1 you run out of fuel 2 it takes a long time 3 it’s hard to get back 4 the conditions are constantly changing making it harder to predict what could happen. Look at Apollo 12 as a example
Its dead plants and animals
Soaring and gliding birds like eagle, vulture, albatross, sea gulls etc are efficiently adapted to utilize the air currents in their flight.
Explanation:
The soaring flight and gliding movements are special adaptation developed by birds to meet the challenge of increasing turbulent air current.
Birds have the extraordinary skill of flying smoothly and effortlessly even at very high altitudes
Birds soar by using thermal and dynamic soaring techniques.
Gliding movements help the birds to deflect the wind downward which helps to lift their bodies in the air. They do not flap their wings during gliding but just dive straight into the air which helps to increase their speed.
The adaptation of the bird’s structure with very light but strong bones on their wings helps to soar and glide in the air.
Answer: B. Lungs
Explanation:
The lungs are the only organ in the body that can float on water.
Answer:
This question is incomplete, the complete part is asking to identify the variables of the experimental statement i.e. dependent and the independent variables.
Independent variable: different amounts of time light is on
Dependent variable: Number of eggs laid by chicken
Explanation:
In a scientific experiment, variables, which are factors that can be altered, are used. These variables are independent and dependent variables.
An independent variable is that variable that is subject to manipulation or control by the experimenter in order to bring about a change in the dependent variable. For this experiment, the independent variable is the DIFFERENT AMOUNT OF TIME LIGHT IS ON.
On the other hand, a variable is said to be dependent if it is the measurable or responding variable. The response of the dependent variable is dependent on the independent variable. In this experiment, the dependent variable is the NUMBER OF EGGS LAID BY CHICKENS. The number of eggs laid (dependent variable) is dependent on the amount of time light is on (independent variable).
