Upon completion of seeding a flower and a vegetable, research and identify the optimum propagation conditions, such as, water and light demand, appropriate temperature, and, other elements that may affect the germination from seeding. Compare your research findings with your existing conditions. If any discrepancies found, address how you would like to mitigate. Describe the entire process in your weekly lab report journal. Add photos, sketches or other supplementary information, if necessary.
Answer:
Needs optimum environmental conditions.
Explanation:
Seedling, a flower and a vegetable needs suitable conditions for growth and development. All of the three stages of plant life cycle requires optimum water, fertilizers and light intensity in order to grow and develop at full speed. Seeds need a specific temperature in order to germinate. Most seeds germinate when the soil temperature is between 68 and 86 Fahrenheit. In the same way the plant also needs specific temperature for bearing flowers. All the stages requires optimum water in the soil for absorption.

Using the organisms you identified in part B, create a food web for the ecosystem you chose. Use this sample food web for reference, although your food web will contain fewer organisms. Note that your food web does not have to include images, but you may include them if you choose. However, be sure to include arrows to indicate the direction of energy flow in your food web. Design your food web using any method listed below:
Unfortunately you did not introduce the organisms identified in part B, as the question shows. This makes it impossible for me to answer this question, but I will try and help as best I can.
In the figure attached to the question below, it is possible to see an example of a food web and the arrows that indicate the direction of the energy flow within this food web.
In this sense, we can determine that a food web is the set of food chains that complete and mix. A food chain shows how living organisms organize themselves so that one feeds on the other, whereas in the food web, this food chain is shown in a more realistic way, as it shows how food chains mix and interact within the ecosystem, as they do not there are food chains isolated in nature.

what can happen during the cycle of photosynthesis with increasing concentrations of Atrazine?
Answer:
By inhibiting photosynthesis, Atrazine kills plants. Photosynthesis, which is unique to living green plants, occurs when light energy becomes the chemical energy required for food production.
Simply stated, plants eventually die of hunger when food production stops. Atrazine selectively kills unwanted plants (weeds) competing with suitable plants for water and nutrients (crops, turfgrass). It is thus a beneficial tool for both farming and urban plants.
Explanation:
In Texas maize and grain sorghum production, Atrazine is the most often used herbicide. In several "weed and feed" preparations for domestic plowing and commercial turf-grass weed control, it is also often found as an active ingredient.
With its broad use, atrazine has been identified in minute concentrations in Texas ground and surface waterways. Because of this, it is crucial to understand atrazine behavior in the environment and the potential for harmful impacts on human and animal health and on other non-target organisms.
One of the most important outcomes of extreme stress or tension is the effect on the ___________ system, which usually protects use from invading toxins and micro-organisms that can negatively impact our health.
Answer:
Immune
Explanation:
The immune system helps to protect our body from all sort of organisms ranging from invading toxins and micro-organisms which negatively affects an individual’s health and well being.
Stress has an adverse effect on the immune system such that it weakens and suppresses the functions of the required antibodies in the body system. This is the reason why many aged people fall sick because they have gone through more stress when compared to younger people.

Congestive heart failure (CHF) is an inability of the heart to pump sufficient blood to the body. One sign of CHF is excess fluid in the tissue spaces, known as edema. Describe the location of the edema if the left side of the heart fails, compared to the location of edema if the right side of the heart fails.
Answer:
Explanation:
When the left side of the heart (left ventricle) starts to fail, fluid collects in the lungs (edema). This extra fluid in the lungs (pulmonary congestion) makes it more difficult for the airways to expand as a person inhales. Breathing becomes more difficult and the person may feel short of breath, particularly with activity or when lying down.
When the right side of the heart (right ventricle) starts to fail, fluid begins to collect in the feet and lower legs. Puffy leg swelling (edema) is a sign of right heart failure, especially if the edema is pitting edema. With pitting edema, a finger pressed on the swollen leg leaves an imprint. Non-pitting edema is not caused by heart failure.

If a less concentrated initial solution of sodium bicarbonate was used in beaker C, would that solution require more or less bicarbonate to neutralize the acid? Why?
Less bicarbonate would be required to neutralize the acid if a less concentrated initial solution of sodium bicarbonate was used in beaker C.
What is bicarbonate?Bicarbonate is a naturally occurring chemical compound composed of sodium, hydrogen and carbonate ions. It is a salt and a weak acid, and its chemical formula is NaHCO3. Bicarbonate has many uses, including baking, cleaning, medicine, and neutralizing acids. Baking soda, which is sodium bicarbonate, is used in baking as a leavening agent. It acts to create air bubbles in dough, which helps breads and cakes to rise. Bicarbonate is also used in cleaning products as a mild abrasive and a pH buffer.
This is because a less concentrated solution will have fewer moles of bicarbonate per liter of solution, thus requiring less bicarbonate to neutralize the same amount of acid.

define cell and atom.....
Cell: A cell is the structural and fundamental unit of life. The study of cells from its basic structure to the functions of every cell organelle is called Cell Biology.
Atom: atom is the smallest component of an element, characterized by a sharing of the chemical properties of the element and a nucleus with neutrons, protons and electrons. The protons and the neutrons reside in the nucleus.
whats the difference between atom and cell?
function wise atoms take part in every chemical reaction while cells are responsible for the development and growth of living existences. Atoms do not have life. They do not need food, water, and they do not reproduce. Cells are alive. Cells consume food and water and can reproduce. Atoms construct molecules and Cells make tissues for organs.
Hemophilia is an X-linked recessive condition in which blood does not clot properly. Queen Victoria of England had one allele for hemophilia. Most of her male descendants had the disorder, but few females had it. Why did hemophilia occur more frequently in Queen Victoria’s male descendants?
Answer:
Because hemophilia is an X-linked recessive condition.
Explanation:
As the problem states, hemophilia is an X-linked recessive condition.
Meaning that in Queen Victoria's female descendants (coded XX) which inherited the Queen's one allele, for hemophilia to appear in them it would be necessary to inherit another hemophillia-carrying allele from the father.The Queen's male descendants (coded XY) would always manifest hemophilia if they inherited the Queen's hemophilia allele, as they possesed only one X gene.what happens to the respiratory system of a pilot who is in a power dive in supersonic plane.

Predict what will happen to the concentration of pyruvate, NADH and H+ when the Krebs cycle is stopped by arsenic
Answer: Pyruvate would increase, NADH would decrease, and intermembrane H+ would decrease as well.
Explanation:
Glycolysis would raise pyruvate, but the Krebs Cycle would not produce NADH, decreasing it. No protons (H+) will be pushed into the intermembrane gap, lowering its H+ content and raising its pH.
What is Kreb's cycle?The tricarboxylic acid (TCA) cycle, commonly referred to as the Krebs cycle or the citric acid cycle, is the primary route that cells use in order to acquire energy and is an essential component of aerobic respiration. The cycle transforms the oxidative potential of acetyl coenzyme A (acetyl CoA) into the reductive potential of nicotinamide adenine dinucleotide (NADH).
The synthesis of ATP via the Krebs cycle is disrupted when arsenic is present because it prevents pyruvate from being converted into acetyl coenzyme A (acetyl-CoA). In addition to the effects described above, arsenic also prevents glucose uptake at the cellular level, as well as gluconeogenesis, the oxidation of fatty acids, and additional acetyl-CoA formation.

The scientists mapping the SNPs in the human genome noticed that groups of SNPs tended to be inherited together, in blocks known as haplotypes, ranging in length from 5,000 to 200,000 base pairs. There are as few as four or five commonly occurring combinations of SNPs per haplotype. Integrating what you've learned throughout this chapter and this unit, propose an explanation for this observation.
Answer:
SNPs have shown that only 0.1 % of DNA sequences are different in the human genome between different individuals, thereby all the inherited phenotypic variation observed in our species is associated with only 0.1 % of differences at the genome level
Explanation:
Haplotypes are block-like sequences of DNA that are inherited together due to low recombination rates. Moreover, single-nucleotide polymorphism (SNP) mapping is a very useful methodology used to map the site of SNP mutations (i.e., SNP variants). In this regard, it has been observed that there are approximately 10 million common SNPs in the human genome. These SNPs contribute to the wide range of phenotypic variation observed in human populations for different traits (e.g., eye color, hair, weight, height, etc). Moreover, researchers have determined that SNPs can be clustered into haplotypes, thereby haplotypes can be accurately sampled by as few as approx. 300,000 selected SNPs, which are sufficient to represent all of the genetic variation across different human genomes.
