What else can I help you with?
Is natural selection the only force that drives biological evolution?
No. Natural selection requires reproductive variation to work on. Besides reproductive variation and natural selection, there are various forces, biochemical as well as population dynamical, that affect the allelic composition of a population.
What theme unifies all of biology?
The theme that unifies all of biology is the concept of evolution. Evolution by natural selection drives the diversity of life on Earth, explaining how organisms adapt to their environments over time. All biological processes, from cellular functions to ecosystems, can be understood through the lens of evolution.
Why cannot human be immortal?
The aging process, DNA damage, and cellular senescence all contribute to the limitations of human lifespan. Additionally, environmental factors, diseases, and accidents can impact human mortality. Biological immortality would require overcoming these factors, which present significant challenges.
Biological changes lifestyle interactions with people and the demands of school or work can all contribute to stress?
Biological changes such as hormonal fluctuations can impact stress levels. Lifestyle factors like poor sleep or lack of exercise can also contribute to stress. Interactions with people, such as conflicts or lack of support, can further exacerbate stress, as can high demands in school or work environments.
What proof do we have evolution taking place?
Evidence for evolution includes the fossil record, comparative anatomy, molecular biology, and observed instances of natural selection. These different lines of evidence all support the concept of biological evolution occurring over time.
What is biopsychosocial approah?
A biopsychosocial approach assumes that biological and psychological factors like thoughts, emotions, and behaviors, and other social factors, all contribute to human wellbeing and illness.
What does evolution unify?
All of the biological sciences. The theory of evolution by natural selection is the backbone of biology.
What biological molecules that are considered evidence for evolution include?
Biological molecules are considered evidence for evolution include a. DNA b. amino acids c. porteins d. all of the above Answer: D. All of the above

What was required for the progression from chemical evolution to biological evolution?
Actually, biological evolution was never proven, though still taught in schools as a fact. Thousands, if not millions of different chemicals had to have been there all at the same exact time, with the perfect timing and arrangement for even a single-cell organism to be created. The probability of all of those factors to be perfectly arranged and mixed together is 101,000,000,000 or 10 to the power of 1 billion. 102 is only a 1% chance anyway, so 101,000,000,000 is literally next to impossible.
What factors contribute to or influence history?
Geography, Religion and People all contribute to or influence history.

The theme that unifies all of biology is the concept of evolution. Evolution by natural selection drives the diversity of life on Earth, explaining how organisms adapt to their environments over time. All biological processes, from cellular functions to ecosystems, can be understood through the lens of evolution.
Which biological factors do you think are the most important at each stage of development?
All of them.
Biological factors that affect an organism's niche include all what except what?
Biological factors that affect an organism's niche include its diet, predators, competitors, and physical attributes. Non-biological factors that can also affect an organism's niche include abiotic factors such as temperature, habitat structure, and availability of resources.
What is the relationship between all factors?
the relationship between mental illness and biological processes, conditioning, gender and social factors.
