One person pulls on a rope with a force of 400 N to the right. Another
person pulls on the opposite end with a force of 600 N to the left. What is
the net force?
Two forces are applied on the rope of the magnitude 400N to the right and 600N to the left, as a result of these forces the net force on the object will be 200N. Thus, the correct option is A.
What is Net force?Net force is the resultant force of the total force which is being applied on an object. It is the sum total of the effect of all the forces on an object. Forces which are applied in opposite directions cancel out each other.
If the net force applied on an object is not zero, then it can be said that the object is not in equilibrium, and thus Newton's Second Law can be used to determine the motion of the object.
Here, two forces of different magnitudes and in opposite directions are applied on the rope to pull the rope. The forces are 400N to the right and 600N to the left.
As a result of these forces, the net force applied on the rope can be calculated by:
Net force = Difference between the forces applied in opposite directions or the sum of the forces which are applied in same direction
Net force = 600N (force applied to the left) - 400N (force applied to the right)
Net force = 200 N and the direction will be left as the magnitude is more in left direction than right
Therefore, the correct option is A.

What is the biology
Answer:
science that studies living things
Explanation:
it includes plants and animals so basically anything that has life
Answer:
Biology is the study of living organisms, divided into many specialized fields that cover their morphology, physiology, anatomy, behaviour, origin, and distribution.
Explanation: Branches of biology are different topics related to biology; for example the 3 major branches of biology are:
Botany, also called plant science, plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field
Zoology is the branch of biology that studies the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems.
Microbiology is the study of microorganisms, those being unicellular, multicellular, or acellular. Microbiology encompasses numerous sub-disciplines including virology, parasitology, mycology and bacteriology.

What was the universe immediately before the Big Bang occurred?
a black hole
a singularity
a super spiral galaxy
a mass of antimatter
the answer is a black hole
The universe immediately before the Big Bang occurred as a black hole. Thus, the correct option is A.
What is the Big bang?The big bang may be defined as the cosmic explosion that significantly marked the initiation of the universe according to the big bang theory. The origin of the universe is explained by the Big Bang theory.
At initial, the whole universe appeared like a black hole where no life is present. It was all the dark around each and every corner. The universe was an infinite stretch of ultrahot, dense material and everything consisted of empty space.
Before the big bang, the universe was almost infinitely small, dark, and a size less than a trillionth of a second. It was a period of inflation which is followed by a more catastrophic event which was violent, and known as the period of expansion.
Therefore, the universe immediately before the Big Bang occurred as a black hole. Thus, the correct option is A.

While distinctly Anthropoids, some Platyrrhines maintain a few of traits that are typically represented only in Prosimians. For this question, identify the seemingly primitive traits and discuss how their presence in both Platyrrhines and Prosimians may reflect an example of convergent (parallel) evolution. (150-250 wds)
Convergent evolution is the concept of two or more species evolving similar traits despite being completely unrelated to one another, including the absence of a common ancestor.
The Platyrrhines, more commonly known as "New World Monkeys", share many characteristics with the Prosimians. Some of these include:
Teeth layoutDietEyesight Sleeping habitsand more.
The Platyrrhines and the Prosimians are both nocturnal animals. Despite all other members of their family being active during the day, the Playrrhines have evolved nocturnal habits similar to that of the Prosimians. Aside from that, they feed on insects more so than fruit, which is reflected by the layout of their teeth, and have eyesight well adapted to dark conditions. All of these are traits they share with the Prosimians.
Despite being in different ecosystems and regions, and sharing no recent common ancestors, both of these species have evolved strikingly similar traits. This can be used to corroborate the theory of convergent evolution, which explains how two species can evolve very similar traits despite being unrelated.

Answer: reading paper books and magazines, sleeping in beds under cotton sheets, having a sandwich for lunch , sitting at wooden desks , I picking wildflowers , eating a favorite breakfast cereal.
Explanation: These are all correct because each has to deal with plants. For example, reading the paper books, sleeping in the bed and sitting at the wooden desk all have to due with the products that come from plants. Paper, cotton, and wood are all grown from plants and turned into resources. Next picking flowers, eating foods are also direct examples of how plants help us. Picking flowers that come directly from plants. Then eating food that is grown from plants shows that it is directly plants providing for humans.

Marine biologists have determined that when a shark detects the presence of blood in the water, it will swim in the direction in which the concentration of the blood increases most rapidly. Based on tests conducted by the biologists, the concentration of blood (in parts per million) at a point P(x,y,z) on the surface of sea water is approximated by
Blood concentration is approximated by the distance from the source.
The concentration of blood at a point P(x,y,z) on the surface of sea water is approximated by the distance from the source where the blood moves. Point x is the place where the concentration of the blood is the highest because at this point the source of blood present.
At point y, the concentration of the blood is lower as compared to point x but higher than point z, while on the other hand, at point z the concentration of blood is the lowest due to its presence farther from the source so we can conclude that blood concentration is approximated by the distance from the source.
