Answer:
When the first stage separate, then it will not descend further and it will fall away. It would not be able to launch into air.
The first stage actually help to release it from shell, the first stage of multistage rocket help it to sprout.
If the first stage runs out of the fuel, then there will be no combustion in rocket and it will not ascend further into next stages.
If the second and third stage run out of the fuel then the next 4th and 5th stages will happen to a cessation and there will be a likelihood for it to fall down to earth.

Do you think Biotechnology can be used in anyway in a case where someone has been bit by a venomous snake? If so how?
Answer:
Snake biting is a major public health problem for low-income countries. Till now only antiserum derived from animals are use for the treatment against snakebite venom.
But there are many innovation in biotechnology to manufacture antivenoms against venomous snake. Some of the innovations are as following:
Use of DNA immunisation techniques: In this technique, horses are immunised with toxin-encoding DNA and then antivenom is prespraed from their DNA.Recombinant antivenoms: in this technique antibodies in the animal-derived antivenom are replaced with recombinant human version and then entivenom will be prepared by cell cultivation.These innovation in biotechnology for the preapartion of antivenoms are easier to produce and more cost-effective.

Beyond their role in energy transfer, what other benefit do microorganisms that act as producers provide for ecosystems?
How are microorganisms involved in the movement of nitrogen from the atmosphere to the bodies of other organisms? Why can’t other organisms just get nitrogen from the air?
What is the benefit of using marine microorganisms such as Dumaliella tertiolecta to produce biofuels instead of using plants?
Answer:
The microorganisms present metabolic wastes that serve as the primary source of food for other living things.
Bacteria that live free in the soil or in symbiosis with plants are essential to fix nitrogen, both nitrates and ammonia. These bacteria take nitrogen directly from the air, originating compounds that can be incorporated into the composition of the soil or living beings.
This property is restricted only to prokaryotes and is widely distributed among different groups of bacteria and some archaeobacteria. It is a process that consumes a lot of energy that occurs with the mediation of the enzyme nitrogenase, which the rest of the living organisms that cannot do or comply with this process is because they lack said enzyme.
Dunaliella is a genus of microscopic algae of the Chlorophyceae class and of the order Volvocales. All are unicellular, although with very varied morphologies.
Morphologically, its main characteristic is that they lack a rigid polysaccharide cell wall.
The ecology of this genus of green algae is characterized by its high tolerance to salinity, with eukaryotic organisms having greater tolerance to salt. They are euryhaline, adapted to salt concentrations from 50 mM NaCl to almost 5.5 M NaCl.
Explanation:
By nitrogen fixation is meant the combination of molecular nitrogen or dinitrogen with oxygen or hydrogen to give oxides or ammonia that can be incorporated into the biosphere. Molecular nitrogen, which is the majority component of the atmosphere, is inert and not directly usable by most living things. Nitrogen fixation can occur abiotic (without the intervention of living beings) or by the action of microorganisms (biological nitrogen fixation). Fixation in general involves the incorporation into the biosphere of a significant amount of nitrogen, which globally can reach about 250 million tons per year, of which 150 correspond to biological fixation.

What kind of damage are coniferous trees resilient to
Answer:
The trees acclimate to the cold in the winter, but rapid temperature changes can still cause damage. New growth on trees and seedlings are more vulnerable to freezing damage. If a cold snap comes in the spring after new buds begin to grow, they can be killed.

A farmer has applied a pesticide to control a pest population that is affecting her crops. The pest population has reacted as shown below.
A chart begins with 4 green bugs and 1 brown bug. The brown bug survives and produces brown offspring.
Which best describes the process that the pest population has experienced due to this environmental change?
genetic diversity
natural selection
natural resistance
gene flow
The correct answer is option B. natural selection.
What is Natural Selection?Natural selection is a natural process in which well-adapted organisms tend to survive and reproduce more than less-adapted organisms. For example, tree frogs can be eaten by snakes and birds. This change means that some individuals have more environmentally-adapted traits than others, and their offspring are scarce. There is no doubt that natural selection has shaped the evolution of humankind in our farther past.
Natural selection is an inevitable result of three principles. Most traits are inherited, producing more offspring than can survive, and offspring with more favorable traits survive and have more offspring than individuals with less favorable traits.

Explanation:
how does predation cause stability in an ecosystem
Answer:
Predation makes sure that no species becomes overpopulated.
Explanation:
For example, between a fox and a rabbit. If the fox was not the predator, the rabbit population would be out of control. Rabbits eat grass and stuff so too many rabbits will eat all the grass. There will be a chain effect. Foxes are needed to control the rabbit population and restore stability in an ecosystem

On the basis of these data, which group of robins most likely shares a most recent common ancestor
with the Norfolk Island robins?
Hello. You forgot to enter the necessary data for this question to be answered. The data are shown in the figure attached below:
Answer:
Red-capped Robin is the group of Robins that share a more recent common ancestor with the Norfolk Island robins.
Explanation:
Red-capped Robin is the group of Robins that share a more recent common ancestor with the Norfolk Island robins, this can be seen by the degree of genetic similarity between these two species, since the Red-capped Robin has 98.2% of genetic similarity .
When two species have the same common ancestor, these species have great genetic similarity and the more recent this ancestry is, the greater the genetic similarity between the species.

Why is it more ethical to test for the waste products of respiration rather than the reactants
Answer:
The knowledge of simple biological reactions tells us that the product of reactions results from the complete or partial use of the reactants. In some reversible reactions, products can be converted to reactants in equal volume. Hence, in reactions that cannot be reversed, as evident in respiration, its waste products can be used to indicate that indeed respiration did take place. When glucose is consumed it is broken down through a series of reactions to give carbon dioxide and water as waste products.
