Activity 12-5: A Dihybrid Punnett Square. Consider your answers in the previous question. In a separate piece of paper, solve the Punnett square for a cross between two heterozygous individuals (BbRr x BbRr); write the genotypes of the gametes along the top and the side of the square and fill in the squares.
Answers
Answer:
See the answer below
Explanation:
For each heterozygous parent with the genotype BbRr, the possible gametes are: BR, Br, bR, and br. A set of these gametes from one of the parents will be lined up along the top of the Punnet's square while another set from the other parent will be lined up along the side of the square.
The result is shown in the attached image.

in the fruit fly, the long wing allele is dominant over the short wing allele. What are the parental genotypes for a cross that yields 75% long winged offspring and 25% short winged offspring.
Answers
According to the scenario, the parental genotypes for a cross that yields 75% long-winged offspring and 25% short-winged offspring are Ll and Ll.
What are Genotypes?Genotypes may be defined as the ultimate combination of alleles of those genes which are significantly taken for specific studies.
According to the context of this question, in the fruit fly, the long-wing allele is dominant over the short-wing allele. This means that capital L is dominant over small l. So, the genotypes LL and Ll govern the dominant trait, i.e. Longwing.
The Punnett square for the given cross is as follows:
Therefore, the parental genotypes for a cross that yields 75% long-winged offspring and 25% short-winged offspring are Ll and Ll.

A client reports extremely frequent urination, sometimes urinating 10 to 12 times each day.
What fluid balance disorder would be expected with these symptoms?
Answers
Answer:
Lack of Antidiuretic hormone.
Explanation:
Antidiuretic hormone is a type of hormone which is responsible for controlling urination. It is produced in hypothalamus which is a part of a brain. Antidiuretic hormone is responsible to tell the kidney how much water in the body should be conserve to avoid dehydration. If less antidiuretic hormone is produced by the body so more urine is produced. Frequent urination is also occurs due to Diabetes insipidus. This disease produce more urination in order to control the concentration of glucose in the blood.

n your lab you are studying the genome of venomous rattlesnakes to find the gene which codes for their venom glands. You have two rattlesnakes, one rattlesnake has a mutation but can still produce venom. You compare his DNA to a normal rattlesnake. What type of mutation has occurred? Normal: AATCGCTACGCACGTCAG Mutated: TATCGCTACGCACGTCAG
Answers
Answer:
There are no options but the kind of mutation that occurred by carefully observing both sequences is:
POINT SUBSTITUTION MUTATION
Explanation:
Mutation is any change, whether small or big, in the nucleotide sequence of a gene (DNA). Mutation occurs from time to time in an organism either by a mistake during DNA replication or induced by a mutagen (mutation-causing substance). Mutation can be of different types depending on the effect on the mutant.
In this case of comparing the DNA sequence two rattle snakes, the sequences of the two snakes are:
Normal: AATCGCTACGCACGTCAG
Mutated: TATCGCTACGCACGTCAG
By carefully observing the two DNA sequences, one would realize that the only difference in the two sequences is the first nucleotide base. That is, in the normal sequence, th first base is Adenine (A) while in the mutated sequence, the first base is Thymine (T).
This type of mutation that involves only one nucleotide base is called POINT MUTATION. It can also be noticed that base "A" was changed "T". Hence, this is a type of SUBSTITUTION MUTATION because a single base was replaced by another in the sequence.

Discuss Connell and Slatyer three mechanisms of succession. Start your answer with a definition and an example of what is succession, and describe how succession begins.
Answers
Answer:
Facilitation, tolerance and inhibition models
Explanation:
J. H. Connell and R. O. Slatyer stated three different ecological succession models that explain how species composition may change by the effects of disturbances in the ecosystem. These models are as follow:
1- Tolerance model: in this model, the new species don't affect the growth and success of existing species, thereby the process of succession is purely associated with life-history strategies.
2- Facilitation model: only 'ideal traits' found in colonizing species lead to the initial succession. These ideal traits include for example effective mechanism of dispersal, water storage tissues to survive in dry regions, long-term seed dormancy, etc.
3-Inhibition model: Species that appeared during early succession are capable of inhibiting growth of species appeared in later stages, as well as reduce colonizing species abundance.
Using specific examples, discuss the roles of negative and positive feedback processes that maintain homeostasis.
Answers

Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points. In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.

A) cerebral cortex.
B) basal nuclei.
C) sensory pathways.
D) motor pathways.
E) All of the answers are correct.
The correct answer is E.
Explanation:
The cerebral cortex processes and filters its information before passing the most relevant aspects to other regions of the brain. Some of these brain regions, in turn, send information back to the cortex. These loops, known as 'feedback systems', are considered essential for the functioning of cortical networks and their adaptation to new sensory information. Neural circuits must first assess the importance of incoming sensory information and then refine how it is processed in the future. Positive feedback, triggered with the purpose of amplifying the response to the initial stimulus, can be compared to a chain reaction or a vicious circle. Few are the functions regulated by this mechanism; rather it is triggered in pathological situations. It is the system by means of which the organism very rarely regulates any of the bodily functions under normal conditions, making the initial stimulus to be maintained and even increased. This type of mechanism is predominantly present in pathological situations: Its constitutive elements are: stimulus, receptor, afferent pathway, integrating center, efferent pathway, effector and response. The response does not have the ability to satisfy the initial stimulus.

into a or become a seed in an enclosed hollow ovary. They are most diverse and largest group of animal kingdom.
Some angiosperms are autotrophs that uses carbondioxide, water and sunlight energy to produce their own food and releases oxygen.
Examples include maize, rice..
Some angiosperms are saprophytic which obtain energy from dead and decaying matter in the soil. They form a symbiotic relationship with fungi. Example is Neottia.
Some angiosperms are parasitic and they attach to their host through haustoria their by feeding on the host and causing harm on the host.
