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.what do you think is a way for geologist to locate ore bodies? justify your answer

5. Which of the following statements best describes the response of finches to drought on the Galapagos Islands?
O A During drought, individual finches saw that large, hard seeds were the only available food. To crack these harder seeds, individual finches grew their beaks
larger, resulting in an increased average beak depth
OB During drought, finches struggled to open harder seeds All the scraping and pecking wore down their beaks, resulting in a reduced average beak depth
OC. During drought, only finches with larger-than-average beaks were able to crack the hard seeds that were available. These finches survived while smaller-
beaked finches died, resulting in an increased average beak depth in the population
O D. During drought, finches with smaller beaks (and smaller bodies) had an advantage. With reduced food supplies, larger finches (with larger beaks) were
more likely to starve. The result was a decrease in average beak depth
Answer:

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.

What is the purpose of Mitosis? *
A. To produce an egg and a sperm cell.
B. To produce a new organism (like bacteria).
C. To produce a new cell (NOT a new organism).
D. To differentiate.
Answer:
C.
Explanation: Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.
Hope this helps! Have a nice day!
Answer:
C. to produce a new cell
Explanation:
Mitosis consists in replicating the genetic material of a mother cell in order to make two identical daughter cells; this is a diploid process. In order to make an egg or sperm cell and eventually a new organism, the correct process would be meiosis, since it combines the DNA between two cells and it is an haploid process.

All three vehicles have a constant acceleration.
All three vehicles have a constant acceleration.
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.

What will happen to plants that are kept in the dark?
Answer:
they die
Explanation:
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.

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.

How would you describe the difference in the motion of the sled from when the people first start pushing to when the sled is halfway down the hill?
The difference in the motion of the sled from when the people first start pushing to when the sled is halfway down the hill will be described as after starting off much more slowly, it picks up speed significantly by the bottom of the slope.
At the top of the hill, a sled has pushed itself. If we then apply a tiny push, the sled's initial speed will be 0, indicating that the sled's only starting energy is gravitational potential energy. Therefore, assuming there is no friction, the sled's greatest height will be equal to its initial brightness. So the slides will never make up for a bump that is higher than its starting point. The sled's highest point is equal to its initial height because of the rule of conservation of mechanical energy. The sled will never make it up if they restrict it if the friction is seated.
