Q6: A
Q7:D
Q8:C
Reasoning
Q6: Based on all the other questions talking about common ancestors I deduced that to find a “common” ancestor they need to find things that are the same.
Q7: All arthropod have a exo skeleton for example a lobster or crab. They all have a head, abdomen and thorax for example ants. They all have legs with joints for example a spider.
Q7:So bones are traveled down by ancestors so the types of bones stay the same but natural selection has changed them to better fit their environment.
Answer:
giraffes necks consists a tall bone like structure called notochord which gives support to the skeletal system like how do we have backbone
Answer:
Breaking down a burger in the stomach.
Explanation:
Basal metabolic rate (BMR) also known as resting metabolic rate (RMR) can be defined as the amount of calories that is required to keep the human body to function properly and perfectly at rest.
This ultimately implies that, basal metabolism is the minimal amount of calories or energy that is required by an individual for maintaining vital functions such as blood circulation, keeping the body warm and respiration while fasting or in a complete mental and physical rest.
Some of the factors that affects the basal metabolism rate (BMR) in humans are height, weight, age, starvation or fasting, thyroxine, fever, stress, malnutrition and growth.
Hence, breaking down a burger in the stomach is a body function that would contribute to BMR.
D) individual birds with the mutation are more likely to survive & reproduce than birds without the mutations.
This is because the mutation is increasing their ability to catch and eat insects, thus increasing their chances of survival. Due to natural selection, birds with this mutation are favored because of their environment and they will most likely survive.
