One person is pushing a cart with a force of 300 units to the right. Another person is
pushing on the same cart with a force of 450 units to the left. What is the unbalanced net
force acting on the cart?
150 units to the left
O 150 units to the right
750 units to the right
O Option 4
Answer:
The answer is 150 units to the left.
Explanation:
You start with the bigger number and subtract it because they ´re going opposite directions. It goes to the left because your net force will go in that same direction with the bigger number.
450 - 300 = 150 units to the left

This table list traits of four types of vertebrates. Each trait first appeared in a common ancestor of the animals that evolved later. These traits are used to build a branching diagram.
Based on the information in the table, which animal belongs in the spot labeled A on the branching diagram?
A.Tuna
B.Frog
C.Robin
D.Shark
The outgroup is the most distant group that appears in a branching diagram. It shares a common ancestor with the rest of the groups but expresses none of the traits they express. In this example, sharks belong to the outgroup A. Option D.
What is an outgroup?
In a phylogenetic trees or cladograms, the most distant group is called outgroup. It shares no traits or characters with the lineages of interest that compose the ingroup.
You can compare the outgroup with the ingroup to determine the evolutive relationship and which characters are primitive or derived.
Even though the outgroup shares a common ancestor with the ingroup, this is placed far away in evolution, making the outgroup to be the taxonomic group less related to the other lineages.
The lineages in the ingroup share another common ancestor that is more recent in history.
In the exposed example, A is the outgroup. It shares a common ancestor with the other groups, but express none of the characters mentioned in the tree. This is because it evolved before these charecters emerged.
Option D is correct. Sharks belong to the A group. As you can see in the table, it has none of the mentioned traits. It does not have a bony skeleton, lungs, amniotic eggs, or feathers.

Where do cold fronts form and what type of weather is formed?
Answer:
Cold fronts form when a cooler air mass moves into an area of warmer air in the wake of a developing extratropical cyclone. The warmer air interacts with the cooler air mass along the boundary, and usually produces precipitation
Which example describes animals living in a social hierarchy? Check all that apply.
an anteater’s light sleeping pattern to protect itself
a worker bee defends the hive while the queen bee lays eggs
a mole that makes and elaborate tunnel system
a prairie dog barks to alert family members when it spots a predator
a red panda searching at night for food
Answer:
A worker bee defends the hive while the queen bee lays eggs
A prairie dog barks to alert family members when it spots a predator
Explanation:
Just like people, some animals live in communities, where each of them plays a certain role. For those animals, we can say that they live in a social hierarchy.
Examples that describe something like this are the second and fourth ones.
In a hive, there are different types of bees: workers, drones, and a queen. Each of them plays their role, which makes their hive function properly.
Prairie dogs are another example of species that live in large communities. Since they are small and have numerous predators, they rely on each other for protection. They do this by barking whenever they spot a predator, this way alerting other members of their community.
The rest of the statements simply tell about how some species live without mentioning their social life. This is why they are incorrect.

Which stage(s) of the cell cycle has the most DNA and why?
Answer:
For cells in the body that replicate, they undergo mitosis to produce two identical daughter cells from one stem cell. These cells are going through a cycle, called the cell cycle, with several stages leading to the formation of daughter cells. The longest stage, and the one in which most cells are found, is called interface

If you were to graph air pressure with altitude, what would the graph look like?
Answer:
The correct answer would be - radiation curve graph.
Explanation:
The graph between air pressure with altitude would be a curve graph. The curve graph looks like one end at the x-axis and another end at the y-axis which indicates that if one variable increases then another variable would decrease accordingly.
It is due to the fact that air pressure decreases with the increase in elevation or altitude. So if the x-axis represents the change in air pressure and y-xis represents elevation it will look like a curve.
A graph that shows air pressure v. altitude would be a downward sloping curve.
If the air pressure was graphed on the y-axis and the altitude was on the x-axis, the graph would be downward sloping.
Why would the graph be curved and downward sloping?The greater the altitude, the lower the air pressure because there is less air as one goes higher into the atmosphere. The curve is because the rate of change is not constant.In conclusion, such a graph would be downwardly sloping and curved to show that air pressure and altitude have an inverse relationship.

In radishes, red (R) and white (W) are pure-breeding colors, while hybrids are purple (RW). If a red radish is crossed with a white radish, what will be the phenotype of the offspring? Show the Punnett Square and percentage of each phenotype.
Help please
Explanation:
We have a case of incomplete dominance (purple is an intermediate heterozygous phenotype in radishes)
Parental genotype => RR x WW
F1 genotypic ratio => RR:RW:WW = 1:2:1
F1 phenotypic ratio
=> Red : Purple : White = 1:2:1.
A single cell of testis divides to produce:
a. 4 sperms.
b. 6 sperms.
c. 2 sperms.
d. a single sperm.
Answer:
Each primary spermatocytes goes through the first meiotic division, meiosis I, to produce two secondary spermatocytes, each with 23 chromosomes (haploid). Just prior to this division, the genetic material is replicated so that each chromosome consists of two strands, called chromatids, that are joined by a centromere.
Answer:
Assertion In the testis, spermatogenesis occurs in the seminiferous tubules and testosterone secretion takes place from the Sertoli cells. Reason Testosterone brings growth and maturation of secondary s3x organs and also the development of accessory s3x characters.

Characteristic #3: Every planet in the solar system has at least one moon.
Characteristic #4: Only a few planets have rings or ice and rock that orbit the planet.
Correct the error in the list of characteristics.
A) There are planets in the solar system with no observable atmosphere.
B) There are planets in the solar system that do not have moons.
C) The surfaces of all planets in the solar system consist of both gas and solid rock.
D) All planets have rings, but you can only see them on a few planets in the solar
system.
Answer:
B!
Explanation:
The list of characteristics has an error in it which includes that every planet in the solar system has at least on moon. Because, there are planets in the solar system that do not have moons. Thus, the correct option is B.
What are the characteristics of planet in the Solar system?A planet is a celestial body that is in an orbit around the Sun. A planet has sufficient mass for its self-gravity to overcome the rigid body forces so that it assumes a hydrostatic equilibrium which is nearly round in shape, and also has cleared the neighborhood around its orbit.
A planet must have three things which includes an orbit and a star in our cosmic neighborhood, like the Sun. A planet must be big enough to have enough gravity to force it into a spherical shape. A planet must be big enough that its gravity cleared away any other objects of a similar size and shape near its orbit around the Sun.
Therefore, the correct option is B.

how do the size and shape of human canines compare with chimp canines
Answer:
Human canines are blunt and small in size, while chimps have big and sharp canines.
Explanation:
Chimps' mouths are larger than humans' mouths. Chimps have a flat palate; and bigger and sharper canines than humans. Also, there is a space between these teeth and the teeth at the front of the mouth. On the other hand, humans' mouths are smaller, which leads to smaller and less sharp canines, and there is no space between these teeth and the teeth at the front of the mouth.
