The complete diagram is shown below in the image representing the stages of meiosis.
Mitosis as well as meiosis are both types of division of the nucleus in the eukaryotic cells. The complete diagram shows that Meiosis comprises of two nuclear divisions which lead to the formation of four nuclei which are generally divided resulting in the creation of four new haploid cells.
The nuclei that are formed by the process of meiosis are not genetically identical unlike mitosis. During Meiosis I, the synapsis of homologous chromosomes occurs, chiasmata formation and crossing over takes place. The sister chromatids also align along the Metaphase plate in tetrads.

What two factors are considered when determining the risk assessment for air pollutants?.
Answers
When determining the risk assessment for air pollutants, two factors that are considered are exposure assessment and hazard assessment.
Exposure Assessment: This involves evaluating the extent and duration of human exposure to air pollutants. It considers factors such as the concentration of pollutants in the air, the duration of exposure, and the frequency of exposure.
Hazard Assessment: This involves assessing the inherent toxicity or harmful effects of the air pollutants. It considers the potential health effects associated with specific pollutants, such as respiratory irritation, cardiovascular problems, cancer risks, or neurotoxicity.

If trypsin were to be placed in an acidic environment, how would it function? How do you know?
Answers
Answer:
If trypsin is in an acidic environment, it will decrease its function, since its optimum pH is 8.
Explanation:
Trypsin is an enzyme responsible for break peptide bonds, thus hydrolyzing proteins into peptides and amino acids. This enzyme is secreted by the pancreas and poured into the duodenum —an alkaline environment— where it acts.
Since the optimal pH for trypsin to fulfill its function is 8, if the enzyme were placed in an acidic environment it would decrease its function. This is because enzymes work under specific pH and temperature conditions, and changes in these conditions affect enzymatic activity.

what are atoms and how are the subatomic particles diagrammed?
Answers
Atoms are the basic building blocks of all matter (solids, liquids, gases and plasma) in the universe. For example, you and I are made entirely of atoms. The device you're using to view this answer is made of atoms.
Within atoms are subatomic particles. These include protons, neutrons and electrons. Protons and neutrons are located within the nucleus of an atom while electrons orbit around the nucleus, arranged in shells (the "outside part" of an atom). Changing the number of subatomic particles there are in an atom can change its properties (ex. what element it represents, how reactive the substance is, etc.)

-Acts as a receptor for gas intake
Answers
Answer:Wide
Explanation:
The image that shows the cambium is indicated by the arrow. The function of the plant structure is to expand the width and height of plants through growth. The correct option is b.
What is cambium?Cambium is a narrow plant membrane found directly beneath the bark of a woody tree or plant. The cambium has numerous purposes. It develops xylem and phloem layers in woody plants, increasing the diameter of the stem.
It also promotes secondary root and stems growth. Secondary phloem and xylem tissue are produced by the vascular cambium. The vascular cambium is a plant tissue located in the stem of a vascular plant between the xylem and the phloem. It also serves as a source of secondary xylem and secondary phloem growth.
Therefore, the correct option is b, expanding the width and height of plants through growth.

No exceptions to the central dogma exist. Rna is always transcribed from dna, and rna is translated to produce proteins. True or false?.
Answers
The above-given statement that 'No exceptions to the central dogma exist. RNA is always transcribed from DNA, and RNA is translated to produce proteins' is false.
The above statement is false because of the process of reverse transcription.
In the field of biology, central dogma can be defined as a process through which mRNA is formed by DNA, under a process named transcription. The mRNA formed then forms proteins under the process referred to as translation.
However, in some organisms, like the retroviruses, the process of reverse transcription was discovered. Reverse transcription is the process by which RNA is converted into DNA which is an exception to the central dogma process. The process of reverse transcription is now being used in genetic engineering due to its various benefits.

Answers
The body composition assessment method that involves the estimation of the 3-dimensional volume of the body through measurement of an individual’s body weight while they are completely submerged under water is Hydrodensitometry.
Hydrodensitometry is based upon the Archimedes principle. It provides information of two components: the fat mass and the fat-free mass. It is also called under-water weighing. This technique is not commonly used, however it is mostly used on athletes.
Body composition assessment is the method to calculate the ratio of fat-to-fat free mass. The composition if assessed to gain knowledge about the fitness of the body.

What characteristic of water helps it cause a mineral, such as halite, to dissolve?.
Answers
(B) the polar nature of the water molecule is the characteristic that helps it cause a mineral, such as halite, to dissolve.
When a bond forms between a metal and a non-metal, ionic compounds are produced. The metal ion always loses electrons during ion production and turns positive, while the non-metal ion gains electrons and turns negative. Chlorine and sodium atoms are split apart by water molecules as halite dissolves in water.
Since it is essentially just a crystal of sodium chloride, halite is also referred to as rock salt. When sodium and chlorine combine to form ions, the resulting Na+ and Cl- ions are separated from one another by water molecules and serve as charge carriers when water is exposed to an electric current.

A. facilitated diffusion
B. active transport
C. filtration
D. Osmosis
Answers
I would assume osmosis, as sodium chloride is just salt and salt travels to water, which is abundant in the egg.
Option D. osmosis is the cellular transport is the teacher demonstrating in the given case.
Osmosis is the flow of water through a semi-permeable membrane from an area of higher water concentration to an area of lower water concentration. When the egg was placed in a solution of vinegar,
vinegar reacts with the eggshell, bubbles surround the egg and dissolve the shell.It is known vinegar is a weak acid diluted with lots of waterWater moves from the vinegar, through the egg’s semi-permeable membrane, into the egg due to osmosis.When the egg was placed in the salt solution that had a higher concentration of water than was inside the egg,
water moves into the egg.The egg will become larger when placed in the salt solution due to the solution’s low salt concentration and sinks in the solution.Thus, the correct answer is - option D. osmosis.

Answer:
A. Active transport requires cell energy while osmosis does not
Explanation:
Active and passive transport are important for living organism as they regulates the entry and exit of molecules and ions in a cell.
Active transport require cell energy in the form of ATP to maintain the right concentrations of ions and molecules in living cells while osmosis is a type of passive transport and doe snot require cell energy this is so because ion concentrations in osmosis remain same both the side of the membrane and do not require cell energy to pump the molecules.

In some science experiments, you are trying to compare the effects that a certain variable may have on the topic of interest. For example, read the following question: What brand of fertilizer makes roses grow the fastest? Let’s say you had three brands that you were using, and we will just call them brands A, B, and C. In an experiment, the different types of fertilizer would be called treatments, because you will be treating roses with each type of fertilizer. Most experiments that have a treatment also have a control, which in this case would be roses that had no fertilizer applied to them. In any experiment you want to eliminate as many variables as possible. In this experiment, the only thing you want to vary is the type of fertilizer. Everything else (sunlight, water, temperature, etc) you hope, will stay the same. Use the information about this example experiment to answer problems 7-10.
