Name the four things that can happen to move carbon from a plant and return it to the atmosphere
kvv77 [185]

1. Respiration-process by which plants release CO, while they break down the sugar

2. Animals eat plants- They break down sugars and starches by a process of metabolism and the products are energy water, and CO2 molecules.

3. Decomposition-when plants die, their parts (wood, leaves) decay bringing the carbon into the ground

4. Root respiration- respiration that occurs in roots, adds to soil respiration (the amount of CO2 produced through root respiration is determined by the root biomass ).

A green seed it can you plant in the yellow seeded P plant half offspring with all yellow seeds what is the most likely reason
Alina [70]

Answer:

In cross-pollinating plants that either produce yellow or green pea seeds exclusively, Mendel found that the first offspring generation (f1) always has yellow seeds. ... that a trait may not show up in an individual but can still be passed on to the next generation.

Secondary structure is determined by interactions between amino acid side chains and tertiary structure is determined by interac
STatiana [176]

Answer:

False

Explanation:

The sequence of amino acids in a protein is determined by the DNA and the structure of protein thus formed is a linear sequence.  These linear structures undergo structural changes due to the formation of bonds between the constituent molecules.  

When bonds are formed by the interactions between the CO group of one chain and the -H group which forms the backbone is known as the secondary structures. Two types of arrangements arise of this that is the helical and pleated sheet.

When the bonds are formed between the side groups or the R group of the amino acid therefore the amino acid structure formed is known as the tertiary structure.

Thus, false is the correct answer.

What is happening in this photo
Ostrovityanka [42]

Answer:

Bacteriophages are attaching to bacterial cell wall and injecting genetic material.

Explanation:

Bacteriophage:

A bacteriophage (bacteria eater) is a type of virus that infects bacteria. Bacteriophages are composed of genetic material (DNA or RNA) enclosed in a protein shell or capsid.

Following are steps of bacteriophage infection:

  1. Bacteriophage attaches to cell surface receptors on the surface of the bacterium.
  2. Depending upon the type of phage, the bacteriophage either injects its DNA or RNA into the bacterium or enters as a whole. In this image, the bacteriophage T4 is represented which injects its genetic material into the host cell.
  3. The phage's genetic material hijacks the cellular machinery of the host and replicates itself within the host.
  4. After replication, the phages burst open the bacteria cell and are released. This is called the lytic cycle of bacteriophage infection.
  5. In another type of infection cycle, called the lysogenic cycle, the bacteriophage genome gets incorporated into the host genome, known as a prophage. This prophage lies dormant.

* The second step of the infection cycle is pictured here.
