Explanation:
How and why does the epidermis produce new skin cells?
Answer:
About 95 percent of the skin cells in the epidermis are devoted to creating new skin cells in the lower two levels of the epidermis, which then cycle to the top layer to help form the stratum corneum. Eventually the dead cells of the stratum corneum flake off as new keratinocytes move up, and the cycle repeats itself.

blue and violet are the shortest
describe the effect of temperature on transpiration rate
Answer:
Temperature affects the transpiration rate in two ways. Firstly, at warmer temperatures water molecules move faster, and the rate of evaporation from stomata is therefore much faster. Secondly, the water-holding capacity of warm air is greater than that of cold air.
Explanation:
I hope it helps you
Answer:
Temperature: Transpiration rates go up as the temperature goes up, especially during the growing season, when the air is warmer due to stronger sunlight and warmer air masses. Wind and air movement: Increasing movement of the air around a plant will result in a higher transpiration rate.

How do transitional fossils help explain the evolutionary steps that took place to produce modem organisms?
Answer:
Transitional fossils show how a particular taxa accumulated adaptations to fit particular environments and/or ecological niches
Explanation:
Transitional fossils are fossilized remains of taxonomic groups/species that illustrate an evolutionary transition between a known version of a taxa/species and the current taxa/species. Transitional fossils are fundamental because they can be clearly differentiated from the ancestral group as well as of its derived descendant group. For example, there exist transitional fossils known as "mammal-like reptiles"(i.e., therapsids that gave rise to the true mammals), which are clearly different from current mammals.

Discuss how the concept of "survival of the fittest" was developed and what it means.
Explanation:
Survival of the fittest is a phrase that originated from Darwinian evolutionary theory as a way of describing the mechanism of natural selection.In On the Origin of Species, he introduced the phrase in the fifth edition published in 1869, intending it to mean "better designed for an immediate, local environment".

Osmolarity tells you the concentration of solute particles in solution, osmolarity cannot always tell you the direction of water movement across a membrane.
a. True
b. False
Answer:
a. True
Explanation:
Osmolarity is a measure of solute concentration, that is, it indicates how much solute there is in a liquid. As we know, osmosis is the movement of solute across the cell membrane, where the solute passes from the more concentrated side to the less concentrated side. Osmolarity is directly linked to this concept, but it is not able to indicate the direction of movement of the solute. This is because the solute will only pass through the membrane if it is a penetrating solute. Non-penetrating solutes do not have the ability to move through the membrane, even though the osmolarity of the liquid is high.

The growth of the human population directly relates to the use of natural resources by humans. Based on the graph, which two statements about human use if natural resources are most likely true?
A. resources use by humans will be higher in 20 years than it is now
B. resource used by humans is much higher now than it was 200 years ago
C. Resource used by humans in steadily decreasing over time
D. Resource used by humans is about the same now as it was 150 years ago
Answer:
A. resources use by humans will be higher in 20 years than it is now
B. resource used by humans is much higher now than it was 200 years ago
Explanation:
The growth of the human population has direct relation with the use of natural resources by humans means if the population of humans increases, more natural resources will be consumed by the population. Directly relation means if one increases the other automatically and vice versa. more population needs more resources for their growth and survival so we can conclude that resources used by humans will be increases if the population increases.
What is the kind of asexual reproduction
Comb jellies are:____.
A. Bilaterally symmetrical.
B. Similar to a cnidarian polyp.
C. Distinguished by eight bands of cilia.
D. Colonial animals.
E. Carnivores that use nematocysts to capture prey.
Answer:
C. Distinguished by eight bands of cilia.
Explanation:
Ctenophora, also known as comb jellies, represents a phylum of transparent, mostly pelagic, invertebrate marine animals that live around the world. This group characterized by eight rows of cilia (singular cilium) that are used for locomotion. Cilia are organelles and/or structures that extend from the surface of eukaryotic cells, which can be used to move the surrounding fluid, resulting in cell movement. This phylum is divided into two classes: Tentaculata (with tentacles) and Nuda (without tentacles).
The predatory bacterium Bdellovibrio bacteriovorus is able to penetrate a gram-negative bacterium that has a slimy cell covering. What is the correct sequence of structures penetrated by B. bacteriovorus on its way to the prey's cytoplasm
Answer:
The order of bacterial structures that the bacteria would penetrate would be:
Capsule.Lipopolysaccharide MembranepeptidoglycanPhospholipids Membrane.Explanation:
A parasite like B. bacteriovorus faces some challenges in getting into a bacterial cell. This is because these cells have devices and strategies to prevent the entry of parasites and ensure the survival of the bacteria. The first challenge would be to penetrate the bacterial capsule. The capsule is a structure that is located around many bacteria. This structure is rigid, with sharp edges and thick thickness, which protects the bacteria from external agents. If B. bacteriovorus manages to go beyond the capsule, it will find a membrane, also thick, composed mainly of lipopolysaccharides, which will also provide protection and try to prevent the entry of the parasite. If this membrane is crossed, B. bacteriovorus will face another layer called peptidoglycan. This layer establishes itself as a cell wall, being very difficult to break. Some bacteria present one more layer after peptidoglycan, which is a membrane made by Phospholipids, which is highly selective and difficult to break, but is more fragile than the previous layers. Only after overcoming all these structures, the parasite will have access to the bacterial cel

Excess postexercise oxygen consumption (EPOC) is also known as oxygen debt.
a. True
b. False
Answer:
True.
Explanation:
Excessive postexercise oxygen consumption can also be called oxygen deficit. It occurs after an individual completes a physical activity. Physical effort does not allow oxygen consumption to be normalized as soon as the body comes to rest and for this reason, the body begins to breathe and demand oxygen more intensely. This moment is known as excessive postexercise oxygen consumption, or oxygen debit. The intensity of breathing at this time will depend on the physical effort made, the weight loss and the increase in total caloric expenditure.

Like DNA, RNA follows base-pairing rules. Experiment to find which RNA _____________ on the right side of the Gizmo will successfully pair with the thymine at the top of the template strand of DNA.
Answer: Nucleotide; Adenine
Explanation: RNA Nucleotide contains bases of Thymine, Cytosine, Guanine and Uracil. The Uracil base in RNA, substitute the base Thymine in the DNA base and bonds with Adenine like as seen in DNA base pairing.
Thus, during DNA duplication, the thymine at the top of the template strand of DNA is replaced with Uracil and binds with Adenine.

Which organelle should be listed under "Animal Only" in the diagram?
Organelle which is present in only plant cells are chloroplast, centrioles are present only in animal cells. The organelles present in both cells are ribosomes, nuclei, and mitochondria.
What are organelles?The cell parts are called cell organelles. There are both membrane-bound and non-membrane-bound organelles in these cell organelles, which are found within the cells and have distinct structures and functions. The direction and capability productively for the ordinary working of the cell.
Depending on whether or not they have a membrane, the various organelles that are found within the cell are divided into three groups. The types are double membranes, single membranes, and no membrane organelles.
Therefore, organelles perform biochemical functions.
