Answer:A
Explanation:
The order of stars from closest to farthest from Earth is as follows:
Star Y, Star Z, Star X.Thus, the correct option for this question is D.
What is Star?Star may be characterized as a huge ball of blazing gases in space that is typically observed from the earth as a point of light in the sky at night. It is a type of astronomical object.
As we relate the brightness of a star with respect to the distance, it is found that the closer a star is, the brighter it will appear in the sky. So, a Star Y is the brightest, it will closer to the earth. With this sense of knowledge, options 1 and 2 are eliminated.
Star X is larger than star Z, so, star Z is found to be closer than Star X. With this, option 3 is also eliminated.
Therefore, the correct option for this question is D.

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

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.

please help fast. How do both systematics and taxonomy relate to phylogeny?
Answers
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.

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?

Answers
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.

Answers
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.

All of the following apply to estuaries EXCEPT: There provide very valuable breeding grounds for commercially important fish and shellfish. There is no salinity in estuarine ecosystems due to large supply of fresh water from a river. Plants and algae that grow here have high tolerance for changing environmental conditions like salinity and light penetration. These coastal ecosystems provide a barrier against the ocean during storms.
Answers
Answer:
There is no salinity in estuarine ecosystems due to large supply of fresh water from a river.
Explanation:
An estuary is a semi-closed body of water where fresh water and sea water meet and merge. Even though they are not a habitat to diverse species, they are very valuable breeding grounds and are one of the most productive environments. It is true that plants and algae that grow there have high tolerance for changing environmental conditions like salinity and light penetration because fluctuations happen from time to time because of the influence of the tides. And because of the partially enclosed nature of estuaries, there is provision for a barrier against the ocean during storms.
But despite the supply of fresh water, there is actually salinity in estuarine ecosystems which also varies depending on the concentration of sea water to fresh water.

how your innate immunity protects you from the pathogens you encounter.
Answers
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).

Write a program that simulates the growth of parasite population in an animal over time. Each parasite organism reproduces itself at some time interval. Animals may undergo drug treatment to inhibit the reproduction process, and clear the parasites from their body. However, some of the parasite are resistant to drugs and may survive.
Answers
Answer:
Good environmental conditions and food availability.
Explanation:
Good environmental conditions and food availability are the factors that simulates the growth of parasite population in an animal with the passage of time. Yes, drug can reduces the population of parasites but all parasites can't be removed because some gain resistance against that chemical which allows them to survive in that environment so good environmental conditions and food availability increases population of parasite.
