The answer is endoplasmic reticulum. There are two types of the organelle. The rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER). The RER has ribosomes attached to its outer membrane hence mainly folds, modifies and transports proteins. SER, on the other hand, is significant in the modification and transportation of lipids.
Answer:
inherited condition in which there aren't enough healthy red blood cells to carry adequate oxygen throughout your body. these irregularly shaped cell can get stuck in small blood vessels which can slow down or block blood flow and oxygen.
Explanation:
ANSWER: (A) All species of Plasmodium can cause relapses.
EXPLANATION: All species of Plasmodium can cause relapses is FALSE.
Based on series of research on malarial parasites, only two species of Plasmodium can cause relapses (P. vivax and P. ovale.).
These species of plasmodium are known for causing relapses i.e the reappearance of parasitemia after treatment of affected individuals.
However, it is assumed that the subset of the parasites that caused the primary infection caused the relapses.
Furthermore, individuals who are cured of their blood stage may have a subsequent infection without reinfection (relapses). This is caused by the presence of the latent (exo-erythrocytic) stage, which exhibit dormancy in the body.
Answer:
Plankton and Algae
Explanation:
Adult zebra mussels feed by filtering large amounts of plankton and detritus from the water. Each mussel can filter one liter of water per day! Zebra mussels thrive in nutrient-rich water which supports healthy populations of plankton.
Answer:
Crossing over is a process in which exchange of segments occur between two non sister chromatids.
Explanation:
Crossing over is a process in which two non-sister chromatids of homologous chromosomes exchange the segments of genetic material with each other during meiosis. Due to this process, variation occurs in an organism.
Independent assortment is a process in which different alleles are sorted to different gametes which occurs independently and does not effect one another. This process occurs in metaphase of meiosis l.
Joining of sex cells is a process in which sex cells of male and female join together formed a zygote which turn into a new organism. These sex cells are formed during meiosis which are haploid in nature.
Mutation and crossing over are the factors that cause inherited genetic variations within populations.
Sudden change occurs in the genes of an organism due to the exposure of the cell to radiation or chemicals.
