An experimental cross where only a single characteristic is considered (for example, flower color) is called ______. Multiple choice question.
An experimental cross where only a single character is considered (for example, flower color) is called monohybrid.
What is a monohybrid cross?A monohybrid cross is a type of genetic cross where only one phenotypic trait is assessed in the offspring.
This phenotypic trait can be any observable feature of the individual (for example, flower color in plants).
The monohybrid cross is very useful to understand the inheritance pattern of a particular trait.

Describe how a decrease in ocean ph can affect marine organisms.
Ocean acidification can negatively affect marine life, causing organisms shells and skeletons made from calcium carbonate to dissolve. The more acidic the ocean is, the faster the shells dissolve.
Hope this helps :))
Organisms depend on pH for living in aquatic life, because due to acidification carbonate is lost, which is the main basic ingredient of saltwater.
How ocean pH affects marine organisms?Carbonate, a main basic ingredient of salt water, is lost as a result of ocean acidification. This makes it more challenging for marine organisms to develop shells and skeletons.
Ocean acidification is sometimes called to as "sea osteoporosis" with a great cause. Ocean acidification can dissolve the minerals used by oysters, clams, lobsters, shrimp, coral reefs, and other sea animals to create their shells and skeletons.
Human health is also an issue, when the acidity of the water increases, the mucus on fish gills hardens, limiting the quantity of oxygen that may enter. This is why pH changes regularly result in fish deaths.
Therefore loss of carbonate from the ocean, the pH of the ocean affects the marine organisms.

Leia is crossing sunflowers that have different genotypes for height. She crosses a tall sunflower plant with a genotype of tt with a short sunflower plant with a genotype of tt. Which ratio shows the probability that the two sunflower plants will produce a sunflower plant with a genotype of tt?.
25:25 ratio shows the probability that the two sunflower plants will produce a sunflower plant with a genotype of tt.
What do you mean by genotype?The genotype of an organism is its complete set of genetic material. Genotype can also be used to refer to the alleles or variants an individual carries in a particular gene or genetic location.
A genotype is a scoring of the type of variant present at a given location (i.e., a locus) in the genome. It can be represented by symbols. For example, BB, Bb, bb could be used to represent a given variant in a gene.
A genotype is the specific DNA that an organism inherits from its parents. A phenotype represents every possible way that the genotype manifests itself in the organism.

O A government sells a section of prairie to a private company interested in drilling for oil.
A rancher cuts down several trees on her property to get wood to use to repair a fence.
A national forest suffers from erosion due to the use of all-terrain vehicles.
Answer:
Likely the government selling off the prairie
Explanation:
Everyone is losing out on the prairie getting sold to a private corporation, hence why this is the tragedy of the commons
The scenario in which the land is most likely to be degraded as a result of the "tragedy of the commons" is a national forest that suffers from erosion due to the use of all-terrain vehicles. Thus, the correct option for this question is D.
What is land degradation?Land degradation may be defined as the process through which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land. All these influences gradually reduce or lose the biological or economic productivity and complexity of rain.
A national forest that suffers from erosion due to the corresponding utilization of all-terrain vehicles ruptures the soil productivity due to erosion. This finally leads to the degradation of land with respect to the "tragedy of the commons".
Therefore, the correct option for this question is D.

How does the law of conservation of mass apply to earth’s recycling of water, oxygen, carbon, and nitrogen. Give one example
Answer:
The law of conservation of mass states no matter is created or destroyed. This means that the matter currently on Earth is the only matter that will ever be available to us. However, it also means that this matter will not be destroyed. So, water, oxygen, carbon, and nitrogen are all used by living things in our world and then recycled to be used again.
One example of this is the water cycle. More water is never added or taken from the world, it is just reused. First, water starts in some body of water and then evaporates into the air. Then, the water falls back to Earth as precipitation.
