Answer:maintaining homeostasis

Explanation:

The process of maintenance of relatively constant internal i environment of an organism is called homeostasis.

Therefore the sudden change in the body temperature of the duck in water is adjusted by the deep con striction of the capillaries which retained heat to the internal body structures, and reducing convention to upper body surface , to maintain constant bidy temperature in respective of the change in the external temperature.

This is homeostasis.

It is a scientific law
Explanation:
A scientific law states a constant relationship between two or more variables, each of which represents a property or measurement of specific systems. It is a constant and unchanging rule, usually expressed mathematically which allows to predict the unknown based on what is known with logical and real relationships.
A scientific theory is a set of concepts and rules (scientific laws) that express the relationships between observations of such concepts and generates a principle or set of principles to explain a phenomenon.

In a monohybrid cross from heterozygous parents, of the offspring would be what genotypes? select all that apply.
Arada [10]

In a monohybrid cross with two heterozygous parents the result will be a genotypic ratio of 1:2:1 for homozygous dominant to heterozygous to homozygous recessive.  The phenotypic ratio will be 3:1 dominant trait to recessive trait.

In 1953, the scientists James Watson and Francis Crick published their landmark findings on the structure of DNA. Watson and Cri
Digiron [165]

Answer:

The correct selection of answers to the question: Identify the pieces of evidence describing the features of DNA that Watson and Crick used to determine the structure of DNA, would be:

C: The two chains are parallel, both running in a 5´ to 3´ direction

D: A purine base forms hydrogen bonds to pair with a pyrimidine base located on the opposite DNA strand. Specifically, A pairs with T, and C pairs with G.

E: The sugar-phosphate backbones of each DNA helix run antiparallel to one another

F: The diameter of the DNA doube helix is 2 nm, with each purine-pyrimidine base pair spanning an equivalent distance between the two chains.

Explanation:

Although Watson´s and Crick´s research, and model of the DNA helix, became the breakthrough for science, as it visually presented the now known characteristics of DNA, this research was possible due to the way that these two researchers used previous information found by other scientist on the molecule, to finally build their model. All of the options that were selected were part of the research of several scientis, including Mendel, Rosalin Franklin, Linus Pauling, Maurice Wilkins, Oswald Avery and many others, who worked on different aspects of specimens and their specific characteristics, and which led them to discover that organisms possessed DNA, that this was the unit of information that directed all functions in living cells and how this DNA helix was chemically built to understand how it worked, and why it worked the way it did.
