Two species of shorebirds are both adapted to live in coastal marshes. One species outcompetes the other for the small fish that
NNADVOKAT [17]

Answer:

The population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

Explanation:

According to the Competitive exclusion principle, which is also known as Gause's Law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

As we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

Coming towards the question, what wi ll happen when One species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. Eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

Hope it help!

Determination of Caloric Content of Three Foods1. Compare the calorimeter that you built to a bomb calorimeter. How are they sim
yulyashka [42]

Answer:

The answers to both parts (1 and 2) are given below.

Explanation:

1. The calorimeter is similar to the bomb calorimeter in a way that both measure the changes in heat that occur as result of the chemical reaction taking place inside them. They are different in the sense that a bomb calorimeter provides an isolated system with constant volume and pressure, whereas a regular calorimeter allows pressure to equalize with the environment.

2. Carbohydrates are the molecules that break down and provides energy for cellular functions. Whereas, proteins are not meant for the production of energy but for the production of amino acids to function as structural units for protein synthesis. Simply, the breakdown of protein is for the synthesis of more proteins by providing several units of amino acids rather than the production of energy.

Give an example of how an organism can use surface tension?
aliya0001 [1]
Insects, such as water striders, and spiders, such as fisher spiders, can glide or scamper across the surface of water. These critters are small enough that their weight can be supported almost entirely by surface tension, the relatively weak forces that hold water molecules together.




Surface tension of water helps creatures(mostly of insecta class such as water striders) to walk on water. ... it also helps water to move up the xylem tissue of higher plants without breaking up

A biochemist isolates and purifies various molecules needed for DNA replication. When she adds these molecules to DNA, replicati
olga55 [171]

Answer:

DNA ligase

Explanation:

<em>The biochemist must have left out DNA ligase enzyme.</em>

<u>The DNA ligase enzyme is able to catalyze the formation of phosphodiester bonds and as such, capable of joining strands of DNA together to form a single strand.</u>

The numerous DNA segments of a few nucleotides long observed by the biochemist must have been the replicated product of the lagging DNA strand. The lagging strand is replicated discontinuously in short strands because the DNA polymerase enzyme can only elongate primers in 5' to 3' direction. The short segments are known as Okazaki segments and are usually joined together to form a whole strand by the DNA ligase enzyme.

Hence, the missing component is the DNA ligase.

Describe the role. of the liver in regulating the concentration of glucose in the body​
leva [86]

Answer:

The liver stores glucose to power the cells during periods of low blood sugar. Skipping meals and poor nutrition can lower blood sugar. By storing glucose, the liver makes sure that blood glucose levels remain steady between meals and during sleep. When blood glucose falls, cells in the pancreas secrete glucagon.
