Answer:
Prokaryotic cells can only regulate gene expression by controlling the amount of transcription. As eukaryotic cells evolved, the complexity of the control of gene expression increased. For example, with the evolution of eukaryotic cells came compartmentalization of important cellular components and cellular processes.

EXPLAIN How have advancements in computer technology most directly influenced our
knowledge of wildlife and the ecosystems in which they live?
Advancements in computer technology most directly influenced knowledge of wildlife and ecosystems by spreading information about them, about their role in ecosystems, their importance, etc.
What is ecosystem and wild life?
Ecosystems consist of both living organism and non-living substances. Examples of ecosystems are the grassland ecosystem, the ocean ecosystem, the desert ecosystem, etc. In a grassland ecosystem, all organisms, such as plants, animals, and bacteria, work together in coordination. Different ecosystems have different wild lives . Example: In a forest ecosystem, there are tigers, elephants, lions, donkeys, etc.
They are affected by different human-made activities as well as by natural calamities such as earthquakes. The concerns about the changing ecosystem and its impact on wild life, such as the impact of climate change on them and global warming, are highlighted due to the advancements in computer technology. Activists and the general public spread awareness about them.
Hence, in this way, the advancements in computer technology help spread awareness among people about wildlife and the ecosystems .

Describe why some water uses are called consumptive
Answer:
Consumptive rates are so high because water that is applied to a field is considered lost to the immediate water system. It either gets evaporated, used by the plants, or leaves the field as run-off. In addition, leaks or evaporation cause loss while water is being transported from the source to the field, often over great distances.

Which of the following evidence supports the theory of plate tectonics?
The age of rocks and mountains on the edge of neighboring continents varies.
Fossils from the same species are found on only one continent.
Iron-rich, molten magma rocks no longer align to Earth’s poles in many locations.
Grooves created from glacier movement travel in opposite directions on each continent.
The characteristics of the tectonic plates allows to find the result for the correct statement is:
Iron-rich, molten magma rocks no longer align to Earth’s poles in many locations.
The tectonic plate model establishes that by the hot magma convection currents the solid crust breaks in the weakest areas, forming plates that move floating on this, hot magna that can rise through the cracks and separate these plates.
In the attached we see a diagram of the magnetic alignments in the rocks from a tectonic plate, we can see that the alignment changes due to the inversion of the earth's magnetic field in such a way that we can appreciate the separation of the two plates.
Another proof is that other similar animals are on continents separated by great distances.
Let's analyze the different claims:
a. False. Radioactive dating evidence gives that the rocks give that the rocks on the two continents are the same age.
b. False. Fossils of the same spice are found on several continents.
c. True. These rocks when they emerged were aligned and when moving and the magnetic field reversed the rocks are no longer aligned, this is one of the greatest proof of the separation of tectonic plates.
d. False. The furrows of the glaciers go from the North to the South, it does not have the direction of the displacement of the plates.
In consequence of the characteristics of the tectonic plates we can find the result for the correct statement is:
Iron-rich, molten magma rocks no longer align to Earth’s poles in many locations.

Is a process that tells cells to stop dividing if they touch each other
Answer:
contact inhibition.
Explanation:
This is how healthy cells know when to stop dividing. and a process called contact inhibition is when normal, healthy cells are touching other cells on all sides, they have a red light in the cell cycle and do not divide
I Hope This Helps!!!!
Answer:
cell cycle
Explanation:
The process then repeats in what is called the cell cycle. 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. I don't understand what you are saying, but hope this helps!

Question
Cocaine, amphetamine, and MDMA are all central nervous ________ that agonize dopamine neurotransmission.
Cocaine, amphetamine, and MDMA are all central nervous stimulants that agonize dopamine neurotransmission.
How do these stimulants affect the central nervous system?Cocaine, amphetamines, caffeine, nicotine, and MDMA (ecstasy) all cause the nervous system to become more active.
In biology and medicine, chemicals that hasten the transmission of messages between nerve cells are referred to as stimulant drugs. These chemicals include caffeine, nicotine, cocaine, and ecstasy.
Dopamine accumulates excessively between nerve cells as a result of cocaine's ability to stop it from being recycled. The high from cocaine is eventually brought on by this dopamine overflow, which interferes with regular brain activity.
Therefore, stimulant medicines have the ability to speed up the rate at which messages are transferred inside the nervous system.

Explanation:
Among the given options, The odd one out is sugar. Sugar is a type of carbohydrate that is used for energy.
Leaf of a plant: A leaf is a green organ of a plant that is responsible for photosynthesis.
Horse muscle: Muscle is a type of tissue that is responsible for movement.
Blood: Blood is a fluid that circulates through the body and carries nutrients, oxygen, and waste products.
Sugar: Sugar is a type of carbohydrate that is used for energy.
Sugar is the only one of these four that is not a living organism. The other three are all living organisms: the leaf of a plant, a horse muscle, and blood.
Here is a more detailed explanation of why sugar is the odd one out:

Which pH indicates a basic solution?
1.
1
2.
5
3.
7
4.
12
Answer:
7
A pH value greater than 7 indicates a basic solution. The more the pH value exceeds 7, the more basic is the solution.
7 is the answer.
If the pH is 1, that means the substance is sour or acidic.
If it has a pH of 5, then it is not that acidic.
If something has a pH of 12, then it is almost completely basic.
If something has a pH of 7, then it is basic.

what happens when a normal protein is embedded into the cell membrane.
Thyroid hormone receptor (TR) regulates growth, development, and differentiation of mammals. TR contains both a domain that binds to T3, the thyroid hormone, and a separate domain that binds to DNA. Which of the following BEST explains how TR signals?
A. T3 binds to TR at the cell membrane, which then releases second messengers to regulate gene expression.
B. T3 binds to DNA at the cell membrane, which then releases second messengers to regulate gene expression.
C. T3 diffuses through the cell membrane to bind to TR, which then binds to DNA to regulate gene expression.
D. T3 diffuses through the cell membrane to bind to DNA, which then binds to TR to regulate gene expression.
Answer:
C. T3 diffuses across the cell membrane, attaches to Tr, and then binds to DNA to control gene expression.
Explanation: Thyroid hormone, as a ligand, diffuses across the plasma membrane, then searches for the nucleus TR (Thyroid receptor and RxR aie heterochimeric bind to DNA).
When Thyroid Hormone binds to the A domain of T3, Corepressor Proteins are removed, which stimulates gene transcription.
