what determines the function of a protein
Answer:
The sequence of amino acids. - The three-dimensional shape of the folded protein. - If the coding sequence has a mutation that leads to a change in the amino acid sequence, the protein may have a different three-dimensional shape, reducing its activity.

is a rotting log considered living or non living? why?
Answer:
A rotting log is nonliving. However, it can have mold, lichen, or fungus growing on it, which is not the log itself. Those three things are living. And though the log was once a living tree, at it's current state, it is nonliving.

How are gross production and net production different?
a. Net production is always greater than gross production.
b. Net production is always less than gross production.
C. Only animals have net production.
d. Only plants have net production.
Please select the best answer from the choices provided
Ο Α
OB
ОС
OD
Answer:
b. Net production is always less than gross production.
Explanation:
The main production i.e. done in ecology would do the production in the organic compounds with the help of photosynthesis. The gross production is the value i.e. generation of organic compounds by producers while the net production is the value of organic compounds i.e stored by producers. It should be lower than the gross production as the plants are not able to store large number of organic compounds than they generated
A hurricane passes through the Gulf of Mexico and destroys many of the coastal regions of Northwest Florida. Which of the following is a likely impact of this catastrophic event on biodiversity?
Group of answer choices
Species brought in by the storm surge will displace species native to the coastal wetlands.
Excessive salt from the storm surge will flood coastal wetlands and raise salinity to intolerant levels for the local species, causing a decrease in biodiversity
Coastal wetlands will grow exponentially with the input of nutrients from storm upwelling and biodiversity will increase in these areas.
Species reliant on coastal wetlands for survival may experience a decline in population due to loss of habitat.
Answer:
Species reliant on coastal wetlands for survival may experience a decline in population due to loss of habitat.
Explanation:
A hurricane destroys many coastal regions of Northwest Florida which leads to the loss of habitat of many species that lives on the coastal region of Northwest Florida. This hurricane destroy the habitat that leads to decrease in population of organisms that lives in that coastal region so we can conclude that the population of organisms decreases due to this hurricane.

what type of mutation has the least amount of impact on a protein ?
Answer: Silent Mutation
Explanation: Silent mutation: Some mutations that change DNA bases do not have any effect on the sequence of amino acids in the protein. These mutations are called silent mutations and they do not affect the structure or function of the protein because there is no effect on the amino acid sequence.
Answer:
Point Mutations
Explanation:
It is the least harmful mutation

Which of the following best describes the genes of offspring of organisms that reproduce sexually?
Answer:
Each of the offspring is genetically unique and received some of its genetic
Explanation:
While reproducing sexually, The zygote receives half of the gametes of male organism while half of the gametes of female organism. This constitutes to the total number i.e. 46 chromosomes.
While the zygote receive half from male and half from female, This means that the offspring produced by the zygote will have both the characteristics in common of the male as well as female. Remember that, Chromosomes contain gene which are particularly responsible for characteristics.
So, Each of the offspring is genetically unique and received some of its genetic information from each parent, so each has some traits in common with each parent.
How does soil composition affect the number and types of organisms an environment can support?
(Biome majors)
Answer:
The number of organisms an ecosystem can support depends on the resources available and abiotic factors, such as quantity of light and water, range of temperatures, and soil composition. Given adequate biotic and abiotic resources and no disease or predators, populations (including humans) increase at rapid rates.
why does deforestation occur
Answer: deforestation occurs because we need wood for our different uses, hence we cut down trees for them.Examples of uses-making wooden furniture, finding place for new infrastructures etc.
explain why biodiversity in an ecosystem is important?
Answer:
It is important because we need many different types of animals. Food chains are made up of many different links, and if there are fewer links, this will lead to animals not being able to feed. Biodiversity boosts the ecosystem and leads to an ecosystem that is self sustaining and able to produce things for people.

What's a node on a cladogram?
Answer:
The node therefore represents the end of the ancestral taxon and the stems , the species that split from the ancestor. The two taxa that split from the node are called sister taxa.
Explanation:
Answer:
A n0de corresponds to a hypothetical ancestor. A terminal node is the hypothetical last common ancestral interbreeding population of the taxon labeled at a tip of the cladogram. ... Each internal n0de is also at the base of a clade, which includes the common ancestral population (node) plus all its

how does water move through the water cycle
Answer:
The water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere, by the physical processes of evaporation, condensation, precipitation, infiltration, surface runoff, and subsurface flow. In doing so, the water goes through different forms: liquid, solid (ice) and vapor.

What causes cells in living organisms to be different from one another?
O A An organism evolves new cell types in response to its environment
O B. The brain of an organism sends a signal to its cells to differentiate when the organismis in danger.
O c The DNA of an organism moves from one cell to another, allowing different cells to have different functions
O D. An organism expresses different genes at different times in development, causing cells to be specialized
Explanation:
The cell types in a multicellular organism become different from one another because they synthesize and accumulate different sets of RNA and protein molecules. They generally do this without altering the sequence of their DNA.
How does air flow when a low-pressure center occurs in the atmosphere?
Answer:
A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation.
Explanation:
1. The pollutants in our atmosphere have the ability to change the entire planet’s
2. is a theory that states that the increasing carbon dioxide in the atmosphere is causing the climate to warm up.
Answer:
Ans1 Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn't exist on our planet's surface. And it warms our planet and keeps temperatures habitable for our living Earth
Ans.2 The carbon dioxide theory states that, as the amount of carbon dioxide increases, the atmosphere becomes opaque over a larger frequency interval; the outgoing radiation is trapped more effectively near the Earth's surface and the temperature rises.
