Strong/ fit because u need exercise in order to stay fit and healthy for muscles or anything in the body
I'm afraid that is not possible since those two are very distant animals genetically since they're not part of the same species, genus nor family.
But if it was possible, you could either obtain a dog with bublebee traits or a bumblebee with dog traits for example.

Answer:
Atmospheric carbon dioxide (from animals)
Explanation:
The carbon atoms in glucose come from the atmospheric carbon dioxide molecules that are taken in by plants for photosynthesis.

The correct macthing of the organs with their organ systems is as follows.
1. Digestive system - intestines.
2. Central nervous system - brain.
3. Respiratory system - tracheal system.
4. Excretory system - bladder.
Digestive system is made up of the alimentary canal consisting of the digestive organs and the glands. Among the digestive organs, the intestines play a major role in the process of digestion. The small intestine is the site of complete digestion which is associated with the pancreas and liver. The large intestine is involved the absorption of water from the digested food and remaining waste material is stored and thrown out of the body during defecation.
The central nervous system is made up of the brain and the spinal cord. The brain makes the largest part and the functional of the central nervous system. It controls most of the activities of the body. It is made up of three parts called the cerebrum, cerebellum and medualla oblongata and is protected by the skull.
The respiratory system is divided into the upper respiratory tract consisting of the nasal cavity, pharynx and larynx, and the lower respiratory tract consisting of the trachea, bronchi, bronchioles and the alveoli. The trachea or the wind pipe is a cylindrical tube infront of the oesophagus, supported by 16-20 C-shaped hyaline cartilage. It serves as a passage for air to move in and out of the lungs.
The excretory system is made up of a pair of kidneys, a pair of ureters, an urinary bladder and an urethra. The urine produced by the kidney flows through the ureters and is collected in the urinary bladder. A spinchter (a ring of muscle) guards the opening of the bladder into the urethra and relaxes only at the time of urination under the impulse from the brain.
Answer:
Only when a microorganism has successfully established a site of infection in the host does disease occur, and little damage will be caused unless the agent is able to spread from the original site of infection or can secrete toxins that can spread to other parts of the body. Extracellular pathogens spread by direct extension of the focus of infection through the lymphatics or the bloodstream. Usually, spread by the bloodstream occurs only after the lymphatic system has been overwhelmed by the burden of infectious agent. Obligate intracellular pathogens must spread from cell to cell; they do so either by direct transmission from one cell to the next or by release into the extracellular fluid and reinfection of both adjacent and distant cells. Many common food poisoning organisms cause pathology without spreading into the tissues. They establish a site of infection on the epithelial surface in the lumen of the gut and cause no direct pathology themselves, but they secrete toxins that cause damage either in situ or after crossing the epithelial barrier and entering the circulation.
Most infectious agents show a significant degree of host specificity, causing disease only in one or a few related species. What determines host specificity for every agent is not known, but the requirement for attachment to a particular cell-surface molecule is one critical factor. As other interactions with host cells are also commonly needed to support replication, most pathogens have a limited host range. The molecular mechanisms of host specificity comprise an area of research known as molecular pathogenesis, which falls outside the scope of this book.
While most microorganisms are repelled by innate host defenses, an initial infection, once established, generally leads to perceptible disease followed by an effective host adaptive immune response. This is initiated in the local lymphoid tissue, in response to antigens presented by dendritic cells activated during the course of the innate immune response (Fig. 10.2, third and fourth panels). Antigen-specific effector T cells and antibody-secreting B cells are generated by clonal expansion and differentiation over the course of several days, during which time the induced responses of innate immunity continue to function. Eventually, antigen-specific T cells and then antibodies are released into the blood and recruited to the site of infection (Fig. 10.2, last panel). A cure involves the clearance of extracellular infectious particles by antibodies and the clearance of intracellular residues of infection through the actions of effector T cells.
