One of the reasons you might struggle to lift a heavy object with your arm fully extended is because:_______.
Answer:
the overlapping decreases between the thin and thick filaments.
Explanation:
When w extend our hand or arm to the full and try to lift any heavy object, we are unable to lift the object inspite of applying all our force. We struggle hard to lift the object with our fully extended arm because when we extend our arm fully it decreases the overlapping of our thin and the thick filaments of our muscles which makes it difficult to lift. In other words, the resting length of our arm is the optimal length to generate force.

What is a vein in rock?
Answer:
Vein, in geology, ore body that is disseminated within definite boundaries in unwanted rock or minerals (gangue). The term, as used by geologists, is nearly synonymous with the term lode, as used by miners. There are two distinct types: fissure veins and ladder veins.
Explanation:
Material deposits known as geological veins are created when an existing rock fracture is filled with a new mineral.
How rock veins are formed?
They are fascinating to planetary scientists because they frequently reveal information about historical water flow. For instance, a lot of rocks have natural pores.
A vein in geology is a distinctive sheet-like body of mineral crystals embedded into a rock. When precipitation occurs, mineral components that are transported by an aqueous solution within the rock mass are deposited as veins.
Therefore, it is thought that aqueous solutions carrying different elements migrate through rock fissures and deposit their load onto the fissure walls when vein deposits occur, rising water that is hot.

tRNA molecules bring a specific ________________ to the ribosome, according to the ______________. *
2 points
protein, mRNA anti-codon
protein, tRNA codon
amino acid, tRNA anti-codon
amino acid, mRNA codon
Answer:
tRNA molecules bring a specific amino acid to the ribosome, according to the mRNA codon.
Explanation:
In the context of protein synthesis, an mRNA molecule contains the specific codons that encode the amino acids that will be part of the protein. The tRNA is in charge of bringing the amino acids to the ribosome, according to the specific information of the mRNA codons.
The function of tRNA depends on the complementarity that exists between the mRNA codon and the anti-codon tRNA, in such a way that :
The pattern in the amino acid sequence of a protein is indicated by mRNA tRNA has a complementary anticodon, so it will only bring the specific amino acid that the codon encodes.In general terms, each mRNA molecule possesses the genetic code that indicates the amino acid sequence of a protein, and tRNA helps bring those amino acids to the ribosome for synthesis to occur.
What stages of replication do both cycles have in common? Describe the virion action at each of these stages.
Answer:
Attachment, Penetration and Replication
Explanation:
A bacteriophage is a virus that attacks bacterial cells. The lytic and lysogenic cycles are two methods of viral replication. In the lytic cycle, the virions produced are released from the host cell whereas in the lysogenic cycle, viral nucleic material are incorporated into host nucleic material and are copied to daughter cells when the host cell reproduces. The common steps in both cycles are given below:
1 Attachment – in this step, the bacteriophage attaches itself to the surface of the host cell so as to insert its DNA into the host cell.
2. Penetration – the virus inserts its DNA into the host cell by penetrating the cell membrane of the host cell.
3. Replication – the viral nucleic material is replicated using the host cell's replication mechanism.
The stages of replication is Attachment, Penetration and Replication
The following information should be considered:
A bacteriophage means the virus that attacks bacterial cells. The lytic and lysogenic cycles comrpise of two methods of viral replication.

Why were some of Schwann and Schleiden’s ideas about cells incorrect
Answer:
One of Schwann and Schleiden’s ideas was that cells were originated by spontaneous generation, which was later rejected by Virchow.
Explanation:
Schwann studied animal tissues, and by observing them, he concluded that tissues were made of cells.
Simultaneously, Schleiden arrives at the same conclusion when studying vegetable tissues.
Around 1830, they met and together proposed the first cell theory. The theory stated that:
Every living being is made of cells.Cell is the basic unit of life. Cells are originated by spontaneous generation.Virchow, who studied human tissues, during his observations sow the cell in its dividing process. He then proposed that cells were not originated from spontaneous generation, but they were the product of other pre-existing cells and were originated by cellular division. He rejected the third state of Schwann and Schleiden’s ideas.
How many cycles of β oxidation are required for the complete oxidation of activated oleic acid, 18:1(9)?
Answer:
The answer is "8 beta-oxidation cycles".
Explanation:
Please find the complete question in the attached file.
In this complete oxidation of active oleic acid 18:1(Δ9), 8 beta-oxidation cycles are required. Oleic acid is saturated fat, 9 to 10-carbohydrate fatty acid. Its double bonding is cis-focused. Its cycles for beta-oxidation required to oxidize an active oleic acid fully are 8.
It's initial two fatty acids are removed by oxidation in β - oxidation from the initial two carbon atoms. The recently formed carbon units are made up of creating temporary A molecules (acetyl- CoA). That cycle for oxidative begins with both the coffee grounds terminals of the fat lactone chain.

Yellowstone National Park there are rocks formed that are both extrusive and intrusive igneous rocks. It is important to note that the main difference between them is _________.
Question 6 options:
How they formed; intrusive rocks formed from lava and extrusive rocks are form from magma
How they formed; extrusive rocks formed from lava and intrusive rocks formed from magma
Where they are found; extrusive rocks are only found above ground
Where they are found; intrusive rocks are only found above ground
Answer:
The correct answer is - Where they are found; extrusive rocks are only found above ground
Explanation:
Intrusive and extrusive rocks are the two formed in Yellowstone natIonal park but there is how and where they formed that makes them different from one another. they both are igneous rocks.
The major difference between extrusive rocks and intrusive rocks is that extrusive rocks are formed on the surface or above the earth's surface from the lava that is magma thurst out from underground. Intrusive rocks are formed within the crust from the magma after cooling down and solidify.

If A Plant Cell Were A House...
Cytoplasm
Vacuole
The Cytoplasm
would be the carpeting. The Cytoplasm is the goo that all the organelles reside in, and all the furniture and stuff in the house kind of sit there in the carpeting.
The vacuole would
be the closets and pantries. The vacuole holds random things that the cell needs, and closets and pantries can hold anything you feel like putting in them, like food or clothes.
Lysosome
Mitochondrion
The mitochondrion would be the kitchen. It produces energy for the cell to use, and the kitchen produces food, energy for humans.
Nucleus
Endoplasmic Reticulum
Rough
The nucleus would be my mom. The nucleus controls the cell, and my mom controls my house.
Ribosomes
The Smooth ER would be just plain hallways. The ER is a vast network of tubing that things the cell needs travel down.
The Rough ER would be hallways filled with cattle. This wouldn't be a very good example, because it isn't a very vast network. A lot of people travel down them, though! The Rough ER is like smooth, except with ribosomes.
If you had a herd of cattle in your yard, it would be them. If not, just the kitchen, like the Mitochondrion. Ribosomes synthesize proteins, and cattle make milk, which is full of protein. Also, in the kitchen you can make proteins with different types of dairy, like cheese or milk.
Smooth
Lysosome
Golgi (apparatus)
The Lysosome would be the trashcans, the recycle, and the compost. The Lysosome kills bacteria and holds it in plus other waste, and we dispose of our waste by putting it in one of the above options.
The Golgi (apparatus) would be my dad. The Golgi sorts and packages macromolecules to get them ready to transport. My dad does the same sort of thing, he's in charge of kind of organizing/sorting things around the house.
Cell Membrane
The Cell Membrane would be
the doors and the screens (on the windows). The cell membrane is a semi-permeable barrier, meaning that some things can get through and some can't. For example, only people who have the right key can open the door. Also, with the screens, air can get in, but flies and bees can't.
Chloroplast
Cell Wall
The Chloroplasts would be solar panels, if you had any, or houseplants if not. The Chloroplasts convert sunlight into energy, and both houseplants and solar panels do this same job.
If a cell were a house,
the walls, floors, and ceiling would be the cell wall because they keep everything in the house inside, just like the cell wall keeps all the organelles inside the cell.

Which is most likely to be the original, unlabeled carbohydrate?
Answer:
lactose
Explanation:
Lactose is a disaccharide sugar made up of glucose and galactose monosaccharide subunits. In lactose, galactose and glucose molecules form a covalent glycosidic bond denoted as an (β-1→4) glycosidic bond. Lactase is an enzyme that hydrolyzes lactose into glucose and galactose, which can be then absorbed into the bloodstream by the cells lining the small intestine. In an alkaline solution, lactose may also isomerize to generate a mixture of lactulose (20-30%) and lactose (70-80%).

Most species of deer are known to eat many different types of plants. Other than being herbivores, identify the category of species that explains how deer are very adaptable to new environments.
Answer:
they are invasive species
Explanation:
Invasive species can be defined as a category of non-indigenous species that may cause environmental harm. Invasive species have a high fecundity rate, an important dispersal capacity, highly plastic phenotypes, general habitat preferences, ability to circumvent biological controls (i.e., competitors, predators, diseases), etc. In consequence, these features become invasive species practically impossible to eliminate after introduction into a certain area and highly adaptable to new environmental conditions.
The category of species that describes how most species of deer can adapt to new environments is: invasive species.
Note the following about Invasive species:
Invasive species are usually non-native species in a new environment.They have high fecundity rate, meaning they reproduce faster.They have variety of food they can become adapted to feeding on.They have high survival rate.They can invade an habitat and disrupt the ecosystem.They are pretty difficult to control.Most species of deer is are typical examples of invasive species.
Therefore, the category of species that describes how most species of deer can adapt to new environments is: invasive species.

What causes this change in fur color?
A new microorganism is isolated from a lake and is placed into a solution of KCl. The voltage difference across its membrane is measured at 120 mV. How much energy is required to move a proton from the negative side of the membrane to the positive side?
Answer: [tex]\Delta U=[/tex] 1.922x10⁻²⁰ Joules
Explanation: Electric Potential Energy (U) is the energy a charged object has due to its location in an electric field and it will only exist with the object is charged.
Voltage or Electric Potential Difference (V) is external work done to move a charge from one point to another in a electric field.
These terms have a relationship, which is given by:
[tex]\Delta U=q\Delta V[/tex]
where
q is the charge
Proton is positive and has a charge of 1.6x10⁻¹⁹C.
Unit for potential energy is Joule (J). The relation between mV and J is
1mV = 10⁻³J
Then:
V = 120x10⁻³
V = 0.12
So, for a proton to move from the negative side of a membrane to the positive:
[tex]\Delta U=q\Delta V[/tex]
[tex]\Delta U=1.6.10^{-19}.0.12[/tex]
[tex]\Delta U[/tex] = 1.922 x 10⁻²⁰
Energy necessary to transport a proton from negative side of the membrane to the positive is 1.922 x 10⁻²⁰J.
