Hard structures of corals and shelled organisms are deteriorating because of
1. increasing ocean pH
2. decreasing ocean pH
3. increasing ocean temperature
4. decreasing ocean temperature
Answers
Answer:
The correct answer is - 2. decreasing ocean pH.
Explanation:
Many marine organisms such as corals that have hard calcium carbonate shells or skeletons are deteriorating due to the increase of carbon dioxide levels dissolved in marine water which leads to decreasing pH in seawater.
For example, increasing ocean acidification or decreasing pH level due to increased carbon dioxide has been shown to significantly reduce the ability to maintain their skeleton or hard structure or building again. Due to Co2 dissolving in the water means more hydrogen ions in seawater that leads to the concentration of CO3^2- ions actually decreases.

How do the chromosomes at the end of meiosis i compare with the chromosomes at the end of meiosis ii?
Answers
At the end of meiosis I, each chromosome still consists of two sister chromatids, but the number of chromosomes is reduced by half.
This reduction is due to the separation of homologous chromosomes, which are pulled to opposite poles of the cell during the first division. At the end of meiosis II, the sister chromatids finally separate, resulting in four haploid daughter cells, each containing a single chromosome. So, at the end of meiosis II, the chromosomes are in their haploid form, with only one chromatid per chromosome. In summary, the chromosomes at the end of Meiosis I are still composed of sister chromatids, while the chromosomes at the end of Meiosis II are single chromatids in each of the four haploid cells.

Explain how natural selection is related to individuals and populations.
Answers
Answer: Natural selection applies to both individuals and populations because natural selection is the process of something adapting. An Individual adapts to extreme heat, heavy rain, etc. This individual then has offspring which the adaptation passes off to and to his offspring and so forth. Another way it affects population is by the area in which the population lives. If the individual and other individuals live in the same area, the other individuals are likely to adapt to the environment as well.

Answers
If Bobo Fett were a homozygous dominant (GG), crossing him with a homozygous recessive (gg) would have produced only heterozygous offspring (Gg), making all the puglets black.
On the other hand, if Bobo Fett is heterozygous (Gg), then the crossing with a homozygous recessive (gg) can produce black heterozygous puglets (Gg), and fawn puglets, that are homozygous recessive.
Given that the litter has both colors of puglets, Bobo Fett is heterozygous.

during winter, what factors can reduce the rate of photosynthesis in evergreens such as pine trees? choose all that apply
Answers
During winter, lack of water, cold temperatures and reduced sunlight reduce the rate of photosynthesis in evergreen trees such as pine trees.
Pine trees are evergreen trees in that they they are green all year as they do not lose their leaves like other trees. This is because is because they have reduced needle-like leaves which they keep all-year round.
Thus, evergreens are able to photosynthesize even in winter when other trees lose their leaves. However, the rate of photosynthesis is greatly reduced because of winter conditions.
These conditions of factors that reduce the rate of photosynthesis include:
Lack of water: during winter, water is scarce because most water freezes to form ice. As water is needed for photosynthesis, the rate of photosynthesis is reduced.Cold temperature: in very cold conditions, water in between the cells of winter evergreen trees can form ice leading to dehydration. They plants compensate for this by closing their stomata to avoid water loss through transpiration. Closing of the stomata prevents the diffusion into the cell of carbon dioxide, thus limiting photosynthesis.Reduced sunlight: sunlight which is needed for photosynthesis is reduced during winter, thus, reducing the rate of photosynthesis.Thus, during winter, lack of water, cold temperatures and reduced sunlight reduce the rate of photosynthesis in evergreen trees such as pine trees.

The terms "run" and "tumble" are generally associated with _____?
Answers
The term "run and tumble" method in bacteria is associated with movement.
Why do bacteria tumble?The tendency to tumble is increased when the bacterium perceives conditions to be very bad when the concentrations of attractant decrease or concentrations of repellent increase. Tumbling is suppressed and cells keep working when they detect that conditions inside the cells are improving.
Wild-type bacteria swimming in sparse suspensions has a movement pattern known as "run and tumble," which is characterized by straight trajectories which are 'run' distribute by shorter, reorientation which is tumbles. This can be achieved by rotating their flagella in the counterclockwise, or clockwise direction respectively.
So we can conclude that movement is the term associated with the "run and tumble" method.

Floral design: what would happen if a wholesaler stored a shipping crate of gladioli horizontally? What would you suggest that the wholesaler do?
Answers
The gladioli would worsen it's quality if held horizontally, therefore, the wholesaler should keep them upright while storage and transportation.
Gladioli, like the majority of spike-type flowers, are extremely sensitive to the pull of gravity and constantly have a tendency to grow upward, especially in warm climates. This may cause the upper portion of the spike to permanently distort, lowering the quality of the flowers as a result. Gladioli should be kept upright during the postharvest operations to prevent this result. Only when the flowers are kept at a low temperature during storage and transit may this restriction be loosened.
Gladiolus quality criteria include stem strength and straightness, absence of damage and disease, and maturity. Hang the corms in a cool, dry, well-ventilated area by placing them in mesh bags or old nylon stockings. 35 to 45 degrees Fahrenheit should be the storage temperature range.

during the process of cell division what would be the result, if only nuclear division occured, without cytokinesis?
Answers
If only nuclear division occurs without cytokinesis during the process of cell division, the result would be the formation of multinucleated cells or cells with multiple nuclei.
Cell division consists of two main processes: nuclear division (mitosis) and cytoplasmic division (cytokinesis). During nuclear division, the nucleus of the cell divides, ensuring that each daughter cell receives a complete set of chromosomes.
On the other hand, cytokinesis involves the division of the cytoplasm, resulting in the separation of the two daughter cells.
If only nuclear division occurs without cytokinesis, the cell would undergo mitosis but not divide into two distinct cells. As a result, the daughter cells would share a common cytoplasm, leading to the formation of multinucleated cells or cells with multiple nuclei. These multinucleated cells are known as syncytia.
Syncytia can be found in various biological processes and tissues. For example, muscle fibers are multinucleated cells formed by the fusion of multiple precursor cells during development. Similarly, certain fungal hyphae and giant algae cells can have multiple nuclei due to incomplete cytokinesis.
In summary, if only nuclear division occurs without cytokinesis, the cell would produce multinucleated cells or cells with multiple nuclei, where the daughter cells remain connected by a shared cytoplasm.

Answers
The offspring will have a 1:1 ratio of XBXb carrier females and XBY normal males, as only the female offspring can inherit the Xb allele and develop color blindness.
What is Offspring?
Offspring refers to the biological descendants or progeny of an organism, produced by sexual or asexual reproduction. It can also refer to the young of an animal, especially a mammal, in its early stages of development. Offspring inherit traits and genetic information from their parents through the process of inheritance.
Codominance: In codominance, both alleles are expressed equally in the heterozygous condition. An example is the ABO blood group system in humans, where there are three alleles for the gene that determines blood type: IA, IB, and i.
Punnett square for a cross between an individual with IAIA genotype and an individual with IBIB genotype
IA IA
-----------------
IB | IBIA | IBIA |
IB | IBIA | IBIA |
-----------------
All offspring will have the genotype IAIB, which expresses both alleles equally and results in the AB blood type.
Incomplete dominance: In incomplete dominance, the heterozygous phenotype is intermediate between the two homozygous phenotypes. An example is flower color in snapdragons, where the alleles for red and white flowers show incomplete dominance.
Punnett square for a cross between two individuals with RW genotype:
R W
-------------
R | RR | RW |
W | RW | WW |
-------------
In this case, the offspring will have a 1:2:1 ratio of RR (red), RW (pink), and WW (white) phenotypes.
Multiple alleles: In multiple alleles, there are more than two alleles for a particular gene. An example is the gene for human blood type, which has three alleles: IA, IB, and i.
Punnett square for a cross between an individual with IAIB genotype and an individual with ii genotype:
i i
-------------
IA | IAi | IAi |
IB | IBi | IBi |
i | ii | ii |
-------------
The offspring will have a 1:1:1:1 ratio of IAi, IBi, ii, and IAIB genotypes, resulting in a mix of A, B, AB, and O blood types.
Sex-linked traits: Sex-linked traits are determined by genes located on the X or Y chromosomes. An example is color blindness, which is caused by a recessive allele on the X chromosome.
Punnett square for a cross between a carrier female (XBXb) and a normal male (XY):
Xb Y
-------------
XB | XBXb | XBY |

How many grams of CaCO3 are needed to prepare 3.3 L of a 8 M CaCO3 solution (FW of CaCO3 = 100.09 g/mol).Do not include units in your answer. Report your answer to the nearest two decimal places.
Answers
Answer: 2642.38 g
Explanation:
This is the equation for molarity. You are being asking to find grams and we will use this equation to do just that.
Molarity = moles/liters or M = mol/L
Step 1: Identify all known given quantities.
M = mol/L
M = 8 M
mol = unknown quantity
L = 3.3
Step 2: Place known values into the equation M = mol/L.
8 = mol/3.3
Step 3: Isolate the unknown variable, in this case mol.
8 x 3.3 = (mol/3.3) x 3.3
26.4 = mol
Note: When you multiple by 3.3 on each side of the equation, you may cancel both 3.3 on the right side of the equation.
You now have the number of moles. This can be used to find the grams.
Step 4: Use moles in step 3 to find grams of CaCO3. Molar mass was provided as 100.09 g/mol for CaCO3.
26.4 mol x (100.09 g/mol) = 2642.376 g
The mol units cancel and you are left with grams.
The final answer to two decimal places = 2642.38 g
