Answer:
The contraction would increase.
Explanation:
The contraction would increase if the paramecium were placed in distilled water because of the change in the surrounding environment. The contractile vacuole will expel water less frequently because there is higher concentration of water outside the cell whereas the solute diffuses due to lower concentration of salt in the solution. So due to change of environment from saline solution to distill water solution, the contraction increases in the paramecium.
Answer: a) The contractions would increase

It's right.

3. Which parts are located within the chloroplast? (Select all that apply.)
stroma
granum
xylem
phloem
Explanation:
As I think Stroma and granum are the correct answer.
There are two distinct regions present inside a chloroplast known as the grana and stroma. Grana are made up of stacks of disc-shaped structures known as thylakoids. The grana of the chloroplast consists of chlorophyll pigments and are the functional units of chloroplasts.
Which statement best describes the motion of the plates along these boundaries that causes the earthquakes? The plates push apart from each other with no subduction. Subduction occurs with the less-dense plate sinking below the other plate. Subduction occurs with the more-dense plate sinking below the other plate. The plates smash together with no subduction.
Answer:
D). The plates smash together with no subduction.
Explanation:
As per the question, the last statement most adequately demonstrates the movement of plates i.e. 'the plates hit together without any detraction' through concurring boundaries causing the earthquakes to take place. The continuous smashing of tectonic plates with one another leads to the development of a pressure towards both the rock layers by the time this stress is released through a shaky or convulsive movement of the Earth. Thus, option D is the correct answer.

Answer:
A
Explanation:
Evoulousion's meaning is the changing of a species over a period of time.
Answer:
Charles Darwin's theory of evolution states that evolution happens by survival . Individuals during a species show variation in physical characteristics. ... As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve

The muscles in the leg are considered long muscles. As the muscles in the leg contract and relax they work to provide movement. What would happen if the upper leg muscles were damaged?
Answer: if the upper leg muscles were damaged, (You would not be able to extend the leg straight).
Explanation:
The upper leg muscles, which can also be called the thigh, are made up of three sets of muscles which include:
--> the hamstring muscles: These are located at the BACK of the thigh. They are made up of three long muscles which includes the semimembranous muscle, the semitendinosus muscle, and the biceps femoris muscle.
--> the quadriceps muscles: They are located at the FRONT of the thigh. They consists of four individual muscles which includes the three vastus muscles and the rectus femoris.
--> the adductor muscles: They are located at the medial compartment of the thigh and is consist of the following muscles: gracilis, obturator externus, adductor brevis, adductor longus and adductor magnus.
The quadriceps, hamstrings and adductor muscles work together to straighten (extend) and bend (flex) the leg. Therefore when there is damage to the upper leg muscles, you would not be able to extend the leg straight.

Answer:
transcription factor
Explanation:
Transcription is the process by which a specific fragment of DNA (e.g., a gene sequence) is used as template to synthesize an RNA molecule, typically a messenger RNA (mRNA), which is then used to synthesize a protein by a process called translation. Transcription factors are proteins that bind to specific genomic sequences (e.g., promoter sequences) in order to alter the mechanism of transcription. Transcription factors function coordinately to stimulate or inhibit specific cellular processes (e.g., cell division, cell growth, cell migration, etc.) according to the cell type and stage of development. Transcription factors may act alone or form macromolecular complexes that stimulate or block the recruitment of the RNA polymerases (RNA pols), which are key enzymes required for transcribing a fragment of a DNA strand (e.g, a gene) into an RNA sequence during transcription.

What effect does deforestation have on the environment?
A increased oxygen in the atmosphere
B increased carbon dioxide in the atmosphere
c decreased oxygen in the geosphere
D decreased carbon dioxide in the atmosphere
Answer: its definitely B or C i think that it might be C
Explanation:
As more trees are removed there is less trees to remove the Carbon Dioxide from our atmosphere.
This means that there are less trees producing Oxygen which almost all living organisms need to survive which will decrease the amount of Oxygen in The Geosphere
The Geosphere is any of the almost spherical concentric regions of matter that make up the earth and its atmosphere, as the lithosphere and hydrosphere.
