why must both constricting and posionous snakes eat their prey alive?

Answers

Answer:

There is a very common misperception among people, even among many snake hobbyists, that snakes must have live prey.

Explanation:

This is not usually true. In the wild, snakes, like most other carnivores, will usually take any opportunity to get a free and easy meal, and will not pass up a freshly killed prey animal if they happen upon it. In fact, snakes have been known to eat a fair amount of carrion which has been dead for some time, and the stomach contents of wild snakes often contain prey that must have been in an advanced state of decomposition when it was eaten. Thus, although your snake may prefer to eat live prey, which it kills itself through constriction, this is not at all necessary for the health of the snake. In fact, it is best not to feed your captive snakes live prey at all.

Drag each tile to the correct location.
Identify each process as a carbon source or a carbon sink.

Answers

Photosynthesis, ocean absorption, and fossilization are carbon sinks. Combustion and respiration are carbon sources

Carbon sources are any natural or artificial production site of carbon and/or any chemical compounds composed of carbon, such as carbon dioxide and methane.

Carbon source: Combustion,Respiration.

A carbon sink absorbs carbon dioxide from the atmosphere.

Carbon sink: Photosyntheis,Ocean absorption,Fossilization.

Which one is carbon sink or carbon source?

1. Photosyntheis: Forests are typically carbon sinks, places that absorb more carbon than they release. They continually take carbon out of the atmosphere through the process of photosynthesis.

2. Ocean absorption: Phytoplankton are the main reason the ocean is one of the biggest carbon sinks. These microscopic marine algae and bacteria play a impotant role in carbon cycle - absorbing carbon.

3. Fossilization: Absorb CO2.

4. Combustion: Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives off heat and CO2 in environment.

5. Respiration:  The respiratory system, with its conduction and respiratory zones, brings air from the environment to the lungs and facilitates gas exchange both in the lungs and within the cells and gives out CO2 in atmosphere.

Thus, we can conclude that

carbon sink: Photosyntheis,Ocean absorption,Fossilization.

carbon source:Combustion,Respiration.

do DNA and RNA have the same phosphate group?

Answers

Answer: yes they do

Explanation: In a cell, a nucleotide about to be added to the end of a polynucleotide chain will bear a series of three phosphate groups. When the nucleotide joins the growing DNA or RNA chain, it loses two phosphate groups. So, in a chain of DNA or RNA, each nucleotide has just one phosphate group.

Which of the following is not a difference between photosynthesis and cellular respiration?

Answers

Answer: D

Explanation: They both play an important role in the carbon cycle. Photosynthesis removed CO2 from the atmosphere while cellular respiration causes the release of CO2 into the atmosphere.

The others are major differences

Photosynthesis has as its products Starch and O2 while those of cellular respiration are water , CO2 and energy.

The materials needed for photosynthesis are water and CO2 while those for cellular respiration are starch and O2

Photosynthesis occurs in chloroplast while respiration takes place in mitochondria .

Thus the only non- difference is D.

In a certain animal, it is possible to determine a dominant trait by crossing purebred lines and observing the proportion in offspring.

What are purebred lines?

The purebred lines are genetic lineages of organisms that are homo-zygous for a given genetic/phenotypic trait.

It is possible to determine the dominance level of phenotypic features by crossing purebred lines.

The proportion of the phenotypic traits in progeny will evidence the presence of dominace.

In conclusion, in a certain animal, it is possible to determine a dominant trait by crossing purebred lines.
