Answers
Answer:
2.) attachment below
3.)The paper clips represent ‘five prime’ and ‘three prime’ which indicate the number of carbons in the DNA’s sugar backbone. These two are the distinctive ends of the nucleic acids. The black dots represent the bonds of sugar and phosphate which make up the nucleotides and show the genetic code. These bonds have strong covalent bonds that keep the bonds attached together firmly.

A group of researchers wants to develop an experiment to determine whether a new drug effectively treats cancer. The researchers want to inject the drug in hamsters first to determine whether there are any potentially serious side effects.
Part A: What are some possible ethical issues with this type of testing?
Part B: While conducting the experiment, the researchers find cancer stops spreading, and they declare the new drug is responsible. Is this a good assumption? Explain.
Answers
Answer:
Part A: The animals are used for examining and determining the effect of a particular new drug for the treatment of the diseases and disorders before they are examined over humans. This practice is called as clinical trial.
The ethical issue associated with given type of testing is that animals have right to live and survive. They should not be subjected to the treatment where they experience harm or even death.
Part B: Those assigned to the control take a sugar pill. The only thing you want to vary across groups when you're conducting an experiment is the treatment. Since taking pills is a part of taking medication (the treatment), medical experiments often employ something called a placebo-controlled study where outcomes for those who are randomly assigned to take the medication are compared to outcomes for those who are randomly assigned to take a sugar pill. The sugar pill is expected to have no effect, so it serves as a useful baseline to compare the treatment to.
Answer:
The current code of ethics to be upheld in science experiments are as follows: the experiment must contain a clear scientific purpose, the animals must be housed and provided with care, the animals must be legally acquired, the least amount of suffering must be ensured, and the animals can only be used when it is entirely necessary.
In this paragraph, we can see the plan does not fit the code of ethics entirely- because this is a new drug, we can not be sure that this experiment will not be fatal for the animals, and that they will not suffer tremendously before passing on. The medicine should be tested first on a sample which is not living.

Patterns of inheritance are usually more complicated than what is predicted by Mendelian genetics. Explain four possible exceptions to Mendelian genetics involving the inheritance patterns of a single gene and provide an example of each.
Answers
Answer:
Please find the explanation of the four possible exceptions to Mendelian genetics below.
Explanation:
Genetics, generally, has to do with how genes are inherited or transferred from parents to offsprings. Gregor Mendel, however, explained this concept in his principles of inheritance called Mendelian genetics. There are, however, exceptions to this mendelian principle called Non-mendelian pattern of inheritance i.e patterns of inheritance that do not follow Mendel's principles. Four of them are explained below:
- Incomplete dominance- This non-mendelian inheritance pattern occurs when one allele of a gene does not completely mask its allelic pair, but instead forms an intermediate phenotype. This is in contrast with Mendelian genetics that proposes complete dominance. For example, a red and white flower produce a pink flower (intermediate).
- Codominance- This is another non-mendelian inheritance where two alleles of a gene are simultaneously expressed. For example, roan cattles is a combination of both red and white hairs.
- Multiple alleles: Some traits in a population are controlled by more than two alleles, as explained in mendelian inheritance. Examples of trait controlled by multiple alleles is height in humans.
- Sex-linked inheritance: Some traits are controlled by genes on sex chromosomes i.e. X and Y chromosomes. This genes exhibit inheritance pattern that are different from Mendel's. Example is haemophilia disease controlled by an affected gene on the X-chromosome.

The spinal cord relays messages between the body and the brain. These messages control body functions like movement, bladder and bowel control and breathing. Each vertebra has a pair of spinal nerves that receive messages from the body (sensory impulses) and send messages to the body (motor impulses). The spinal nerves are numbered 1 to 55 from the neck down. The first eight as seen here are the vertebrate and send messages to the back of the head, neck, shoulders, arms, hands and diaphragm.

You overhear your mom and dad talking about having a well installed in your yard. What advice can you offer them about determining the placement and potential effectiveness of the well? Think about what you know about how wells factor into the groundwater systems running below the surface of the Earth.
Answers
Answer:
Built well where water table present nearer to surface.
Explanation:
My advice for them about determining the placement and potential effectiveness of the well is that the well should be installed where the groundwater present nearer to the surface, the reason behind this advice is that minimum work and energy will be used for digging well. If the water table is present very deep, more work and energy will be utilized on the digging of the well. Those areas where more rainfall occurs, the depth of water table is less as compared to arid zones because due to more rainfall more water goes inside the soil and the water table rises.

What term describes parts of the body that are made from different kinds of cell
Answers
Answer:
The term that describes the parts of the body with different kindsof cells is organs, which in turn are made up of different tissues.
Explanation:
The cell is the structural and functional unit of all living beings, with the capacity to multiply and unite to form tissues.
Each tissue is a differentiated or specialized structure, formed by groups of cells of the same type, such as muscle, nerve, connective, cartilage and bone tissue, among others.
The specialized tissues in turn form organs, with specific structures and functions, such as muscle, brain and nerves or bones and joints. For this reason, organs are different body parts, formed by different kinds of cells.
What is a niche, and how does it relate to evolution?
Answers
Answer:
The evolution of species’ niches is a process that is fundamental to investigations in numerous fields of biology, including speciation, community assembly, and long-term regional and global diversification processes. It forms the nexus between ecological and evolutionary questions. Topics as diverse as ecological speciation, niche conservatism, species coexistence, and historical biogeography all rely on interpreting patterns and drivers of species’ niches through time and across landscapes. Despite this importance, a distinct research agenda concerning niche evolution as a discrete topic of inquiry has yet to emerge. Niche evolution is often considered as a sidebar or of secondary importance when addressing questions such as “how did two species diverge?” Basic questions such as “what is a niche,” “what is the biological basis of niche evolution,” “at what scale should we evaluate niche evolution,” and “how can we observe niche evolution at different timescales” have rarely been addressed directly, or not at all in some systems. However, various intellectual threads connecting these ideas are evident in a number of recent and historical publications, giving some semblance of form to a framework for interpreting and evaluating niche evolution, and outlining major areas for future research from an evolutionary perspective. There is a reverse perspective from the macroecological scale as well, with questions involving coexistence, distributions and ranges, food webs, and other organismal attributes

Cholesterol is essential for making a number of critical hormones, including the stress hormone cortisol. Cholesterol is also used to make the sex hormones testosterone, progesterone, and estrogen. 2 The liver also uses cholesterol to make bile, a fluid that plays a vital role in the processing and digestion of fats.
