Gravity , Explosion
<u>Explanation:</u>
Nebulae are made of dust and gases—mostly hydrogen and helium. The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger.
Eventually, the clump of dust and gas gets so big that it collapses from its own gravity. The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star.
Answer:
d.0.48
Explanation:
When a population is in Hardy Weinberg equilibrium the <u>genotypic </u>frequencies are:
freq (AA) = p²
freq (Aa) = 2pq
freq (aa) = q²
<em>p</em> is the frequency of the dominant <em>A</em> allele and <em>q</em> is the frequency of the recessive <em>a</em> allele.
In this population of 100 individuals, 84 martians have the dominant phenotype and 16 have the recessive phenotype.
Therefore:
q²=16/100
q² = 0.16
q=√0.16
q = 0.4
And p+q=1, so:
p = 1 - q
p = 1-0.4
p = 0.6
The frequency of heterozygotes is:
freq (Aa) = 2pq = 2 × 0.4 × 0.6
freq (Aa) = 0.48
The answer is A. it belongs to a different family.
It can't be B because all the plants have different species.
It can't be C because not all plants listed are cherry trees.
Hope this helps :)
It is for the cells to make protein.
Answer:
In a simple synapse, neurotransmitter chemicals are received by the postsynaptic neuron.
Explanation:
The presynaptic membrane is where neurotransmitters are generated, whereas the postsynaptic membrane is where the neurotransmitter receptors have been located. The axon terminal is substantially far more structurally complicated at a neuromuscular junction.
Axon Hillock performs administrative duties by adding up all incoming signals, including inhibitory and stimulating. The action potential gets activated if this total surpasses the limiting threshold.
The neuron's cell body controls the structure of the neuron, houses its genetic material, and supplies energy for its various functions. Additionally, the dendrites' receiving information is processed by the cell body.
Dendrites gather and retain all data coming from the terminal of the axon. Dendrites get any incoming data or signals from the other neuron.
