You are a mad scientist tasked with the evil job of designing a novel species. This species will be introduced to an ecosystem
and must cause as much damage as possible. What abilities and characteristics will you give this species to make it
successful? Be sure to explain why you choose each aspect. Explain your choice in 3-5 sentences. (4 points)
Answer: The new animal species I would release into an ecosystem would be aquatic animals. One that could affect the water supply in the ocean, causing the collapse of the ecosystem I place my animal in. My animal would be a shark-like creature of the otodontidae shark family with skin so tough, not even a harpoon could pierce, to protect itself from predators. I would give my animal the immortal ability of a genus hydra so it can never be killed. My species would also release toxic chemicals into the water destroying other living organisms in the water and poisoning any creature that drinks the water. The species would thrive without the need for water or substance like other creatures and have the ability to adapt to any situation or environment so it can survive in any ecosystem I were to place it into.
Novel species are newly designed or discovered species. The organism is altered genetically and is different in some characteristics from its original. I will create an aquatic animal.
How an imaginary novel species can be created?For this imaginary question, I will introduce aquatic species in the ecosystem. As it will affect the aquatic ecosystem of the water and will affect the oceanic life.
I will modify and alter the genes of the piranhas family as they are already very dangerous and any modification in them would create monster species. I will combine some of the genes of the other very dangerous animal with that of the piranhas.
Also, I will combine the ability of regeneration and immortality with the new novel species. I will increase their attacking capability and will add some poisonous chemicals to be released while they hunt to kill their prey.
In addition, I will make them capable to survive in terrestrial places as well so that they can even survive without water.

Consider a breeder that mates two heterozygous black Staffordshire bull terriers over the course of three years. The dam eventually produces 16 puppies: 11 are black like the parents, 4 turn out white, and 1 turns out gray colored. As a genetics student, what do you think of this outcome
Answer:
Different colour occur due to heterozygous nature.
Explanation:
Most of the puppies just like parents because the black colour gene or allele is dominant over other colour allele whereas other colour puppies also formed due to presence of heterozygous type of alleles. Other colour occurs due to appearance of recessive allele in the physique of the offspring or formation of hybrids occurs which causes colour other than black and white in the offspring. In the F1 generation all the offspring resembles to the male parent but after this generation some offspring resembles to male, some are hybrids and other resembles to female.

3.List the 3 strengths & 3 Weaknesses of behaviorism.
Answer:
Weaknesses: Many critics argue that behaviorism is a one-dimensional approach to understanding human behavior and that behavioral theories do not account for free will and internal influences such as moods, thoughts and feelings.
Strengths: One of the greatest strengths of behavioral psychology is the ability to clearly observe and measure behaviors. Behaviorism is based on observable behaviors, so it is sometimes easier to quantify and collect data when conducting research.

It is expressed as the amount of electricity consumed per person (kWh), divided by the midyear population. Thus option C is correct.
What determination of a community’s quality of life?Societies are impacted by energy in both positive and harmful ways. It is advantageous for humans to have access to plentiful, affordable, secure, safe, and clean energy. However, the production, distribution, and use of energy can have a severe impact on a society's health, ecology, and economy.
Energy use is inextricably linked to population growth and quality of living. Energy consumption in 2040 may be maintained at 2010 levels by limiting overconsumption. Future energy demand is only little impacted by limiting population increase. Reducing social disparity improves quality of life while using little energy.

different between plant and animal cell
Answer: plant cells are generally more boxy and have a special organelle that an animal cell does not have called the chloroplast. the color plant creates food for the plant during photosynthesis. plant cells also have a larger vacuole than an animal cell.
The light-independent reactions of photosynthesis, also known as the Calvin cycle, must repeat three times in order for a cell to have enough material to construct half a glucose molecule. A variety of molecules are used and produced during this process. Identify the molecules into three categories: molecules brought in and used in three turns of the Calvin cycle, molecules produced during three turns of the Calvin cycle that leave the cycle, and molecules used and regenerated within the Calvin cycle during three turns.
Answer:
- molecules brought in and used in three turns of the Calvin cycle = carbon dioxide (CO2)
- molecules produced during three turns of the Calvin cycle that leave the cycle = Glyceraldehyde-3-phosphate (G3P)
- molecules used and regenerated within the Calvin cycle during three turns = Ribulose bi phosphate (RUBP)
Explanation:
The second stage of photosynthesis, called CALVIN CYCLE, occurs in the stroma of the chloroplast. The processes that occur in this stage can be divided into three stages namely: carbon fixation, reduction and regeneration.
As rightly stated in this question, the calvin cycle must repeat three times in order for a cell to have enough material to construct half a glucose molecule. Hence;
- In carbon fixation, molecules of carbon dioxide (CO2) are brought in and used in three turns of the Calvin cycle. The CO2 combines with a CO2 acceptor called RUBP (ribulosebiphosphate) to produce PGA (3-phosphoglycerate).
- In the reduction stage, PGA is reduced to Glyceraldehyde-3-phosphate (G3P). This G3P molecule is produced during three turns of the Calvin cycle and leaves the cycle to be used to form glucose.
- In the regeneration stage, remaining molecules of G3P are used to regenerate RUBP in order for the cycle to continue. Hence, RUBP molecules are used and regenerated within the Calvin cycle during three turns.

A geneticist studied the genome of a child. The geneticist discovered that the genetic
material of the child had three copies of chromosome 13.
How would the geneticist learn this type of information about the child's genome?
Answer:
through karyotyping
Explanation:
The geneticist can learn information about the child's genome through karyotyping.
Karyotyping is a process of analyzing the genome of organisms by first isolating the chromosomes of the organisms after which they are paired and ordered to provide a snapshot of their entire chromosome.
Thus, through karyotyping, all the chromosome sets of organisms can be analyzed and any abnormality detected. Chromosomes that are similar can be further analyzed and discovered to be copies of each other.
Therefore, the geneticist could have learned the information of the child having three copies of chromosome 13 through karyotyping of the child's genome.

Answer: the answer is c for both
Explanation:
You are involved in an experiment involving fluorescent painting of chromosomes. You observe the following in a nucleus experiencing homologous pairing in metaphase I of meiosis. At appears that four chromosomes have become paired, with each chromosome pairing with two others (centromeres appear as white circles, and the four chromosomes appear in different colors). What is the best explanation of this finding
Answer:
It seems that a reciprocal translocation is going on.
Explanation:
A translocation occurs when a chromosomal fragment changes its location in the same chromosome from the original to a new one. Or when it leaves the chromosome to re-locate in a new different chromosome.
According to this, there are different types of translocations:
Intrachromosomal translocations: Intra-radial: the change in position occurs in the same arm of the chromosome. For instance, 123.456789 → 123.478569Extra-radial: The change in position occurs from one arm to the other of the same chromosome. For instance, 123.456789 → 15623.4789Extrachromosomal translocations:Transposition: not reciprocal interchange. The fragment leaves a chromosome to re-locate in another chromosome. The other chromosome does not send any fragment to the first one. Reciprocal translocation: There is a reciprocal interchange. A fragment of chromosome A goes to B, and a fragment of chromosome B goes to A.Reciprocal translocations might be:
Fraternal: the interchange occurs among homologous chromosomesExternal: the interchange occurs among non-homologous chromosomesReciprocal translocations are easily recognized during meiosis because an association between four chromosomes can be observed. This association is a quadrivalent structure.
During metaphase 1, the centromeres involved in the quadrivalent originate centromeric co-orientation or disjunction.

Hide Assignment Information Instructions INSTRUCTIONS You are bird hunting moths (both dark and light) that live on trees. As you capture the moths most easily visible against the tree surface, the moth populations change, illustrating the effects of natural selection. In this Lab, you will: Predict the color of moth that will survive better on various colors of tree trunks. Understand how camouflage can promote survival. Explain the process of natural selection.
Answer: The theory of natural selection suggests that some members of the population of species have better advantage of others for survival in terms of better phenotypic traits.
Explanation:
According to the given situation, the moths which have color that remain undetected by me as bird has a phenotypic advantage. As I may not be able to observe them on tree trunk or bark or on leaves I can eat only those moths that can be seen through my eyes. I can capture them easily. Such moths which can change their colors in accordance with the color of the tree can camouflage me easily and I cannot observe them and consume them. This promotes their survival over those detectable moths.

name two processes for which dna is responsible for
Answer:
Explanation:
DNA contains the instructions needed for an organism to develop, survive and reproduce.
Contains the genetic instructions for the development and function of living things
The main role of DNA in the cell is the long-term storage of information.
The two major processes that the DNA performs in the cell include:
Storage of genetic information Synthesis of protein for the regulation of cellular activities.The DNA stores the genetic information relating to the cell and ensures that the integrity of stored information is preserved and inherited by subsequent generations. It does this by replicating itself in a semi-conservative way and copies of the replicated DNA are inherited by subsequent generations. This is why the DNA is otherwise known as the molecule of hereditary.
DNA is also at the center of protein synthesis. It forms the template for the synthesis of RNA in a process known as transcription and the RNA forms the genetic codes for the synthesis of protein.
Hence, storage of genetic information and indirect regulation of cellular processes are two major processes attributable to the DNA.
