Are humans affected by natural selection?

Answers

Answer 1
Answer: Yes! A recent example could be babies that do not survive child birth for a certain reason, are obviously unable to pass on whatever caused them to die in the first place.
Also, once humans started to domesticate cows and drink their milk (I'm not sure why humans drink a cow's milk) their bodies evolved to continue making the enzyme to digest milk even after they were weaned off their mothers milk. Many people of Asian descend do not have this enzyme, since their culture did/does not raise as much dairy product.

Which energy transfer is least likely to be found in nature ? A- consumer to consumer
B- producer to consumer
C-host to parasite
D- predator to prey

Answers

The energy transfer that is least likely to be found in nature is predator - prey. Details about energy transfer can be found below.

How is energy transferred in nature?

Energy is transferred in nature when organisms feed on one another.

For example;

  • Producers, which are the initiator of the energy transfer are fed upon by consumers

  • Consumers like herbivores are also fed on by other consumers like carnivores

  • Parasitic organisms feed and derive nourishment from their host

However, the transfer of energy does not occur in the direction of a predator to prey but occurs the other way around.

How will you describe the sequence of oxygen carbon dioxide and blood flow?

Answers

As we inhale air, oxygen enters the respiratory system and the circulatory system to transport it to the other parts of the body and to all cells. As the oxygen is already transported, the blood becomes deoxygenated and carries a CO2 which returns to the lungs and then we exhale the carbon dioxide.

3. Under which type of change would more organisms be able to survive? Why?

Answers

Most animals are well adapted to their biotic and abiotic conditions due to behavioural, physiological or structural adaptations that increase their chances of survival and reproduction. I looked it up for you

All proteins are synthesized by ribosomes in the cell. some ribosomes float freely in the cytosol, while others are bound to the surface of the endoplasmic reticulum. most proteins made by free ribosomes function in the cytosol. proteins made by bound ribosomes either function within the endomembrane system or pass through it and are secreted from the cell. which of the following proteins are synthesized by bound ribosomes?

Answers

ost proteins that function in the cytosol (such as actin) or in the nucleus (such as DNA polymerase) are synthesized by free ribosomes. Proteins that function within the endomembrane system (such as lysosomal enzymes) or those that are destined for secretion from the cell (such as insulin) are synthesized by bound ribosomes.
As a protein destined for the endomembrane system is being synthesized by a ribosome, the first amino acids in the growing polypeptide chain act as a signal sequence. That signal sequence ensures that the ribosome binds to the outer membrane of the ER and that the protein enters the ER lumen.

If all of your blood vessels were connected end to end, how many miles would they run?

Answers

If all of your blood vessels were connected end to end they would run for about 60,000 miles The main purpose of the blood vessels is to carryout the blood throughout every single tissues in our body, and often time the vessels will do a cricular motion of transportation when they transfer the blood in an organ, which will technically extended its transportation distance

How can technology be used to save nature

Answers

Answer:

Technology is also being harnessed to help prevent food waste, working to keep food out of landfills by keeping better track of it at all levels, from the farm to the table. With up to a third of the world's food resources thrown out, data collection technology has the potential to greatly reduce that figure.

His first prototype was simply an airtight, watertight pouch containing 40 g of ammonium chloride (NH4Cl). He added 100 mL of water to the ammonium chloride, sealed the pouch tightly, and then wrapped the pouch around a small bottle of water. He tested his prototype by measuring the temperature of the bottle of water over time. Next, Rodrigo performed the same test with different amounts and different concentrations of the ammonium chloride solution. For each set of measurements, he found the lowest temperature reached by the bottle of water and calculated the total temperature change. The table below summarizes his results. Maximum Cooling Achieved ___________________________________________ trial 1 2 3 4 5 6 7 ___________________________________________ grams of NH4Cl 30 40 50 50 60 70 80 ___________________________________________ amount (mL) of water added 100 100 100 150 150 200 200 ___________________________________________ greatest temperature change (–°C) 3.6 4.3 4.3 4.8 5.2 5.6 5.8 ___________________________________________ Finally, Rodrigo held the amount and concentration of the solution constant while trying different amounts of insulation.
