Which field of earth science seeks to understand why Jupiter's moon has so many active volcanoes?
Answer:
Explanation:
Jupiter's fifth moon, Io, is the most volcanically active body in the solar system. Plumes of sulfur spew upward as high as 190 miles. The surface of Io is splotched with lava lakes and floodplains of liquid rock.
Astronomers have mapped about 150 volcanoes on the moon, some of which blast lava 250 miles (400 km) out into space. There are volcanoes all over Io's surface, and as scientists perform observations they still occasionally see new hotspots pop up. For example, NASA's Juno spacecraft, which is currently orbiting Jupiter, found a possible new hotspot on Io on Dec. 16, 2017.(k r

Answer:
Which phase of mitosis is characterized by each pair of sister chromatids moving to opposite sides of the cells?
A) Metaphase
B) Anaphase
C) Prophase
D) Telophase
The answer is D) Telophase
Telophase is described as the phase of mitosis is characterized by each pair
of sister chromatids moving to opposite sides of the cell.
Telophase is the final stage of mitosis and it involves the movement of the
chromatids to opposite sides of the cell till two sets of nuclei are formed.
Telophase is the last phase before the process of cytokinesis which is the
division of the cytoplasm into two parts starts to take effect.

Transcribe DNA Nucleotide Allele Nucleus Traits Amino acid
Nucleic acid Protein Cytoplasm Ribosome RNA Gene Chromosome
Mutation Non-coding DNA RNA Polymerase Genome"
Answer:
The deoxyribonucleic acid (DNA) is the hereditary material in all living things. In eukaryotic organisms, this molecule (DNA) is found within a nucleus, while in prokaryotic organisms DNA is localized in the cytoplasm, in a region named nucleoid (prokaryotic cells lack a membrane-bound nucleus). The DNA consists of two polynucleotide chains coiled around each other in order to form a double helix. The genes are made up of DNA, and they represent the basic units of heredity. In the first place, genes are transcribed into RNA molecules by an RNA polymerase (RNA pol), and, subsequently, this RNA molecule (generally mRNA) moves to the cytoplasm to be translated into proteins in ribosomes. An allele is a variant of the same gene that exhibits differences in the nucleotide sequence (i.e., mutations). The different alleles may encode different but related variants of the same protein, since these differences may encode different amino acids, thereby leading to phenotypic differences in the same trait that are heritable. A genome represents the complete set of the genetic material of an organism. The genome is the collection of all set of genes and its non-coding DNA (i.e., nucleotide sequences that don't encode proteins). In eukaryotes, the genome is represented by one or more nuclear chromosomes and the mitochondrial genome, while in procaryotes the genome is represented by a single chromosome (i.e., a circular DNA molecule).
Select the statement that describes recruitment in muscle contraction. Neurotransmitters from the synaptic terminal of a motor neuron stimulate an action potential in the muscle fiber. The contraction of muscle fibers in one muscle stimulates the contraction of antagonistic muscles in an opposing muscle group. More motor neurons and larger motor units are activated to stimulate a greater number of muscle fibers for a more powerful muscle contraction. A decreasing number of motor neurons are connected to the muscle fiber as a muscle grows and becomes stronger.
Answer:
The correct answer is - More motor neurons and larger motor units are activated to stimulate a greater number of muscle fibers for a more powerful muscle contraction.
Explanation:
Recruitment in muscle contraction or motor unit recruitment refers to the periodical stimulation or activation of the one or more motor neurons to get the more or enhanced strength in a muscle contraction.
Additional motor neurons or motor units are activated, along with larger motor units to stimulates a higher number of fibers for increased strength of muscle contraction.

Which statement is true?
a) Punnett squares are used to predict dominant allele combinations of a genetic combination.
b) Punnett squares are used to predict all possible allele combinations of a genetic combination.
c) Punnett squares are used to predict the most likely allele combination of a genetic combination.
d) Punnett squares are used to predict recessive allele combinations of a genetic combination.
Answer:
b, the are used to predict ALL possible allele combinations from a cross.
Explanation:
it is merely a table that allows you to predict all the allele combinations in offspring, given the allele content of the parent. It does not tell you which is dominant or recessive , not does it tell you which is more likely.
BUT if you already have dominance or recessive information you can use this to predict phenotype possibilities.
Answer:
it is b because you have to determine if a trait runs in the family to the Punnett squares.

Which are the two agents that are necessary in the formation of metamorphic rocks? erosion and heat heat and lava lava and pressure pressure and heat
Answer:
Pressure and heat
Explanation:
Two agents that are necessary for the formation of metamorphic rocks are pressure and heat. The correct option is D.
What are metamorphic rocks?The secondary rocks known as metamorphic rocks are created when a rock changes as a result of shifting heat and pressure conditions. They come from sedimentary, igneous, or other metamorphic rocks, depending on the kind. Taking Quartzite, Marble, Schist, and Gneiss as examples.
When the sedimentary rock known as limestone experiences changes as a result of an increase in temperature and pressure, marble is created. Marble is frequently used to create monuments, paving stones, and sculptures.
When rocks are exposed to extreme temperatures, high pressures, hot mineral-rich fluids, or, more frequently, some combination of these conditions, metamorphic rocks are created.
Therefore, the correct option is D. pressure and heat.

A cell has a circular chromosome and histone proteins associated with its DNA, but lacks a nuclear membrane. Choose the domain of the cell with the best justification.
A. The cell belongs to Archaea because it has histone proteins, which are present in Archaea and Eubacteria but absent in Eukaryota.
B. The cell belongs to Eukaryota because it has a circular chromosome, which is present in Eukaryota and Eubacteria but absent in Archaea.
C. The cell belongs to Eubacteria because it has histone proteins, which are present in Eubacteria and Eukaryota but absent in Archaea.
D. The cell belongs to Archaea because it has histone proteins, which are present in Archaea and Eukaryota but absent in Eubacteria.
E. The cell belongs to Eubacteria because it lacks a nuclear membrane, which is present in Eukaryota but absent in Eubacteria and Archaea.
Answer:
The correct answer is: D. The cell belongs to Archaea because it has histone proteins, which are present in Archaea and Eukaryota but absent in Eubacteria.
Explanation:
A cell with a circular chromosome and histone proteins associated with its DNA but lacking a nuclear membrane can only belong to the Archaea domain.
Archaea is the domain of ancient bacteria - they have similarities with both Eukaryotes and Eubacteria.
Archaea and Eukaryotes both have DNA associated with histone proteins, but eukaryotes have multiple linear chromosomes, not just a circular one; besides, eukaryotes have a nuclear membrane while archaea do not. On the other hand, Archaea and Eubacteria both have one circular chromosome, but eubacteria don't have their DNA associated with histones.
For these reasons, the cell described is definitely in the Archaea domain.
One g of fecal matter was suspended in 99 ml saline solution (tube 1). After mixing gently but thoroughly, one ml from tube 1 was removed and added to tube with 99 ml saline solution (tube 2). One ml suspension from tube 2 was played in MacConkey agar. After 24 h incubation, 30 red colonies and 50 colorless colonies were counted. Determine cfu/g Gram-negative bacteria in the fecal sample. Your answer must be in scientific notation such as 1.0 x 10^2. Round your answer to the nearest 10th. For example, your answer is 1.675 x 10^5 cfu/g, type 1.7 x 10^5 cfu/g. Put a space before and after the x. The x is lower case.
Answer: the cfu/g Gram-negative bacteria in the fecal sample is C = 3.0 × 10^3
Explanation:
We know that; Gram negative bacteria looks pale reddish in color under a light microscope from Gram staining.
therefore
There are 30 red bacterial colonies counted.
1 mL of from tube 1 was removed and added to tube with 99 mL saline (tube 2) dilution is 1/100.
transferred volume into the plate is 1 mL.
Now, we have to determine the cfu/g Gram-negative bacteria in the fecal sample
Formula to calculate CFU/g bacteria in fecal sample is expressed as;
C = n/(s×d )
where C is concentration (CFU/g) , n is number of colonies , s is volume transferred to plate , d is dilution factor.
so we substitute
C = 30 / ((1/100) × 1)
C = 30 / 0.01
C = 3000
C = 3.0 × 10^3
THERFERE, the cfu/g Gram-negative bacteria in the fecal sample is C = 3.0 × 10^3

Explanation:
Consider an experiment where your goal is to isolate Bruton’s tyrosine kinase (BTK) enzyme from a whole‑cell lysate. You have an affinity chromatography column with a tyrosine kinase inhibitor molecule covalently attached to the beads. The tyrosine kinase inhibitor binds and inhibits BTK. As a result of the experiment, you are able to elute BTK from the column, but in a mixture of other tyrosine kinases. Why are tyrosine kinases other than BTK present in the eluate?
Answer:
Kinase inhibitor has low specificity
Explanation:
In humans, Bruton's tyrosine kinase (BTK) is a protein tyrosine kinase encoded by the BTK gene, which plays key functions in the mechanisms of development, differentiation, and signaling of B-lymphocytes. In the last years, many BTK inhibitor drugs have been developed, including Ibrutinib, Acalabrutinib and Zanubrutinib. It has been shown that kinase inhibitors may have low specificity because these molecules exhibit a high conservation level in the ATP binding pocket, which is known as 'inhibitor promiscuity'.
what features do the sea urchins and sea cucumbers, sea brittle and sea stars have in common that identify them as a echinoderms
Answer:
Whether you are a newly certified diver (if so, we offer our congratulations) or an old salt (good for you, too), odds are you are familiar with the animals known as echinoderms.The feet hold tight to the bottom as muscles within the feet contract, enabling the animal to propel itself. Repeating this process allows echinoderms to travel in a fashion that is “more turtle than hare.”One of the most remarkable traits about echinoderms is their ability to regenerate body parts that have been lost. Many tropical destinations have learned this lesson the hard way. A sea star known as the wnwn of thorns readily preys upon living corals, and a crown of thorns invasion poses a serious, but usually temporary threat, to coral reef ecosystems. A few decades ago, when crown of thorns showed up in big numbers, resort owners asked local divers to go into the water and chop them up. Bad idea. Like many sea stars and brittle stars, crown of thorns not only regenerated lost parts, but in some instances the lost part often regenerated an entirely new animal. The not-surprising lesson here, “Don’t mess around with Mother Nature.” The ability to regenerate is an important part of the survival strategy of many species as they readily sacrifice body parts to escape predation.Sexes are separate in most echinoderms, but they look very similar and distinguishing male from female is a task best left to specialists. Reproduction is most often achieved by spawning as males and females simultaneously release sperm and eggs into the water column where sexual union occurs. The resulting larval life-forms spend from a few days to a few weeks as part of the community of plankton before settling down to live their adult lives on the sea floor.
