Which layer is the lowest of the atmosphere?
Answer:
The Troposphere.
Explanation:
Suppose that a late succession plant that is surrounded by early succession plants grows at a rate of 0.5 cm per day. If the early succession plants are removed experimentally, the late succession plants are observed to grow at a rate of 0.9 cm per day. This experiment shows that the early succession plants have a _______ effect on the late succession plants, and this observation is most consistent with the _______ model of succession.
Answer:
negative, inhibition
Explanation:
The experiment in the illustration shows that early succession plants have a negative effect on the late succession plants, and the observation is most consistent with the inhibition model of succession.
That the late succession plant thrives better in the absence of the early succession plants means that the early succession plant has been impacting the growth of the late succession plant negatively. This is consistent with the inhibition model of succession.
There are 3 different models of succession. These include;
Facilitation model in which colonists modify the environment to favor the growth of later successional species.Tolerance model in which early colonists' modification of the environment has no positive or negative impact on the growth of later successional species.Inhibition model in which early colonists modify the environment to inhibit the growth of later successional species.A peptide has the sequence of Gly-Ser-Glu-Leu-Ala-His-Gly-Arg-Leu-Ala-PheCys-Leu. (pKR=4.25, 6.0, 8.2, 12.5. Assume pKa’s of amino terminus and carboxyl terminus are 9.6 and 2.3, respectively.) The PI of the peptide is close to:_______
a. 7.1
b. 7.8
c. 5.1
d. 8.2
e. 10.3
Answer:
The correct answer is option a. "7.1".
Explanation:
One easy way to determine if a peptide sequence is acidic, basic or neutral is to check for the number of amino acid residues that are acidic, basic or neutral. In this case, most amino acid residues are neutral, which mean that under neutral conditions they have a pKa close to 7.0. Particularly, the content of 3 leucine, 2 alanine and 2 glycine residues determines that the peptide have a pI of around 7.1.

what solution describes a saturated solution?
Answer:
This is not my answer, I found it on the internet.
No more solutes can be dissolved in a saturated solution at a given temperature and pressure.
Explanation:
A saturated solution is a solution that consists of maximum amount and concentration of the solute that is dissolved in the solvent.
The extra amount of solute cannot be dissolved in a saturated solution.
The saturated solution is composed of solute and solvent and solvent cannot dissolve more solute at some extent.
The carbonated beverage is an ideal example of saturated solution.
A saturated solution is one that contains the greatest concentration and amount of the solute dissolved in the solvent. In a saturated solution, the excess solute cannot dissolve.
What is Saturated solution?Solvent and solute make up the saturated solution, and to a certain extent, solvent cannot dissolve more solute. A saturated solution is best exemplified by fizzy beverages.
A solute's solubility is the greatest amount of that solute that can dissolve in a solvent at a given temperature and pressure. The moles of solute per volume (mol/L) or the mass of solute per mass of solvent (g/g) are other common ways to express solubility.
There is typically a limit to how much solute can dissolve in a given amount of solvent, even for extremely soluble compounds. In general, temperature and pressure—for gases—as well as the energy components we have already covered affect a substance's solubility.
Therefore, A saturated solution is one that contains the greatest concentration and amount of the solute dissolved in the solvent. In a saturated solution, the excess solute cannot dissolve.

Place the steps involved in burning coal to create electricity in the correct order.
Water boils, creating steam.
Coal is burned
Turbines generate electrical energy.
Moving steam turns turbines.
Answer and Explanation:
Coal is burned: Electrical Centrals burn coal with which they get enough heat. The coal might be pulverized to increase the effective combustion area. Water boils, creating steam. The heat generated by the burning coal is used to create water vapor that rises and moves turbines. This occurs when water passing through some tubes is heated by the hot gases coming from the burning coal, turning it into high-pressure steam. Moving steam turns turbines. The high-pressure steam is taken to turbines where it expands and moves the rotor which is the moving part of the turbines. Turbines generate electrical energy. The turbines are connected to a generator that transforms the energy produced by the rotor into electricity.Answer:
Coal is burned

In this question given, the data is portraying the Temperature versus Photosynthetic rate. This means that the experimenter is testing to see the effect of varying temperatures on the photosynthetic rate. Hence, the TEMPERATURE is the independent variable because it is the variable being changed.
What sequence elements could be looked for within the inserted sequence that would help place it in one of the three families?
Answer:
DNA transposons, viral-like transposable elements, and non-LTR retrotransposons
Explanation:
Transposable Elements (TEs) are genetic mobile elements that can change its position within a genome, thereby producing mutations at the genomic sites where they are inserted. According to their composition and structure, TEs can be divided into three main types: DNA transposons, viral-like transposable elements, and non-long terminal repeat (non-LTR) retrotransposons (also known as polyA retrotransposons). In the first place, DNA transposons are composed of conserved inverted repeat sequences at both ends of the element which are surrounded by target site duplications (TSDs). Moreover, viral-like TEs contain LTRs and they encode reverse transcriptase enzymes. Finally, non-LTR retrotransposons contain a poly(A) tail at the 3′ end, but they don't have inverted repeats.
To protect our rights, the Constitution divides powers between the federal government's branches. This principle is called "separation of powers." Each branch of government holds distinct but equal authority. For example, Congress has the power to create laws, while the president has the power to execute these laws. The preamble states the purpose of "securing the Blessings of Liberty." Our freedoms are secured when power is not concentrated in any single branch of government. This helps our government to provide for our needs while respecting our rights.
Answer:
Explanation below
Explanation:
Separation of powers is very important and crucial in federal type of government. This is helpful because it decentralized the power, and prevent one arm of government from being a dominating force.

Think critically A restaurant owner wants to serve fresh-cut fruit. What factors might be considered in choosing a recipe and preparation method
Answer:
Explanation:
1.Oxidation- some fruit after cutting on exposure to air begin to oxidate this leads to a change of color, this color change could range from light brown to dark brown in some fruits such as apple this could make it unappealing to to the consumer.
2. Shelf life- How long can the fruits start after exposure to air before it begins to loose its taste assuming they are not consumed immediately. This have to considered in selecting fruits
3. Time- How long will it take to prepare and make the fruits ready, some fruits requires some thorough cleaning, professional cutting skill
if all will be available and will meet up the time required for the fruits to be served.

Color blindness is a recessive X-linked trait. A normal couple has a color-blind child. At least one member of the couple's families is colorblind, who is this most likely to be?a) the child's paternal grandmotherb) the child's paternal grandmother or grandfatherc) the child's maternal grandmotherd) the child's paternal grandfathere) the child's maternal grandfather
Answer:
c or e
Explanation:
The correct answer would be the child's maternal grandmother or grandfather.
For X-linked traits, only females can be carriers while males are either affected or totally free from the trait. This is because females have two X (XX) chromosomes while males have only one (XY).
Since the couple is normal, it means the father is free from color blindness. The only available option now is the mother and since she is phenotypically normal, it means that she is a carrier of the disease. She must have inherited the allele from either of her parents, but not from both. If she had inherited an affected X chromosome from each of her parents, she would have been phenotypically affected for color blindness.
Hence, the child's color-blind allele can only be traced back to either of the child's maternal grandmother or grandfather.
The correct option is c or e.
The member of the couple's family who is this most likely to be colorblind is the child's maternal grandfather.
An X-linked recessive inherited genetic trait is transmitted from parent to child through mutations in genes localized on the X chromosome.In males, X-linked recessive traits are always expressed because males contain only one X chromosome.In consequence, in this case, the mother should be a normal carrier of the disease/condition, thereby her dominant X-linked allele can mask the expression of the recessive (daltonic) allele, which is passed to the child from the maternal grandfather.In conclusion, the member of the couple's family who is this most likely to be colorblind is the child's maternal grandfather.

Victor has been studying the vascular systems of plants. He wanted to find out if food coloring would travel up the stalk of celery faster if the temperature of the water increased. Victor set up his experiment with three cups of colored water at different temperatures, three equal sized celery stalks, and a stopwatch. Cup A was filled with colored water at 21 C. Cup B was filled with cold colored water at 4 C, and Cup C was filled with warm colored water at 30 C. One celery stalk was placed in each cup at the same time. Victor timed how long it took the colored water to travel to the leaves at the top of the celery stalk. He measured the time in minutes. What is the independent variable
Answer:
temperature
Explanation:
The independent variable would be the colored water at different temperatures.
The independent variables are changeable or controllable variables supplied directly by researchers in the course of experiments. They produce effects on the dependent variable and are thus referred to as the 'cause' variable. The dependent variables are referred to as the 'effect' variables because their values vary based on that of the independent variables.
In this case, the only controlled variable of all the variables supplied by Victor is the temperature of the colored water. Changing the temperature of the colored water is expected to have effects on the time it will take for the colored water to travel to up the stalk of celery. Hence, the temperature is considered as the independent variable while the time it takes for the colored water to travel to the leave would be the dependent variable.
