Answer:
Translocation
Explanation:
Translocation is a chromosomal defect in which part of a chromosome breaks off and reattaches backward on the same chromosome.
Translocation can happen due to many reasons like:
A) Some of the changes that arise around the time of conception or production of sperm or egg.
B) The inheritance of altered chromosome from father or mother.
Translocations can be divided into two forms:
- Reciprocal translocation
- Robertsonian translocation.
In reciprocal translocations, fragments of two chromosomes break off from two different places, break and swap each other's segments. While in Robertsonian translocation one chromosome attached with other.
Hope it help!
Dehydration synthesis :) it means that monomers (like glucose or lactose) when bonded together release water molecules
Answer:
the petrified log looks like the original tree.
Explanation:
A tree to be petrified first needs to be buried. An element laying on the surface can not be petrified because it is exposed to many different factors (such as<em> organisms, microorganisms, climatic conditions</em>, etc.), that affect the petrification process. So, in the case of a fallen tree, first, it needs to be covered by many sedimentary layers. Once it is underground, it also needs the presence of underground water and minerals. Water replaces the original organic material with minerals (silica, calcite, and pyrite). This replacement process results in the conversion of the woody material into a fossil of the original material. Very often, the tree details are so preserved that the fossil looks exactly like the original trunk.
Depending on the preservation degree, a fossil can be useful for different studies about the past.
Answer:
Patient-oriented: performed on humans with direct contact between the patient and the investigator.
Disease-oriented: identify molecules and cells linked to a disease.
Explanation:
Clinical research is a study conducted on humans, design to develop techniques and create knowledge. It involves several activities orientated to test a hypothesis and draw conclusions about diseases.
Patient-oriented clinical research is a specific type of clinical study with humans, that requires an <u>interaction between the patient and the investigato</u>r. This research is performed to detect, treat and prevent human diseases as well as understand the disease's mechanism to develop technologies and create knowledge in this field. For example creating a less invasive technique to treat a patient, heart assist devices, vaccines, inhaled medicine for pulmonary problems and cellular therapies.
Disease-oriented clinical research is a study that seeks to understand <u>molecular or cellular features that are linked to human diseases</u> to identify their response to treatment. For example identify cancer target molecules, use of genes and proteins for the diagnosis and treatment of cardiovascular diseases, stem cells to treat autoimmune diseases and genetic therapies to treat molecular and cellular problems.
Answer:
Bacteria isn't made by random selection. Random pooling can be the factor.
Explanation:
DNA is important to the domain bacteria.
