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

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.

two models of sells are shown below. Why would model b be better for moving nutrients in and out of the cell?
Answer:
The correct answer is - C. It has a larger ratio of surface area to volume.
Explanation:
In cell B, the ratio of surface area to volume is larger in comparison to cell A. The surface area to volume ratio can be understood as it is the size of surface area that the volume of a particular substance can move in or out of the cell, in a unit of time.
Thus the larger the ratio of surface area to volume faster the diffusion rate of nutrients will be as the surface area is a square measurement and volume is cubed so the surface area increases faster than volume.

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.

state three features of myriapods that can be used to distinguish them from other arthropods
Answer:
Mandibles (lower jaw) and maxillae (upper jaw)
Two body sections (head and trunk)
One pair of antennae on the head
Explanation:
hope this helps! have a great day / night
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.

What farming practices have depleted grasslands in North America?
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.
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.
