Answer:

Ecosystem.

Explanation:

Ecosystem is not a contributing factor to ecosystem stability whereas, species, genetic, and abiotic diversity are the factors that contributes in the stability of an ecosystem. The diversity of species greatly affected the ecosystem stability if more species are present in he ecosystem. The abiotic factors also plays an important role in the stability of an ecosystem because these abiotic factors causes changes in the ecosystem environmental conditions.

Explanation:

Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation.

Together with stratigraphic principles, radiometric dating methods are used in geochronology to establish the geologic time scale. Among the best-known techniques are radiocarbon dating, potassium–argon dating and uranium–lead dating.

Answer:

Over time, carbon-14 decays in predictable ways. And with the help of radiocarbon dating, researchers can use that decay as a kind of clock that allows them to peer into the past

Answer:

abnormal gland function. As we know, the meibomian glands secrete the meibum responsible for the formation of the tear film's outer layer. The meibum aids in reducing the evaporation of tears from the front surface of the eye, increasing the surface tension and forming an optically superior tear meniscus.

Answer:

Soil is a major source of nutrients needed by plants for growth. The three main nutrients are nitrogen (N), phosphorus (P) and potassium (K). Together they make up the trio known as NPK. Other important nutrients are calcium, magnesium and sulfur.

Explanation:

The best I could do

Through their roots, plants absorb water and mineral nutrients, returning organic matter to the soil through root exudates, litterfall, and roots. Thus, they can increase organic matter in the soil.

Through their roots, plants absorb water and mineral nutrients, and they return organic matter to the soil through litterfall, roots, and root exudates.

Avoid over-tillage while preparing seedbeds, and maintain the seedbed as coarse as you can to keep the aggregates big enough to hold gases and carbon. Any organic material input enhances soil quality. Organic matter enriches the soil with carbon while preserving the separation and integrity of the soil aggregates.

Answer:

Reactants: Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.

Products: Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

Parthenogenesis is a method in which a new individual developed without fertilization. Males do not have any role to play and only female gametes develop into new offspring.

Examples of plants showing parthenogenesis include honey bees, ants, and birds.

Answer:

Medicinal plants are considered as a rich resources of ingredients which can be used in drug development either pharmacopoeial, non- pharmacopoeial or synthetic drugs. A part from that, these plants play a critical role in the development of human cultures around the whole world.

The major use of herbal medicines is for health promotion and therapy for chronic, as opposed to life-threatening, conditions. However, usage of traditional remedies increases when conventional medicine is ineffective in the treatment of disease, such as in advanced cancer and in the face of new infectious diseases.

Aside from that, these plants play an important role in the development of human cultures all over the world. Flowers are important in nature because they can feed insects, birds, livestock, and humans; they can provide natural remedies for humans and certain animals; and they can help in plant reproduction by attracting outside pollinators. Plants would be only green in the absence of flowers, and the earth would be a duller place.

Answer:

they had to imagine a world in which evolution did not happen

Explanation:

Answer: Archaea, (domain Archaea), any of a group of single-celled prokaryotic organisms (that is, organisms whose cells lack a defined nucleus) that have distinct molecular characteristics separating them from bacteria (the other, more prominent group of prokaryotes) as well as from eukaryotes (organisms, including plants and animals, whose cells contain a defined nucleus).

Answer:

The lack of ATP would slow nerve responses to generate an action potential

Explanation:

Adenosine triphosphate (ATP) is the main source of energy in the cells. Moreover, ATPases are pumps that use ATP in order to transport sodium and potassium ions across the cell membrane and thus create an action potential. In stressful situations (e.g., escape from a predator) the lack of ATP would not allow to develop fast nerve responses, thereby ATP is required during rest periods and the flow of ions is used when is required a fast response.

Answer: A. Episodic

Explanation:

When you see a movie and remember the story because it had meaning to you, you are using Episodic memory.

The majority of the time, when someone mentions memory, they are referring to episodic memories, which include details of recent or previous experiences and events, such as where you parked your car this morning or the dinner you had with a friend last month.

Three stages of memory processing—encoding, consolidation/storage, and retrieval—are necessary for the memory to be able to recall past events.

The default mode network, which encompasses numerous brain areas including frontal and parietal regions and has been implicated in episodic memory functioning, contains the hippocampus and nearby structures in the temporal lobe, which are significant for episodic memory.

Therefore, When you see a movie and remember the story because it had meaning to you, you are using Episodic memory.

crytogams - this type of vascular plant reproduces by spore.

phanerogams - this type of vascular plant reproduces from the seeds, hence also named as seed plants.

Angiosperms - this type of vascular plant reproduces flowers and fruits

Gymnosperms - this type of vascular plant reproduces cones and seeds only.

Answer:

Vascular plants are plants that have roots, stems, and leaves. They have a vascular system that is responsible for the distribution of water and nutrients. This system is made up of the xylem (responsible for distributing the raw sap to the leaves) and the phloem (responsible for transporting the processed sap to the rest of the plant). Within this group we have: pteridophytes (Many plants do not produce flowers. They are also known as cryptogams. They reproduce through spores) and spermatophytes (they are vascular plants that produce seeds and, therefore, are the most evolved).

Explanation:

Vascular plants are those that have a “corm” made up of root and stem (stem and leaves), as well as a conduction system made up of xylem and phloem for transporting water and photosynthates. Pteridophytes are vascular plants that do not produce seeds. Within the vascular plants they are the simplest plants at a structural level, since they do not have the complexity linked to the production of these seeds, which are what allow the sexual reproduction of plants. Spermatophytes are the vascular plants that produce seeds. These seeds generated by the flowers, when they fall to the ground after dispersing, germinate and give rise to a new plant. This presence of seeds that can be spread by the wind or by animals is what has allowed these plant species to colonize the world.
