Answer:

The oxygen enters the bloodstream from the alveoli, tiny sacs in the lungs where gas exchange takes place.The transfer of oxygen into the blood is through simple diffusion. The oxygen-rich blood returns to the heart

What specific information leads to the belief that gene switching is the future of biotechnology?
ArbitrLikvidat [17]

The particular information that supports the idea that gene swapping will shape biotechnology's future is that it will shield plants from severe environmental factors like pests and drought. The productivity of food production can also be increased by gene flipping.

<h3>How may a rise in soil conservation measures be caused by the application of biotechnology?</h3>

With the use of biotechnology, farmers may use ecologically friendly farming techniques to raise more food on smaller plots of land. Through biotechnology, crops are naturally resistant to some insect pests and illnesses, seeds produce more per acre, and agricultural practises enhance soil conservation.

Pests and weather can have a negative impact on crop output, but genetic engineering can assist. Scientific developments have enhanced communication and transportation. Medical technological advancements have had little effect.

Read the list of words.
damaskus [11]

Answer:

it is because glands are not from outer body coordination

Explanation:

brain,motor neuron,movement,etc are components that involve in coordination like when somebody accidentally touches a hot surface or hear the sound of the door bell

while the glands involve in inner body coordination such as maintaining blood pressure,glucose level in blood etc

glands synthesis hormones that help keep the body in optimal condition

in all three complex carbohydrates the subunits of glucose are bonded together differently. Because they have different structur
ss7ja [257]

Explanation:

options:

  1. contain different chemical elements
  2. form different proteins
  3. carry different nucleotides
  4. perform different functions

Because they have different structures, they most likely-<u>perform different functions.</u>

<em>The corresponding image is attached below...</em>

Carbohydrates function to supply energy and support molecules they consist of mainly sugars or starches in long chains and rings to form monosaccharide monomers. They include monosaccharides, disaccharides and polysaccharides which describes the type of bonding and the degree of complexity of the polymers.  Their structure is closely related to their function.

Basic makeup: C, H, O -with many polar OH groups

Further Explanation:

Many long chain polysaccharides are made up of glucose joined by regular α, 1-4 glycosidic bonds used as energy storage (produced through phtosynthesis) and used for ATP synthesis via respiration, ethyl alcohol fermentation and lactic acid fermentation. Branched chains of α, 1-4 glycosidic bonds linked by α(1→6) glycosidic bonds make up glycogen, a storage molecule in animals. Plants are mostly comprised of structural units cellulose and lignin. However, cellulose is their main structural polysaccharide, found within cell walls.

It is made up of special β, 1-4 glycosidic bonds, which give structural polysaccharides their rigid, strong structure; cellulose is not water-soluble and is highly stable. However, if these alternating bonds aren't present, the plants would lose their main structural support, which allows larger plants, and trees to grow upwards towards sunlight despite their mass.  When arranged in α 1-4 glycosidic bonds these molecules are water-soluble; water would be able to flow readily out of the plant tissue. Thus the plant cells and tissue, would not retain their shapes and may be limited in their potential height without structural support.
