Answer:
Compared to the use of many gasoline vehicles with only one person per vehicle, this method of transportation conserves more fossil fuels.
Explanation:
A form of transportation —such as the subway or streetcar— has capacity for many passengers and uses electricity as an energy source. This means fewer people using gasoline-vehicles, which leads to savings in fossil fuels, such as gasoline or diesel.
The decrease in the use of fossil fuels in vehicles has been proposed as an alternative to reduce environmental pollution and its consequences. One alternative is to consider mass transport vehicles that use alternative energy, a sustainable form of transport.
None of the other options are correct, as they involve more or the same use of fossil fuels per person.
What type of electron is available to form bonds?
Answer:
The electrons that are available to form bonds are known as valence electrons.
Explanation:
The electrons that are available to form bonds are known as valence electrons. I hope this answer is helpful.
The type of electron available to form bonds is a valence electron
What type of electron is available to form bonds?Valence electrons are the electrons in the outermost energy level or shell of an atom. These electrons are involved in the formation of chemical bonds between atoms.
Valence electrons are responsible for determining the chemical properties and reactivity of an element. When atoms come together to form chemical bonds, they do so by sharing, gaining, or losing valence electrons. The interaction of valence electrons between atoms allows for the formation of covalent bonds, ionic bonds, or metallic bonds, depending on the specific circumstances.
Therefore, valence electrons are crucial in the process of bonding between atoms.

Which of the following is NOT a characteristic of all living things?
Ability to reproduce
Ability to move
O Growth and development
Homeostasis
Answer:
homeostatis
Explanation:
The answer should be homeostatis. Organisms can not do this.
Answer:
Ability to move
Explanation:
All organism species have the ability to reproduce, grow and develop, and maintain homeostasis (for example, sweating). Not all organisms can move, however. Cacti, for instance, are stiff and do not move on their own, yet are still alive.
Which type of energy change causes this leaf to grow? A. Thermal energy is transformed into potential energy. B. Thermal energy is transferred to the leaf. C. Electromagnetic energy is transformed into chemical energy. D. Electromagnetic energy is transferred to the leaf.
Answer:
C. Electromagnetic energy is transformed into chemical energy
Explanation:
Growth is one of the characteristics of living things. It refers to the increase of an organism. A leaf is part of a plant, which is a photosynthetic organism i.e. an organism capable of producing its own food using energy from sunlight. Light energy is a part of the ELECTROMAGNETIC ENERGY.
This light energy is used to synthesize glucose (food) via photosynthesis. The glucose, which stores chemical energy in its bond is then broken down to yield ATP used for growth. Hence, the transformation of electromagnetic energy to light energy is how a leaf grow.
it is C. Electromagnetic energy is transformed into chemical energy.

A student wants to investigate the force of gravity. The student has an apple and a marble. What would be the best way for the student to use these materials? Place the apple on the floor. Roll the marble so it hits the apple. Put both objects on a desk. Push them forward at the same time. Hold both objects at the same height above the floor. Drop them at the same time. Place the marble on a desk. Place the apple next to the marble so the objects touch.
Answer:
Put both objects on a desk
Explanation:
The best way to use the materials to investigate the force of gravity would be to put both objects on a desk. The force of gravity can thus be obtained by measuring the distance between the objects as well as their masses.
According to Newton's law of universal gravitation, the force of gravity (F) between two objects is directly proportional to the product of their masses (m and M) and inversely proportional to the square of the distance (d) separating them.
Mathematically,
F = G [tex]\frac{mM}{d^2}[/tex] where G is a constant.

How does mutation increase chances for survival? Please help me.
Answer:
These mutations can increase an organism's chance for survival and usually occur over a course of many generations producing offspring (or babies) with the helpful mutation. ... This would allow you to mate and produce offspring because you would have survived for longer lifespans.

Using the law of conservation of mass, what is the mass, in grams, of the product in the given reaction?
Reactant 1 (35 grams)+ Reactant 2 (115 grams) →Product (? grams)
A. 80
B. 140
C. 150
D. 75
Answer:
The correct option is;
C. 150
Explanation:
By the law of conservation of mass we have that in a closed system, the mass of the items in the system can not be destroyed or created by a physical process or chemical reaction
In the given chemical reaction process we have;
Reactant 1 (35 grams) + Reactant 2 (115 grams) → Product = ((35 + 115) grams)
∴ Reactant 1 (35 grams) + Reactant 2 (115 grams) → Product (150 grams)
The mass of the product = 150 grams.

How do the circulatory and nervous systems work together to maintain homeostasis | ASAP
Answer:
The circulatory and the nervous systems work together to maintain homeostasis because the circulatory system gives your brain a lot of oxygen and glucose while your brain regulates your heart rate and blood pressure. Meanwhile, your bones are busy making new blood cells. Working together, these systems maintain homeostasis.

b) How does the thermal energy of solid water change as it melts?
Answer:
Hi! So solid water would be ice, the particles in ice are very close together which makes it firm and makes it ice. When you put the ice in the microwave, (Microwave has heat so it would be thermal energy!) the particles in the ice mover a tiny bit away from each other which then makes it water. Then, if you boil the water, the particles that are in the water move far away from each other and it turns into steam!

Ivan reads a story about a population of mice that become stranded in a dark jungle. Some mice are dark brown, while others are white. According to the process of natural selection, predict which mice would be more successful living in a dark jungle. Explain natural selection and your prediction.
Answer:
The dark brown mice would be more successful in a dark jungle since the darker color of their fur would make it hard for predators to spot them.
The process of natural selection, predict which mice would be more successful living in a dark jungle is de dark brown.
What is natural selection?Natural selection is one of the main mechanisms of evolution. In a very simple way, we can say that natural selection is a process in which the fittest organisms are selected, survive in the environment, reproduce and pass their characteristics on to their descendants.
In this case, as it is a very dark forest, an animal with a white coat will attract more attention while an animal with a dark brown color will only be camouflaged in the environment.

Summarize the process of sexual reproduction and explain how variations of inherited traits can increase or decrease an organism’s chance of survival
Answer:
Explanation:
A Human cell has 46 chromosomes. (I’ll use humans to keep things simple). In sexual reproduction both humans have 23 chromosomes, in their sex cells. (Men have 23 in a sperm and women have 23 in an egg cell). These half cells merge to create 1 unique cell, that has characteristics of both male and female. The cells multiply and then a baby is born with a unique set of genes. These cause variations, and remember these variations can carry from generation to generation. As for how variations can increase a chance for survival, variations allow unique gene sets to be made, so that in case of a disease (in this case I’ll use a disease, but it could also include harsh environmental conditions), these unique gene sets may give an individual natural immunity to the disease. How can a variation decrease an organisms chance for survival? Well, s there are many ways that a unique gene set can make it difficult to survive. For example a genetic disease your family has had a history with. These diseases include, but are not limited to, cancer, diabetes, and schizophrenia.
