Which of the following is NOT a characteristic of the northern boreal forest (taiga) biome?
Alik [6]

Answer: d. High biodiversity in the understory.

Explanation:

The taiga or boreal forests are the largest biome in the world. These can be found in the regions of North America, Alaska, and United States. These regions exhibit extreme weather conditions. Typically long winters and moderate to high precipitation. The soil is permafrost and nutrient poor as no new organic matter can be added up to the soil due to it's freezing condition. The plant growth is scanty and biodiversity is low because organisms are incapable of surviving in the harsh weather conditions.

VMariaS [17]

Answer:

Linear DNA is unstable in bacterial cells and unless the lac+ gene is recombined into the bacterial chromosome, it will be destroyed.

Explanation:

Bacterial recombination is a kind of hereditary recombination in microorganisms described by DNA move starting with one life form called giver then onto the next creature as beneficiary. This cycle happens in three principle ways:  

1. Change, the take-up of exogenous DNA from the general condition.  

2. Transduction, the infection interceded move of DNA between microscopic organisms.  

3. Formation, the exchange of DNA starting with one bacterium then onto the next by means of cell-to-cell contact.

Recombination into the bacterial chromosome necessary because linear DNA is unstable in bacterial cells and unless the lac+ gene is recombined into the bacterial chromosome, it will be destroyed.

Which of the following is an example of the skeletal system interacting directly with the
Nadusha1986 [10]

A.

<u>The ribcage expands to allow air to enter the lungs</u> is an example of the skeletal system interacting directly with the respiratory system.

Explanation:

The skeletal system is mainly made up of bones - like the ribcage in this case - while the respiratory system is made up of the lungs, trachea, diaphragm, etc.  

When inhaling, the diaphragm contracts, therefore increasing the volume of the chest cavity. The muscles between the ribs also contract causing the ribcage to stretch upwards and outwards. This also contributes to an increase in the volume of chest cavity. Consequently, the pressure in the chest, decreases causing atmospheric pressure to rush  air into the lungs.

When these muscles contract, they raise the pressure in the chest cavity causing air to rush out of the lungs.
