Answer:
19.32 m²
Explanation:
The area of a living room is the product of its length and breadth. The area is given by:
Area = length × breadth
1 meter = 3.28 feet. Hence:
Length = 16 ft
16 ft = 
Breadth = 13 ft
13 ft = 
Area = length × breadth = 4.88 m × 3.96 m = 19.32 m²
Hence 19.32 m² of carpet is needed for the living room
The correct answer is option A, It grows healthy crops.
Because the loess soil is very fertile due to its ability to exchange cations and porosity.
Due to cation exchange capacity the plants easily absorbs nutrients from the soil and due to porosity the soil holds the water, oxygen and nutrients which is absorbed by the roots of the plants for their nourishment.
Answer:
This happens because viruses mutate and vary according to the environment they face. That is why different strains occur and appear every day, which must be updated in the vaccines, in order to have immunity up to date and keep up with the viral mutation without making us sick.
Explanation:
Viruses are acellular structures that do not have their own metabolism or replication method, it is because they must dominate and invade the human body so that its DNA or RNA is coupled to the human and this uses the human machinery to be able to replicate.
On the other hand, as infections occur and viruses appear, they can associate with bacteria forming bacteriophages, they can mutate within an organism that is infected by more than one viral infection and they can even adopt retrovirus mechanisms, which day by day. These new viruses are called as new strains, which evolve and will have to be coupled with vaccines.
Vaccines are a method of natural ACTIVE immunity, that is, part of the virus is inoculated, so that it generates the formation of a specific antibody in the body.
The correct answer is the extensor digitorum longus and fibularis tertius.
The pretibial muscles include the anterior tibialis, extensor digitorum longus, extensor hallucis longus, and peroneus tertius. As a group they are active during the swing phase and the heel-strike to foot-flat phase of gait. Fibularis is often considered as part of the extensor digitorum longus muscle.
