Answer:
See Below.
Explanation:
The key word here is net. The net movement has reached zero when a system is in equilibrium but there are still motion's going back and forth due to statistics and just random brownian motion.
Think of it this way, if there are 100 people walking forwards in a crowd but 2 are moving against the crowd, the net movement is still forwards because the bulk of people are going in that direction. However, there are still 2 people moving against.
Same here, if we are talking about a diffusion, let's say in the case of osmosis, if most of the solute is moving across a membrane then we'd say its net direction is that way but that doesn't mean that there aren't processes happening in the other direction. Water molecules in osmosis mostly diffuse, chemically speaking (because you can say this biologically in a different way), from the probability of water molecules colliding with each other and passing the membrane so even if there is a net movement in a certain way their random motion can make them go to the other side just as well. If the fact that motion stops at equilibrium were the case a lot of systems, both chemical and biological, would not exist as we know it.
Think net = bulk NOT total or entire.
When the net movement is Zero at equilibrium ; An insignificant number of molecules are still moving below
When diffusion reaches equilibrium most of the molecules moving from the areas of higher concentration to areas of lower concentration will stop moving, but a negligible number of molecules will continue to move due to random Brownian motion.
When we say the net movement of molecules at equilibrium is zero it is because majority of the molecules have stopped moving and not all the molecules therefore there will be an insignificant movements of molecules still occuring.
Hence we can conclude that When the net movement is Zero at equilibrium ; An insignificant number of molecules are still moving below

Which of the following would not be considered an observation in terms of the scientific method? A. tasting a pasta sauce after adding a new ingredient B. looking at a blood sample through a microscope C. a dog buries a bone in the backyard D.listening to bats of different materials hitting a baseball
Answer:
C. a dog buries a bone in the backyard
Explanation:
A dog burying a bone in the backyard is not an observation in terms of scientific methods.
Observation is the process of acquiring data about a phenomenon under study.
Most times, senses are used in making observations. Our sense of taste, hearing, sight etc. comes handy when making observation.
Also, we can use some specialized equipment to make observations.
A dog burying a bone in the backyard is not an observation. None of the senses nor instruments are used to gather any relevant information.Rainforests around the world are being cleared at an alarming rate to make room for new communities, agriculture, mining, and roads, and to provide lumber for construction and furniture. How might the destruction of rainforests affect the balance of gases in Earth's atmosphere?
This question is incomplete because the options are missing; here is the missing section:
How might the destruction of rainforests affect the balance of gases in Earth's atmosphere?
by increasing carbon dioxide and decreasing oxygen
by increasing carbon dioxide and increasing oxygen
by decreasing carbon dioxide and increasing oxygen
by decreasing carbon dioxide and decreasing oxygen
The answer to this question is by increasing carbon dioxide and decreasing oxygen.
Explanation:
Rainforests have a vital role on Earth because these regulate the levels of oxygen vs carbon dioxide. This is because plants including trees, grasses, shrubs, etc. require carbon dioxide as part of the photosynthesis process, and they release oxygen at the end of the process. In this way, rainforests reduce the amount of carbon dioxide and increase oxygen.
In this context, deforestation or the destruction of rainforest for mining, roads, etc. implies there are fewer plants, and therefore, less carbon dioxide is being used and less oxygen is released. This causes an increase in carbon dioxide and a decrease in oxygen.

A. Natural selection resulted in a larger species of chicken.
B. Artificial selection created a larger breed of chicken.
C. Mutations occur less frequently in chickens than they did a century ago.
D. Grocery stores used to sell younger chickens.
Answer:
B, artificial selection resulted in a larger species of chicken.
Explanation:
People breed the largest animals (in this case chickens) or plants to improve agriculture.
Hope this helps! ;)
The average size of grocery store chicken has more than doubled in the past century because artificial selection created a larger breed of chicken. The right option would be B.
Artificial selection refers to deliberate actions by humans to selectively breed organisms based on desired traits.
Because big size chickens are desirable for their meats, breeders and genetic engineers would select this trait and favors it over other alternate traits using appropriate scientific procedures (such as controlled mating). Thus, chicken with undesirable traits gradually fades off the population while those with desirable traits are made to thrive.

The nucleus is surrounded by a membrane. This membrane has pores that enable the nucleus to carry out one of its functions. What do these pores allow to happen?
A) nutrients that are stored in the nucleus to enter the cytoplasm
B) proteins that are made in the nucleus to pass into the cytoplasm
C) waste substances to enter the nucleus
D) genetic information to pass from the nucleus to the cytoplasm
Answer:
D
Explanation:
The nucleus contains the genetic information of the cell. When the cell needs instruction to make protiens, Rna carries those instructions out of the cell because DNA is too large to fit through the pores. Proteins are made in the ribosomes.

The pickup truck is the only vehicle accelerating.
The pickup truck is the only vehicle accelerating.
The minivan and sedan are both changing veloc
Answer:
The pickup truck is the only vehicle accelerating.
Explanation:
Acceleration refers to the change in velocity per unit time which means that when the velocity changes, acceleration will be produced and if there is constant velocity of a vehicle so the acceleration will be zero. All three vehicles have same velocity of 15 m/s but the truck has no uniform velocity which means acceleration is produced in the truck while no acceleration is formed by three vehicles.
Answer:
The pickup truck is traveling on a curve in the road
Explanation:
Common sense! The truck is traveling on a curve and therefore will have a change in velocity.

Why is it important for gametes to be haploid cells?
The reason why it is important for gametes to be haploid cells is because: when the sperm and the egg fuse together the living sex cells will have 46 chromosomes.
Gametes are also referred to as sex cells and they can be defined as the reproductive cells in a living organism.
Generally, the male reproductive cell is known as a sperm while the female reproductive cell is known as an egg.
Since gametes are reproductive cells or sex cells, they are typically made up of haploid set of chromosomes.
Basically, it is very important for gametes to be haploid cells so that when the sperm and the egg fuse together, the living sex cells will have a total of 46 chromosomes.
