Describe how waves behave when they interact with a barrier or boundary.

Biology
1 answer:
Vladimir [108]3 years ago
5 0

It travels through the more dense medium until it reaches the boundary with a less dense medium. MIDDLE: At the boundary, both reflection and transmission occur. ... The reflected pulse becomes inverted when a wave in a less dense rope is heading towards a boundary with a more dense rope.

What is an enzyme and how does it work?
Yuliya22 [10]
All of the work being done in side of a cell is being done by enzymes. A bacterial like E.coli has about 1,000 enzymes floating in the cytoplasm at about any time. The purpose of a enzyme in a cell is to allow the cell to carry out any chemical reactions very quickly. the reactions allow the cell to build or take things apart as needed. This is how the cell grows and reproduces. Hopefully my answer helps a little!

please match the following nutritional types with the statements that most accurately describe them, to test your understanding
svetlana [45]

Autotroph: a creature that obtains its carbon from inorganic carbon dioxide

Chemotroph: an organism that obtains energy from chemical substances-Heterotroph: an organism that must receive its carbon in an organic form

Phototroph: an organism that produces energy from sunlight

The term "primary nutritional groups" refers to a category of creatures that are separated into subcategories based on the sources of carbon and energy that they require for survival, growth, and reproduction. Carbon can come from organic or inorganic sources, and energy can be derived from either light or chemical molecules. ATP, carbs, or proteins are used to store the liberated energy as potential energy. The energy is eventually put to use for activities essential to life, like movement, growth, and reproduction.

Let's suppose you were interested in developing drugs to prevent epigenetic changes that may contribute to cancer. What cellular
Vaselesa [24]

Answer:

Potential targets:

1- DNA methyltransferases

2- Chromatin modifiers such as histone acetyltransferases, histone deacetylases, histone methyltransferases, etc.

3- Components of the RNA interference (RNAi) machinery such as Dicer, Argonaute, etc.

Explanation:

Epigenetics can be defined as the study of any heritable change in the phenotype that does not involve modifications in the DNA sequence. Epigenetic mechanisms can be classified into three major types: 1-DNA methylation, 2-histone modifications (e.g., acetylation, methylation, phosphorylation, etc), and 3-regulatory non-coding RNAs (e.g., miRNAs, lncRNAs, siRNAs, etc) that modulate target gene expression via the RNA interference pathway. There are different types of proteins that are involved in these complex epigenetic mechanisms, and those cited above represent only some examples that can be used as therapeutic targets.

The process of _____________ is modeled in the plant cell diagrams seen here.
grigory [225]

<u>Answer:</u>

The process of "Osmosis" is modeled in the plant cell diagrams seen here.

<u>Explanation:</u>

Osmosis is the natural gross migration of solvent particles into a zone of higher solute concentration via a selectively permeable membrane, in the path that seeks to balance the amounts of solvents on both the ends. Osmosis as biological membranes are semipermeable, is a critical mechanism in biological systems.

Such membranes are usually impenetrable to massive and polar molecules like polysaccharides, ions and proteins while being porous to hydrophobic or non-polar molecules like lipids and to small molecules as carbon dioxide, oxygen, nitric oxides and nitrogen.
