The correct answer is I, II and III.
A phagocytic cell of a vertebrate organism is a critical component of the immune system. Its main action is to engulf and ingest foreign and possibly harmful particles, bacteria and dead or dying cells.
There are many different types of phagocytes and some of these include the macrophages, the neutrophils, and the dendritic cells.
The macrophages are phagocytic cells which can exit the bloodstream and detect pathogens outside the circulatory system.
Neutrophils contain toxic granules which can kill pathogens only by contact. Dendritic cells are located in the parts of the body which can easily be infected and can act as messengers who warn the body of threats. They do so by sending antigens as messages.
Yes jaguars And black panthers compete for the same resources because the are booth carnivores living in the same area trying to survive. So yes the two species are in competition.
Complete question: While taking a walk in a park, Muskaan observed an insect on a pitcher plant (Nepenthes). Immediately the flower opened up and the insect slid down. To which of the following categories does the pitcher plant belongs?
a) Saprophytes
b) Insectivorous
c) Parasite
d) Symbiotic
Answer:
The correct answer is option b. Insectivorous
Explanation:
A carnivorous or insectivorous plant is the one that obtains most of its nutritional necessities from the capture and consumption of protozoans or animals, especially insects and arthropods.
These insectivorous plants grow in poorly nutritional soil, so they need to get nutrients from their prey. These species attract and trap their prey, and by the action of specific enzymes and digestive bacterias, they can absorb the insects' nutrients.
These insectivorous plants make use of their flowers to trap the prey. These tramp flowers are cup-shaped, and at the bottom of this cup, there is a liquid where insects get trapped and die.
Insects are attracted by aromas produced by the edges of the trap and when they land, they slip and fall inside, and once drowned, the enzymes digest them.
Answer:
The statement true of all proteins, carbohydrates and fats is that human body is able to synthesize them all.
The statement unique to proteins is that proteins are made up of instructions according to DNA.
Explanation:
Carbohydrates, Proteins and fats are macronutrients and required by body in larger amounts. All these macromolecules are made up of building blocks like proteins are from amino acids, carbohydrates from monosaccharides and fats from triglycerides. Human body can also synthesize these macronutrients. Like proteins can be synthesized by central dogma. Glucose can be synthesized by gluconeogenesis from glycogen and fats can be synthesized from acetyl-CoA and NADPH.
The proteins are made up by a process known as central dogma. The first step of central dogma is replication in which a replicated copy of DNA is produced in a cell. The second step is transcription for the production of messenger RNA from DNA. At last mRNA is used for the production of proteins on ribosomes.
