Q6. A neurotransmitter would have a greater chance of starting an action potential in a post-synaptic neuron by:
opening K+ channels in the post-synaptic membrane
causing a graded depolarization in the post-synaptic membrane
causing a graded hyperpolarization in the post-synaptic membrane
closing Na+ channels in the post-synaptic membrane
Answer:
a
Explanation:
Neurons secrete chemical molecules that act as messenger and takes part in signalling at the arrival of any chemical or electrical impulse are called a neurotransmitter.
The action potential can be started by:
Option a. Opening K⁺ channels in the postsynaptic membrane.
The action can be explained as:
The presynaptic neurons are the active neurons that transmit the impulse from the synapse with the help of neurotransmitters.The resting neurons or the postsynaptic neurons upon receiving the impulse open the channel gates.The postsynaptic receptors interact with the neurotransmitter that leads to the opening or closing of the ionic channels on the membrane.This leads to depolarization of the membrane causing action potential to occur.Thus potassium channels open.

Based on your model, do you think frogs reproduce sexually or asexually? What are the benefits and drawbacks to this
form of reproduction?
Answer:
Frogs reproducesexually and when organisisms reproduce sexually there are benefits which include:
produces genetic variation in the offspring.
the species can adapt to new environments due to variation, which gives them a survival advantage.
a disease is less likely to affect all the individuals in a population.
A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilised by sperm, and then the offspring develop. The benefit of introducing genetic variation into the species , however, outweighs this disadvantage.
Answer:
Frogs reproduce sexually: they require sperm from a male and an egg from a female to produce offspring. This type of reproduction allows for greater genetic variation. But organisms that sexually reproduce need to reach sexual maturity before they can reproduce. They also use energy to find a mate.

¿Qué les explicarías y con qué argumentos basándote en conocimientos científicos para convencerlos de practicar el distanciamiento social y usar mascarilla
Answer:
Experimentos de índole descriptiva han demostrado que diferentes tipos de virus no pueden desplazarse por aire, con lo cual estas estrategias resultan efectivas para evitar su esparcimiento en la población
Explanation:
El distanciamiento social y el uso de barbijos son herramientas útiles para combatir la propagación de muchos virus, especialmente aquellos con un alto indice de infección, como es el caso del nuevo Coronavirus Sars-Cov-2 el cual está asociado a un síndrome respiratorio agudo que puede incluso llevar a la muerte del individuo. Sars-Cov-2 es un virus muy peligroso porque todavía no contamos con un tratamiento efectivo tal como, por ejemplo, una vacuna que permita generar una respuesta inmunológica permanente contra el virus. De este modo, es imprescindible evitar la propagación del virus hasta que la comunidad científica pueda desarrollar un tratamiento efectivo.
how are the respiratory and circulatory systems connected
Answer:
The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.
The respiratory and circulatory systems bring oxygen and nutrients to the cells. The respiratory and circulatory systems work together to maintain homeostasis. The respiratory system moves gases into and out of the blood. The lungs contain the bronchi, bronchioles, and alveoli.
The circulatory and respiratory systems work together to maintain homeostasis.

Do you know the Transcription factor name for lapF and naphthalene dioxygenase?
Answer:
The LapF gene encodes one of the largest proteins from Pseudomonas putida, it is required for the bacterial colonization on the solid surfaces; while naphthalene dioxygenase is an enzyme required for the process of aerobic degradation of naphthalene.
Explanation:
LapF is a gene of Pseudomonas putida that is critical during the process of plant root colonization. Mutations in this gene have shown to reduce the ability to colonize plant tissues. On the other hand, the naphthalene dioxygenase gene is also encoded by the genome of Pseudomonas strains. The naphthalene dioxygenase protein catalyzes the hydroxylation of different substrates, however, this enzyme is widely known for acting during the degradation of naphthalene, an organic chemical compound that is toxic in humans.

Read the passage: Genetically Engineered Corn. Then 1. Explain what Bt corn is and how it is made. 2. Describe the benefits of Bt corn. 3. Describe the risks of Bt corn. 4. Make an argument for or against the use of Bt corn and provide support for your position.
1. Bt maize is a genetically modified maize. It is produced through biochemical techniques and with the use of biotechnology that allows genes of Bacillus thuringiensis bacteria to be introduced in the DNA of corn. These genes allow Bt maize plants to produce a toxic protein specific to certain groups of insects.
2. With the production of this protein, Bt corn becomes immune to attack by these insects. As a result, the use of pesticides in the corn crop is reduced, which makes production healthier and avoids side effects on the soil. In addition, it prevents the production of corn from falling due to the attack of insects.
3. Among the disadvantages, we can say that Bt maize does not control all the pests that attack maize, only a few, which allows maize to be attacked. It can also trigger evolution in pest species that are immune, creating a toxin-resistant species. Finally, it can create contamination in wild maize crops (that is, those that have not been genetically modified), ending diversity.
4. I believe that the use of Bt corn is favorable. This is because it allows a greater production of food to meet our need and increasingly intense demand for food. However, it is necessary to affirm that the use of this corn needs regulation and inspection, mainly in the big industries that can harm the small producer.

Explanation:
A person in a dark room looking through a window can clearly see a person outside in the day light . But a person outside cannot see the person inside
Explanation:
The explanation for this is that the space outside is illuminated with light from the sun. The person inside has either a lesser or no illumination at all. The dark inside room appears dark, and darkens the surface of the window facing inside, making it act like the silvered surface of a mirror. When the outside observer looks at the window, the window acts as a mirror, reflecting the light from the sun onto the eyes of the outside observer. For the inside observer, some of the illumination from outside finds its way inside, since the outside window surface is well lit, carrying with it the sensation of vision onto the eyes of the inside observer.

In what ways are fats and steroids similar to each other, and in what ways are they different? Fats and steroids are both hydrophilic lipids, but fats help with metabolism while steroids provide insulation. Fats and steroids are both hydrophobic lipids, but fats serve as energy while steroids serve as hormones. Steroids contain a four-carbon ring while fats consist of glycerol and fatty acids, but both are proteins. Steroids help with transport while fats store energy, but both are proteins.
Answer:
Fats and steroids are similar because fats & steroids are both lipids & are both hydrophobic. They are different because fats store energy for molecules & steroids function as a messenger around the cell membrane.
