Answer:

Las plantas son las primeras, los herbívoros son los segundos, los carnívoros pertenecen al tercer nivel trófico.

Explicación:

Las plantas son los primeros niveles tróficos debido a la producción de alimentos mediante el proceso de fotosíntesis. Aquellos organismos que se alimentan de plantas se consideran consumidores primarios y segundo nivel trófico. Aquellos organismos que se alimentan de consumidores primarios se consideran consumidores secundarios así como de tercer nivel trófico. El consumidor terciario se alimenta del consumidor secundario y cae en el cuarto nivel trófico.

Answer:

disturbance plays in competition.

Explanation:

Fire-dependent pitch pine trees (Pinus rigida) is replaced by black locust (Robinia pseudoacacia) because of disturbance that occurs in the environment naturally. When disturbances occur naturally, they provide conditions that favor the success of different species over the native organisms. The native organisms are vanished from that ecosystem due to changing of environmental conditions and other organisms settle there which can survive in that environment.

Answer:

B

Explanation:

Hunter-gatherer is the term that best describes the first human communities in which people obtained food by hunting, fishing, and gathering berries. Thus, the correct option is B.

Hunting may be defined as an activity that involves the killing or capturing of animals or any other organisms for the purpose of food.

Post-industrial is the time after industrialization. Agricultural is an activity that is directly related to crop and crop production. Domesticated may be defined as the process that adapted over the course of time from a wild to the natural state.

Therefore, the correct option for this question is B.

Answer and explanation:

Water volume and blood pressure are directly linked with one another, and the regulation of these parameters is fundamental to maintain homeostasis and make life possible.

Hyponatremia is a condition in which sodium levels in blood are below normal (normal being between 135-145 mEq/l). When sodium concentration decreases to this pathological point, the blood becomes "diluted" because of the lack of this vastly important ion. To compensate the dilusion produced in blood, water will start moving from this tissue to enter the cells -thanks to a phenomenom called 'osmosis'-, swelling the cells and developing into a life-threatening condition. As a result of the influx of water, the volume levels in the extracellular compartment (with includes blood) will decrease, leading to a blood pressure decrease as well.

The tRNAs contain I sound that base pair A C U advantageous to the species rabbit.

A form of RNA molecule called transfer ribonucleic acid (tRNA) aids in the translation of a messenger RNA (mRNA) sequence into a protein.

Translation, which creates a protein from an mRNA molecule, uses tRNAs at particular locations on the ribosome. A protein's amino acid composition is determined by codons, which are three-nucleotide mRNA sequences.

Every codon corresponds to a distinct amino acid, and every codon is accepted by a particular tRNA. The three hairpin loops that make up the tRNA molecule's characteristic folded structure give it the appearance of a three-leafed clover.

Therefore, The tRNAs contain I sound that base pair A C U advantageous to the species rabbit.

Answer:

TRUE

Explanation:

The Acetylcholine neurotransmitter is released from the presynaptic cell by the process of exocytosis.

Once the molecule is in the intercellular space, it moves forward the postsynaptic membrane to join its receptor in the motor plate.

Once the joining has occurred, the receptor acquires a channel shape allowing the ion transference that will make possible the modification of the action potential. Ions traffic will consist of the pass of sodium and calcium to the interior of the cell and potassium to the exterior. Quantitatively, the interchange Na-K is the most significant.

K+ follows a concentration gradient, while Na+ follows an electrochemical gradient. The interchange results in an increase of positive charges in the interior of the muscular cell.

Whenever there is a sufficient number of Acetylcholine receptors are active, the depolarization threshold of the motor endplate is exceeded. This activates an action potential that extends to the rest of the muscle membrane.

Answer:

1/4 or 25%

Explanation:

Let us assume that the fruit color trait in the tomato is represented by R and r. The dominant color red would be represented by R while the recessive color yellow would r.

If a true-breeding red fruit tomato (RR) is crossed with a true-breeding yellow fruit tomato (rr), the F1 would be thus:

             RR    x    rr

          Rr   Rr   Rr   Rr

Since R is dominant over r, all the F1 offspring would produce red fruits with the genotype Rr.

At F2:

               Rr    x    Rr

           RR   Rr   Rr   rr

RR and Rr = red

rr = yellow

Hence, the proportion of the F2 offspring expected to be yellow would be 1/4 or 25%.

Explanation:

An information system can be defined as a set of components or computer systems, which is used to collect, store, and process data, as well as dissemination of information, knowledge, and distribution of digital products.

Generally, it is an integral part of human life because individuals, organizations, and institutions rely on information systems in order to perform their duties, functions or tasks and to manage their operations effectively. For example, all organizations make use of information systems for supply chain management, process financial accounts, manage their workforce, and as a marketing channels to reach their customers or potential customers.

Additionally, an information system comprises of five (5) main components;

1. Hardware.

2. Software.

3. Database.

4. Human resources.

5. Telecommunications.

Hence, an information system interacts with the overall system by receiving data in its raw forms and information in a usable format.

In this scenario, Mother Goose Computing, Inc. are currently updating several of their systems. For the genomics division, it's planning to replace the old system by the new one all at once. Thus, this is called a direct conversion.

Direct conversion can be defined as a process which typically involves the establishment and implementation of a new system followed by an immediate discontinuation of the old system all at once. Thus, on a particular date and time, the old system would be discontinued while the new system is immediately adopted for use in the particular organization.

Answer:

Binding taking place at the receptor site

G protein activates in the cell membrane

Conversion of GDP → GTP

Activation of adenylate cycles

Cyclic production of AMP → ADP

Initiation of the desired reaction in regard to the original message

Cyclic restoration of AMP → ATP

Explanation:

The description of the mechanism:

Right off the bat, epinephrine attaches to a molecule called a receptor (beta-adrenergic protein).

G protein, which is found on the inner side of the plasma membrane, is activated when epinephrine binds to it.

The GDP-carrying Alpha subunit of G protein is isolated during activation. After that, the GDP is translated to GTP.

Adenylate cyclase is then activated by GTP.

The only enzyme that can catalyze the transformation of ATP to CAMP is adenylate cyclase (Cyclic adenosine monophosphate). As a result, the CAMP molecule (secondary messenger) is produced.

CAMP stimulates protein kinase A, and the cycle repeats till the glycogen phosphorylase enzyme is triggered.

After that, the cyclic amp is brought back and restored.

Answer:

- Parallel arrangement of collagen fibers: Dense regular connective tissue (CT)

- Transports oxygen and hormones: Bood

- Contains chondrocytes: Cartilage

- Stores minerals: Bone

- Random arrangement of collagen fibers: Dense irregular connective tissue (CT)

- Cushions and insulates: Adipose tissue

Explanation:

The dense regular connective tissue (CT) is a type of connective tissue composed of collagen fibers arranged in a parallel pattern which provides a strong association between tissues (e.g., tendons and ligaments). Conversely, in dense irregular connective tissue, collagen fibers are not arranged in parallel bundles (e.g., the dermis in the skin and lamina propria in the gastrointestinal tract). Cartilage is a type of flexible connective tissue composed of chondrocytes, the unique type of cells in cartilage tissues. Chondrocytes are responsible to produce and maintain the collagen extracellular matrix (ECM) which is composed mainly of collagen and proteoglycans (proteins coated with sugar molecules). Bone is a type of connective tissue composed of cells (i.e., osteoblasts, bone lining cells, osteocytes, and osteoclasts), fibers and ground substance. Bones have many functions including, among others, store minerals (calcium and phosphate), protect internal organs, allow movement, provide internal support, etc. Blood is a type of connective tissue (because blood has a matrix) whose main function is to transport oxygen (O2) and essential substances (e.g., nutrients, hormones, etc) to the tissues, and carbon dioxide (CO2) from the tissues to the lungs. Blood contains two different types of cells: red blood cells (i.e., erythrocytes) and white blood cells (i.e., leukocytes). Finally, adipose tissue is a special type of connective tissue in the subcutaneous layer that helps to cushion and insulate the body (providing insulation from heat and cold). Adipose tissue is composed mostly of adipocytes, which are cells that store energy in the form of lipid molecules.
