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.

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.

g With respect to their 3' and 5' ends, the two polynucleotide chains of a double-stranded DNA molecule are:
Answer:
They are antiparallel
Explanation:
They are antiparallel because one strand of 3' faces the end of 5' of another strand and 5' end of one strand faces 3' end of another strand. Which indicate that 5 phosphate group faces the end of 3 hydroxyl group and they are of opposite directions to each other because it has opposite polarity with each other .
What could a weather forecast on Mars be?
Answer:
Cold
Explanation
Weather conditions on Mars
Mars is an extremely cold planet with an average temperature around minus-80 degrees. Temperatures can dip to minus-225 degrees around the poles. Periods of warmth are brief — highs can reach 70 degrees for a brief time around Noon at the equator in the summer.
What does this process lead to?
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 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.

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.

A.
The trait for spore color is determined by exactly one gene.
B.
The trait for spore color is determined by more than one gene.
C.
The allele for black spores is dominant over that for white spores.
D.
The allele for white spores is dominant over that for black spores.
Answer:
C.
Explanation:
Since there are more of an outcome of black spores it would make sense that this trait is dominant.
White spores seem to be recessive in this case too.
I also suspect the parents are both heterozygous. They both carry one trait for black and one for white.
Hopefully this is correct. Have a great day.

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.
