Gravitropism ensures that roots grow into the soil and that shoots grow toward sunlight. Growth of the shoot apical tip upward is called negative gravitropism, whereas growth of the roots downward is called positive gravitropism.

What changes in agriculture have increased the potential for water pollution

Vinvika [58]

small chicken farms turned into factories because it was cheaper to

maintain and it also made it cheaper for people to buy eggs. However

this produced a huge problem of what to do with the chicken manure

and this is also a problem amongst other types of livestock as well as well as factories having big oil spills hope this helps sorry didnt know what you wanted for a answer

Comparing DNA Replication and Transcription

Explanation:

Some of the sequence of DNA given is in 3' to 5' direction, mRNA sequence is also given.

The DNA is double stranded helix which replicates by semi conservative mode. The two strands unwind to act as a template for other strands. In transcription the 3' to 5' strand acts as a template because RNA synthesis takes place in 5' to 3' direction. mRNA is single strand. It has nucleotides in it from which 3 base pairs acts as a code for amino acid.

The following table shows DNA strand having complementary sequaence and mRNA synthesized.

What are air particles doing in an undisturbed state?

seraphim [82]

Answer:

Air particles are a mixture of solids and liquids that are microscopically tiny and suspended by air currents. It can stay in the atmosphere for a few hours to a month or two. Their constituents can be various harmful substances such as heavy metals - lead, nickel, arsenic, cadmium or polycyclic aromatic hydrocarbons

Explanation:

Air particles, nitrogen dioxide and ground-level ozone are now considered to be the three most polluting substances in human health. Exposure during peak concentration and long-term exposure to these pollutants can cause damage from respiratory distress to premature death.

A nerve impulse from one neuron affects the activity of a neighboring neuron at a point of interaction called the:

tatyana61 [14]

Answer:

A nerve impulse from one neuron affects the activity of a neighboring neuron at a point of interaction called the: SYNAPSE

Explanation:

A NEURON(or nerve cell) has 3 parts:

1. The dendrites(multiple)

2. The axon

3. The cell body

A SYNAPSE is an area where the dendrites of one neuron communicates with the axon of another neuron.

At the synapse, nerve impulses are transmitted from one neuron to the other. This is possible through substances called NEUROTRANSMITTERS. There is no direct contact between the axon of one neuron and dendrites of another neuron.
