Answer:
1. Pelvis is wider in females due to it is an anatomical feature that allows the childbirth
2. A study aimed at determining if the size of the pelvis shows association with problems during childbirth
3. Females with smaller pelvis frequently have problems during childbirth
4. Populational biases in the data regarding ethnicity, age, etc
Explanation:
A hypothesis is a proposed explanation for a given phenomenon from the real world. A scientific hypothesis needs to be tested by experimentation or observational procedures. A good hypothesis must fulfill two key requirements 1- it must be-testable, i.e., capable of being proved by using the scientific method, and 2-falsifiable, i.e., it must have a possible negative answer.
Answer:
The correct answer is - aerobic cellular respiration, oxygen, anaerobic cellular respiration, energy, lactic acid and muscle fatigue.
Explanation:
The most common type of cellular respiration is aerobic cellular respiration which takes place in the condition where enough amount of oxygen is available that provides energy to the body.
In absence of enough amount of oxygen the anaerobic cellular respiration, when an individual exercise intensely his body not able to provide enough amount of oxygen to the cells so, therefore, perform anaerobic respiration to produce energy however this cause muscle fatigue due to a byproduct known as lactic acid.
Answer:
A
Explanation:
I chose this answer because asexual needs only 1 parent but sexual reproduction HAS TO HAVE 2
Answer:
D. There is no enough oxygen in the culture fluid
Explanation:
The cells in the test tube need to carryout one of the important metabolic processes of living organisms - respiration. The process involves the breakdown of glucose to generate energy for other metabolic processes in the cell.
Respiration can be carried out in the presence of oxygen (aerobic) or in the absence of oxygen (anaerobic). Human cells are primarily aerobic but can carryout respiration anaerobically in the presence of inadequate oxygen.
For aerobic respiration, glucose is broken down in the presence of oxygen to produce carbon-dioxide, water and energy in the form of ATP:
<em>In the absence of oxygen, the glucose becomes converted to lactic acid and a smaller amount of ATP is produced as compared to aerobic respiration.</em>
<em>Hence, lactic acid gradually builds up in the absence of oxygen due to anaerobic respiration.</em>
The correct option is D.
