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.

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.

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.

Although Myriapods share many characteristics with other arthropods, they distinguish for having an elongated and multisegmented body, one or two pairs of legs per segment, two antennae, and rolling-up ability

----------------------------------------  

As the name refers to, Myriapods have many feet. They characterize because their bodies are very elongated and divided into multiple segments. From each of the rings, emerge one or two pairs of legs.

As every arthropod, their bodies are segmented and covered by a cuticle for protection and to avoid dehydration.

Their heads carry two antennae, ocellus, and a mouth with prominent buccal appendixes. Some of them might be poisonous.

They can be slow when moving, but they are well-adapted to move through leaves and other organic material. But because they move slowly, they need a protection strategy to avoid predation. This strategy is rolling. They can roll up, and remaining like a boll, until the predator leaves.

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

Answer:

Cultivation of crops and tillage practices.

Explanation:

Farming of crops and tillage practices on the grasslands depleted grassland that are present across North America because the lands are converted and used for the production of food crops in order to fulfill the feed the existing population. More and more land is converted from grassland to the cultivation of crops that leads to lower area for the grazing of animals which results in decrease population of animals such as sheep, goat and cow etc which depends n these grazing regions for food.

is it the growth or?

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.

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.
