Use the probe to check the percentage of carbon-14 remaining in the brown rock (rock 6) in the bottom layer. Next, change the pr

obe’s setting to Uranium-238 in the black box in the upper left corner. Check the percent remaining of this isotope. Why do you think that it is better to use uranium-238 instead of carbon-14 to check the age of a rock?

The dating performed with carbon 14 is only applicable to materials of organic origin, that is, that contain carbon in their constitution. To determine the age of the Earth, however, this type of dating is not feasible, as rocks are used to do this verification.

<h3>How is uranium 238 used for dating?</h3>

Uranium-238, whose half-life is 4.5 billion years, transmutes into lead-206, a stable end-product. Boltwood explained that by studying a rock containing uranium-238, one can determine the age of the rock by measuring the remaining amount of uranium-238 and the relative amount of lead-206.

<h3>What is carbon 14 what is it for?</h3>

Carbon 14 is a radioactive isotope of mass number 14, which is assimilated by all plant and animal organisms and is therefore used in fossil dating.

With this information, we can conclude that To determine the age of the Earth, however, this type of dating is not feasible, as rocks are used to do this verification.

You take a human smooth muscle cell and block the release of calcium from the sarcoplasmic reticulum. What effect does that have
Murljashka [212]

Answer:

The correct option is E) Contraction still occurs because Ca2+ can enter the cell directly through Ca2+ channels in the plasma membrane and bind to calmodulin.

Usually, the calcium ions are released from the sarcoplasmic reticulum of a cell during a muscle contraction, but if those are blocked, the contractions is an cell can still arise through the calcium ions which are present in the cell membrane of a cell.

Determine the correct order for the transmission of a signal through the nervous system.
Vinvika [58]

Answer:

A. I, IV, II, III, I

Explanation:

Living system can be defined as the internal systems of organisms and how materials circulate within organisms.

Generally, these living systems are self-organized life forms and are known to be very much interactive with their surroundings or environment. Also, living systems are dependent on the flow of information, matter and energy at various levels.

Some examples of living systems in organisms are respiratory system, nervous system, digestive system, and circulatory system.

Additionally, living systems comprises of the following components; cells, organs, muscle, tissues, blood, etc., which are typically used for carrying out various bodily functions such as respiration, metabolism, digestion, etc.

A sensory system can be defined as components of the central nervous system (CNS) which comprises of the brain, neural tissues or pathways and sensory neurons responsible for sensory functions, perception and processing sensory informations such as sound, light, heat, etc.

Basically, the central nervous system (CNS) interprete the neural signals that are generated from stimuli that are detected by the sensory system. The five (5) main sense organs in the sensory system are: skin, tongue, ears, nose and the eyes.

Generally, the nervous system found in living organisms such as humans, comprises of two (2) major components or systems; a central nervous system (CNS) and a peripheral nervous system (PNS).

The correct sequential order for the transmission of a signal through the nervous system;

1. Nerve impulse is triggered.

2. Synaptic vesicles release neurotransmitters.

3. Neurotransmitters diffuse across synaptic cleft.

4. Receptors bind neurotransmitters.

5. The whole process is started all over again when the nerve impulse is triggered.

A wilted flower placed in a vase of water for several hours became stiff and stood erect. when it was placed in a salt solution,
kherson [118]
The cell surface membranes of cells of flower, though semi-permeable, allows water to pass through cell via aqua proteins embedded in the membrane.
This is true since water goes from inside of cell to the extracellular environment when water potential inside the cell is higher than water potential outside the cell via process of osmosis (water goes from an area of high water potential down a concentration gradient to an area of low water potential). Cells in the flower became plasmolysed (cell surface membranes tear away from the cell walls) as the volume of water in cell decreases.

Hope this helps! :)
