Which one of these can be rearranged into a type of flower? A. FSNWOLRUE B. LBANEQUT C. NRABE D. VLEBQA
Answer:
flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to affect reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross pollination or allow selfing (fusion of sperm and egg from the same flower) when self pollination occurs.
Pollination have two types which is self-pollination and cross-pollination. Self-pollination happened when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happened in flowers where the stamen and carpel mature at the same time, and are positioned so that the pollen can land on the flower’s stigma. This pollination does not require an investment from the plant to provide nectar and pollen as food for pollinators.[1]
Some flowers produce diaspores without fertilization (parthenocarpy). Flowers contain sporangia and are the site where gametophytes develop. Many flowers have evolved to be attractive to animals, so as to cause them to be vectors for the transfer of pollen. After fertilization, the ovary of the flower develops into fruit containing seeds.
In addition to facilitating the reproduction of flowering plants, flowers have long been admired and used by humans to bring beauty to their environment, and also as objects of romance, ritual, religion, medicine and as a source of food

What fraction of offspring of the cross AabbDd x AaBbDd are expected to have the
same phenotype as either one or the other of their parents assumingthat all three
genes are on different chromosomes?
A. 18/64
B. 24/64
C. 9/64
D. 36/64
E. none of the above
Answer: E. none of the above
Explanation:
given data:
AabbDd x AaBbDd
For gene A, there will be cross of Aa X Aa. The probability of having a phenotype, that is either AA or aa is 2/4 = 1/2
For gene B, there will be cross of Bb X BB. The probability of having a phenotype, that is BB is 1/4
For gene D, there will be cross of Dd X Dd The probability of having a phenotype, that is either DD or dd is 2/4 = 1/2.
Hence, the probability of the off spring having all the genes.
= 1/2 * 1/4 * 1/2
= 1/16
Calculate the volume of 1 M NaOH needed to prepare 12.0 mL of a 0.10-M solution. Prepare this solution. (Refer to the Dilutions section in the Background.)
Answer:
1.2 mL
Explanation:
This is a problem of simple dilution. The dilution principle simply agrees that the number of moles before dilution must be equal to the number of moles after dilution.
Recall that: number of moles = mass/molar mass or molarity x volume.
Hence, for the dilution principle:
initial molarity x initial volume = final molarity x final volume.
In this case, initial molarity of NaOH = 1 M, initial volume = ?, final molarity = 0.1 M, final volume = 12.0 mL.
Initial volume = final molarity x final volume/initial molarity
= 0.1 x 12/1 = 1.2 mL
It thus means that 1.2 mL of 1 M NaOH would be taken and then diluted up to 12.0 mL mark by the addition of distilled water in order to produce 12.0 mL, 0.10 M NaOH solution.
The volume should be 1.2 mL
What is the dilution principle?It should be agreed that the no of moles prior to the dilution should be equivalent to the no of moles after dilution
We know that
number of moles = mass / molar mass or molarity x volume.
According to the above principle, we can say that
initial molarity x initial volume = final molarity x final volume.
So,
initial molarity of NaOH = 1 M,
initial volume = ?,
final molarity = 0.1 M,
And, final volume = 12.0 mL.
So,
Initial volume = final molarity x final volume/initial molarity
= 0.1 x 12/1
= 1.2 mL
Hence, The volume should be 1.2 mL

Jamie has decided to breed rabbits. Her male rabbit is white, while her female rabbit is black. They produce a litter of black and white spotted rabbits. Assuming that coat color is controlled by only 1 gene, is this codominance or incomplete dominance? Justify your answer.+
The answer would be CODOMINANCE because codominance is when 2 genotypes show up at the same time on an object, where incomplete dominance is when 2 different genotypes combine and create a whole new phenotype
Animals are multi-celled consumers that take food into their body, where they digest it and absorb the released nutrients. An animal develops from an embryo (an early developmental stage) to an adult. Animal life began in the sea, and the Earth’s oceans still hold the greatest store of animal diversity. The majority of animals are invertebrates, meaning they do not have a backbone.

Explanation:
5. You are attempting to view a Gram-stained slide in your microscope. You can focus on the bacteria perfectly using the 10X objective, but you cannot focus on them at all under 40X or 100X no matter how much you adjust it (the entire range of the focus knobs will not allow you to get the slide in focus). Assuming your microscope is fully functional, what is the most likely problem? (1pt)
Answer:
See the answer below
Explanation:
When an object on a sample slide can be perfectly focused at lower objective but cannot be focused at higher objectives, the problem can be attributed to two factors depending on the size of the objective:
1. At 40X objective, the most likely problem would be that the object on the sample slide is not in the center of the field. Adjusting the slide until the object on it is at the center of the field would likely solve this problem.
2. At 100X objective, the problem could also be that the object on the slide is not at the center of the field, could be that there is no immersion oil on the slide or a combination of the two factors. Dropping an immersion oil on the slide and adjusting the slide to bring the object on it to the center would solve this problem.

How does a cell normally make a thermodynamically disfavored reaction go forward?
Answer:
by producing enzymes that catalyze non-spontaneous reactions
Explanation:
Thermodynamically disfavored reactions can be referred to as nonspontaneous reactions (ΔG > 0). An enzyme is a catalyst molecule (generally proteins) capable of converting a non-spontaneous reaction into a spontaneous reaction and improve the speed of one chemical reaction in the cell. Enzymes are capable of reducing the energy of the transition state of a chemical reaction (rate of the reaction), thereby modifying the kinetics of a reaction.

Answer:
1. It depends on the DNA region that has been affected by the chromosome rearrangement
2.Translocations
3.Translocations
4. Inversions
5. Duplications
6. Deletions
Explanation:
A translocation is a chromosome rearrangement where a chromosome fragment breaks off and the resulting portion attaches to another genome region. An inversion occurs when a single chromosome fragment is reversed end to end, thereby also producing a chromosome rearrangement. Inversions can be classified into pericentric (include the centromere) and paracentric (not include the centromere). Finally, chromosome duplications and chromosome deletions are opposite rearrangements where chromosome portions are copied in tandem and eliminated, respectively.
The regulatory genes that encode for the repressor protein are always being transcribed; it is the presence or absence of the lactose molecule that controls whether the operon is on or off.
a) true
b) false
Answer:
The answer is A.
Explanation:
The lac repressor protein can prevent or let the transcription and production of the operan. When there is lactose not present in the body, the lac repressor protein prevents the production of the operan by RNA polymerase but when lactose is present, it let's the operan to get produced . So the answer is yes, the presence of the lactose molecule controls whether the operon is on or off.

State the unique characteristics of epithelial tissue.
Answer:
Characteristics of epithelium tissue
1.Polarity- Epithelium is arranged so there is one free surface (apical surface) and one attached surface (basal surface)
2.Cellular nature– Cells in epithelium fit closely together side by side and sometimes atop each other to form sheets of cells. These sheets are held together by specialized junctions.
3.Supported by connective tissue– Attachment to a layer of connective tissue at the basal surface forms a layer called the basement membrane, an adhesive layer formed by secretions from the epithelial cells and the connective tissue cells.
4.Avascular– Epithelium typically lacks its own blood supply.
5.Regeneration– Epithelium cells can regenerate if proper nourished.
6.Absence of nerves (except for a few axons in the deeper layers)
Classification scheme of epithelial tissue:
Typically epithelial tissue is classified on the basis of arrangement and shape of cells. For naming the tissue types, the arrangement of the cells is stated first, then the shape, and is followed by “epithelium” to complete the naming. For example; Simple Squamous Epithelium.

Summarizing Activities and Ideas
How did the lab activities help you answer the lesson
question, "How do atmospheric conditions influence
weather patterns?" What did you learn from conducting
this lab?
Answer:
Air pressure is influenced by the differences between hotter and cooler pockets of air, or fronts. ... When atmospheric pressure is low, air is pushed down toward the surface, meaning rain and moisture don't accumulate. This often also leads to high humidity near the surface of the Earth, where people experience weather.
Explanation:
Answer:
Sample Response: In the lab, I discovered the air pressure, air temperature, and relative humidity conditions that create snow, rain, thunderstorms, fog, and clear skies. I learned that low-pressure areas usually experience snowy, rainy, and stormy weather, and that high-pressure areas usually experience either foggy or sunny weather. Knowing how these atmospheric conditions influence weather help weather forecasters predict weather patterns through maps and other information.

Similarities between plasmolysis and haemolysis
Answer:
The main similarity between plasmolysis and hemolysis is that they both involve the destruction of a cell.
Explanation:
Similarities between plasmolysis and hemolysis are their involvement in the termination of the cell.
What is plasmolysis?The live protoplasm violently separates from the cell wall as a result of the loss of turgor. The vacuole is primarily responsible for the plasmolytic process.
Hemolysis is Plant cells subjected to hyperosmotic stress frequently exhibit plasmolysis as a reaction. T Living plant cells exhibit plasmolysis, which is reversible deplasmolysis.
Hemolysis is a process in which red blood cells are destructed. It is a process of rapturing of blood cells. It happens due to improper needle size and this is a disease, in which blue and white tinged happen in the eyes.
Therefore, both plasmolysis and hemolysis are subjected to the death of cells in the body.

An immune response to a tissue graft will differ from an immune response to a bacterium because ________.
Answer:
Explanation:
They will differ because MHC molecules of the donor may stimulate rejection of the graft tissue as opposed to a receiver rejecting it in an immune response. That is because the MHC molecules are a group of genes that code for proteins found on the surfaces of cells that help the immune system recognize foreign substances and the surfaces are what is being transplanted during a tissue graft, meaning they are the ones that will ultimately reject the tissue graft operation.
When comparing a cell just before the first meiotic division with another cell of the same organism that is ready to start mitosis, we can correctly conclude that both cells present: * Select the correct option (s) I. Equal amount of DNA. II. Equal amount of chromatids on your chromosomes. III. Equal number of chromosomes.
Answer:
III. Equal number of chromosomes.
Explanation:
Comparison between two cells, one cell just before first meiotic division and other cell ready to start mitosis is that both the cells have equal number of chromosomes.
Both the cells have an equal number of chromosomes that is 2n (diploid), where n is 23 and total chromosomes are 46 in each cell but at the meiosis at the end meiosis produces four haploid (n) daughter cells and mitosis produces two diploid (2n) cells.
Hence, the correct answer is "III. Equal number of chromosomes.".
