Installation of low flush toilets in home is considered as way to conserve the fresh water.

Answer: C

Explanation:

Fresh water must be conserved as its availability is very low.

All the process which utilizes water must be checked and ensured that water is judicially used.

Among the given option, the best way to conserve the fresh water is to install low-flush toilets at homes.

The low flush toilets help in conservation of high amount of water as it reduces the water usage from 3.5 - 7 gallons to 1.6 gallons per flush.

This helps in high water conservation.

Sergio [31]

Answer:

If an inhibitory synapse fires at the same time and at the same distance from the initial segment as an excitatory synapse of the same intensity there will be no changes in the potential in the firing zone.

Explanation:

Under normal conditions, the transmembrane potential depends on the ionic charges present in the intracellular and extracellular spaces. The extracellular space load is usually positive and in the cytoplasm is negative.

<u>Depolarization</u> occurs by opening ion channels that allow sodium to enter the cell, making the intracellular space more positive.
An opening of potassium channels releases this ion to the extracellular space, leading to <u>hyperpolarization</u>.

An excitatory synapse is one capable of depolarizing a cell and boosting the production of action potential, provided it is capable of reaching the threshold of said potential.

On the other hand, an inhibitory synapse is able to hyperpolarize the cell membrane and prevent an action potential from originating, so that they can inhibit the action of an excitatory synapse.

The interaction between two synapses, one excitatory and one inhibitory, -called synapse summation- will depend on the strength that each of them possesses. In this case, the intensity of both synapses being the same, there will be no changes in the membrane potential in the firing zone.

Genes A and B are 10 map units apart and genes B and C are 20 map units apart, with gene B located between genes A and C. What w

Marizza181 [45]

Answer:

2% of the progeny will be double crossovers for the trihybrid test cross

Explanation:

By knowing the positions of genes, we can estimate the distances in MU between them per region.

Genes A and B are 10 map units apart (Region I)
Genes B and C are 20 map units apart (Region II)
Genes A and C are 30 map units apart

----A-------10MU--------B-------------20MU-------------C---

Region I Region II

We can estimate the recombination frequencies by dividing each distance by 100.

• recombination frequency of A-B region = 10MU / 100 = 0.10

• recombination frequency of B-C region = 20MU / 100 = 0.20

Now that we know the recombination frequencies in each region, we can calculate the expected double recombinant frequency, EDRF, like this:

EDRF = recombination frequency in region I x recombination frequency in region II.

EDRF = 0.10 x 0.20 = 0.02

2% of the progeny will be double crossovers for the trihybrid test cross
