The part of the dermal tissue consisting of hard, dead, cork cells is known as the periderm, which forms the protective bark in woody plants and serves as a defense against various environmental stresses.
The part of the dermal tissue that is made of hard, dead, cork cells is the periderm. In woody plants, the protective outer layer of dermal tissue is known as bark, which includes the cork cells. These cells are produced by the cork cambium, and upon maturation, they die and form a protective barrier.
The dermal tissue consists primarily of the epidermis, which in woody plants, is eventually replaced by the periderm as secondary growth occurs. This cork layer functions as a defense against environmental stress like dehydration, extreme temperatures, and potential pathogens.
Scientists use whale flukes to identify individuals in a population. Which of the following characteristics of a whale fluke is not a genetic variation passed on from parent to offspring?
A.) Coloration of the fluke
B.) Shape of the fluke
C.) Size of the fluke
D.) Scars on the fluke
Answer:
The correct answer is option D, Scars on the fluke
Explanation:
The naturally existing characteristics such as colour, shape and size of any organism are linked to the genetic traits expressed. Only genetically controlled characteristics are passed on from generation to generation.
However, scars on the body (are caused due to external environmental factors) are not genetically controlled feature and thus it will not be passed on from parents to offspring.
Answer:
I just took the test
Explanation:
the correct answer is D. Scars on the fluke.

Martin buber states that "i-it" and "i-thou" represent two ways in which humans can relate to one another. what is the difference between these two types of relationships?
The difference is that
I-It" relationships are stable, predictable, and detached.The I-Thou relationships does takes place relations with nature, humans or with spiritual beings. It is often due to both at moments of real dialogue or indifference.
This relationship is known by mutuality, being direct, being present, intensity etc. Buber stated that it is a bold leap into the experience of the other.
I-It is a relationship of subject-to-object.
Conclusively, based on Buber interpretation, human beings do uses two attitudes toward the world that is the I-Thou or I-It.

14. How does the camouflage of a butterfly’s cocoon relates to function
Answer:
Butterfly cocoon camouflage is related to the protective function because it prevents the cocoon from being attacked by predators.
Explanation:
The cocoon of butterflies and moths has the function of protecting the larva during metamorphosis. Some species, however, present the cocoon with the ability to camouflage the surrounding environment. This camouflage provides even greater protection as the cocoon is disguised and goes unnoticed by the attention of predators.

Most extinction is ________.
a. gradual, generally occurring when species cannot adapt genetically to changes in environmental conditions
b. the result of slow climate change
c. the result of environmental catastrophe
d. problematic for generalists
e. not often a problem for endemics
An extinction event is a well-known and quick decrease in the biodiversity on Earth. Such an occurrence is recognized by a sharp change in the diversity and abundance of multicellular organisms. It happens when the rate of extinction surges with respect to the rate of speciation. In other words, this happens when species cannot adapt generally to the change in the environment. So the correct answer would be letter a.
The majority of extinctions take place gradually, usually because a species fails to adapt genetically to shifting environmental circumstances. It is not always tied to environmental catastrophes or climate changes. Specialists or endemic species, which have adapted to a specific environment, are more prone to extinction than generalist species.
Explanation:Most extinction is gradual, generally occurring when species cannot adapt genetically to changes in environmental conditions (Option a). This is primarily due to the slow nature of genetic evolution which cannot keep pace with sudden drastic changes in environmental conditions. Over the vast geological timescales, many species have disappeared due to such inability to adapt. It is not always linked to catastrophic events or climate changes. Moreover the problem of extinction more critically affects specialists and endemics, rather than generalists. Specialists or endemics are species that are adapted to a very specific type of environment, and hence have less flexibility to adapt to changes compared to generalists.

5.How does temperature change affect surface tension?
The nurse receives a report from labor and delivery on an infant and mother couplet. which reported apgar score will the nurse prioritize for close observation for the entire transition period?
No. The mother needs full support from the nurse during the transition period but APGAR test (Appearance, Pulse, Grimace, Activity, and Respiration) is done only twice to a baby. The first- one minute after birth and the second, 5 minutes after.
The correct answer is the Apgar score that is less than 7 at 5 minutes after birth.
The Apgar score is a quick method to assess the health of a newborn infant immediately after birth. The score is usually taken at 1 and 5 minutes after birth, and may be repeated later if the score is low. The Apgar score consists of five components: Appearance (skin color), Pulse (heart rate), Grimace (reflex irritability), Activity (muscle tone), and Respiration, each of which is scored from 0 to 2, giving a total score of 0 to 10.
A score of 7 to 10 is generally considered normal, 4 to 6 fairly low, and 0 to 3 critically low. A 5-minute Apgar score of less than 7 warrants close observation because it indicates that the infant may require medical intervention to support their transition to extrauterine life. Infants with a 5-minute Apgar score in this range are at a higher risk for complications such as difficulty breathing, low blood sugar, or infection.
Therefore, the nurse will prioritize for close observation any infant with a reported Apgar score of less than 7 at 5 minutes after birth during the entire transition period, which is the first hour after birth when the infant is adapting to life outside the womb. This is crucial for early identification and management of any potential issues that could affect the infant's short-term and long-term health outcomes."

Which is the best criteria to use when classifying cells as either eukaryotes or prokaryotes?
Cells are classified as eukaryotic or prokaryotic based on the presence of a membrane-bound nucleus and organelles. Eukaryotic cells have these structures, while prokaryotic cells do not. Techniques like ribosomal RNA gene sequencing have reinforced the classification and evolutionary relationships.
The best criteria to use when classifying cells as either eukaryotes or prokaryotes involve noting the presence or absence of a membrane-bound nucleus and organelles. Eukaryotic cells have membrane-bound organelles, including a nucleus, which houses the cell's DNA. In contrast, prokaryotic cells lack a membrane-bound nucleus and organelles. Bacteria and Archaea are examples of prokaryotes, whereas animal cells, plants, fungi, and protists are eukaryotes. Biologists like Carl Woese have studied cells and their classifications by using techniques such as ribosomal RNA gene sequencing to determine the evolutionary relationships between these two groups.
____________ are novel prokaryotic organisms that belong to their own superkingdom (domain).
