Answer:
The correct answer is D.
Explanation:
The plants are grouped formally into 12 phyla (phylum plural) and are collected in four groupings. These four groupings are based on the history of the evolution of important plant characteristics:
Nonvascular plants evolved earliest. They are distinct from the algae because they preserve the embryo inside of the reproductive structure after fertilization. There is no vascular tissue, xylem, and phloem for these plants to convey nutrients, water, and food. For example, moose, liverwort, and hornworts. These plants do not grow very high without vascular tissue.Vascular seedless plants have evolved into non-vascular tissue but no seeds. The fern, fern, club moss, and horsetails are examples. These plants could grow larger with vascular tissue.Gymnosperms have evolved into seeds but have no blooms. For example, redwood, fir, and cypress trees. Gymnosperms. Gymnos in Greek means "naked"; the gymnosperm seeds are bare, not floral.Flowers or angiosperms have developed into vascular tissue, seeds, and flowers. Angiosperm for example includes magnolia, roses, tulips, and tomatoes.Answer:

Write a supported hypothesis of how the body would react if the peripheral nervous system was shut down while the central nervous system continues to function.
Explanation:
The real magnitude of this challenge can perhaps be best judged by considering the structural and functional complexity of the human brain and the bewildering complexity of human behavior. The human brain is thought to be composed of about a hundred billion (1011) nerve cells and about 10 to 50 times that number of supporting elements or glial cells. Some nerve cells have relatively few connections with other neurons or with such effector organs as muscles or glands, but the great majority receive connections from thousands of other cells and may themselves connect with several hundred other neurons. This means that at a fairly conservative estimate the total number of functional connections (known as synapses) within the human brain is on the order of a hundred trillion (1014). But what is most important is that these connections are not random or indiscriminate:
They constitute the essential "wiring" of the nervous system on which the extraordinarily precise functioning of the brain depends. We owe to the great neuroanatomists of the last century, and especially to Ramón y Cajal, the brilliant insight that cells with basically similar properties are able to produce very different actions because they are connected to each other and to the sensory receptors and effector organs of the body in different ways. One major objective of modern neuroscience is therefore to unravel the patterns of connections within the nervous system—in a word, to map the brain.

Explanation:
What term describes the organisms that obtain energy from dead organic matter and aid nutrient cycling
Answer:
Decomposers.
Explanation:
Decomposers are the organisms that obtain energy from dead organic matter and help in nutrient cycling. The example of such type of organisms are bacteria and fungi. These organisms feed on the dead bodies of plant and animals. It perform two function i.e. clean the environment by removing the dead body through feeding on it and add nutrients in the soil which helps the plants to grow more efficiently.
During the process of genetic recombination, crossing over occurs between two nonsister chromatids. DNA segments are exchanged between two nonsister chromatids during meiosis I. None of the above. maternal and paternal chromosomes pair and physically exchange DNA segments. All of the above.
Answer:
DNA segments are exchanged between two non-sister chromatids during meiosis I.
Explanation:
An exchange of chromosome segments or parts between non-sister homologous chromatids occurs which is also called crossing over. This crossing over occurs in the meiosis I that is responsible for the variation in the offspring produced. The formation of hybrid species occurs due to this exchanged of DNA segments between two non-sister chromatids.

The fibrous protein that gives skin its flexibility and helps skin regain its shape after being expanded is:
Answer:
Elastin
Explanation:
The elastin is defined as an extracellular matrix protein which lends to the elasticity and also resilience to the tissues such as the lungs, skin, arteries, tendons, and the ligaments.
Elastin synthesized from precursor molecule named tropoelastin.
Elastin is the fibrous protein which gives the skin its flexibility and also helps the skin regain its shape.
Why do biologists classify
Answer:
Biologists classify organisms because:
Classification allows us to understand diversity better. It helps in the identification of living organisms as well as in understanding the diversity of living organisms. Classification helps us to learn about different kinds of plants and animals, their features, similarities and differences. It enables us to understand how complex organisms develop from simpler organisms. They are grouped under different categories to understand and study the features, similarities and differences between different living organisms. It is essential to understand the inter-relationships among the different groups of organisms. Classification forms a base for the development of other biological sciences.A small child managed to eat a bit of dirt while playing outside.

Many antibiotics work by preventing the proper synthesis of the peptidoglycan cell wall. These antibiotics are most likely to be effective against what types of bacteria
Answer: Gram-positive bacteria.
Explanation:
Gram-positive bacteria are those bacteria that stain dark blue or violet by Gram staining. This is due to the structure of the cell envelope, since they possess a cell wall composed of a thick layer of peptidoglycan, which surrounds the previous one. The cell wall is attached to the cytoplasmic membrane by lipoteichoic acid molecules. The peptidoglycan layer confers high resistance to these bacteria and is responsible for retaining the stain during Gram staining. Unlike gram-positive bacteria, gram-negative bacteria have a second lipid membrane outside the cell wall and a single peptidoglycan layer.
An antibiotic is a chemical substance produced by a living being or synthetically derived, which kills or prevents the growth of certain classes of sensitive microorganisms, such as bacteria. An antibiotic could be bacteriostatic if it prevents the growth of bacteria or bactericidal if it destroys them.
Antibiotics usually attack cell walls, such as β-lactams that act on the peptide chains of the bacterial cell wall. That is, they act by inhibiting peptidoglycan synthesis. This is why gram-positive bacteria are susceptible to certain types of antibiotics because they possess a large amount of peptidoglycan.
During cellular respiration, the first CO2 is generated during _____ and the remaining carbons are given off as CO2 during _____.
Answer:
Glycolysis and Krebs cycle.
Explanation:
During cellular respiration, the first carbondioxide gas is generated during glycolysis while the remaining carbons are given off as carbondioxide during Krebs cycle. During the process of glycolysis in cellular respiration, glucose is oxidized forming carbondioxide and water whereas during the Krebs cycle, the two carbon atoms of acetyl-CoA are released and each turns into a carbondioxide molecule.

how are proteins and nucleic acids related
Answer: Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins. A related type of nucleic acid, called ribonucleic acid (RNA), comes in different molecular forms that participate in protein synthesis
Explanation:
Each of the following will result in complement activation EXCEPT Group of answer choices TLR binding to PAMP on the microbe. recognition of lipid-carbohydrate molecules on the surface of the microbe. lectin binding to mannose on the surface of the microbe. Antibody binding to antigen. All of these will result in activation of complement.
Answer:
TLR binding to PAMP on the microbe
Explanation:
The complement system is a group of proteins in the blood that enhance immune responses by complementing the ability of antibodies and phagocytic cells to mediate effector responses (e.g., lysis, activation of inflammation, opsonization, solubilization of immune complexes, etc). Complement can be activated through the recognition of microbes by soluble pattern-recognition molecules (i.e., lectin pathway) or antibodies (i.e., classical pathway). The classical pathway requires the formation of antigen-antibody complexes for its activation (it is a specific immune response). On the other hand, Toll-like Receptors (TLRs) are molecular receptors that recognize viral and bacterial products (i.e., pathogen-associated molecular patterns or PAMPs), which is a key defense mechanism from the innate immune system response.
