Answer:
The correct answer will be- 30 percent
Explanation:
Pregnancy loss or miscarriage is the natural death of the fetus or the embryo due to which the growing embryo is unable to survive.
About 70-80% of the miscarriage occurs between the first trimester or first 12 weeks of the pregnancy.
About 30-40% of all fertilized eggs get miscarried before pregnancy is known that is before implantation, 30% following implantation but prior to the missed period and 10% due to clinical miscarriage.
Thus, 30 per cent is the correct answer.
The answer to this question would be D (DNA). It can be found in the nucleus of a cell and contains the entire genetic information of a whole.
Transpiration: process in which plants release water vapor into the air
Evaporation: process in which water changes to a vapor
Precipitation: water that falls from clouds toward the ground
Condensation: water vapor that cools down to form water droplets
Groundwater: flowing of rainwater downhill to form streams and rivers
So that it can sustain different life that requires different environments. Angler fish, for example, require a dark and cold environment to thrive while tuna require a light and warm environment.
The words for the descriptions are food chain, trophic level, energy pyramid, high diversity, low diversity, etc. respectively.
<h3>Ecology</h3>
- The feeding relationship that exists among organisms is termed the food chain.
- Each step in the transfer of energy and matter in a community is termed the trophic level.
- A community or group of living organisms that live in and interact with each other in a specific environment is termed an ecosystem.
- A diagram that compares the energy used by producers, primary consumers, and other trophic levels is known as the energy pyramid.
- An ecosystem with a high number of species is said to be of high diversity.
- An ecosystem with a few prominent species and a low number of other species is said to be of low diversity.
- Organisms that feed on and break down organic matter are said to be decomposers.
- Organisms that can make their own food in the ecosystem are termed, producers.
- Animals that feed on flesh are called carnivores.
- A system of interlocking and interdependent food chains is called a food web.
