Had you been Louis Pasteur what would have been your reflections and conclusions based on this experiment?

1 answer:

6 0

If I had been Louis Pasteur, my first reflection would be that the experiment was able to produce milk with longer shelf-life. From there, I would make inferences as to how it happened. I already have knowledge about microorganisms and how they react or degrade with heat and pressure. So, I would conclude that by subjecting the milk to that specific temperature and pressure, the microorganisms that cause spoilage are destroyed.
Later on, I would also realize that it's not only the spoilage-causing bacteria that are destroyed but also all the other microorganisms present in the milk examples of which are probiotics.

Fofino [41]

Answer:

The correct option is : c. Herbivore

Explanation:

Herbivores are animals that are physically and anatomically adapted to eat autotrophs such as plants, photosynthesizing bacteria and algae as the main component of its diet. Such animals are commonly called primary consumers, as they generally feed on plants.

The digestive system of a herbivores generally consists of multiple stomach chambers and along with a long digestive tract to help in the break down of plant material. Therefore, the herbivores with long and multi-chambered digestive systems are called ruminants.

Examples: cattle, camels, sheep, deer and giraffes .

Which organ produces estrogen and progesterone?

NemiM [27]

The ovaries produce estrogen and progesterone in women. Both play an important role in the menstrual cycle: estrogen stops FSH production and stimulates LH release by the pituitary gland. Progesterone maintains the uterus’ lining. Men also produce estrogen, though at lower levels, and this is done through changing testosterone into estrogen with an enzyme.

Anastaziya [24]

Complete question: A phylogenetic tree shows that birds and crocodiles share many features. A hypothesis based on this tree predicts that these features are present in a common ancestor. Which of these predicted traits is supported by fossil evidence?

A) four-chambered heart

B) singing for territory

C) eggs and nests

D) singing to attract mates

Answer: (c) eggs and nests

Explanation:

A hypothesis based on phylogenetic tree shows that birds and crocodiles have ancestral connection. Fossil evidence shows that their common ancestor exhibit oviparity as a means of reproduction (i.e. laying of eggs and embryo develops within the egg), and also housed their eggs in the nest for protection against predators and other important reasons.
