The sides of the stepping stool are made of rotating sugar and phosphate particles. The sugar is deoxyribose. The rungs of the stepping stool are sets of 4 sorts of nitrogen bases. Two of the bases are purines-adenine and guanine.
how does the antigen-antibody complex protect the body
Answer:
Explanation:
the antibodies destroy the antigen (pathogen) which is then engulfed and digested by macrophages. White blood cells can also produce chemicals called antitoxins which destroy the toxins (poisons) some bacteria produce when they have invaded the body.
When is the production of genetically identical offspring a disadvantage? Explain your reasoning.
Answer: In an unstable or unpredictable environment asexually-reproducing species may be at a disadvantage because all the offspring are genetically identical and may not have the genetic variation to survive in new or different conditions. In an unstable or unpredictable environment asexually-reproducing species may be at a disadvantage because all the offspring are genetically identical and may not have the genetic variation to survive in new or different conditions.
Explanation:
The correct answer for the given question about Asexual Reproduction is "Production of genetically identical offspring is a disadvantage in an unstable or unpredictable environment".
What is Asexual Reproduction?Asexual reproduction refers to a type of reproduction when a child is born to a single parent. The newly created people are clones of their parents since they have the same genetic and physical characteristics.Both multicellular and unicellular species can reproduce asexually. There will be no gamete fusion involved in this procedure, and the number of chromosomes will remain the same. With the exception of specific situations where there is a possibility that a rare mutation may occur, it will inherit the same genes as the parent.So we can conclude that as all of the offspring are genetically identical and could not have the genetic variation to thrive in novel or changing environments, asexually reproducing animals may be at a disadvantage in an unstable or unpredictable environment.

Is DNA replication always a foolproof process? Explain your answer.
Answer: No. Although many proteins check the DNA for damage or errors, damaged regions can still be replicated. This may result in gene alterations and serious complications for the organism.
Explanation:
No, replication is not always a foolproof process although many proteins look for DNA damage or mistakes, damaged areas can still replicate. This can lead to gene rearrangements and serious problems in the body.
Some mutations are caused by mistakes in DNA replication. DNA replication isn’t always 100% complete. Sometimes, an incorrect base is inserted into the new DNA strand. This incorrect base can become permanent.
Breaks in DNA are caused by DNA replication errors, particularly those in regions that are difficult to replicate, known as fragile sites.
Breaks in DNA can cause cancer, mainly because they increase the risk of chromosome fragments rearranging themselves and activating genes that cause uncontrolled cell division.

As the lock for the door opens you enter another room. This one has plain cement walls with huge silver and copper pipes running from floor to ceiling. The room reminds you of a basement mechanical room even though you have just gone upstairs. Everywhere there are old wooden crates and piles of gears of all sizes, springs, gages and the hands of old clocks. As you gaze around the door you just entered closes and will not open.

In 2-3 sentences, explain how crossing over and independent assortment in sex cells affect the appearance of the fully developed organism.
Answer:
Explanation:
Crossing over and independent assortment in gametes (sex cells) can lead to genetic variation in the DNA of these gametes and lead to offspring looking different from their parents. Crossing over is the exchange of DNA between a pair of homologous chromsomes (the mom and the dad) which results in recombinant chromsomes that have new combinations of genes. Independent assortment refers to the lining up of chromsoomes along the metaphase plate in meiosis 1, and this can lead to different combinations of gametes.

I believe the answer is white blood cells
When a foreign substance enters the body, foreign substance-specific proteins produce white blood cells (WBC). Hence, option C is correct.
What are white blood cells?The immune system of the body includes white blood cells. They support the body's defenses against illness and infection. Granulocytes (neutrophils, eosinophils, and basophils), monocytes, and lymphocytes are different types of white blood cells (T cells and B cells).
Blood is filtered and monitored by the thymus. T-lymphocytes, a type of white blood cell, are produced by it.
White blood cells (WBCs) defend against bacterial, viral, fungal, and other pathogen infections (organisms that cause infection). The neutrophil is a significant kind of WBC. These cells are created in the bone marrow and circulate throughout the body in the blood. Hence, option C is correct.

Compare the Three General patterns of population dispersion
Answer:
Explanation:
There is Uniform dispersion, where the individuals in a population are more or less evenly distributed. Also, there is Random dispersion in which individuals are distributed randomly, meaning there is no plan. Finally, there is Clumped dispersion, where individuals are just distributed in groups. Hope it helps x.
The three general patterns of population dispersion are as follows:
Clumped: Variance/mean is greater than 1.Random: Variance/mean is equal to 1. Spaced: Variance/mean is less than 1. What is Population dispersion?Population dispersion may be characterized as the process of spatial distribution and arrangement at any particular moment of the individuals of a certain species. It generally governs the spacing of individuals with the environment at a given time.
Clumped type is the most common type due to attraction. In a random type, the facts of attraction or repulsion do not favor. Spaced type of population dispersion is also known as uniform.
It is generally present in artificial ecosystems or cultivation. Uniform patterns of dispersion are generally a result of interactions between individuals like competition and territoriality.
Therefore, the three general patterns of population dispersion are well described above.

Once anything passes through the event horizon, from the perspective of that
object, nothing would change.
True or false
Answer:
True
Explanation:
The event horizon of a black hole is where gravity is such that not even light can escape. This is also the point I understand that according to Einstein time dilation will be infinite for a far-away-observer.
The statement "once anything passes through the event horizon, from the perspective of that object, nothing would change" is true.
What is horizon?The horizon would be the line that appears to divide a celestial body's ground from its own sky when observed by an observer standing on or close to the body's surface.
What is event?An event would be the collection of results from an experiment.
