Red blood cells contain a protein called hemoglobin. An illustration of red blood cells showing the hemoglobin protein. This protein serves as a transporter of oxygen from the lungs to tissues.

<h3>What are proteins?</h3>

The term "protein" refers to a macro- and large-scale biomolecule that has one or more lengthy chains of amino acid residues.  An amino acid chain makes up the basic building block of proteins.

When oxygen binds to the heme portion of the hemoglobin molecule in red blood cells during physiological respiration, oxyhemoglobin is created. This procedure takes place in the pulmonary capillaries close to the lung's alveoli.

Thus, red blood cells contain a protein called hemoglobin. An illustration of red blood cells showing the hemoglobin protein. This protein serves as a transporter of oxygen from the lungs to tissues.

Explain the difference between sexual reproduction and asexual reproduction. Explain either an advantage or disadvantage for
ira [324]

In asexual reproduction, reproductive organs aren't used but they're used.

advantage of sexual- A lot of genetic variation. since they have DNA of two parents. they can survive more and adapt more.

disadvantage of asexual- diversity is limited. Since the organism only gets the DNA of one parent, they wouldn't be able to really survive if something happened.They would easily be extinct.

Sorry I can't really cone up with better words but I hope you get the idea. it all comes down to natural selection really if you've learned about it. Hope it helped!!!

True or false: surveillance can be performed through either stationary or mobile means.
Ivanshal [37]
<span>This is true. Surveillance can be performed efficiently through both stationary and mobile means. As far as human surveillance goes, people can track other people by tailing them or by using a stationary means such as a stake out. As far as technology goes, there are plenty of mobile devices that can be used for surveillance such as tracking devices. Security cameras can be used for stationary purposes.</span>
