The answer is below
Explanation:
There are different types of biological tools, with each of them having different functions. However, for the sake of the question, some of the popular tools will be listed here.
1. Stockroom tools: this includes:
Beaker: this is essential to take or storing small substances
Bunsen Burner: this is important in the biological lab to heat a substance
Flask: this is essential in holding liquid substance.
Pipette: it forms of a lab spoon that is used in mixing substances to form a compound or mixture
2. Computer and Imaging system: this is important in image analysis and sequence-analysis programs
3. Cell cultures: this is used in the biological lab to enhance the complex cell differentiation required in the experimentation of animal cell structure
4. Microscopes: this is essential in determining and examining the microscopic organism that we can not see with our makes eyes
I believe the answer is...a change in allele frequency over many generations!
Hope this helps!
Answer:
sugar molecule
Explanation:
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.
Answer:
The correct answer would be : option E.
Explanation:
Sphinx moth Xanthopan morganai is montypic genus of sphinx moth which has only one species which gives it as a name of morgan's sphinx moth found in east Africa and Madagascar.
This species of moth have a 8 inch long tongue which is characteristic feature of the species. The 8 inch long tongue gives them advantage in reaching to the nectar where no other pollinator can reach to their.
Thus, The correct answer would be : option E.
Answer:
Adrenal medulla
Explanation:
Fight-or-flight or acute stress response is marked by physical changes, including nervous and endocrine changes, that prepare human or an animal to react or retreat. This response was first discovered by an American Physiologist, Walter Bradford Cannon.
In response to an acute stress, an area of the brain called AMYGDALA sends an emergency signal to the HYPOTHALAMUS, which acts like a command center and activates the body's sympathetic nervous system by releasing hormones. The sympathetic nervous system stimulate the adrenal medulla gland, triggering the release of CATECHOLAMINES (Epinephrine/adrenaline and Norepinephrine/noradrenaline) into the bloodstream.
This release induces several physiological changes in the body; The heart beats faster than normal; pushing blood to the muscles, heart and the vital organs, increased in blood pressure, blood sugar (glucose) are released into the bloodstream to give us the extra energy we need.
