Upwelling refers to the process in which deep, cold, nutrient-rich water from the ocean's benthic zone rises to the surface. The correct option is D. Water moving up from the benthic zone.
Upwelling usually occurs along coastlines, where wind patterns and ocean currents interact to push surface water away from the shore. As the surface water moves away, it creates a void that is filled by the upward movement of colder water from below. This cold water brings nutrients to the surface, which promotes the growth of phytoplankton and supports the productivity of marine ecosystems.
Upwelling is vital for sustaining marine life and is known for creating areas of high biological productivity, as it provides nutrients for the growth of primary producers, which in turn support the entire food web.
Therefore, the correct option is D. Water moving up from the benthic zone.

Help please I’ll make u the brainlest
Answer:
The correct option is B) Photosynthesis.
Explanation:
Photosynthesis can be described as a process in which plants convert carbon dioxide and water into oxygen and glucose by using light energy from the Sun. Photosynthesis is a process that occurs in plants, some algae and cyanobacteria. Hence, option B is correct.
Other options like option C are false because, during aerobic respiration, oxygen is utilized instead of being produced. The process of respiration is opposite to the process of photosynthesis.

How is the water cycle related to the Carbon oxygen cycle
Answer:
The water cycle uses plants for uptake of water and transpiration from the surface, so that water can be sent to the atmosphere.
Carbon cycle uses plants for uptake of CO2, by which it is removed from the atmosphere (and sent back to atmosphere when the plant is dead).
Explanation:
Both the cycles use plants as an integral component. Both the water cycle and carbon cycle use subsurface for long term storage. The water forms groundwater and can be stored for long duration. Similarly, carbon is stored in rocks for long term.
After our solar system began to form, dust and gas combined into small bodies that formed the planets. What are these small bodies called?
dwarf planets
gas giant planets
planetesimals
terrestrial planets
Answer:
planetesimals
Explanation:
:)
The small bodies that formed the planets after the solar system began to form are called planetesimals; this is the third option, as the planetesimals are essentially small, rocky or icy bodies that formed in the early stages of the solar system's formation.
what is Planetesimals ?They were the building blocks that eventually collided and merged to form larger bodies, such as planets and moons. Terrestrial planets, like Earth, Mercury, Venus, and Mars, are formed from the accretion of these planetesimals. The planetesimals collided and stuck together, growing larger and larger until they became the solid, rocky planets we know today. Dwarf planets, on the other hand, are also small bodies in our solar system, but they did not clear their orbits of other debris, which is one of the criteria used to distinguish a planet from a dwarf planet.
Hence, the small bodies that formed the planets after the solar system began to form are called planetesimals, which is the third option.

A ionization of particles
B compressibility
C particle motion
D ability to conform to container
Answer:
A= ionization of particles
Explanation:
Plasma:
" The ionized gaseous mixture consist of atoms, ions and electrons is called plasma"
The plasma was first time identified by William Crookes in 1879. More than 99% universe matter is consist of plasma.
It is the fourth state of matter, the other three are solid, gas and liquid. The most of matter in the universe is plasma. When heat is supplied to the atoms, they gain energy the electrons in atom thus escape from the atom by gaining the energy and create the positive charge. Thus ions are formed. When heat is constantly supplied, the ionization process continue to take place and produce large number of positive charges, free electrons but some atoms not get ionized and remain neutral. Thus a cloud of free electrons , positive charge and neutral atoms is formed which is called plasma.

Describe the biotic and abiotic features of the deserts
Which phrases describe an irregular galaxy?
what phrase are you talking about?
An irregular galaxy is one that lacks the defined shape of spiral or elliptical galaxies, often has active star formation, and contains both young and old stars. They can be reshaped by gravitational forces or collisions, and historical observations show that they were more common in the past.
Phrases that describe an irregular galaxy include not having regular shapes like spiral or elliptical galaxies, typically possessing lower masses and luminosities compared to spiral galaxies, appearing disorganized, and often experiencing relatively intense star formation activity. Irregular galaxies contain a mix of young population I stars and old population II stars, highlighting their diverse age range. These galaxies can be subjected to deformation by gravitational interactions with more massive galaxies or collisions with other galaxies, leading to their irregular shapes. The majority of galaxies are irregular, and the Large and Small Magellanic Clouds are examples of such irregular galaxies. In the distant past, irregular galaxies were more common and frequently interacting, as seen in deep field observations like the Hubble Ultra Deep Field.

Explain how antibiotic resistance in bacteria provides evidence that supports Darwin’s theory of evolution
Answer and Explanation:
Some pathogens and pests usually survive and reproduce even when they are exposed to the antibiotics and pesticides repeatedly. These instances show that within the population soe individuals possess the gene for resistance or acquire it through mutation hence survives the chemical. Those that survive transmit this characteristic to their offsprings thus establishing a new population of resistant forms.
Optical Microscopes: Explain the benefits of a higher resolution
Optical Microscope - Resolution
Explanation:
Optical microscope resolution is the shortest length between any two closely located bright points on the specimen which can be viewed clearly by the viewer.
The resolution ability of an optical microscope is specified by how it distinguishes these two airy disk points which are closely placed on the specimen.
In optical microscope, with higher magnification, the image may get blurred or unsharp which can be corrected depending upon its objective. The resolution increases with increase of the numerical aperture of the entire system.
The resolution of an optical microscope is around 200 nm with a magnification power of about 1000. This resolution is less compared to that of an electron microscope .

In Eukaryotas the energy sources obtained in the form of the sunlight.
Final answer:
Both prokaryotic and eukaryotic cells can extract nutrients from available resources, despite differences in cellular structure such as the presence or absence of a nucleus.
Explanation:
The answer to the question is based on an understanding of cell theory and cellular structures in different types of organisms. The cell theory states that all living organisms are composed of cells, and these cells are the basic unit of life. Additionally, it states that new cells arise from existing cells. Both prokaryotic and eukaryotic cells are capable of extracting nutrients from available resources, despite the presence or absence of a nucleus. Prokaryotic cells, which lack a nucleus, manage cellular processes in different ways than eukaryotic cells, which possess a nucleus; however, both types are equipped to obtain and process nutrients necessary for survival.

describe how microbial control agent's affects microbes
Answer:
Microbial control agents can be described as agents which will inhibit or prevent the growth of microbes. Hence, they will prevent the damages caused by microbes.
Microbial control agents can either inhibit the growth of microbes. In this way, the population of the microbes will not expand and hence, the effect of the microbe on a host will be controlled.
Other microbial control agents kill the microbes and hence, control the effect of microbes.
Microbial control agents affect microbes by inhibiting cell wall synthesis, protein synthesis, DNA replication, transcription, damaging cytoplasmic membranes, and disrupting metabolic pathways.
Microbial control agents, such as antibiotics and disinfectants, exert their effects on bacteria through various mechanisms. These agents can target and damage critical bacterial structures and macromolecules, leading to the inhibition or death of the microbial cells. Here are six different ways in which these chemical agents can affect bacteria:
Cell wall synthesis inhibition: Some agents prevent the synthesis of peptidoglycan, weakening the cell wall and leading to cell lysis.Protein synthesis interference: Agents can bind ribosomes, inhibiting translation and thus preventing the bacteria from producing essential proteins.DNA replication and repair disruption: Certain antibiotics can bind to bacterial DNA or DNA-processing enzymes, preventing replication and repair.RNA polymerase inhibition: By binding to and inhibiting RNA polymerase, some agents block the transcription process within the bacterial cell.Cytoplasmic membrane damage: Disinfectants may disrupt the integrity of the bacterial membrane, causing leakage of cell contents.Metabolic pathway disruption: Antibiotics may interfere with essential metabolic pathways, such as folic acid synthesis, crucial for bacterial growth.The effectiveness of these agents varies among different bacteria, with some species being naturally resistant or developing resistance over time. Gram-positive bacteria and Gram-negative bacteria may respond differently to various control agents due to structural differences in their cell walls.

Answer:
C. is the correct answer. Sea level, Pacific Ocean, 1955 to 1975.
Explanation:
Letter C is the correct link because you are looking for the change in the height of an ocean over a 20 year period of time.
The reason for this is because A only has names of oceans, therefore wouldn't help you find the changes in height or the number of years. B has volume, density, and temperature, but you are not trying to find the mass of the ocean. Finally, D has the wind speed, pH, and salinity, and you are not looking for any of those.

the plastic baggie was permeable to which substances ?
The plastic baggie was permeable to Iodine.
Explanation:
The plastic bag is a good example of the cell membrane as it is semipermeable. Experiments show that a plastic bag is semipermeable. Take corn starch nin a plastic bag and dissolve it in water. Now take a beaker with water and add Iodine indicator. The colour changes to brown.
Place the plastic bag inside the beaker. After some time the colour of the starch solution turns blue from white. But the solution in the beaker is of the same colour.This shows that the plastic bag has numerous tiny holes and thus acts like a semipermeable membrane allowing Iodine to pass through it. Apparently it retains the large starch molecules from passing out.

22. Explain briefly the 2 roles oxygen plays in cellular respiration
Answer:
It combine with hydrogen and two electrons form water.
It is necessary for our breathing.
Explanation:
Oxygen during cellular respiration is very important.
It combine with hydrogen and two electrons form water.
It is necessary for our breathing. cellular respiration take place effectively in the presence of oxygen and produced more ATP.
There are two types of respiration:
1. Aerobic respiration
2. Anaerobic respiration
Anaerobic Respiration
It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.
Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide
Aerobic respiration
It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
Glucose + oxygen → carbon dioxide + water + 38ATP
Explain the induced fit of an enzyme reaction including what happens to the substrate after the reaction has taken place
Answer:
The induced fit model explains that the active site of an enzyme changes slightly so that a substrate can fit into it. This is a modification of the lock and key model according to which no changes occurred in the active site of the enzyme.
The induced model explains that the active site undergoes changes to fit the substrate. After the substrate is catabolized or anabolized, it gets detached from the active site. The active site then takes its usual shape back until next substrate arises.
