When you pushed the diaphragm up what change occurred in chest cavity pressure? Explain how this change in chest cavity pressure affected the lungs.
Answer:
positive pressure
Explanation:
Exhalation is a passive process during which the intercostal muscles and the diaphragm relax. The ribs move downward and inward, while the diaphragm rises. This movement causes the chest to decrease in size and positive pressure to build inside the chest cavity. The positive pressure pushes air out of the lungs.
Choose the true statements about the evolution of complex characters, such as powered flight.
a. The intermediate stages in the evolution of a complex character had no fitness advantage.
b. Often the initial stage in the evolution of a complex character was an adaptation to some unrelated selection pressure.
c. Usually a single mutation in one gene leads to the simultaneous appearance of the complex character.
d. Phylogenetic analysis using cladistics can help reveal the sequence leading to the evolution of a complex character.
e. Usually a single mutation in one gene leads to the simultaneous appearance of the complex character.
Answer:
b. Often the initial stage in the evolution of a complex character was an adaptation to some unrelated selection pressure.
d. Phylogenetic analysis using cladistics can help reveal the sequence leading to the evolution of a complex character.
Explanation:
The evolutionary developmental program of complex characters can be analyzed by examining synapomorphies, i.e., by examining shared, derived characters common between an ancestor of a given taxonomic group and its descendants. Synapomorphies are able to create evidence for historical relationships between closely related organisms. Moreover, cladistics is a method used to categorize species/taxa into groups called 'clades' based on arranging organisms with similar traits, which can provide useful information on the evolutionary history of complex traits in different species/taxa. In phylogenetics, the analysis of complex characters involves two different stages: 1-character analysis and 2-cladistic analysis. Homology refers to structures that look similar because they were inherited from a common ancestor (i.e., they have a common origin); whereas characters are considered as parts of transformation series. In cladistics, characters used for inferring phylogenetic relationships are considered as hypotheses of homology that are subject to tests of similarity. In consequence, such characters can provide useful information on the evolutionary history of complex traits.

B. Mutations in sex cells are chromosomal mutations.
О O
C. Mutations in sex cells are more deadly.
О O
D. Mutations in sex cells are silent mutations.
SUBMIT
Answer:
A.
Explanation:
Mutations that happen in sex cells during meiosis are able to pass onto offspring.
"Mutations in sex cells can be passed on to children." Therefore, option (A) is correct.
What is mutation?A mutation in a sex cell differs from a mutation in a non-sex cell in that mutations in sex cells can be passed on to children. Sex cells, such as eggs and sperm, carry genetic information that is passed on to the next generation during fertilization.
If a mutation occurs in a sex cell, it can be transmitted to the offspring and can potentially affect the genetic makeup of future generations. On the other hand, mutations in non-sex cells, such as skin cells or liver cells, cannot be passed on to offspring because they do not contribute to the genetic material of the next generation.

It was found that the C4 protein promotes synaptic pruning during brain development in the teenage years. This is a normal process in brain development that is important for removing unnecessary connections between neurons and establishing a mature brain structure. However, high expression levels of a certain allele of C4 can lead to too much pruning, which may promote the onset of schizophrenia. The variation observed at the C4 gene which leads to the greatest increase in risk was found to cause a 25% increase in the risk of developing schizophrenia. The baseline risk in the population is 1%. What is the risk of an individual with this variant developing the condition?a. 0.25%.
b. 1.25%.
c. 25%.
d. 26%.
Answer:
b. 1.25%
Explanation:
Variations observed in C gene has increase in risk of 25% to develop schizophrenia. It is a kind of an abnormality in which a person interprets reality unrepresentative. The baseline risk in population is 1% then there is 1.25% risk associated with an individual to develop this condition.

Assignment 1 - Provide a narrative for the following scenarios. Use complete
sentences and be careful with spelling and grammar. 20 Points (5 points each)
1. The physician orders urine C&S on a patient. The patient asks why it is
necessary to do this test. How would you, the medical assistant, clearly
explain this to the patient?
2. A patient is asked to bring in a first morning urine specimen for testing.
You, the medical assistant, provide the patient with a container for the
collection and explain that it needs to be refrigerated if they cannot bring
it to the office right away. How do you explain to the patient the need
for a first morning specimen and the request to refrigerate?
3. A patient is being treated for diabetes. This patient asks you, the
medical assistant, why it is necessary a urine specimen is collected each
Answer:
1.Urine culture and sensitive is used to identify the microorganism that is causing the infection, and to identify the antibiotics, sensitive to the microorganism, if the urinary tract is not treated promptly it can lead to recurrent urinary tract infection.
2. First urine sample of the morning is more concentrated form as urine is present in the bladder for almost 8 hours. It contains an increased number of protein or urinary casts. The sample is placed in the refrigerator to get refrigerated as holding it at room temperature and if infected with bacteria present in the urine it uses the glucose and alter the results.
3. diabetic ketoacidosis is one of the many complications if you are having diabetes. Another complication is diabetic nephropathy inorder to check the urine acetone as well as protein in urine we advise for urinalysis each time you visit.
Why do you think type 2 diabetes occurs so much more often than other inheritable diseases? Propose a hypothesis for why this allele has not been eliminated by natural selection.
Which type of species best describes a mouse: opportunistic or equilibrium? Explain why a mouse or rat population would continuously grow while other mammals (cheetahs) are nearly extinct.
Answer:
This allele has not been eliminated by natural selection because it may confer an adaptive advantage for particular environmental conditions
Mice and rats are opportunistic species. These species can rapidly adapt to different environmental conditions, while cheetahs are unable to adapt to changing environments.
Explanation:
An allele is a gene variant that may be beneficial, neutral, or deleterious for a particular environment. Different alleles are not eliminated by natural selection against other alleles (even when a priori seem to be deleterious) because they confer a selective advantage in a given environment. For example, the allele for sickle cell anemia is caused by a point mutation which is lethal in homo-zygous individuals, but heterozygous individuals are less likely to die of malaria, thereby this allele has been positively selected in geographic areas where malaria is an endemic disease. Moreover, mice and rats are opportunistic species, i.e., they are species that rapidly adapt to varied living conditions. These species are characterized to have high growth rates and produce many offspring. On the other hand, the cheetah is a highly specialized species that is unable to adapt to changing environments. In consequence, cheetah populations are more prone to become extinct than rat and mice populations.
Discuss who is impacted by desertification including which continents are impacted and the role of an increasing population.
Answer:
Africa and Asia.
Explanation:
Africa and Asia are the most affected regions in the world which is greatly affected by desertification. The climate change and human activities has a great impact in these areas which causes desertification as compared to other areas in the world. The increase in population increase the rate of depletion of natural resources which causes more pollution in the environment that leads to desertification in these areas.

What is the probability that a hybrid individual with the genotype AabbCcddEeFf will produce a gamete that has the genotype abCdeF
Answer:
6.25%
Explanation:
Find the number of different gametes that can be produced
number of gametes produced = 2^n
n is the number of allele pairs that are heterozygous
there are 4 heterozygous allele pairs, these are: Aa, Cc, Ee and Ff
2^4 = 16
abCdeF is one of the 16 genotypes that could be produced
to find the percentage, divide 1 and 16 and multiply by 100
1 ÷ 16 = 0.0625
0.0625 × 100 = 6.25
