<span>The correct answer is d: detached earlobes</span>

The phenotype is the result of genotype and its interaction with the environment. The phenotype is an observable characteristic of an organism's trait, such as its morphology. So, in this case, morphological characteristic of the earlobe is that it is detached.

Answer:

1. Cinder cones

2. All of these

Explanation:

1. Cinder cones develop from explosive eruptions of mafic (heavy, dark ferromagnesian) and intermediate lavas and are often found along the flanks of shield volcanoes. The outside of the cone is often inclined at about 30°, the angle of repose (the slope at which the loose cinder can stand in equilibrium).

2. Volcanic Explosivity Index (VEI) is a numeric scale that measures the relative explosivity of historic eruptions. Volume of products, eruption cloud height, and qualitative observations (using terms ranging from "gentle" to "mega-colossal") are used to determine the explosivity value. The Volcanic Explosivity Index (VEI) was derived to catalogue the explosive magnitude of historical eruptions, based on the order of magnitude of erupted mass, and gives a general indication as to the height the eruptive column reached.

Hope this helps!

The inherited genes in these chromosomes contain DNA sequences that are related to particular what?
kicyunya [14]
Scientists first discovered chromosomes in the nineteenth century, when they were gazing at cells through light microscopes. But how did they figure out what chromosomes do? And how did they link chromosomes — and the specific genes within them — to the concept of inheritance? After a long period of observational studies through microscopes, several experiments with fruit flies provided the first evidence.
What is a gene?

Physically, a gene is a segment (or segments) of a chromosome. Functionally, a gene can play many different roles within a cell. Today, most scientists agree that genes correspond to one or more DNA sequences that carry the coding information required to produce a specific protein, and that protein in turn carries out a particular function within the cell. Scientists also know that the DNA that makes up genes is packed into structures called chromosomes, and that somatic cells contain twice as many chromosomes as gametes (i.e., sperm and egg cells).

But what were the key scientific discoveries that helped establish these principles? As it turns out, the connections between genes, chromosomes, DNA, and heredity were not recognized until long after researchers caught their initial glimpse of chromosomes. The following sections present an abbreviated summary of the major discoveries that revealed these connections.

essa had $35. she bought a book for $7 and a magazine for $5. which expression correctly shows the total money tessa has left? a
Semmy [17]
<span>In both cases money is being taken away from her total amount. A negative negative is a positive, so you don't want any expression with a negative negative. This eliminates A, B, and D, leaving only C. In this expression, both times money is being taken away, making it correct.</span>
