Asexual Reproduction
How many parents pass on genetic information to their offspring in asexual reproduction?
1 Parent
How many parents pass on genetic information to their offspring in sexual reproduction?
2
What are three resources needed for a plant to reach its maximum size?
Food, water + sunlight
The goal of most animal behaviors is to help them do what?
Survive and reproduce
The process in sexual reproduction in which an egg cell and a sperm cell join to form a new cell is called what?
fertilization
How do offspring produced from asexual reproduction compare genetically to the parent(s)?
Identical
How do offspring produced from sexual reproduction compare genetically to the parent(s)?
Combination of mom + dad
What are pollinators?
Insects or animals that moves/spreads pollen from one plant to another.
Ants use swarming tactics to protect their nests. What type of animal behavior is this?
Cooperative behaviors
What is the definition of inheritance?
The process of an offspring receiveing genes from its parents
Short reproduction time.
Do not need to find a mate.
Genetic variation in offspring can adapt to new/changing environments.
Why are pollinators important to plants?
Help fertilize plants and allow them to reproduce.
Attentive polar bear mothers usually give birth to twin cubs that stick by her for about two years to learn the necessary survival skills in the cold climate. What type of animal behavior is this?
Parental investment
A sequence of DNA that determines a trait and is passed from parent to offspring is called what?
Gene
What is a disadvantage of asexual reproduction?
No genetic variation.
What is a disadvantage of sexual reproduction?
Takes a long time.
Need to find a mate.
The goal of specialized plant structures is to what?
Attract pollinators so that they can reproduce.
Northern elephant seals come to shore twice a year, one to reproduce and once to shed old fur and skin during the molt. The rest of their days are devoted to two feeding trips that account for eight to ten months away and sometimes over 12,000 miles of travel. What type of animal behavior is this?
Migration
What is the definition for alleles?
A different form of a gene
What animals/plants go through asexual reproduction in question 12?
Starfish + jellyfish (also Spanish Moss)
What animals/plants go through sexual reproduction in question 12?
List 3 plant structures that attract pollinators and why.
Petals - bright colors bring attention to the flower to attract pollinators.
Nectar - provides food for some insects/animals that bring pollinators to the flower.
Scent - strong scents can attract pollinators which bring them to the flower.
Describe the behavior of Salmon and how they reproduce.
Salmon must smell and navigate to their “home river” at which they can lay eggs and those eggs can be fertilized.
What is the definition of genes? How does it affect offspring?
A gene is a sequence of DNA that is passed from parent to offspring which determines a trait. Offspring may look very similar to their parents, or very different depending on the genetic variation.
