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

Answer:

540

Explanation:

In this case, the mutation rate from the allele black fur to the allele gray fur decreases by 10 percent per generation, while the original number of black fur alleles is 600.

Percentage of 10% of 600 = (10 x 600) / 100 = 60 alleles  

In consequence, the number of black alleles in the next generation will be >>> 600 - 60 = 540 alleles

Explanation:

wrote an essay on it

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.

Answer:

B

Explanation:

Or  - radiative zone, convection zone, core

Sun's atmosphere consists photosphere, chromosphere, and corona. Hence option d is correct.

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.

Explanation:

A hard tool and a hard surface combination most likely makes an indentation.

Drill cuttings may contain additional information about the mechanical characteristics of rocks, which has sparked research into indentation tests on cuttings-size samples.

These methods rely on casting the samples in a material that dries quickly (polyester, resin), which serves as a sample container and makes it easier to polish and grind the sample's surface.

The full load-displacement curve is typically recorded during these experiments, and the slope of the linear regime is utilized to correlate with mechanical characteristics of rocks like uniaxial compressive strength.

Therefore, A hard tool and a hard surface combination most likely makes an indentation.

Answer: What questions?

Explanation:

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.

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.

The correct answer is option d helping individuals find mates.

We can begin the solution for this one with a method of elimination.

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.
