the scottish fold is a breed of cat with a mutation in a gene involved in cartilage development. the result is that each ear of the cat has a crease, so the ears fall forward and lie against the head instead of standing up like the ears of most small cats. the mutation is a dominant allele.

a cat that is heterozygous for the fold allele mates with a cat that is homozygous for the fold allele.

what are the expected percents of offspring that will have each characteristic?

Answers

In complete dominance, the presence of at least one dominant allele in the genotype is enougth to express the dominant phenotype. 100% of the offspring will have mutated creased ear, while 0% of the will have normal standing ear.

What is complete dominance?

Complete dominance is the inheritance pattern in which the dominant allele completely masks the recessive allele.

This interaction between alleles is observed in individuals who are heterozygous for a particular gene. They carry both alleles but only express the dominant trait. The dominant allele is hiding the expression of the recessive allele.

In the exposed example,

E is the dominant allele and codes for the mutated creased ear,e is the recessive allele and codes for the normal standing ear.

Cross: a cat that is heterozygous with a cat that is homozygous for the fold allele.

________________ best summarizes how Durkheim's approach to religion differed from that taken by Wallace.

Answers

Answer:

Durkheim underscored the common, public, and all-encompassing nature of religion. It also speaks to the definitions that it embodies and how it causes people to emote.

Explanation:

Durkheim is a sociologist of french origins who believed that society was more powerful than the individual.  

This according to him, was so because society is held together by ideas that resonate across more than one individual. These ideas show up like norms, beliefs, and values which are subscribed to by many thus creating a collective consciousness. This collective consciousness makes it easy to predict how people generally are likely to behave either as a people or an individual.

Where would a new star most likely form?

Answers

Answer:

Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example of such as a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction.

Most galaxies have stars distributed throughout them that are born within dust clouds.

What are stars?

Any large, gaseous celestial body that is self-luminous and emits light as a result of its own internal energy sources is a star.

Stars are created when a very huge cloud of gas and dust in space slowly contracts under the force of gravity.

The presence of gas and dust clouds is relatively widespread, and our knowledge of the Milky Way Galaxy's star-forming regions is extensive.

Stars are born within dust clouds and are dispersed throughout the majority of galaxies. Most galaxies have stars distributed throughout them that are born within dust clouds.

The Orion Nebula is a well-known illustration of a dust cloud of this type.

Deep within these clouds, turbulence creates knots with enough mass for the gas and dust to start collapsing under its own gravitational pull.

Thus, this way, the stars are formed.

mention and explain four other farming activities ​

Answers

Answer:

Here are four other farming activities that are commonly practiced:

Irrigation: Irrigation is the process of providing water to crops when rainfall is insufficient or irregular. Irrigation systems can range from simple methods such as flooding fields, to more complex systems such as drip irrigation that deliver water directly to the roots of plants. Irrigation is particularly important in arid and semi-arid regions where water is scarce.

Fertilization: Fertilization involves adding nutrients to the soil to promote plant growth and increase crop yields. Common fertilizers include nitrogen, phosphorus, and potassium, which are essential for plant growth. Fertilizers can be applied in different forms, such as granules, liquids, or sprays, and can be organic or synthetic.

Pest control: Pest control involves the management of pests, such as insects, weeds, and rodents, that can damage crops and reduce yields. There are several methods of pest control, including chemical pesticides, biological control, and cultural practices such as crop rotation and intercropping.

Harvesting and post-harvest handling: Harvesting is the process of gathering crops from the fields, and post-harvest handling involves activities such as cleaning, sorting, and storing crops to maintain their quality and freshness. Post-harvest handling can also involve processing crops into products such as flour, oil, or juice, which can be sold or used for further processing.

Overall, these farming activities are crucial for ensuring the success of agricultural production and providing food and other products for human use. However, it is important to practice sustainable farming methods that minimize negative impacts on the environment and promote long-term productivity.

To digest or breakdown a carbohydrate what process needs to take place and what happens during that process?

Answers

Carbohydrate digestion begins in the mouth. The salivary glands in the mouth secrete saliva, which helps to moisten the food. The food is then chewed while the salivary glands also release the enzyme salivary amylase, which begins the process of breaking down the polysaccharides in the carbohydrate food.

#SPJ1

Starches and sugars are mechanically and chemically broken down into the single units glucose, fructose, and/or galactose during digestion. These single units are then absorbed into the blood stream and transported to be used as energy throughout the body.

What is carbohydrate metabolism?

The entire set of biochemical procedures involved in the metabolic synthesis, disintegration, and interconversion of carbs in living things is known as carbohydrate metabolism. Many vital metabolic pathways depend on carbohydrates.

Dietary glucose can either be processed through glycolysis or glycogenesis.

The resulting metabolic byproducts can either go on in carbohydrate metabolism to the citric acid cycle or return to glucose via gluconeogenesis or glycogenolysis, respectively.

Carbohydrates are broken down during digestion to produce ATP, a molecule that is high in energy.

The oxidation of glucose molecules results in the creation of ATP. To lower NAD+ and FAD, an electron is taken from a glucose molecule during oxidation.

Thus, this way, breakdown of a carbohydrate takes place.

List all the steps of Seafloor Spreading WITH Paleomagnetism combined. (Earth Science)

Answers

Scientists were persuaded by magnetic striping produced by paleomagnetism that mid-oceanic ridges were the sites of ongoing formation of new oceanic crust.

What are the steps that lead to seafloor spreading?Divergent plate boundaries cause seafloor spreading. The crust becomes more flexible and less dense when tectonic plates progressively drift apart due to heat from the mantle's convection currents. Less dense material rises, frequently creating a mountain or raised section of the seafloor. The crust finally breaks.The paleomagnetic poles must move with the continent because the paleomagnetic poles do not move relative to the continent because the magnetism of a rock is fixed into the rock at the moment of its formation. The continents move to their predrift positions with their respective paleomagnetic poles.A geologic phenomenon known as seafloor spreading occurs when massive tectonic plates—slabs of the Earth's lithosphere—split apart from one another.
