Noting the color of a solution as it is heated.
Answer:
o%
Explanation:
If white and red roses are incompletely dominant, the phenotypes are as following:
AA - red roses
AB - pink roses
BB - white roses
So, a cross between a red (AA) and a pink rose (AB) will result in only red or pink roses:
Parents: AA x AB
Offspring: AA AA AB AB
Carbon is important in biology molecules because of its unique chemical properties. It can form stable covalent bonds and is the basis of organic compounds. Carbohydrates, lipids, proteins, and nucleic acids, all essential for biological processes, contain carbon.
Carbon is extremely important in biology molecules due to its unique chemical properties. Carbon atoms have four valence electrons, allowing them to form stable covalent bonds with other atoms, including other carbon atoms. This ability to form a wide variety of molecular structures makes carbon the basis of organic compounds, which are the building blocks of life. For example, carbohydrates, lipids, proteins, and nucleic acids, which are essential for various biological processes, all contain carbon.

Carbon's unique ability to form up to four covalent bonds with other atoms including carbon itself allows it to serve as the 'backbone' of most biological molecules. It forms complex structures that explain the diversity in molecular forms and functions. Its abundance and vital role in cellular function and across ecosystems make carbon fundamental to biology.
Carbon is exceedingly important in biological molecules because of its unique bonding properties. With four valence electrons, carbon has the capacity to form covalent bonds with other carbon atoms or various elements like oxygen, nitrogen, and hydrogen. This allows carbon to act as the fundamental building block, or 'backbone', of macromolecules such as proteins, carbohydrates, nucleic acids (RNA and DNA), and lipids, which are vital for life.
All living organisms are carbon-based, emphasizing its importance in biology. Carbon can form long and branching chains, enabling the creation of more complex structures. These chains can bond with other elements to allow for a wide variety of molecular forms, which results in diverse functionality. This characteristic of carbon bonding, and its vital role in the cell composition, constitutes carbon's significance in biology.
Indeed, the carbon cycle exemplifies the interconnectedness between living organisms across different ecosystems. Hence, given its central role in the structure and function of macromolecules, it could indeed be said that carbon is the 'foundation' element for molecules in living things.

D. the parotid glands
Answer: True
Humans have impacted the rainforests through mining, agriculture and construction as rainforests are mainly occupied with large forests trees and vegetation. Human clear cut the forests to make the land available for the purpose of mining to derive economically valuable minerals from earth, construction of house and for agriculture. This has resulted in the extinction of large number of floral and faunal species from earth. It has decreased the percentage of forest cover on earth.
According to the question, it is true that Humans have impacted the rainforests through mining, agriculture, and construction.
How human impacted the rainforests through mining
Gemstones and Precious metals such as gold, copper, diamond are important resources that can be found in the rainforests across the world. Extracting these resources is harmful activities that contribute lot of damages to the rainforests ecosystem. It causes problem for the people that live close to the rainforests. Chemical pollution and deforestation from mining can have a great adverse effect on the rainforests environment. It also affects downstream aquatic habit.
How human impacted the rainforests through Agriculture
In the rainforests, large areas are cleared for pastoral farming because the demand of meat globally has increased the opening of cattle farms in the rainforests and this also cause deforestation which has adverse effect on the rainforests. Arable farming also contribute to the loss of tropical rainforests as many farmers are clearing the land to grow crops such as soya beans.
How human impacted the rainforests through Constructions
Road building has different of direct impacts on the rainforests. In most wet tropical rainforest, the cut and fill operation related with road construction can prevent easy flow of streams, increase flooding in the forest and can drastically increases erosion in rainforests. Construction of roads in the rainforest can discharge nutrients and chemical pollutant into water ways and create avenue of invasion for disturbing exotic species.

KEYWORDS:
Test cross is the cross between an organism with unknown dominant genotype and an organism with known recessive genotype.
Since dominant trait results from a dominant allele, the test cross can determine if an unknown genotype is heterozygous and homozygous dominant.
If A is dominant allele, and a is recessive allele, then AA is dominant homozygote, Aa is a heterozygote, and aa is recessive homozygote.
According to the Punnett square, if all of the offspring are heterozygote (Aa), then unknown genotype is dominant homozygous (AA). If half of the offspring are the heterozygote, and the other half are recessive homozygote, then the unknown genotype is heterozygote (Aa).
Answer:
Conduct a test cross with a purebred recessive plant.
Explanation:
Verified after test was graded within ody ssey ware system as question # 10.
The questions wording: You have a plant with yellow seeds, which express a dominant phenotype. How would you determine the plant's genotype?
atmosphere
water table
respiration of animals
The answer is that it gets nitrogen from the soil.
