Do some cows some (acquire/inherit) traits that make them have more muscles compared to other cows.
just olya [345]

Answer:

Explanation:

Molecular biology has enabled the identification of the mechanisms whereby inactive myostatin increases skeletal muscle growth in double-muscled (DM) animals. Myostatin is a secreted growth differentiation factor belonging to the transforming growth factor-β superfamily. Mutations make the myostatin gene inactive, resulting in muscle hypertrophy. The relationship between the different characteristics of DM cattle are defined with possible consequences for livestock husbandry. The extremely high carcass yield of DM animals coincides with a reduction in the size of most vital organs. As a consequence, DM animals may be more susceptible to respiratory disease, urolithiasis, lameness, nutritional stress, heat stress and dystocia, resulting in a lower robustness. Their feed intake capacity is reduced, necessitating a diet with a greater nutrient density. The modified myofiber type is responsible for a lower capillary density, and it induces a more glycolytic metabolism. There are associated changes for the living animal and post-mortem metabolism alterations, requiring appropriate slaughter conditions to maintain a high meat quality. Intramuscular fat content is low, and it is characterized by more unsaturated fatty acids, providing healthier meat for the consumer. It may not always be easy to find a balance between the different disciplines underlying the livestock husbandry of DM animals to realize a good performance and health and meat quality.

Developing a new vaccine takes about 5-10 years. So how is it possible to develope Corona vaccine so quickly?​
rusak2 [61]

Answer:

vaccines were designed by using new technologies (i.e., RNA-based vaccines and adenovirus-based vaccines)

Explanation:

RNA-based vaccines are vaccines based on the delivery of specific messenger RNA (mRNA) sequences that are capable of encoding only one viral protein, thereby preventing the complete viral cycle/replication. Subsequently, this protein is recognized by the immune system that generates memory immunity by synthesizing specific antibodies against this protein (in this case, the spike S protein). On the other hand, adenovirus-based vaccines are vaccines designed by inserting a transgene cassette into an adenovirus which is used as vector to produce one specific viral protein inside the host. Like mRNA vaccines, this antigenic viral protein is then recognized by the immune system in order to produce antibodies against a defined protein epitope, thereby producing memory immunity.

The end result of metabolism is a cellular energy unit called
stepladder [879]


The best answer is ATP (Adenosine triphosphate).

Metabolism is a term referring to the overall processes by which  energy is obtained by an organism. In man it begins with the digestion process, and ends with cellular respiration.

Food molecules are broken down into their monomer units through the digestive process. Carbohydrates are broken into glucose units. Glucose is taken in by cells and used in cellular respiration to produce ATP, which is the form of energy that cells use.

Cellular respiration involves three stages namely glycolysis , Krebs cycle and electron transport chain.  From one molecule of glucose, the number of ATP molecules generated through cellular respiration  is 36 to 38 molecules.
