Amoeba are the consumers that surround, engulf, and ingest their food.
<h3><u>Explanation</u>:</h3>
Amoeba is a unicellular organism that belongs to the kingdom Protista. This organism are having eukaryotic cells without any cell walls. These organisms have each and every cellular organelle that are needed to perform metabolism.
Amoeba are consumer in mode of nutrition. Whenever they senses some food, they push a part of their cytoplasm packed in cell membrane towards the food to cover it. This process is called pseupodia.
This pseupodia engulfs the food and performs phagocytosis or pinocytosis. This food is covered in a cell membrane inside the cytoplasm which is called the food vacoule or endosome. This then fuses with a lysosome to digest and then the excretory product is let off by the secondary vacoule.
The important role of the atmosphere is to supply oxygen, water, carbon dioxide and nutrients. It also protects all living things from extreme temperatures and radiation (protects us from harmful solar rays).
False. Probably I don’t have much context
<h3><u>Answer;</u></h3>
Lobules
<h3><u>Explanation;</u></h3>
- In respiratory system the lungs are two spongy, cone shaped organs in the thoracic cavity and are separated from each other by the heart and other structures found in the mediastinum.
- Deep grooves called fissures divide each lung into lobes. Each lobe receives its own secondary bronchus. Each lung lobe is divided into smaller segments that are supplied by a tertiary bronchus.
- <em><u>The segments, in turn are subdivided into small compartments called lobules, which contains, lymphatic vessel, arteriole, venules and also a branch from terminal bronchiole wrapped in elastic connective tissue.</u></em>
Answer:
The correct answer would be -A pre-mRNA becomes mRNA by cutting out different introns
Explanation:
During the process of the RNA splicing, pre-mRNA has several specific segments of sequence that are identified by the spliceosome and then removed from the pre-mRNA. Specific parts that are removed are known as introns and the parts that stuck to become mRNA are exons.
Gene sequences in the eukaryotic genome can code for more than one protein due to removing the different introns every time to become mRNA from pre mRNA.
