Answer:
100%
Explanation:
This question involves a single gene coding for flower color in pea plants. The allele for purple flowers (P) are dominant to white flowers (p). This means that purple color will be expressed in a heterozygous state.
According to this question, If two white flowered plants are cross i.e. pp × pp, the following gametes will be produced by each of the parent: p and p. Using these gametes in a punnet square (see attached image), ALL (100%) of the offsprings will be white colored (pp).
Therefore, 100% of the offsprings will be white flowered.
When a cell with 18 chromosomes divides by meiosis, the result would be four daughter cells, each with 9 chromosomes, option(c). This is because meiosis reduces the number of chromosomes in each daughter cell by half.
The best description of the expected daughtercells when a cell with 18 chromosomes divides by meiosis is: The result would be four daughter cells, each with 9 chromosomes. This is because meiosis is a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell. The process of meiosis begins with a parent cell that is diploid, meaning it has two complete sets of chromosomes. During meiosis, this cell undergoes two rounds of division, resulting in four haploid daughter cells, with each containing half the number of chromosomes as the original parent cell. In this case, the original cell has 18 chromosomes, so each of the four daughter cells will end up with 9 chromosomes, option(c).

Question: A cell with 18 chromosomes divides by meiosis. Which of the following statements best describes the expected daughter cells?
a. The result would be two daughter cells, each with 18 chromosomes.
b. The result would be four daughter cells, each with 18 chromosomes.
c. The result would be four daughter cells, each with 9 chromosomes
d. The result would be two daughter cells, each with 9 chromosomes.
Answer: there are four daughter cells. Each daughter cell has different characteristics from the parent

The step-by-step plan for dealing with broken glassware on the floor or lab table has been stated below:
1 tell the person in charge or the teacher
2 make sure u did not get cut
3 get the large pieces and put them into glass waist container
4 get broom or brush weep area and get small pieces depose in same place
5 take a wet wipe and cover area to pick up anything that as missed.
Glassware has been refer to the any laboratory apparatus made of glass. When you are done using a glassware, wipe down the glassware to remove any cleaning solvent. They are often washed with a solvent and particles of the cleaning solvent adheres to the glassware.
A lot of our laboratory apparatus are made of glass e.g beakers, conical flask, measuring cylinders etc. These glassware must be properly cleaned after use.
These particles of the solvent must be wiped to remove these particles of cleaning solvent that could contaminate a sample placed in the glassware.
Therefore, The step-by-step plan for dealing with broken glassware on the floor or lab table has been stated below:
1 tell the person in charge or the teacher
2 make sure u did not get cut.

Treat the cut with antiseptic from the first-aid kit.
Put a bandage over the cut.

3. What is a negative control you should use to rule out alternative explanations for a positive result?
4. In Parts 2 and 4, you measured the diameter of the micronucleus using fluorescence microscopy and electron microscopy. How do the measurements compare? Which of the two types of microscopy above do you believe was most accurate? Why?
Phagocytosis queries are given detailed in the following way
Explanation:
1.Phagocytosis is a process wherein a cell binds to the item it wants to engulf on the cell surface and draws the item inward while engulfing around it.Phagocytosis differs from other methods of endocytosis because it is very specific and depends on the cell being able to bind to the item it wants to engulf by way of cell surface receptors. Phagocytosis won’t happen unless the cell is in physical contact with the particle it wants to engulf.
2.A hypothesis states a presumed relationship between two variables in a way that can be tested with empirical data. ... The cause is called the independent variable; and the effect is called the dependent variable.
Independent and Dependent Variable Examples. In a study to determine whether how long a student sleeps affects test scores, the independent variable is the length of time spent sleeping while the dependent variable is the test score. You want to compare brands of paper towels, to see which holds the most liquid.
3.A negative control is a control group in an experiment that uses a treatment that isn't expected to produce results. A positive control is a control group in an experiment that uses a treatment that is known to produce results.
A negative control is part of a well-designed scientific experiment. The negative control group is a group in which no response is expected. It is the opposite of the positive control, in which a known response is expected.
These two controls, when both are successful, are usually sufficient to eliminate most potential confounding variables: it means that the experiment produces a negative result when a negative result is expected, and a positive result when a positive result is expected.
4.Electron microscopes differ from light microscopes in that they produce an image of a specimen by using a beam of electrons rather than a beam of light. Electrons have much a shorter wavelength than visible light, and this allows electron microscopes to produce higher-resolution images than standard light microscopes.Microscopes are used to produce magnified images. ... light microscopes are used to study living cells and for regular use when relatively low magnification and resolution is enough. electron microscopes provide higher magnifications and higher resolution images but cannot be used to view living cells.
