Some people have low levels of calcium circulating in the blood, a condition known as hypocalcemia. while for many this disorder

has little to no effect, for some it can be life-threatening. how could low levels of calcium harm an individual? low levels of calcium would not have any effect on synaptic transmission. low levels of calcium would result in fewer signals sent between the pre- and postsynaptic cell. low levels of calcium would cause sustained depolarization of the presynaptic cell.

Answer:

low level of calcium would result in fewer signals sent between pre and post synaptic cells.

Explanation:

The calcium has a main role in signal transmission mechanism and here is the mechanism :

1-the impulse reaches the synapse (depolarization which is a voltage change).

2-the voltage gated calcium channels open and let calcium flow into the cell.

3-the calcium causes the synaptic vesicles to rupture and release chemical transmitters which cross the synaptic cleft and finally bind to receptors on the post synaptic cell (transmitting the signal)

so it's obvious that if calcium concentration decreases, the signal transmission also decreases.

Recall what you know about nervous tissue to answer the following questions. Nervous tissue can generate and conduct ____ signal
Dimas [21]

Answer:

Nervous tissue can generate and conduct <u>electrical</u> signals that control the body.

Explanation:

The neuron is the specialized cell that provides function to nerve tissue. Given the structure of the neuron, this cell is capable of creating and conducting information in the form of electrical impulses or signals, by depolarizing its cell membrane and generating action potentials.

The information generated and transmitted by the neurons allows the nervous system to obtain internal and external information of the organism, as well as to control all the body functions.

<em>     The other options are not true because nerve tissue does not generate or conduct </em><em>thermal </em><em>or</em><em> chemical </em><em>signals to perform its function.</em>

Tropical rainforests have high species richness of trees. Provide the most reasonable explanation why animal species richness is
AfilCa [17]

Answer:

Here, is the question with the explanations to pick from to complete the question

Tropical rainforests have high species richness of trees. Which of the following statements provides the MOST reasonable explanation why animal species richness is also high in tropical rainforests?

Animals are unable to adapt to climate variability in higher latitudes.

Animals have had the same amount of time to evolve in rainforest areas as trees.

Animal diversification rates are higher than those of trees.

Animals have diversified into the vast number of niches provided by tree diversity

The last option is the most reasonable one

Our answer is:

Animals have diversified into the vast number of niches provided by tree

Explanation:

The reason is that a lot of species are highly specialized to occupy a particular niche. Where that favourable niche exists, the population of that species increases as its offspring colonize new areas.

A fossil mold that reflects the shape and surface markings of an organism is created when _____.
Lady bird [3.3K]

Correct answer: D). The organism is buried in sediment and then dissolved by underground water

Mold is a copy of an organism, it is formed like the first layer of sediments harden and forms a mold. Then after that new layer of sediment fills and become hardens.

The fossil is left behind in sediment, which removes the remains of an organism from its surrounding material. The groundwater along with its mineral content dissolves the organic matter to form the fossil.
