cladogram

Answers

Answer:

Cladogram.

Explanation:

A cladogram is a diagram used in cladistics to show relations among organisms. A cladogram uses lines that branch off in different directions ending at a clade, a group of organisms with a last common ancestor. In biology, taxonomy is the scientific study of naming, defining and classifying groups of biological organisms based on shared characteristics. Taxonomy would not be based on genetic diversion during evolution, it only describes similar characteristics amongst animals.

I also chose taxonomy on the test and it was wrong. The right answer said cladogram.

A specific type of model that shows how animals diverge during evolution is Cladogram. So, the correct option is D.

What do you mean by Evolution?

Evolution is defined as the process of growth and development or the theory that organisms have grown and developed from past organisms.

A cladogram is a diagram that shows the evolutionary relationships of several clades. A clade is a group of organisms, which contains both an ancestral species and its descendants. The common ancestor appears at the root of the cladogram.

Therefore, A specific type of model that shows how animals diverge during evolution is Cladogram.

High tides on points A & C occur when the moon, the Earth, and the Sun are all lined up.

SUN -----<<<  EARTH >>> ---

                                          ----MOON

( as accurate as it can be in 2D)

As you can see, they are all in a straight line. The gravity of both the moon and the Sun are combined to output the greatest amount of gravitational force as possible; creating high tides on the 2 sides of the Earth. Points A & C represent these two sides and are therefore the answer.

How does the attachment of spindle fibers differ between mitosis and meiosis I?

Answers

in mitosis, the spindle fibers start to divide. in meiosis, these fibers match back up again

In mitosis, the spindle fibers from two poles attach to each chromosome but in meiosis I, the spindle fibers from only ONE pole attaches to the chromosome.

WHAT IS MITOSIS AND MEIOSIS?

Mitosis and meiosis are two kinds of cell divisions. Mitosis involves separation of a single parent cell to produce two genetically identical cells while meiosis involves the separation of a single parent cell to produce four genetically different daughter cells.

WHAT IS SPINDLE FIBER?

Spindle fibers are structures that emanate from centrosome organelles and responsible for the separation of chromosomes during karyokinesis (nuclear division).

During the two cellular divisions (mitosis and meiosis), spindle fibers attach to the centromeres of each chromosome in order to align and eventually divide them.

However, in mitosis, spindle fibers from two opposite poles attach to each chromosome but in meiosis I, the spindle fibers from only ONE pole attaches to the chromosome.
