What is one major impact of seedless vascular plants?
The vascular seedless plants are utilized as the medicinal plant and fertilizer.
Further Explanation:
The vascular plants are those plants that possess xylem and phloem for the transport of water and food respectively. Plants that have vascular system but are seedless are the members of Pteridophytes.
The characteristics of Pteridophytes:
1. They are seedless and vascular cryptogams: They reproduces through the production of spores.
2. They show alternation of generation as the sporophytic generation alternates with the gametophytic generation: Sporophyte possess true root, stem and leaves.
3. Spores are developed in the sporangia. Both type of spores are developed- homosporous and heterosporous.
4. Sex organs are multicellular and are jacketed.
Some of the example of Pteridophytes are:
1. Equisetum
2. Salvinia
3. Dicksonia
4. Selaginella
The importance of pteridophytes:
1. They are used as cattle feed
2. They are used for medicinal purpose. For example the foliage decoction of Lycopodium is utilized in homeopathy to treat certain disease such as constipation, eczema, diarrhea and inflammation of liver. Equisetumcontains various flavonoid and saponina that have diuretic effect.
3. Marsilea contains starch and are consumed by people as food in some areas.
4. Aquatic pteridophyte such as Azollaare used as a very good biofertiliser.

We have already talked about another class of chemicals that help send signals in the body – neurotransmitters. how are neurotransmitters and hormones similar and how are they different
Final answer:
Neurotransmitters and hormones serve as chemical messengers in the body, with neurotransmitters traveling short distances for precise communication between neurons, while hormones travel longer distances through the circulatory system to reach target cells. Neural messages are likened to train travel, limited to nerve tracts, while hormonal communication is akin to car travel, reaching any cell via blood flow. Neural messages are faster, whereas hormonal messages can lead to enduring changes.
Explanation:
Neurotransmitters and hormones both serve as chemical messengers in the body. Neurotransmitters are used by neurons and travel short distances to bind with receptors on postsynaptic neurons, while hormones enter the circulatory system to travel longer distances to reach target cells and bind with specific receptors.
Neural messages are like traveling on a train, limited to existing nerve tracts, while hormonal communication is compared to traveling in a car, able to reach any cell receiving blood via the circulatory system. The speed of neural messages is faster due to the short distance traveled, while hormonal messages can result in long-lasting changes throughout the body.

Which set of body parts does every mollusk have?
The body plan of a mollusk ordinarily comprised of a head region, a muscular foot, and a visceral mass of abdominal organs that are usually enclosed inside a dorsal shell. Each class holds some contrast on this primary plan.
The structure of the gastropod body is substantially comparable to the primary body plan of mollusks.
Most mollusks have a muscular foot for crawling or burrowing. Some mollusks also have a head with sense organs. The delicate body comprises lungs or gills to breath and digestive and generative parts, all surrounded by a covering like an organ known as the mantle.

Choose the factor that is likely to limit population growth.
Limiting factors are the resources that can limit population growth. It can include keystone species, predator, energy, available space, disease and food supply etc.
What are the limiting factors for population growth?Population growth limiting factors are either density-dependent or density-independent.
Density dependent factors can include disease, competition and predators while density independent factors can include harsh weather, limited food supply, lower quantity of nutrients etc.
Thus, in the given question, option D is correct.

What is the name of muscle's state of perpetual partial tension?
Muscle tone, or tonus, is the state of perpetual partial tension in muscles. It allows muscles to maintain posture and readiness for action, while muscle tension can vary to handle different levels of load.
The name of the muscle's state of perpetual partial tension is muscle tone or tonus. This state helps to maintain posture and ensures that muscles are ready for action. The control of muscle tension involves neural control that initiates the formation of actin-myosin cross-bridges. The tension a muscle produces can vary, allowing it to handle different levels of load, from light objects to heavy objects. During an isotonic contraction, tension in the muscle remains constant as the muscle changes length. Factors like the cross-sectional area of the muscle fiber and the frequency of neural stimulation influence the amount of tension produced.

What are restriction enzymes?A restriction enzyme, restriction endonuclease, or restrictase is an enzyme that cleaves DNA into fragments at or near specific recognition sites within molecules known as restriction sites. Restriction enzymes are one class of the broader endonuclease group of enzymes.
Moreover, a restriction enzyme is a protein isolated from bacteria that cleaves DNA sequences at sequence-specific sites, producing DNA fragments with a known sequence at each end. The use of restriction enzymes is critical to certain laboratory methods, including recombinant DNA technology and genetic engineering.
Therefore, four types of restriction enzymes are recognized, designated I, II, III, and IV, which differ primarily in structure, cleavage site, specificity, and cofactors.
