Malaria is transmitted when an infected female Anopheles mosquito. These are the only mosquitos that can spread malaria. It can also get transmitted when the mosquito drinks from an infected person, and thus they pass it on to their next victim.
Answer;
-Endocytosis
Explanation;
-Endocytosis includes; phagocytosis, pinocytosis, and receptor mediated: Endocytosis brings substances into the cell, plasma membrane surrounds the substances to be taken in, encloses them in a membrane-bound sac (vesicle) and brings them into the cell
-Phagocytosis: endocytosis of large solid particles (“cell eating”)
-Pinocytosis: endocytosis of extracellular fluid that contains dissolved solutes (“cell drinking”)
-Receptor-mediated: highly selective, ligands bind to specific receptor proteins on the plasma membrane and are then taken into the cell
-Exocytosis: the reverse of endocytosis: substances are removed from the cell; vesicles fuse with plasma membrane and release their contents into the extracellular fluid; important in nerve cells to release neurotransmitter and secretory cells to release cell products (ex. digestive enzymes, protein hormones).
Answer:
Non-coding DNA regions play important roles in regulating transcriptional activity by encoding different types of non-coding RNAs (ncRNAs), acting as scaffold attachment regions, acting as enhancer specific regions, etc.
Explanation:
Historically, it had been believed that non-coding DNA sequences were 'junk DNA' since they don't encode for proteins (beyond the sequences that are transcribed into functional non-coding RNAs, i.e., transfer RNA and ribosomal RNA). However, in the last years, it has been shown that non-coding DNA sequences play critical roles in regulating gene expression and genome function. For example, evolutionary conserved non-coding RNAs (ncRNAs) with regulatory roles on gene expression such as, for example, long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) have been mapped in non-coding DNA sequences, thereby evidencing the functional significance of these regions. In consequence, the conservative nature of certain non-coding DNA sequences evidence that mutations in such regions may have significant deleterious effects, and thereby they could have a negative impact on the fitness of the individual.
The answer is B.minerals vitamins and water
Explanation: long-tailed helps a lizard with balance. It provides a fat reserve for the lizard in times of starvation. A lizard uses its tail to communicate its feelings and its social status. Lizards detach their tails as a defense mechanism.
