Answer with Explanation:
The "passenger pigeon" used to be North America's most popular bird. Their population even reached 3 billion (or even more). They always traveled together. Their decline in number was noted in the 19th century. People became interested in hunting them for food because they were relatively cheap and tasty . They were also a great source of protein. It was easy to hunt them down although they could fly very fast because their flocks were huge in number. Some people killed them because they didn't want the birds ruining their crops. Their nesting grounds were also disturbed, which ultimately drove them away from the forests. People were overkilling them, and this sped up with the advancement of technology. The number of pigeons killed outnumbered the newborn pigeons, and after decades of hunting them down, their number dwindled with the last one passing away in 1914.

what is an outcome of lack of oxygen?
Answer:
Blood carries oxygen to the cells throughout your body to keep them healthy. Explanation:
Hypoxemia can cause mild problems such as headaches and shortness of breath. In severe cases, it can interfere with heart and brain function. Hypoxemia that causes low oxygen levels in your body's tissues is called hypoxia.
The outcome of lack of oxygen To maintain your body's cells healthy, blood provides oxygen to every cell.
What is cell ?The smallest unit that can sustain life on its own and makes up all living things, including the body's tissues. The cell membrane, the nucleus, and the cytoplasm are the three primary components of a cell. The substances that enter and leave the cell are governed by the cell membrane, which encloses the cell.
There are two different types of cells: prokaryotic cells, which lack a nucleus but still have a nucleoid area, and eukaryotic cells, which have a nucleus. Eukaryotes can either be single-celled or multicellular, in contrast to prokaryotes, which are single-celled organisms.
From bacteria to humans, cells give all living things their structure and functionality. They are regarded as the tiniest form of life by scientists.
Thus, To maintain your body's cells healthy, blood provides oxygen to every cell.

A helpful shortcut our brain makes in scene recognition is to assume that lighting comes from:
Answer: A. Above
Explanation:
Scientists believe that in order for humans to see things, the brain has to make certain assumptions which are done based on previous scenes that it has interpreted before because the eyes do not provide it with complete data. .
One of those assumptions is that light comes from above which is why the shape of a picture can change depending on the lighting in it.

What does a number in front of a molecular formula stand for???????
Explanation:
The small number behind each element symbol designates the number of atoms of each element in a chemical formula. If there is no number, it is assumed there is only one of those elements. A large number designates how many units there are of that compound.

Explain the difference between AKI and CKD
Answer:
Acute kidney injury (previously called acute kidney failure) is the sudden loss of kidney function, usually as a result of illness, drugs or injury. Acute kidney injury is commonly reversible. Chronic kidney disease (CKD) will progress to chronic kidney failure with time.
Explanation:
Answer:
AKI is reversible (for the most part) where CKD is not
Explanation:
AKI develops very suddenly. It is normally caused by an acute renal insult and encompasses a spectrum of renal impairment from minor changes in markers of renal function. Managing AKI includes; identifying and treating the underlying case and doing your best to minimize as many complications as possible.
CKD develops over time, normally taking a few months to years for it to show itself. It normally comes from having diabetes and hypertension. The disease itself is, more often than not, discovered when going through screening for other, unrelated, diseases. You can slow down the progress of renal failure but you can't treat it. CKD will eventually lead to permanent dialysis or the patient needing a kidney transplant.

DNA polymerase is an enzyme required in DNA replication. Its role is to synthesize DNA, adding individual nucleotides to each strand of newly synthesized DNA with the help of other enzymes such as primase and ligase. There are several families of DNA polymerase in both prokaryotes and eukaryotes, but through different species, portions of DNA polymerase are highly conserved. What do you think is the evolutionary significance of DNA polymerase? What do you think would happen if there was a genetic mutation on the genes encoding for DNA polymerase?
A sample answer would look like this: The DNA polymerase has evolutionary significance because it is required for DNA to be transmitted across generations. A genetic mutation in a gene encoding for DNA polymerase could lead to significant flaws in DNA replication, which could lead to major flaws in the DNA replicated for cell division. This could lead to large-scale errors and result in the death of the organism.
Answer:
Abstract. DNA polymerase I (pol I) processes RNA primers during lagging-strand synthesis and fills small gaps during DNA repair reactions. However, it is unclear how pol I and pol III work together during replication and repair or how extensive pol I processing of Okazaki fragments is in vivo

What do variations create?
Variations in species help them to adapt themselves to that particular environment and give them a chance of survival. For example, thermophilic bacteria are variants that are resistant to extreme temperature. They have a chance of survival in high temperate zones while others die.
