ANEK [815]3 years ago

Out of the following given choice;

F.  replaces the animal's soft tissues.

G.  enters the animal's body cavity.

H.  hardens before the animal decays.

J.  mineralizes the animal's bones.

The answer H. This can be caused by hot pyroclastic flows or falling volcanic ash from the atmosphere following a volcanic eruption. The ash buries animals and plants intact without moving them and without completely crushing or burning them. Over time excess silica dissolved in the water often replaces soft bone materials molecule by molecule, creating an almost indestructible fossil (like petrified wood) that lasts for millions of years

Answer:

It would be A: a cell that has double the number of chromosomes as the parent cell

and if for some reason that is wrong then it could possibly be C and just use the same explanation.

Explanation:

This is because Haploid Gametes are the things that are produced during meiosis-which is a type of cell division which reduces the number of chromosomes in a parent diploid cell by half

What property of a hormone would allow it to pass unassisted through a plasma membrane?
siniylev [52]

Ans.

Hormones are regulatory substances synthesized by various plants and animals and play role in proper growth, development, and maintain homeostasis. Hormones are released by signalling cells and show their actions after binding to specific receptors present on the surface or inside of the target cell.

Hormones, for which receptors are present inside the cells (in cytosol or nucleus) should be hydrophobic in nature. This is because plasma membrane is made up lipid molecules and small, hydrophobic, uncharged molecules can easily pass through this. For example, cortisol, estrogen, and progesterone hormones are lipid-derivatives and receptors for these hormones are present inside the cells.

"ricin inhibits the functioning of ribosomes. What part of protein synthesis would be affected by ricin? What effect would this
kondor19780726 [428]

Ricin comes under the category of functionally related toxins, in a combination known as RIPs (ribosome inactivating proteins). This disables ribosomes and stops the process of protein synthesis.  

They directly associate with and inactivate the ribosomes or modify the factors taking part in the process of translation, generally the elongation step. These proteins bring about depurination of adenine at position 4324 in the 28 S rRNA.  

This further inhibits the generation of a critical-stem-loop configuration to which the elongation factor is considered to combine at the time of the translocation step of translation. The ultimate outcome of this activity is the complete inhibition of cellular translation.
