What environmental conditions can influence heredity?
everything in the environment essential for sustaining life and the capacity to alter one's DNA like the UV rays
What does it mean when you say an organism is pleomorphic?
is the ability of some bacteria to alter their shape or size in response to environmental conditions
What three things can alter the rate of an enzyme?
Three things that can alter the rate of an enzyme are; temperature, pH and substrate concentration. Enzymes will have an optimal temperature and pH, at which they will have the greatest rate. Below or above these optimum conditions, the rate will be slower.
Why do you think chemistry will not change the decay rate of an isotope?
It depends what is meant by 'decay'. It will not alter the atomic decay rate but elements can be chemically affected by the environment which can chemically decay them.
How do internal temperature or pH changes disrupt the homeostasis of an organism?
Internal temperature or pH changes can disrupt the homeostasis of an organism by affecting the functioning of enzymes and proteins, which are sensitive to changes in their environment. These changes can alter the rate of biochemical reactions and disrupt the overall balance within the organism. Organisms have mechanisms in place, such as sweating or shivering in response to temperature changes, or buffering systems to maintain stable pH levels, to regulate these variables and restore homeostasis.
What are the component parts of a homeostatic mechanism?
Homeostatic mechanisms share the following three components:Receptors - provide information about specific conditions (stimuli) in the internal environment.Set points - tell what a particular value should be.Effectors - cause responses that alter conditions in the internal environment.
What environmental conditions can influence heredity?
everything in the environment essential for sustaining life and the capacity to alter one's DNA like the UV rays
Which statement explains the importance of maintaining a constant internal environment to ensure proper enzyme functioning?
Increasing the temperature and pH can alter the specific shape of enzymes.
What is the definition adaptation?
An inherited characteristic that allows an organism to survive in a particular environmentAn adaptation is a positive characteristic of an organismthat has been favoured by natural selection
Can injury to the spinal cord alter a person's internal temperature?
Yes
Is it true that only humans have the capacity to alter the environment at will?
Yes, Only people have the capacity to alter the environment at will. Only people have minds to develop Intelligent approaches to environmental problems.
How did the Chavin and the Moche alter their environment?
The Villagers Had to Pay the Taxes to their Emperor's! Order to keep their environment!
Both the internal and external environments can modify or alter a gene yes or no?
False.
Why did the author indicate that your very earliest ancestors did not appreciably alter their environment because they?
Because at that point in their evolution they were just an integral part of their environment, that is to say that that their environment assimilated them. Also at that point in their evolution they did not possess sufficient technology to drastically alter their environment, unlike today, where the role has been reversed and we have assimilated the environment.
What has the ability to alter DNA?
The environment, viruses, and scientists have the ability to alter DNA. These alterations may potentially be passed on to future generations.
What weathering alter the internal structure of minerals by removing and or adding elements?
Chemical weathering
How can a stressful environment alter the standard r-selection and k-selection?
1. What is the difference between r-selected and k-selected organism? Which strategy would you expect to be more prevalent in unpredictable environments (high stochastic variation in conditions)?
