Answers
Answer:
The following images of different types of bacteria are attached here-
1- Single round bacterium- Cocci
2- Single rod-shaped bacterium- Bacilli
3- Cluster of round bacteria - Staphylococci
4- String of rod-shaped bacteria- Streptobacillus
5- Comma-shaped bacterium- Vibrio
6- Corkscrew-shaped bacterium- Spirillium
Explanation:
1- Single round bacterium- Cocci -Any bacterium or archaeon that has a circular, ovoid, or usually round shape is a coccus (plural cocci). Cocci may develop in pairs, chains, or clusters during cell division, depending on their orientation and attachment. Many cocci bacteria do not have flagella and are non-motile, in contrast to many bacilli-shaped bacteria.
2- Single rod-shaped bacterium- Bacilli -A rod-shape bacterium or archaeon is a bacillus (plural bacilli), or bacilliform bacterium. In several different taxonomic classes, bacilli are found. Bacilli typically divide and are solitary in the same plane, but can combine to form diplobacilli, streptobacilli, and palisades.[2]
Diplobacilli: Two bacilli with each other arranged side by side.
Streptobacilli: Arranged bacilli in chains.
Coccobacillus: Coccus-like and oval (circular-shaped bacterium).
3- Cluster of round bacteria - Staphylococci - In the family Staphylococcaceae from the order Bacillales, Staphylococcus is a genus of Gram-positive bacteria. They appear spherical (cocci) under the microscope, and form into grape-like clusters. The species Staphylococcus are facultative anaerobic organisms (both aerobically and anaerobically capable of growth)
4- String of rod-shaped bacteria- Streptobacillus -Streptobacillus is a genus of fastidious gram-negative microaerophilic bacteria, an uncommon disease that develops in culture as rods in chains.t and can be caused by two forms of bacteria, Spirillum minus and Streptobacillus moniliformis.
5- Comma-shaped bacterium- Vibrio -Vibrio is a genus of Gram-negative bacteria with a curved-rod (comma) shape, which can cause foodborne infection in several animals, typically associated with consuming undercooked seafood. Vibrio species, usually found in salt water, are optional anaerobes that test positive for oxidase and do not form spores.
6- Corkscrew-shaped bacterium- Spirillium -Spirillum, a genus of spiral-shaped bacteria of the Spirillaceae family, aquatic with the exception of one species (S. minus) causing a form of human rat-bite fever. For any of the corkscrew-like animals, the name spirillum is used commonly.
Microbiologically, Spirillum is characterized as a gram-negative, motile helical cell with whiplike flagella tufts at each end.
hence, the images of the different bacteria are attached below-:

Which of those ancient populations is the most likely to have contributed significantly to the bottleneck effect in the YDNA variation observed across much of Eurasia?
1. Yamnaya
2. Denisovans
3. Basal Eurasians
4. Ancient North Eurasians
5. Gravettians
Answers
Answer:
The correct answer is "Yamnaya".
Explanation:
In genetics, a population or genetic bottleneck is defined as a reduction on the size of a population as a result of an environmental effect or human intervention. Regarding the Y chromosome bottleneck, the Yamnaya is an ancient population that contributed the most due to its sex-biased and stratified culture. The Yamnaya were violent and left behind many male skeletons, where just few type of persons were able to reproduce.

1. John is suffering from autosomal dominant deafness (D) and his wife Mary is normal.
Considering complete penetrance for this trait (P=1), what is the probability that this
couple's first child would have this disorder?
Answers
Answer:
Autosomal dominant inheritance: A person affected by an autosomal dominant disorder has a 50 percent chance of passing the mutated gene to each child. The chance that a child will not inherit the mutated gene is also 50 percent. However, in some cases an autosomal dominant disorder results from a new mutation that occurs during the formation of egg or sperm cells or early in embryonic development. In these cases, the child's parents are unaffected, but the child may pass on the condition to his or her own children.

What is the relationship between survivorship curves and reproductive strategies?
Answers
Answer:
Reproductive strategies are not an either/or sort of affair; some organisms fall somewhere between semelparity and iteroparity reproduction. In addition to various reproductive strategies, organisms differ in their survivorship strategies. Some organisms are at high risk of dying early in life, but if they can survive long enough, they have a decreasing probability of dying as the years go on. Well, to a point anyway. Other organisms have a steadily increasing probability of dying while still others live for a long time with the probability of dying only increasing dramatically after a certain (often old) age.

6. Many human and animal genetic disorders share similar characteristics
True

Answers
Answer:
1. False
2. True
3. False
4. False
5. False
6. True
Explanation:
1. Remember, the term Genetic diseases implies that they are diseases inherited genetically. Thus, environmental conditions have no direct influence on the spread of genetic diseases.
2. We can make this conclusion because research has shown that genetic disorders are more common in families with one affected member as compared to the general population. In other words, the family's medical history is part of the determinant factor.
3. Some recent studies have shown that both members of identical and fraternal twin pairs do not have the same likelihood of expressing the same genetic disease.
4. Genetic diseases do not occur at the same rate in all human populations. Researchers often make reference to findings discovered from surviving victims of the Hiroshima nuclear bomb which is said to be the cause of some genetic diseases. Also, the sickle cell genetic disease rate of occurrence is believed to be high in Africa than in North America.
5. Scientists believe that there is no specific age of onset of genetic disease. That is to say, they may appear within an age range but not a specific age.
6. Indeed, many human and animal genetic disorders share similar characteristics . A good example is the albino genetic order in humans has been discovered to share similar characteristics that is found in animals.
