Answer:
The burning of wood and the burning of food calories produce carbon dioxide and heat. The calory burning gives energy to the body but in wood burning only wood becomes a carbon compound i.e. ash.
Explanation:
The burning of wood and the burning of calories release carbon dioxide and heat. In the body, oxygen breaks down the food calories and produces CO2 which release from the body by exhalation. The heat produced by food burning causes sweating. Oxygen also helps in burning of wood. In this way the food calory burning and wood burning are similar.
In calory burning the complex food becomes simpler and helps in tissue metabolism. In wood burning atmospheric oxygen helps in burning, and they release other gases like carbon monoxide, nitrogen to the environment which is not happening in case of metabolism. The complete burning of wood results in carbon compounds. In calories burning excess energy is stored in the form of fat. Because food calories are nothing but energy derive from different food.
Linnaeus’s work accounted for evolution.
Linnaeus did not use structural comparisons.
Linnaeus primarily used physical characteristics.
The right option is; Linnaeus primarily used physical characteristics
Some of Carl Linnaeus’s classifications of organisms are incorrect because he primarily used physical characteristics.
Carl Linnaeus, known as the father of taxonomy, was a Swedish biologist who classified organisms according to their physical characteristics. Carl Linnaeus proposed that there were three major groups, named kingdoms. These kingdoms were animals, plants, and minerals. He divided each of the kingdoms into five levels which are; class, order, genus, species, and variety. Organisms were arranged in these levels according to their traits, which include physical appearance such as body size, and shape, similarities of body structure, and way of obtaining food.
b.all recessive traits
c.1/3 dominant traits
d.2/3 recessive traits
e.none of the above
B. time
C. dimension
D. mass
the only answer is magnitude and dimension
Answer:
The correct answer will be
Marsh grass→ grasshoppers→shrew→marsh hawk.
Explanation:
The food chain is a series of steps of energy transfer in an ecosystem by eating the organism and itself being eaten.
The food chain starts from the autotrophs or producers which can synthesize the food on their own like plants, eaten by primary consumers or herbivores which feeds on autotrophs. The primary consumers itself are eaten by the secondary consumers also known as carnivores and so on. The energy is transferred in the food chain via a 10% energy rule.
The food chain in marsh starts from the Marsh grass which is eaten by the grasshoppers. These grasshoppers are eaten by the shrew which is eaten by the marsh hawk.
Thus, Marsh grass→ grasshoppers→shrew→marsh hawk is the correct answer.
