Amoeba Sisters Video Select Recap: Mitosis vs. Meiosis Comparison
Could i get help with this?
Answer:
Both mitosis and meiosis occurs in Amoeba.
Explanation:
Both mitosis and meiosis occurs in Amoeba. Those kinds of Amoeba that reproduces through asexual reproduction uses mitosis in which a single parent Amoeba cell is divided into two identical daughter Amoeba cells while on the other hand, Myxamoeba reproduce through sexual reproduction in which meiosis cell division is used. In this type of reproduction, the daughter Amoeba is different from their parents Amoeba.

What is the main concern with persistent organic pollutants (POPs)?
a.
They are only found in plants, and they disrupt photosynthesis.
b.
They quickly break down into more harmful pollutants.
c.
Although they are rarely found, they are very toxic.
d.
They can be concentrated in an organism’s fat tissues.
e.
They are soluble in water and cause large-scale problems.
d. They can be concentrated in an organism’s fat tissues.
This is referred to as biomagnification -- the POPs become more concentrated as they move from one animal to another. This is a main concern because even trace amounts, in animals at the bottom of the food chain, can cause toxicity to animals at the top of the food chain.
Answer:
d.) They can be concentrated in an organism's fatty tissue.
Explanation:
Other reasons:
They have a carbon-based molecular structure, containing highly reactive chlorine
Most are manufactured by humans
They are persistent in environment, they do not easily break it down
Polluting and toxic
They occur in forms that allow them to be transported by wind, water, and sediments for long distances.

7.An experiment was conducted that showd the building blocks of life (amino acids) could indeed be formed by the combination of warm salt water, volcanic gases, and sparks of electricity.
Answer:
The most significant experiment performed to date on the formation of organic molecules remains that of Miller and Urey in 1952 when they sought to test the hypothesis of Oparin and Haldane that the organic building blocks of life emerged from a reducing atmosphere (Miller, 1953). Miller filled a flask with the four gaseous elements of the reductive atmosphere: methane, ammonia, hydrogen and water. He then passed electrical discharges through them to simulate lightning. After 125 h of the experiment, using the equipment available to him at the time, Miller identified several alpha amino acids contained within the residues.
how your innate immunity protects you from the pathogens you encounter.
Answer:
The innate immunity in living organisms protects them from the pathogens they encounter daily.
Explanation:
Pathogens are organisms such as virus, fungi, bacteria, protozoa, worms that causes diseases to its host.
For example, Avian flu is a strain or variant of the Influenza virus which predominantly causes a disease in birds such as chickens. The virus responsible for the Avian flu can be passed from birds to humans; when anyone comes in contact with a bird that is carrying the virus i.e a sick bird with Avian flu.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment ideal to enhance life and proper functionality.
Also, immunization can be defined as the process of boosting an individual's immunity or immune system against antigens (immunogen) which cause diseases by the administration of vaccines.
Basically, immunization helps to improve the functions of the antibodies, B cells, T cells etc.
If a person becomes infected with a pathogen, such as a virus. The internal stimulus that mainly takes place in order for their body to maintain homeostasis is that their core temperature increases. This is because pathogens such as a virus do not thrive or survive in a hot environment; they're naturally allergic to high temperature (heat).

how your innate immunity protects you from the pathogens you encounter.
Answer:
General defenses are the first line of defense and are collectively called: the Innate Immune System. This system is called "innate" because it is genetically encoded, the traits that protect us from infections can efficiently be transmitted to our offspring.The innate immune system recognizes molecular structures that are produced by pathogenic microorganisms. Microbial substances that stimulate innate immunity are often shared by different classes of microbes and are called molecular patterns associated with pathogenic microorganisms
Explanation:
The first defenses that external agents face when trying to penetrate the body are totally nonspecific and are made up of the anatomical, physical, chemical or biological barriers characteristic of each location, while some, such as temperature, are systemic. Between all they make up innate immunity. The importance of these barriers is reflected in the ease with which infections are acquired when one of them fails. Innate cell recognition systems are based on surface or intracellular proteins of epithelial cells, neutrophils, macrophages, and dendritic cells and on soluble cytoplasmic receptors. All these receptors are generally called PRRs (Pattern Recognition Receptors) and bind to PAMPs (Pathogen-associated Molecular Patterns) molecules expressed only by the pathogen (bacterial lipopolysaccharides, carbohydrates and lipoproteins, peptidoglycans, RNA, DNA, etc.). Innate immunity constitutes a less evolved and specific defense than the adaptive one, since the same mechanism (cells, soluble factors, etc.) acts against different agents. Furthermore, repeated exposures to a foreign molecule or agent elicit a similar response and with the same intensity in all of them; that is, it lacks immune memory. The fact that it is a less evolved and specific response is compensated by its speed, since it occurs in hours, and because its intensity is not linked to a previous contact with the foreign agent. Furthermore, its action is essential for the subsequent development of the adaptive immune defense, to which the agent must be exposed once these barriers have been overcome.
Nylon is a material made by humans. A nylon factory released wastewater containing small pieces of nylon into a pond. Some
bacteria in this pond were able to eat the nylon and use it for energy. These bacteria could do this because they had a protein that
could break the nylon down. This protein had developed through a mutation and was not present in any other strain of bacteria.
Which of the following correctly explains the information?
A. Bacteria have the ability to create new proteins to match their environment.
В. Some bacteria learned how to digest nylon, and other bacteria learned from them.
с. The mutation resulted in a beneficial trait that enhanced survival, and offspring inherited it.
D. Materials made by humans are useful to organisms and cause beneficial mutations.
Answer: C. The mutation resulted in a beneficial trait that enhanced survival.
Explanation:
The bacteria was able to "evolve" and adapt to the Nylon being in its environment.
Answer:
The mutation resulted in a beneficial trait that enhanced survival, and offspring inherited it.
Explanation:
Strains of petunias come in four pure-breeding colors: white, blue, red, and purple. White petunias are produced when plants synthesize no flower pigment. Blue petunias and red petunias are produced when plants synthesize blue or red pigment only. Purple petunias are produced in plants that synthesize both red and blue pigment.
The mixture of red and blue makes purple. Flower-color pigments are synthesized by gene action in two separate pigment-producing biochemical pathways. Pathway I contains gene A that produces an enzyme to catalyze conversion of a colorless pigment designated White 1 to blue pigment. In Pathway II, the enzymatic product of gene B converts the colorless pigment designated White 2 to red pigment. The two genes assort independently.
Part A: What are the possible genotype(s) for pure-breeding red petunias?

Part B: What are the possible genotype(s) for true-breeding blue petunias?

AAbb
Aabb
aabb
AABb
AaBb
Answer:
Part A : aaBB
Part B : AAbb
Explanation:
The flower petunia is a beautiful flower. The color of the flower is formed by the action of the two separate genes in the two separate pathways. The gene A produces blue pigments. The gene B produces the red pigment. And when both the genes are present the color looks purple. And when both the genes are recessive, it results in no color.
Thus the pure breeding of the red petunia may have the genotype -- aaBB.
Also the possible genotypes for the true breeding blue petunias is -- AAbb.

please help fast. How do both systematics and taxonomy relate to phylogeny?
Answer: “ Systematics is concerned both with Taxonomy, the naming and classification of life, and Phylogeny, the science and study of understanding the family tree of all life on Earth. ... Systematics, then is the classification of life according to its phylogenetic (evolutionary) relationships.” -http://palaeos.com/systematics/
Systematic is related to the study of the evolution of a species over time and the relationship between them. Taxonomy is the naming and classification of animals and plants. The phylogeny is the study of family trees of every species on Earth, Hence they all are related to each other.
What is taxonomy?Taxonomy includes the study of naming and classifying animals and plants. By seeing the characteristic of a new organism, it is classified and put into kingdoms and groups.
Phylogeny and systematic are related to the evolutionary relationship between them, the family tree, and how an organism evolved over time.
Thus, Systematic has to do with the investigation of how a species changes over time and how they interact. The naming and categorization of plants and animals are known as taxonomy. Phylogeny is the study of family trees. These terms are related to each other.
