Answer:
Agriculture
Soil has vital nutrients for plants. As a result, it is used in agriculture to nourish plants. The roots of a plant receive nutrients from the soil to help it grow. The North Carolina Department of Agriculture and Consumer Services notes that 13 essential plant nutrients come from the soil.
Building
Soil is an important part of the building process. Soil compaction, which increases the density of the soil, is done as part of the building process. The purpose of the compaction is to improve the load support. If not done, structural failure can result. Soil can also be used as building materials such as adobe and red bricks.

why dont children look exactly like their parents?
Answer:
because parents only give the child 1/2 of their chromosomes
Explanation:
Answer:
because not exactly all genes are passed down to the child
Explanation:
Being genetically identical to the parent is most advantageous for organisms in which situation?
A.
Many offspring are needed in a very short amount of time.
B.
The environment is just like the one the parent lived in successfully.
C.
Mates cannot be found easily and the species is dying out.
D
The environment is changing and fast reproduction is needed.
Answer:
B
Explanation:
In asexual reproduction organisms give rise to genetically identical clones and reproduce in higher amounts, hence option d environment is changing and the need for fast reproduction is correct.
What is genetically identical?The children are clones of both the parent and each other. Asexual reproduction has several advantages, including the ability to fast increase the population when conditions are favorable.
There is just one parent required. During sexual reproduction, two people's genetic material is united to generate genetically diverse children who differ from their parents.
It is assumed that the genetic variety of sexually generated offspring gives species a higher chance of survival in an uncertain or changing environment.
Therefore fast reproduction is needed, because the environment is changing, and asexual reproduction makes a higher population, hence option d is correct.

8. In chickens, brown feathers are dominant over red feathers. Suppose we cross two heterozygous chickens.
Draw the punnett square and list the genotypes and phenotypes of the offspring.
I

Phenotypes of offspring:
Plz help me
Answer:
Crossing two chickens heterozygous for the trait feather color, when brown feathers are dominant over red feathers, will produce offspring with brown and red feathers in a brown:red phenotypic ratio of 3:1.
Explanation:
Knowing that in chickens brown feathers are the expression of the dominant allele (B) and the recessive allele is red (b), crossing two heterozygous individuals (Bb) will result in offspring that are likely to have brown or red feathers.
The cross can be represented by a Punnett Square:
Bb X Bb cross
alleles B b
B BB Bb
b Bb bb
Where the result is:
Genotypes:
Bb, 50% BB, 25% bb, 25%Phenotypes:
Brown feathers, 75% Red feathers, 25%.In this case, the probability of having brown or red feathers is 3:1.
What is an astronomical unit or AU?
A)
A unit of time equal to one light year or 6 trillion miles.
B)
A unit of distance equal to the average distance from Earth to the Suntor
93 million miles.
A unit of distance equal to the size of the Milky Way Galaxy or 100,000
light years across
D)
A unit of time that is equal to the amount of time it takes light to travel
from the Sun to Earth,
Answer:
B
Explanation:
The correct option should be B.
The Astronomical Unit, AU, is a measurement unit for length in general astronomy and represents the mean or the average distance of the sun from the earth.
Mathematically, in astronomy,
1 astronomical unit = 150,000,000 km
But then, 1 km = 0.621371 mile
Hence,
150,000,000 km = 150,000,000 x 0.621371 miles
≈93,000,000 miles
Therefore, 1 astronomical unit can also said to be approximately equal to 93,000,000 miles.
The correct option is B

What % of energy does plants receive from the sun
Answer:
Most solar energy occurs at wavelengths unsuitable for photosynthesis. Between 98 and 99 percent of solar energy reaching Earth is reflected from leaves and other surfaces and absorbed by other molecules, which convert it to heat. Thus, only 1 to 2 percent is available to be captured by plants.
Explanation:
Four substances are involved in both photosynthesis and cellular respiration. They are sugars, water, oxygen, and carbon dioxide. Describe what happens to these four substances during photosynthesis
Answer:
Explanation:
Photosynthesis is a light catalyzed chemical reaction that occurs in nature by all plants.
The process involves the reaction between carbon dioxide and water in the presence of sunlight.
This in turn produces glucose and oxygen gas.
The reaction expression is given as:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
So, food is produced at the end of the reaction in form of glucose. In terms of energy, light energy is transformed into chemical energy stored in glucose.

can you create a punnett square for this question?
Answer:
The correct answer is 50%.
Explanation:
In the given question, the table says that fruit color is determined by the incomplete dominance of allele R and R'. In the case of RR genotype the fruit color will be red and R'R' the food color will be yellow but in the heterozygous condition the color would be orange, so the cross between RR' and R'R' would be as follow:
Punnett square:
R R'
R' RR' R'R'
R' RR' R'R'
It is found by the given cross that the cross between RR' and R'R' would form two orange fruit plants out of four which is 50%

How do typical human body temperature and pH explain why lactase can work efficiently in the human body of most humans?
Answer:
Lactase requires 6 pH and 37 degree Celsius temperature.
Explanation:
Lactase can work efficiently in the human body of most humans because the pH and temperature of the body is favorable for the lactase to work. Lactase has a range of pH from 2 to 7 but work best at the pH 6 and at the temperature of 37 degree Celsius which is the human body temperature and pH so that's why the lactase can work efficiently and effectively in the human body.

Does the amount energy from food eaten by each organism equal the amount of energy used but each organism?
Answer:
Ecosystem follows the 10% law.
Explanation:
The amount of energy that is available in the ecosystem is equal and same is equally distributed. Plants use solar energy and convert it into usable energy for processing food and water in tissues and reproduction and root development. Later on when the plant dies or is eaten up the dead organic matter is converted to energy that is derived by the herbivorous or primary consumer. When then (90%) lost through respiration and digestion, waste generation in the body. After which the energy left may be again taken up by some secondary consumer and only 10% energy remains while the rest is diffused in the ecosystem and environment. Thus energy is neither created nor destroyed but transformed in its form.why is it beneficial for female peacocks to choose to mate with a male peacock with a full colorful trains?

The cell cycle begins again after
A. synthesis has copied each chromosome.
B. mitosis has formed two identical nuclei.
C. cytokinesis has formed two new cells.
D. differentiation has made cells specialized.
Answer:
C. cytokinesis has formed two new cells.
Explanation:
Cell cycle has different stages called G1, S, G2, and M. ... This is where the cell actually partitions the two copies of the genetic material into the two daughter cells. After M phase completes, cell division occurs and two cells are left, and the cell cycle can begin again.
If I have 8 DNA nucleotides, how many
DNA
bases do I have?
How many base pairs?
Answer:
Each nucleotide contains phosphate, sugar (of the deoxyribose type), and one of the four bases (Figure 8-4). When the phosphate group is not present, the base and the deoxyribose form a nucleoside rather than a nucleotide. The four bases are adenine, guanine, cytosine, and thymine.
