6.The development of antibiotic-resistant M. leprae is inevitable. Researchers are trying to develop antibiotics that would inhibit the biosynthesis of mycolic acids. Would this type of antibiotic be useful to treat M. leprae infections
Answer:
explanation below
Explanation:
Leprosy, known as Hansen’s disease, is a chronic infection that is caused by Mycobacterium leprae. This disease damages peripheral nerves and effect areas like skin, yes, muscles and noses. Antibiotics are used to treat the infection between 6 – 12 months. When infected people refuse to follow the treatment schedules given to them by the medical experts, there is usually the development of more antibiotic-resistant M. leprae.
M. leprae, just like tuberculosis, cell walls contain fatty molecules known as mycolic acids, which make the bacteria less susceptible to antibiotics.
Researchers have made remarkable progress in developing drugs such as ethionamide, isoxyl, thiolactomycin, and triclosan that are known to inhibit mycolic acid biosynthesis.
The development of these drugs are part of the tuberculosis drug discovery efforts (in the last one decade) which has been successfully applied to therapeutic targets in the unique mycobacterial wall.
Since morphology and cell wall of M. leprae does not differ remarkably from that of M. tuberculosis, antibiotic developed to inhibit the biosynthesis of mycolic acids would help to treat leprosy

Which of the following functions in multicellular organisms is similar to the function of DNA in unicellular organisms?
A.
Inheritance of traits
B.
Cell respiration
C.
Cell digestion
D.
Protein synthesis
A. Inheritance of traits
Both single and multi-celled organisms embrace a functional unit of life, known as “Cells”. Both of them consist of plasma membrane and cytoplasm. They carry similar features by containing DNA and ribosomes for the gene expression. All known forms of life store their genetic information using DNA, and with a few exceptions the code is universal.Both have basic unit of life (cell). Which means they both ingest food ,respire, and get rid of waste.Multicellular organisms are bigger than unicellular organisms. Unicellular has a single cell but multicellular have more than one cell.Thus, option A is correct.

Soooo... anyone have an essay on the impact of climate change on the oceans they’d like to share?? :)
I need ideas!!!
Answer:
Here's a paragraph that you can add !
Explanation:
When greenhouse gases capture more solar radiation, the oceans consume more heat, resulting in higher sea surface temperatures and increasing sea level. Changes in water temperatures and tides caused by climate change will cause changes in global climate patterns.

which three layers of the sun make up the suns atmosphere
a - plasma, corona, convection zone
b - radiative zone, convection zone, core
c - core, convection zone, chromosphere
d - photosphere, chromosphere, corona
Answer:
B
Explanation:
Or - radiative zone, convection zone, core
Sun's atmosphere consists photosphere, chromosphere, and corona. Hence option d is correct.
What are the three layers of the suns atmosphere?Sun is divided into two parts internal sun and atmosphere. In sun's atmosphere, it consists photosphere- the visible surface of the sun,
chromosphere- it is the transition state between the photosphere and corona.
The outermost hot shell of the atmosphere is the corona, these there layers males the sun's atmosphere.
These three layers make the sun's atmosphere apart from its internal structure, core, radiation zone, and convection zone these are three interior layers of the sun.
Therefore option d corona, chromosphere, and photosphere are correct.

Answer: What questions?
Explanation:
What assertion can be made about the corpus luteum that is altered upon implantation of the developing embryo
Answer:
alteration of the corpus luteum results in early pregnancy loss (early embryonic death)
Explanation:
The corpus luteum is a temporary gland structure in the female reproductive system (formed in the ovary that released its ovum), which is involved in the secretion of progesterone hormone and also moderate levels of other hormones, i.e., estradiol and inhibin A. After 7-10 weeks of gestation, this structure (corpus luteum) is replaced by the placenta that produces progesterone throughout the rest of the pregnancy. Normal progesterone levels (i.e., between 10 and 20 ng/ml) are required prior to embryo implantation, thereby alteration of the corpus luteum function will lead to disturbance of maternal recognition of pregnancy because pregnancy does not occur until the fertilized egg implants into the uterus.

What is thedifference between
Individual offspring genotype
Total genotype for the offspring
Answer:
A genotype is an individual's collection of genes. The term also can refer to the two alleles inherited for a particular gene. The genotype is expressed when the information encoded in the genes' DNA is used to make protein and RNA molecules.
Genotype is also used to refer to the pair of alleles present at a single locus. With alleles 'A' and 'a' there are three possible genotypes AA, Aa and aa. With three alleles 1, 2, 3 there are six possible genotypes: 11, 12, 13, 22, 23, 33.
Answer:
total genotype is for the entire genes of the offspring individual offspring genotype is of a certain set of genes for 1 parent
Explanation:
Design an experiment to test the role of thyroxine in helping the body adjust to cold temperatures. Describe the overall investigation to be done, the variables to be changed, the variables to be kept constant, the subjects to be used, the control and experimental conditions to be used, the type of data collected, and how the data will be collected. Explain how these data can be used to justify the conclusion that thyroxine is involved in adjusting body temperature in response to cold. (9 points)
Answer:
- Hypothesis: thyroxine gene is responsive to low temperatures, thereby its transcript level is higher in cold climates
- Subjects of study: gene expression data collected from individuals from countries with different climates
- Experiment: to determine thyroxin gene expression level by Real-Time PCR (RT-PCR) in individuals living in cold climates (e.g., Iceland) versus individuals living in warmer climates (e.g., Puerto Rico)
- Independent variable: temperature
- Dependent variable: thyroxin transcript level
- N sample: 500 individuals of each population
- Control group: individuals living in the same climate conditions but from different countries. It can be done by collecting gene expression data from individuals living in another country. For example, both Fairbanks (Alaska) in the USA and Reykjavik in Iceland are at 64 degrees N latitude, and thereby these cities have similar climates
- Constant variable: all data collected from individuals of adult age (age range: 20-30 years)
Explanation:
The scientific method is a sequential process that consists of making hypotheses in order to explain observations from the real world, make predictions based on the working hypotheses, carrying out experiments based on those predictions, test the predictions and draw conclusions based on the results obtained. In an experiment, the independent variable isn't changed by the other variables, while the dependent variable is the variable being measured in the experiment. A constant variable does not change during the experiment. Moreover, a control group is a particular group to which comparisons are made during the experiment (the control group isn't exposed to the independent variable, and therefore any change in the experimental groups can be compared with the control). In this case, it is expected to measure thyroxine expression levels in 500 individuals from each country by RT-PCR (RT-PCR technique is used to measure the amount of mRNA of a target gene of interest). Subsequently, it is possible to determine if the differences in the thyroxin gene expression levels between populations (i.e., individuals living in Iceland vs individuals living in Puerto Rico) are statistically significant to confirm that thyroxin gene activity is increased in response to cold exposure. Finally, the control group can be used to determine if observed differences in gene expression are irrefutably correlated with cold conditions.

A scientist wants to determine whether a mutant phenotype is due to the loss of gene C or gene D, which are both deleted in a mutant fly with abnormal eyes. Mutant flies with that have a transgenic gene C have wild-type eyes, whereas mutant flies that have a transgenic gene D have abnormal eyes. What can be concluded from these results
Answer:
a transgenic copy of the gene C is sufficient to restore normal eye development
Explanation:
In genetics, there are diverse approaches to determining a gene's function. For example, it is possible to use a complementation test to determine loss-of-function recessive mutations when it is unknown if such mutations fall in the same or in different genes. Similarly to the generation of loss-of-function phenotypes, it is possible to insert a gene and thus produce a gain-of-function mutation that restores normal gene function (i.e., to restore the wild phenotype). Moreover, transgenic organisms refer to genetic engineering techniques by which any foreign or modified gene is inserted in the genome of an organism, which can also be used to study gene function. In this case, the restoration of the normal phenotype (wild-type eyes) is associated with the expression of the transgenic gene C, thereby evidencing that the gene C is required for normal eye development. In the last years, transgenic models have shed light on developmental pathways and on gene function.
