The lac operon genes, which encode vital enzymes for lactose absorption and processing, must be expressed for the bacteria to utilise lactose. E. coli should only express the lac operon when two conditions are met in order to be as effective as possible:
Glucose is not readily available, but lactose is.
The Y gene codes for lactose permease.
In the operon I- P+ O+ Z-Y+, I codes for repressor protein, therefore I- implies this lacks repressor means operon is not inhibited so it is always active.
Z codes for beta-galactosidase in this operon.
This haploid species can produce permease persistently but do not produce -galactosidase since this operon has no functioning Z gene but does have a functional Y gene.

How should the sperm motility be categorized in this microscopic field of a semen sample viewed at 400X magnification
The sperm motility can be categorized in this microscopic field of a semen sample viewed at 400X magnification - Non-Progressive motility = 2; immotile = 3
Fast and slow progressive motility are calculated from the speed at which sperm migrating the flagella migrate at a certain volume percentage (range 0% to 100%) by counting 200 sperm.
Decreased sperm motility may be a symptom of disorders associated with male accessory gland secretion and the sequential ejection of these glands.
Routine sperm analysis should contain at least 50% progressively motile class A and B sperm. Sperm viability should be checked if more than 50% of the sperm are fixed. Persistent reduced mobility is a good indicator of infertility and is actually the more important outcome when making decisions about treatment options for couples.

INTRO TO CELL RESPIRATION OVERVIEW POGIL: All cells need energy all the time, and their primary source of energy is ATP. The methods cells use to make ATP vary depending on the availability of oxygen and their biological make-up. In many cases the cells are in an oxygen-rich environment. For example, as you sit and read this sentence, you are breathing in oxygen, which is then carried throughout your body by red blood cells. But, some cells grow in environments without oxygen (yeast in wine-making or the bacteria that cause botulism in canned food), and occasionally animal cells must function without sufficient oxygen (as in running sprints). In this activity you will begin to look at the aerobic and anaerobic processes that are used by all organisms to produce ATP. Which statement is NOT true based on this intro
The products formed as a result of cellular respiration are ATP, water and carbon dioxide.
The cells require energy to perform all their cellular functions. The source of energy for them is ATP which is adenosine triphosphate. The amount of ATP which is produced by a cell depends on its requirement and also on the amount of oxygen that is available.
Depending on whether a particular organism requires oxygen or not, they can be classified as aerobic and anaerobic. Aerobic organisms are the ones which require oxygen whereas anaerobic organisms do not require oxygen. The reaction for cellular respiration can be represented as:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
Carbon dioxide, water and ATP are formed as products in this reaction.

what is the relationship of chemoreceptors, carbon dioxide, PH and ventilation rate?
The relationship between chemoreceptors, carbon dioxide, pH and ventilation rate is that the chemoreceptors detect changes in the levels of carbon dioxide and pH in the blood, and signal the brain to adjust the rate of ventilation accordingly to maintain the normal range of carbon dioxide and pH in the body.
What are chemoreceptors?Chemoreceptors are specialized sensory cells that detect changes in the levels of certain chemicals, such as carbon dioxide and pH, in the blood. These receptors are found in the carotid bodies and aortic bodies, which are located near the carotid artery and the aorta, respectively.
Chemoreceptors in the carotid and aortic bodies are sensitive to changes in the levels of carbon dioxide and pH, and they signal the brain to increase or decrease the rate of ventilation accordingly

what system works with the respiratory system to circulate blood and oxygen throughout the body
The cardiovascular system works with the respiratory system to circulate blood and oxygen throughout the body. The cardiovascular system includes the heart, blood vessels, and blood.
The cardiovascular system works in conjunction with the respiratory system to ensure that oxygen is delivered to the body's cells and that carbon dioxide is removed. When we breathe in, oxygen enters the lungs and is transferred to the blood, where it binds to hemoglobin. The oxygen-rich blood is then pumped by the heart to the body's cells, where it is used to produce energy. At the same time, respiratory system carbon dioxide, a waste product of cellular metabolism, is removed from the cells and carried cardiovascular system by the blood to the lungs, where it is exhaled. This process, known as respiratory system, is a continuous respiratory system cycle that ensures the body's cells receive the oxygen they need to function properly and that waste products are removed.

Blocks of genetic material that do not recombine and are passed on for generations are called
a) phenotypes b) genotypes c) karyotypes d) haplotypes
Blocks of genetic material that do not recombine and are passed on for generations are called haplotypes.
A haplotype is a set of DNA variants along a single chromosome that tend to be inherited together. Because they are close together on the chromosome and recombination between these variants is rare, they are usually inherited together.
The haplotypes represent sequences along the chromosome that are either conserved intact or separated over time by recombination. This basic concept has led to the development of methods to extract information about recombination to help researchers identify disease-causing genes and loci.
In the genome, alleles of closely spaced variants on the same chromosome tend to occur together more frequently than would be expected at random. These allelic blocks are called haplotypes.

What will happen to enzyme if active site loses its shape?
The substrate's affinity for binding will decline, causing the enzyme to either complete the reaction at a slower rate than usual or not at all, depending on how much the active site has changed.
Proteins known as enzymes serve as biological catalysts and speed up chemical reactions. Substrates are the substances that interact with enzymes, and the enzyme changes the substrates into products, which are other molecules. Enzyme catalysis is required for the bulk of cellular metabolic processes to proceed at speeds quick enough to support life. An enzyme is required for each step in the catalysis of metabolic processes. It is acknowledged in the fields of pseudoenzyme analysis, enzymeology, and the study of enzymes that some enzymes have evolved without the capacity to perform biological catalysis. Their strange "pseudocatalytic" abilities and amino acid sequences often reflect this.
