Explanation:
All animals are in one kingdom (called Kingdom Animalia); all plants are in another (Kingdom Plantae). ... Other systems have six or more kingdoms. Species are the smallest groups. A species consists of all the animals of the same type, who are able to breed and produce young of the same kind.
Answer:
Choloroplast
Explanation:
The choloroplast hosts the enzymatic machinery that carries out photosynthesis. These proteins are embedded in the thylakoid membranes of the chloroplast. Of these proteins PSII and PSI contain chlorophyll molecules.
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.
Answer:
birth rate and death rate
Monosaccharides<span> (e.g. glucose) and disaccharides (e.g. sucrose) are relatively small molecules. They are often called sugars. Other carbohydrate molecules are very large (polysaccharides such as </span>starch<span> and cellulose).</span>
