Adult and larvae stages in complete metamorphosis feed on different foods and have different predators. In insect metamorphosis both adults and nymphs consume the same food and have similar predators. What is the difference between complete and incomplete metamorphosis based on the information above?
Complete metamorphosis gives insects a survival advantage.
Incomplete metamorphosis gives insects a survival advantage.
Different food habits in complete metamorphosis results in a short life cycle.
Similar food habits in incomplete metamorphosis results in a short life cycle.
Animals whose parents _______ tend to have many offspring at one time in order for enough to survive.
stay with them when they are young
do not stay with them when they are young
continue to feed the young
are the heat source for the young
give them constantly nurturing habits
[CHOOSE MORE THAN ONE ANSWER] Which pictures show how adult animals feed themselves? Choose all that apply.
[CHOOSE MORE THAN ONE ANSWER] One day, Ridho voluntarily wrote an article about metamorphosis for his school magazine. There are a few mistakes. Select all that apply (three).
All insects undergo metamorphosis. This is a stage of development
This diagram of a praying mantis shows the same life cycle as a butterfly
In a praying mantis life cycle, the nymph is the adult so it can lay eggs
The adult is the reproductive stage. The nymph has wings like the adult
During the egg stage, the organism is unable to move independently
Which statements are incorrect about mammals?
Most mammals reproduce by giving birth to live young.
After the offspring are born, the parents give them minimal parental care.
The female mammal has special glands. These teats produce milk.
The milk provides nutrients that help the baby grow.
After the young develop teeth, it is weaned and can eat an adult diet.
Offspring that are created by sexual reproduction...
are identical to their father
are identical to both parents
have a mix of genetic material from both their mother and father
have completely different DNA than either of their parents.
are essentially have just one set of genetic material

Plant kept in a dark place may at first grow taller than plant kept in a bright place. It can happen because ___________
The plant can make their own food (photosynthesis) without light
The plant get energy from soil to photosynthesis
The plant use the food stored in it so that the stem can grow longer
It get taller because it can absorb energy from air
The plant tissue might be damaged if directly exposed by sunlight
Most seeds do not light to germinate, because _____________
Seeds can use the food stored inside
Seeds can do photosynthesis in the dark soil
Seeds can produce light to make their own food
Seeds can do photosynthesis without light.
Seeds can be damaged if exposed by certain light wavelength
The adaptation of seeds that prevents them from germinating during unsuitable ecological conditions that would typically lead to a low probability of seedling survival is called
dormancy
germination
reproduction
primary growth
seedling
