The stem is the part of the plant which contains vascular tissue. or the piping, of the plant
Answer:
True
Explanation:
In biology or animal behavior, the term cuckold refers to the act of invading a strange net. The term might be applied to different species that parasite other species. A very well known example is the cuckoos bird.
The Cuckold bees or cuckoo bees are many parasitic species belonging to the Apoidea taxon that characterize for invading nests of other bees.
Females lay their eggs in the cells of the host nest. Depending on the species, the intruding female might kill the owner larvae of the cell, or the emerging parasitic larvae is the one that can destroy the host using their highly developed mandibles as weapons.
As they develope, foreign larvae feed on the foodstuffs that the female owners of the nests bring for their own offspring.
Answer:
d. DNA polymerase begins adding nucleotides at the 5' end of the template
Explanation:
Polymerase DNA always works in one direction, synthesizing the new 5' to 3' oriented chains and adding nucleotides to the 3' end of a new synthesis chain by forming phosphodiester bonds between the phosphate of a nucleotide and the sugar of the anterior nucleotide.
Because DNA polymerase only acts in a 5' to 3' direction, replication along a chain, the leading chain, occurs continuously. The synthesis of the opposite chain, the delayed chain, occurs discontinuously because the DNA polymerase must wait for the replication fork to open. Over the delayed chain, short segments of DNA called Okazaki fragments (named after Reiji and Tsuneko Okazaki, the scientists who discovered these fragments) are synthesized as polymerase DNA works out of the replication fork. Ligase DNA catalyzes the covalent bonds between Okazaki fragments in the delayed chain to ensure there are no gaps in the phosphodiester skeleton. Finally, the first ones are removed and these gaps are filled by the DNA polymerase.
Answer:
Carbon dioxide can be transported through the blood via three methods. It is dissolved directly in the blood, bound to plasma proteins or hemoglobin, or converted into bicarbonate. The majority of carbon dioxide is transported as part of the bicarbonate system. Carbon dioxide diffuses into red blood cells.
Explanation:
Answer: a) relies on the uptake of an external signal molecule from the cell
Explanation: Signal transduction is known as the transmitting of any signal of a molecule from exterior of cell to interior of cell.This technique is termed as critical is taken care of successful transmission of signal effectively and positive result and reception is done by the cell surface receptors.It is also known as cell signalling. Thus,option(a) is the correct option of all.
