Answer:a nearly automatic machine installation for milking cows
Answer: B) Histidine- glycine - glycine - tyrosine - glycine.
Explanation: Amino acids are coded for by three nucleotide sequence found in an mRNA molecule. These three nucleotide sequences are known as codons. Every amino acid is coded for by at least one codon. Some amino acids are coded for by more than one codon. The phenomenon by which more than one codon codes for a particular amino acid is known as degeneracy. The codons are said to be degenerate.
From the information provided, CAU codes for histidine, GGU, GGC and GGG code for glycine while UAC codes for tyrosine.
Answer:
THE ANSWER BELOW and i really hope this is the answer your looking for if not i am sorry
Explanation:
A. Brain - Organ level
B. Neurons - Cellular level
C. Neurotransmitters - Chemical level
D. Neurons and neuroglial cells - Tissue level
E . Brain combined with the spinal cord and spinal nerves - Organ System level
There are five levels of organisation of life; cell, tissue, organ, system and organism.
The smallest unit is cell. Neurons are nerve cells.
Aggregation of cells forms a tissue. Neurons and neuroglial cells aggregate to form nervous tissues and are hence at tissue level.
Aggregation of tissues forms an organ. Brain is an example of organ. It is formed from aggregation of nervous tissues.
Tissues aggregate to form organs while aggregation of organs constitute a system. The nervous system consist of brain combined with spinal cord and spinal nerves.
The nervous system release chemicals called neurotransmitters.
Answer:
Ionic Bond
Explanation:
Ionic bonds form when a nonmetal and a metal exchange electrons, while covalent bonds form when electrons are shared between two nonmetals. An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions.
Answer:
This plant is probably most closely related to ferns (Option B).
Explanation:
Ferns belong to the pteridophyte group. Pteridophytes characterizes for having a sporophyte that has stems with leaves and a root. It also has primitive xylem composed by tracheids and phloem, both of them formed by vascular bundles located in a central cylinder.
Spores are its dispersion units and are responsible for colonizing new areas. They also constitute the resistance units under extremely unfavorable conditions.
Their life cycle is composed of the asexual phase (sporophytic phase) and the sexual phase (gametophytic).
The sporophyte, the dominant generation, is perennial. Its aerial part might disappear during unfavorable seasons, but it reappears during spring or summer.
The gametophyte, instead, is ephemeral and must be in the water for its survival, and for sexual reproduction to be successful. In the presence of water, masculine gametophyte -antherozoids- are released and they swim to the archegonium to meet the ovocell. Antherozoids can swim because they have flagella. After fertilization, a new sporophyte is produced.
