Explanation:
This substitution score matrix called _____ is derived from protein families that are characterized by blocks of conserved amino acid sequences.
Answer:
BLOSUM
Explanation:
A substitution matrix is a matrix used in bioinformatics (and also in computational biology) to determine/estimate the rate at which one character -which is specified by a nucleotide sequence in nucleic acid alignments or by one amino acid in protein alignments-, changed to another character during the course of the evolution. The BLOcks SUbstitution Matrix (popularly known as BLOSUM) is a substitution matrix used to score one amino acid for another in a protein alignment. The BLOSUM substitution matrix is particularly useful to compare evolutionarily conserved regions between protein sequences and thus score their alignments, where each entry is indicated by a similarity score between two amino acids.
how are the processes of photos sentences and saw your respiration opposites of one another
Answer:
This question is not well structured. Based on understanding, the correct structure should be: How are the processes of photosynthesis and respiration opposites of one another?
They are opposite because photosynthesis uses the products of cellular respiration and vice versa.
Explanation:
Photosynthesis and cellular respiration are both metabolic processes that occurs within the cells of living organisms. Photosynthesis is the process where green plants synthesize food (sugar) in the presence of sunlight using carbon dioxide (CO2) and water (H2O). The general equation is as follows:
6CO2 + 6H2O → C6H12O6 + 6O2
On the other hand, respiration is the process whereby cells of living organisms synthesize usable energy (ATP) for use by breaking down glucose (C6H12O6) in the presence of oxygen. The equation is as follows:
C6H12O6 + 6O2 → 6CO2 + 6H2O
Based on the observation of the reactants and products of each process, it can be realized that the PRODUCTS of one process is the REACTANTS of the other. In other words, photosynthesis makes use of CO2 and water as REACTANTS, which are the PRODUCTS of respiration while cellular respiration uses glucose and oxygen as REACTANTS, which are PRODUCTS of photosynthesis.

Is there a scientific discovery in today’s world that has been overshadowed by popular belief? Explain. What role do you think popular belief has on scientific discoveries?
The history of science is also a history of people resisting new discoveries that conflict with conventional wisdom.
When Galileo promoted Copernicus’ theory that the Earth revolves around the sun – counter to church doctrine about the Earth being the center of the universe – he wound up condemned by the Roman Inquisition in 1633. Charles Darwin’s theory of evolution – that new species develop as a result of natural selection on inherited traits – ran into opposition because it contradicted long-held scientific, political and religious beliefs. Alfred Wegener’s 1912 proposal that Earth’s continents move relative to each other – the theory of continental drift – was rejected for decades, in part because scientists held fast to the traditional theories they’d spent careers developing.
These kinds of examples aren’t only historical, unfortunately. We’re used to hearing about how the general public can be dense about science. You might expect some portion of everyday folks to take their time coming around on truly groundbreaking ideas that run counter to what they’ve always thought.
But scientists, too, hold their own personal beliefs – by definition, based on old ways of thinking – that may be holding back the innovation that’s at the heart of science. And that’s a problem. It’s one thing for an average Joe to resist evolving scientific theories. It’s quite another if a scientist’s preconceived notions holds us back from discovering the new and unknown – whether that’s a cure for Zika or a cutting-edge technology to combat climate change.
Personal beliefs as publication roadblocks
Real scientific progress occurs when laboratory or field research is reported to the public. With luck, the finding is accepted and put into practice, cures are developed, social policies are instituted, educational practices are improved and so on.
This usually occurs though publication of the research in scientific journals. There’s an important step between the lab and publication that laypeople may not know about – the evaluation of the research by other scientists. These other scientists are peers of the researcher, typically working in a closely related area. This middle step is commonly referred to as peer review.
In a perfect world, peer review is supposed to determine if the study is solid, based on the quality of the research. It’s meant to be an unbiased evaluation of whether the findings should be reported via journal publication. This important step prevents sloppy research from reaching the public.
However, in the real world, scientists are human beings and are often biased. They let their own beliefs influence their peer reviews. For example, numerous reports indicate that scientists rate research more favorably if the findings agree with their prior beliefs. Worst of all, these prior beliefs often have nothing to do with science but are simply the scientists’ personal views.
‘But that’s counter to what I thought…’
How is this a problem for scientific innovation? Let’s look at how some personal beliefs could prevent innovative science from reaching the public.
Minorities aren’t good at STEM.” The stereotype that “women are not good at math” is commonly held – and also happens to be incorrect. If a scientist holds this personal belief, then he is likely to judge any research done by women in STEM (Science, Technology, Engineering and Mathematics) more negatively – not because of its quality, but because of his own personal belief.
For instance, some studies have shown that female STEM applicants in academia are judged more harshly than their male counterparts. Because of this gender bias, it may take a female STEM researcher more time and effort before her work reaches the public.
Some racial minorities face similar kinds of bias. For example, one study found that black applicants are less likely to receive research funding from the U.S. National Institutes of Health than equivalently qualified whites. That’s a major roadblock to these researchers advancing their work.
However, people often believe that comic books are just low-brow entertainment for kids. If a scientist holds this personal belief, then she’s likely to judge any psychology research using comic books more negatively. Because of this, scientists like me who focus on comic books may not be able to publish in the most popular psychology journals. As a result, fewer people will ever see this research.
The history of psychology supplies one example. Behaviorism was psychology’s dominant school of thought for the first part of the 20th century, relying on observed behavior to provide insights. Its devotees rejected new techniques for studying psychology. During behaviorism’s reign, any talk of internal processes of the mind was considered taboo. One of the pioneers of the subsequent cognitive revolution, George A. Miller, said “using ‘cognitive’ was an act of defiance.” Luckily for us, he was defiant and published one of the most highly cited papers in psychology.
The scientific endeavor requires belief. There would be no science if people didn't have faith in the objectivity of other scientists' work.
What is the importance of scientific discoveries?New techniques, new galaxies, new planets, and potentially even the existence of life on them are just a few of the previously unthinkable possibilities that science has made feasible. Further possibility lies in the future.
Scientism is a very odd word, but for reasons we will see, it is an important one. Despite being a relatively new term, it is connected to numerous other “isms” that have a long and violent history.
The moral standing of professors and mentors, the order and understanding of nature, and the compatibility of reason and truth.
Therefore, scientific discovery in today’s world that has been overshadowed by popular belief.

Movement of individuals into or out of the population, called gene flow, impacts evolution of populations because:_________.
a. it can lead to extinction of one or more populations.
b. it may cause genetic drift.
c. it leads to a redistribution of alleles
d. adaptive radiation results.
e. a founder effect will occur.
Answer:
c. it leads to a redistribution of alleles
Explanation:
The gene flow can be defined as the movement of genetic material from one population to another within the same species. This movement may be associated 1-with the migration of individuals and subsequent reproduction of these organisms in the new population or 2-with the movement of gametes (eg., pollen dispersal) among populations. In both cases, gene flow is known to alter the frequency of particular alleles between populations and consequently also modify the evolutionary patterns of these populations.
Gene flow is the migration of genes or alleles and refers to the transfer of the genetic material. If the rate of the gene flow is high then two populations will say to be an effective population.
It just leads to redistribution of the genes or alleles with the in the popualtion of species. Hence the option C is correct.Learn more about the individuals into or out of the population, called gene flow.

Chiasma
Answer: Chiasmata are specialized chromatin structures that link homologous chromosomes together until anaphase I (Figs. 45.1 and 45.10). They form at sites where programmed DNA breaks generated by Spo11 undergo the full recombination pathway to generate crossovers. At a given chiasma, an exchange of genetic material can occur between both chromatids, what is called a chromosomal crossover, but this is much more frequent during meiosis than mitosis. In meiosis, absence of a chiasma generally results in improper chromosomal segregation and aneuploidy.

how energy is recycled in an ecosystem. how our atmosphere maintains its temperature. the importance of decomposers in an ecosystem. the one-way flow of energy in an ecosystem.
Answer:
The flow of energy in ecosystems is unidirectional or one-way.
Explanation:
Energy is the ability to do work. Energy flows in one direction in an ecosystem and is not recycled. This is because during the transfer of energy from one level to another, energy is lost. Most of the energy received from the sun by producers, plants, is lost as heat to the surroundings. The rest energy is converted by plants to produce food in the form of chemical energy.
Primary consumers feed on plants and secondary consumers feed on the primary consumers and so on up to quaternary consumers. However, at each level of energy transfer, some energy is lost as heat during respiration, some as unused or undigested materials, while some others are used for each organisms metabolic activities. About 90% of energy in a trophic is used at that trophic level. Therefore, only about 10% as much energy is available to organisms at each successive trophic level. Therefore, energy is not recycled in ecosystems.
Earth's atmosphere maintains its temperature by means of the earth's energy balance. This refers to how incoming from the sun and outgoing energy from the earth are in balance, thereby keeping earth's temperature constant.
Decomposers, are organisms such as bacteria, fungi, and small animals such as ants and worms that eat and decompose dead and waste organic matter and which recycle nutrients back into food chains making them available for plants use. Therefore, decomposers are an essential components of all ecosystems.

Which two changes would increase the density of ocean water?
A. Increasing the amount of light that enters it
B. Decreasing its salinity
C. Increasing the amount of water that evaporates from it
I D. Decreasing its temperature
Answer:
The answer is simply D.
Explanation:
One factor that does affect density is the temperature. In general, most substances become less dense as temperature increases and more dense as temperature decreases.
The amount of water that evaporates from the ocean and the temperature are the two factors that influence its density. So options C and D are both true for this statement.
What is the effect of temperature on density?
The ocean water has more salts and minerals dissolved in it, so it is denser than normal fresh water. Some factors further decrease or increase the density of the ocean water. When the temperature drops, the water cools and ice forms. The ice is denser than the water, so it will sit below it.
As the temperature rises, the water evaporates, increasing salinity because more salts are present in the ocean water than in the water itself. The concentration of salt in the ocean determines the salinity of the ocean, and it can increase the density of ocean water when the concentration of salt is higher.
Hence, the amount of water that evaporates from the ocean and the temperature are the two factors that influence its density. So options c and d are both true for this statement.
