Answer:

1. Cell Wall

2. Amount of Vacuoles

3. Plastids

4. Size

5. Plasmodesmata

Explanation:

1. Animal Cells dont have cell wall, while Plant Cells do.

2. Animal Cells contain many/ multiple vacuoles, while Plant Cells only contain one.

3. Animal Cells dont have plastids, Plant Cells do have (eg. Chloroplasts)

4. Animal Cells are larger in comparison to Plant Cells

5. Animal Cells dont have plasmodesmata while Plant Cells do have.

The graph shows the changes in the number of animal fauna's living on earth overtime in how the fauna's were affected by differe

eduard

Answer: C) The event at the end of the Triassic Resulted in the extinction of fewer fauna’s then in any other period

Explanation:

Looking at the graph, the event at the end of the Triassic resulted in the smallest dip in the amount of fauna in the graph. This means that this event resulted in the extinction of fewer faunas than any of the other five major events.

Option A is wrong as the event at the end of the Devonian decreased the number of Cambrian fauna.

Option B is wrong as the event at the end of the Cretaceous resulted in a decrease in the Paleozoic fauna.

Option D is wrong because the event that resulted in the Extinction of more fauna’s then in any other period was the event at the end of the Permian.

Explanation:

An example of homologous structures in vertebrates is

where the wings of bats, front flippers of whales, and forelegs of four-legged vertebrates like dogs and crocodiles are all derived from the same ancestral tetrapod structure.

A number of mutations have been described in the G protein Ras that have profound effects on its activity. For example, some mut

gladu [14]

Answer:

a mutation that blocks the GTPase activity of Ras

Explanation:

A G protein in inactive state is GDP bound but as soon as a guanine exchange factor (GEF) exchanges it with GTP it gets activated which means that in GTP bound state it is active. G - protein has endogenous GTPase activity. Upon interaction of GAP, the GTPase activity of this protein is exhibited. When GAP is present, hydrolysis of GTP into GDP occurs which leads to inactivation of G protein. A mutation which will block GTPase activity of Ras will therefore result in constitutive active signaling even in the absence of ligand binding to it's receptor. In such scenario, GTP will not be hydrolyzed into GDP so signaling will be up-regulated.
