O B. H2O + energy
O c. C&H 206 + O2
O D. CO2 + H20
Answers
The products in the chemical reaction for photosynthesis are [tex]C_{6} H_{12}O_{6}[/tex](glucose) and [tex]O_2[/tex] (oxygen). The correct answer is C.
During photosynthesis, plants use carbon dioxide ([tex]CO_2[/tex]), water ([tex]H_2O[/tex]), and energy from sunlight to produce glucose ([tex]C_{6}H_{12}O_{6[/tex]) and oxygen ([tex]O_2[/tex]).
The equation represents the process of photosynthesis, where carbon dioxide and water are combined in the presence of sunlight to create glucose and release oxygen as a byproduct.
The glucose produced serves as the main energy source for plants, which can be used for growth, maintenance, and other metabolic processes.
Oxygen is released into the atmosphere as a waste product of photosynthesis and is essential for the survival of many organisms, including humans, as it is required for cellular respiration.
Therefore, the correct products of the chemical reaction in the equation are [tex]C_{6} H_{12}O_{6}[/tex] (glucose) and [tex]O_2[/tex] (oxygen). The correct answer is C.

what is the average time for the toy to move 1.0m. on dirt? A) 20.2 s, B) 24.2 s, C) 28.1 s, D) 60.7 s. " Need help asap please and thank you. Only correct answers. I tried and got it wrong. The correct answer is 20.2 s
Answers
The correct answer is A. 20.2 s
Explanation:
The table shows there were three trials to measure how much time a toy car needs to move 1 meter on different surfaces. Now, to find the average time on a surface simply add the results of the three trials and divide this by number 3 (number of trials). The process to know the average time on dirt is shown below:
20 + 19.2 + 21.5 = 60.7 - Results of each of the trials
60.7 ÷ 3 = 20.2 s - Divide the total by the number of trials
This means the average time for the toy to move on dirt was 20.2s

How would you describe a bottle that contains 0.95 moles of hydrogen peroxide per liter of solution?
Answers
Answer:
A bottle that contains 0.95 moles of hydrogen peroxide per liter of solution contains 32.31 g of hydrogen peroxide per liter of the solution.
Explanation:
First, recall that:
Molarity of a substance = no of moles of the substance/volume of the solution in liters.
In this case, the number of moles of hydrogen peroxide is 0.95 mole while the volume of the solution is one liter. Thus;
Molarity of hydrogen peroxide = 0.95/1 = 0.95 M.
Also recall that:
no of moles of a substance = mass of the substance/molar mass of the substance.
Thus;
mass of substance = no of moles x molar mass.
In this case, the no of moles of hydrogen peroxide is 0.95 while the molar mass is 34.01 g/mol. Hence;
mass of hydrogen peroxide = 0.95 x 34.01 = 32.31 g
Hence, a bottle that contains 0.95 moles of hydrogen peroxide per liter of solution contains 32.31 g of hydrogen peroxide per liter of the solution. The solution also has a hydrogen peroxide molarity of 0.95 M.
The amount of hydrogen peroxide in the solution can be expressed in grams per Litre as 32.31 gram of hydrogen peroxide per Litre of the solution.
The amount of mole of hydrogen peroxide in the solution = 0.95 moles
The Molar mass of hydrogen peroxide = 34.0147 g/mol
The mass of hydrogen in the solution can be calculated thus :
Number of moles of hydrogen peroxide × Molar mass of hydrogen peroxide Mass of hydrogen = 0.95 mol × 34.0147 g/mol = 32.314 gTherefore, the bottle contains 31.314 g of hydrogen peroxide per Litre of the solution.

6.11
7.68
3.08
2.35
4.07
Answers
Answer:
The correct answer is 7.68
Explanation:
Isoelectric point (pI) is the pH at which the amino acid has net a charge of zero. We have to choose the two values of pKa at which the neutral form of the amino acid is predominant. Histidine (Hys) is a basic amino acid. From pKa's data, we deduce:
pKa1 = 2.3 (corresponds to α- carboxyl group)
pKa2= 6.04 (corresponds to R group)
pKa3= 9.33 (corresponds to α- amino group)
Since it is a basic amino acid, the neutral form will exist between the higher pKa's values. Thus, the pI will be in a pH value between 6.3 and 9.33.
So, we have to calculate the average of pKa2 and pKa3:
pI= (pKa2+pKa3)/2= (6.04+9.33)/2= 7.68
Therefore, the pI of Hys is 7.68.

Answer:
The correct answer is : D. isoelectric line.
Explanation:
ECG interpretation requires the analysis of various waves and curves and their characteristic. There are different type of waves and curves that can be found and analyzed in ECG such as P- wave, T wave, PR interval and others.
All these curves and interval shows electrical activities generating by the repolarization and depolarization of atria and ventricles of heart.
Base line or isoelectric line shows a flat line which have no electric activity as there is no negative or positive charge to create deflection.
Thus, the correct answer is : D. isoelectric line.
How useful is the cell type in classifying organisms?
Answers
Answer:
without cell type u cannot classifiy organisms
The cell type is extremely useful in the classification of organisms. This is because the cell type distinguishes the structural morphology and functional property of an organism with respect to its phenotypical features.
What is Cell type?Cell type may be defined as a group of cells that possess a common transcriptomic signature and low variation in other phenotypes. Cell types are utilized in order to identify cells on the basis of their morphological or phenotypical features.
It is only the cell types that enable people to understand and estimate how a complex organism evolved from a simpler organism. It also allows us to understand and study on the basis of their features, similarities, dissimilarities, etc. among diverse organisms.
Cell types also provide us with a brief evolutionary history of the organisms and the other organisms that are closely associated with them.
Therefore, the cell type is extremely useful in the classification of organisms.

Explanation:
A statement describe constructive forces is a volcano erupts, a river deposits gravel at a bend , plate movement creates mountains.
What is constructive force?Constructive force is defined as a method of raising or constructing the Earth's surface features. The planet undergoes constructive processes when events take place that improve or transform it. The procedure by which sand is dumped upon a river bank by the flowing water is an illustration of a constructive process. The river bank is raised as a result of this construction.
Mountains and land are formed throughout time by volcanic activity. inside a volcano, heated, molten rock. On the surface of the Earth, lava flows from the volcano. Igneous rock is created as it cools. The deformation of the crust, volcanic eruptions, and sediment deposition are three of the primary constructive factors. Crustal deformation is the alteration or deformation of the shape of the land. The shifting of the Earth's plates is one of the key causes.

The human genome contains approximately 10 6 copies of an Alu sequence, one of the best-studied classes of short interspersed elements (SINEs), per haploid genome. Individual Alu units share a 282-nucleotide consensus sequence followed by a 3'-adenine-rich tail region (Schmid, 1998). Given that there are approximately 3×109 base pairs per human haploid genome, about how many base pairs are spaced between each Alu sequence?
Answers
Answer:
3000
Explanation:
- Human haploid genome >>> 3 x 10⁹ base pairs >>> 3,000,000,000 base pairs
- Human haploid genome >>> 10⁶ copies >>> 1,000,000 Alu Transposable Elements
- Space between each Alu Transposable Element (TE) >>>
3,000,000,000 base pairs / 1,000,000 Alu elements = 3,000 base pairs
Alu elements are highly repetitive DNA sequences that account for approximately 20% of the human genome. These sequences (Alu) are considered to be non-autonomous Transposable Elements (TEs) capable of transposing within the genome via an RNA intermediary.
