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.

Which best explains a primary reason for the inability of life to exist in Earth’s early atmosphere? There was insufficient energy from material collisions to change their density. High temperatures during Precambrian time caused surface water evaporation. Volcanic eruptions and comet collisions added different gases to the atmosphere. Available oxygen was used to help create an ozone layer within Earth’s atmosphere.
Answer:
c
Explanation:
on edge
The sentence that best explains the primary reason for the inability of life to exist in Earth’s early atmosphere is " Volcanic eruptions and comet collisions added different gases to the atmosphere".
During the early years of the Earth volcanic eruptions were much more common than they are today. When these volcanoes erupted, they spewed many gases into the atmosphere, including:
Carbon dioxideWater vaporNitrogenHydrogenwhich was directly responsible for the composition of the early atmosphere.
Due to these gases being released into the atmosphere by Volcanic eruptions, causing a severe lack of oxygen, life on Earth was almost unsustainable. It was not until solar radiation and photosynthesis produced oxygen that life became sustainable.

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.

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.
HELP!! Orchids are flowering plants that depend on bees for pollination. A population of orchids in a rainforest has reached its carrying capacity. The size of the rainforest's bee population is a limiting factor of the orchid population. What will happen to the orchids' carrying capacity if the rainforest's bee population decreases?
Answer:
The carrying capacity will decrease because the level of the limiting factor decreases.
Explanation:
Decrease in available resources lead to decrease in carrying capacity of an environment for a population. The rainforest's bee population is a limiting factor for orchid population, decrease in bee population will lead to decrease in orchid population.
Hence, the carrying capacity will decrease due to decrease in limiting factor as the number of orchids that can be sustained by the environment would decreases.

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.

Energy is released from ATP when every phosphate bond is broken. the last phosphate bond is broken. all three phosphate bonds are formed. the last phosphate bond is formed.
Answer:
the last phosphate bond is broken
Explanation:
ATP, is a chemical molecule with the name, Adenosine triphosphate. It is the energy currency of a living cell usd to drive many cellular processes in the body. ATP is produced during the process of cellular respiration.
Adenosine triphosphate (ATP) has an Adenosine molecule (Adenine base and a ribose sugar) and three phosphate groups. However, the energy in ATP is harnessed for utilization when the bond that binds the third phosphate group is broken.
The breaking of the last phosphate bond releases a phosphate group and an Adenosine diphosphate (ADP) molecule.
