Using the terms DNA, trait, code, pattern, gene, describe why each organism is unique
Rom4ik [11]
Each organism is unique because of genetic variation. Each set of genes we inherit from our parents codes for a specific trait. And our DNA is a blueprint for these traits. Not everybody contains the same genes and that is why we are all so beautifully unique.

ancestors of giraffes with shorter necks could not reach branches high up in trees for food. this led to selection for longer-ne
hichkok12 [17]

With shorter necks, giraffe ancestors could not reach food-containing branches on tall trees. This resulted in the directional selection of giraffes with longer necks.

 

<h3>Why is choosing a direction necessary? </h3>

It nearly appears obvious that the giraffe's long neck developed as a result of a lack of food in the lower branches of trees. The giraffe has a significant advantage because it is taller than any other mammal and can feed where few others can. 

When compared to modern giraffes, the giraffe's ancient predecessors had a shorter neck. The plants that were lying at a higher level were inaccessible to them. Giraffe phenotypes have changed in various ways, and now have long necks to reach vegetation that is higher up. The extreme form is chosen above other features in directional selection. It was decided to choose the long-necked giraffe over the short-necked.

Crop monitoring makes use of space-based data to keep tabs on crop development and forecast crop yields for certain fields that have been planted.

<h3>What is monitoring systems?</h3>

A system for monitoring agriculture consists of a network with wireless sensors. These sensors gather information from several nodes positioned on the playing surface. Then, specialists or nearby farmers analyze this data. The data can be used to make a number of inferences about weather patterns, soil fertility, crop quality, etc. A system is developed for agricultural field monitoring in IoT-based modern agriculture with the aid of sensor like light, humid, temperatures, soil moisture, etc. Farmers may monitor the condition of thier fields from any location. IoT-based smart farming is considerably more efficient than conventional farming.

<h3>How do farmers monitor their crops?</h3>

Nowadays, satellite techniques are widely employed in agriculture, and many farmers use them frequently to observe their fields and assess the condition of their crops. Crop monitoring is crucial for managing various pests, weeds, and diseases that affect crops. This gives information about the crop's current situation, and you can then look ahead in time to forecast what will probably be the crop's next problem.

Scientist are studying an 500g. Sample of a radioactive element. Which has an annual decay rate of 11%. How many grams of the sa
gtnhenbr [62]

Nothing

Explanation:

Mass of the sample = 500g

Decay rate per anum = 11%

Unknown:

Mass of sample remaining after 10yrs = ?

Solution:

  This is a simple percentages problem;

The radioactive sample loses \frac{11}{100 } x 500g of sample per year;

  this is a loss of 55g per year;

In 10years time, the sample would have lost 10 x 55g = 550g of element.

Since our sample is not up to 550g, then no amount of sample will remain after 10yrs.
