The difference between a grade of meat and to cut of meat is that grade of meat is used to define the quality of meat whereas the cut of meat is used to describe the quantity of meat.
The grades given to meat by USDA are known as an image of high-quality, secure, and solid American hamburgers. Quality grades, inside the cattle generation industry, are utilized as a dialect to create trade exchanges simpler.
Utilizing this evaluating framework, producers, as well as customers, appreciate a few benefits. The USDA has made an add up to eight grades and as it were five grades of them and being made accessible within the showcase for customers.

What else is missing from this equation that a plant needs in order to do photosynthesis?
A plant needs carbon dioxide and light energy in order to perform photosynthesis.
Commonly used equation for photosynthesis is: [tex]6CO_{2}[/tex] + [tex]6H_{2}O[/tex] → [tex]C_{6}H_{12}O_{6}[/tex] + [tex]6O_{2}[/tex]. This illustrates how light energy is absorbed by chlorophyll (implied by the arrow) to turn the reactants, six carbon dioxide molecules and six water molecules, into a sugar molecule and six oxygen molecules, the products.
Photosynthesis is a process by which the plants use light energy and carbon dioxide from the atmosphere to convert into glucose sugar and oxygen. Oxygen is required by every living organism to respire and live. Whereas, glucose produced is used by plants as their food constituent and is generally stored in the form of starch.

Incorrect- meiosis result in the production of multiple haploid cells that have no geneticvariation.B. Incorrect- Meiosis produces haploid cells that are unique as a result of independentassortment and crossing over.C. Correct-meiosis forms diploid cells with high levels of genetic variation that divide andgrow into a new Organism.D. Correct- meiosis has multiple divisions that uses independent assortment and crossingover to produce diploid cells.
The correct answer is B. Incorrect- Meiosis produces haploid cells that are unique as a result of independent assortment and crossing over. Meiosis is a special kind of cell division that has two cycles. As a result, chromosome load is reduced by half. Thus, diploid cells entering meioisis are converted in haploid cells. Although it is true that emergent cells from meiosisi will have a unique genetic configuration.

Data about immigration and emigration of individuals of a species' population are helpful to determine how big a population is in each space of its distribution since accounting for how many individuals left that group of individuals, and how many come to it, is useful to address if the population of a particular place is in an ecological equilibrium or not. This leads us to consider that the correct answer is the third one: C. population of a species. We can see an example of this in the following picture about migratory patterns of some bird species:
Nervous coordination transfers nerve impulse from one cell to another. Which option shows site for binding of chemicals involved in chemical synapse?
Nervous coordination transfers nerve impulse from one cell to another. Option 3 shows site for binding of chemicals involved in chemical synapse.
What is synapse?
The places of contact between neurons known as synapses are where information is transferred from one neuron to the next. Presynaptic neuron, synaptic cleft, and postsynaptic neuron are the three components of synapses, which most frequently occur between axons and dendrites.
One neuron releases neurotransmitter molecule into a tiny area (the synaptic cleft that is showed in 3) that is close to another neuron at a chemical synapse. Synaptic vesicles, which house the neurotransmitters, are tiny sacs that are then exocytotic ally discharged into the synaptic cleft. These molecules subsequently attach to the postsynaptic cell's neurotransmitter receptors. Finally, the action of the neurotransmitter is terminated by clearing the neurotransmitters from the synapse by one of several possible processes, such as enzymatic breakdown or re-uptake by certain transporters on the presynaptic cell or on neighbouring neuroglia.
Hence the correct option is 3 as shown in the figure

A person walks from rest to 5.20 meters/second in 10.4 seconds. What is the person's acceleration?
The acceleration of the person in 10.4 seconds will be 0.5 m/s².
How is acceleration and force related to each other?Force is defined as the product of mass of the body and the acceleration with which it is moving. Mathematically -
F = ma
Acceleration and force are related as we can write -
a = F/m
Acceleration is a vector quantity. In the three dimensional coordinate system, the acceleration vector can be resolved as -
[a] = F[x]/m + F[y]/m + F[z]/m
Given is a person who walks from rest to 5.20 m/s in 10.4 s.
We can write -
[u] = 0 m/s
[v] = 5.20 m/s
[Δt] = 10.4 s
Substituting the values in the formula -
a = (v - u)/[Δt]
a = 5.20/10.40
a = 0.5 m/s²
Acceleration will be 0.5 m/s².
Therefore, the acceleration of the person in 10.4 seconds will be 0.5 m/s².

Salt is everywhere. It’s in our pantries and on our kitchen tables. It is present in most foods we eat and some beverages we drink. It is essential for our bodies to function properly. However, it also can be dangerous, or in some cases even deadly. Recently a mother in South Carolina made headlines for killing her 17-month old daughter—using just a teaspoon of salt. For many the reaction to the story was not only shock but questions about how that was even possible. “Salt poisoning is a real thing,” says Sherrie Pace with the Utah Poison Control Center. “There are dangerous salt ingestion practices demonstrated on the Internet that some people will follow, and they don’t understand the risk”

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.

fatty acid tails
Fatty acid tails makes lipids/fats hydrophobic and not mix with water.
What is hydrophobic interaction?Hydrophobic interactions describe the relations between water and hydrophobes (low water-soluble molecules).
Hydrophobes are nonpolar molecules and usually have a long chain of carbons that do not interact with water molecules. The mixing of fat and water is a good example of this particular interaction.
Liquid water is held together by hydrogen bonds. (Liquid water has fewer hydrogen bonds than ice.) Oils and fats not have any polar part and so for them to dissolve in water they would have to break some of water's hydrogen bonds.
Thus, the fatty tails are hydrophobic in nature composed of hydrocarbon chains that are uncharged hence do not interact with water.

Male fiddler crabs are more busy at night than in the morning because they are looking for females to interact with.
What makes male Fiddler crabs want to attract females?Males wave their extended claw in the direction of women to entice them to have physical contact. When a female is ready for physical contact, she will emerge from her burrow and stroll among the waving men (her ovaries are ripe). Before choosing one as her partner, she visits other males (up to 24).
During a visit, the female approaches the male immediately, follows him into his burrow, stays there for a short while, and then emerges to carry on with her exploration.
The male emerges and gathers sand to block the burrow entrance five minutes after the female accepts him as her spouse. The woman then disappears into thin air.
