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.

Herd behavior benefits wildebeests by (1 point)
O increasing the number of resources availablė.
O allowing altruistic behavior.
O decreasing the chance of spreading disease.
O helping individuals find mates.
Answer:
helping individuals find mates.
Explanation:
took test
The correct answer is option d helping individuals find mates.
We can begin the solution for this one with a method of elimination.
2 cannot be proper due to the fact herding conduct nearly definitely will increase the possibility of spreading diseases. For 3, having extra people in a set affects more opposition and consequently fewer assets so we are able to get rid of that one as well.Then the selection is among 1 & four. You ought to make a controversy for four however it appears a piece indistinct concerning the precise advantages of altruistic conduct. I'd argue that altruistic conduct is extra of an effect than a motive of sociality/herding.Choice 1 is a not unusual place reason for sociality in animals. In species that do not stay in social organizations trying to find buddies may be very high priced in phrases of time and electricity and publicity to predators. It's a whole lot less difficult to discover a mate while many people are residing in proximity. Because replica is this kind of essential a part of the existence cycle I consider 1 is the exceptional answer.What is herd behavior?Herd conduct is the conduct of people in a set appearing together without centralized direction. Herd conduct happens in animals in herds, packs, chook flocks, fish faculties, and so on, in addition to in humans.
Thus it is clear that the option that helps individuals find mates is the correct answer.

Good luck! ♡
The piece of evidence which would best support the argument for kin selection as a mechanism for the evolution of altruistic behavior is: A. a penguin protects its chick from seagulls.
Altruism can be defined as a phenomenon in which a living organism promote another organism's welfare, especially at its own detriment or disadvantage.
Hence, altruism is an act in which a living organism show selfness and concern for another organism's predicament, even at a risk or cost to itself.
In Evolutionary biology, a living organism is considered to be altruistic in nature, if its behavior is beneficial to other living organisms.
Based on kin selection, a living organism is considered to behave altruistically when its behavior is beneficial to organisms in its family or organisms that are directly related to it.
For example, a penguin which protects its chick (offspring) from seagulls best support the argument for kin selection as a mechanism for the evolution of altruistic behavior

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 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.

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.
