Describe the effect on an enzyme of an increase in environmental temperature above the optimum temperature range of the enzyme.
Answer:
In an environmental temperature above optimum temperature will cause the enyzmes to denature (deform), because when they denature the subtrate will no longer fit into the enzyme
The effect on an enzyme of an increase in environmental temperature above the optimum temperature range of the enzyme - denature the enzyme and lose the specific shape of the enzyme leads to losing its activity.
An enzyme is a substance that acts as a catalyst in living organisms, regulating the rate at which chemical reactions proceed without itself being altered in the process
Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction.extremely high temperatures above the optimum temperature can cause an enzyme to lose its shape (denature) and stop workingThus, the effect on an enzyme of an increase in environmental temperature above the optimum temperature range of the enzyme - denature the enzyme and lose the specific shape of the enzyme leads to losing its activity.

offspring.
Answer: During gamete formation, the alleles for each gene segregate from each other, so that each gamete carries only one allele for each gene. an individual gene may code for a specific physical trait, that gene can exist in different forms, or alleles.
What are genes?
Genes are an basic physical and functional unit of heredity.Genes are what make our DNA.

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?
Species brought in by the storm surge will displace species native to the coastal wetlands.
Species reliant on coastal wetlands for survival may experience a decline in population due to loss of
habitat.
Coastal wetlands will grow exponentially with the input of nutrients from storm upwelling and biodiversity
will increase in these areas.
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
Answer:
Species reliant on coastal wetlands for survival may experience a decline in population due to loss of
habitat.

The main characteristics of the bacteria domain is that they lack a well-defined nucleus and are known as prokaryotes.
What is the main characteristic of the bacteria domain?All living things are classified into kingdoms based on specific characteristics found in organisms in that kingdom.
For the bacteria kingdom, the main characteristic present is that they lack a well defined nucleus as well as nuclear membrane.
Organisms without a well-defined nucleus are known as prokaryoytes.
Thus, the main characteristics of the bacteria domain is that they lack a well-defined nucleus and are known as prokaryotes.

natural selection is an example of a mechanism of evolution. does this mechanism produce a change in individuals or population? explain
Natural selection refers to the procedure where the species better amended to their surrounding appear to survive and generate more offspring. Natural selection refers to one of the mechanisms that make modifications in the frequencies of genes in populations and thus, it is the mechanism of evolutionary change.
However, the phenomenon of genetic drift and natural selection cannot take place unless and until there is a genetic variation, that is unless some individuals are genetically distinct from others.
