geologic layers?
They were laid down around the same time
Sandstone is older than the shale
Shale is older than the sandstone
Since they are from different locations, unless we can radiometric Lee date them, we cannot distinguish anything between the two
Answers
Answer:
Since they are from different locations, unless we can radiometric Lee date them, we cannot distinguish anything between the two
Explanation:
It is not possible to determine information about the geological layers of different locations just by viewing the images, as the question above asks. This is because these two sites have different natural elements that acted on these layers and these fossils differently. In this case, making conclusions only with the visualization of the images, would not promote accurate and correct information. Ideally, a radiometric dating would be performed in both cases, so that accurate conclusions could be created.

Which types of mutations in the lac operon stop Escherichia coli from utilizing lactose as a carbon source? a) promoter deletion b) lactose-binding site mutation c) repressor DNA-binding site mutation d) operator deletion
Answers
Answer:
D.) repressor DNA-binding site mutation
Explanation:
lacl prevents the repressor polypeptide is a mutant that prevent operon from binding lactose, and thus will bind to the operator and be non-inducible.. This mutant will represses the lac operon whether lactose is present or not and the lac operon will not be expressed. It is also called“super-supperesor".
The lacI locus – One type of mutant allele of lacI (callled I-) prevents the production of a repressor polypeptide or produces a polypeptide that will not allow to bind to the operator sequence.
This is also a constitutive expresser of the lac operon because absence of repressor binding permits transcription.
How do healthy cell decide when to divide?
Answers
Answer:
Cells regulate their division by communicating with each other using chemical signals from special proteins called cyclins. These signals act like switches to tell cells when to start dividing and later when to stop dividing.
A healthy cell decides when to divide by sensing and receiving signals from its surrounding environment.
The cell cycle can be divided into interphase and a mitotic (M) phase.During the interphase, the cell synthesizes all materials required (i.e., proteins, DNA, etc) to divide during the M phase.During the cell cycle, a cell modulates its division by communicating with other cells via specific chemical messenger molecules known as cyclins. Cyclins are proteins that interact with Cyclin-dependent kinases (CDKs) and thus function as molecular switches that regulate the progression through the cell cycle.In conclusion, a healthy cell decides when to divide by sensing and receiving signals from its surrounding environment.

If the atomic number of an element is 6 and its mass number is 13, how many neutrons
are
contained in the nucleus?
19
8
7
6
Answers
Answer:
There will be 7 neutrons in a carbon isotope with an atomic mass of 13.
Explanation:
The number of protons in the carbon isotope will be the same as the atomic number, 6, so if we need an atomic mass of 13 there will be 7 neutrons, as 6+7=13.
If the atomic number of an element is 6 and its mass number is 13, there will be 7 neutrons. Therefore, the correct statement is option C.
What is atomic number?Atomic number is the number of protons found in the nucleus of an atom of a specific chemical element. The atomic number is also equal to the number of electrons orbiting around the nucleus in a neutral atom.
Mass number is the total number of protons and neutrons found in the nucleus of an atom and is represented by the symbol A. The mass number is used to determine the atomic mass of the atom.
The atomic number of an element is the number of protons present in its nucleus, which is 6. The mass number of an element is the total number of protons and neutrons in its nucleus, which is 13. So, the number of neutrons in the nucleus can be calculated by subtraction of the atomic number from the mass number.
The formula is number of neutrons = Mass number - Atomic number.
Therefore, there are 7 neutrons in the nucleus of the given element.

A. Designing nets that release unwanted species without harming them.
B. Using the net in deeper regions of the ocean where different organisms live.
C. Decreasing the size of the nets, but using more of them.
D. Exploring new and uncharted areas of the ocean where the nets can be used.
Answers
Answer:
A. Designing nets that release unwanted species without harming them.
Explanation:
Over-fishing is a negative human practice that leads to the over-exploitation of aquatic ecosystems (i.e., both marine ecosystems and freshwater ecosystems). In an aquatic ecosystem, the communities of organisms coexist in a delicate balance where they are dependent on each other in the food web, providing stability to the whole ecosystem. Therefore, the over-exploitation of any aquatic species is expected to impact the whole ecosystem, thereby also having a negative impact on other fish populations.
Compare the exoskeletons of two invertebrates: a grasshopper (Arthropod) and a clam (Mollusca). How do they differ in relation to support and movement?
Answers
Answer:
Mollusca: Unsegmented exoskeleton, with no appendixes articulated to them. This skeleton has a calcareous origin. Arthropoda: Segmented exoskeleton, with different appendixes articulated to them, which develop different functions. This skeleton has a chitinous origin.Explanation:
Clams are bivalves. Their calcareous exoskeleton has two valves dorsally articulated to each other. They do not articulate with any appendix, although. These animals also have a foot, a small head, and a developed mantle cavity. The valves are convex, oval, and unsegmented. They are composed of three layers: periostracum, prismatic, and pearly. En the dorsal portion of each valve, there is a bulge called the umbo, which is the oldest part of the valve. The articulation has some teeth-shaped structures that are intercalated, maintaining the valves together and fixed. Grasshoppers have a chitinous exoskeleton divided into three principal segments or regions that allow their movement: head, thorax, and abdomen. The head is orientated in such a manner that their feeding apparatus is heading down. Also, the head segment has composed eyes and antennae. The thorax is the medial region of the body. It has three segments: the prothorax, mesothorax, and metathorax. Each of these segments articulates with a pair of legs. Finally, the abdomen is composed of many segments that might reach up to 7 or 11.If there is a logarithmic relationship between stimulus intensity and action potential frequency in sensory neurons, how much will the action potential rate increase if the stimulus intensity increases by 100?
Answers
Answer:
The action potential rate will be doubled
Explanation:
The logarithm of a number for a given base is the power to which the base must be raised to give the number. Logarithm of a number can be in different bases. The base of common logarithm is the base 10.
For example, logarithm of 1000 to base 10 is 3 because 10 raised to power 3 equals 1000
Log₁₀1000 = 3 since 10³ = 1000
Therefore, if there is a logarithmic relationship between stimulus intensity and action potential frequency in sensory neurons and the stimulus intensity increases by 100, the action potential rate will increase thus:
Log₁₀100 = 2
Therefore, the action potential rate will be doubled
