Between 1957 and 1961, thousands of expectant women in 30 different nations ingested a common antinausea drug of the time known

Elza [17]

Answer:

A study of those newborn babies

Explanation:

Studying the infants from these pregnant women lead the researchers to find out that this drug interfered with the process of limb formation if the pregnant woman had taken this drug anytime during the 26 days critical for limb formation and development. In this way, it makes for an instance where nurture had disrupted nature.

Suppose a rancher wants to raise cattle. Design a plan to help the rancher determine how much land she'll need based on the ener

BARSIC [14]

Answer:

The energy flow in the ecosystem decreases as it flows from one trophic level to the next trophic level. Only 10% of the energy will transfer to the next trophic level and the remaining energy is lost in the other metabolic process.

The energy flow in the case of the grassland can be shown by the trophic relationship of the organisms. The sun is the primary source of the energy that are absorbed by the plants through the photosynthesis process. The cattle acts as herbivores will consume the plants energy by directly feeding on them. The ranch should be protected from the other animals that feeds on cattle and they are known as carnivorves.

This type of membrane transport moves substances against the concentration gradient from an area of low concentration to an area

sashaice [31]

Answer:- Active transport

Explanation:-

There are two types of membrane transports

1. Passive transport - this type of transport occurs without the input of any energy and the molecules move along the concentration gradients that is from high concetration to low concentration.

2. Active transport- this type of transport takes place to move the molecules against the concentration gradient that is from low concentration to high concentration.

The active transport is of two types:

1. Primary active transport- in this type of transport ATP is used as an energy source to move the substances against the concentration gradient.

2.Secondary active transport - in this type of transport the gradient formed by the active transport is utilized and it involves the movement of 2 substances at a time aross the membrane. That is the movement of one molecule is coupled to another.

The membrane proteins that are associated with active transport are called as carrier proteins. These proteins have a binding site for the molecules that they transport. Once they bind to the specific molecules, a conformation change is induced and this leads to the transport of the molecule across the membrane.

So, the active transport is basically responsible for utilizing the energy from ATP and carrier proteins to move the substances across the membrane against their concentration gradient i.e. from low concentration to high concentration.
