Select all of the following that are a result of heating up a solution?
Molecules will move faster
Molecules will slow down
Molecular movement will not change
More collisions will occur between molecules
Answer:
a
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
The results of heating up a solution are:
Molecules will move faster
More collisions will occur between molecules
According to the kinetic molecular theory, when a solution is heated up:
The temperature of the solution risesThe attractive forces binding the molecules weakensThe speed of the molecules increases. This means that the molecules move faster than before The rate of collision between the molecules increases. This is because of an increase in the Kinetic Energy possessed by the molecules as the temperature risesTherefore, among the given options, the results of heating up a solution are:
Molecules will move faster
More collisions will occur between molecules

Darwin's experiments are just one way to study phototropism. A student wants to investigate the effects of phototropism in bean plants. She places a light source directly above one plant, at a forty‐five degree angle to another, and at a ninety‐degree angle from the third.
What is her independent variable?
What is a hypothesis she might write for her experiment?
Answer:
Her independent variable is the light source and her hypothesis is what YOU think might happen
Answer:
The independent variable is what is being changed or altered in the experiment (light position), the dependant variable is what is altered or changed by the independent variable (plant).
Explanation:
Consider what is being changed in this experiment to investigate the effects? The plant itself is not changed by the experiment but the positioning of the light source is. That is your independent variable. The plant may change as a result of the independent variable but isn't being altered or changed as part of the method (dependent).
What is a hypothesis she might write?
Consider a hypothesis as a prediction. Researchers come up with their hypothesis based on the information they already know. So to write your hypothesis think about what you already know about phototropism. What do you think will happen to the plant in relation to the positioning of the lamp? Will the plant not move? Will it bend or move to face the lamp?

What is apical meristematic tissue? And its function
Answer:
Apical meristematic tissue and its function the apical meristem, also known as the “growing tip,” is an undifferentiated meristematic tissue found in the buds and growing tips of roots in plants. Its main function is to trigger the growth of new cells in young seedlings at the tips of roots and shoots and forming buds.
I hope my answer will help you,God blessed youIn order from smallest to largest, the ecological levels of organization are
A: biome, ecosystem, community, population, individual
B:community, individual, population, ecosystem, biome
C: individual, population, ecosystem, community, biome
D: individual, populations, community, ecosystem, biome
Answer:
D: individual, populations, community, ecosystem, biome
In order from smallest to largest, the ecological levels of organization are individual, populations, community, ecosystem, biome. So, the correct option is (D).
What is an Ecosystem ?Ecosystems are the complex living organisms and their physical environment and all their concerned correlation in a specific unit of space.
An ecosystem can be classified as
1.Abiotic constituents
It consists of minerals, climate, soil, water, sunlight, and all other non living materials.
2. Biotic constituents
It includes all its living organisms.
By combining these constituents together generates two important forces:
The flow of energy from the ecosystem The galloping of nutrients within the ecosystem.
Ecosystems have varied sizes like some are tiny enough to be encompassed within single water droplets while others are big enough to embody entire topography and regions.
Organic matter engendered by autotrophs directly or indirectly bolster heterotrophic organisms. Heterotrophs are the consumers of the ecosystem which cannot make their own food. They utilize, reorganize, and finally decompose the complex organic substance made up from autotrophs.
Thus, in order from smallest to largest, the ecological levels of organization are individual, populations, community, ecosystem, biome. So, the correct option is (D).

Which of the following is most likely an example of genetic drift resulting from the founder effect?
Answer:
An example of genetic drift resulting from the founder effect, of the available answers listed below, would most likely be a situation in which a population commonly expresses traits that are otherwise rare in the species. An example of this might be an animal with longer limbs than other members of the same species - there have been real-life examples of this studied with lizards.

Explanation:
Emission lines are lines that are made when wavelengths of light are given off by cooling gases.
O True
O False
Answer:
Its FALSE on edge
Explanation:
When cooling gases emit light wavelengths, lines known as emission lines are created. The first people to notice constellations were the ancient Romans and Greeks.
What Emission lines that are made when wavelengths light?Monochromatic light has a single wavelength and is generated by lasers, which exploit transitions between two atomic energy levels to generate light with an extremely restricted range of wavelengths.
While emission lines refer to the lines of light produced by burning hot gas, absorption lines refer to the tendency of cool ambient gas to absorb the same lines of light.
Some light at specific wavelengths is scattered when it travels through the atmosphere's gas, producing darker bands.
Therefore, It is false that Emission lines are lines that are made when wavelengths of light are given off by cooling gases.

someone answer these 2 for me
Answer:
F=dominant, 6 fingers
f= reccessive, 5 fingers
Ff= 6 fingers( contains dominant gene)
if you combine Ff and Ff you get:
25% FF (6 fingers)
50% Ff (6 fingers)
25% ff ((5 fingers)
so only 25% will have 5 fingers (normal)
Answer2:
Dominant=normal hearing
Recessive= deafness
If one parent is RR and the other Rr, the offspring will be:
50% RR
50% Rr
so all the offspring will have normal hearing, and there is 0% of deafness.
