Currently, two extant elephant species (X and Y) are placed in the genus Loxodonta, and a third species (Z) is placed in the gen

us Elephas. Thus, which statement should be true?
Species X and Y are not related to species Z.
A) Species X and Y share a greater number of homologies with each other than either does with species Z.
B) Species X and Y share a common ancestor that is still extant (in other words, not yet extinct).
C) Species X and Y are the result of artificial selection from an ancestral species Z.
D) Species X, Y, and Z share a common ancestor, but nothing more can be claimed than this

Answer:

A. Species X and Y share a greater number of homologies with each other than either does with species Z.

Explanation:

In taxonomy,  living organisms are placed into groups according to their similarities.

Genus is a classification group above of species. It consists of species that are closely related.

For the species X and Y to be placed in the same genus, they must be sharing a greater number of similarities or homologies compared to species Z.

Species Z does not have greater similarity with either Species X or species Y

Explain how famine, disease, and war are more likely with larger populations.​
Iteru [2.4K]
Famine- High population means more mouths to feed
Disease- Diseases usually spread more quickly with people who live closer( as it can just move from one person to the other)
War- People like to fight for land, resources, money, etc. And having more of those things mean they are more able to support families, communities, and more.

(Hope this helps a little)

Assignment Summary For this assignment, you will model the structures of the cell and describe their functions. You will do this
iren [92.7K]

The model of the structures of the cell and and their functions is given in the image attached.

<h3>What are the cell structure and their functions?</h3>

Some explanation on structure of cells is given below:

The nucleus:

This is known to be the  key or major organelle that tends to sustain or hold the genetic information that is needed  for reproduction and cell growth as well as development.

Note that  all cell is known to be made up of one nucleus and also a kind of membrane-bound organelles that can be seen in the cytoplasm.

Mitochondria:

This is known to be a double membrane-bound organelle that is known to function by acting as the site for the energy transactions and it is made for the survival of all cell.

Therefore, The model of the structures of the cell and and their functions is given in the image attached.

Suppose that in another world, DNA does not undergo semiconservative replication, but instead a conservative mechanism is used.
Liono4ka [1.6K]

Answer:

c. ¼ heavy, ¾ light

Explanation:

DNA replication follows semi conservative model which means that both the strands separate during replication and the newly formed DNA molecule has one old and one new strand. If instead of semi conservative, conservative mechanism is used, old strands will not separate from each other and the two newly synthesised DNA strands will come together to form a DNA molecule.

Here the cells were first grown in heavy 15N medium so all the DNA molecules had 15N and thus were heavy. Then the cells were transferred to 14N medium where only lighter 14N were available for replication process.

In first generation, 14N DNA molecules were synthesised from 15N DNA molecules so 1/2 DNA molecules were 15N and other half were 14N. In the second generation, 14N molecules will give rise to new 14N molecules and 15N molecules will also give rise to 14N molecules hence 1/4 molecules will be 15N (heavy) and 3/4 will be 14N (light).
