Ants and bee's don't have a backbone, instead, in most cases, they have an exoskeleton.
Hope this helped:)
The code for this procedure allows for imaging a patient twice.
A pulmonary perfusion imaging or pulmonary ventilation scan is used to check that how well air and blood are able to flow through your lungs. Pulmonary embolism is a condition in which two or more arteries are blocked by the blood clot in lungs and it is the fatal complication after the trauma.
Answer:
Chromosome number variation: B. Down syndrome
Loss-of-function allele : D. PKU
Physiological trait
: E. Lactose metabolism
Discovery-based science
: A. Human Genome Project
Genetic cross: C. Model organism
Explanation:
Down syndrome is a condition in which there is an extra copy of the chromosome number 21. Hence, it is a chromosome number variation.
Physiological traits refers to any function of a body. Hence, it matches with lactose metabolism.
Human Genome Project was a project under which the whole genome of the humans were sequenced. Hence, it is a discovery based science.
A genetic cross is made between model organisms to test for the offsprings that would be produced from a cross. Hence, genetic cross and model organism math with each other.
Answer:
A tendon
Explanation:
Tendon is a fibrous connective tissue which attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to attach the bone to muscle
²²⁷₉₀ Th is the daughter nucleus (nuclide) produced when ac227 undergoes beta decay by emitting an electron.
A fast energetic electron or positron called a beta particle is released from an atomic nucleus during beta decay, which changes the original nuclide into an isobar of that nuclide. When a nucleus has too many protons or neutrons, beta decay happens when one of the protons or neutrons is converted into the other. A neutron decays into a proton, an electron, and an antineutrino in beta minus decay: n p + e - +.
During beta decay, an unstable nucleus undergoes the conversion of a neutron into a proton, so
¹₀ n ----> ₁¹p + ₋₁⁰e ( Z + 1 )
The complete reaction is as follows:
²²⁷₈₉AC -----> ²²⁷₉₀ Th + ₋₁⁰e
Therefore, the daughter nucleus is ²²⁷₉₀ Th.
