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

Answers

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 rises

Therefore, among the given options, the results of heating up a solution are:

Molecules will move faster

More collisions will occur between molecules

All eukaryotic cells contain at least one Golgi complex, typically located in the cytoplasm and near the endoplasmic reticulum.
Which of the following best describes a process that occurs within the Golgi complex?

Answers

Answer: Enzymatic modification of newly synthesized integral membrane proteins

Explanation: got it right for AP Bio.

The correct answer that describes the process that occurs within the Golgi complex is the enzymatic modification of newly synthesized integral membrane proteins.

Once protein is synthesized, they undergo folding and repackaging within the endoplasmic reticulum before they are transported to the Golgi apparatus/complex.

Within the Golgi complex, the protein is modified enzymatically and encased in vesicles. It is then transported to the cell membrane where they are utilized as integral protein.

So, basically, the statement that best describes the process that occurs within the Golgi complex is the enzymatic modification of newly synthesized integral membrane proteins.

someone answer these 2 for me

Answers

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.

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?

Answers

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?

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).
