Answer:

Los desarrollos científico-tecnológicos han impactado positivamente sobre los sistemas de agricultura ecológica y en última instancia también sobre la agricultura familiar

Explanation:

La agricultura ecológica refiere a los procedimientos de explotación agrícola basados en la utilización sustentable de los recursos de la tierra y los métodos de fertilización orgánica, respetando el ambiente natural y evitando el uso de compuestos químicos artificiales (como por ejemplo plaguicidas químicos) y de cultivos transgénicos. Por otra parte, la agricultura familiar refiere a un tipo de agricultura ecológica basado en la dirección y la administración familiar. La agricultura familiar es el sistema de agricultura predominante en regiones pobres de América Latina y el Caribe, representando aproximadamente el 80 % de la producción agrícola. De este modo, el desarrollo de métodos eficientes de agricultura/ecológica familiar resultan fundamentales para lograr la seguridad alimentaria en la región y también para mitigar los efectos negativos del cambio climático. En este contexto, diferentes avances científico-tecnológicos han impactado positivamente sobre el manejo, eficiencia y productividad de la agricultura familiar como sistema de cultivo no sólo sustentable sino también eficiente, entre los cuales se destacan el desarrollo de mini-invernaderos, variedades mejoradas obtenidas a través de técnicas de mejoramiento genético convencional (selección a campo), trampas artesanales para la captura de insectos plagas, etc. Diferentes tecnologías/metodologías como las anteriormente citadas han sido ajustadas y validadas a partir de procesos de experimentación participativa con el objetivo de estudiar cuales son las condiciones de la zona que mejor se adaptan al tipo de cultivo y de incrementar la productividad de sistemas de cultivos sustentables.

DNA Sequence: TAC-GTG-TTA-GTC-TAA-GAA-ACT

A. 1- mRNA: UAC-GUG-UUA-GUC-UAA-GAA-ACU

    2- Amino acid sequence (5'3' Frame): Tyrosine-Valine-Leucine-Valine-stop codon-Glutamic acid-Threonine (abbreviation: YVLV-ET)

B. 1- mRNA: UAC-UGU-UAG-UCU-AAG-AAA-CU

   2- Amino acid sequence (5'3' Frame): Tyrosine-Cysteine-stop codon-Serine-Lysine-Lysine (abbreviation: YC-SKK)

Explanation:

Transcription is a cellular mechanism where a specific sequence of a DNA strand is used as template to synthesize an RNA molecule, often a messenger RNA (mRNA) molecule that is subsequently utilized to create an ordered sequence of amino acids (i.e., a protein) by a mechanism referred to as translation. In RNA, uracil (U) always replaces thymine (T) bases. During translation, the mRNA is "read" according to the genetic code which associates the DNA sequence to the amino acid sequence in the polypeptide chain. For such purpose, each triplet of nucleotides or 'codon' in the mRNA specifies one aminoacid or one-stop codon (stop codons are UAA, UAG, UGA).

Answer:

yes, humans are the best example of interdependent relationships. unlike most organisms, humans have a pattern of staying around the same group of people and forming habits around those people while also using them codependently. not only do humans rely heavily on each other, but also on pets, that are often on the same level of dependency for emotional support as other humans. these interdependent relationships are unlike any other organism.

Explanation:

It is definitely true that humans have interdependent relationships with other organisms.

An organism may be defined as a living thing made up of one or more cells and able to carry on the activities of life.

Humans are surrounded by a variety of other organisms. These organisms are either directly or indirectly associated with humans. For example, trees give food, shade, most important oxygen to humans. Cows and buffaloes give milk, bacteria and other organisms make the soil fertile and yield high productivity of crops. Not only humans every organism in the atmosphere are interacted with others to perform all its functions.

Therefore, It is definitely true that humans have interdependent relationships with other organisms.

Answer:

White tailed deer.

Explanation:

White tailed deer is the organism for which carrying capacity is shown in the graph. the population of organism decreases after reaching its carrying capacity because of limited resources of food that is not available for organisms which leads to the death of organism. The population exceeded its carrying capacity because of favourable condition such as availability of more food. The population decrease after it exceeded the carrying capacity due to unavailability of food to the increased population so they die and decrease occur in population.

Answer:

The niche of an organism within an ecosystem depends on how the organism responds and reacts to the distribution and abundance of these factors, and in turn how it alters the factors. For example, when resources are abundant, a population grows, although by growing, the population 

The niche of an organism within an ecosystem defines how the organism responds and reacts to the distribution and abundance of these factors, and in turn how it alters the factors.

Example of niche includes when resources are abundant, a population grows, although by growing, the population although by growing, the population provides more resources for predators.

There are two major types of ecological niches namely fundamental niches and realized niches. Fundamental niche is the entire set of conditions under which an animal (population, species) can survive and reproduce itself. Realized niche is the set of conditions actually used by given animal  species), after interactions with other species (predation and especially competition) have been taken into account.

To Sustain Life WE Need air, water, food, shelter, sanitation, touch, sleep and personal space.

Answer:  For one thing, with the increase in slope, the soil infiltration rate will decrease, which can increase the runoff amount [15–17]. For the other, the effective rainfall obtained by the soil bin will decrease as the slope increases.

Explanation:

Answer:

Maintenance can be difficult, at best, and establishing plants, though very important for slope stability, often requires implementing costly and laborious solutions for erosion control. Every time it rains, the water that flows down a slope slowly removes soil and can cause gullies to form over time, removing valuable topsoil from the landscape.

Answer:

The settling out of particles that have been taken by erosion.

The one that is not an example of an ecosystem service is creativity born from interactions with nature. The correct option is c.

An ecosystem is a geographical area in which plants, animals, and other species, as well as weather and scenery, coexist to produce a life bubble. Ecosystems comprise both biotic (living) and abiotic (nonliving) components.

Plants, animals, and other species are examples of biotic factors. A marine ecosystem, for example, contains 32% of the world's producers because water covers three-thirds of the earth's surface and provides a natural habitat for a diverse range of small and large living species and plants.

Therefore, the correct option is c. creativity born from interactions with nature.

Answer:

Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as cellular respiration.

Explanation:

The product of photosynthesis that stores the most energy is glucose.

Sugars include glucose, which is the main source of energy for all living things.

The primary sugar in your blood is called blood sugar, or glucose. Your body uses it as its primary source of energy, and it originates from the food you eat. All of the cells in your body receive glucose from your blood to be used as fuel.

Glucose, which is the chemical that generates energy to power the functions of the cell, is the primary byproduct of photosynthesis.

The primary byproduct of photosynthesis is oxygen. One glucose molecule is created from six carbon dioxide molecules and six water molecules.

Thus, glucose is the product of photosynthesis stores the most energy.

Answer:El usufructo (del latín: usus fructus, «uso del fruto»)1​ es un derecho real de goce o disfrute de una cosa ajena. El Código Civil de España define este derecho en su artículo 467 como "el derecho a disfrutar los bienes ajenos con la obligación de conservar su forma y sustancia, a no ser que el título de su constitución o la ley autoricen otra cosa" .2​ Por consiguiente, la persona titular del usufructo es mero tenedor respecto de la cosa pero no su dueño ni poseedor. Tiene la mera tenencia sobre la cosa, pero no la propiedad. Puede utilizarla y disfrutarla, es decir, obtener sus frutos o rendimientos, sean en especie o dinerarios, pero no puede disponer libremente de ella por no ostentar el derecho de propiedad sobre aquella. Es la razón de que no pueda enajenarla ni disminuir su valor sin el consentimiento del titular de la propiedad.
