The type of RNA that delivers amino acids to the ribosome during protein synthesis is tRNA.a) trueb) false
DENIUS [597]

Answer:

A). True

Explanation:

tRNA, which means transfer RNA is one of the three types of RNA known in nature. The tRNA is found in the ribosome, where it plays a pivotal role in protein synthesis (translation). Transfer RNA is the RNA responsible for reading the nucleotides in the mRNA codon and carrying the amino acid that corresponds those codons to the ribosome.

The tRNA has a 3-dimensional structure that allows it to carry anticodon that reads codon and also carry amino acids on opposite ends. Hence, according to this question, tRNA is a type of RNA that delivers amino acids to the ribosome during protein synthesis.

The cell membrane is made up of a double layer called dna bilayer
GrogVix [38]

Answer:

The cell membrane is composed mainly of phospholipids, which consist of fatty acids and alcohol. The phospholipids in the cell membrane are arranged in two layers, called a phospholipid bilayer.

Mitochondria, the organelles involved in cellular respiration, can also generate chemicals called reactive oxygen species (ROSs)
ch4aika [34]

<u>Answer:</u>

Mitochondria, the organelles involved in cellular respiration, can also generate chemicals called reactive oxygen species (ROSs). ROSs can damage mitochondria. Damaged mitochondria generate more ROSs than healthy mitochondria. This is an example of a positive feedback mechanism

The reactive oxygen species that are given out by the mitochondria during cellular respiration are the major cause of aging. Though this has a lot of negative effects but this also has a small amount of positive effects such as the start of angiogenesis or cell proliferation.

Choose which tissue would line the uterine (fallopian) tubes and function as a "conveyor belt" to help move a fertilized egg tow
olchik [2.2K]
The ciliated simple columnar epithelium is a tissue that would line the uterine tubes and function as a conveyor belt to help move a fertilized egg toward the uterus. The ciliated columnar epithelium transfers mucus and constituents through cilia and is originate in the upper respiratory area the fallopian tubes, the uterus, and principal part of the spinal cord. It is the main objective of contamination for common cold illnesses.

The organisms that harness non-biological energy and convert it to biologically relevant/useful energy are called __ 1 __ _. The
mamaluj [8]

Answer:

The organisms that harness non-biological energy and convert it to biologically relevant/useful energy are called __<u>autotrophos or producers</u>_. The organisms that consume these are called _<u>herbivores</u>_ (it should end in -ores) which occur at the __<u>second</u>_ trophic level. The number of trophic levels that any ecological system will primarily dependent on the _<u>consumer</u>_ organisms.

Explanation:

 In the trophic web occurs energy transference through organisms occupying different levels in the chain. Each level feeds on the preceding one and becomes food for the next one. The first link is occupied by autotroph organisms, which are the producer. The following links are the consumers: herbivores are primary consumers and feed on producers. Carnivores are secondary consumers and feed on herbivores, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.  

Every link has an effect on the superior links and the immediately anterior link, meaning that whenever one of the links changes, the other ones will be affected.  

Autotrophs or producers synthesize inorganic substances, such as light, and turn them into organic matter according to their own needs. These organisms are photoautotrophs, such as plants, or chemoautotrophs. They occur at the first trophic level.

Heterotrophs are those incapable of producing their own organic matter, so they feed on producers, depending on them to get proteins and energy. In the trophic chain, heterotrophic organisms occupy the first, second, or third consumer level, after producers. These animals can be herbivorous, carnivorous,  omnivorous, hematophagous, ichthyophagous, and etcetera. All of them depend on autotrophic organisms.

In the particular case of herbivores, they occur at the second throphic level feeding on producers and being eaten by carnivores.

In general, most trophic chains are composed of 4 or 5 levels, depending on the number of consumers present, and the energy transference between levels.
