Answer:
b. di uses across a synaptic cleft from a neuron to a muscle cell.
Explanation:
A neurotransmitter is di uses across a synaptic cleft from a neuron to a muscle cell. Neurotransmitters are chemicals which enable neurotransmission. In reaction to an impulse a motor neuron axon secretes a neurotransmitter and causes the muscle fiber to contract. It is a chemical messenger which passes on the signals across the chemical synapse.
Eutrophication is the overgrowth of algae in lakes and ponds
that is usually caused by the introduction of different chemicals
into the water from fertilizer run-off. Some ways to combat this
are to increase the flow of moving water, prevent contamination
from fertilizer, and reduce pollution of our lakes and streams.
Answer:
<em>Nitrogen</em><em> </em><em>dioxide</em><em> </em><em>is </em><em>an </em><em>irritant </em><em>gas,</em><em> </em><em>which </em><em>at </em><em>high </em><em>concentration</em><em> </em><em>cause </em><em>inflammation </em><em>of </em><em>the </em><em>airways.</em><em> </em><em>.</em><em>.</em><em>.</em><em> </em><em>Nox </em><em>gases </em><em>react</em><em> </em><em>to </em><em>form </em><em>smog </em><em>and </em><em>acid </em><em>rain </em><em>as </em><em>well </em><em>as </em><em>being </em><em>central </em><em>to </em><em>the </em><em>formation</em><em> </em><em>of </em><em>fine </em><em>particles </em><em>and </em><em>ground</em><em> </em><em>level </em><em>ozone,</em><em> </em><em>both </em><em>of </em><em>which</em><em> </em><em>are</em><em> </em><em>associated</em><em> </em><em>with </em><em>adverse </em><em>health</em><em> </em><em>effects.</em>
Answer:
9/16 Kinked tail, normal growth
3/16 Kinked tail, obese growth
3/16 normal tail, normal growth
1/16 normal tail, obese growth
Explanation:
Kinked tail (K) is dominant over normal tail (k) and normal growth (N) is dominant over obese growth (n). Two mice that are heterozygous for both traits (KkNn) are crossed:
KkNn x KkNn
offspring:
<em>9/16</em><em> K_N_ - Kinked tail, normal growth</em>
<em>3/16</em><em> K_nn - Kinked tail, obese growth</em>
<em>3/16</em><em> kkN_ - normal tail, normal growth</em>
<em>1/16</em><em> kknn - normal tail, obese growth</em>

An ecosystem is a geographic area where plants, animals, and the other organisms work for the existence of bubble life.
<h3>
Variation of ecological habitats within a species is characteristic of which type of diversity?</h3>
The variation of ecological habitats within a specie is character of the type of diversity is known as Ecosystem Diversity.
Ecosystem is defined as the different kinds of habitats, ecological processes and communities. A biological community is defined by the specie which occupy a specific area and the interactions between the species.
So we can conclude that: An ecosystem is a geographic area where plants, animals, and the other organisms work for the existence of bubble life.
