The Fishing industries in the United States are controlled by the:

The catch limit for the species is set by the federal government. The federal government supports the fisheries by improving coastal employment, food production, fisher's welfare, and sustainability of the fishing sector.

A major impact of combustion on water quality is the potential for increased precipitation. Runoff can carry suspended soil particles, dissolved inorganic nutrients, and other materials into nearby rivers and lakes, degrading water quality and damaging fish habitat.

Park Williams, an associate professor of geography at UCLA and lead author of the study, said wildfires burn vegetation that would otherwise draw water from the ground and block precipitation before it reaches the ground. said to improve the flow.

Wildfires increase the vulnerability of watersheds to flooding and erosion, causing short-term and long-term damage to water supplies. may have an impact. The increased cost of treatment, the need for alternative medicine, and reduced storage capacity. Fire as a destructive force can rapidly consume large amounts of biomass and cause adverse effects such as soil erosion, post-fire water runoff, and air pollution.

Complete question:

1. You found a new species of garden pea and have decided to repeat Mendel’s experiments. You have obtained two true-breeding pea plants that are tall (T) with yellow pods (g), and short (t) with green pods (G), respectively. Capital letters indicate dominant traits.

a. What is the genotype and phenotype of the F1 generation? (2p)

b. You allowed self-fertilization in F1 generation and obtained F2 generation. Using Punnett square to obtain the phenotypes, genotypes and their respective ratios. (4p)  

2. If you obtained 1248 offspring in the F2 generation in Question 1, calculate how many offspring of each phenotypic class you would expect to have. (4p)

3. When you finish questions 1 and 2, under what assumption/hypothesis did you perform your analysis/calculation? Is there an alternative assumption/hypothesis, which may result in a different conclusion? If yes, what is the alternative assumption/hypothesis and what kind of offspring and in what numbers do you expect to obtain? (4p)    

4. You only need to answer A or B to get this 6p. Please indicate which question you are answering. In your experiment, you found the following offspring only: Tall green: 626 offspring. Tall yellow: 313 offspring. Short green: 309 offspring.  

A: If you stay with your original hypothesis/assumption, test it using chi2 test and analyze the result (whether you want to reject the hypothesis and why).

B: If you believe that the alternative hypothesis fits better with your data, test it using chi2 test and analyze the result (whether you want to accept the hypothesis and why).

Answer:

1) a. 100% of the progeny will be dihybrid, TtGg, exhibiting the phenotype    

       Tall plants with green pods.

   b.  F2 Gentotype:

16 ----------------- 1248 individuals  --------------- 100% of the progeny

9 T-G- ----------- X = 702 individuals-------------X = 56.25%

3 T-gg ----------- X = 234 individuals ----------- X = 18.75%

3 ttG- ------------- X = 234 individuals ---------- X = 18.75%

1 ttgg ------------- X = 78 individuals ------------ X = 6.25%

Expected               702                  234                       234                       78

(Obs-Exp)²/Exp     8.23                  26.7                        24                        78

X² = Σ(Obs-Exp)²/Exp = 8.23 + 23.7 + 24 + 78 = 136.93 ≅ 137

Freedom degrees = genotypes - number of alleles = 9 - 4 = 5

Significance level, 5% = 0.05

Table value/ Critical value = 11.07

X² = 137

X² > Critica value

137 > 11.07

There is enough evidence to reject the null hypothesis, meaning that the difference between the observed number of individuals and the expected ones is statistically significant. The population is not under equilibrium H-W. Alleles do not assort independently.    

Answer: The botanist should use sexual reproduction to make the new plants because asexual reproduction will only produce spider plant offspring with the same types of traits as the parents.

Explanation:

Assuming that the botanist already has spider plants with larger flowers in their nursery, in order to develop a large number of the plant based on the same traits, asexual reproduction method should be used.

Asexual reproduction method is preferred because:

Sexual reproduction leads to variation such that daughter plants will not have exactly the same traits as their parents. The number of plants that can be produced sexually is also limited.

Explanation:

Answer:

Hydrogen atom & glucose molecule --- atomic.

Herpesvirus, DNA --- ultramicroscopic.

Protozoan, Rickettsia - microscopic.

Roundworm and algae --- macroscopic

Explanation:

1) Hydrogen atom & glucose molecule --- atomic.

The atomic size level, which interacts with atoms as well as small molecules, is much lower than the ultramicroscopic range.

2) Herpesvirus, DNA --- ultramicroscopic.

Ultramicroscopic particles are very tiny structures that cannot be seen using a conventional optical microscope, necessitating the use of an electron microscope. Viruses and DNA falls into this group since they are much smaller than tiny species like bacteria.

3) Protozoan, Rickettsia - microscopic.

Microscopic species are much smaller than macroscopic organisms because they cannot be observed by the naked human eye and must be viewed through a microscope. The size range for microscopic particles is [tex]( 10^3 \ \ to \ \ 10^{10})[/tex], which contains protozoans and Rickettsia (a gram-negative, non-motile bacteria genus).

4) Roundworm and algae --- macroscopic

Naked eyes can see macroscopic organisms; for example, several types of circular worms and algae can be seen by them.

Explanation:

Spores of two types to spores of one type is not the trend to plant evolution because first the spores of one type is present in living organisms but with the passage of time evolution occurs that will leads to formation of  spores of two types happen in living organisms. There are types of spores present in plants such as microspores, which produces male gametophytes, and megaspores, which produce female gametophytes while on the other hand, spores of one type is present in plants having asexual reproduction.

Explanation:

Sometimes it can be tricky to know whether or not a chemical reaction has occurred. For example, when you melt ice into water, you can write the process in terms of a chemical reaction. However, the chemical formula on both sides of the reaction is the same. Since the chemical identity of the matter in question is unchanged, this process represents a physical change.

Thus melting point is a physical property. On the other hand, flammability is a chemical property of matter because the only way to know how readily a substance ignites is to burn it. In the chemical reaction for combustion, the reactants and products are different.

Answer: 13 is a trisomy

Explanation:

Answer:

Explanation:

Proteins, such as RNA (ribonucleic acid) polymerase, were loaded into lane 2. TFIIB and TFIID are two forms of TFII. These proteins attach to the fragment of DNA. Furthermore, these proteins shield DNA from the DNase enzyme, which may trigger DNA to split. As a result of the above findings, we may conclude that the inserting proteins(RNA polymerase, TFIID and TR 8 proteins) cover the area between 500 and 800 bp (base pair) in the DNase I footprinting experiment.

As a consequence, the length duration is 300bp since the promoter area is about 500-800bp and is not digested by DNase after incubation of inserting proteins.
