Answer:
73%
Explanation:
Given: 27%
To find: Percentage of nitrogenous bases are cytosine
Solve: [tex]\frac{27}{100}[/tex] × [tex]\frac{100}{1}[/tex]
Firstly, divide 100% by thymine and cytosine
[tex]\frac{100}{2}[/tex] = 50
Now, If it is 50 / 50, but thymine has 27 then subtract 27 from 100
100 - 27 = 73
So, the percentage of nitrogenous bases are cytosine 73%
Select the correct answer. Which statement about natural selection is true? A. Natural selection and evolution are two terms for the same phenomenon. B. Natural selection is an outdated theory to explain how evolution took place. C. Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce. D. Natural selection is the process by which organisms develop variation in traits, which gives them a better chance of survival.
Answer:
C. Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce.
Explanation:
Natural selection is an evolutional process by which species of living organisms with stronger or more beneficial traits have higher chances of survival and reproduction. In other words, it is the process by which organisms adapt and survive.
Organisms in a population are all different in their own ways. And those with characteristics or traits better suited for the environment are more likely to survive than those without. The selection prefers more beneficial traits and not wholly on the superiority of the organism. So, the survival and reproduction chance of an organism depends on the presence of traits beneficial to the environment, which is how nature selects. And in this process, those selected will dominate the population while those rejected will be reduced or even die.
Thus, the correct answer is option C.
DNA is wrapped around
and condensed into chromosomes.
• Genes are used as a set of instructions to produce proteins.
Proteins affect the
and function of organisms.
Chromosome
Answer:
- DNA is wrapped around nucleosomes and condensed into chromosomes.
- Proteins affect the traits and function of organisms.
Explanation:
Nucleosomes are the basic unit of compaction of DNA. Each nucleosome is composed of ~148 bp double-stranded DNA and an octamer of histone proteins, which include two molecules of each core histone: H2A, H2B, H3 and H4. Subsequently, nucleosomes are packaged into chromatin fibers so they can be densely compacted into chromosomes. On the other hand, proteins are molecules that play important (structural and enzymatic) functions in a cell. These proteins may affect the structure/function of a cell, thereby affecting a certain characteristic/trait to develop.

List one organism and describe all of its adaptations.
Adaptation is a mechanism of species to survive and reproduce in their environments, adjusting to selective pressures. Cactus: leaves, stems, spines.
What is adaptation?
In biology, adaptation might be defined as the mechanism of organisms to improve their fitness in the environment in which they live, adjusting to different changes and selective pressures acting on them.
Adaptation involves molecular, physiological, morphological, and behavioral changes.
For these changes to persist and be transmitted from generation to generation, they must increase the individual's fitness. They must increase the individual survival and reproductive probabilities, making it more competitive.
A good and easy to unsderstand example of adaptation is the cactus.
Cactusses are plants adapted to dry and hot environments like deserts, where water availability is scarse and temperatures are high.
To avoid dehydration, cactusses have developed wide palmated or cilindirical stems and reduced or vestigial leaves.
They use stem tissues to store water. Vestigial or reduced leaves to avoid transpiration and water loss.As their leaves are not developed, their stems photosynthetize to produce organic compounds.
Some species are very rich in water and nutrients, so they turn to be covetted by other species. Animals living in the same environment look for them as a source of food.
To avoid predation, cactusses have developed large and numeros spines that are leaves modifications. This is another adaptation to avoid being eaten by animals and avoid loosing water through leaves.

Why is the water cycle important for ecosystems?(1 point) The water cycle helps recycle and transport carbon around the planet. The cycle replenishes the carbon supply of ecosystems. The water cycle uses photosynthesis to make clouds. These clouds make surface water that animals drink to survive in their ecosystem. The water cycle permanently removes water from underground and large bodies of water and transports it to terrestrial ecosystems that need water. The water cycle helps recycle and transport water around the planet. The cycle replenishes the water supply of ecosystems
Answer: The water cycle helps recycle and transport water around the planet. The cycle replenishes the water supply of ecosystems
Explanation:
The water cycle simply refers to how water continuously move within the Earth. It is also called the hydrological circle. Water cycle depicts many processes such as how water evaorates into vapor, how clouds are formed through condensation and then sent back to the Earth as either rain or snow.
Based on the options given, the water cycle helps recycle and transport water around the planet. The cycle replenishes the water supply of ecosystems.

The flooding of fields in winter can affect aquifers without having long term impacts on the height of the water table. Which statements explain why this is possible?
Select the TWO correct answers.
A. In winter, using groundwater to flood fields causes the water table to drop because water is withdrawn from the aquifer.
B. In winter, removing water from the aquifer causes the water table to rise because water covers the areas where rice is grown.
In spring, changes in the level of the river cause the water table to rise because water flows from the river into the aquifer.
C. In spring, removing water from the aquifer causes the water table to drop because water flows from the aquifer to the river.
D. In summer, changes in the level of the river cause the water table to rise because water flows from the river to the aquifer.
The flooding of fields in winter has no long-term effect on the height of the water table because removing water from the underground water - the aquifer causes water to drop and summer melts water into the water table.
Aquifers, Water Tables, Summer, and WinterDuring winter, the flooding of the field traps water from going back into the aquifers and the use of water from them causes the water level to drop.
Due to the melting of snow in summer, the water levels are normalized. Therefore, the correct answers are C and D.

1. How do radiation, conduction, and convection affect the atmosphere?
2. How does greenhouse effect warm the earth?
Answer:
1. radiation, conduction and convention all play a roll in moving heat between earth's surface and atmosphere because since air is a poor conductor, most energy transfers by conduction occuring right near the earth's surface. Conduction directly affects air temperature only a few centimeters into the atmosphere. convection works to heat the troposphere. Durring the day, the sun's radiation heats the earth's surface. the land becomes warmer than the air. Air near the Earth's surface is essentially warmed by both radiation and conduction.
