Why do scientists that work on producing biofuel from algae need to understand algal reproduction?
Answer:
Due to more production of biofuel.
Explanation:
Scientists that work on producing biofuel from algae need to understand algal reproduction because reproduction of algae is responsible for the higher productivity of biofuel. Algae produce by both sexually and asexually means from the fusion of male and female gametes and from only one parent. Algae needs carbondioxide gas and light for the growth and reproduction so if these factors are present in sufficient amount then the algae increases in growth and reproduce rapidly which leads to higher production of biofuel.
Fuels acquired from biomass is called biofuel. Biomass can be a plant, animal waste or algae. It is a reservoir of renewable energy and can be supplied readily.
Scientists operating on biofuel need to learn about algal reproduction as algae is the major source of biofuel production.The potency of biofuel depends on the generative cycle of the algae.Algae can propagate asexually by means of spores and vegetatively or through sexually by producing the gametes.If the determinants like carbon dioxide and sunlight required for reproduction are present in the right quantity then the algae will thrive and proliferate rapidly, thus increasing biofuel production.Therefore for increasing biofuel production, we need to know the reproductive methods of algae.

what is the definition of the earth's crust
Answer:
“Crust” describes the outermost shell of a terrestrial planet.
Earth's crust is generally divided into older, thicker continental crust and younger, denser oceanic crust. Earth has three layers: the crust, the mantle, and the core. The crust is made of solid rocks and minerals.

B. pupae stage
C)simple life cycle
Question 2
A)breathes through lungs
B. forms a pupa
C. lives completely underwater
The correct answers are A A.
Explanation:
Salamander go through process of metamorphosis that reproductive changes. They have a larvae stage that breathe through gills because the larvae are inform of a fish and gave gills for respiration while the adults breaths through lungs. The larvae stage develops 30 days after hatching and can possibly change into an adult like 60 after hatching.
Answer:
metamorphosis
Breathes through its lungs

Which section of the article BEST explains why the development of CRISPR-Cas9 is significant for the scientific community?
Answer:
It allows the scientists to activate gene expression instead of cutting the DNA.
Explanation:
The development of CRISPR-Cas9 is significant for the scientific community because this development allows the scientists to activate gene expression instead of cutting the DNA. This technique allows the scientists and researchers to study the function of the gene. Before development, Cas9 enzymes produced by the CRISPR system binds to the DNA and cuts it by shutting the targeted gene off so this development of CRISPR-Cas9 enables the scientists to activate gene expression instead of cutting the DNA.
a recipe calls for 1 cup of sugar and 1/2 cup of flour.Zoe uses 1 cup of salt and 1/2 cup of flour.
which kind of mutation is best modeled by zoes version of the recipe
Answer:
Substitution
Explanation:
Given the information in the question substitution seems like the most appropriate answer. Zoe used 1 cup of slat rather than 1 cup of sugar, she substituted sugar for salt.
Insertion is wrong because Zoe did not add another ingredient, there is still only 2 ingredients.
Transition is wrong because, given the information, because the state(liquid or solid) of the ingredients has not changed. Zoe is still use dry ingredients per say.
And beneficial also seems to be wrong because we don't know if using salt instead was beneficial to the recipe or to Zoe.

Explanation:
At high altitudes, air is less dense than at sea level because of decreased air pressure. This means that a person who ascends to high altitudes takes in fewer oxygen molecules per breath. Describe and explain an immediate response that occurs in the circulatory system when a person first reaches high altitudes. Use vocabulary from class.
An immediate response that occurs in the circulatory system when a person first reaches high altitudes is that the heart beats faster to meet the demand for oxygen that the body needs.
What are the main effects of altitude?The higher it is, the worse the symptoms, which include
headacheshortness of breathrapid heartbeatamong othersNot everyone has these symptoms when they go to high-altitude places, but it is also not possible to know who will or will not feel something.
With this information, we can conclude that An immediate response that occurs in the circulatory system when a person first reaches high altitudes is that the heart beats faster to meet the demand for oxygen that the body needs.

how are the new strands of DNA lengthened
Explanation:
New strands of DNA are lengthened by adding new nucleotides at the replication fork.
These methods primarily involve DNA synthesis techniques, such as polymerase chain reaction (PCR) and DNA sequencing methods. However, it's important to note that scientific advancements may have occurred since my knowledge cutoff, and there could be new techniques or technologies available.
PCR is a widely used technique that allows for the amplification of specific DNA sequences. It involves a series of heating and cooling cycles, which enable the DNA to denature (separate into single strands) and then be replicated using a DNA polymerase enzyme. By repeating this process, multiple copies of the DNA sequence of interest can be generated.
DNA synthesis involves the chemical synthesis of custom DNA sequences in the laboratory. This process typically employs a method called phosphoramidite chemistry. It starts with a DNA template strand and adds nucleotides one by one, using chemical reactions to build the new DNA strand. This method allows for the controlled synthesis of long DNA strands with specific sequences.
Modern DNA sequencing technologies, such as next-generation sequencing (NGS), can indirectly contribute to DNA lengthening. During the sequencing process, DNA strands are often amplified and replicated to generate sufficient material for analysis. This amplification step can result in the lengthening of DNA strands.

Explain how a school bus uses all of these energy types.
-Mechanical
-Chemical
-Electrical
-Thermal
Answer:
Mechanical
94 percent of all school buses in America are powered by diesel engines because of their reliability, durability and safety. Almost half of these (46 percent) rely on the cleanest, near-zero emission diesel engine technology.
Chemical
school bus uses petroleum as chemical potential energy.
Electrical
An electric bus draws electricity from the power grid and stores it in a battery that can be recharged once the electricity has been used up. This basically mirrors the way our electronics work. We plug them in and let the battery charge and then use them wirelessly until it's time to charge again
Thermal
They heat the cold coolant from engine's block to 160° F in as little as one hour, then pump it back to the vehicle's engine and heat exchangers. The result: engine is preheated and the vehicle's heat exchangers distribute an abundance of heat to the vehicle's interior.
