Answer:

The correct answer is Archaea and Eukarya.

Explanation:

On the basis of the information provided in the question, the ultimate branch of the phylogenetic tree starts with the line of Eukarya and then possesses the species of the Archaea division that comprises those prokaryotic species, which thrives in extremely tough environmental scenarios.  

As the last branch possesses species of two domains, that is, Eukarya and Archaea and it starts with Eukarya and afterward holds the species of Archaea, which shows that both Eukarya and Archaea are associated genetically.  

According to the phylogenetic tree presented, Eukarya evolved from the second branch of the tree, which contains species of the Eukarya domain and contains diplomonads, microsporidia, etc.

What is the significance of the eukarya?

This includes the eukaryotes, where it is one of the three main domains of life and it is significant because it contains all the organisms that have a true nucleus as well as the organelles, and they are plants, animals, fungi, etc. They range from simple single-celled organisms such as amoebas to complex multicellular organisms such as humans, and they are crucial for understanding evolution.

Hence, according to the phylogenetic tree presented, Eukarya evolved from the second branch of the tree, which contains species of the Eukarya domain and contains diplomonads, microsporidia, etc.

The ocean acts as a heat storage location, termed 'ocean heat storage', due to its high heat capacity. It effectively moderates Earth's climate, absorbing heat and minimizing temperature extremes. Ocean heat content influences sea surface temperature, sea level, and currents.

The Role of the Ocean in Earth's Heat Budget

The term that describes the ocean as a storage location for heat is ocean heat storage. Oceans have a vast capacity to absorb and store heat due to their large heat capacity, making them significant regulators of Earth's climate. This large heat capacity not only diminishes seasonal temperature variations but also has a notable impact on climate on longer timescales. Ocean heat content determines various climate factors such as sea surface temperature, sea level, and currents.

Furthermore, the property of water that enables oceans to act as heat reservoirs is its high specific heat capacity. This allows the oceans to absorb a large amount of heat with little change in temperature, influencing the Earth's climate by moderating temperature extremes. The thermal energy transported by ocean currents varies and has historically played a key role in climate phenomena like the development of ice ages.

With about 90% of the observed increase in Earth's heat content going into the ocean, it is clear that the oceanic heat budget is a critical concept in understanding global climate patterns and their variations.

The prophase of mitosis consists of the condensation of the chromatin that is present in the cell. This chromatin condenses in order to ready itself for replication, and forms structures called chromosomes. Each chromosome consists of two chromatids.

Therefore, if there are 5 chromosomal pairs, there are 10 chromosomes. Each chromosome has two chromatids, which means that there are 20 chromatids.

The number of sister chromatids at the prophase of mitosis will be 20.

Further Explanation:

The cell cycle in eukaryotes comprises two stages: the mitotic phase and the interphase. The interphase is the growth phase during which the cell content grows and doubles with the accumulation of nutrients that are necessary for mitosis.

In the G1 phase of the interphase, the proteins and nutrients required for the S phase are synthesized. During this phase, the cell grows but does not undergo division. G1 phase is followed by the S phase during which replication of the DNA occurs and the cell's DNA content or the chromosome number doubles. The G2 phase is the cell's checkpoint to ensure that the DNA replication has been accomplished successfully with no damage. It also synthesizes protein machinery for the M phase for cell division to take place. In the M phase, the cell division occurs separating the DNA content equally into two daughter cells produced at the end of mitosis.

Here, the diploid cell has 5 pairs of the chromosome or the DNA content is 2n = 10. Each chromosome will have two chromatidsthat are joined at the centromere in the G1 phase.

After the S phase, the DNA content will double and each chromosome will comprise an identical sister chromatid pair. Therefore, there will be 20 sister chromatids after the completion of S phase or replication.

The M phase will start with the prophase containing 20 sister chromatids, two pairs from each chromosome. The sister chromatids will move towards the opposite pole and eventually divide into two daughter cells with an equal amount of DNA content (2n=10).

The father's phenotype(physical trait) is wet earwax and the mother's phenotype is wet earwax as well.

Answer:

a) Wet ear waxed father

b) Wet ear waxed mother

Explanation:

Having wet earwax is a dominant trait in humans , represented by "W"

Having dry earwax is a recessive trait in humans , represented by "w"

When a dominant and recessive trait occur together, only the trait associated with the dominant allele is expressed.

Now  a cross is being carried between two parents having following genotype

Father - "WW"

Mother - "Ww"

a) The fathers phenotype would be "wet earwax" as both the alleles "W" are dominant allele and thus father is a "dominant wet ear waxed homozygous father"

b) The phenotype of mother is "Wet earwax" as when a dominant and recessive trait occur together, only the trait associated with the dominant allele is expressed. Thus, mother is a "wet ear waxed heterogyzous mother"

The amount of OXYGEN dissolved in ocean waters quickly decreases with depth
to reach a minimum at around 1000 m of depth.
phytoplanktonic organisms produce enormpus amounts of oxygen through photosynthesis.
But oxygen is also used up very quickly by animals that live in the water:
at depth (beyond the photic zone, around 100 m)
oxygen can not be produced (lack of sunlight) and whatever amount is present is rapidly consumed:
as a consequence, oxygen is quickly depleted below 100 m
in the Bathypelagic and the Abyssopelagic zones there are less and less consumers, so oxygen is not used up at the same rate it is in surface waters.
In shallow waters there is plenty of sunlight, and as a consequence
nutrients are depleted pretty quickly by the abundance of marine life.
As soon as we move below the photic zone, where animal life decreases significantly,
nutrients start to increase again, reaching a maximum by the base of the Mesopelagic zone,
essentially in coincidence with the oxygen minimum.
Past that point, nutrients decrease very slowly because only few organisms live there.
At these depths, organisms are not very abundant because of the harsh conditions for life we encounter here:
they can survive, with no light at all and under enormous hydrostatic pressure,
only because of the presence of oxygen brought at depth by deep currents (which are, again, density-driven)
and of the slightly increased amounts of nutrients.
This diagram shows the variations of oxygen and nutrients (here represented by the phosphate ion) with depth in ocean waters.
surface-water circulation
Surface-water circulation is wind-driven: the wind drags the surface waters of Earth's oceans in gigantic gyres
centered in the northern and southern Atlantic and Pacific Oceans and in the southern Indian Ocean.
These gyres rotate clockwise in the northern hemisphere and counter-clockwise in the southern hemisphere (Coriolis effect).
We have already seen that surface-water circulation is wind-driven.
Deep-water circulation instead is density-driven
This means that differences in water density cause motion of water masses at depth.
Density (mass over volume) changes with changing salinity and temperature of the ocean:
higher salinity implies higher density (and viceversa)
while higher temperatures imply lower density.
Tropical waters are warmer than polar waters because of more intense solar radiation around the equator:
as long as surface waters are warm, they can never sink to the bottom of the ocean.
Surface waters can only sink to the bottom when their density is the same or higher than that of deep waters.
This happens for instance in the North Atlantic ocean, where the formation of ice pack
causes a very cold water mass to slightly increase its salinity (and hence its density);
and all around Antarctica, where the extremely cold temperatures create similar conditions.
In the figure, pink indicates warm waters, while blue indicates cold waters.
while darker pink indicates waters that are always warm (tropical waters, between about 30°N and 30°S).
Light blue indicates the North Atlantic Deep Water, a very dense body of water that sinks to the bottom
but is still less dense then the Antarctic Bottom Water (in darker blue)
a higher amount of solar radiation reaches Earth around the equator,
where temperatures are on average higher than at higher latitudes.
We would expect that higher temperatures in ocean waters would cause
a greater amount of water evaporation, and therefore an increase in ocean salinity.
But when we observe salinity variations, we notice that the higher values
are found around 23° of latitude instead.
This occurs because of the high level of precipitation in equatorial areas, where rain water dilutes the salinity of the ocean.
Areas around the tropics, up to 30° N and S, are extremely dry (that is where most of Earth desert are found).
While the heat is still enough to cause substantial evaporation,
precipitation is extremely scarce or absent.
The consequence is an increase in salinity at these latitudes (known as the tropics).
The density of the ocean water is affected mainly by its temperature and its salinity.Temperature and salinity vary consistently with latitude only at the surface.At depth they remain essentially constant, and as a consequence the density too does not change much.In this graph we can see how density of the ocean waters,when measured at low latitudes (solid red line) increases quickly between ca. 100 m and 1000.This vertical interval of rapid density increase is defined as the pycnocline.where mixing with the atmosphere occurs.Below the mixed layer we distinguish between upper and deep waters: the Upper water coincides with the pycnoclineand is found above what is called the Deep water, where conditions are more stable

The first one, Added removed or changed. Mutation as in anything that would cause the slightest change. 

A mutation within a gene can occur as a point mutation, involving a single base pair with deletions, insertions, or substitutions. An insertion or deletion, or indel, can change the number of DNA bases, possibly leading to a frameshift mutation which disrupts the protein coding sequence.

Mutations within a gene can occur in several ways. A mutation that involves the change of a single base pair is known as a point mutation. This can happen through base pair deletions, insertions, or substitutions. Base pair substitutions involve the alteration of a single nucleotide, resulting in a transition (one purine or pyrimidine is replaced by another of the same kind) or a transversion (a purine is replaced by a pyrimidine, or vice versa).

Another type of mutation is an insertion or deletion (collectively known as indels), where extra base pairs are added or removed. The number of base pairs affected can range from one to thousands. An insertion changes the number of DNA bases in a gene by adding a piece of DNA, whereas a deletion removes a piece of DNA.

When one or more nucleotides are inserted or deleted, it can lead to a frameshift mutation which disrupts the normal reading frame of the gene. Such mutations tend to have a more significant effect on the resulting protein than substitutions because they can change the entire amino acid sequence that follows the mutation site.

Answer: The best place to store grains to reduce the risk of cross-contamination is next to canned peaches

Options

1. Next to the frozen fish

2. Labeling and dating rejected items

3. Next to canned peaches

4. Under the ground beef

Explanation: By storing foods in a cold place, the lack of heat energy prevents microbes from growing on grain products. In addition, grains should be stored in a dry place so that the lack of moisture prevents molds and other microbes from surviving and reproducing. Finally, grains should be placed in a container in order to best avoid possible contamination by environmental microbes.

In order to best avoid cross-contamination, grains should be stored next to other canned products or by themselves. Storing it near fresh produce such as beef, fish, other protein products, or near other vegetables runs the risk of microbes from the other produce contaminating the grain. Thus, the best answer for this question is that the grains should be stored next to canned peaches to best avoid cross-contamination. Since the peaches are in a sealed container, it greatly reduces the risk of microbial transfer between these two products.

Storing grains next to frozen fish or under ground beef poses a much greater risk for contamination. Raw meat can still contain pathogenic bacteria, even if frozen. Thus, storing grains next to these products runs the risk of bacterial cross-contamination. Thus, neither of these options are the best location to store grains.

Labeling and dating rejected items is a way to keep track of food processing, but does not provide a suitable place to store grains.

Diamonds are formed deep within the earth about 100 miles or so below the surface in the upper mantle. The combination of high pressure and high temperature is what causes diamonds to form.

Diamonds that appear at the surface of the earth were brought up by very deep -seated volcanic eruption. It is a very rare and unique kind of volcanic eruption that is very violent. These eruptions occurred long ago carrying the already formed diamonds from the upper mantle to the surface of the earth.

On reaching the surface of the earth, it built up a mound of volcanic matter that eventually cooled, and the diamonds were contained within the cooled mound. These mounds are called Kimberlites and are typically the source of many of the world's mined diamonds.
