When the object is placed on the slide and is in focus for each objective, the space between the slide and the objective lens gets reduce, so the microscope shouldn't be set exact at the edge.
As the objective magnification increases, the working space also increases. Therefore, you need to change it to a higher power target.
Change the focus knob to increase the stage as you look at the objective lens and stage from the side. Without permitting the objective to make contact with the coverslip, increase it as high as it can go. The sample's focus or the condenser and light intensity might need to be arranged.
Thus the accurate way to focus is that adjustments need to be made effectively and smoothly

What is signal hypothesis occuring in endoplasmic reticulum?
Answer:
What happen in endoplasmic reticulum is the process of protein synthesis, which happens in the rough endoplasmic reticulum. Meanwhile, what happens to the smooth endoplasmic reticulum plays a role in metabolic processes of lipid synthesis, carbohydrate metabolism, calcium ion storage, and detoxification of drugs and toxins.
Explanation:
Endoplasmic reticulum is an organelle (a kind of organ) that is part of eukaryotic cells and has a very important role. The function of the endoplasmic reticulum is to produce, process, as well as transport transmembrane proteins and lipids for cell membranes and various other cell components.
The endoplasmic reticulum consists of the nuclear envelope and the periphery of the reticulum. The peripheral reticulum is divided into smooth endoplasmic reticulum and rough endoplasmic reticulum.
What happens in the rough endoplasmic reticulum is the process of protein synthesis, namely the process of protein formation through transcription and translation mechanisms. Meanwhile, what occurs in the smooth endoplasmic reticulum or smooth endoplasmic reticulum plays a role in the metabolic processes of lipid synthesis, carbohydrate metabolism, calcium ion storage, and detoxification of drugs and toxins.

If the haploid number of an organism is 5, then each dividing diploid cell will have how many chromatids at mitotic metaphase?.
20 diploids chromatids will be present at mitotic metaphase.
What are haploid and diploid chromatids?Cells that enter meiosis II are cells that were produced in meiosis I. These cells are haploid and have only one chromosome from each homologous pair, but their chromosomes still consist of two sister chromatids. In meiosis II, sister chromatids separate to form haploid cells with non-overlapping chromosomes.
Two separate sets of chromosomes (daughter chromosomes) are formed by separating pairs of chromatids during cell division (from anaphase of mitosis and anaphase of meiosis II). A term for cells or organisms of which there is only one set (n).
A cell that contains two copies of each chromosome is called a "diploid cell." Human cells are diploid: It contains 46 chromosomes, 22 pairs of autosomes, and 1 pair of sex chromosomes.
Haploid = 1 chromosome;
Diploid = 1 chromatid
5 haploids = 10 diploids
Chromosomes are duplicating in metaphase,

After observing the untitled card for mitosis: prophase, what did you see in the diagram that led you to believe that it was mitosis: prophase?
The chromosomes were not evenly spaced out that showed in the diagram that led you to believe that it was mitosis: prophase.
What is mitosis?
Cell biology refers to the phase of the cell cycle where replicated chromosomes break into two new nuclei. In the process of cell division known as mitosis, genetically identical cells with a fixed number of chromosomes are created. As a result, equational division is another name for mitosis.
The prophase is the first stage of mitosis, which splits the duplicated genetic material contained in a parent cell's nucleus into two identical daughter cells. During prophase, the chromatin, a mix of proteins and DNA found in the nucleus, condenses.
Hence the correct answer is the chromosomes were not evenly spaced out.

9.) When a person consumes less food than is required to meet body needs,
glycogen is converted into?
When a person consumes less food than is required to meet body needs, glycogen is converted into glucose.
This stored shape of glucose is made of many connected glucose molecules and is known as glycogen. Whilst the frame needs a quick enhance of energy or while the body isn't always getting glucose from meals, glycogen is broken right down to launch glucose into the bloodstream for use as gasoline for the cells.
As soon as glycogen shops are depleted, your frame runs out of gasoline and you'll start to experience worn-out. Consuming carbohydrates even as you workout will prevent glycogen depletion. For the duration of lower-depth using, the frame clearly uses more energy from the breakdown of muscle triglycerides.
Whilst your body doesn't without delay want glucose from the food you consume for energy, it shops glucose in most cases in your muscle groups and liver as glycogen for later use. Your frame creates glycogen from glucose thru a method referred to as glycogenesis.

A) proton gain
B) electron loss
C) electron gain
D) proton loss
The process that will change a chloride atom into a negative chloride ion will be (C) electron gain.
Chloride ion is the negatively charges ion that forms due to the gain of one electron in the neutral chloride atom. It can also be called anion due to its negative charge. Chloride anion forms an essential electrolyte in the human body that is required for maintaining the osmotic balance.
Electron is a negatively charged sub-atomic particle that makes up an atom. It surrounds the nucleus of the atom giving a cloud like appearance. The charge than an electron carries within it is 1.60 × 10⁻¹⁹ coulombs. The electron can be bound to the atom or occur in free state.

What is friction?Friction is the force that resists relative motion as elements of solid surfaces, fluid layers, and materials slide over each other. There are many types of friction. It is the force that opposes the relative lateral movement of two solid surfaces in contact. This is the force that resists the movement of one solid object over another. Four types of friction: static friction, sliding friction, rolling friction, fluid friction.
Adhesion is the molecular force that occurs when two materials come into close contact and cause friction.
