Which of the following statements are true about asexual reproduction? (chose all that apply)
Asexual reproduction requires only one parent.
The offspring in asexual reproduction are clones of the parent.
The offspring in asexual reproduction are produced by mitosis.
The offspring in asexual reproduction are produced by meiosis.
Organisms like the planarian and the starfish can regrow parts of their bodies. This is known as (a) .
All forms of asexual reproduction use _________________ to grow new cells and organisms.
mitosis
meiosis
In the diagram below, which part of the diagram represents the asexual reproduction part of the cycle?
a
b
process in sexual reproduction in which male and female reproductive cells join to form a new cell
asexual reproduction
fertilization
sexual reproduction
tissue
the process whereby seeds or spores sprout and begin to grow
germination
pollination
reproduction
cellular respiration
the process of producing offspring
photosynthesis
homeostasis
germination
reproduction
When compared to organisms that utilize process A, organisms that utilize process B would most likely produce offspring with
a greater variety of genetic combinations
fewer genetic differences
more genetic combinations
more DNA within each nucleus
One of the largest and oldest organisms on Earth is located in Fishlake National Forest in Utah. Pando is an 80,000-year-old grove of aspen trees that covers 100 acres. Although it looks like a forest, DNA analysis of several of the “trees” has confirmed it is really just one huge organism. Therefore, the “trees” must have been reproduced
sexually and have genetic variability
asexually and have genetic variability
sexually and are genetically identical
asexually and are genetically identical
A human cell that contains all of the information necessary for the growth and development of a complete organism is
a sperm cell
a gamete
a zygote
an egg cell
Sexual reproduction requires _____ parent(s) and asexual reproduction requires ___ parent(s).

What is the best definition of animal adaptation?
Changes to an animal's diet.
Characteristics that help animals survive.
Characteristics of an animal's habitat.
Skills learned in order to hunt.
True or false: All animals have adaptations that help them survive in their habitat.
True

Fill in the blanks: A _________ adaptation is the way an animal acts in order to help them survive.
Physical
Behavioral

The black bear’s primary diet is fruit, nuts, honey, and berries. However, they also like to eat fish and small mammals. Their long, sharp claws make it possible to climb trees in order to reach some of their food sources. Black bears also have an extremely good sense of smell. Their long nose allows them to smell up to 20 miles away. This is 100 times better than humans can smell. The black bear’s tongue is sticky allowing them to easily eat ants, berries, and nuts. Black bears also have extremely strong legs, allowing them to move rocks and other obstacles out of their way to get to their food. SELECT ONE EXAMPLE OF THE PHYSICAL ADAPTATIONS LISTED ABOVE.
Eating nuts
Sticky tongue
Eating fish and small mammals
Moving rocks
I am a grey goose who loves to fly. Every fall when it starts to get cold, I fly south for the warmth. Once my home warms up, I know it is safe to go back home. What adaptation is this?
hibernation
mimicry
camouflage
migration
It is an example of an learned adaptation.
finding shelter
breathing
web spinning
The Venus flytrap plant lives in soil with few nutrients. The plant absorbs nutrients by trapping insects inside its leaves.
The ability of the Venus flytrap to trap insects is an example of which of the following?
Parasitism
Adaptation
Competition
Producer
Adapatation are caused by
natural selection
harsh environmets
unique organisms
evolution
Which would be an adaptation useful in a cold biome?
Being of a smaller size
Being active during the cooler times of day
Blubber/fat
Having dark fur
- Use sun's energy to make their own food
- Plants (grass)
Cattle egrets forage (feed) in fields among cattle. The egret gets easy access to flying insects stirred up by the cattle, and the cattle don't care if the egrets are there or not.
