Answer:
[tex]x = 2.13\ cm[/tex]
Explanation:
See comment for complete question
Given
[tex]Mass = 87.2g[/tex]
[tex]Density = 8.96gcm^{-3[/tex]
Required
Calculate the edge length of the cube
First, we need to calculate the volume of the cube using:
[tex]Density = \frac{Mass}{Volume}[/tex]
Make Volume the subject:
[tex]Volume= \frac{Mass}{Density }[/tex]
Substitute values for Mass and Density
[tex]Volume= \frac{87.2g}{8.96gcm^{-3}}[/tex]
[tex]Volume= \frac{87.2cm^3}{8.96}[/tex]
[tex]Volume= 9.73cm^3[/tex]
Represent the edge length with x.
So:
[tex]Volume = x^3[/tex]
Substitute x^3 for Volume in [tex]Volume= 9.73cm^3[/tex]
[tex]x^3 = 9.73cm^3[/tex]
Take cube root of both sides
[tex]x = \sqrt[3]{9.73cm^3}[/tex]
[tex]x = 2.13\ cm[/tex] --- approximated
Hence, the edge length is 2.13cm

1. For today’s weather, it’s up to you to decide where the fronts are located. Draw the fronts on the map. Explain your reasoning.
As per the weather map of north America the regions of high and low pressure are given along with the cloudiness and range of temperatures
The warm and fold fonts are affected by the cloud covers and hence affect the temperature of the region. The cold front will be along the borer of 40 and 50°. The northeastern region shows maximum cloud cover and a low pressure. As compared to the western and southern region have have high temperatures and experienced high pressure. The winds will below from the high pressure to low pressure and hence create instability cover the north eastern parts.Hence the fronts are located north east and central zone.

White flower color is recessive to purple flower color in pea plants. If a pea plant has white flowers, what is
the genotype and phenotype of the pea plant
Answer:
An organism's genotype is its specific combination of alleles for a given gene. So, for example, in the pea plants above, the possible genotypes for the flower-color gene were red-red, red-white, and white-white. The phenotype is the physical manifestation of an organism's allelic combination (genotype).
Explanation:
hope this helps sorry if it doesn't have a good rest of your night :) ❤
The genotype and phenotype of the pea plant - pp - white flower
According to Mendel, there are two or more alleles (normally two) are responsible for the expression of a trait encoded by the gene.
One allele of the particular gene has the ability to mask the phenotypic expression of the other if present in a genotype together.The allele that masks another is called the dominant allele while the allele being masked is the recessive allele.The recessive allele express their effect only if they are present with the same allele in the genotypeIn this case, a gene that codes for flower color in pea plants is involved.The purple allele (P) is dominant over the white allele (p).It is given that the pea plant has white flower color that is a recessive allele therefore, it is clear that it has two recessive alleles p in its genotype.Thus, the genotype and phenotype of the pea plant - pp - white flower

What are the structural differences between a cockroach and a grasshopper?
Cockroaches have legs for crawling on walls and ceilings, but grasshoppers have legs for jumping. Some cockroaches have wings for flying, but most others don't. Grasshoppers have wings for making a sound, whether it's to attract a mate or to just be annoying. Grasshoppers have a body that is split into multiple segments (more than just one), while cockroaches have only like 2 body segments. Cockroaches have barbs on their legs for a sense of touch, while grasshoppers don't. The legs of a cockroach are very sensitive though. Cockroaches can survive a nuclear explosions because the rads don't affect them. But the heat from the nuclear blast will certainly kill a human, as well as a cockroach if exposed. Obviously, grasshoppers couldn't survive a nuclear explosion. The only down side to roaches surviving a nuclear explosion is them turning into radroaches, like in the Fallout game series from the game developing company, Bethesda Game Studios! If there were a nuclear explosion, then the roaches would mutate into human head sized roaches that can actually attack a human! (this is just a theory, not scientifically proven, lol)

The ecosystem services are all the benefits provided by the ecosystem to human. Otion A) habitat for wildlife is not an ecosystem service.
What are the Ecosystem Services?
When talking about ecosystem services, we are referring to the goods and services offered by ecosystems to human populations
There are different types of ecosystemic services:
Provision or supply:These are the products obtained by nature to be used or consumed, directly or with previous processing.
Among them, we can mention food, clear fresh-water, fertile soils, geotic materials, raw materials (used for clothing, construction), renewable fuels, biochemical compounds, pharmacological/medicinal resources, and others.
Regulation:Refers to ecological processes that improve life.
Among others, we might mention climate regulation, CO₂ absorption, water purification, air purification, erosion control, natural disaster avoidance such as flooding, soil formation and fertility maintenance, nutrient cycling, waste recycling, pests/plagues control, etc.
Cultural:Refers to the benefits that are not material.
Ecosystems also provide a recreational place or area to spend time, learn. They are a spiritual/religious space, a source of inspiration. They are considered to be cultural patrimony and the source of scientific knowledge.

7. Explain how the equations for photosynthesis and cellular respiration compare.
Answer: In Photosynthesis, carbon dioxide and water is yielded to glucose and oxygen. In respiration, glucose and oxygen is yielded to carbon dioxide and water. C6H12O6 (glucose) + O2(oxygen) → CO2(Carbon Dioxide) + H2O(water) + ATP energy. The products of one process are the reactants of the other. Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O. Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O.

Explanation:
A variety of opium poppy (Papaver somniferum L.) having lacerated leaves was crossed with a variety that has normal leaves. All the F1 had lacerated leaves. Two F1 plants were interbred to produce the F2. Of the F2, 249 had lacerated leaves and 16 had normal leaves. Give genotypes for all the plants in the F1, and F2 generations. Explain how lacerate leaves are determined in the opium poppy. (Section 5.2)
Answer:
The correct answer is-
F1 - AaBb (lacerate)
F2 - A_B_; A_bb; and aaB_ (lacerate)
- aabb (normal)
2. Two genes, with a dominant allele at either or both loci.
Explanation:
The given information gives THE following data:
Dominant: Lancerate leaves - AABB
Recessive: normal leaves - aabb
F1 has - all Lacerated leaves - AaBb
F2 by selfing F1:
AB Ab aB ab
AB AABB AABb AaBB AaBb
Ab AABb AAbb AaBb Aabb
aB AaBB AaBb aaBB aaBb
ab AaBb Aabb aaBb aabb
Here, 15/16 = lacerate which is 0.94 which is equal to the value of lacerate given in the question - 249/265 = 0.94
And normal 1/16 = 0.062 is almost same as 16/265 = 0.060
Thus, the genotypes of -
F1 - AaBb (lacerate)
F2 - A_B_; A_bb; and aaB_ (lacerate)
- aabb (normal)

Those organisms which are made up of more than one cell are called multicellular organisms.
These are a few examples of multicellular organisms:-
PlantsAnimalsFungiMulticellularity helps them to perform various work at the same time. To maintain the same number of cells in an organism, its body starts cell division.
It is not necessary for the host to divide all the cells at the same time.
