Answer:
It allows rapid conduction of water from one vessel element to the next.
Explanation:
Vessels are one of the two types of conducting cells of xylem. Vessels are made of vessel elements. Vessel elements are the individual cells with perforation plates. The perforation plates have large holes (perforations). Perforation plates of adjacent vessel elements allow easier conduction of water from one vessel element to the next.
The perforated end walls of vessel elements allow these conducting cells to conduct water more readily than tracheids. Stacking of vessel elements with perforated end walls make the vessel like a water pipe through which water is being readily conducted.

➷ Deforestation can contribute to global warming. Trees take in the carbon dioxide in the atmosphere, therefore, removing these would mean there is more carbon dioxide in the atmosphere. Also, growing certain things can release more greenhouse gases into the atmosphere. For example, rice cultivation releases methane into the atmosphere. Furthermore, growing livestock would increase methane emissions. This would mean the global temperature would increase due to global warming.
b) Permacultures may be used. These mimic natural processes and create sustainable and self - sufficient ecosystems. Another method would be stacking. This is where more things are grown in a given space. The plants would absorb more carbon dioxide from the atmosphere.

Answer:
A) Dendritic cells and macrophages, although they are also found in other cells that belong, or not, to the immune system.
B) The innate immune response
Explanation:
The immune system is equipped with specialized receptors for the detection of pathogens such as bacteria or viruses, which are called receptors that recognize patterns (PRRs). These proteins are a key element in the innate system and are expressed primarily in antigen presenting cells, such as <u>dendritic cells and macrophages, although they are also found in other cells that belong, or not, to the immune system.</u>
<u>
The innate immune response</u> begins with the recognition of highly conserved molecular structures and present in large groups of microorganisms called 'molecular patterns associated with pathogens' (PAMP). This recognition is done by the 'pattern recognition receptors' (RRP) of the host.
The best known bacterial PAMPs are:
Lipopolysaccharides (LPS)
Peptidoglucan
Lipoteic Acids
Mananas (Mannose
)
Bacterial DNA
Double stranded RNA
Glucans
These PAMP are essential for the survival and pathogenicity of bacteria.
