Answer:
In relative dating, fossils are dated according to the depth at which they were buried. ... While in the absolute dating, isotopes of carbon are used for dating fossils. The absolute dating is more precise than relative dating because it tells the exact age of the fossils.

What is a substrate?
a molecule that acts as a catalyst
a place on the enzyme where the reaction occurs
a place on the product where the enzyme fits
a reactant that is catalyzed by an enzyme
Answer:
D. a reactant that is catalyzed by an enzyme
Explanation:
A substrate is a reactant that is catalyzed by an enzyme. Therefore, the correct statement is option D.
What is a catalyst?A substrate is a reactant molecule that binds to the active site of an enzyme and the enzyme then chemically transforms the substrate through a series of catalytic reactions.
Enzymes are the catalysts that are used to increase the rate of biochemical reactions by lowering down the activation energy that is required for the reaction to occur. The substrate when binds to the active site of the enzyme, it forms an enzyme-substrate complex followed by its conversion into one or more products. When the product is formed, enzyme gets released from the product.
A catalyst is a substance which is used to lower down the activation energy required by the reaction, thereby, increasing the reaction rate to form a product.
Therefore, substrate is a reactant that is catalyzed by an enzyme.

When light intensity is below above 400 umol photons/m2/s, do sun plants or shade plants have a higher rate of photosynthesis?
Answer:
-Abiotic factors such as light, water, and temperature
-The more light, the faster the plant is able to photosynthesize, however, plants reach its level of maximum photosynthesis if the intensity of light is too high
-Temperatures above or below range of 0 degrees Celsius and 35 degrees C can cause damage to enzymes, ceasing photosynthesis
-If too much or too little water is applied, plant cells may wither and die, or explode
Explanation:
When environmental light intensity is below 400 umol phs/m²/s, shade plants have a higher photosynthetic rate. Above this level, sun plants have a higher rate of photosynthesis.
---------------------------------
The photosynthetic rate depends in part on the plants' environment.
Being all conditions favorable -light availability, water, and temperature level-, photosynthesis intensity increases with light intensity.
The more light intensity and exposure, the better and faster the plant photosynthesizes.
However, there is a limit for all these environmental factors over which the photosynthetic rate can be affected or reach its maximum point.
Concerning light, there is an intensity level when exposed to a standard unit of light intensity, at which plants express their highest photosynthetic rate.
It depends, among other reasons, on the type of plant.
Shade plants
Low levels of light are enough for plants that grow in the shade.
Shade plants can express their highest photosynthetic rate at intensities of 400 umol photons/m²/s. From this point on, the photosynthetic rate remains equal.
Sun plants
On the other hand, plants that grow in the sun need much higher levels of light to express their highest photosynthetic rate.
Sun plants keep increasing their photosynthetic rates at intensities higher than 400 umol photons/m²/s, expressing their highest performance near 1000 umol photons/m²/s.
Comparing both types of plants,
At lower light intensity (0-300 umol photons/m²/s), the photosynthetic rate of shade plants is higher than the one of sun plants.
Near 400 umol photons/m²/s, the photosynthetic rate of both types of plants is almost equal.
Over 400 umol photons/m²/s, the photosynthetic rate of shade plants reaches their maximum level, while the sun plants one keeps increasing.
Between 800 -1000 umol photons/m²/s, the photosynthetic rate of sun plants reaches their maximum level.
According to this information,
below 400 umol photons/m²/s, shade plants have a higher rate of photosynthesisabove 400 umol photons/m²/s, sun plants have a higher rate of photosynthesis

Describe the term "semi-permeable" (or "selectively-permeable) membrane. Why is it important?
Answer:
A semi-permeable membrane is a type of biological or synthetic, polymeric membrane that will allow certain molecules or ions to pass through it by osmosis. The rate of passage depends on the pressure, concentration, and temperature of the molecules or solutes on either side, as well as the permeability of the membrane to each solute. Depending on the membrane and the solute, permeability may depend on solute size, solubility, properties, or chemistry. How the membrane is constructed to be selective in its permeability will determine the rate and the permeability. Many natural and synthetic materials which are rather thick are also semipermeable. One example of this is the thin film on the inside of the egg.
Explanation:
An example of a biological semi-permeable membrane is the lipid bilayer, on which is based on the plasma membrane that surrounds all biological cells. A group of phospholipids (consisting of a phosphate head and two fatty acid tails) arranged into a double layer, the phospholipid bilayer is a semipermeable membrane that is very specific in its permeability. The hydrophilic phosphate heads are in the outside layer and exposed to the water content outside and within the cell. The hydrophobic tails are the layer hidden in the inside of the membrane. The phospholipid bilayer is most permeable to small, uncharged solutes. Protein channels are embedded in or through phospholipids, and, collectively, this model is known as the fluid mosaic model. Aquaporins are protein channel pores permeable to water. Information can also pass through the plasma membrane when signaling molecules bind to receptors in the cell membrane. The signaling molecules bind to the receptors, which alters the structure of these proteins. A change in the protein structure initiates a signaling cascade. The G protein-coupled receptor signaling provides is an important subset of such signaling processes.

If the potential difference across a 30.0-ohm resistor is 10.0 volts, what is the current through the resistor?
O A 0.25 A
OB 3.0 A
OC 0.33 A
OD. 0.50 A
Answer:
C 0.33 A
Explanation:
The current through the resistor can be calculated using the formula;
V = IR
Where; V = Voltage (volts)
I = Current (Ampere)
R = Resistance (Ohms)
According to this question, I = ?, V = 10.0volts, R = 30.0ohms
V = IR
I = V/R
I = 10/30
I = 0.33A
Hence, the current through the resistor is 0.33A
Which of the following is not a reason that nonnative species are reared outside their native ecosystems?
a. They are commercially important.
b. They are used to replace native species.
C. They are used for restocking programs.
d. None of the above
Answer:
D
Explanation:
All of the given reasons are reasons that nonnative species are reared outside their native ecosystems. The correct option is D.
What are nonnative species?Non-native species are animals, plants, and other organisms that do not develop natively in a region but are instead introduced through intentional or unintentional human activity.
Non-native species, unlike invasive species, do not necessarily threaten or threaten the existence of other species within the ecosystem.
Native plants and animals may go extinct as a result of invasive species, which can also decrease biodiversity, compete with native species for scarce resources, and disrupt habitats.
Ecosystems along the coast and in the Great Lakes may be severely disrupted, with significant negative economic effects.
They are employed in restocking efforts, to replace native species, and for commercial purposes.
Thus, the correct option is D.
