4. Choose the microscopy technique that would best fit the needs of each scenario.
Scenario 1: Scientists are attempting to identify the specific type of leukemia a person has based on cell surface structures. ___
Scenario 2: Researchers are studying chemotaxis in white blood cells. Chemotaxis is the movement of living cells in response to a particular substance. ___
Scenario 3: Cell biologists are interested in measuring the distance between the inner and outer nuclear membranes, and need an instrument capable of producing images where the tiny distance between these two membranes is clear. __
Answer: Scenario 1: SEM
Scenario 2: Light
Scenario 3: TEM
Explanation:
The technique applied to observe and analyze objects that cannot be seen with the bared eye is called the microscopic technique.
1. The technique used will be SEM. A scanning electron microscope (SEM) is used to generate an image on the individual surface with the help of electron lasers.
It is useful in apprehending cell surface fabrication and topography.Therefore, to study the cell surface structure of leukaemia SEM is best.2. The light microscopy technique can be applied to study chemotaxis.
When there will be a movement in the living cell due to response towards chemical then the light microscope can be used to visualise the cells.Therefore to study chemotaxis light microscopy should be employed.3. The transmission electron microscope (TEM) method can be used to know the gap between the inner and outer layers. They are used for observing very thin segments of specimens.
Through the thin fragments, the electron flows easily and the image is produced.Therefore, TEM should be used by scientists to measure the distances.To learn more about the microscopy techniques follow the link:

Is baking soda organic or inorganic explain why?
Answer:
Inorganic
Explanation:
Baking soda can be found as a naturally occurring compound, but is more frequently manufactured from other naturally derived materials, like trona ore. Baking soda can be produced by the reaction of carbon dioxide and soda ash, a naturally occurring mineral. To my knowledge there is not an “organic” baking soda.
a cell is placed in a isotonic solution. How does the cell maintain homeostasis in the environment ?
Answer:
If a cell is placed in an isotonic solution, there will be no net flow of water into or out of the cell, and the cell's volume will remain stable. If the solute concentration outside the cell is the same as inside the cell, and the solutes cannot cross the membrane, then that solution is isotonic to the cell.

Numerous atp and naphtha are produced during light reaction why
Answer: cracking of naphtha. It is important to ensure that the feedstock does not crack to form carbon, which is normally formed at this temperature. This is avoided by passing the gaseous feedstock very quickly and at very low pressure through the pipes which run through the furnace Shale naphtha is obtained by the distillation of oil produced from bituminous shale by destructive distillation. Petroleum naphtha is a name used primarily in the United States for petroleum distillate containing principally aliphatic hydrocarbons and boiling higher than gasoline and lower than kerosene.
Explanation: Light naphtha can refer to either a finished product used as a petrochemical feedstock or a distillation cut commonly called light straight run naphtha. It is composed of pentane and slightly heavier material. In a refinery, light naphtha is often blended directly into gasoline.

Why are there two sets of phases during meiosis, but only one during mitosis? Think about what is different about meiosis and mitosis
Answer correctly or I will report
Answer:
Cells undergoing mitosis just divide once because they are forming two new genetically identical cells where as in meiosis cells require two sets of divisions because they need to make the cell a haploid cell which only has half of the total number of chromosomes.

How does soil erosion affect streams and rivers?
Explanation:
The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
If an oceanic plate and continent plate converge, which plate will sink?
Answer:
When an oceanic and a continental plate collide, eventually the oceanic plate is subducted under the continental plate due to the high density of the oceanic plate. Once again a benioff zone forms where there are shallow intermediate and deep focus earthquakes.

Which refers to the sum of all the forces that act upon an object?
A. net force
B. absolute force
C. balanced force
D. positive force
Answer:
Net force
Explanation:
Net force is the vector sum of forces acting on a particle or body. The net force is a single force that replaces the effect of the original forces on the particle's motion. It gives the particle the same acceleration as all those actual forces together as described by the Newton's second law of motion.

Explain why the legs of cats and grasshoppers are considered analogous.
2. Explain why the legs of cats and flippers of whales are considered homologous.
3. Explain how this diagram shows that cats and whales are more closely related than either is to an insect.
Answer:
2)Homologous Structures Humans Share With Animals
A dolphin's flipper, a bird's wing, a cat's leg, and a human arm are considered homologous structures. ... This structure serves as evidence of having a common ancestor, one that would have had a tail. All mammals share the homologous structure of the vertebrae in common.
3)WHERE IS THE DIAGRAM
Explanation:
A plant cell has a 5%, percent salt concentration. It is placed into a solution
containing a 12%, percent salt concentration.
Explain what will happen to the cell and why?
Answer:
Water in cells moves toward the highest concentration of salt. ... If a higher concentration of salt is placed outside of the cell membrane, the water will leave the cell to bond with it. The loss of water from this movement causes plant cells to shrink and wilt.
Explanation:
When does
transcription
happen?
Answer:
Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins). RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule. Transcription ends in a process called termination.
Explanation:
Transcription Initiation. The first step in transcription is initiation, when the RNA pol binds to the DNA upstream (5′) of the gene at a specialized sequence called a promoter (Figure 2a). In bacteria, promoters are usually composed of three sequence elements, whereas in eukaryotes, there are as many as seven elements ...

Explanation:
Human blood consists of blood groups A, B, and O. However, there is one more blood group, AB, which contains alleles A and B in the same genotype. What is this phenomenon called?
A.
coinheritance
B.
codominance
C.
incomplete dominance
D.
polygenic inheritance
Answer:
B. codominance
Explanation:
because if the placement of the A and B molecules on each cell is controlled by the proteins that are coded by different versions of the same gene, then IA and IB are codominant but both are dominant to Io. If a person receives an IA allele and a IB allele, their blood type is type AB, in which characteristics of both A and B antigens are expressed.

2. the light-dependent reactions and the Calvin cycle.
3. The photosynthesis chemical equation states that the reactants (carbon dioxide, water, and sunlight), yield two products, glucose, and oxygen gas.
4. As in other reactions, NADPH helps carry electrons and protons driven by sunlight into new carbon-carbon bonds, creating sugar molecules. NADPH is often kept at a higher concentration in the cytosol than NADP+, to allow for the easy reduction of small molecules into larger macromolecules.

(A.Instructions
(B.Genes
(C.Recipe
(D. Life manual
Genes of DNA can be read by chemicals and proteins for building that can make cells, tissue, and organs. Therefore, option "B" is correct.
What are genes?
Genes are composed of DNA which is the genetic material. Gene is the functional unit of heredity. Chromosomes are comprised of multiple genes. Genes code for a particular trait. More than one gene can code for a particular trait.
The function of DNA and RNA is controlled by genes. There are more than 3000 genes present. Mutation can occur in genes. Deletion and insertion are some types of mutation genes. Transposomes are called jumping genes. Sickle cell anemia and cystic fibrosis are some examples of gene mutations.
Genes code for the traits such as the color of eyes, height quality of hair, and more.
