How important do you think technology is to agriculture? Why is it important that the agriculture industry stay current and evolve with technology? 5 sentences
Answer with Explanation:
Here's an example answer with 5 sentences.
Technology is very important to agriculture. It allows a higher crop yield and lowers the quantity of water, fertilizer and pesticides being used. The agriculture industry should stay current and evolve with technology in order to ensure a more efficient way of farming with lesser impact on the environment. This also ensures a safer growing condition for animals and plants, thereby affecting the quality of food that people eat. This makes agricultural businesses more profitable while maintaining an eco-friendly society.

Explanation:
A. no... the finches were living in different environments making them become less similar over time.
B. no... the Galapagos are long way from Africa... not possible
C. yes... This is true ... the size and shape of the beaks makes a big difference in the type of food the finches could eat. Seed types would change as climate change and finches would with the best beak size for the food available would survive.
D. no very unlikely. DNA Evidence show that the finches were from one common ancestor
The finches that Darwin studied differed in the shape of their beaks. According to darwin it become adapted to eating different foods.
Support your answer?The size and shape of the beaks make a big difference in the type of food the finches could eat.
Seed types would change with climate change and finches would with the best beak size for the food available to survive.
Thus, option "C" is correct whereas another option is very unlikely DNA Evidence shows that the finches were from one common ancestor.

The graph above gives the land surface air temperatures and the sea surface water temperatures from 1950 to 2016. Global
warming encompasses the changes in climate and temperature around the globe from the oceans to on land. However, when
studying the warming of Earthy's land and water temperatures, a difference between the two can be observed. From the graph, it
can be seen along most of the graph that the water temperature of the sea's surface remained lower than that of the land's surface
air temperature. What unique characteristic of water allows for this phenomenon to occur?
a. water’s heat of fusion
b. water’s conductivity of heat
c. water’s heat of vaporization
d. water’s specific heat capacity

A) it will shrink
B) nothing
C) it will explode
The cell shown in the image is placed in a solution of 0.5 M whereas the internal concentration of the cell is 0.1 M, hence the solution is hypertonic and the cell will shrink.
The correct option is A.
What is a hypertonic solution?A hypertonic solution is a solution with a higher concentration of solutes (e.g. salt, sugar, or other molecules) compared to another solution.
When a cell is placed in a hypertonic solution, water molecules will move out of the cell and into the surrounding solution, which can cause the cell to shrink or even collapse. This is because the concentration of solutes inside the cell is lower than that of the hypertonic solution, so water diffuses out of the cell in an attempt to balance the concentration on both sides of the cell membrane.

1. How many pounds of biological material is below that soil surface?
Answer:
The amount of organic matter in mineral (sand, loam or clay) soils ranges from very low being 1% by weight, to average being 2 to 4%, and high being greater than 5%. There are also “muck” or organic or peat based soils that are 30 to 40% organic matter. The general consensus is the more soil organic matter the better. approximately 45%
Soil Composition
The basic components of soil are minerals, organic matter, water and air. The typical soil consists of approximately 45% mineral, 5% organic matter, 20-30% water, and 20-30% air. These percentages are only generalizations at best.

Which scientist would agree with this statement: Giraffes all had short necks originally. Individual giraffes stretched their necks for food. The "acquired" long necks from stretching were then passed on to the offspring. The giraffe population became long-necked please help I need to figure out which scientist it is
Answer:
Jean-Baptiste de Lamarck
Explanation:
His two principles were "use and disuse" and "inheritance of acquired characteristics." The latter is what the statement is referring to.
Answer:
Lamarck
In the case of a giraffe, Lamarck believed that giraffes once had short necks that got progressively longer as members of each subsequent generation stretched their necks as long as they could. In doing so, Lamarck believed that each generation would grow slightly longer necks and pass that trait onto their offspring.Jan. 16, 2018

What is Sunny weather?
Sunny weather is described as the type of weather where the sky is blue, the grass is bright, and there is a lot of sunlight that is usually warm when the sun comes out, so people in cold climates find it quite looks nice. People may not be so fond of this weather.
When it comes to absorbing heat on sunny days, the color of the fabric is more important than the length or material it is made of, when compared to a black shirt with short sleeves, a long sleeve white shirt can make you feel colder because of all the colors.
So when we wrap a black paper on something like jar it will get warmer as compared to other colour papers.
Thus, a jar placed in a sunny window will get warmest if it is wrapped loosely in Black paper. So, the correct option is (G)
