Answer:
The question is somehow not correct, it suppose to be what is the MASS of an object that needs a force 4500N to accelerate it at a rate of 5 m/s as gotten from another website.
The correct answer is 900kg.
Explanation:
To get the mass of the object use the formula
F=Ma
Where F is force
M is mass
a is acceleration.
F= 4500, M=? a=5m/s
4500= M× 5
M=4500/5
M=900kg
Mass is in kg
The presence of the minute growth near the disc signifies that the bacterial innoculum contains mutant microorganisms that are able to grow in the presence of toxic substances.
<h3>What are zones of inhibition?</h3>
The sensitivity testing in a microbiology laboratory is done to determine the effect of antibiotics on various bacteria organisms
The zone of inhibition when a disk method is used signifies the area of media where bacteria are unable to grow, due to presence of a drug that impedes their growth.
If there are presence of minute growth near the disc, it means that the bacterial innoculum contains mutant microorganisms that are able to grow in the presence of toxic substances such as disinfectants.
If these mutant bacteria organisms are not cleared by the disk method, it means that they cannot be killed by the disinfectant/antiseptics that is being tested.

Answer:
All the options are correct regarding hypothalamus.
Explanation:
The hypothalamus is the part of the forebrain. The diencephalon is divisible into 2 parts - thalamus and hypothalamus. It regulates various functions of the body.
This is the thermoregulatory center of the body. It gives the signal to sweat during a hot environment and shiver in winter. This maintains the water balance in the body by stimulating the secretion of ADH hormone in the kidney.
Hypothalamus also has regulated anterior pituitary hormone secretion. Thus it controls the endocrine secretion of pituitary glands.
This plays an important role in hunger and thirst. The feeding habits like the licking of lips, swallowing, and salivating by seeing delicious foods is due to hypothalamic activities.
The behavioral activities of individuals influenced by the hypothalamus. It is worked along with the limbic system of the brain. The behavioral activities include fear, punishment and sexual desire.
The reason for the loss of color after the industrial revolution is that the light-colored moths were "selected against" by predators. These birds could only see the light ones against the newly dark, sooted background. Over time, these predators could no longer distinguish the dark ones from their natural dark, sooted background. Thus more light-colored moths stood out against the dark soot, and were eaten. And more dark-colored moths eluded the birds, survived to reproduce, passing on more of their dominant genes for dark color to their offspring. After several decades of hundreds of thousands of generations, most of the later generations were dark, due to selective advantage of camouflage to survive predation.
