Explanation:
Both microscopy and motility agar are used to confirm microbial mobility. Research techniques involving microscopic determination of mobility and explain why both microscopy and motility agar are required to determine motility in some microbes.
Answer:
One allows microbe to move in the medium and the other allows to see it.
Explanation:
Both microscopy and motility agar are required to determine motility in some microbes because both substances helps to find out the mobility in the microbes. Motility agar is the medium that allows microbes to swim if they have flagella in their body while on the other hand, microscope is used to see the movement of microbes in motility agar. Microbes are small creature which can't be seen through naked eyes so we used microscope for it.

A. True
B. False
Answer: Hi there I think That I can help You!!!
The cell membrane contains a phospholipid bilayer, but the terms are not interchangeable. Part of the cell membrane is a phospholipid bilayer, made of two layers of phospholipid molecules. However, the cell membrane also contains other macromolecules like membrane proteins, and carbohydrates.
Explanation: So the correct answer is TRUE! don't forget to ate 5 stars and give brainlist!
The statement "the cell membrane consists of one layer of phospholipids" is absolutely false.
What is a Cell membrane?A Cell membrane may be defined as a type of biological membrane that significantly separates the interior components of the cells from the external environment. It also provides protection to the cell as well as other cell organelles.
A cell membrane is made up of a phospholipid bilayer. This illustrates that the two layers of phospholipid molecules are utilized in order to make an effective cell membrane.
It acts as selectively permeable in nature. The head or polar region of phospholipid is hydrophilic while the non-polar tail is hydrophobic in nature.
Therefore, the statement "the cell membrane consists of one layer of phospholipids" is absolutely false.

g In transcription, the 3'-hydroxyl group of the growing RNA strand: Group of answer choices NONE OF THESE binds to the 5' ribose. attacks the outermost phosphorous group of the incoming nucleotide. ALL OF THESE attacks the 5' hydrogen of the incoming nucleotide. interacts with a positively charged metal ion in the active site.
Answer:
attacks the outermost phosphorous group of the incoming nucleotide.
Explanation:
Transcription is the biological process where RNA is formed. As you may already know, RNA is an extremely important nucleic acid for genetic processes and the production of proteins. The transcription has three steps that are called start, elongation and end. In the elongation phase, the RNA strand is growing, at this time, RNA polymerase, which is the enzyme responsible for RNA elaboration, places the nucleotides, in the RNA strand, in the 5' - 3' direction. This enzyme causes the hydroxyl, which makes up the nucleotide at the 3' end of the forming RNA, to attack the phosphorus present in the incoming ribonucleotide.
Alleles are described as ____________________. homologous chromosomes homologous chromosomes alternate versions of a gene alternate versions of a gene alternate phenotypes alternate phenotypes environmental factors that affect gene expression
Answer:
The correct answer is - alternate versions of a gene.
Explanation:
In a cell, if there are two copies of each chromosome, these are called homologous chromosomes, one come from the father and the other comes from the mother, which helps in promoting the variety and stability of a species.
Different or alternate versions of genes are possible that can result in two phenotypes for the same trait, these alternate versions called alleles. Alleles can be dominant and recessive.
What is the rapid change in a membrane's potential caused by the depolarization of a neuron?
Answer:
During depolarization, the membrane potential rapidly shifts from negative to positive. As the sodium ions rush back into the cell, they add positive charge to the cell interior, and change the membrane potential from negative to positive.

Describe the processes that turn metamorphic rock into igneous rock and the energy that powers the processes.
So, we know that a metamorphic rock is either an igneous or a sedimentary rock that are exposed to intense heat and pressure.
But when the metamorphic rock is thrusted deep underground through subduction, it will again be subjected to intense heat. This can cause it to melt, turning it into a magma. When the magma cools down, it again becomes an igneous rock and the rock cycle continues.

A segment of a DNA molecule has the base sequence ATGAAC. Write a shorthand structure for this segment and for its complementary strand, using the symbols D for deoxyribose and P for phosphate.
Answer: See attached picture.
Explanation:
DNA or deoxyribonucleic acid is the name for the molecule that contains the genetic information in all living things. This molecule consists of two strands that wind around each other to form a double helix structure.
The basic unit of nucleic acids are called nucleotides, which are organic molecules formed by the covalent bonding of a nucleoside (a pentose which is a type of sugar and a nitrogenous base) and a phosphate group. So each nucleotide is made up of a pentose sugar called deoxyribose, a nitrogenous base which can be adenine (A), thymine (T), cytosine (C) or guanine (G) and a phosphate group.
What distinguishes one polynucleotide from another is the nitrogenous base, and thus the sequence of DNA is specified by naming only the sequence of its bases. The sequential arrangement of these four bases along the chain is what encodes the genetic information, following the following criterion of complementarity: A-T and G-C. So the sequence of these bases along the chain is what encodes the instructions for forming proteins and RNA molecules. In living organisms, DNA occurs as a double strand of nucleotides, in which the two strands are linked together by connections called hydrogen bridges.
The chemical convention of naming the carbon atoms in the pentose nucleotide pentose numerically confers the names 5' end and 3' end ("five prime end" and "three prime end" respectively). The 5'-end designates the end of a DNA strand that coincides with the phosphate group of the fifth carbon of the respective terminal deoxyribose. A phosphate group attached to the 5'-end allows the ligation of two nucleotides; for example, the covalent bonding of the 5'-phosphate group to the 3'-hydroxyl group of another nucleotide, to form a phosphodiester bond.

Is human reproduction controlled by the nervous system? True or false.
Answer:
True.
Explanation:
The enzyme dihydrofolate reductase (DHFR) normally resides in the cytosol, and it can be imported into mitochondria by appending a mitochondrial signal sequence. However, when this modified DHFR is incubated with methotrexate, which is a substrate analog that binds tightly to the active site, the modified DHFR is no longer imported. Propose an explanation for this finding.
Required:
a. Consider a transmembrane protein that spans the inner nuclear membrane. Suggest a pathway by which such a protein could reach its destination.
b. Clathrin can assemble with multiple types of adaptors to create coated vesicles. Explain why this multiplicity of adaptors is useful to the cell
Answer:
Within the mitochondria, the import takes place post-translationally. The imported protein must be in an unfolded condition so that it can go through the mitochondria's import machinery. In the existence of methotrexate, the bound DHFR moiety remains in the folded state, and thus, stays on the surface of mitochondria.
It is witnessed that the presequence must be of the length of 55 amino acids to cover both the membranes of mitochondria and must be of about sixty amino acids length to associate with the mhsp70. If the presequence of this methotrexate bound DHFR is of seventy-five amino acids in length, it can associate with mhsp70 within the matrix, to initiate the ATP reliant import within the mitochondria. Due to the presence of various endocytic and intracellular sorting signals, multiple adaptors are essential.

Question 29 (3 points)
Predict a change in the Earth's surface or effect observed at each of the following for
1 point each:
- TRANSFORM BOUNDARY
- DIVERGENT BOUNDARY
- CONVERGENT BOUNDARY
Answer:
Divergent boundaries occur along spreading centers where plates are moving apart and new crust is created by magma pushing up from the mantle. Picture two giant conveyor belts, facing each other but slowly moving in opposite directions as they transport newly formed oceanic crust away from the ridge crest.
Perhaps the best known of the divergent boundaries is the Mid-Atlantic Ridge. This submerged mountain range, which extends from the Arctic Ocean to beyond the southern tip of Africa, is but one segment of the global mid-ocean ridge system that encircles the Earth. The rate of spreading along the Mid-Atlantic Ridge averages about 2.5 centimeters per year (cm/yr), or 25 km in a million years. This rate may seem slow by human standards, but because this process has been going on for millions of years, it has resulted in plate movement of thousands of kilometers. Seafloor spreading over the past 100 to 200 million years has caused the Atlantic Ocean to grow from a tiny inlet of water between the continents of Europe, Africa, and the Americas into the vast ocean that exists today.
