What is respiration?Inhalation:
On inhalation, the pressure in the alveoli is high, hence the Oxygen diffuses to the nearby blood through the membrane.
Exhalation:
It is the process in which a person releases the air collected in the lung. During exhalation, the pressure in the alveoli is low, hence the carbon dioxide present in the blood is diffused out into the alveoli.
Therefore, the expandable structure of alveoli helps the respiratory system to follow its function.

Peptic ulcers are caused by damage to the wall of the stomach by the acids that help digest food.
This can be caused by the failure of
A. tight junctions
B. adhering junctions
C. gap junctions
D. plasmodesmata
E. adhering and gap junctions
Peptic ulcer disease can be caused by the failure of tight junctions. Thus, the correct option is A.
What is Peptic ulcer disease?Peptic ulcer disease may be defined as a circumstance in which bitter and painful sores or ulcers evolve in the lining of the stomach or the first part of the small intestine which is the duodenum.
A tight junction is responsible for lining the wall of the intestine or stomach. It helps in the prevention of the passage of digestive enzymes through the space between adjacent locations inside the stomach or small intestine.
If this junction breaches, it results in damage to the wall of the stomach by the acids that help digest food and causes the peptic ulcer disease which is infected by a bacterial organism known as Helicobacter pyroli.
Therefore, it is well described above.

Greater force of contraction, volume of blood ejected, and cardiac output result in aerobically trained individuals with greater stroke volume compared to untrained individuals
What increases stroke volume?A greater force of contraction consequently increases the volume of blood ejected with each systole (Systolic Volume). Increasing the stroke volume also increases, as a consequence, the cardiac output (CO = VS x HR).
With this information, we can conclude that greater force of contraction, volume of blood ejected, and cardiac output result in aerobically trained individuals with greater stroke volume compared to untrained individuals

3. Provide a possible explanation as to why the incidence of basal and squamous skin cancer is so high.
4. Using breast cancer as an example, calculate the percentage of survival for this cancer type.
1. Breast cancer is the most prevalent type of cancer on the list, with 290,560 new cases anticipated in the US in 2022. Prostate cancer and lung cancer are the next most prevalent malignancies.
What is cancer?Cancer is a condition when a few of the body's cells grow out of control and spread to other bodily regions. Since the human body contains billions of cells, cancer can develop practically everywhere.
2. Skin cancer: More people than any other type of cancer develop skin cancer. Additionally, it has the highest rate of recovery from cancer. According to the American Academy of Dermatology, the survival rate for skin cancer is about 100% if it is found early.
3. As people age, their risk of developing basal and squamous cell skin cancer increases. This is most likely due to the accumulation of solar exposure over time. However, younger people are also developing these cancers at an increased rate, most likely as a result of their increased exposure to the sun.

In a quadrat that is 0.5m along each side, you count 3 daisy
plants and 25 grass plants. The whole lawn you are sampling
is 5m long and 4m wide. Calculate the number of daisy plants
and grass plants in the whole lawn. Show your working
clearly.
Answer:
Interdependence is a key concept in ecology. Whilst this can be taught theoretically, some practical fieldwork greatly enhances pupils’ understanding. Almost certainly the fieldwork would entail looking at plant abundance and distribution and, of course, some work with quadrats!
A quadrat is a simple device for marking out a small area. For young children at primary school the quadrat is often a convenient way of focusing a pupil’s attention on a particular small area. At secondary level, pupils should understand how quadrats can be used to sample a larger area. By recording information from a number of quadrats placed within a larger study area, they can obtain a representative sample of the whole area, which may be too big to describe in full.
This article describes how quadrats can be used to help pupils at lower secondary level estimate the relative abundance of plant species. All the information given here refers to frame quadrats. (Point quadrats can be tedious and difficult for pupils to use and are probably best avoided at this level.
