Answer:

The first alligator ancestors evolved about 245 million years ago.

Explanation:

The first alligator ancestors evolved about 245 million years ago due to change in the environmental condition.  crocodilians appeared about 80 million years ago during the Cretaceous period. Modern alligators has experience less changes which is closely related to their ancient ancestors and look much like to their relatives that exists about 80 million years ago. The main reason for the change in the body structure of alligator is due to change in environmental condition.

The evolution of alligators can be analyzed by sequencing samples of different species and then producing a bioinformatic analysis.

Evolution means descendence with some class of modification in offspring (phenotypic, genetic, etc).

In conclusion, the evolution of alligators can be analyzed by sequencing samples of different species and then producing a bioinformatic analysis.

Answer:

b. heat energy

Explanation:

Water, which is able to exist in three different states moves from one form to another. Water can move from the ocean to the atmosphere via a process called EVAPORATION. During the process of evaporation, the sun plays a major role by supplying the HEAT ENERGY required to change water from its liquid form in the ocean to its gaseous form in the atmosphere.

Water cycle of the earth helps ensure that water is not lost in any of its forms. Liquid water stored in the ocean gets evaporated as a result of heat energy into the atmosphere as water vapour.

Answer:

Biological energy conversion in mitochondria is carried out by the membrane protein complexes of the respiratory chain and the mitochondrial ATP synthase in the inner membrane cristae. Recent advances in electron cryomicroscopy have made possible new insights into the structural and functional arrangement of these complexes in the membrane, and how they change with age. This review places these advances in the context of what is already known, and discusses the fundamental questions that remain open but can now be approached.

Mitochondria are the powerhouses of the cell. In all eukaryotes that do not depend on photosynthesis, the mitochondria are the main source of adenosine triphosphate (ATP), the energy-rich compound that drives fundamental cell functions. These functions include force generation (for example, in muscle contraction and cell division), the biosynthesis, folding and degradation of proteins, and the generation and maintenance of membrane potentials. ATP is produced on a massive scale in the human body, amounting to 50 kg per day in a healthy adult, but considerably more in a long-distance runner. ATP is generated by the mitochondrial ATP synthase from ADP and phosphate ions. These are the products of ATP hydrolysis at the sites where energy is needed in the cell. Apart from cellular respiration and ATP synthesis, mitochondria have numerous other essential functions, including the production of NADH and GTP in the citric acid cycle, the biosynthesis of amino acids, heme groups and iron-sulfur clusters or the synthesis of phospholipids for membrane biogenesis. They also act in calcium signaling [1], stress responses [2] and generally as cellular signaling hubs [3]. Not surprisingly, mitochondria play a fundamental role in human health. Mitochondrial dysfunction is the cause of severe, often maternally inherited diseases. Moreover, mitochondria are deeply implicated in apoptosis and ageing [4].

In many respects, mitochondria resemble α-proteobacteria, from which they are thought to have originated by endocytosis some 1.6 billion years ago. The most striking evidence of this evolutionary relationship is the close homology of bacterial and mitochondrial respiratory chain complexes. Mitochondria have their own genetic system, which uses a distinct DNA code that differs both from that of their bacterial ancestors and their eukaryotic hosts [5]. They have their own protein translation machinery, complete with ribosomes, tRNAs and associated protein factors that more or less resemble those of their bacterial ancestors. Very recently, the first high-resolution structure of a mitochondrial ribosome, determined by single-particle electron cryomicroscopy (cryo-EM), has revealed a fascinating patchwork of similarities to and differences from bacterial ribosomes [6]. Nevertheless, mitochondria make surprisingly little use of their specialized protein production machinery. In the course of evolution they have transferred up to 99 % of their genes to the nucleus. Today, the vast majority of mitochondrial proteins are produced in the cytoplasm and imported into the organelle by an elaborate set of protein translocases [7]. In humans, only 13 mitochondrial proteins are organelle-encoded, all of them central, hydrophobic subunits of respiratory chain complexes or of the ATP synthase.

Mitochondria are highly dynamic [8]. In the cell, they form a tubular network that constantly changes by division and fusion (Additional file 1). Both processes are accomplished by multi-component molecular machineries that include a number of dynamin-related GTPases [9, 10]. When mitochondria are isolated from cells, the network breaks up into fragments that spontaneously reseal. Isolated mitochondria are fully competent for respiration and ATP synthesis [11]. They maintain their membrane composition, organization and membrane potential, as well as the ability to fuse [12] and to import proteins [7]. We owe much of what we know about mitochondria and how they work at the molecular level to in vitro studies with isolated mitochondria, or even mitochondrial membrane fractions, which still carry out oxidative phosphorylation and ATP synthesis [13].

The composition of mitochondrial membrane consists of several proteins and phospholipids.

The composition of a eukaryotic cell membrane comprises of phospholipids, proteins, carbohydrates and cholesterol or sterols.

Answer:

Due suitable environment and high productivity.

Explanation:

More fish are supplied by fish farming rather than from traditional because farms are build in order to harvest more fish by providing suitable environment to the fish. In transitional ways, fish are caught in nets from the rivers by local people for theirselves and the extra will sold in the market. In rivers there are less number of fish which does not meet the requirements of people so that's why commercial farming of fish can be done.

Answer:

- Célula >> unidad básica y funcional de todos los seres vivos

- Nutrición >> proceso de toma de nutrientes del medio ambiente  

- Reproducción >> proceso de replicación con el fin de perpetuar la especie

- Respiración >> proceso de intercambio gaseoso en organismos superiores  

- Adaptación >> mecanismo por el cual los organismos se ajustan a su ambiente

Explanation:

Un mamífero (por ejemplo, un perro) es un organismo multicelular compuesto por diferentes tipos de células especializadas las cuales se asocian para formar tejidos, que a su vez se asocian para formar órganos y finalmente sistemas de órganos. El sistema respiratorio está compuesto por las vías aéreas y los pulmones. Durante el proceso de respiración se produce el intercambio gaseoso de oxígeno (O2) y dióxido de carbono (CO2) entre los pulmones y la sangre. El oxígeno obtenido mediante la inspiración pasa de los alvéolos pulmonares a la sangre para llegar a cada célula del cuerpo, mientras que en cada expiración se elimina dióxido de carbono en el sentido inverso. La nutrición es el proceso de toma de nutrientes mediante el cual el organismo obtiene energía y materia de su ambiente. Durante este proceso, el sistema digestivo incorpora alimentos que posteriormente son descompuestos en moléculas simples conocidas como nutrientes las cuales son absorbidas para finalmente pasar a la sangre y así llegar a cada célula del cuerpo. La reproducción consiste en el mecanismo mediante el cual una especie se asegura su continuidad a través del tiempo. Los órganos reproductores masculino y femenino están encargados de producir células sexuales, es decir, gametos masculinos (espermatozoides) y gametos femeninos (óvulos) que se unen durante el proceso de fertilización para dar lugar a un cigoto que se desarrollará hasta formar un organismo adulto. Finalmente, la adaptación se refiere al mecanismo por el cual un organismo se ajusta a su ambiente. A nivel de especie, la adaptación es una consecuencia del proceso evolutivo por el cual aquellos organismos que se ajustan mejor a su ambiente tienen más chances de sobrevivir y reproducirse, teniendo por lo tanto más chances de transmitir sus genes a la siguiente generación.

Explanation:

It occurs when an odor binds to a receptor within the nasal cavity, transmitting a signal through the olfactory system.2 Glomeruli aggregate signals from these receptors and transmit them to the olfactory bulb, where the sensory input will start to interact with parts of the brain responsible for smell identification, memory, and emotion.3

There are many different causes for alteration, lack, or disturbance to a normal sense of smell, and can include damage to the nose or smell receptors, or central problems affecting the brain. Some causes include upper respiratory infections, traumatic brain injury, and neurodegenerative disease.

Answer:

position effect

Explanation:

Position effect refers to the consequences on the expression of a gene/transgene when it is inserted into a new genomic location, thereby explaining how transgene's behavior is affected by its genomic location. The differences in expression of the inserted gene/transgene are generally due to its proximity to regulatory sequences (e.g., enhancers). Species with larger genomes have many genes as well as long intergenic regions where heterochromatin may spread stochastically (randomly) in order to switch on/off the gene expression, thereby resulting in unstable phenotypes.
