<h3><u>Layers that form in ice are similar to tree rings:</u></h3>
  • Dendrochronology is the term for the study of tree rings. It counts the 'number of rings' in a tree and studies it.
  • A ring represents a specific period of time, similar to 'tree rings layers' of ice also provide information such as climate from past environmental conditions by the air bubbles that is  trapped in it.
  • Both the ice and the tree rings tell us about the past information.

Answer:

<h3>Each layer found in ice represents one year of snow fall. Each tree ring represents one year of growth. Both ice layers and tree rings, based on their size and make up, can tell us about the climate for that given year.</h3>

musickatia [10]

The observed distribution of alleles into gametes is an illustration of Mendel’s law of segregation and independent assortment.

Mendel's law of independent assortment - the alleles a gamete receives get sorted into gametes independently of one another (one gene does not influence the allele received for another gene).

Mendel’s law of segregation -  each gamete receives one gene copy selected randomly.

scalloped (sd) is an X-linked recessive and ebony (e) is an autosomal recessive mutation. What proportion of scalloped, ebony fe
alisha [4.7K]

Answer:

1/16

Explanation:

  • scalloped (Xsd) is an X-linked recessive trait to Xsd+ (wild type)
  • ebony (e) is an autosomal mutation recessive to e+ (wild type).

The two genes are independent because they are located on different chromosomes.

<h3><u>Parental generation:</u></h3>

True breeding scalloped female wild type for ebony (<em>Xsd Xsd e+e+</em>) mates with a true breeding male mutant only for ebony (<em>Xsd+ Y ee</em>).

The female only produces <em>Xsd e+</em> gametes. The male produces <em>Xsd+ e</em> or <em>Y e</em> gametes.<u> Therefore, the F1 females will have the genotype </u><u><em>Xsd Xsd+ e e+ </em></u><u>and the F1 males will have the genotype </u><u><em>Xsd Y e e+.</em></u>

If you complete a Punnett Square with the gametes the two F1 individuals can produce, you will get all the F2 proportions. The scalloped, ebony females have a<em> Xsd Xsd e e</em> genotype and appear in a 1/16 proportion.

Methodology for Studying Evolution:
Over [174]
The fossil record is important for evolution because they show that life from the past is different from life today. Scientists, such as paleontologists can determine the age of fossils by using technology provided today; known as radiometric dating, to sort them and determine relationships with organisms today. It allows us to get a whole view on the possible relations of today.

Homologous Anatomical Structures provide such a big support to the thought of evolution as well. They are structures that are similar in some organisms because they were inherited from a common ancestor. The functions may or may not have been used by the past ancestors, either. This supports evolution widely due to us seeing what we've evolved from, and what animals have evolved from. It allows us to determine ancestors as well. 

Embryology is a very good one, looking at the early stages of animal development. This allows scientists learn about how different species have evolved over time. It supports evolution largely due to this. A very good branch of science, spreading the thought of evolution each and everyday.

Apologies- I don't have an answer for the other explanations.
