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.

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.

How do the interactions of the respiratory and circulatory systems help a multicellular organism function.Be specific and tell what organism your are explaining.
Answer/Explanation:
In humans, we breathe in oxygen via the respiratory system. The oxygen enters the lungs. The air sacs in the lungs - the alveoli - are the site of gas exchange in the lungs and are where the circulatory and respiratory systems interact.
The alveoli take in the oxygen, where it diffuses into the capillaries (circulatory system). Blood, which passes through the capillaries takes this oxygen to all the cells in the body. Oxygen binds to haemoglobin in red blood cells, which transport it around the body.
Additionally, blood also transports carbon dioxide back to the alveoli of the lungs, where it diffuses into the lungs and is expelled when we breathe out

desribe the stages of the cell cycle
Answer:
The cell cycle is a 4-stage process consisting of Gap 1 (G1), Synthesis, Gap 2 (G2) and mitosis. An active eukaryotic cell will undergo these steps as it grows and divides. After completing the cycle, the cell either starts the process again from G1 or exits the cycle through G0.

Lake Baikal is the oldest and deepest lake in the world. It is found in the middle of Siberia. In Lake Baikal there are 32 species of sculpin (a type of fish). All of these species are only found in Lake Baikal. You want to understand the evolutionary history of this group of fish and how speciation occurred for sculpin in Lake Baikal. A. What mechanism of speciation do you think has occurred in Lake Baikal sculpin. Provide your answer in the form of a hypothesis. (2 points) B. What are TWO types of additional information you would want to gather in order to test your hypothesis from A? (5 points)
Answer:
The. Two populations of sculpin lived on Lake Baikal, but a genetic change in one of the populations prevented them from crossing, thus creating a new species of sculpin.
B. The additional information I would use to test the hypotheses would be: 1) is there any species of fish similar to sculpin in the same lake? 2) what is the genetic change presented by the sculpins?
Explanation:
My hypothesis about sculpin fish states that sympathetic speciation has occurred. This speciation occurs when two populations of the same species can no longer promote crossings between them, thus creating an evolutionary process, which results in the creation of two distinct species, in the same habitat. I believe that this type of speciation is more common to happen in aquatic environments and in fish, since these environments present less physical barriers than the terrestrial environment. This usually occurs with the existence of genetic modifications within one of the populations. As a result, to test my hypothesis, I would need information about the existence of species similar to sculpin within the same lake, in addition to knowing what genetic differences between them would promote this type of speciation.

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 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

Which are considered two of the special properties that are used to identify certain minerals? hardness and luster magnetism and fluorescence streak and color cleavage and fracture
Two of the unique characteristics that are utilized to identify specific minerals are regarded to be magnetic and fluorescence. Therefore, choice B is correct.
Minerals are chemical compounds that naturally occur in their purest form and have a well-defined composition and crystal structure. A compound is referred to as a distinct mineral if it naturally occurs in a different crystal form. A mineral's chemical makeup can differ depending on the presence of minute impurities that are present in trace amounts.
The physical characteristics of minerals include color, streak, luster, specific gravity, and cleavage; they do not exhibit magnetism. In essence, magnetism is a physical characteristic of minerals; it lacks these components. have no so-called diamagnetic magnetism. Diamagnetic materials include quartz and apatite.

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.
