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
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

An element has an atomic mass number of 16 and an atomic number of 7. The element has _ protons and _ neutrons
Answer:
7 protons and 9 neautrons
Explanation:
neautrons = atomic mass - atomic number
16-7= 9
protons= number of electrons= number of protons (this can be seen in the atomic number)
The DNA sequence of a gene for a protein:______.a. mutates at a high rate.b. is a polymer of four ribonucleotides.c. ultimately determines the amino acid sequence of a protein.d. is a non‑linear code.
Answer:
The correct answer is : Option C. ultimately determines the amino acid sequence of a protein
Explanation:
DNA sequence is destined to make a specific amino acid chain of a particular protein through the process of transcription and translation. These two process together known as the protein synthesis.
DNA sequence makes the mRNA sequence and this mRNA sequence with tRNA and ribsomes are used to form the sequence of the amino acid chain of a protein during protein synthesis.
Thus, the correct answer is option C.

Explanation:
what is the maxium temperature reached when you combine 25 grams of zinc with hydrochloric acid?
Answer:
The approximate value for the maximum temperature reached during this reaction will be 87.1 °C (option E).
Explanation:
Zinc is a reactive metal so it will strongly react with the hydrochloric acid, which also is a strong acid and so it is highly reactive too. This will result in an exothermic reaction (one where heat is given off to the surrounding).
The products of this reaction will be hydrogen gas and aqueous zinc chloride (replacement reaction).

Many properties of living things involve the transfer and transformation of
energy and matter. For example, plant chloroplasts convert energy from sunlight
to which of the following forms of energy or matter? (From Topic: 1.1 The study
of life reveals unifying themes)
the energy of
motion
kinetic energy
carbon dioxide
and water
oxygen
chemical
energy
Answer:
Oxygen and chemical energy
Explanation:
In the thylakoids of the chloroplast6CO2 + 6H2O (In the presence of light) → C6H12O6 (Sugars) + 6O2.Plants make their own food. The chemical reaction for this process is shown
in the equation below.
CO2 + H2O + energy → C6H12O6 + O2
What are the products in this chemical reaction?
O A. CH1206 + energy
O B. H2O + energy
O c. C&H 206 + O2
O D. CO2 + H20
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.

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?
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.

Two important polysaccharides made up of glucose monomers are _______ and _______.
Answer: cellulose and starch
Explanation:
polysaccharides are large molecule that are made up of many monosaccharides this include simple sugars, like glucose. Small mononers are usually binded by enzymes to create a polysaccharide. Examples of polysaccharides are Starch, glycogen, cellulose.
Plants synthesize glucose a type of sugar and it excess is stored as starch. Starch is therefore the stored form of sugars in plants and it consist of glucose monomers that are joined by α1-4 or 1-6 glycosidic bonds.
Cellulose is found in the cell walls of plant and its provides support . It is abundant natural biopolymer.

Which of the following ECG components represents a lack of electrical activity? A. T-wave B. Q-T interval C. P-R interval D. Isoelectric line
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 does a swim bladder help the ray-finned fishes maintain buoyancy?A. Gas is added to the bladder as the fish's depth increases.B. It removes oxygen from the water and stores it.C. It removes water from the digestive tract.D. It adds and removes salt from the water stored in the bladder, which changes its density and thus its buoyancy.E. Gas is removed from the bladder as the fish's depth increases.
Answer:
A. Gas is added to the bladder as the fish's depth increases.
Explanation:
The swim bladder is a gas-filled organ localized in the dorsal region of Osteichthyes (bony fish) that allows them to regulate buoyancy, thus maintaining water depth without swimming. Since the swim bladder localizes in the dorsal region, it also functions as a stabilizing organ. This organ is composed of two sacs whose walls contract and expand in response to water pressure. The swim bladder contains an oval window that enables to adjust buoyancy in order to maintain a constant depth, or to ascend or descend in a wide range of water depths.
Eventually the weight will stop moving. Why? Where does the energy go?
Answer:
the energy is lost due to friction or air resistance or any opposing or resisting forcw for that matter
Answer:
There are many reason why something will stop moving. For example, if you throw a ball up into the air it reaches a max where it stops due to both gravity pulling it down and the air resistance that the ball is experiencing.
Another example is if a car is driving on a flat road and the driver takes the foot off the gas the car will come to a stop after some time due to the friction that is being caused by the road. The energy from the tire would get consumed as friction occures between the road and tire where the enegery would be transferred to the road.
