NO SCAM FILES!!! Hey! i need help! Can you help me with this?? 30 points and brainlest! For each scenario below, list the body systems involved and their function during the specific activity.

Regulation / Homeostasis
You get too hot or too cold:

Your diaphragm expands and contracts so you can breathe:

Nutrient Absorption
The reactants needed for cellular respiration are taken in and transported to your cells:

Defense from Illness
A pathogen enters your body through a cut:

Defense from Injury
A bunny is running away from a wolf:

Your hand gets too close to a flame:

Reproduction
A woman’s body prepares for a pregnancy:

A woman’s body prepares for a birth:

d. in sexual reproduction, offspring have more chromosomes than

either parent.

asexual reproduction results in offspring which are genetically the same as the parent organism (not counting a rare mutation). sexual reproduction produces a random mixture of the genetics derived from both parents

explanation:

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
