Answer: The average speed of the toy car during the two trials is 2m/s.
Explanation:
Speed can be defined as a type of scalar quantity in physics through which the rate at which an object travels through a distance is measured in a given amount of time. The formula for determining the speed of a car is:
Speed= distance/ time which has an SI unit of m/s.
From the speed tests carried out on a toy car, the speed of trial 1 is:
Distance= 10 meters
Time= 5 seconds
Therefore trial one speed is 10/5= 2m/s
While the speed of trial 2 is:
Distance= 40meters
Time= 20 seconds
Therefore trial 2 speed is 40/ 20= 2mls
Average speed of the toy car during the two trials is: Sum of both both speeds divided by total number of trials.
Therefore: 2 m/s + 2m/s / 2= 2m/s
From the calculation, the average speed of the toy car during the two trials is 2m/s.
Why is protein synthesis different in prokaryotes and eukaryotes
Answer:
A few aspects of protein synthesis are actually less complex in eukaryotes. In prokaryotes, mRNA is polycistronic and may carry several genes that are translated to give several proteins. In eukaryotes, each mRNA is monocistronic and carries only a single gene, which is translated into a single protein.

Summarize in 2-3 sentences the process of photosynthesis
Answer:
Photosynthesis is a chemical reaction where plants take in carbon dioxide (CO2) and water (H2O) through its stomata. With the help of sunlight and chlorophyll, which is found in its chloroplast, it is used to produce glucose (C6H12O6) and oxygen (O2). It converts light energy (sunlight) to chemical energy.
Explanation:
Answer:
please mark me brainlest!!
Explanation:
photosynthesis, plants take in carbon dioxide and water from the air and soil. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) generation of ATP, and conversion of CO2 into carbohydrates (carbon fixation).
Where are the tectonic plates located?
Answer:
The outermost part of Earth's structure is known as the lithosphere. The lithosphere consists of the crust and small portion of the upper mantle. The lithosphere is divided into a number of tectonic plates. These plates move and interact with one another, driven by convectional forces within the Earth.

What type of population growth does the graph show? How do you know?
Answer:
Logistic growth
Explanation:
The curve has a period of exponential growth, but then levels off at a stable size. growth whose rate becomes ever more rapid in proportion to the growing total number or size.
Some proteins, like Response area, have the function of Response area. Nucleic Acids, like Response area, are responsible for Response area. Carbohydrates provide Response area for cells, and Response area is a common carbohydrate. Lipids are used as Response area, and a Response area is an example of a lipid.

the graph shows the relationship between the number of cigarettes smoked per day and the increased risk of lung cancer what name is given to this type of correlation
Answer:
Positive correlation
Explanation:
When one variable increases, the other increases as well. In this case, a higher number of cigarettes smoked per day will see an increased risk of lung cancer as well.
The reactants for photosynthesis are carbon dioxide, water and sunlight (light energy).

HOPE THIS ANSWER HELPED :)Suppose the great, green galoofus lizard has 28 chromosomes in the nucleus of its unfertilized eggs. Predict how many chromosomes will be in the skin cells of a great, green galoofus lizard?
Answer: 56
Explanation:
Because an unfertilized egg has half the chromosomes of a fertilized egg. The fertilized egg then splits, and continues splitting until the lizard is born. Always remember, whenever a question talking about an unfertilized egg, it has half the chromosomes of a fertilized egg. One more side note, it doesn’t matter what body part you talk about. A skin cell will have the same number, and identical chromosomes compared to a heart cell. (So long as it’s the same organism, if it isn’t, but part of the same species, it will have the same number of chromosomes, but it may have a unique set of chromosomes). If you want me to go into detail, I can, just respond to this answer.

Explain how an imbalanced ecosystem be beneficial
Answer:
Ecological balance is a term used to describe the equilibrium between living organisms such as human being, plants, and animals as well as their environment. ... Therefore, this balance is very important because it ensures survival, existence and stability of the environment
Explanation:
If one species is lost the entire ecosystem can stop working. ... If something happens in an ecosystem, it can shift from a state of balance to a state of imbalance. Ecological imbalance is when a natural or human-caused disturbance disrupts the natural balance of an ecosystem.

As electrons move down the ETC, a H+ gradient is made.
The Krebs cycle produces ATP, NADH and CO2.
H+ pass through the ATP synthase to make ATP.
NADH gives electrons to the ETC.
In glycolysis, glucose is split into two pyruvate and makes some ATP.
Answer:
- In glycolysis, glucose is split into two pyruvate and makes some ATP
- The Krebs cycle produces ATP, NADH and CO2
- NADH gives electrons to the ETC
- As electrons move down the ETC, a H+ gradient is made
- H+ pass through the ATP synthase to make ATP
Explanation:
This question is describing the processes involved in cellular respiration. Cellular respiration is the way through which living cells synthesize energy (ATP) by breaking down sugar. Cellular respiration involves three major steps: glycolysis, Krebs cycle, and oxidative phosphorylation (electron transport chain).
- Glycolysis is the process whereby glucose is broken down into pyruvic acid or pyruvate with the synthesis of net 2 ATP molecules.
- Kreb's cycle produces ATP, NADH and CO2.
- NADH is an electron carrier that donates electrons to the Electron transport chain (ETC).
- Electrons move down the ETC to produce a proton (H+) gradient
- The proton (H+) passes through an enzyme called ATP synthase to make ATP from ADP molecule.

First correct answers get Brainlies. Spam answers get flagged.
New Zealand has a population of 4,326,380 and has an area of 103,736 miles squared while Australia has an area of 2,967,909 miles squared and a population of 21,905,140. Explain how New Zealand can have a larger population density than Australia even though it has a smaller total population.
The reason they have a higher population density is because they have more people on average in a certain area, because New Zealand is smaller they are given less space to live, this means that more people are crammed together, making the density of people within a square mile higher. When you give less square miles, you reduce the amount you have to divide the population by, which makes the density go up.
( In case you wanted the calculations for the density on New Zealand and Australia, it is about 41 to 42 people a square mile in Zealand, and maybe 7 or 8 per square mile in Australia.)
