What lighting direction can make a flower’s petals almost glow?

Answer:

The correct answer is back lighting.

Explanation:

Light direction is the primary direction of the light which can hit the flower.

Backlighting is a design technique which helps the flowers shine in a garden using sunlight during sunrise or sunset or in photo-studio labs.

This technique helps to emphasize the transparency of the petals when intense light is used for most of the flowers while soft and low light for a few flowers. In gardens also during the golden hours of the day, this technique is helpful.

Thus, backlighting is the correct answer.

Do you think humans will ever be able to forecast severe weather with 100% accuracy? What challenges do we face in developing technology that can do so? Besides forecasting tools, what other technology is needed to prevent severe storms from causing disasters? Do you think all countries have the financial capability to support the development and operation of these technologies? If not, do you think there is an ethical obligation for countries with more financial resources to help poorer countries access these technologies?

First of all nature, in most cases is unpredictable, so it would be really difficult to forecast weather with complete accuracy. Governments could start to educate people on safety measures and establish the necessary infrastructure to combat calamity. All countries are financially capable because they are all vulnerable and it should be a priority in any case. And wealthier countries, somewhat have the obligation to help out.

QUESTION POSTED AT 21/01/2020 - 01:46 AM

According to Darwin's theory of natural selection, individuals who survive are the ones best adapted for their environment. Their survival is due to A. possession of adaptations developed through use. B. possession of inherited adaptations that maximize fitness C. lack of competition within the species D. choices made by plant and animal breeders

The correct answer is B. possession of inherited adaptations that maximize fitness

Darwin describes evolution through the mechanism of natural selection which is an explanation of how populations could evolve so that they became better suited to their environments over time.

Because resources are limited in nature, only those organisms with heritable traits (adaptations to the environment) that favor survival and reproduction will tend to survive and leave more offspring than other organisms.  This will cause the increase in the frequency of those traits over generations. That’s the way natural selection works, it causes populations to become adapted to their environments over time. Natural selection depends on the environment (it favors traits that are beneficial for the specific environment, that trait might be harmful in some other environment)  and requires existing heritable variation in a group (there must be variation, the difference between the individuals).

An object has a force of 10 newtons from the right and 17 newtons from the left. Once the object starts moving toward the right, an additional force of 7 newtons is applied from the right. What can you conclude about the direction of motion of the object after the application of the additional force?

Answer;

The object will not move in either left or right direction, because the net force will be Zero.

Explanation;

  • Initially, the object experienced an unbalanced forces, 10 N from the right and 17 N from the left, which resulted to a net force of 7 Netwons, and thus the object moved towards the right.
  • Addition of a force of 7 Newtons from the right, resulted to balanced forces from both direction, thus the object stopped moving in either direction as the net force became zero.
  • An unbalanced force acting on an object makes the object to move, change direction or its speed.  Balanced forces creates a zero net force making the object to have zero acceleration or stop motion.

Which of the following statements is true for a cell placed in beaker containing an isotonic solution? A)Water molecules flow from the cell into the beaker. B)Water molecules flow from the beaker into the cell. C)Water molecules flow in both directions at the same rate. D)There is no movement of water molecules.

The answer is C)Water molecules flow in both directions at the same rate. In a hypotonic solution, the water concentration of the cell's cytoplasm is lower than that of the hypotonic solution. In a hypertonic solution, the water concentration of the cell's cytoplasm is higher than that of the hypotonic solution. In, an isotonic solution, there is a balance in the water concentration between the cell's cytoplasm and the solution. Thus, water molecules flow in both directions at the same rate.

Lines of evidence from many fields of study, from fossils to DNA sequences, have been important in developing evolutionary theory. Why is it important to have supporting evidence from a variety of fields?

Whenever any theory is given then it is not just given by one observation, there are many observations on which a single theory is given. There can be different kinds of observations and evidences from a variety of fields to support a theory so that the result is accurate and precise.

Whenever any experiment is done it is also done with a large sample space so the results are correct and accurate.

That is why the theory of evolution has evidences from different fields like from fossils and from DNA sequences, phylogenetic tree and many more places.
