why don't birds get electrocuted when they land on an electric wire?
please help me out :-)
Answer:
Electricity flows by the movement of electrons through conductors. If a bird perches on a wire with two feet there is no motivation to go through the birds' body so electrons choose the path of least resistance and continue to flow along the wire.

what is needed for dna replication
Answer:
enzymes
ATP energy
nucleotides
Explanation:
All of the above are needed. Nucleotides are the basic building blocks of new DNA, ATP energy is needed because replication is an active process, and enzymes catalyze the reactions needed to carry it out (e.g. helicase to separate the strands to be replicated, DNA polymerase to build the new strands, and ligase to "glue" the fragments together).
Sedimentary rocks form from rock and mineral fragments, and metamorphic rocks form from existing rock.
True
Or False
Answer:
True
Explanation:
Sedimentary - A rock formed as a result of the weathering process, either by compaction and cementation of rock mineral fragments, or the precipitation of dissolved minerals.
Metamorphic - These rocks form as existing rocks are subjected to intense heat and/or pressure, usually over long periods of time.

Which statement best describe a chromosome?
A. It is a single piece of DNA that contains genes.
O B. It forms the hereditary material of all life on Earth.
OʻC. It is the passing of characteristics from one generation to the next.
O D. It is the part of a chromosome that ties together two chromatids.
Answer: A
Explanation: It most definetly not B, becuase not every form of life has DNA. A chromosome is a single chain of DNA that is coiled and super coiled to form dense thread-like pieces. The term chromosome is derived from the Greek words "chroma" or color and "some" or body and is so named because chromosomes have the ability to be stained with dyes.

A car with a mass of 2000 kg and a boat with a mass of 500 kg are both moving at the same speed.
What is the ratio of the kinetic energy of the car to the kinetic energy of the boat?
A. 2:1
B. 4:1
C. 9:1
D. 16:1
Answer:
B
Explanation:
Kinetic energy is possesed by a body by virtue of its motion. The ratio of the kinetic energy of the car to the boat is 4:1.
What is Kinetic energy?The term kinetic energy refers to the energy that is possesed by a body by virtue of its motion.
Now;
Kinetic energy of the car = 0.5 * 2000 * v^2
Kinetic energy of the boat = 0.5 * 500 * v^2
The ratio of the kinetic energy of the car to that of te boat is; 0.5 * 2000 * v^2/0.5 * 500 * v^2 = 4:1

The graph models the linear relationship between the water level of the river in feet and number of days the water level measured. Which function can be used to find y, the water level of the river after x days
Answer:
option 4, y=1/4x+16
Explanation:
to solve this you must find the slope and the y intercept.
slope is rise/run, and equal to 2/8 or 1/4
then, the find the y intercept, find where the line crosses the y axis. Here it is 16.
finally you plug these answers into the slope intercept form, y=mx+b. In this form, m= slope, x=days, and b= y intercept.
after you plug in your answers you are left with y=1/4x+16.
Which two major biological processes involved in the oxygen cycle are represented in the diagram? A. respiration and precipitation B. photosynthesis and evaporation C. photosynthesis and respiration D. evaporation and precipitation
Answer:
(c)
Explanation:
The two major biological processes involved in the oxygen cycle are Photosynthesis and Respiration.
Because of this, the byproducts of one system are the reactants in the other, which is how photosynthesis and cellular respiration interact. Oxygen and glucose are produced during photosynthesis by using the energy from sunshine, water, and carbon dioxide. The production of carbon dioxide and water during cellular respiration needs glucose and oxygen. The expression for photosynthesis is the inverse of the equation for cellular respiration, which serves as more evidence for this argument.What is Oxygen cycle?The layer of gases present above the surface of the world is called the atmosphere. A biosphere is comprised of all of Earth's ecosystems. The biggest oxygen reserve is located in the lithosphere, the solid outer layer of the globe that also includes the crust. The oxygen cycle is crucial to the continuation of life on Earth, together with the carbon and nitrogen cycles.This biogeochemical cycle shows how oxygen moves throughout the atmosphere, ecosystem, biosphere, and lithosphere. The carbon cycle is linked to the oxygen cycle.Mainly responsible for preserving the atmosphere's oxygen content is the oxygen cycle. The complete process can be summed up as follows: the oxygen cycle starts with photosynthesis, which takes place in the presence of sunlight, produces oxygen back into the atmosphere, allowing people and other animals to breathe in oxygen and exhale carbon dioxide, and then links back to the plants. This demonstrates the independence and connection of the oxygen and carbon cycles as well.To learn more about Oxygen cycle, refer to:

It moves perpendicular to the direction of the wave.
C
It has not affect on it
D
It may displace it temporarily, however when the wave passes the matter returns back
to its original position.
Answer:
The best and most correct answer among the choices provided by your question is the fourth choice or letter D "The thin membrane that closes the cavity of the middle ear from the outside changes position."
Your ears pop in airplanes because the air high above the surface of Earth is less dense than air near the surface, because air near the surface has all the air above it pushing down. Your inner ear has air trapped in it and as the atmospheric pressure changes, it causes pressure on your eardrum.

14. In the summary equation below, which process produced the lactic acid? enzymes glucose 2 lactic acid + 2 ATP
Answer:
Fermentation (anaerobic respiration)
Explanation:
Fermentation is also called anaerobic respiration, and it involves the breakdown of glucose in the absence of oxygen. Fermentation, which is carried out by some microbes, is named based on the type of product. There is alcoholic fermentation and lactic acid fermentation.
Lactic acid fermentation is the process whereby glucose is broken down to produce lactic acid. According to the summarized equation given in the question, lactic acid is formed by the enzymatic breakdown of glucose.
Enzymes + glucose → 2 lactic acid + 2ATP
Two ATP molecules and 2 lactic acid molecules are given as products in the reaction.

A patient has swollen feet, ankles, and legs, and has pain in his lower back. Tests show the level of urea, a waste product, in the patient's blood has suddenly risen. Which body system is most likely not functioning properly?
A.
Nervous
B.
Excretory
C.
Digestive
D.
Reproductive
The body system that is most likely not functioning properly is excretory system. The correct option is B.
What is excretory system?The excretory system is a detached biological mechanism that removes excess, unneeded materials from an organism's body fluids to help maintain internal chemical homeostasis as well as prevent body damage.
The excretory system's function is to remove waste from the body. Water, CO2, nitrogen, salts, and heat are among the wastes. Metabolism refers to the process by which the body converts food into energy.
The primary function of the kidneys is to eliminate excess water and wastes from the bloodstream through the production of urine, a liquid waste.
As the patient has swollen feet, ankles and legs and having urea level boosted in blood, it means his excretory system has some problems.
Thus, the correct option is B.
