Which parts of DNA provide the code for proteins?
Answer:
The genetic code is the sequence of nucleotide bases in nucleic acids (DNA and RNA) that code for amino acid chains in proteins. DNA consists of the four nucleotide bases: adenine (A), guanine (G), cytosine (C) and thymine (T). RNA contains the nucleotides adenine, guanine, cytosine and uracil (U).
A gene is a section of a DNA molecule that contains the information to code for one specific protein.
The DNA code contains instructions needed to make the proteins and molecules essential for growth, development and health.What is gene?A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. Many genes do not code for proteins.What is DNA?
DNA is the genetic material, which is involved in carrying the hereditary information, replication process, mutations, and also in the equal distribution of DNA during the cell division.

Which choice best describes the parts of the water cycle? The sun's thermal energy causes water on the earth to evaporate. The water vapor then condenses and forms precipitation. The precipitation then falls back to the surface of the earth. The ocean's tidal energy causes water to cycle on the earth. The water from the oceans evaporate and form precipitation. The precipitation then condenses back on the surface of the earth. The earth's magnetic energy causes water to evaporate. The water condenses into water vapor once it becomes precipitation. The condensation then falls back to the surface of the earth. The sun's thermal energy causes water vapor to condense. This condensation then forms precipitation. This precipitation returns to the atmosphere for the cycle to continue.
Answer:
The sun's thermal energy causes water on the earth to evaporate. The water vapor then condenses and forms precipitation. The precipitation then falls back to the surface of the earth.
Explanation:
The water cycle is an illustration of how water continuously moves or circulates between the atmosphere and the various parts of the earth.
Evaporation of water from the surface of the earth by the thermal energy from the sun causes water to leave the surface of the earth into the atmosphere. When the atmospheric water vapor (humidity) at the upper strata of the atmosphere becomes high, the vapor condenses to form clouds which later forms precipitation that falls back to the surface of the earth.
The ocean's tidal energy does not cause water to cycle on earth.

A mold is typically multicellular (has more than one cell) and filamentous in nature. The thallus of a mold consists of long, branched, threadlike filaments of cells called hyphae that form a tangled mass called a mycelium.
The thallus of a mold consists of long, branched, threadlike filaments of cells called Hyphae that form a tangled mass called a mycelium.

Determine the temperature of the bar on the fahrenheit scale.
Answer:
Determining bar temperature on Fahrenheit scale -
The temperature of the bar is given as 50 degrees Celsius.
If we know the temperature on the Celsius scale, we can convert it to the Fahrenheit scale.
We know
C / 5 = (F-32) / 9; Where C is the temperature on the Celsius scale and F is the temperature on the Fahrenheit scale.
Now,
50/5 = (F-32) / 9
Or, (F-32) / 9 = 10
Or, F-32 = 90
Or, F = 90 + 32
Or, F = 112 degrees Fahrenheit.
That is, the temperature of the bar on the Fahrenheit scale is 112 degrees Fahrenheit

Silicon Valley in the San Francisco Bay Area is often called the tech center of the world. The region gets its name from the silicon used in computer chips that were widely manufactured there. Today, this region houses many of the largest computer hardware, software, internet, and digital communication companies in the world. Identify and explain two ways in which an earthquake in this area could affect people in other parts of the world.
Answer:
One way an earthquake could affect people is by disrupting the electric power lines in Silicon Valley. A lack of power could disrupt or shut down major websites that people around the world rely on.
Secondly, an earthquake could cause severe damage to digital communication companies. If that happened, many businesses around the world would suffer. They might not be able to properly access, use, or update the computer applications they rely on for their businesses.

One way the earthquake could affect people is by damaging the electric power lines in Silicon Valley. A lack of power could mess up or shut down some of the websites that people all around the world rely on. Another way is an earthquake could cause a lot of damage to digital communication companies.

A cell removes a toxin it has produced through a chemical reaction. Which characteristic of living things is the cell demonstrating?
the ability to maintain homeostasis
the ability to maintain homeostasis
the ability to grow and develop
the ability to grow and develop
the ability to adapt and evolve
the ability to adapt and evolve
the ability to reproduce
Answer:
Sweating helps the human body maintain homeostasis by cooling the body when it starts to overheat so the internal temperature is kept more or less the same. When sweat evaporates from the skin, it uses up some of the excess heat energy on the skin, thus helping to keep the body cool.
According to cell theory, all living things are made of cells, and living cells come only from other living cells. Gene theory states that the characteristics of living things are controlled by genes, which are passed from parents to their offspring.
Sample answer: The concentration of oxygen in the atmosphere is maintained at 21 percent by a balance between two opposing processes: removal of oxygen from the atmosphere by most living things and addition of oxygen to the atmosphere by living things such as plants.
Sample answer: The human ability to sweat is an adaptation that helps maintain homeostasis in a hot environment by removing heat from the body when it evaporates. Like other adaptations, the ability to maintain homeostasis by sweating evolved by natural selection sometime in our evolutionary past.
a. Gene theory
b. Homeostasis
B
An adaptation is a trait that helps a living thing survive and reproduce in a given environment. Sample example. The chameleon’s ability to change color to match their background is an adaptation.
False
False
Humans began life as a single cell because we develop from a fertilized egg cell.
Gene theory states that genes are passed down from parents to their offspring. Genes determine the characteristics or traits of an organism. If these traits are particularly beneficial or adaptive, natural selection will cause the organisms with beneficial traits to produce more offspring compared to those without the beneficial traits. This results in a change in traits over time, which is called evolution.
No. Evolution is defined as a change in the characteristics of living things over time. Evolution through natural selection causes differences in the amount of offspring produced. Having offspring (or not) is, by definition, more than one generation.
Sample answer. I think that when ancestors of chameleons could change their color to match their background, they were less likely to be detected and killed by predators than those that couldn’t change their color. Therefore, the individuals that had the color matching ability were more likely to survive and reproduce than those that didn’t. This is an example of natural selection. Over time, this led to the population evolving the color changing ability, as those that didn’t have the ability died out.

which statement best describe the relationship between the products of photosynthesis and the reactants in cellars respiration
Answer:
Photosynthesis products serve as a chemical energy suppliers for reactants and cellular respiration.
Since photosynthesis creates oxygen and oxygen needed for cellular respiration in the production of carbon dioxide and energy, carbon dioxide is used to generate plant energy and oxygen.
Explanation:
Photosynthesis products produce chemical energy by reacting to cellular respiration. Photosynthesis products interact to extract ATP from cells in cellular breathing reactants.
Photosynthesis products inhibit the reactants in the presence of light in cellular breathing.
