Answer:
calmodulin
Explanation:
The calcium-modulated protein (calmodulin) is a calcium-binding receptor protein that modulates contractile proteins (i.e., actin and myosin proteins) of the skeletal muscle and non-muscle cells (e.g., platelets). Calmodulin binds to calcium ions (Ca2+) and subsequently activates a number of Ca2+ dependent enzymes (e.g., kinases or phosphatases), which finally activate/deactivate proteins in the calcium signal transduction pathway. Ca2+-ATPase pumps in the membranes of eukaryotic cells release Ca2+ from the cytoplasm and they are autoinhibited by low Ca2+ levels, while calmodulin-binding releases this autoinhibition and thus activates the pumps. In non-muscle cells such as platelets, calmodulin also mediates Ca2+ control of actin-myosin interaction by phosphorylation of the myosin light chain (MLC).
How do particles move when a surface wave passes through a medium?
A. Parallel to the direction of wave motion
B. Perpendicular to the direction of wave motion
C. Both parallel and perpendicular to the direction of wave motion
D. Neither parallel nor perpendicular to the direction of wave motion
Answer:
perpendicular to the motion of the wave.
Explanation:
when in a medium, they only go up and down or back and forth meaning the wave won't ever move the left or right side of the particles, so it is perpendicular
hope this is trusted helper for brainly material
Answer: it’s both parallel and perpendicular to the direction of a wave motion
Explanation:
3) In order for an ecosystem to thrive, it needs to exist in a form of harmony and balance between its biotic and abiotic factors. Describe how small changes to both biotic and abiotic components can have major effects on an ecosystem.
Answer:
Changing temperature causes extinction or removal of organism from that place.
Explanation:
Small changes to both biotic and abiotic components can have major effects on an ecosystem because these are the factors on which the ecosystem depends. For example, if the temperature of the ecosystem increases from its limit, it makes the environment unfavourable for the organism so due to this change, the organism migrated to other location otherwise they will die due to unfavourable environment.
Does the volume increase with trial number, decrease with trial number, or stay about the same? Explain why you think the results are the way there are. There are many possible reasons for the data trend you see. Give some that you think are reasonable.
Hi. You have not informed the experiment that this question refers to and this makes it difficult for your question to be answered. However, I researched your question on the internet and was able to find a question like yours that featured an experiment that assesses the volume of balloons that have been inflated by people's breath.
With the reading of the experiment, we can see that the volume of the balloons remains the same through the number of tests. This is because our lungs tend to express the same amount of air when we blow, just as we tend to breathe the same amount of air in normal situations. This probably happened because all the balloons were filled with air, while the individuals were in the same physical and mental state, that is, they were relaxed and still, which did not change the amount of air they breathed and expelled. This volume of air would be different if the participants in the experiment were exerting some physical effort or were stressed and anxious.
How can a mutation get into a population?
Answer:
Some mutations do not result in changes in the amino acid sequence of the encoded protein and can be described as silent mutations. Other mutations result in abnormal protein products. Mutations can introduce new alleles into a population of organisms and increase the population's genetic variation.

During strenuous exercise, lactic acid fermentation begins because the muscle cells are not getting enough
water
glucose
oxygen
ATP
Answer:
oxygen
Explanation:
Without oxygen aerobic respiration cannot occur. Therefore ATP is produces by anaerobic reparation which is from glycolysis only. Lactate/ lactic acid is formed when glycolysis is the only production of ATP.
Cuanto más fría es la temperatura en un lago, más oxígeno retiene el agua. Daniel se da cuenta de que pesca más peces en un lago que está a menos de 55 grados. Quiere realizar un estudio para capturar la mayor cantidad de peces posible este año. Necesita un poco de ayuda para escribir una pregunta comprobable y una hipótesis. Por favor ayudarlo.
Answer:
- Pregunta ¿la temperatura incide en la cantidad de oxígeno disuelto en el agua del lago?
- Hipótesis: temperaturas más frías están directamente asociadas con un incremento en la cantidad de oxígeno disuelto en el agua del lago
Explanation:
Para poder aplicar el método científico, lo primero que debemos hacer es formular una pregunta sobre algún fenómeno observado en el mundo natural. A continuación debemos formular una explicación posible o 'hipótesis' que permita responder la pregunta que formulamos anteriormente. A partir de la hipótesis podemos diseñar experimentos y/o observaciones empíricas que permitan probar la veracidad de nuestra hipótesis de trabajo. En este caso, por ejemplo, el experimento podría consistir en la medición y posterior comparación del nivel de oxígeno disuelto en el agua del lago durante la temporada de altas temperaturas versus la temporada de bajas temperaturas. Finalmente, los resultados observacionales/experimentales nos permitirán comprobar o rechazar la hipótesis de trabajo (en este caso, nuestra hipótesis es que el nivel de oxígeno disuelto es mayor a bajas temperaturas), obteniendo de este modo una conclusión a partir de nuestro trabajo.

A circular ring of DNA that typically exists in bacteria and that codes for certain traits is known as a/n
Answer is Plasmid.
A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes. Often, the genes carried in plasmids provide bacteria with genetic advantages, such as antibiotic resistance.

Pea plants can have yellow seeds or green seeds. Which conclusion about the meaning of Y is correct if the allele combination Yy is for yellow seeds?
Answer:
yellow and dominant
Explanation:
In genetics, complete dominance occurs when a gene variant referred to as 'dominant allele' completely masks the expression of another allele referred to as 'recessive allele' in heterozygous individuals (i.e., individuals carrying one copy of the dominant allele and one copy of the recessive allele) at a specific locus. In this case, the yellow (Y) allele is dominant for the trait of 'color seed' with regard to the recessive (y) allele, which is responsible for the phenotype of green seeds, and therefore heterozygous individuals (Yy) will have yellow seeds.

Because the imaginary axis of the earth is inclined to the sun at the equator, the northern and southern hemispheres shine in different ways. When it is summer in the northern hemisphere of our planet, then it is winter in the southern hemisphere
Answer:
Yes.
Explanation:
Yes, when it is summer in the northern hemisphere of earth, then it is winter in the southern hemisphere. This change of season occur due to tilting of earth. The season of northern hemisphere and southern hemisphere are different and opposite to each other because both are present at opposite location on the earth surface. The tilting region experience winter season whereas the other regions experience summer due to direct sunlight.
