Answer:
d. All red and blue chromosomes together make up a diploid set.
f. The chromosomes of one color make up a haploid set.
Explanation:
There are two principal types of cells in the organism:
Diploid cells (2n) Somatic diploid cells (2n) reproduce by the process of mitosis and produce two diploid cells. These cells have a set of chromosomes inherited from the maternal side and another homologous set of chromosomes inherited from the paternal side. This is why the number of chromosomes in these double sets of the somatic cells is diploid, 2n. Germ diploid reproductive cells (2n) also reproduce by mitosis and produce two diploid cells. But can also reproduce by the process of meiosis, suffering a reduction in the number of chromosomes and producing four haploid cells (n). Haploid cells (n)Gametes are the product of germ cell division by meiosis and contain half the number of chromosomes that are in the somatic cells. They have only one set of chromosomes, n (haploid). Their destiny is to merge in the process of fecundation, during which a new diploid cell called the zygote emerges through fertilization. The zygote is a complete diploid cell that suffers successive mitosis and forms a new organism.
- So, through meiosis, the diploid germ cell (2n) produces four haploid cells (n) that are the gametes.
- Through fecundation or fertilization, two gametes (n) merge and produce a diploid cell (2n) that is the zygote.
In the example, red chromosomes belong to one gamete, and blue chromosomes belong to the other gamete, So
a. Red chromosomes make up a diploid set. False, they make up a haploid cell because they only are a single set of chromosomes.
b. All red and blue chromosomes together make up a haploid set. False. They come from two different gametes, which are haploid, so together they make up a diploid cell.
c. Blue chromosomes make up a diploid set. False, they make up a haploid cell because they only are a single set of chromosomes.
d. All red and blue chromosomes together make up a diploid set. TRUE. When both gametes merge (blue chromosomes + red chromosomes) they form a diploid cell.
e. The chromosomes of one color make up a diploid set. False. Nor red or blue chromosomes by themselves can make up a diploid cell, because they are a single set of chromosomes.
f. The chromosomes of one color make up a haploid set. TRUE. One gamete, with one single set of chromosomes, either red or blue, are haploid cells.

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.

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 do continents move?
Answer:
Tectonic plates.
Explanation:
The continents are embedded in the plates, like logs in the ice of a frozen river. As the plates move, the continents move with them. When two continental plates meet, one is dragged down beneath the other.
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.

Explanation:
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.

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.

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.

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?

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.
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.
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.
