please help I'm stuck!!!​

a)

Actual diameter = 0.007 mm

Diameter of scaled diagram = 2.3 cm = 23 mm

Formula to use:

Magnification = scaled dimension/actual dimension

Magnification = 23/0.007

Magnification = 3285.714... → x3286

b)

Red blood cells (RBCs), otherwise known as erythrocytes, don't have nuclei and organelles such as mitochondria, are smaller than WBCs and have a biconcave disc shape ideal for purpose

c)

i.

RBCs transport oxygen inhaled into the lungs around the body to all tissues and organs

ii.

RBCs are void of organelles so they are maximally packed with haemoglobin to bind and transport oxygen;

The biconcave disc shape is ideal for flowing through the blood vessels, particularly the capillaries, optimising them for transporting oxygen;

The small size also helps in being able to circulate the vasculature effectively and successfully

Answer:

Autotrophs is the answer

Example : plants

Plants and some bacteria (e.g., cyanobacteria) carry out autotrophic nutrition, synthesizing their own organic molecules using light or inorganic substances.

Organisms that carry out autotrophic nutrition are capable of producing their own organic compounds and energy sources using inorganic substances. One example of an organism that performs autotrophic nutrition is plants. Plants possess specialized structures called chloroplasts that contain chlorophyll, a pigment responsible for capturing sunlight energy.

Through the process of photosynthesis, plants convert carbon dioxide and water into glucose, a form of stored energy. This energy is then used by the plant for growth, development, and other metabolic processes. Additionally, some bacteria and protists are also capable of autotrophic nutrition. These organisms utilize different mechanisms such as chemosynthesis or photosynthesis to synthesize their own organic compounds and derive energy from non-organic sources, such as inorganic chemicals or light, respectively.

Answer:

deoxygenated blood is pumped back to the heart with the superior vena cava and inferior vena cava. Blood is then in the right atrium then it is pushed to the right ventricle in the heart. it is the pumped through the pulmonary artery to the lungs(the pulmonary artery is the only artery that carries deoxygenated blood). In the lungs blood is pumped to the cappilleries in the bronchus where oxygen in the air is passed through to the blood with heamoglobin and thus now the blood is oxygenated. The blood is the pumped brought back to the heart with the pulmonary vein(the pulmonary vein is the only vein to carry oxygenated blood).It flows into the left atrium where it is then pushed down into the left ventricle and is then pumped up through the aorta to the whole body.
