fight infection.
Leukopenia decreases the body's ability to fight infection.
Leukopenia has no effect on the body's ability to fight infection.
Leukopenia increases the body's ability to fight infection at certain times and decreases it at other times.
Answer:
Leukopenia decreases the body ability to fight infection
Explanation:
There are three major types of cells in the blood namely: platelets, red blood cells (erythrocytes) and white blood cells (leucocytes). These cells perform individual functions in the blood tissue, however, the cell saddled with the responsibility of fighting against foreign bodies and preventing the body against infection is the WHITE BLOOD CELL (LEUCOCYTES).
According to this question, Leukopenia is a condition characterized by a decrease in the number of white blood cells in the blood. The effect of this decrease in number of white blood cells caused by Leukopenia is a DECREASE IN THE BODY ABILITY TO FIGHT INFECTION.

Which medium grain sized metamorphic rock is composed mostly of the same mineral as the sedimentary rock limestone?
Answer:
Explanation:
Marble
Calcite-containing dolostone has undergone a metamorphosis to become marble (or dolomite), white marble develops when the limestone is pure.
What is a metamorphic rock?Calcite or dolomite recrystallization often results in bigger interconnecting crystals. Despite having a similar appearance to quartz, marble and quartzite are more softer than quartz.
By changing limestone under heat and pressure, marble is a metamorphic rock. As interlocking grains expand, the calcite in the limestone changes, and the original limestone's layers and fossils vanish.
Therefore, marble, when limestone, a sedimentary rock, is buried for millions of years under great pressure and heat, marble, a metamorphic rock, can be created.

Suppose that a mouse with black fur has both an allele for black fur and an allele for white fur (Bb). Based on this information, you can conclude that the dominant allele must be for fur andthe recessive allele must be for fur.
Answer:
Dominant black fur and recessive white fur
Explanation:
Black fur is showing over white fur so it is a dominant trait and white is recessive
Answer:
The dominant must be for the black fur and the recessive must be for the white fur.
Explanation:
A variation of a gene, which will generate a certain phenotype, even in the existence of other alleles is known as a dominant allele. On the other hand, a version of a gene that needs to be when inherited in order to be articulated in the phenotype is known as a recessive allele. The offspring will not express the phenotype of the recessive allele if it is inherited together with a dominant allele, that is, the phenotype of the dominant allele will just be expressed.ASAP I NEED IT LIKE RN

What is Population?
Population is the number of people in a single area, be it a city or town, region, country, continent or the world. A population is any complete group that has at least one characteristic in common. They are not just people.
It may consist of, but is not limited to, people, animals, businesses, buildings, motor vehicles, farms, objects or events. It is an average calculated from an entire group, distribution, or population that is obtained by dividing the sum of all population variables by the total number of variables in the population.
Here μ is the population mean. ∑X is the sum of all the observations in the space.
Thus, a peacock spreading and shaking his feathers to attract a female represents an activity within a population. So, the correct option is (D).
