What are atoms? What particles are they composed of? What is relative location and charge of each particle?
Explanation:
an atom is the smallest chemical particle that exists
the are composed of 3 main things
protons
neutrons
electrons
protons and neutrons are located in the nucleus of the atomic structure( centre) and electrons are in shells out of the nucleus
protons are positive charged
electrons are negative charged
neutrons don't have a charge as their charge is too small and considered as nothing so 0
How are the krebs cycle and the electron transport chain related?
what is the highlighted number ?
Answer:
I think it is the atomic mass, or the atomic weight.
Explanation:
The number above the symbol is the atomic mass (or atomic weight). This is the total number of protons and neutrons in an atom. The number below the symbol is the atomic number and this reflects the number of protons in the nucleus of each element's atom.

A large number species on Earth become extinct during a short time period about 65 million years ago. Based on this pattern of extinction, which is the MOST likely cause
Answer and Explanation:
During the whole biota history, there occurred extinctions due to different reasons.
During the Cretaceous, which took place between 145-65 million years ago, there occurred a massive extinction that eliminated most of the species on the Earth. Many of the characteristic groups of this period were affected. Dinosaurs, Plesiosaurs, Ammonites, Tricodonts, Cycas, Gynkgos, Conifers, the recent angiosperms, birds, and mammals.
The extinction was caused by the volcanic eruptions, and the unusual fall of many different asteroids, which caused important changes on the Earth´s surface. The consequent climatic change was what ended affecting all the species directly. The extinction was gradual, although it occurred in a short geological lapse of time.
Co..me up with your own example of a stimulus and response with living organisms
.
Answer:
A crocodile goes into the shade when the temperature goes high.
An example of a stimulus and response with living organisms is as follows:
Whenever any living organism is exposed to a warm or hot object it immediately pulls back its own body from this point of contact. This is also called as reflex action. What is a Stimulus?A stimulus may be defined as a type of thing or event that immediately provokes a specific functional reaction by an organ or tissue in response to a specific treatment.
The information that living organisms perceive from the external world is sensed by the sense organs then with the help of nerves it sends to the brain which stimulates a specific action and sends messages to the body to react in a particular way with the respect to the stimulus.
Therefore, an example of a stimulus and response with living organisms is briefly mentioned above.

What is the correct answer?
Answer: Answer is B
Explanation:
Which cell has the GREATEST surface area to volume ratio?
O Chicken egg
O Skin cell
O Bacterial cell
O Liver cell
The cell with the greatest surface area to volume ratio is the smallest cell, in this case, the bacterial cell.
As a cell increases in size, the proportional increase in volume is higher than that of its surface area. This tells us that the bigger a cell becomes, the lower its surface area to volume ratio will be.
The chicken egg is just one large cell, the largest cell produced by most animals. The skin and liver cells are much smaller, measuring roughly 25-30 micrometers. However, the smallest of the list by far is the bacterial cell, measuring a mere 1-3 microns. This size tells us that the greatest surface area to volume ratio belongs to the bacterial cell.

Different between the two types of reflection regular reflection and irregular reflection? "plz help me am new here"
Answer:
The light reflection is the returning back of light waves in the same medium on meeting a reflecting surface, and the surface at which the reflection takes place is called the reflecting surface, The light reflection is classified according to the nature of the reflecting surface into the regular (uniform) reflection, and the irregular (non-uniform) reflection.

The DNA sequence that makes up the genetic code of an organism determine which traits the organism will exhibit
Answer:
How are the instructions coded by DNA translated into an organisms physical traits. They are translated into proteins which express an organism's physical traits. In DNA, the structure and size of the four nitrogen bases allows only for one kind of base to pair with one other kind. This is called the base-pairing rule.

ment is always true of work?
A) It is difficult.
B) It involves levers.
C) It involves a transfer of energy.
D) It is done with a machine.
Answer: C. It involves a transfer of energy.
Using the scientific definition, the statement that is always true of work is it involves a transfer of energy. The correct option is C.
What scientific theories?Scientific theories are the theories that are given by scientific facts and information. These theories are based on observation of natural things and places.
There is the transfer of energy in the natural world. Every organism and plant is connected with each other in the form of a transfer of energy. This is called a food chain.
In the food chain, the organism is divided into different levels. These levels are based on their food. They are autotrophs, heterotrophs, and decomposers. Autotrophs have the largest amount of energy.
Thus, the correct option is C) It involves a transfer of energy.

Which is the process by which gas exchange between the respiratory system and the blood cells in the cappilaries occurs? transfusion condensation evaporation diffusion
Answer:
Diffusion
Explanation:
Diffusion is the process by which molecules of substances move from regions of higher concentration to regions of lower concentration until equilibrium concentration is attained. This movement of molecules is because a concentration gradient exists between the two regions.
Blood cells in the capillaries is low in oxygen because the cells have used up the oxygen in cellular respiration. However, in the lungs, the oxygen concentration is high due to inspiration of oxygen from the external environment. Therefore, a concentration gradient exists between the lungs and blood cells in the capillaries. Oxygen from the lungs diffuses into the blood cells in the capillaries, and these blood cells are then returned to other parts of the body by the circulatory system. This is a continuous process and is known as gaseous exchange.
Answer:
Diffusion

"Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits. He recognized the mathematical patterns of inheritance from one generation to the next."
Through his work, Mendel published his experiments to explain his findings.
What did his laws of inheritance state?
A.Parental genes are randomly separated from the sex cells so that sex cells contain only one gene of the pair.
B.Each trait of an organism can contain multiple alleles of that trait.
C.Organisms with alternate forms of a gene will express the dominant form of the gene.
D.The inheritance of one trait is not dependent on the inheritance of another.
E.Genes can be transferred from the parent generation directly to the offspring based on the environmental factors surrounding the offspring.
