Your partner has a cardiac muscle cell and you have a skeletal muscle cell. Which one of you will use your electrode more times in one minute
Answers
Answer: I will use the electrode on the skeletal muscle cell more times in a minute than my partner will.
Explanation:
Based on the information given, an electromyograph tracing can be used on order to know when to use the electrode for the scenario explained.
An electromyograph is simply a machine that is used for the detection and the recording of the electrical potential that's been generated by muscle cells when such muscle cells are activated.

In what ways is a eukaryotic cell similar to a city?
Answers
Answer: In many ways, the eukaryotic cell is kind of like a city. I will tell you what each of the organelles in a cell does. Your job will be to try to match each of the cell parts to the parts of a city and explain why they are similar. a) Golgi Apparatus: packages up proteins and labels them for distribution to other parts of the cell.
Each one, like the organs inside your body, fulfills a particular function that is required for the cell to stay alive. Consider the cells to be a miniature city. Because they all do similar jobs, the organelles could represent companies, places, or parts of the city.
What is a cell?Cells are the fundamental building blocks of all life. Gazillions of cells make up the human body.
They support the body's structure, absorb nutrients from food, convert those nutrients into energy, and perform specialized functions.
Each one, like the organs in your body, performs a specific function that is required for the cell to survive. Think of the cells as a miniature city.
Because cell city has jobs that a plant cell does not, it represents an animal cell. In cell city, we believe that a waste disposal plant performs the same function as lysosomes, an organelle found only in animal cells.
Thus, this way, a eukaryotic cell similar to a city.

If Darwin knew of Mendel's work, how might it have influenced his theory of evolution? Do you think this would have affected how well Darwin's work was accepted?
Answers
Answer:
See explanation
Explanation:
According to Darwin, the determinant of the ability of species to thrive in their environment is their ability to develop favourable characteristics which enable them to survive in their environment. This ability to develop favourable characteristics is called natural selection.
These favourable characteristics are passed on from parents to offsprings and are responsible for the perpetuation of organisms having these favourable characteristics in comparison to other members of the same species.
In relation to Mendel's theory, these favourable characteristics could be regarded as Mendel's factors (currently identified as genes). These factors are units of inheritance passed on from parents to offsprings.
If Darwin had an idea of Mendel's work when he propounded his evolution theory, he could have modified his idea of favourable characteristics to imply genes. This would have made his idea more empirical than speculative and led to a faster world wide acceptance of his ideas.

What is an ecological niche?
An ecological niche is the particular habitat of a particular species in an ecosystem. The term was coined by Joseph Grinnell in 1917. The selection of a niche depends on the environmental condition, to avoid competition and availability of the food. The different types of niches are spatial niches, tropical niches, and hypervolume niches.
Habitat is defined as the coexistence of abiotic and biotic things. Examples of habitats are the ocean and forests. A niche whereas is an inclusive space occupied by species in a habitat.

14). Clonal selection and differentiation of B cells activated by antigen exposure leads to the production of ________. A) large quantities of the antigen initially recognized B) vast numbers of B cells with random antigen-recognition receptors C) long-lived erythrocytes that can later secrete antibodies for the antigen D) short-lived plasma cells that secrete antibodies for the antigen
Answers
Answer:
The correct answer is D) short-lived plasma cells that secrete antibodies for the antigen
Explanation:
Each B lymphocyte has an antigen receptor (BCR: B cell receptor), a surface immunoglobulin (IgM or IgD), that binds to specific domains of the antigen called antigenic determinants or epitopes. Only B lymphocytes with a high antibody affinity for the antigen, and which are capable of processing and presenting it, will be positively selected. In this contact between the two cells, an exchange of chemical signals takes place that leads to the activation, clonal proliferation and differentiation of B cells into two sister subclones: one of antibody-secreting plasma cells, and the other of memory primed B cells. Therefore, only these last positively selected B lymphocytes will survive, proliferate and differentiate into plasma cells, synthesizing and secreting antibodies of a single isotypic class, with a unique specificity and high affinity, improving the ability to adhere to the antigen and, thus , neutralize and destroy pathogens.
The Krebs cycle is a series of chemical reactions that: Group of answer choices Metabolize acetyl-CoA and produce ATP, carbon dioxide, and hydrogen ions Metabolize lactate and produces pyruvate, ATP, and hydrogen ions Metabolizes water and produces ATP and hydrogen ions Metabolizes alcohol and produces ATP and water in the mitochondria Breaks fatty acids into two-carbon molecules
Answers
Answer:
Metabolize acetyl-CoA and produce ATP, carbon dioxide, and hydrogen ions.
Explanation:
Cellular respiration can be defined as a series of metabolic reactions that typically occur in the cells of living organisms, so as to produce energy in the form of adenosine triphosphate (ATP).
During cellular respiration, high energy intermediates are created which are then oxidized to make adenosine triphosphate (ATP). Also, the high energy intermediary products are produced at the glycolysis and citric acid cycle stage.
Glycolysis can be defined as a biological process that uses the energy released and stored during the Krebs cycle to form adenosine triphosphate (ATP). Thus, glycolysis is a series of chemical reactions that is typically used to break glucose into pyruvic acid.
Krebs cycle is also referred to as the citric acid cycle (TCA cycle) and it can be defined as a series of enzyme-catalyzed reactions used to release stored energy in most living organisms by metabolizing (oxidation) acetyl-CoA which are typically derived from proteins, carbohydrates, and fats.
This ultimately implies that, the Krebs cycle is a series of chemical reactions that metabolize acetyl-CoA and produce adenosine triphosphate (ATP), carbon dioxide, and hydrogen ions.
Suppose D were dominant and d were recessive, and you could label the D allele in the P generation with a radioactive substance that could be inherited over several generations. You create hybrids by mating your radioactive DD individuals to dd individuals. Finally, you cross two F1 individuals (with the Dd genotype). In 1,000 offspring, how many would you predict would be radioactive?
Answers
Answer:
750 offspring
Explanation:
The correct answer would be 750 offspring.
The D allele has been labeled with radioactive substance.
If you cross Dd and Dd:
Dd x Dd
DD Dd Dd dd
3/4 of the resulting offspring would have, at least, the D allele.
Hence, out of 1000 offspring,
3/4 x 1000 = 750
750 would possess the radioactive label.

Answers
Answer:

Maybe this...
I think
The most likely effect of freshwater pollution is Soil becomes contaminated, causing invasive plant species to crowd out local species. Option C is correct.
Polluted groundwater can seep into the soil, contaminating it with harmful chemicals. These chemicals can then make their way into the food chain, harming both plants and animals. Invasive plant species are those that are not native to an area and can outcompete native species for resources. When soil is contaminated, it can create an environment that is more favorable for invasive plant species, which can then crowd out local species.
Polluted groundwater lowering the porosity of the zone of saturation, is not a direct effect of pollution. Invasive plants developing resistance to overused herbicides, is more likely to be caused by overuse of herbicides, not pollution. Groundwater becoming overused, lowering the water table, is a possible effect of pollution, but it is less likely than soil contamination. Option C is correct.

A large protein that passes through the nuclear pore must have an appropriate A)sorting sequence, which typically contains the positively charged amino acids lysine and arginine. B)sorting sequence, which typically contains the hydrophobic amino acids leucine and isoleucine. C)sequence to interact with the nuclear fibrils. D)Ran-interacting protein domain. Multiple Choice
Answers
Answer:
A)sorting sequence, which typically contains the positively charged amino acids lysine and arginine.
Explanation:
Protein sorting refers to the cellular process by which proteins are transported to their corresponding localizations both inside or outside the cell. A nuclear localization sequence (NLS) is a short amino acid signaling sequence that is able to mediate the transport of proteins into the nucleus. The proteins that are 'tagged' by an NLS sequence can pass through the nuclear envelope via nuclear pores. This sequence (NLS) is typically composed of protein motifs consisting of positively charged lysine (Lys) and arginine (Arg) amino acid residues, which are exposed on the protein surface. In consequence, the NLS sequence is recognized by the importin α/β heterodimer receptor, which transports the NLS-tagged protein into the nucleus. It has been shown that the deletion of the NLS sequence disrupts nuclear import, whereas the fusion of non-nuclear proteins with NLS sequences represents a useful strategy to introduce proteins into the nucleus.

An amino acid analyzer is an instrument used to determine a. the sequence of amino acids in a polypeptide chain b. the presence of modified amino acids in a protein c. the identity of N-terminal and C-terminal amino acids in a protein d. the identities and relative amounts of amino acids in a protein
Answers
Answer:
d. the identities and relative amounts of amino acids in a protein
Explanation:
An amino acid analyzer is an automated machine that is used to determine the identities and quantities of amino acids in a given protein, peptide, and cellular samples. It makes use of the ion-exchange chromatography principle to determine the presence of amino acids. When the chromatogram is obtained, the relative amounts are then determined by the analyzer.
Since proteins are made of sequences of amino acids, the identities of proteins can also be obtained through this method. Ninhydrin, in the chromatographic column, reacts with the present amino acids under an ultra violet detector and is then observed at a wavelength of about 440 - 570nm.
