Cell Wall
Explanation:
About 63% of the bacteria tested were Gram-negative, which means that they have a cell wall that is more resistant to certain classes of antibiotics than the cell walls of Gram-positive bacteria.
The tip of the pyramid ends in a cuplike structure called the papilla.
Papilla projects into a calyx. Its surface has a sievelike appearance since it is where urine droplets pass through its small openings. Each opening represents a tubule known as the Bellini duct through which collecting tubules within the pyramid converge or meet. The muscle fibers lead from the calyx to the papilla. As the muscle fibers originating from calyx contract, urine flows through the Bellini ducts into the calyx. The urine flows through the renal pelvis and the ureter and it eventually drains down into the bladder.
Minerals are identified according to their properties. One of these properties is their breaking tendency: <em>cleavage</em><em> or </em><em>fracture</em>.<em> Cleavage: Calcite, mica, muscovita, pyroxene. Fracture: Quartz, Asbestos, Limestone.</em>
<u><em>Note</em></u><em>: Since I do not know which your 10 minerals are, I will provide examples of each type according to the breaking tendency.</em>
Many properties of minerals are used to identify them, such as <em>color, density, hardness,</em> among others. In this case, we are talking about their <u>breaking tendency.</u>
<h3 /><h3>How do minerals break?</h3><h3 />
- Minerals can cleave or fracture.
- A type of mineral breaks always in the same, and this is why the breaking tendency is useful to identify them.
<h3 />
<u>- Cleavage</u>
- The mineral breaks in flat smooth planes.
- Cleavage direction and smoothness of surfaces are significant when identifying.
<u>- Fracture</u>
- The mineral break in irregular planes.
- In these minerals, there is no particular breaking direction.
<h2 /><h3>Examples</h3>
<u>- Cleavage</u>
<u>- Fracture</u>

Answer:
Thorns and colour.
Explanation:
The thorns are there to protect the stem from being cut or wild animals trying to eat it.
The colour is there to attract insects and pollinators to come and spread pollen.
