Answer:
Option C, anthrax bacteria
Explanation:
All options i.e amoeba, paramecium and aloe vera plant have eukaryotic cell which have well defined nucleus and layered organelles.
A prokaryotic cell lacks well defined nucleus and also do not have some essential cell organelles. Along with this the cell organelles and nucleus do not have envelope or outer layer.
Only bacteria and archae have prokaryotic cells.
Hence, option C is correct
Sexual production is a means of recreating more of a species. Once there is a gene change whether for the good or bad, and solely if the organism survives to reproduce its gene, then it will be passed on to its children and going further on until there is a large amount of a species with that specific gene. This species evolved. Evolution occurs because of gene changes.
Answer:
B) replaces injured tissues with connective tissue.
Explanation:
Inflammatory response:
When there is injury to the tissues by bacteria, toxins, heat, trauma or by any means then inflammatory response occurs by release of chemicals known as histamine, prostaglandins, bradykinin. It will prevent the spread of injurious agent to nearby tissue. It causes the swelling of tissue by liquid from the vessels. It also disposes of the pathogen and cellular debries and help in the repair of damage tissues.
Answer:
Point mutation
Explanation:
This kind of mutation is the change of one nucleotide in a sequence. The mutation causes a change in the translated amino acid at this position. If the change results in a codon that codes for the same amino acid, then there is no effect. However, a different amino acid may change the properties/characteristics of the translated protein causing some effect on the phenotype of the organism bearing the mutation.
Explanation:
Root hairs are found in the plant it is a hair-like structure present on the surface of the root tip and Root hairs have large surface area that increase the absorption rate of water and minerals.
Water is absorbed by root hair cells through the process called Osmosis and Minerals ions is absorbed root hairs by the process called active transport.
The function of root hair is to collect the minerals and waters present in the soil and then transfer these nutrients and water through roots to different parts of the plant.
