Answer 12

Traits in a species that can be measured, not all people have it, varies

Question 13

What are some examples of continuous characteristics

Answer 13

Height, weight, shoe size

Question 14

Whats asexual reproduction

Answer 14

It occurs when only one parent supplies the info to the offspring. The genetic material and the characteristics between the parents and offspring are identical.

Question 15

What are some examples of asexual reproduction are there in our world

Answer 15

fungi and bacteria

Question 16

Does asexual reproduction include gametes zygotes

Answer 16

no

Question 17

Whats sexual reproduction

Answer 17

IT occurs when two parents supply genetic material to the offspring. The offspring and parents are not the exact same and will carry a combination of characteristics from both parents. Gametes come together to form zygote

Question 18

What happens when the gametes meet together

Answer 18

they form a zygote

Question 19

Whats gametes

Answer 19

sperm and egg

Question 20

Whats a zygote

Answer 20

When the sperm and egg come together

Question 21

With sexual reproduction do sibling vary in genetics and characteristics

Answer 21

Yes, except for twins

Question 22

What are the 3 types of diversity

Answer 22

Ecosystem, species and genetic

Question 23

Whats ecosystem diversity

Answer 23

the variations in ecosystems within a geographical location and its overall impact on human existence and the environment.

Question 24

What is species diversity

Answer 24

the number of different species present in an ecosystem and relative abundance of each of those species.

Question 25

What is genetic diversity

Answer 25

the range of different inherited traits within a species.

Question 26

What are some examples of ecosystem diversity

Answer 26

Within a mountain range: rivers, streams, mountains, hills, forests, snow

Question 27

Examples of species diversity

Answer 27

Within a mountain range: Fish, mountain goats, bears, gophers

Question 28

Examples of genetic diversity

Answer 28

Within a mountain range: Variations of flowers, different breeds of fish, grizzly bear vs. black bear

Question 29

What are structural adaptaions

Answer 29

How an animals body looks so it can function in its environment

Question 30

What are behavioural adaptations

Answer 30

Something an animal does in a response to a stimulus to survive

Question 31

Examples of structural adaptaions

Answer 31

Giraffes long neck, camouflage fur, ducks webbed feet

Question 32

Examples of behavioural adaptations

Answer 32

Hibernations, migrations, storing food for winter

Question 33

How does sexual reproduction in plants work

Answer 33

Sexual reproduction in plants involves gametes as well, male gametes and female gametes joining, during fertilization, to produce a zygote and then an embryo.

Question 34

What does pollen contain

Answer 34

male gametes(sperm)

Question 35

Where is pollen found

Answer 35

on the stamen

Question 36

What do ovules contain and where are they found

Answer 36

They contain female gametes(eggs) and are found in the pistil

Question 37

When does pollinations occur?

Answer 37

When pollen is transferred from the anthers of the stand to the stigma of the pistil

Question 38

What is cross pollination

Answer 38

pollen from one plant is carried to the stigma of another plant by wind, water or animals (bees or butterflies).

Question 39

When does cross fertilization occur

Answer 39

when a grain of the pollen forms a long tube (pollen tube), which grows down the style into the ovary.

Question 40

What is asexual reproduction in plants

Answer 40

part of the parent plant is used to generate a new plant. The new plant is genetically identical to the parent plant from which the stock has been taken.

Question 41

Whats mitosis

Answer 41

Cell duplication: the process where one cell operates an becomes two separate cells

Question 42

Whats binary fission

Answer 42

When a cell duplicates its contents including its nucleus and other organelles. It then splits into two cells with each one being identitcal.

Question 43

Whats asexual spore production

Answer 43

Spores form then divide to produce offspring

Question 44

Define budding

Answer 44

ghthe parent organism produces a bud (a smaller version of itself), whicheventually detaches itself from the parent and becomes a self-sufficient individual - identical to the parent.
