<h2>Human Population</h2>

Explanation:

  • This investigation permits us to defer or  prevent extinction of our species and demonstrate monetary qualities and shortcomings by locale and by nation and furthermore by ethnicity.
  • The key part is these investigations demonstrate populace wellbeing and life span of the species , with purpose of i<em>mproving and dragging out said essential segment .  </em>
  • Death rate is commonly communicated in units of passings per 1,000 people for every year. in this manner, a Death pace of 9.5 (out of 1,000) in a populace of 1,000 would mean 9.5 passings every year in that whole populace, or 0.95% out of the aggregate.  
  • The natality rate for the populace. At the point when you put these components together you can portray how the populace is either developing or declining.
  • Fundamentally,  development will be the<em> births - passings + migration - resettlement.</em>

Over a long period, how might living things adapt to increased carbon dioxide levels and global warming?
SCORPION-xisa [38]
Yes. We could be done for if it is anthropogenic and if it is not being caused by CO2 as we are lead to believe. CO2 may not be the only anthropogenic cause (if it is a cause).

If climate change is due to weather engineering by chem trailing in conjunction with ionospheric heating, then it could cause serious illness to our species.

The use of the electro-magnetic spectum and radio waves by ionospheric heaters, could cause genetic damage as well as infertility. Whether other sources of RF/EMF also play into weather manipulation and control is unclear. Whether the use of ionospheric heaters contributes to climate change is unclear, but it intuitively seems likely. Creating a sustaining a plasma in the ionosphere may heat up more than the ionosphere and it may have an impact on the weather.

We do not know what chemicals are being used to obscure the sun, create clouds, perhaps create rain and wind, (nor why) and therefore we do not know if those could also contribute to infertility or genetic damage when they finally wash out of the sky. We do not know if the chemicals can be absorbed through the skin, or what happens to us when we breathe them, or consume them in our drinking water or in the food we eat. Higher levels of certain metals have been measured in the soil after chem trails. It is difficult to know which tests to use to test for all the chemicals which can be used.

1. How might the daily experiences of people contribute to their belief the earth and species do not change?
MariettaO [177]
People's daily experiences can contribute to their belief that earth/ species do not change because we are changing with it as it is happening. Also the changes happen gradually so you can't constantly see to believe it.

A person's blood type is determined by the:_______
matrenka [14]

Answer:

) Presence of specific glycoproteins on the cell membrane

Explanation:

When specif glycoproteins(antigens)  or antibody are present on a cell membrane of Red blood cell,they can  be used to identify the blood type.Antigens are substances capable of triggering an immune response in a cells.

In addition,they function in transport of molecules across the RBC. They help in the maintenance of the RBC,and aiding the arrest of cells capable of causing diseases to the body.

Therefore,they are good determinants of blood types,based on this two types of antigens present in a  blood type.

These two antigens  used for classification of blood types are the 1-the ABO antigens 2,the Rhesus antigens.

Essentially,when a WBC produces an antibody ,which is a molecule that defends the body,If this is not compatible,the antibody will recognize it as a foreign body and attack it.Thus such blood types are not compatible. Thus the antibody-antigen reaction are good for knowing and classify blood types.

Antigen can also be glycoprotein,carbohydrate or glycolipids.

Generally blood types are inherited from both parents.Therefore the antigen present on the RBC are combination of the alleles from each parent.
