Explain how a mutation in a bacterial cell could help it become resistant to infection by a bacteriophage
zhenek [66]

Bacteria have different phage resistance mechanisms, such as spontaneous mutations, the CRISPR-Cas system.

Spontaneous mutations are the main mechanisms leading to phage resistance by altering the structure of bacterial wall components that act as phage receptors. These include lipopolysaccharides (LPS), outer membrane proteins, cell wall teichoic acids, capsules, and other bacterial components.

How do you think the rock layers and fossils found in Red Rock Canyon can provide evidence for Earth's geologic history?
Bogdan [553]

Answer and Explanation:

Red Rock Canyon is an area of universal geologic interest, located a few miles west of Las Vegas within the Mojave Desert. Many experienced geologists visit the Red Rock; they are surprised by the vivid colors of rocks, natural beauty, and rock formations. A visual display takes million years to make the masterpiece known as the Red Rock Canyon National Conservation area. About 500 million years ago, Red Rock Canyon was found at the bottom of an ocean basin. Limestone accumulated in this ocean basin, which contains the fossils of sea life. The tracks of two-footed meat-eating dinosaurs have been found in the Aztec Sandstone. The tracks of small animals such as spiders, scorpions, early mammals, and proto-mammals were also found. The fossils and rock layers that are found in Red Rock Canyon provide evidence for Earth’s geologic history.  Paleontologists are still searching these areas.

What are the four carbon macromolecules the body uses and makes?
aliya0001 [1]

Living things are made of types of molecules, known as macromolecules.

There are four major classes of biological macromolecules:

carbohydrates

lipids

proteins

nucleic acids

Each of these types of macromolecules performs a wide array of important functions within the cell; a cell cannot perform its role within the body without many different types of these crucial molecules. In combination, these biological macromolecules make up the majority of a cell’s dry mass. (Water molecules make up the majority of a cell’s total mass.) All the molecules both inside and outside of cells are situated in a water-based (i.e., aqueous) environment, and all the reactions of biological systems are occurring in that same environment.
