Which of the following is a true statement? a. Mammals were the prominent species just before the extinction of dinosaurs. b. Ma
Angelina_Jolie [31]

Answer:

The correct answer is B.

Explanation:

Option A is wrong. Mammals were not the prominent species before the extinction of dinosaurs because the mammal species that lived during the dinosaurs' era were so small that they only weighed several grams and occupied small areas as their habitats.

Option C is wrong. As dinosaurs became extinct, reptiles and "birds" remained as their descendant which evolved to some of the species that we know today.

Option D is wrong. Pangea started to break up to form the geographic isolation for the diversion of many species around 175 million years ago.

So the correct answer is B. Massive extinction disrupts and changes the food chain in such a big way that it triggers a domino effect that leads to species adapting to their new environment and diversifying thus forming new species in the process.

I hope this answer helps.

IRISSAK [1]

Answer:

A) Calcitonin injection

Explanation:

Parafollicular cells or C-cells of the thyroid gland produce a hormone which is involved in the regulation of calcium levels in the blood. This hormone is Calcitonin. It works in an antagonistic manner with the Parathyroid hormone (PTH). Calcitonin decreases the calcium level in the blood by increasing absorption of calcium ions in bones. In osteoporosis, when the patient is given the injection of hormone calcitonin, it produces and increase in bone mass because it negatively affects the rate of absorption of bone by the osteoclasts.

Four stage in which abortion cannot be done.
VikaD [51]

Answer:

Fourth trimester.

Explanation:

Fourth trimester is the fourth stage in which abortion can not be done because the baby is big enough in size and comes out from the womb. The abortion in this stage can put the life of the mother in danger so that's why abortion is not allowed. Newborn babies are learning to adjust itself to life outside the womb where it was warm so we can say that  fourth trimester is the stage in which abortion is risky and dangerous.
