Answer:
- Hongos: antibiótico penicilina
- Bacterias: producción de insulina para uso humano
- Virus: vectores basados en adenovirus para el desarrollo de vacunas
Explanation:
Los microorganismos son fundamentales para el desarrollo de diferentes tipos de aplicaciones industriales y medicinales. Por ejemplo, la penicilina es una sustancia sintetizada por el hongo Penicillium notatum, la cual es ampliamente utilizada como antibiótico debido a sus propiedades antibacterianas. Las penicilinas son antibióticos del grupo de los betalactámicos que tienen como núcleo un anillo central de beta-lactama, las cuales son capaces de destruir una amplia variedad de bacterias. Por otra parte, las bacterias pueden ser usadas para la generación de moléculas orgánicas con fines médicos. Por ejemplo, cepas de Escherichia coli han sido modificadas mediante técnicas de ingeniería genética con el objetivo de producir insulina humana, una hormona central en el metabolismo de la glucosa. Mediante técnicas de recombinación genética, el gen responsable por sintetizar insulina humana ha sido introducido en bacterias. Las cepas de E. coli son relativamente fáciles de cultivar en el laboratorio y por lo tanto permiten obtener grandes cantidades de esta hormona (insulina). Finalmente, existen ciertas tipos de virus inocuos para nuestro organismo los cuales han sido recientemente utilizados como vectores para el desarrollo vacunas. Mediante esta técnica de ingeniería genética, un determinado vector viral (por ejemplo, un virus de la familia de los adenovirus) es modificado genéticamente con el objetivo de insertar un fragmento de un agente infeccioso o 'antígeno' el cual individualmente es incapaz de producir daño. Las vacunas diseñadas a partir de vectores virales son inofensivas para el organismo pero son capaces de desencadenar una respuesta inmune contra el antígeno recombinante, generando de este modo una memoria inmunitaria en contra el agente infeccioso.

Answer:
Iodine solution test
Explanation:
Add an iodine solution to the leaves, the color will be yellow or brown at first but if it changes to a blue or black that means there is starch present, hope that helps! :)
El vapor se puede transportar a través de la atmosfera. A medida que el vapor se enfría , el agua se condensa en gotitas y forman y forman nubes y da como resultado
Answer:
Precipitación.
Explicación:
El agua se mueve del cuerpo de agua a la atmósfera debido al proceso de evaporación en forma de vapor. A medida que los vapores de agua se enfrían, el agua se condensa en gotitas y forma nubes que resultan en precipitaciones en forma de lluvia y nevadas. Los vapores de agua se vuelven más pesados cuando se condensan y debido a su cuerpo pesado no pueden permanecer en la atmósfera por lo que caen a la tierra en forma de lluvia y nevadas.

Claim: This process uses expensive fertilizers and pesticides to grow pest free crops which may be produced in excess. Explain the reasons why people would go against growing wheat this way.
Your answer: Here are 3 reasons that go against growing wheat this way.
1. The fertilizers and pesticides are expensive and cost farmers a lot which takes away from the revenue that farmers make from growing the crops in the first place.
2. Other then fertilizers and Pesticides its a lot of work as you can see on the chart throughout the year there are many things you must do too keep crops bug free and pest free this reason I'm explaining says that taking and doing all of this work for not pests/bugs is too much and not needed.
3. Fungicide Is needed a lot and incredibly expensive when you used/spray it on crops that much and point goes a lot more for large crops too.
If these reasons don't work, find factors that or counterclaims that go against this method of harvesting wheat. (This is what your supposed too do)
Without knowing the genetic differences of the birds, how can we know that cardinals and finches are likely more closely related to each other than cardinals and finches are to woodpeckers? Cardinals and finches live in more similar habitats. There is no difference in their relatedness; because they are all birds, they all evolved at the same time from a common ancestor. Cardinals and finches have more morphological similarities. Fossil records show that cardinals have been around longer than woodpeckers and sparrows.
Answer:
The correct answer is - Cardinals and finches have more morphological similarities.
Explanation:
To find out the relatedness of the different species or organisms one can use genetic mapping to find precise relatedness, however, if one can not find the genetic differences of the organism one can use the morphological similarities and differences to find out how closely they are related.
Homologous structures and analogous structures are two major morphological characters to find how closely related cardinals and finches are than cardinals and finches are to woodpeckers.

In non-muscle cells, a small increase in the cytosolic concentration of Ca2 can have a dramatic effect on several physiological processes. The presence of a specific protein in the cytosol, however, activates a Ca2 ATPase that serves to return these elevated cytosolic Ca2 levels back to basal levels, thereby maintaining the cell's normal physiology. Which protein is directly involved in activating this Ca2 ATPase
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).
