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.

answer: The global warming controversy concerns the public debate over whether global warming is occurring, how much has occurred in modern times, what has caused it, what its effects will be, whether any action can or should be taken to curb it, and if so what that action should be. In the scientific literature, there is a strong consensus that global surface temperatures have increased in recent decades and that the trend is caused by human-induced emissions of greenhouse gases.[1][2][3][4][5][6] No scientific body of national or international standing disagrees with this view,[7] though a few organizations with members in extractive industries hold non-committal positions,[8] and some have attempted to convince the public that climate change is not happening, or if the climate is changing it is not because of human influence,[9] attempting to sow doubt in the scientific consensus.

Answer: B. It sped up evolutionary change by increasing genetic variation.

Explanation:

Evolution works when organisms with genes that are better suited to the environment pass on their genes to future generations.

Sexual reproduction sped up this process because it allowed for genetic variation as genes from the two mates would be passed on the next generation instead of one organism as had been the case with asexual production.

With genes from both mates mixing up and going into the next generation, more genetic variations were produced which allowed for the organisms to better adapt to the environment.

Answer:

The correct answer is - overdominance.

Explanation:

In the given question, genotype Pp is a heterozygote condition that has a 54% survival rate or fitness thus these individual people get more chance of mating and increase in number as compared to the other two conditions of PP or pp traits where PP has 45% survivability, less than heterozygous condition and more than pp that has only 4% rate.

It results in a normalizing selection model of natural selection as a moderate trait, that is heterozygote, is selected. Thus, the selection of overdominance which means heterozygote condition produces a better phenotype than PP or pp parents is heterosis.

Answer:Like a brick wall, your body is composed of basic building blocks, and the building blocks of your body are cells.For example, epithelial cells protect the outside surface of the body as part of the skin and cover the organs and body cavities within.

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.

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:

- 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.

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.

Explanation:

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.

The steps by which surface water can become groundwater

B. Precipitation → zone of aeration → zone of saturation.

Groundwater is the reservoir of water this water accumulates in the ground surface or subsurface of the earth's crust through tiny pores and fractures in the rocks.
