What happens when ionic compounds dissolve in water?
a) Cations and anions are released into the solution
b) They split up H2O molecules into H and O
c) They stick to the wall of the beaker
d) They are transformed into non-metals
Taking into account the definition of ionic compound, the correct answer is option a): Cations and anions are released into the solution.
First, you have to know that an ion is an electrically charged particle.
Ionic bondSo, the ionic bond consists of the electrostatic attraction between ions with charges of opposite sign. This type of bond occurs between the chemical combination of a metal and a nonmetal.
Ionic compoundFinally, an ionic compound is made up of positive and negative ions, held together by electrostatic forces of attraction. Atoms of metallic elements tend to lose one or more electrons when combined with non-metallic atoms, and non-metallic atoms tend to gain one or more electrons.
As a result of this transfer of electrons, the metallic atom becomes a positive ion (called a cation) and the non-metallic atom becomes a negative ion (called an anion).
In other words, an ionic compound is a chemical compound made up of two substances with a significant difference in their electronegativities. It is formed preferably between metals and non-metals.
Ionic compounds dissolve in waterSo when ionic compounds dissolve in water, they separate into cations and anions, electrolytic dissociation occurs. This is because water becomes a conductor of electricity.
In summary, the correct answer is option a): Cations and anions are released into the solution.

You are studying natural selection in a population of small marine invertebrates called isopods that live on pink corals. In this population, isopod body color is controlled by one gene with alternate alleles A and a. Isopods can be red (AA), pink (Aa), or white (aa); body size is controlled by another gene with alternate alleles B and b, and they can be large (BB or Bb) or small (bb). A new predator arrives on the reef that is extremely good at preying on isopods that are large and stand out against the corals on which they live (i.e., red or white individuals). Over time, which genetic individuals would you predict would become more abundant in the population with each subsequent generation?
Answer:
Aa, bb
Explanation:
Recall that this question calls our attention to the theory of evolution as postulated by Charles Darwin. Species that are well adapted to their environment are more likely to survive, reproduce and pass on these favourable characteristics to their offspring.
In this case, the coral reefs are pink and pink Isopod species with small bodies are likely to escape the predators. Hence the genetic combination Aa(pink body) and bb(small body) are more likely to survive and reproduce.

Answer:
Explanation below
Explanation:
There are different form or type of blood group. These include blood group A, B, AB and O.
The blood group AB is usually known as the universal recipient while the blood group O is the universal donor.
A universal donor can donate blood to all other blood groups, while the Universal recipient can receive blood from all other blood groups.
In this case, two patients, one with blood group A and the other with blood group AB, with only one available group A type pint for transfusion. The best thing to do in this case is to give the blood to group A patient and get any other blood group pint of blood for the group AB patient. This is because the blood group AB patient can receive blood from any of the blood groups.

Place the following steps of endomembrane system function in the correct order.
1. Golgi apparatus receives transport vesicles from the RER.
2. Ribosomes on the RER synthesize proteins.
3. Proteins are packaged into transport vesicles.
4. Modified proteins may be secreted from the cell by exocytosis.
5. Proteins are modified by the Golgi apparatus.
A. 2, 4, 3, 1, 5
B. 3, 2, 1, 4, 5
C. 1, 2, 3, 5, 4
D. 2, 3, 1, 5, 4
Answer:
D
Explanation:
The correct option here would be D.
The endomembrane system refers to a group of membrane-based organelles whose primary function is to synergistically work together to modify, package, and transport lipids and proteins. The system includes organelles such as the lysosome, the nuclear envelope, the endoplasmic reticulum, and the Golgi apparatus.
For an endomembrane system function involving a protein, the protein would first of all need to be synthesized by the ribosome - the free ones or the ones attached to the rough endoplasmic reticulum. Thereafter, the synthesized protein would then be folded or packaged into transportable vesicles. The vesicles are then received by the Golgi apparatus which further modifies the proteins before transporting them accordingly.
Hence, the correct order of a typical endomembrane system function would be:
Ribosomes on the RER synthesize proteins.Proteins are packaged into transport vesicles.Golgi apparatus receives transport vesicles from the RER.Proteins are modified by the Golgi apparatus.Modified proteins may be secreted from the cell by exocytosis.Protein synthesis involves transcription and translation. Once the protein is synthesized, it suffers a few modifications in the RER and the Golgi complex, before leaving to its final destiny. The correct option is D. ⇒ 2, 3, 1, 5, 4
Protein synthesis and modificationTranscription ⇒ mRNA syntheisThe first step before protein synthesis begins is to synthesize messenger RNA, mRNA.
This is the coping process of the DNA section for the desired protein, and it happens in the nucleus.
Translation: Cytoplasm stageTranslation takes place when the formed mRNA moves to the cytoplasm through the nucleus membrane pores, and meets a ribosome.
Ribosomes are organelles composed by the association of proteins with rRNA and tRNA. They can be found in the rough endoplasmic reticulum or floating in the cytosol.
While the ribosome reads mRNA strain from its 5´ extreme to 3´, tRNA adds the correct amino acids to build the polypeptide.
Endoplasmic Reticulum StageSome proteins are destined for membrane or exportation. Their synthesis starts in the cytoplasm but finishes in the Rough endoplasmic reticulum.
When the ribosome and the growing molecule reach the RER, the synthesizing protein keeps enlarging forward the reticulum lumen.
When the new polypeptide synthesis is complete, it is released into the reticulum lumen.
The endoplasmic reticulum is in charge of protein folding, maturation, and transport, especially those destined for secretion. It produces the latest protein modifications after transduction and initiates the glycosylation process.
The new proteins get packaged into vesicles that carry them to the Golgi complex.
Golgi complex stageOnce the protein synthesis in the endoplasmic reticulum is over, these molecules are packaged into vesicles and sent to the Golgi complex.
In the Golgi complex, proteins suffer their final association with carbohydrates and lipids to originate glycoproteins and glycolipids.
Destiny stageGlycoproteins and glycolipids are packaged again into new vesicles that drive them to their final destiny.
Proteins destined for exportation are packaged and sent from the Golgi complex to the cell membrane into vesicles.
When the secretory vesicle reaches the target, its membrane fuses with the cell membrane, releasing its content to the extracellular space. This secreting process is known as exocytosis.
According to this resume about protein synthesis, we can say that the correct order is option D. ⇒ 2, 3, 1, 5, 4
2. Ribosomes on the RER synthesize proteins.
3. Proteins are packaged into transport vesicles.
1. Golgi apparatus receives transport vesicles from the RER.
5. Proteins are modified by the Golgi apparatus.
4. Modified proteins may be secreted from the cell by exocytosis.

Where does the oxygen needed for aerobic respiration come from?
Which is FALSE? First exclude the four correct answers. Which is FALSE? First exclude the four correct answers. The leaves are only a small part of the plant and must produce enough energy-rich sugars to support all non-green parts like roots or flowers. Only when overall photosynthetic activity is greater than overall respiration activity of the whole plant can the plant accumulate biomass and grow. Sugar produced in photosynthesis must support the plant’s energy needs both day and night. Leaves perform more photosynthesis than respiration because they don’t have mitochondria. In trees that drop their leaves over the winter, some sugar produced in one year is stored in stems or roots and fuels the production of new leaves in the next year.
Answer:
1 .The leaves are only a small part of the plant and must produce enough energy-rich sugars to support all non-green parts like roots or flowers --TRUE.
2.Only when overall photosynthetic activity is greater than overall respiration activity of the whole plant can the plant accumulate biomass and grow--TRUE.
3.Sugar produced in photosynthesis must support the plant’s energy needs both day and night TRUE.
4. In trees that drop their leaves over the winter, some sugar produced in one year is stored in stems or roots and fuels the production of new leaves in the next year TRUE.
The statement that is FALSE is
Leaves perform more photosynthesis than respiration because they don’t have mitochondria.
Explanation:
The statement that is FALSE is
Leaves perform more photosynthesis than respiration because they don’t have mitochondria and it is false because leaves contain both mitochondria and chloroplast.
The plants leaves have chloroplast, an organelles that house the chlorophyll which help its to photosynthesized. Plants also require ATP to carry out cellular activities and need oxygen to breakdown sugars produced from photosynthesis to produce ATP, because of this, they need mitochondria to achieve this and that is why they have mitochondria.
In the night, when there is no sunlight, plants perform respiration, they use oxygen to break the sugars they produced in order to produce ATP.

Answer:
-Viruses cannot replicate.
-Viruses do not need to consume energy to survive or regulate its own temperature.
Explanation:
<3
Viruses are not able to replicate or carry out any of the functions of living cells on their own. They rely on the machinery of the host cell in order to replicate and produce new viruses, and they are not able to carry out functions such as metabolism, growth, or reproduction on their own.
Why viruses are considered non-living?Viruses are much simpler in structure than bacteria and other living cells. They do not have a true cell structure or any of the characteristic cell organelles found in living cells, such as a nucleus, mitochondria, or endoplasmic reticulum. Instead, they are composed of a small piece of genetic material (either DNA or RNA) surrounded by a protein coat.Learn more about viruses, here:
