Their new study shows that humans are strange predators. Unlike other animals, we target adult prey in large numbers. That is a practice that can push populations of those prey into decline, the researchers warn. People mainly target — at least among wild mammals and fishes — prey that are old enough to reproduce.
Humans are considered to be apex predators in their ecosystems due to their ability to manipulate and dominate other species through hunting, agriculture and urbanization.
Why are human predators?Humans are considered to be apex predators in their ecosystem due to their ability to manipulate and change their environment to suit their needs. Humans have the ability to hunt and consume a wide variety of other organisms, including other predators. Humans also have a significant impact on the environment through activities such as deforestation, pollution, and hunting.
However, humans are also capable of acting as stewards of the environment and preserving biodiversity through conservation efforts. The relationship between humans and their ecosystem is complex and multifaceted.

What was known before Franklin and Wilkins conducted their studies of DNA? Select three options.
DNA is found in the nucleus of a cell.
The human genetic code is made of 50,000 genes.
Organisms store and transmit genetic information.
DNA has a double-helix structure.
Cells contain protein molecules.
The correct answer will be-
1. DNA is found in the nucleus of a cell
2. Organisms store and transmit genetic information
3. Cells contain protein molecules.
Explanation:
The study of DNA started much before the discoveries of Rosalind Franklin and Maurice Wilkins.
Nucleus of cell was discovered by Robert Brown in 1831 but the material present inside the nucleus called "nuclein" (DNA) came from the studies of Johann Friedrich Miescher in 1869.
Proteins as a constituent of cell were discovered by the experimental analysis of Gerhardus Johannes Mulder in 1837.
DNA as a genetic material came from the experimental studies of Frederick Griffith in 1928, Oswald Avery, Maclyn McCarty, and Colin MacLeod in 1944, and Hershey and Chase in 1952.
Franklin and Maurice Wilkins are known for their work on the the structure of DNA as they were able to produce high-resolution X-ray photographs of DNA fibres called Photo 51 in 1952 using X-ray diffraction technique. By 1953 Franklin concluded concluded that DNA shows helical structure with phosphates on outer side.
Thus, 1. DNA is found in the nucleus of a cell
2. Organisms store and transmit genetic information
3. Cells contain protein molecules.

Passive transport into cells is driven by a concentration gradient; a greater concentration of molecules on one side of the membrane.
Which direction would oxygen move across a cell membrane if there was a greater concentration of oxygen molecules on the inside of the
membrane?
A. It would continue to concentrate inside the cell.
B. The random diffusion of oxygen would balance and have no net effect.
C. Towards the outside of the cell.
D. None of the above.
Answer:
A. It will continue to concentrate inside the cell.
Explanation:
Due to the higher concentration of oxygen molecules on the inside, oxygen molecules of the outside move to the inside and the more the oxygen molecules move inside the higher the concentration of the oxygen molecules on the inside.
Answer:
A
Explanation:
Towards the outside of the cell.

which statement below correctly describes the process of glycolysis?
A. Glucose is broken down into two pyruvate molecules
B. Oxygen and glucose are broken down
C. Two pyruvate molecules are brown down into glucose
D. Glucose is broken down into ATP
Answer:
A)glucose is broken down into two pyruvate molecules
The statement below correctly describes the process of glycolysis, glucose is broken down into two pyruvate molecules. The correct option is A.
What is glycolysis?Glycolysis is the process in which glucose is broken down to produce two molecules of pyruvic acid, which also releases energy. This process can be carried out without the help of oxygen, thus an anaerobic reaction. This process is carried out in the cytoplasm.
For the cell to use as energy, glycolysis results in a net gain of two pyruvate molecules, two ATP molecules, and two NADH molecules. Following the conversion of glucose to pyruvate, the Krebs Cycle is connected to the glycolysis pathway, where additional ATP will be produced to meet the energy requirements of the cell.
Therefore, the correct option is A.

The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed.
What is RNA polymerase?RNA polymerase is an enzyme that aids in the transcription of DNA into RNA during transcript in the nucleus. The enzymes prevent many genetic mutations from being expressed.
Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis during replication as the DNA polymerases cannot begin the synthesis of the new strand, they only extend it after primase begins it and primase produces RNA molecules, the enzyme can be said to be a type of RNA polymerase.

Tectonic plates are pieces of the rocky outer layer of the Earth known as the crust. These plates are constantly moving, and volcanoes and earthquakes are found at plate boundaries.
At the borders of major tectonic plates, earthquake and volcanic activity is evident. The correct option is b.
What are tectonic plates?A tectonic plate (also known as a lithospheric plate) is a huge slab of solid rock that is made up of both continental and oceanic lithosphere. Plate size can range from a few hundred kilometers to hundreds of kilometers; the Pacific and Antarctic Plates are among the largest tectonic Plates.
The majority of volcanoes and earthquakes form at the tectonic plate boundaries of the Earth. These plates are massive slabs of the Earth's crust and upper mantle that fit together like puzzle pieces.
Tectonic plates are fragments of the crust, the Earth's rocky outer layer. Volcanoes and earthquakes can be found along plate boundaries because these plates are continually shifting.
Therefore, the correct option is b. Earthquake and volcanic activity are evident.
