A punnet square predict the traits of offspring genetic crosses and test crosses.
<u>Explanation:</u>
In pea plants, the traits or characteristics inheritance is been observed and studies by Gregor Mendel. A model was proposed by him, in which the characteristics or traits are specified from genes. Genes can take different alleles or versions. The appearance of an organism can be determined by the dominant alleles. These hides the characteristics of recessive alleles.
The law of segregation is, When gametes are made by an organism the copy of one gene is passed to each gametes. The combinations of allele which is genotype, and the phenotypes which are the characteristics that are observable can be predicted by a Punnett square. This is done by genetic crosses.
In order to predict whether the organism is heterozygous or homozygous can be determined by a test crosses.
Answer: A chemical reaction is the change of a substance into a new one that has a different chemical identity. In summary, a chemical reaction is a process that converts one or more substances to another substance. Chemical reactions start with reactants and convert them into products. Most chemical reactions inside living things are regulated by enzymes, which speed up chemical reactions.A chemical reaction is a process that changes or transforms one type of chemical into another. ... Life is the result of countless reactions happening all at the same time, most often between carbon, hydrogen, nitrogen, and oxygen atoms. Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. ... A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
Explanation:
The potato crop devastation occurred in Ireland for not using one single potato species.
Explanation:
Potato became the staple crop of 18th Century Ireland and was easy to grow in the soil of this place. Later, it became the most dependent crop of the people of Ireland which made its supply very demanding leading to the yielding of more than one species of potatoes.
This yielding reduced the variety in the genetics of potatoes that helped in preventing the disease that affect potatoes by making the Irish people susceptible to famine. The Phytopthora bacteria affected the potatoes of North America in the year 1840 and Ireland’s moist weather in that same year made the blight to thrive.
Answer:
Surface currents affect climate by moving cold and warm water around the globe. In general, currents carry warm water from the tropics toward the poles and bring cold water back toward the equator. A surface current warms or cools the air above it, influencing the climate of the land near the coast.
Explanation:
I think the correct answer from the choices listed above is option A. The process that is being described above is called succession. Ecological succession is the process of change in species structure in a community as time goes by. Hope this answers the question.
