Option D
polymerase chain reaction (PCR) do Makes more copies of a sample of DNA
<u>Explanation:</u>
A procedure to create several portraits of a distinct DNA section is termed as Polymerase chain reaction. In other words, it is a lab routine handled to compose various representations of a portion of DNA. PCR is extremely explicit and can be utilized to increase, or model, a particular DNA destination from a hybrid of DNA particles.
In PCR, the effect is regularly cycled within a range of temperature variations, which deduct countless models of the destination range to be exhibited. PCR intends to obtain sufficient of the objective DNA region that it can be examined or applied in some other way.
Answer:the part of the brain that has most likely been damaged in this experiment is the suprachiasmatic nucleus (SCN) found in the hypothalamus of the brain.
Explanation:
circadian rhythms are behavioural changes that respond to light and darkness in an organisms environment. The sleep-inducing wake cycle is a good example of a circadian rhythm. In the experiment, the disruption of the mouse SCN led to development of imbalances in the circadian rhythm of sleep and wake cycle leading to falling asleep and waking up at random times of the day and night. I hope this helps. Thanks
The following five limiting factors would control the
population density of weeds;
<span>1.
</span>Supply and nutrients in the soil
<span>2.
</span>Presence/Absence of growth-restricting
substances such as pesticides
<span>3.
</span>The soil aeration and soil structure
<span>4.
</span>Moisture content in the soil.
<span>5.
</span>Biotic factors such as disease and pests
<span>6.
</span>Quality, intensity and duration of light
Physical weathering because it affects the appearance by breaking down the rock instead of changing its chemical interior
Answer:
there are 12 marbles. the probability of getting a yellow would be 2/12, the probability of drawing a red is 4/12, and the probability of getting a black is 3/12. (i think,, dont quote me if im wrong!)
