Explanation:
If a cell was producing too much energy, which component would step in to hold the
energy until it was needed?
rough endoplasmic reticulum
vesicles
lysosomes
mitochondria
Explanation:
Mitochondria is the answer
The component that would step in to hold excess energy until it's needed within a cell is the mitochondria.
The mitochondria are the cellular factories that turn food into adenosine triphosphate (ATP) through cellular respiration. A cell may store extra ATP within the mitochondria if it is making more energy than it needs right now. When the cell's need for energy rises, this stored energy can be released.
This mechanism makes sure that the cell effectively manages its energy resources and maintains energy balance. The primary role of other cellular components such vesicles, rough endoplasmic reticulum, and lysosomes is not in the storage of extra energy but rather in transport, protein synthesis, and waste disposal.

why are myxozoans actually a bad example of supposed evolution in action?
(I will give the best answer brainiest and extra points)
Explanation:
Myxozoans (phylum Myxozoa) are metazoan parasites utilizing invertebrate and (mainly) aquatic vertebrate hosts. They have in common with cnidarians the possession of virtually identical, highly complex organelles, namely the polar capsules in myxozoan spores, serving for attachment to new hosts and the nematocysts in surface epithelia of cnidarians, serving for food capture. Although myxozoan spores are multicellular, the simple trophic body forms of almost all species, reduced to syncytial plasmodia or single cells, reveal no clues to myxozoan ancestry or phylogenetic relationships. The myxozoan genus Buddenbrockia is one of only two known genera belonging to a clade which diverged early in the evolution of the Myxozoa. Today the Myxozoa are represented by two classes, the Myxosporea, containing all the better-known genera, which alternate between fish and annelids, and the Malacosporea, containing Buddenbrockia and Tetracapsuloides, parasitising bryozoans. The latter genus also infects salmonid fish, causing proliferative kidney disease (PKD). The enigmatic Buddenbrockia has retained some of its ancestral features in a body wall of two cell layers and a worm-like shape, maintained by four longitudinally-running muscle blocks, similar to a gutless nematode and suggestive of a bilaterian ancestry. Although some analyses of 18S rDNA sequences tend towards a cnidarian (diploblast) affinity for myxozoans, the majority of these studies place them within, or sister to, the Bilateria. The latter view is supported by their possession of central class Hox genes, so far considered to be synapomorphic for Bilateria. The simple body form is, therefore, an extreme example of simplification due to parasitism. Various hypotheses for the occurrence of identical complex organelles (nematocysts and polar capsules) in diploblast and triploblast phyla are evaluated: common ancestry, convergent evolution, gene transfer and, especially, endosymbiosis. A theory of the evolution of their digenetic life cycles is proposed, with the invertebrate as primary host and secondary acquisition of the vertebrate host serving for asexual population increase.
A drug that decreases the activity of an enzyme, by binding to its active site, is called _____?
Group of answer choices
a feedback activator
an active inhibitor
a competitive inhibitor
a noncompetitive inhibitor
A drug that decreases the activity of an enzyme by binding to its active site is called a competitive inhibitor.
An inhibitor may bind to an enzyme and block the binding of the substrate, for example, by attaching to the active site. This is known as competitive inhibition as the inhibitor “competes” with the substrate for the enzyme. In other words, only the inhibitor or the substrate can be bound together at a given moment.
If an inhibitor is competitive, it will decrease the reaction rate when there's not enough substrate, but can be "out-competed" by lots of substrates. That is, the enzyme can still reach its maximum reaction rate given there is enough substrate. Accordingly, almost all the active sites of the enzyme molecules will get replaced by the substrate rather than the inhibitor.

Which of these material properties for the thermal barrier coating would you select to reduce the operating temperature of the turbine blade?
a. a high thermal conductivity
b. a low thermal conductivity
c. a high thermal expansion coefficient
d. a low thermal expansion coefficient
b. a low thermal conductivity, is the correct option , these material properties for the thermal barrier coating would you select to reduce the operating temperature of the turbine blade.
A low thermal conductivity means that the material does not easily transfer heat. This is desirable for a thermal barrier coating because it acts as an insulator, preventing heat from flowing into the turbine blade and keeping the blade's operating temperature low. In other words, a low thermal conductivity helps to reduce the amount of heat that is transferred from the hot combustion gases to the turbine blade, thus reducing the temperature of the blade. This can help to increase the efficiency and lifespan of the turbine.

Zandile set up the following apparatus to investigate how temperature affects transpiration rate
Zandile found that as the temperature increased, the transpiration rate also increased, leading to increased water loss from the plant. This experiment helped her conclude that temperature directly affects transpiration rates.
Transpiration is the process of water movement through the plants from roots to leaves, and eventually lost by evaporation from the stomata. Various factors, including temperature, humidity, light, and wind, influence the transpiration rate.
Temperature affects transpiration as it affects the diffusion rate of water vapor from the leaves into the surrounding air.
To investigate how temperature affects transpiration rate, Zandile set up an apparatus comprising a potted plant, a beaker, and a thermometer. The plant was selected for the experiment, and its leaves were covered with a plastic bag to prevent any water loss through the leaves' surface.
The apparatus was set up in the following way: The plant was placed in a beaker containing water. The beaker was placed on a heat source, and the temperature was monitored with the help of a thermometer. The plastic bag was tied around the stem to ensure no air entered the plastic bag, making the experiment airtight.
Zandile then increased the temperature by placing the beaker on a heat source. She noted the temperature of the water in the beaker and the temperature inside the plastic bag. She continued to monitor the temperature and the rate of water loss from the plant.

A eukaryotic mutation upstream of a particular gene has been identified that changes the sequence of the TATA box to GATA. How would you predict that this mutation would affect the transcription of this gene
Answer:
Transcription factor binding would be reduced or eliminated, and transcription of the gene would decrease dramatically.
Explanation:
Mutation means the changing of the structure of the gene that results in the variant form which may be transmitted to the subsequent generations. They are caused by the altering the the single base units in the DNA of the species.
In both eukaryotic as well as prokaryotic, the mutation can affect the diversity in the future generation of the cells.
The eukaryotic mutation of the gene affects the transcription of the gene as the transcription factor binding will be lowered or will be eliminated and the transcription of this gene will decrease.
what does xylem utilize to move water
Xylem refers to the vascular tissue that moves water and other nutrients from the root of a plant where it is absorbed to the rest of it.
The xylem transfers water by utilizing transpiration. Transpiration is when water evaporates from a plant. It uses the tension created when water is pulled from the veins of the plant to refill them with the water recently absorbed by the roots.

Match the method of predator management to the challenges It faces. 1. use of firearms considered inhumane 2. use of poisons revised laws 3. use of traps inefficient and dangerous
Answer:
question
Explanation:
did you ever figure out what the answer was? please
Answer:
use of firearms- revised laws
use of posions -inefficient and dangerous
use fo traps- considered inhumane
Explanation:
Option 1 faces a challenge of revised laws. Although use of firearms was once a popular method of control, changes to laws, in particular those pertaining to wolves, have affected the issue. Option 2 faces a challenge of being inefficient and dangerous. Poison is illegal, largely because it is an inefficient practice that can be dangerous to both cattle and nonpredatory wild animals. Option 3 faces a challenge of being considered inhumane. The use of traps is an indiscriminate tool, like poison, often trapping the calves they are intended to protect.

How would you explain the key concepts for the CWA in less than two minutes?
Answer:
Explanation:
vPoint Source - a source of water discharged to surface water through a discrete point - generally through a pipe, ditch, or channel.
Nonpoint Source - Nonpoint sources, such as parking lots or athletic fields, discharge runoff water to groundwater or surface water; runoff does not come from a pipe, ditch, or channel. These sources may contain pollutants such as pesticides, motor oil, and soaps.
Navigable Waters of the United States For the purposes of the Clean Water Act, the term "navigable waters" includes:
all waters used in commerce, including groundwater;
all interstate waters including wetlands, mudflats, and sand-flats; and
all other waters such as lakes, rivers, streams, wetlands and sloughs.
EPA policy states, "The majority of facilities in the U.S. have the potential to discharge to navigable waters." The Supreme Court decision in (2006) requires the Army Corps of Engineers and the EPA to determine whether there is a "significant nexus" between a navigable waterway and an area a spill might affect. In June of 2007, EPA and the Army Corps of Engineers released provisional interpretive guidance regarding the "significant nexus” question. According to this guidance, the agencies will assert jurisdiction over traditional navigable waters, wetlands adjacent thereto, and relatively permanent tributaries thereof. The agencies will generally not assert jurisdiction over swales and ditches that lack routine water flow. Finally, the agencies will apply the "significant nexus" requirement and make a case-by-case, fact-specific analysis on impermanent tributaries and other wetlands.
Additional executive orders were issued 2015 in 2019. Under the 2019 proposal, traditional navigable waters, tributaries to those waters, certain ditches, certain lakes and ponds, impoundments of jurisdictional waters, and wetlands adjacent to jurisdictional waters would be federally regulated. It also details what are not "waters of the United States," such as features that only contain water during or in response to rainfall (e.g., ephemeral features); groundwater; many ditches, including most roadside or farm ditches; prior converted cropland; stormwater control features; and waste treatment systems.
Could the requirement for one or more NPDES Discharge Permit apply to my campus?
If your campus discharges pollutants directly to navigable waters of the United States through a point source, you must obtain an NPDES permit or redirect the flow of the waste.
Stormwater releases from certain activities require an NPDES permit. The most common activities on college campuses requiring NPDES permits for stormwater are construction activities disturbing more than 1 acre, hazardous waste storage areas operating under the Resource Conservation and Recovery Act permit system, steam-generating power plants, and airports. See Stormwater section below.
Regulations issued by local water authorities, or Publicly Owned Treatment Works (POTWs), not NPDES permits, govern discharges into sanitary sewer systems. See Sewer Use (POTW) section below for more information about requirements for using POTWs for commercial or industrial waste disposal.
What do I have to do related to NPDES Discharge Permits?
Determine where wastewater flows from buildings and processes on your campus. Any industrial or commercial operation (e.g., ice rink melt pits, floor drains, and vehicle wash stations) that discharge into a water of the United States may require an NPDES permit. If required, you must obtain such a permit from the appropriate regulatory agency, probably your state environmental agency.
French drains, dry wells, and septic system leach fields are different from point source discharges because they do not immediately affect surface water. Some state and federal environmental agencies manage these systems under the Underground Injection Control program, part of the Safe Drinking Water Act. See Safe Drinking Water Act for more information.
