In Leonardo da Vinci’s time, nobody knew that the arteries were joined to the veins by tiny, invisible capillaries. This means that even though he studied the heart in detail, he thought that the arteries and veins were dead ends. Why did this make it difficult for him to understand how the heart worked?
Answer:
It was difficult for him to understand how the heart worked because he wasn't fully aware of the pumping mechanism of the heart and how the circulation of blood goes inside the body. Not seeing the capillaries meant that the heart pumped blood towards the vessels and into a dead end. He couldn't understand where the blood that was being pumped goes to.
Explanation:
Leonardo da Vinci is considered one of the earliest persons to study the heart. Although he made an exceptional observation of the different parts of the heart, he couldn't track the capillaries. He didn't know that these tiny structures connected the arteries and the veins. He believed that the heart was meant to transfer heat from the liver going to the muscles. He also believed that the lungs helped cool the blood.

After concluding his research, which statements would Virchow agree with? CHECK ALL THAT APPLY.
Living things come from nonliving things.
Cells can come from nonliving materials.
Frogs can come from mud.
Living things can only come from living things.
Cells come from pre-existing cells.
Answer:
Living things can only come from living things.
Cells come from pre-existing cells.
Explanation:
Rudolf Virchow a german physicist, biologist and many more, In 1855 Vproposed that cells come from pre-existing based on his observations in exact words 'Omnis cellula e cellula', which translates into all cells arise from pre-existing cells.
He also said the living things come from living things and do not arise from nonliving things or matter. His discoveries made possible the cell theory

What are the 2 types of fatty acids (and explain what each means, and an example)?
Answer:
saturated and unsaturated fatty acids
Explanation:
Saturated fats are a type of fat in which the fatty acid chains have all or predominantly single bonds.Rich sources of dietary saturated fatty acids include butter fat, meat fat, and tropical oils.
An unsaturated fat is a fat or fatty acid in which there is one or more double bond in the fatty acid chain. these include avocados, olive oil, fatty fish and nuts or seeds.

A medical student is studying how the volume of blood in the circulatory system affects blood pressure. He measures the blood volume and pressure of two classmates, a man and a woman. He finds that the man has a higher blood volume but a lower blood pressure than the woman. He concludes that a person with low blood volume would tend to have high blood pressure. What additional factors should the student consider that would most likely affect blood pressure? (1 point)

Photosynthesis and cellular respiration form direct ______ reactions.
Answer:
photosynthesis and cellular respiration form direct opposite reactions
Photosynthesis and cellular respiration form direct opposite reactions.Photosynthesis is the anabolic process and cellular respiration is the catabolic one.
What is the place for photosynthesis ?It takes place in the leaves where the chloroplasts have the cells that are undergoing the reactions where the food is synthesized.
Photosynthesis is the process by which plants prepare their food and it takes place in the presence of sunlight with the help of water and with the help of carbon dioxide it forms photosynthesis process where the reaction takes place.
Cellular respiration is the chain of reactions that are taking place in the cells where the reactions are taking place in the mitochondria and the chloroplasts and the reactions that are corresponding with each other.

Space between stars:
In astronomy, the interstellar medium (ISM) is the matter and radiation that exist in the space between the star systems in a galaxy. This matter includes gas in ionic, atomic, and molecular form, as well as dust and cosmic rays. It fills interstellar space and blends smoothly into the surrounding intergalactic space.The component of a galaxy which is colorful is disk:
The various colors in a galaxy (red bulge, blue disks) is due to the types of stars found in those galaxy regions, called its stellar population.Learn more:

A plasmid that encodes resistance to ampicillin and tetracycline is digested with the restriction enzyme PstI, which cuts the plasmid at a single site in the ampicillin-resistance gene. The DNA is then annealed with a PstI digest of human DNA, ligated, and used to transform E. coli cells. (a) What antibiotic would you put in an agar plate to ensure that the cells of a bacterial colony contain the plasmid
Answer:
tetracycline
Explanation:
When the DNA insert is ligated in Pstl site, the ampicillin gene is disrupted while tetracycline gene is still intact.
- If the bacterial colony is growth in a medium with only ampicillin, only the cells that contains the plasmid with the insert will grow.
- If the bacterial colony is growth in a medium with only tetracycline, the cells which have incorporated the plasmid will survive. We cannot distinguish between cells with plasmid + insert and plasmid alone.
- If the bacterial colony is growth in a plate with ampicillin + tetracyclin, only the cells with the plasmid without the insert will grow.
Therefore, to ensure that the cells of a bacterial colony contains the plasmid, they have to be seeded in a plate with tetracycline.

Explain how brassinosteroids are synthesised, perceived and promote plant growth and development. Please give named examples and critical analysis to support your answer
Answer:
Brassinosteroids are synthesized from phytosterols and they promote plant growth and development by modulating cellular processes (e.g, cell division, elongation, photomorphogenesis, responses to environmental stimuli, etc).
Explanation:
Brassinosteroids are phytohormones similar to steroid hormones. Phytosterols include sitosterol, campesterol, and stigmasterol, i.e., lipid (cholesterol) molecules that form the cell membranes. These polyhydroxylated steroidal phytohormones play a wide range of cellular roles during plant growth, development and immunity. Examples of brassinosteroid functions include plant development, xylem differentiation, responses to biotic/abiotic stresses, reproduction, etc. For example, campesterol, which is a precursor of brassinosteroid hormones, is an integral membrane component that functions during plant embryogenesis by regulating the permeability of cell membranes and by altering membrane-associated proteins, as well as signal transduction pathways.
