Answer:
Acid rain is an umbrella term, which is used
to cover a number of different pollution
processes. The pH of acid rain is ten, fold
difference between numbers. India illustrates
the drastic effect of acid rain on agricultural
productivity researchers there found that
wheat growing near a coal fired power plant
where SO2 deposition was almost five times
greater than the critical load (the amount of
the soil can safely absorb without harm)
suffered a 49% reduction in yield. In the
present investigation to assess the effect of
acid rain on the plant growth, the plant of
Triticum aestivum and Raphanus sativus
were grown in different wooden boxes and
three different plastic boxes. The different pH
(2.0, 4.0, 5.0) of simulated rain does were
sprayed on the plant and after last dose the
specific visual difference was seen in seed
germination. increased acidic level (pH 2.0) of the rain water affects the seed germination by the rate of 40% as compared to that of lower level of acidity (pH 4.0 and 5.0)

What might prevent two groups of organisms from reproducing together ?
Answer:
A negative power source or a negative bond
Explanation:
when 2 organisms can't reproduce together is bc it's nonliving or has a negative bond
Prezygotic and postzygotic barriers keep species apart from one another and prevent two groups of organisms from reproducing together.
How are organisms reproducing?Acting before and after the development of a zygote, respectively, these barriers prevent creatures of different species from mating to create fruitful offspring. These obstacles continue to keep species' reproductive isolation.
Pre-zygotic and post-zygotic barriers are the two main categories of restrictions on reproduction. Post-zygotic barriers impede hybridization after fertilization, and pre-zygotic barriers do the same.
Therefore, these barriers, which take effect both before and after the development of a zygote, prevent creatures of different species from mating to generate fruitful offspring.

Researchers studying a small milkweed plant population note that some plants produce a toxin and other plants do not. They identify the gene responsible for toxin production. The dominant allele (T) codes for an enzyme that makes the toxin, and the recessive allele (t) codes for a nonfunctional enzyme that cannot produce the toxin. Heterozygotes produce an intermediate amount of toxin. In this population, the genotypic frequencies are TT= 56, Tt = 28, and tt = 16. For each problem below, show all of your work. A. Calculate the observed allele frequencies. B. Calculate the expected genotypic frequencies. C. Is this population in HW equilibrium? If not, explain what may cause it to not be (for example, is one level of toxin more adaptive than others?).

Identify two examples of environmental factors that may impact salivary peroxidase activity. Describe how each of the environmental factors would affect the reaction rate of the enzyme.
Predict the effects of a long-time cigarette smoker and the impacts on activity levels of salivary peroxidase. Provide reasoning to justify your prediction.
Answer:
Examples of environmental factors that may alter salivary peroxidase include periodontitis, oral hygiene, presence of heavy metal ions, bacteria (e.g., Streptococcus gordonii), anaerobic conditions, temperature, pH, etc.
Explanation:
Peroxidase is an enzyme found in all aerobic cells that act to convert toxic hydrogen peroxide (H2O2) into dioxygen (O2) and water (H2O). This enzyme plays an important non-specific defensive role against proliferating micro-organisms that cause periodontal diseases such as periodontitis, which is a serious inflammatory disease affecting the tissues around the teeth. The most common environmental factors influencing the development of periodontitis include oral hygiene, smoking and age. In this regard, it has recently been shown that there is a positive correlation between salivary peroxidase activity and periodontal health, especially in non-smoker individuals. In consequence, it is expected that smoker individuals are more prone to suffer periodontal diseases by reduction of the salivary peroxidase levels.

What happens during the calvin cycle? how does the calvin cycle depend on the light reactions?
Answer:
-The ATP provides the energy, and the NADPH supplies the electrons for the Calvin cycle, which converts carbon dioxide to sugar. The ADP and NADP+ that result from the Calvin cycle shuttle back to the light reactions, which regenerate ATP and NADPH.

Write down the clinical findings which are least suggestive of left-sided heart failure?
Answer:
Adverse heart conditions do not occur in isolation. It is usually accompanied by other risk factors, like coronary artery dysfunction, diabetes, high blood pressure, etc.
In addition to the above, the following factors are indicative of left-sided heart failure:
Shortness of breath caused by the collection of fluid in the lungs. Shortness of breath usually becomes pronounced upon physical exertionAn increase in the girth of the torso (mainly the abdomen) due to ascites which is the buildup of fluid in the abdomen.engorged scrotum (in males of course)Explanation:
Left-Sided Heart Failure is simply the inability of the heart to pump oxygen-rich blood into the body.
Blood filled with oxygen is moved from the lungs to the atrium on the left and then to the left ventricle. The blood is then pumped from the ventricle on the left to other parts of the body by a contracting and relaxing action. Left-sided heart failure can be classified into two:
Systolic Failure and Diastolic Failure1. Systolic Dysfunction: When the left ventricle can no longer shrink properly, the pressure with which the heart can pump enough blood into circulation is reduced.
2. Diastolic Dysfunction: This occurs when the left ventricle can no longer relax as it ought to due to the hardening of the muscle.

• 11. Thinking about trophic levels, the type of energy we use from a natural resource comes through a transfer of what, which can also be classified as radiation?
Answer:
Solar energy
Explanation:
There are different kinds of energy, and one of them is radiation. By concept, radiation refers to the emission, propagation, and transference of energy in the form of electromagnetic waves or particles. Living beings depend on solar energy from their origins.
Throughout the trophic web, there exists a process of energy transference through the different trophic levels, in which every organism feeds on the preceding one and becomes food for the next one. Producers take solar energy and transform it into chemical energy, which is the one from one level to the other.
Energy flow: From the whole quantity of solar energy that reaches the earth's surface, only 0.1 or 1% is absorbed by autotroph organisms or producers.
From this input of solar energy, it begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is finally dissipated in the environment.
At each trophic level, it occurs an energy transfer from one level to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule". This is, as a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time.
The progressive reduction of energy determines the number of trophic levels (4 or 5).
Can two plants with white flowers produce offspring with purple flowers?
Answer:
Yes, if both parents are heterozygous for the trait.
Explanation:
For example, they may recognize that a plant with white flowers crossed with itself or another plant with white flowers will produce only white flowered plants, while a purple-flowered plant crossed with itself or another purple-flowered plant sometimes produces white-flowered offspring.
