Answer:
2) plasma membrane
Explanation:
The structure that separates the cell from its surrounding is plasma membrane, the correct option is 2.
What is plasma membrane?The plasma membrane, also renowned as the cell membrane, is the membrane located outside all cells that distinguishes the cell's interior from its surroundings.
A cell wall is attached to the plasma membrane on the outer of the plasma membrane of bacterial and plant cells.
The semi-fluid living matter in the cell is called protoplasm or in other words simply plasm. This living matter, or one can say plasm, is contained within the plasma membrane, a biological membrane.
Lipids which are phospholipids and cholesterol, proteins, and carbohydrate groups attached to some of the lipids as well as proteins are the primary components of the plasma membrane.
A phospholipid is a sort of lipid that is created by glycerol, two fatty acid tails, and a phosphate-linked head group.
Thus, the correct option is 2.

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.

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.

(PLEASE HELP!!!) Suppose scientists genetically modified a species of algae to produce more oil. This algal species reproduces asexually. Will all of the offspring of the genetically-modified algae also produce more oil? How do you know?
Answer:
Yes all of the offspring of the genetically-modified algae would produce more oil.
Explanation:
When an organism is genetically-modified to reproduce asexually, it makes exact copies of itself since it is the only one passing genes whereas if normal sex were to occur and both parents would pass 50%-50% of their genes down to the child.
A 35-year-old woman comes to her dentist complaining of tenderness and pain in her cheek near the parotid gland, as well as bad breath and a foul-tasting mouth at meal times. A radiopaque fluid is injected into the parotid duct system through cannulation, and this sialography of the parotid duct confirms blockage by a calculus (sialolith). What muscle, through which the parotid duct passes, is most likely causing the stenosis where the sialolith now resides, blocking the drainage of the parotid duct
Answer:
A Buccinator. I hope this helps.
Explanation:
Modern organisms in similar environments often have similar physical
features. For example, the Australian wombat and North American
badger, Selective pressure from similar environments over time led to
these similar
vestigial features
Ccreations,
homologous features,
analogous features,
Answer:
analogous features
Explanation:
Pressure from similar environments on the organisms over time led to these similar analogous features because of the similar environmental conditions for organisms leads to the physical features that are similar in structure and function. Analogous structures are the structures which are similar in appearance in unrelated or different organisms. These structures have similarities because they perform the same job and not because they share common ancestry.

Describe the Lytic cycle.
No dam links
Answer:
Ok here ya go
Explanation:
The lytic cycle is one of the two cycles of viral reproduction, the other being the lysogenic cycle. The lytic cycle results in the destruction of the infected cell and its membrane. Now during the lytic cycle of virulent phage, the bacteriophage takes over the cell, reproduces new phages, and destroys the cell. T-even phage is a good example of a well-characterized class of virulent phages.

2. One effect of the Hedgehog gene is to make cave tetras go blind. What is another effect it might have?
Answer:
these are odd questions....
Explanation:
1. they are curious about how they get blind
2. the quills
Answer:
1.The first hypothesis is that blindness gives the tetra some sort of evolutionary advantage. That advantage might be the result of pleiotropy, which is when multiple effects are caused by the same mutation in one gene. Scientists think that the mutation that causes blindness in the tetra might also cause a "seemingly unrelated change in the fish that is beneficial."
2. Another effect it might have is to improve cave tetras' sense of smell.

Why is adequate lighting necessary in a balanced aquarium?
a. Fish need light to see their food.
b. Fish take in oxygen in the dark.
c. Plants expel carbon dioxide in the dark
d. Plants grow too rapidly in the dark.
Answer:
A. Fish need light to see their food
Explanation:
B is incorrect because fish take in oxygen constantly to respirate. If they only took in oxygen when it was dark they would die.
C is incorrect because expelling CO2 is also a constant process as a part of the reactions that take part inside living organisms, so it happens constantly (a bit like B)
D is incorrect because plants need light for food (photosynthesis) and would most likely die or have stunted growth if left in the dark.
A is correct because when it is dark, fish rely on other senses to find food as most fish cannot see as well in the dark, therefore when they have light they can see their food more easily.

If an acorn falls off a tree, is it living or non-living??
Answer: living
Acorns are still alive even off the tree and eventually grow into plants in the right conditions.
Answer:
Acorns are alive. Acorns live and breathe. Since they have no teeth and claws, acorns defend themselves with have chemicals called tannins. Because acorns decompose slowly, some gardeners compost them separately from other materials that break down more rapidly. Others grind them before composting them, as this speeds up decomposition.
