This type of movement of the unicellular organisms is called twitching motility.
A small filament on the top of the bacterial cell enables the bacteria to move in this fashion.
Twitching motility is key to pathogenesis and forming biofilm in bacteria.
Asexual reproduction produces genetically identical offspring and sexual reproduction creates variation in the offspring. When the environment changes and it affects the asexual offspring it will affect all identical copies whereas since the sexual offspring have more variation, they are more likely to survive.
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.
Answer:
The monkey is a new world monkey
Explanation:
The New world monkey is the monkeys which are evolved from the old world monkey-like apes and many other genera.
These monkeys have evolved from the old world Simian monkeys in South America about 40 million years ago and adapted to survive in the tropical areas of South America and the regions of Mexico.
This monkey can be characterized by their long-tails called prehensile tails, the use of their hands and feet to walk on the trees.
Since the characters of the monkeys provided in the question show similar characteristics to these, therefore, are considered the New World Monkeys.
