This phylogenic tree is composed based on molecular data (rRNA). What statements can we infer are true about the organisms throu

ghout the tree?
options:

Because the tree is rooted, all branches share a common ancestor.

All organisms have some sort of cellular structure/organization.

All Eukaryotes evolved from Bacteria.

Since the organisms contain RNA, they share the same DNA.

If the organisms contain RNA, the share the same four nitrogen bases.

Answer:

Because the tree is rooted, all branches share a common ancestor.

All organisms have some sort of cellular structure/organization.

If the organisms contain RNA, they share the same four nitrogen bases.

Explanation:

The tree is rooted means that they are sharing common ancestor of all the species which are present in the phylogenetic tree, it shows the evolutionary relationships between the groups of species.

The level of organization is found in an organism that is organized from the small form to the large form such as organelle form cells, cells form tissues, tissues form organs, etc.

If the organisms contain RNA, they share the same four nitrogen bases because RNA contains these 4 nitrogenous bases: Adenine, Cytosine, Uracil, and Guanine.

Although the cause of Parkinson's disease is unknown,research indicates that it may be due to defective nuclei in the cells of t
o-na [289]

Answer:

<u>Nervous System</u> could be studied as a direct result of having defective nuclei and may shed light on the  cause of Parkinson .

Explanation:

<u>PASRKINSON DISEASE -:</u> Parkinson's disease is a progressive nervous system condition. Several regions of the brain are affected by the condition, especially an area called substantia nigra that regulates balance and movement.

A trembling or shaking (tremor) of the limb is often the first sign of Parkinson's disease, particularly when the body is at rest. Typically, on one side of the body, the tremor starts, usually in one hand. The head, legs , feet, and face can also be affected by tremors. Other hallmark symptoms of Parkinson's disease are rigidity or rigidity of the limbs and body, slow movement (bradykinesia) or inability to move (akinesia), and impaired balance and coordination (postural instability).

Emotions and thinking ability (cognition) can also affect Parkinson's disease. Psychiatric disorders such as depression and visual hallucinations are created by some affected persons. There is also an increased risk of developing dementia in people with Parkinson's disease, which is a loss in intellectual functions, including judgment and memory.

Hence , the answer is <u>the nervous system and other regions of brain</u> where the disease has a direct result of having a defective nuclei and may shed light on the cause of Parkinson .

Which forms asks for information about medical conditions such as allergies?
creativ13 [48]
Answer: New Patient Forms or Intake Forms

Explanation:
New patient forms have one purpose: to gather enough information about the patient's habits, general health, medical history, allergies and other information that will enable the medical organization to provide effective and safe treatment for the patient.

Often the forms provide information about the patient's rights and the responsibilities of the medical organization in administering health care to the patient.

Sometimes, new patient forms ask permission to obtain medical data from other medical organizations that had provided medical services to the patient.

jeyben [28]

Question:All known organisms use genetic information to produce protein molecules via the same genetic code. This finding strongly supports the hypothesis that __________.

a) the earliest macromolecules probably arose when lightning struck an oxygen-free atmosphere

b) all organisms are descended from one or a few common ancestors

c) the genetic code readily evolves by natural selection

d) there's only one possible way to encode information in a macromolecule

Answer:

b) all organisms are descended from one or a few common ancestors

Explanation:

Protein synthesis occurs when the nucleotide sequence of the mRNA is read in the form of genetic codes. A specific genetic code specifies the same amino acid in all living beings. For example, the code "UUU" codes for phenylalanine in all the living beings irrespective of their species. This suggests that all the life forms have originated from one or few common ancestors and the genetic code has been preserved during the course of evolution of various species.
