What do you call the end of a straw wrapper that a waiter leaves on your straw when serving your drink?
daser333 [38]

The waiter tears the raised part of the straw wrapper a few inches from either end and he pulls until a piece of the wrapper is entirely removed. The exposed part of the straw is what is then placed in the drink, leaving the remaining wrapper for the customer to remove himself. This will assure the customer that the waiter has not touched the straw with bare hands. The part of the straw that has remained is called a straw lace, or a drinking straw sleeve or a strawphylactic.

Astronomers studying the planet of Rhombus have detected sedimentary rock on its surface. One astronomer wonders if material in
Gwar [14]
Answer:
igneous rock CAN become sedimentary rock through a process called ROCK CYCLE.
Explanation:
Rocks can be defined as solid structures of minerals that are formed naturally over a period of time. They are grouped into three main types which includes the following:
- igneous rock
- sedimentary rocks and
- metamorphic rocks.
Rocks are capable of transforming from one type to another through a process known as rock cycle. There are two forces that brings about this process which includes:
- The internal force : this is the Earth’s internal heat engine, which moves material around in the core and the mantle and leads to slow but significant changes within the crust.
- The external force: this is the the hydrological cycle, which is the movement of water, ice, and air at the surface, and is powered by the sun.
Molten magma cools to form either extrusive igneous rock or intrusive igneous rock. With time they undergo weathering, eroded, transported, and then deposited as sediments which are being compressed and cemented into SEDIMENTARY ROCKS. Again through the above mentioned forces, different kinds of rocks are either uplifted, to be re-eroded, or buried deeper within the crust where they are heated up, squeezed, and changed into METAMORPHIC ROCK.
Therefore the material in this sedimentary rock found in Rhombus planet used to be in igneous rock deep in Rhombus's interior due to continuous rock cycling on the planet. I hope this helps

The epidermis is a barrier to ultraviolet rays, blocking much of the cancer-causing radiation from reaching the nuclei of cells
UkoKoshka [18]

The epidermis is a barrier to ultraviolet rays, blocking much of the cancer-causing radiation from reaching the nuclei of cells called keratinocytes.

<h3>What is keratinocytes?</h3>
  • Skin cells, also known as epidermal keratinocytes, are highly specialized epithelial cells created for a very specific purpose: separating the organism from its environment.
  • Keratinocytes, which make up the majority of the epidermis, have a variety of functions that are crucial for skin restoration.
  • They carry out the re-epithelialization process, in which keratinocytes move, multiply, and differentiate in order to reestablish the epidermal barrier.
  • The majority of the epidermis's cells, known as keratinocytes, begin in the basal layer, manufacture keratin, and help to create the epidermal water barrier by producing and secreting lipids.
  • A kind of stratified epithelium known as keratinized stratified squamous epithelium has many layers of squamous cells, or keratinocytes, with the superficial layer of cells being keratinized.
  • The skin's epidermis is made up of this kind of epithelium.

PLEASE CAN SOMEONE HELP ME WITH THIS SCIENTIFIC METHOD TEST.PLEASE
stiv31 [10]

<u>Answer</u>: a. This represents the requirements for the highest quality scientific methodology.

This question is part of the problem solving value rubric created by the AACU (The Association of American College and Universities). The number 4 represents the score assigned to the experimental design and the text illustrates the requirements needed to reach it.

a - is the highest score - the capstone

b&c - the milestones

d - the benchmark - the minimum score needed to pass.

Anything lower than the benchmark will be assigned a 0 and failed.
