How is the word theory used in science?
A. Scientists use the word theory when they mean that they have a hunch or a guess.
B. Scientists never use the word theory when it applies to a tested, highly reliable scientific explanation of events in the natural world.
C. Scientists use the word theory when a hypothesis is well supported and it unifies a broad range of observations.
D. Scientists use the word theory when they are not certain about an idea.
E. Scientists use the word theory only in biology and not in other sciences.
Answer:
the correct answer is C you welcome
Option C is correct. Scientists use the word theory when a hypothesis is well supported and it unifies a broad range of observations.
A theory can be described simply as a series of ideas or guess that was tabled to explain a concept.
These ideas and concepts are well thought out by scientists to explain a phenomenon and their explanations are based on how they generally view the world. When these ideas which we can also call hypotheses, are well supported based on similar and diverse observations from scientists, we can term them as THEORY.
Hence we can conclude that scientists use the word theory when a hypothesis is well supported and it unifies a broad range of observations.

Which of the following base pairs would be found in a cell
The base pair cytosine and guanine is found in the cell. The correct option is D.
What are base pairs?A base pair is a primary component of double-stranded nucleic acids that comprises two nucleobases that are hydrogen-bonded to one another.
They are the foundations of the DNA double helix and make a contribution to both DNA and RNA's folded structure.
Purines and pyrimidines are nitrogen bases that form hydrogen bonds between DNA strands.
Predicated by Chargaff's Rule, they associate together via complementary pairing A::T and G::C. The purines in DNA are the same as those in RNA: adenine and guanine.
The 2 significant pyrimidine bases in DNA are cytosine and thymine, which base pair with guanine and adenine. Uracil supplants thymine and base pairs to adenine in RNA.
Thus, the correct option is D.

In the upper layers you find fossils of rodents, but in layers further below you find amphibians but no rodents. In some still-deeper layers there are neither amphibians nor rodents but there are fossils of beetles and other insects. In the deepest layers you find no insects but you do find millipedes. This fossil evidence suggests that
Answer:
millipedes were the first of these animal groups to evolve.
Explanation:
Fossils are structural remains of animals from the past. As these animals die, it takes years for the remains to be buried.
The millipedes are at the lower layer of the rock, next to insects, amphibians, and then rodents. This shows that millipedes existed and evolved before the rest of the found animal fossils.

Farmers have selected for increased oil content from corn. For a long time, the plants responded with steadily increasing oil content, but recently the response slowed and then stopped. When this line of corn is crossed to another line and the hybrids are selected, the oil content resumed its climb. What is a plausible reason for the lack of response?
A. The environmental conditions improved.
B. The genetic variation for the trait was exhausted.
C. There was too much genetic variation for the trait.
D. The environmental conditions deteriorated.
E. Artificial selection is different than natural selection.
Answer:
B. The genetic variation for the trait was exhausted.
Explanation:
Oil content is a quantitative trait, ie., a phenotypic feature that depends on the accumulative effects of many genes and the interaction of a genotype with its environment. During crop improvement, the plants (i.e., lines) containing desired alleles involved in the variation of this trait will be selected, thereby increasing oil content but simultaneously decreasing the genetic variation of the population. In consequence, after successive rounds of artificial selection, lines will not have sufficient genetic diversity to be again selected for this trait.

2. Think about an animal like a rhinoceros, a deer, or an antelope. What parts of their body other than their hair must be composed of quite similar material to your nails and hair
Answer:
horns and hooves
Explanation:
horns and hooves are made of kerotin, just like nails and hair.
Keratin is the protein that composes the external layers of the epidermis. It can be found in elements like feathers, nails, and hair. Other parts of the body that might be composed of keratin are horns and hooves.
-------------------------------------
Keratin is a fibrous protein that can be found in epithelial cells that cover internal and external surfaces.
Keratin is the main component of horns, hooves, feathers, hair, and nails.
Horns are hollow and pointed structures that emerge from the skull of the animal.
Animals get born hornless. As they grow they develop these structures. Most of them complete the development near the reproductive stage of the animal.
At sexual maturity age, competitive interaction increases, and animals use them to defend themselves and hurt the opponent. Males of some species also use them to attract females.
Hooves are very developed nails that cover the ugunaltes' fingers. These animals only use the extreme of the fingers to walk.
Like all nails, hooves grow continuously and wears out as the animal walks or runs.

A: a process of energy conversion that releases energy from food in the presence of oxygen, forming new compounds
B: a process of energy conversion that captures light energy and transforms it into chemical energy
C: a process of energy transfer that converts liquid water into water vapor
Answer:
I would say a process of energy conversion that releases energy from food in the presence of oxygen, forming new compounds.
Explanation:
Why? Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds
Answer:
A.) A process of energy conversion that releases energy from food in the presence of oxygen, forming new compounds.
Explanation:
Photosynthesis in plants converts solar energy into chemical energy using electrons and protons from water. The process of photosynthesis in plants involves a series of steps and reactions that use solar energy, water, and carbon dioxide to produce organic compounds and oxygen.
8) Outline what you would need to know to answer the following question: of all the proteins that exist on earth at this time, what fraction of them have a known structure
Answer:
To solve this question, it is necessary to consider the number of protein structures that have been empirically verified and the number of Open reading frames predicted from sequencing data
Explanation:
The most common methodologies used to determine protein 3D structure are nuclear magnetic resonance (NMR) and X-ray crystallography. Although both methods are efficient, the determination of 3D protein structures in physiological conditions is a time and cost-consuming task. Moreover, due to recent advances in bioinformatics and sequencing methodologies, the amount of protein Open Reading Frames predicted from sequencing data (especially obtained from Next Sequencing Generation studies) is many times higher. Indeed, less than 5% of sequenced proteins have an empirically validated 3D structure.
Many of the plants in a grassland environment are specifically adapted to that habitat. The natural selection that led to this adaptation was a result of all
the following EXCEPT
populations of plants naturally exhibit variation
plants produce more offspring than can survive.
the available resources do not support all the plants,
related plant species share some genetic material.
Answer: hybridisation between related species is unlikely to contribute to adaptive speciation.
Explanation: any population has natural genetic variation. The available resources are insufficient for all plants (and conversely, not all offspring survive). Natural selection favours variations better suited to the conditions.
Although hybridisation is more common in plants than animals, and can lead to speciation, adaptive radiation from an ancestral species is the general response to environmental change, such as from rainforest to savanna. There is low probability of selective advantage from hybridisation of two ancestral species adapted to niches within the original habitat when the conditions in those niches changes significantly.
Answer:
The correct will be C: The available resources do not support all the plants.
