Why do scientists make a hypothesis before an experiment
Answer:
Scientists make a hypothesis before an experiment so the can make an educated guess of the outcome before they get one.
Explanation:
The hypothesis is important because it allows scientists to make predictions about the upcomming experiment and then analyze the data after the experiment.
If you wanted to study large, migratory grazing animals like wildebeest, which biome would you chose to visit?
Answer: Savanna
Explanation:
The Savanna is a biome located in Africa and characterized by a lot of grass and dispersed trees. The climatic conditions are warm all year round and the summers are wet.
The presence of so much vegetation makes it an ideal biome for large herbivores like elephants, giraffes and wildebeests. As a result of so many herbivores being there, there are lots of carnivores as well such as lions and cheetahs.
╭☞ If you wanted to study large, migratory grazing animals like wildebeest, which biome would you chose to visit?
ANSWER:╭☞ Savanna or Savannah
Explanation:
╭☞ Because Savanna or savannah, is a migratory grazing animals like wildebeest and type of plant that grows under hot, seasonal climatic conditions and is characterized by an open tree trunk (i.e., scattered trees) above a continuous- continuous tall grass understory (the layer of vegetation between the canopy of the forest and the ground).

Answer:
100% of children will have a double heterozygous genotype (EeWw)
Explanation:
A homo-zygous individual is an individual that has two dominant alleles or two recessive alleles for a given gene/locus. A dihybrid cross, also known as Mendelian dihybrid cross, refers to a type of cross in which both parents differ in two observed phenotypic traits which are controlled by two distinct non-linked genes. When both parents are inversely homo-zygous for both genes as in this case (i.e., one parent is homo-zygous dominant for the first gene and homo-zygous recessive for the second gene, while the other parent is homo-zygous recessive for the first gene and homo-zygous dominant for the other), all the F1 will be heterozygous, i.e., all F1 individuals will have the EeWw genotype because each parent can produce only one type of gamete (either Ew or eW). If both genes are subject to complete dominance, then the expected phenotypic ratio of the F2 obtained by crossing double heterozygous individuals will be 9:3:3:1, i.e., 9/16 individuals will have the dominant phenotype for both traits (in this case E_W_ genotype), 3/16 individuals will have the dominant phenotype for the first trait (in this case, dominant earlobe E_ww genotype), 3/16 individuals will have the dominant phenotype for the second trait (in this case, dominant hairline eeW_ genotype), and 1/16 will have the recessive phenotype for both traits (in this case, double recessive eeww genotype).
Darwin presented a hypothesis about how evolution takes place. Now this hypothesis has become a theory. What caused the idea to become a theory? A. Darwin shared his ideas with others, and many scientists have performed experiments that support this idea. B. Darwin is well respected, and scientists honor his work by referring to his idea as a theory. C. Darwin performed an experiment that supported his hypothesis. D. Darwin convinced everyone around him that it was a good idea.
Answer:
C. Darwin performed an experiment that supported his hypothesis.
Explanation:
Darwin believed that his experiment, which was comparing the finch's beaks from Galapagos Archipelago, in which there was variation between the size and shape of beaks, as the basis in which he believed evolution was correct. However, variation does not mean evolution, and evolution, in which it calls for a chain of events to create beneficial traits successively, is nigh impossible to occur in the real world. Again, that is not to say that there is no such thing as variation, in which there is, in which people or animal groups adapt to their natural habitat. However, to state that adaptation is proof that a species becomes another is to go out on a limb, and current failures of "new species" (in that it originates from today's day and age, rather then discovered) to emerge is proof of such.

Every day we make choices that can potentially affect our environment. For example, we may toss a plastic drink bottle into the nearby trash because it’s more convenient than walking all the way to the recycling bin. Think about three choices you made this week that could have affected the environment. Did your choices have a positive or a negative effect on the environment? Explain your reasoning.
The three choices that could have affected the environment are as follows:
Utilization of plastic to make it easy for carrying objects.Plants trees in order to build a green environment. Overdependency on vehicles rather bicycles and pedestrians. What is Environment?The environment may be defined as anything which is present in the surroundings of living organisms. This environment basically has two types of factors biotic and abiotic factors.
In the above three choices, building a green environment has a positive effect on the environment. It may also affect living organisms positively. While the rest of the two may stimulate a negative impact on the environment by increasing the levels of carbon dioxide by liberating emission and non-biodegradable plastics.
Therefore, the three choices that could have affected the environment are well mentioned above.

Imagine a continuation of the experiment described above. How might NS3/4A expression impact Sendai virus replication, as measured by the amount of virus produced by the different cells? a. Cells expressing NS3/4A will produce more Sendai virus than cells that do not express NS3/4A. b. Cells expressing NS3/4A will produce less Sendai virus than cells that do not express NS3/4A. c. The two types of cells will produce roughly equal amounts of Sendai virus.
Answer:
The correct answer is - a. Cells expressing more NS3/4a will produce more Sendai virus than cells that do not express NS3/4a.
Explanation:
NS3/4a is a multiprotein serine protease that is a non-covalent heterodimer consisting of a catalytic subunit protein. This heterodimer has an N-terminal one-third of NS3 protein and at an activating cofactor (NS4A) protein.
It acts as an antagonist for cytokine promoters. Thus in the absence of cytokines or reduced levels of cytokines due to inactive promoters) the expression of the virus would increase.

Answer:
uses light as its energy source and carbon for organic compounds.
Explanation:
The purple non-sulfur bacteria which depends on light produces organic food just like plants through the process of photosynthesis. The purple non-sulfur bacteria uses carbondioxide and water with sunlight produces oxygen and glucose which is an organic compound. So that's why purple non-sulfur bacteria is also known as phototrophic means organism that produces their own food through photosynthesis.

Which phase of the cell cycle is the least common process of mitosis and what could be the reason?
Answer:
In anaphase, the shortest stage of mitosis, the sister chromatids break apart, and the chromosomes begin moving to opposite ends of the cell. By the end of anaphase, the 2 halves of the cell have an equivalent collection of chromosomes. In telophase, 2 daughter nuclei form. The nuclear envelope beings to reappear.
What happens when a cycle res turns to its starting point
Explanation:
Now that we’ve learned how autotrophs like plants convert sunlight to sugars, let’s take a look at how all eukaryotes—which includes humans!—make use of those sugars.
In the process of photosynthesis, plants and other photosynthetic producers create glucose, which stores energy in its chemical bonds. Then, both plants and consumers, such as animals, undergo a series of metabolic pathways—collectively called cellular respiration. Cellular respiration extracts the energy from the bonds in glucose and converts it into a form that all living things can use.

Risk assessment is often used to set “acceptable” levels of toxins for the environment. Propose a concern people may have about using risk assessment in this way.
The concern about risk assessment of acceptable levels of toxins can be a failure to use appropriate risk metrics, incorrect measuring of known risk, failure to take known risks into concern, or failure in risk communication or risk monitoring.
What is meant by risk assessment?A risk assessment is a step-by-step process that, in combination with an exposure analysis and other elements, provides an estimate of the likelihood that an adverse health event will occur as a result of ingestion, inhalation, or absorption of one or more toxins. One of the most important aspects of risk assessment is toxicity assessment.
A toxicity assessment is a study of a substance’s ability to cause harm – and how much harm it can cause. It’s important to note that not all substances are toxic – many therapeutic medications are acute toxic but beneficial when taken at the right dose.

a que distancia se encuentra una gaviota respecto del nivel del mar?
Answer:
Para determinar la distancia a la que se encuentra una gaviota respecto del nivel del mar, es necesario medir la altura a la que se encuentra volando. Así, dado que el nivel del mar tiene una altura considerada como de 0 metros, si la gaviota está volando a unos 500 metros de altura, por ejemplo, esa será su distancia respecto del nivel del mar.
