What is energy? Give an example of how energy is used in a living organism.
Answer:
Energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another. Organisms use energy to survive, grow, respond to stimuli, reproduce, and for every type of biological process. The potential energy stored in molecules can be converted to chemical energy, which can ultimately be converted to kinetic energy, enabling an organism to move.
Explanation:
Energy is defined in the scientific community as the capacity to perform work.
What is Energy?Molecules need energy to be broken down, built up, and transported across plasma membranes.
Energy is required for all life's work. A significant amount of energy is also simply wasted as heat to the environment. The story of life is one of energy flow, including how it is captured, transformed, used for work, and lost as heat.
Because energy can never be regenerated (unlike matter), it is constantly needed by living things.
Therefore, Energy is defined in the scientific community as the capacity to perform work.

If a DNA molecule consists of 29% Guanine, how much cytosine will it contain?
Answer:
Chargaff's rule: C=G => answer is 29%
Explanation:
The percentage of cytosine contained in the DNA molecule = 29%
According the Chargaff's rule the percentage of Cytosine contained in a DNA molecule will be equal to the percentage of Guanine contained in the DNA molecule.
From the question the percentage of Guanine that is contained in the DNA molecule is 29% therefore the percentage of Cytosine that will be contained in the DNA molecule will be = 29%
Hence we can conclude that the percentage of cytosine contained in the DNA molecule is 29%

Some plants have leaves that are poisonous to some animals. Which kind of adaptation is this? (1 point)
Survival
reproduction
respiration
defense
Answer:
this is for defence
Explanation:
Defense is mechanism of adaptation by which some plants have leaves that are poisonous to some animals.
Poisonous plants are those herbs, flowers, shrubs or fruits that are toxic enough to harm the body of people as well as dogs, cats and other animals.
The defense mechanisms that plants have developed are very varied and among them are physical adaptations such as thorns or the synthesis of chemical substances that can inhibit consumption by predators and some with antimicrobial effects.
During the evolutionary process, all organisms have been attacked by viruses, bacteria and fungi; likewise, they are consumed as a source of nutrients by different herbivorous animals and vertebrates.
In response to external factors that limit the normal development of plants, they have developed various defense mechanisms ranging from anatomical adaptations to chemical defense.
The chemical substances produced by plants as defense, are very varied, have different functions, inhibit the action of pathogens and prevent their attack, others cause negative effects at different levels, such as irritation on contact, nausea or gastric disorders.
Some of these compounds are saponins, phenolic compounds that include phenolic acids, and complex polymers such as tannins and lignin have the ability to cause pharmacological and toxicological effects in animals.
Therefore, we can conclude that plants have developed various defense mechanisms as chemical defense by which some plants have leaves that are poisonous to some animals.

What is solar system ?The solar system is a large with approximate size at least 100 astronomical units in size held together by the sun’s immense gravitational pull that keeps the planets and the asteroids in orbit
The solar system have 8 planets which revolve around the sun in an elliptical paths known as orbits where The earth is also one of the planets and lies at a distance from the sun.
These planets were formed at least 4.6 billion years ago where discs of dust and gas orbiting around the sun followed by collapse and clumping together due to gravity.
There are two types of planets are observed such as Rocky planets include Mercury, Venus, Earth, and Mars as these are made up of solid rock and metal; Gas giants include Jupiter, Saturn, Uranus, and Neptune

Answer:
Explanation:
The reactants for cellular respiration are the products of photosynthesis. The products of cellular respiration are the reactants in photosynthesis.
During photosynthesis, green plants manufacture their food using sunlight to synthesize glucose from water and carbon dioxide. The other product of the process is oxygen gas. During cellular respiration, the glucose is combined with oxygen to produce energy, carbon dioxide and water.Which molecules are able to pass through the semipermeable membrane? Justify your answer
Answer:
hydrocarbons, oxygen, and water i think educated guess
Explanation:
Semipermeable membranes allow small molecules such as oxygen, water carbon dioxide and glucose to pass through.
What are the features of semi permeable membrane?Semipermeable membrane is a type of biological or synthetic, polymeric membrane that will allow certain molecules or ions to pass through it by osmosis.
Membrane separation processes use semipermeable membranes to separate impurities from water. The membranes are selectively permeable to water and certain solutes.
The semi-permeable membrane plays three important roles in EFGF devices: (i) isolating the separation channel from the electrodes, (ii) restricting movement of solutes of interest.

An airplane flying at a velocity of 610 m/s lands and comes to a complete stop over a 53 second period. a. Did this airplane speed up or slow down? Explain your reasoning. b. Did this airplane accelerate or decelerate? Explain your reasoning. c. Should your answer be positive or negative? Explain your reasoning. d. Calculate the acceleration.
Answer:
the airplane slowed down; it came to a stop over 53 seconds, which requires slowing. the airplane decelerated; decelerate is another word for slow down, it also is the opposite of accelerate. The answer should be negative; negative velocity is slowing down. And the acceleration is ~ -11.509 meters every second
Explanation:
the explanations are included in the answer.
Answer:
A) The airplane slowed down. It states that the plane lands and come to a complete stop over a 53 second period.
B) It decelerates. The speed doesn't increase. It slows down.
C) The answer should be positive. Although the deceleration is slowing down the plane, it's not going at a negative speed.
D) The answer is 11.5m/s. I divided the velocity by the amount of seconds it takes to make a complete stop.

What would happen if the members of one homologous pair did not segregate to opposite poles, but instead both went to the same pole
Answer:
Daughter cells with abnormal number of chromosomes will be produced (aneuploidy)
Explanation:
Ideally, homologous pair of chromosomes are meant to separate into opposite poles during the anaphase I stage of meiosis. However, a failure to separate, a process called MEIOTIC NON-DISJUNCTION, will cause some daughter cells to have more than the required/normal chromosome number while some daughter cells will have less than the normal or no chromosome.
This abnormality in chromosome number caused by failure of chromosome to separate is called ANEUPLOIDY. In a nutshell, when this occurs, the daughter cells will possess abnormalities in chromosome number i.e trisomy, monosomy etc.
