What do dermal tissues in plants do
Answers
Answer:
The dermal tissue system protects the soft tissues of plants and controls interactions with the plants' surroundings. The epidermis is a dermal tissue that is usually a single layer of cells covering the younger parts of a plant. It secretes a waxy layer called the cuticle that inhibits water loss.
Primary dermal tissues, called epidermis, make up the outer layer of all plant organs (e.g., stems, roots, leaves, flowers). They help deter excess water loss and invasion by insects and microorganisms.

describe the significance of mitosis for unicellular algae.
Answers
Answer:
Mitosis plays an important part in the life cycle of most living things, though to varying extents. In unicellular organisms such as bacteria, mitosis is a type of asexual reproduction, making identical copies of a single cell. In multicellular organisms, mitosis produces more cells for growth and repair.

B. The cell would not be able to stop things from getting in and out
C. Materials would not be transported
D. Proteins would not get made
Answers
Answer:
D. Proteins would not get made
Explanation:
According to google: If the ribosomes were not working properly then your cell would not be producing proteins. If your cell did not produce proteins enzymes would not be available to speed up reactions throughout your body, and they would also not be available to make the many organelles made with proteins such as microtubules which would cause many other problems within the cell.

D. Proteins would not be made.

what are the stratigraphic principles?
Answers
Answer:
There are 6 of these...
Law of Superposition
The geologic principle that states that in horizontal layers of sedimentary rock, each layer is older than the layer above it and younger than the layer below it.
Principle of Original Horizontality
The geologic principle that states that sediments are deposited as essentially horizontal beds.
Principle of Lateral Continuity
The geologic principle that states that strata originally extended in all directions until it thinned out to zero or ended against the edges of another structure or deposit.
Principle of Cross-cutting Discontinuities
The geologic principle that states that any discontinuity that cuts across a stratum must have formed after that stratum.
Law of Inclusions
The geologic principle that states that any piece of rock that has become included in another rock or body of sediment must be older than the rock or sediment into which it has been incorporated.
Law of Faunal Succession
The geologic principle that states that sedimentary rocks that contain fossils succeed each other in specific and reliable order.
After cooking the hot dogs, your friend's mom reminds you not to leave the grill out, or the iron (Fe) in the grill will react with oxygen (O2) in the air to produce rust (Fe2O3). a. Write a balanced equation for this reaction. Be sure to show your work.
Answers
Answer:
Explanation:
Oxygen gas and water must be present for iron to rust.
A region of the metal’s surface serves as the anode, where oxidation
occurs:
Fe(s) → Fe²⁺ (aq) + 2 e⁻
The electrons given up by iron reduce atmospheric oxygen to water at the cathode, which is another region of the same metal’s surface:
O₂ (g) + 4H⁺ (aq) + 4 e⁻ → 2 H₂O (l)
The overall redox reaction is:
2 Fe(s) + O₂(g) → 4H⁺(aq) + 2Fe²⁺ (aq) + 2 H₂O(l)
The Fe²⁺ ions formed at the anode are further oxidized by oxygen:
4 Fe²⁺ (aq) + O₂(g) 1 (4 + 2x) H₂O (l) → 2 Fe₂O₃ . xH₂O(s) + 8 H⁺(aq)
This hydrated form of iron(III) oxide is known as rust. The amount of water associated with the iron oxide varies, so we represent the formula as 2 Fe₂O₃ . xH₂O.
In order to maintain homeostasis, the human body must be able to get rid of the waste products produced by cellular processes. The kidneys, for example, are responsible for removing waste from the bloodstream by producing urine. Urine produced in the kidneys then travels through the ureter and into bladder, and is finally expelled from the body by the urethra.

Which area of Earth is most similar to the sun’s convection zone?
Answers
Answer:
The Mantle
I hope this helps
The mantle is the part which is the most similar to the sun’s convection zone. It is the second layer of Earth.
Which layer from Earth's atmosphere is convective in nature ?It is the troposphere that is convective in nature. Troposphere means the region of mixing.
The mantle is the most similar to sun's convection zone. Sun's convection zone is later dominated by the convection currents that carries energy outward to surface. Mantle is second layer of Earth.
The zone is not that dense enough to just use the radiative transfer of the energy, infact , they uses the thermal convection zones in just other words then it boils. Energy is then carried out through the thermal columns to surface of sun and later creates out areas that are seen as the solar granulation and the super granulation.
