why old system of measurement isn't accepted nowadays
why velocity is regarded as a vector quantity?
Answer:
Because velocity has magnitude and direction, speed is not a vector quantity since it only has magnitude
For example, if a car is moving backwards with a speed of 40m/s
Your velocity is - 40m/s
Speed is 40m/s

When a car drives down a street, what energy conversions are happening?
A. The stored energy of the gasoline is converted to the potential
energy of the car.
B. The kinetic energy of the gasoline is converted to heat and the
kinetic energy of the car.
C. The kinetic energy of the gasoline is converted to heat.
D. The potential energy of the gasoline is converted to heat and
kinetic energy
Answer:
it is D
Explanation:
The gasoline fuel used inside the car has inherent potential energy in its molecules. When the car is started, this potential energy will be converted to heat energy. The heat energy will then be used to carry out mechanical works in the engine of the car, this makes the car to move forward.

what is the function of the Vaseline
Answer:
Chesebrough noticed that oil workers would use a gooey jelly to heal their wounds and burns. He eventually packaged this jelly as Vaseline. Petroleum jelly's benefits come from its main ingredient petroleum, which helps seal your skin with a water-protective barrier. This helps your skin heal and retain moisture.
Explanation:
hiiiiii
Answer:
Explanation:
What Vaseline does is seal existing moisture into your skin. It also protects skin that's been injured or irritated by forming a seal or barrier where it's applied. With this barrier, petroleum jelly effectively reduces how much moisture is lost from the skin.
If the symbol “→” means “are made of”, which of the following answer choices correctly demonstrates the relationship between the given terms? (1 point)
Cells → Tissues → Organs → Organ Systems
Organ Systems → Organs → Tissues → Cells
Organ Systems → Organs → Cells → Tissues
Tissues → Organ Systems → Cells → Organs
Answer:
Organ Systems → Organs → Tissues → Cells
Explanation:
Just took the Quick Check
The option that best demonstrates the relationship between the level of organizations of life if the symbol → means "are made of" is Organ Systems → Organs → Tissues → Cells
LEVEL OF ORGANIZATION:
All living organisms are made up of cells, which is the smallest or simplest unit of life.
However, CELLS of similar functions come together to make up the TISSUES, tissues come together to make up ORGANS and organs that perform similar functions come together to make up ORGAN SYSTEMS.
Therefore, if the right arrow symbol (→) means "made up of", the best and correct representation of life is:
Organ Systems → Organs → Tissues → Cells

2 characteristics of bisexual flowers

Explanation:
Describe the cell structure of fungus in detail with a neat labeled diagram.
Answer:
Fungal cells differ from mammalian cells in that they have cell walls that are composed of chitin, glucans, mannans, and glycoproteins. Both mammalian and fungal cells have cell membranes; however, they differ in their lipid composition.
Explanation: Like plants and animals, fungi are eukaryotic multicellular organisms. Unlike these other groups, however, fungi are composed of filaments called hyphae; their cells are long and thread-like and connected end-to-end, as you can see in the picture below.

Ecology is the study of how: Group of answer choices people interact with their environment. the lithosphere, biosphere, and hydrosphere interact with each other. pollution reduces the productivity and health of the environment. organisms and populations of organisms interact with one another and with the nonliving components of their environment.
Answer:
Biosphere, relatively thin life-supporting stratum of Earth’s surface, extending from a few kilometres into the atmosphere to the deep-sea vents of the ocean. The biosphere is a global ecosystem composed of living organisms (biota) and the abiotic (nonliving) factors from which they derive energy and nutrients.

You are trying to determine if an object is living or nonliving.
Which characteristic(s) would you expect to observe in order to
classify the object as a living thing?
SELECT ALL THAT APPLY
a The object grows and develops.
b The object moves.
c The object reproduces.
d The object maintains homeostasis.
e The object is made of one cell.
Answer: a,b,c,d
Explanation:
all four of them are characteristics in all living organisms. All living things will grow and change, it will move otherwise it wouldn’t be able to get the nutrients it may need (or run away from predators), in order for the species to go on, they must reproduce, and they must maintain homeostasis so that they don’t freeze of burn to death. but however, it is not required for the living organism to be made up of only one cell, take humans for example.
The correct characteristics of a living thing are:
a The object grows and develops. c The object reproduces. d The object maintains homeostasis.There are several traits used to classify objects or things normally as living things and objects or things without these traits are classified as non-living. The some of characteristics of living organisms are:
consist of one or more cells reproduction homeostasis metabolism response to stimuli or environment growth and developmentTransfer of genetic materialThere are some more traits that are not true for some of the organisms or living things.
Thus, the correct answers are options: a, c, and d.

Write a report on the origin of life.
Take a subject of origins or a question you have and write a minimum of 500 words as a research project. Be sure to list all references and resources as part of your bibliography. Other information can be found at a library or other reference sources.
The origin of life is a very complex story. According to some religions, people say that there is a higher being who created the creatures on the earth, and the earth. Science claims many different theories, that we descended from monkeys and apes. Truthfully though, these are all just theories.
(This is just a snip bit of the possible theories you could use.)

Explain the difference between transverse wave and longitudinal wave.
Answer :
Transverse wave is a wave which vibrates or oscillates at right angles to the direction the wave or energy is moving
Examples : light waves abd waves that are traveling on the surface of the water.
Longitudinal waves is a wave which vibrates or oscillates to the direction the energy or wave is moving
Example : sound waves
Answer:
» A transverse wave is made up of crests and troughs at maximum displacements hence vibrating energy at right angles, where as a longitudinal wave is made up of compressions and rare factions where energy is assigned and kept in those particle density regions
