1- The nucleus is involved in teh formation of mRNA which is used to send message to the ribosome about what kind of protein is used to synthesize
2- and 3- Endoplasmic Reticulum(ER), Rough ER has the ribosomes on their surface, which are involved in teh formation of protein.
4- They are the vesicles from the RER
5- It is the Golgi body or Golgi complex or golgi apparatus or simply Dictyosomes. They are used in the packaging of the protein, gives the protein finishing touch before they move out from the cell. They like ER has canalicular system with sacs but they are parallel arranged, flattened membrane bounded with lack of ribosomes. They have two faces. One is receiving face which receives the vesicles from the Endoplasmic reticulum called cis face. The other is shipping face which releases packaged protein into the cytoplasm ready to go outside from the cell.
6and 7- They are the vesicles from the golgi bodies.
8- Vesicle diffuses with the cell membrane through which the protein is moving out from the cell, the process called exocytosis.

Answer:
B)
Anaerobic respiration
Explanation:
All living organisms require energy for survival. They obtain this energy via the process of cellular respiration, where they breakdown the energy in their ingested food. However, the process of cellular respiration can either be aerobic (with oxygen) or anaerobic (without oxygen).
Anaerobic respiration is carried out by organisms who do not require OXYGEN for the process. This is the case of the bacteria described in this question which survive in a puncture wound that has healed on the outer surface of the skin in an environment without oxygen present. The type of respiration carried out by this bacteria is ANAEROBIC RESPIRATION.
Explain what occurs between water molecules in hydrogen bonding
Answer:
The molecules are attracted to their less negative side.
Explanation:
A water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structure is bent. This is because the oxygen atom, in addition to forming bonds with the hydrogen atoms, also carries two pairs of unshared electrons. All of the electron pairs—shared and unshared—repel each other.
The Oxygen in the water molecule will share or the hydrogens lone atom leaving the hydrogen with a more positive charge like in the picture I've added. This happens with all water molecules leaving the oxygen with more electrons and ultimately the more negative side. And positive and negative forces attract, so the now "positive" hydrogens will bond with the now "negative" oxygens. They form bonds using polarity, and use a very strong dipole dipole effect.

Many features distinguish modern humans from the nonhuman apes. However, only bipedalism and non-honing canines define hominins as a group. Identify the reasons why?
1) The proper taxonomic groups are most times always defined by the traits,these traits are the ones that are shared among members of the group eventhough they aren't found in species that are closely related.
2) The two traits are all common as they arise in the ancestors of all the hominins, however,they are not found in the nonhominins apes
3) The evolution of these hominins involved several changes that are different and that happened at different times,and only two of these features,out of all that we have evolved early enough to actually apply to all the hominins.
What is required for LIGHT DEPENDENT reactions to occur in plants?
Answer: In light-dependent reactions, the energy from sunlight is absorbed by chlorophyll and converted into chemical energy in the form of electron carrier molecules like ATP and NADPH. Light energy is harnessed in Photosystems I and II, both of which are present in the thylakoid membranes of chloroplasts.
Explanation:
The light dependent reaction mainly include sunlight, chlorophyll, thakaloids.
Light-dependent reactions
When sunlight hits a molecule of chlorophyll.The excited photon that are present in light also excites an electron which leaves the chlorophyll molecule.These electron then travel travels along the thylakoid membrane via a series of carrier proteins.This reactions convert light energy into chemical energy, also known as photosynthesis.
Plant by the process of photosynthesis collect energy from the sun and break down water molecules to produce ATP and NADPH.
These two energy-storing molecules are then used in the light-independent reactions and maintain the cycle. some of these energy get used by the plants for make the food.
Therefore, the light dependent reaction mainly include sunlight, chlorophyll, and thakaloids.

Which of these factors is involved in earthquake formation?
plates getting larger
rocks breaking
stress that decreases
faults that remain stationary
Answer:
rocks breaking
Explanation:
Breaking rocks is one the factors that is involved during the formation of an earthquake. As rock breaks, there is a sudden release of energy into the surrounding.
When a rock breaks, it is said to be fractured. Such rock fracturing that involves movement of the earth leads to the formation of earthquake. In this process, there is a sudden burst of seismic waves into the environment. Surface waves will cause the damage on the earth surface. The basis of earthquake formation is ability of rocks to break and release a sudden burst of energy.Answer:

How does surface tension force the surface of water to curve
Answer:
the molecules at the surface are being pulled by other molecules. The pulling forces the water to curve. ... The positive hydrogen ends of one water molecule attract the negative oxygen ends of nearby water molecule.
Explanation:
Surface tension forces the surface of water to curve due to its tendency to reduce the surface area of water.
The surface tension of a liquid is in itself a tangential force acting parallel to the surface of the liquid due to the cohesive force of attraction between the molecules of the liquid.
The highly cohesive nature of water molecules means that the molecules at the air/water interface are more stuck together, creating elastic-like surface tension on the water. Thus, the water surface curves inward forming a concave shape.
In other words, the cohesive force of water molecules causes surface tension which in turn causes the surface area of water to reduce or curve inward.

If a DNA sequence is A-T-G-A-C, write the sequence of base pairs that would pair with it.
Answer:
T-A-C-T-G
Explanation:
Deoxyribonucleic acid, widely known as DNA, is the genetic material in living cells. It is a double-stranded molecule, with each strand arising from the pair of nucleotide monomers that forms its structure. In the DNA, four nucleotides exist namely: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
These four bases occur in different combinations to form a sequence that makes up each strand of the DNA. However, each nucleotide pairs with one another using the COMPLEMENTARY BASE PAIRING RULE, which states that Adenine will always hydrogen bond with Thymine, while Guanine will always hydrogen bond with Cytosine i.e. A-T, G-C.
Based on the above, a DNA strand with sequence: A-T-G-A-C will pair with another DNA strand with sequence: T-A-C-T-G.
Deoxyribonucleic acid is an essential molecule that comprises nucleotides purines and pyrimidines.
The six-membered nitrogen-containing ring joined with the imidazole ring is called purines whereas, the pyrimidines are the six-membered nitrogen ring.Purines ascertained in the DNA and RNA are adenine and guanine.Pyrimidines found in the DNA are cytosine and thymine whereas, in the RNA cytosine and uracil is found.The sequence of the base pair formed from the DNA sequence
A-T-G-A-C will be:
T-A-C-T-G
The adenine always base pairs with thymine.The purine guanine always pairs with the pyrimidine cytosine in the case of DNA sequences.
Therefore, the sequence formed will be T-A-C-T-G .
