Answer: The answer is A cell theory.
Explanation: For our cells to be as developed and complex as they are today a huge evolutional process was necessary. This process is explained in the cell theory
DNA and molecular evidences are the additional evidences to support Darwin's theory. The correct option is B.
What is Darwin's theory?According to Darwin's theory, all species of organisms emerge and develop through natural selection of slight, inherited variations that significantly raise the individual's capacity to compete, stay alive, and reproduce.
It is backed up by research from a wide range of scientific disciplines, as well as genetics, which shows that DNA from different species is similar.
Fossils, embryological studies, anatomical and morphological characteristics, and molecular biology are examples of evidence that support the theory of evolution by comparing DNA sequences.
Thus, the correct option is B.

If the number of photosynthetic organisms on Earth decreased drastically, which would happen as a result? Less water would be available on Earth’s surface. Less solar energy would reach Earth’s atmosphere. More oxygen gas would be found in Earth’s atmosphere. More carbon dioxide gas would be found in Earth’s atmosphere.
If photosynthetic organisms are decreasing on Earth there is no consumption of carbon dioxide, hence option 4 is correct.
How much carbon dioxide Earth’s atmosphere?The amount of oxygen in the atmosphere will likewise decrease as the number of photosynthetic species rises.
More carbon dioxide gas would be found in the atmosphere because forests, especially rainforests, create more oxygen. The development of oxygenic photosynthesis was the most significant metabolic advancement in Earth's history.
It liberated life from the finite supply of reductants drawn from geochemistry and allowed it to create energy and reduce power directly from sunshine and water.
Therefore a decrease in photosynthetic organisms increases the carbon dioxide gas in Earth’s atmosphere.

Answer:
it acts as products/reactants it acts to stablize the temperature
Explanation:
Dry heat sterilization is very useful to be used in materials that cannot come into contact with forms of heat sterilization such as steam. It is also widely used for objects that cannot come into contact with very high temperatures.
This type of sterilization is done by buckling, incineration, intra-red rays or hot air oven. In any case, it is important that the water is completely removed, both from the object and from the sterilization vehicle. This is because water is easily used by possible microorganisms to stabilize the temperature in their bodies, which can cause sterilization failures.

Read the passage from Darwin's journal. These two species of Amblyrhynchus agree, as I have already stated, in their general structure, and in many of their habits. Neither have that rapid movement so characteristic of the genera Lacerta and Iguana. They are both herbivorous; although, the kind of vegetation on which they feed is so very different. Mr. Bell has given the name to the genus from the shortness of the snout; indeed, the form of the mouth may almost be compared to that of the tortoise: one is led to suppose that this is an adaptation to their herbivorous appetites. It is very interesting thus to find a well-characterized genus, having its marine and terrestrial species, belonging to so confined a portion of the world. The aquatic species is by far the most remarkable because it is the only existing lizard which lives on marine vegetable productions. As I at first observed, these islands are not so remarkable for the number of the species of reptiles; as for that of the individuals, when we remember the well-beaten paths made by the thousands of huge tortoises—the many turtles—the great warrens of the terrestrial Amblyrhynchus—and the groups of the marine species basking on the coast-rocks of every island—we must admit that there is no other quarter of the world where this order replaces the herbivorous mammalia in so extraordinary a manner. What differences did Darwin find about the two species? One is fast, while the other is slow. One eats plants, while the other eats meat. One lives inland, while the other lives in the water. One has a long snout, while the other has a short snout.
Answer:
One lives inland, while the other lives in the water.
Explanation:
Amblyrhynchus cristatus is a marine reptile that lives in the Galápagos Islands. This species attracted the attention of Darwin because it is a marine iguana that lives exclusively in the Galapagos and, interestingly, their close relatives inhabit in land, also in the Galápagos Islands. The marine and land iguanas from Galápagos form a phylogenetic clade that is characterized by high diversification levels, which are evidenced by conspicuous phenotypic differences. These species can hybridize with each other, but the offspring are infertile. Recently, it has been shown by using phylogeographic analysis that both species diverged 8-10 million years ago.
Answer:
They both eat plants.
Explanation:
They are both herbivorous; although, the kind of vegetation on which they feed is so very different.
The chemical equation below summarizes the process of photosynthesis.
(604 (1) 0 + 111e13) và (O2 + CK Og
Where is the energy shown in the equation transferred as a result of photosynthesis?
into water
into the air
into sugars
into the ground
Answer:
The chemical equation of Photosynthesis in the question is not clear but the energy goes into water.
The answer is "Into Water"
Explanation:
Photosynthesis is a metabolic reaction which involves the synthesis of sugars (Glucose) in plants using carbondioxide and water input in the presence of sunlight. Photosynthesis, which occurs in the Chloroplast of plant cells, occurs in two stages viz: light dependent stage and light-independent stage.
The light dependent stage involves the production of ATP and NADPH molecules, which will be used in the light-independent stage. The chemical equation of photosynthesis is as follows:
6CO2 + 6H2O ---light energy--> C6H12O6 + 6O2
The light energy input in this reaction (from sunlight) is used in the light-dependent stage to break down water molecules, a process called PHOTOLYSIS OF WATER. The photolysis of water releases electrons and protons used to build a proton pump for the synthesis of ATP.
Therefore, the energy input from photosynthetic process goes into water.

What does Saccharomyces cerevisiae (Baker’s yeast) need to survive?
Answer:
Food (Sugars)
Explanation:
S. cerevisiae feeds on sugars for energy, in the process producing carbon dioxide and alcohol (this is fermentation in a nutshell). The carbon dioxide bubbles get trapped in the dough, creating the lift that makes the dough rise. The alcohol, meanwhile, evaporates when baking, transforming into gas that also contributes to the rise of the bread. The alcohol, along with acids produced during the fermentation process, impart that wonderful flavor and aroma associated with yeast-leavened breads.
Binary fission occurs in which of the following type of organsim?
Answer:
A. Prokaryotes like bacteria
Explanation:
Binary fission is a type of asexual reproduction (requiring only one organism, as opposed to sexual reproduction, which requires two) occurs when an organism itself splits into two - hence binary (bi- means two).
Binary fission occurs most often in prokaryotes; eukaryotes like plants and animals engage more in sexual reproduction because they are more complex.
The answer is thus A.

In an electron microscope, the sample is bombarded with a stream of electrons that are expelled from an electron gun. The electrons interact with the sample component, the result of which is transformed into an image. Why do you think electron microscopes allow for greater magnification than compound microscopes?
Answer:
It is because the electron microscope uses a shorter wavelength electron
Explanation:
In an electron microscope the sample is always bombarded with a stream of electrons. These electrons usually have shorter wavelengths.
The electrons interact with the sample component well, the result of which is transformed into an image which is always clearer and allows for greater magnification than the compound microscope as a result of the short wavelength electrons being used.
Answer:
Due to the shortened wavelength electron it causes a greater magnification than compund microscopes.

Scientists often ask questions to clarify data or guide scientific research. What are two scientific questions you have that
could clarify relationships about the DNA or traits of these orchids?
Answer:What traits would orchids have if the MADS-box genes were not duplicated?
If the genetic mutation changed the shape of the flowers, would pollinators still be attracted to the orchids?
Explanation: The example given by Plato
If the genetic mutation changed the shape of the flowers, would pollinators still be attracted to the orchids.
What is Genetic mutations?The DNA sequence of a gene is altered to generate a different result, which is known as a genetic mutation. The DNA sequence of that gene is permanently altered.
For humans to develop, which is the process of change over a number of generations, genetic variances are crucial. In one person, a spontaneous genetic mutation takes place.
The genetic mutation of that person is passed down through generations (hereditary) to their offspring. If the mutation increases a person's likelihood of survival or immunity to disease, it starts to be handed down through generations and disseminated throughout the community.
Therefore, If the genetic mutation changed the shape of the flowers, would pollinators still be attracted to the orchids.

Which of the following is an example of reproductive isolation? two populations of finches that cannot produce viable offspring two populations of finches that have different feather colors two populations of salamanders that live in different lakes two populations of salamanders that have different tail lengths
The correct answer is A. Two populations of finches that cannot produce viable offspring
Explanation:
Reproductive isolation is a biological and evolutionary phenomenon that prevents two species from successfully reproducing, this means they cannot produce offspring or the offspring is not fertile, even if these species had a common ancestor. Additionally, as a result of reproductive isolation, each species keeps its genes and features. This phenomenon is best exemplified in "Two populations of finches that cannot produce viable offspring " because this refer to the barriers for different species to reproduce or produce viable offspring, which is the focus of reproductive isolation.
