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.

The allele of the human transport protein associated with light skin is found almost exclusively in people with European ancestry. The other common allele for darker skin, which appears to be the ancestral allele, is found in people with African ancestry. What is a plausible explanation for how the lighter-skin allele came to be so common in those with European ancestry
Answer:
See Explanation
Explanation:
Darwin's theory of natural selection has it that organisms that are better adapted to their environment happen to survive and reproduce passing on their favorable characteristics to their offspring.
It must have been that a gene mutation occurred in the ancestors of the Europeans which led to the appearance of the allele for lighter skin.
This trait became favorable in their environment and people that had it were able to survive and pass the trait on to their offspring hence it became predominant throughout the population.

1. How do radiation, conduction, and convection affect the atmosphere?
2. How does greenhouse effect warm the earth?
Answer:
1. radiation, conduction and convention all play a roll in moving heat between earth's surface and atmosphere because since air is a poor conductor, most energy transfers by conduction occuring right near the earth's surface. Conduction directly affects air temperature only a few centimeters into the atmosphere. convection works to heat the troposphere. Durring the day, the sun's radiation heats the earth's surface. the land becomes warmer than the air. Air near the Earth's surface is essentially warmed by both radiation and conduction.
Which of the following best compares Linnaeus's classification system to the classification system developed by Carl Woese and his colleagues in the 1990s?
Linnaean taxonomy classifies organisms into kingdoms based on physical traits, while Woese's classification sorts organisms into domains based on genetic differences.
Linnaean taxonomy classifies organisms into domains based on complexity, while Woese's classification sorts organisms into kingdoms based on method of obtaining nutrients.
Linnaean taxonomy classifies organisms into realms based on geographic location, while Woese's classification sorts organisms into domains based on method of reproduction.
Linnaean taxonomy classifies organisms into taxa based on size, while Woese's classification sorts organisms into kingdoms based on physical traits.
Answer:
The correct answer is - Linnaean taxonomy classifies organisms into kingdoms based on physical traits, while Woese's classification sorts organisms into domains based on genetic differences.
Explanation:
Linnaean classification is set up by Carl Linnaeus which is used to divide and organized organisms into different groups according to some similar basic features such as physical traits. It was the most basic type of classification.
The classification of Carl Woese was based on the different genetic differences to categorize or group organisms. This was a three-domain system that includes Bacteria, archaea, and eukarya.
Answer:
Linnaean taxonomy classifies organisms into kingdoms based on physical traits, while Woese's classification sorts organisms into domains based on genetic differences.

Some male peakcocks used to have bright and large tails while others had dull, smaller tails. Female peacocks will only mate with the ones that have the brightest and largest tails. Explain how this would impact the offspring of male peacocks over time.
Answer:
Over time, most males will have bright and large tails. Females only mate with males carrying these traits, and so natural selection will favor them.
Explanation:
Bright and large tails are traits that reflect the genetic quality of males. So individuals with the most vibrant color and length express better capabilities of finding food, competing for resources, competing for males, among others, are the best option to mate and to ensure successful offspring.
The brightest and largest tails are, the better chances males have to mate and pass their genes to the following generations. So the organism spends energy and resources to produce more vibrant colors and longer feathers to enhance mating chances.
Females must ensure their reproductive success, so sexual selection is the pressure modeling males in this species. Females will only choose individuals with the better genetic charge to mate -individuals with brightest and largest tails-, so their progeny can have better genes and higher survival probabilities.
Males with the brightest and largest tails will mate and reproduce. They will pass their genes to their progeny. Male offspring will also have bright and large tails because they inherit these conditions from their parental. These male offspring will also pass their genes to the progeny, and so on. The frequency of the alleles that express these traits will increase in the population. Natural selection is favoring these alleles. So over time, there will be much more individuals with bright and large tails than individuals with dull and small tails.

Which process produces a greater number of offspring?
chromosome duplication
asexual reproduction
gamete formation
sexual reproduction
Answer:
asexual reproduction
Explanation:
Sexual reproduction produces a greater number of offspring compared to asexual reproduction, chromosome duplication and gamete formation.
What is the involvement in sexual reproduction ?This is because sexual reproduction involves the combination of genetic material from two parents, resulting in offspring that have a unique genetic makeup.
This increases the number of possible genetic combinations and thus the number of offspring produced. Chromosome duplication and gamete formation are involved in the process of sexual reproduction, but neither produces offspring by itself.
Chromosome duplication is the process by which one cell splits into two identical cells, each with the same genetic material. Gamete formation is the process by which reproductive cells such as sperm and eggs are formed.
These cells then combine during sexual reproduction to form a new organism. Asexual reproduction, on the other hand, involves a single organism producing offspring that are genetically identical to itself. This means that the number of offspring produced is limited compared to sexual reproduction.

How might a plant cope with the fact that the Calvin cycle uses more ATP than NADPH, yet produces roughly the same amount of both energy intermediates in photosystems I and II? Group of answer choices Electron flow rate can be increased, increasing both ATP and NADPH production. Plants often increase the amount of NADP reductase, thereby increasing NADPH production to match ATP output. Increase the electrochemical gradient for H+ across the thylakoid membrane, producing more ATP but not NADPH. Photosynthesis can revert from a noncyclic to cyclic electron flow, producing more ATP than NADPH. More pigment can be rapidly created for greater photosynthetic capacity, producing equal amounts of ATP and NADPH.
Answer:
Photosynthesis can revert from a noncyclic to cyclic electron flow, producing more ATP than NADPH.
Explanation:
A Calvin Cycle is defined as a process by which various plants and algae takes carbon dioxide from the air and turns it into sugar, the food which the food autotrophs needs to grow. The Calvin cycle is required for every living being on earth to survive.
Both the ATP and the NADPH are required by the Calvin cycle. It occurs in the chloroplast stroma of the plants. Calvin cycle uses more amount of ATP than the NADPH and produces roughly same amount of both the energies. Photosynthesis may revert from the noncyclic to the cyclic electron flow and it produces more ATP than NADPH.
A father sheep has curly wool while a mother sheep has straight wool. Which of these statements explains why one of their baby lambs has curly wool?
Answer:
This means that the baby sheep received the same set of genes as the father sheep giving it curly wool.
Explanation:
This means that the baby sheep received the same set of genes as the father sheep giving it curly wool.
OR if the baby sheep received a mixed set of genes , one from father , the other from mother , the gene of the father is dominant over the gene of the mother and it has given the baby sheep curly wool.
During fertilization the baby must have received the same set of genes as those of its father. If the baby has received a mixed set of genes then the genes of the father are dominant over the genes of the mother resulting in curly wool.
The fathers gene may be dominant due to environmental circumstances or other factors.
Answer:
Explanation:The baby lamb inherited its copies of the gene for wool shape from its father and not from its mother. Just like its father’s genes, those genes instruct for proteins that connect in ways that make its wool curly.
