1. Both ways of reproduction result in an offspring, but 2 organisms of opposite genders are needed for sexual reproduction and the offspring produced is similar to both parents, meaning they share some of the genes of both parents. In asexual reproduction, only one parent is needed and the offspring is identical to the parent, meaning the offspring shares the exact same genes as the parent.
2. both alleles contain genetic code for the same trait, just different versions. But recessive traits are only shown if the offspring recieves the same recessive gene from both parents, whileoffspring only need one dominant allele for it to be expressed
3. Chromosomes and alleles have genes for traits, but Chromosomes contain the genes of the offspring, while the alleles are the gene version for a specific trait.
4. Both mitosis and meiosis produce cells, but mitosis is the process to produce two identical normal cells with the same genes, while meiosis is the process to create two reproductive cells, each with 1/2 of the genes from the parent cell.
LOL, but I'm having this lesson in my science class as well, so I understand.
I believe the answers are community and population
Answer:
The correct answer is "All of these are fixed patterns".
Explanation:
Fixed action patterns are instinctive programmed responses in different species that are triggered by a specific external sensory stimulus. These stimuli are called <u>sign stimuli</u>. When the sign occurs, the animal starts a sequence of acts in response to the stimulus and continuous until the series of actions is completed. If the animal is interrupted for some reason, it continues its job from where it was interrupted; either the original stimulus is or is not present.
- A <u>chick’s gaping mouth</u> induces a feeding response in a parent bird: <em>The stimulus is the gaping mouth</em>, which <em>makes the parents</em> to instinctually respond f<em>oraging</em> more and <em>feeding</em> the chick.
- A male fruit fly <u>waves his wings</u> at a female fruit fly during courtship: In courtship, the <em>original stimulus is the presence of the female</em>. One of the <em>male´s responses actions is the wave of its wings</em>.
- A baby garter <u>snake captures and eats a slug</u>: For the baby snake, the <em>sign stimulus is the slug scent</em>. The snake then <em>responses</em> by <em>capturing and eating the slug</em>.
- A European <u>cuckoo hatchling pushes the host bird's egg</u> out of the nest: The <em>stimulus</em> for the cuckoo chick <em>is the presence of the host bird´s egg</em>. When the cuckoo bird emerges from its egg, even before it opens its eyes, it <em>pushes the host out of the nest.</em>
