(WILL GIVE BRAINLIST) A student investigated the effect of root space on plant growth. The student grew two groups of plants of the same variety. Both groups received the same amount of water and sunlight and grew in the same type of soil. The plants in Group A were grown in cube-shaped containers that were 3 centimeters deep. The plants in Group B were grown in cube-shaped containers that were 10 centimeters deep. The table shows the student's observations (picture provided). What was the effect of root space on plant growth based on the student's investigation? Use the data from the table to support your answer. Explain how you would know whether this effect was likely due to environmental or genetic factors.

Briefly explain how specific protein molecules change over many years resulting in evolution.
Answer:
Protein evolution is inescapably tied to changes and selection of DNA polymorphisms and mutations because protein sequences change in response to alterations in the DNA sequence.
Amino acid sequences and nucleic acid sequences do not mutate at the same rate.

Give a short explanation on Osmosis and Diffusion?
Answer:
Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution.
Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.

If dna ligase was nonfunctional, what would be a likely consequence?.
Answer:
DNA ligase is a specific type of enzyme, a ligase, (EC 6.5.1.1) that facilitates the joining of DNA strands together by catalyzing the formation of a phosphodiester bond. It plays a role in repairing single-strand breaks in duplex DNA in living organisms, but some forms (such as DNA ligase IV) may specifically repair double-strand breaks (i.e. a break in both complementary strands of DNA). Single-strand breaks are repaired by DNA ligase using the complementary strand of the double helix as a template, with DNA ligase creating the final phosphodiester bond to fully repair the DNA.

What is important in Hubble's discovery about the red shift in the spectra of galaxies? a. It proves the Big Bang theory. b. It suggests the existence of black holes. C. It suggests that the universe is expanding. d. It suggests that the universe is contracting.
Answer:
c
Explanation:
Hubble's brilliant observation was that the red shift of galaxies was directly proportional to the distance of the galaxy from earth. That meant that things farther away from Earth were moving away faster. In other words, the universe must be expanding.

Early hominid fossils were examined and scientists concluded these hominids exhibited bipedalism. How could they tell that by looking at their skeletal remains?
Answer:
The shape of the thigh bones confirms Orrorin was bipedal. The earliest hominid with the most extensive evidence for bipedalism is the 4.4-million-year-old Ardipithecus ramidus.
Explanation:
Major morphological features diagnostic (i.e., informative) of bipedalism include: the presence of a bicondylar angle, or valgus knee; a more inferiorly placed foramen magnum; the presence of a reduced or nonopposable big toe; a higher arch on the foot; a more posterior orientation of the anterior portion of the iliac
Early hominid fossils were examined and scientists concluded these hominids exhibited bipedalism. This confirms that they belong to Orrorin.
The shape of the thigh bones of the hominid fossil confirms that it belongs to Orrorin species which was bipedal. The earliest of the hominid fossils with the most extensive evidence for bipedalism is almost about 4.4 million year old Ardipithecus ramidus.
Major morphological features which are diagnostic or informative of bipedalism in the species include the presence of a bicondylar angle, or the valgus knee. It is a more inferiorly placed foramen magnum and is the presence of a reduced or the non-opposable big toes. A higher than normal arch on the foot and a more posterior orientation of the anterior portion of the iliac

During the second stage of the inflammatory response, what do neutrophils accomplish when they migrate to areas of damaged tissue
We can confirm that during the second stage of the inflammatory response, after migrating, neutrophils accomplish phagocytosis and release of reactive chemicals and proteases.
What are neutrophils?A neutrophil is a white blood cell from the granulocyte family. They combat foreign invaders in the body. After migrating, these cells will engulf unwanted substances with their membrane and destroy them, a process is known as phagocytosis, as well as release chemicals and proteases to aid in the defense of the organism.
Therefore, we can confirm that during the second stage of the inflammatory response, after migrating, neutrophils accomplish phagocytosis and release of reactive chemicals and proteases.
