Answer:

1. It serves as the functional unit of the nervous system. <em>b. neurons</em>

2. It collects information from the sense organ such as the eyes and the nose. <em>c. peripheral nervous  system</em>

3. It serves as the primary organ of the  central nervous system. f. spinal cord​  

4. It controls or regulates the body's internal brain environment, including the body temperature,  pulse and respiration rate, and bood pressure. <em>e. autonomic nervous  system</em>

5. It is one of the systems that is directly involved in maintaining the normal functions of cells. <em>d. nervous system</em>  

Explanation:

Neuron: Neurons are the structural and functional units in the nervous system.  Neurons transmit nervous impulses. These cells are formed in general by a cellular body, dendrites that are cytoplasmic extensions that receive stimuli from other cells, and an axon that is a long formation capable of conducting the electrochemical signals. Every neuron forms connections with other neurons. These connections are known as synapsis.

Peripheral nervous  system: Sense information is received by the peripheral nervous system and processed by neurons and synapses in the central nervous system. There are three types of neurons involved in this transmission: sensory or efferent neurons, interneurons, and motor or efferent neurons.

Spinal cord: The nervous system might be divided into the central nervous system and peripheral nervous system. There are two organs involved in the central nervous system that funtion as control centers. One of them is the brain, and the other organ is the spinal cord, surrounded by the vertebral column.  

Autonomic nervous  system: The autonomic nervous system is conformed by the sympathetic nervous system and the parasympathetic nervous system. It has too many functions in the organisms, controlling pressure, heart bitting, body temperature, sexual responses, urination, digestion, general metabolism, among others. It controls and regulates the whole organism.  

The nervous system: Homeostasis refers to stability, balance, or equilibrium. The organism needs to maintain homeostasis to guarantee the correct functioning of cells, tissues, organs, and so on. The homeostatic regulation is controlled by the endocrine system and by the nervous system, which acts as the control center.

The two main stages involved in protein synthesis that is in central dogma theory are transcription and translation. The process of transcription and translation occurs in the nucleus and ribosome respectively. In the translation process, DNA is used as a template and mRNA is synthesized. In translation, a protein is synthesized by translating the codon.

Further Explanation:

The double-helical structure of DNA is duplicated through a process called DNA replication. Then, the DNA undergoes a process of transcription and form RNA. After this, RNA processing starts with post-translation modification and forms three different types of RNA molecules that are rRNA, tRNA, and mRNA. Transcription mainly occurs in the nucleus of the cell. In this stage, DNA acts as a template and synthesized new mRNA. Then, the formation of protein occurs. After the process of transcription, mRNA goes into the ribosome to synthesize new protein. In TRANSLATION processes, mRNA is converted to protein. Transfer ribonucleic acid is a kind of RNA that helps in decoding a messenger RNA sequence into a specific protein.

In TRANSLATION processes, mRNA is converted to protein, but to translate mRNA, it goes under many processing before into protein mainly in eukaryotes.

  • 5’Capping: In capping 7, ’methylguanosine is added to the 5’end of the transcription result by joining 5’to 5’phosphate.Capping is done only to protect the nascent mRNA from degradation and help in initiating translation.
  • 3’poly A tail: Around 100-250 residue of adenine nucleotide added to the 3’end of mRNA to maintain the stability of mRNA. Firstly, the 3’end of mRNA is cleaved and makes free 3’OH. Poly-A tail help in transporting the mRNA from the nucleus to cytoplasm for the translation process.

If the pride is taken over by new individuals, what happens to the females? males? cubs?.
Nookie1986 [14]

The cubs are a significant barrier to reproduction when a new male coalition first takes control of a pride. Mothers of surviving cubs won't mate again until their young are at least 18 months old, but if their cubs are lost, they will mate right away.

  • Following that, males leave on their own or are driven out by other men who take control of their pride. It is common for a new male to kill all the cubs when he joins the pride in order to pass his genes on to all future cubs. The major function of males in the pride is defending the pride's territory.
  • Female lionesses will devour the cubs of other pride, but not the cubs of their own pride. The "egalitarianism" of female lions stands in stark contrast to the autocratic behavior of wolves, wild dogs, and several other species, where dominant females prevent subordinates from reproducing.
  • When a female lion gives birth, she leaves the pride and doesn't come back until the cubs are several weeks old. After that, the adult females band together to take care of and protect the young.
