7 m/s
Explanation:
Acceleration,
Where v and u are the final and initial velocities of the Justine respectively, t is the time taken for Justin to attain final velocity.
Making v the subject then
v=at+u
Taking u as zero then
Substituting 3.5 for t, 2 as a then
v=3.5*2=7 m/s
the nostrils catch the big dust particles while the small and escaped dust particles from nostrils stick to the mucous
Explanation:
It should be noted that the vegetables at a buffet should be heated to a temperature of about 140°F or above. This is necessary in order to prevent the food from spoiling which is referred to as the temperature danger zone which is when the temperature is lesser and this can result into bacteria growing on the food.
Answer:
Heterozygous
Explanation:
Heterozygous Is when an organism has two identical alleles for a trait. TT or tt. RR or rr
The influx of positive charges makes the membrane potential more positive and is known as depolarization.
<h3>
What makes the membrane more positive charge ?</h3>
The membrane potential normally becomes more positive in response to neurotransmitters that open Na+ channels, more negatively in response to those that open K+ channels, and vice versa in response to neurotransmitters that inhibit these channels.
<h3>What does polarization mean?</h3>
The orientation dispersion of the electromagnetic waves that make up light beams is referred to as polarization. Unpolarized (uniformly mixed orientations), linearly polarized (fixed orientations), and circularly polarized are some of the different polarization states that light can take on (rotating field about the line of sight).
<h3>How membrane is affected by polarization and depolarization?</h3>
At a specific location on the neuron's membrane, hyperpolarization occurs when the membrane potential increases, and depolarization occurs when the membrane potential decreases (more positive).
