Answer:
A reversible reaction is a chemical reaction where the reactants form products and products react together with reactants to give the reactants back. When they yield the same amount, Reversible reactions will reach a chemical equilibrium in which the concentrations of reactants and products will no longer change.

Imagine you are producing a short film depicting the molecules and biological processes involved in gene expression. For this, you need to first create a storyboard for your film. A storyboard is a sequence of drawings, along with some description or dialogue, that illustrates and represents the scenes of a story or movie. Create a storyboard for the process of gene expression/central dogma depicting the story of how the cell uses the information in DNA to synthesize a protein.
Answer:
By decoding information with the help of transfer RNA (tRNA).
Explanation:
The cell uses the information in DNA with the help of transfer RNA (tRNA) to synthesize a protein because transfer RNA (tRNA) decode a messenger RNA (mRNA) in order to produce proteins according to the information present in messenger RNA (mRNA). The information about protein is stored in a gene's DNA which is passed to a RNA in the cell nucleus which is responsible for formation of copies of DNA in the process of translation. So the cell uses the information of gene's DNA with the help of RNA molecules.
As the Earth's climate continues to get warmer, air quality is expected to get worse (e.g., ozone level and particulate matter).

In North America, the eastern spotted skunk mates
in late winter, and the western spotted skunk mates
in late summer. Even though their geographic
ranges overlap, the species do not mate with each
other. What most likely prevents these two species
from interbreeding?
A. habitat isolation
B. gametic isolation
C. geographic isolation
D. reproductive isolation
Reproductive isolation is a mechanism through which species do not get to interbreed. Option D. reproductive isolation
What is reproductive isolation?This is a mechanism through which different species or populations do get to mate and produce fertile offspring. This mechanism allows the accumulation of genetic differences and favors speciation.
There are different barriers that inhibit or interrupt the genetic flow between different species.
Reproductive barriers prevent mating between two or more species. There are two types of barriers,
prezygotic ⇒ that avoids fertilization between individuals of different species, postzygotic ⇒ that impedes the zygote to develope and reach the adult stage.Pre-copulatory o pre-ziygotic:
• Ecological or by habitat isolation;
• Seasonal or temporal;
• Séxual o ethologic;
• Mechanic;
• Gametes incompatibility.
Postzygotic mechanisms or barriers include
• Hybrid inviability,
• Hybrid sterility,
• Cytoplasmic interactions.
In the exposed example occurs a seasonal difference between the mating period of the eastern spotted skunk and the western spotted skunk.
Probably, if both of them would mate during the same season and in the same area, they could reproduce.
However, since their mating season differs, individuals from each species do not get to cross and hence, produce fertile offspring.
Option D. reproductive isolation is what most likely prevents these two species from interbreeding

Explanation:
Jaguars are a keystone species in the Amazon. Describe how they can be so essential to the ecosystem despite
being significantly less abundant than many other species.
Answer:
jaguars are keystone species because they feed herbivorous species that might decimate the plants of the ecosystem
Explanation:
Keynote species are species that help to maintain the homeostasis of the ecosystem so if they lack then the ecosystem would change drastically. Moreover, a top predator is a predator that occupies the highest trophic level in the food chain. Jaguars are both keystone species and top predators that feed herbivorous species, maintaining the health of the food chain by eliminating the excess of primary consumers that otherwise would feed too many plants (i.e., primary producers) which produce and store energy at the bottom of the food chain.

A farming consortium is experiencing serious problems establishing stable and profitable rice production in their Northern California acreage. It is unclear whether the problem is the strain of rice being used, or a range of local environmental issues, including local pests and local soil conditions. Which of the following plant professionals is the company most likely to choose to address this problem?
Answer:
A way that plant professionails can address and fix the problem is by introducing the idea of GMOs and genetically modifying the rice. This would make rice be able to grow in harsh conditions and become sustainable to pests. Also, genetically modified rice is cheaper and will bring in more money.

Which consequence is a direct result of human population growth
Answer:
One of the largest environmental effects of human population growth is the problem of Global warming.
Economic development, urbanization, energy consumption, transportation/motorization due to rapid population growth are major driving forces of air pollution in large cities.
In order to support the growing population, forests are being destroyed at an alarming rate. Deforestation occurs when humans clear forests to use the land either for agriculture or for habitation. This leads to soil erosion and the extinction of plant species. Land animals also decline in numbers and even face extinction due to human expansion that encroaches on their natural habitat and limits their ability to spread geographically.
Humans also continue to put a great demand on the natural resources of our planet. Many non-renewable resources are being depleted due to the unrestrained use of fuel and energy. Many parts of the world also suffer from a shortage of food and water.
The growth of the population puts larger demands on our already limited resources. The environment on earth is suffering from the growth of the global population. The depletion of resources and biodiversity, the production of waste, and the destroying of natural habitat are serious problems.

Which of the following represents an agricultural factor greatly decreasing the availability of crops?
Answer:
Climate.
Explanation:
Climate is the factor which is responsible for the decreasing the availability of crops because climate is the factor that allows crops to grow in the region. Suitable climatic conditions allows us to grow more plants in the region while on the other hand, less or no crops can be cultivated in the harsh climatic conditions. The plants in the harsh climatic condition are unable to grow such as desert where the temperature is very high and no rainfall occurs to support growing of crops.
