Answer:
a) vertebra
Explanation:
A laminectomy is a surgical procedure performed to remove the lamina, a vertebral bone, in order to ease pressure on the spinal cord that causes back pain, numbness on the legs and even problems to control bladder or bowel movements.

reptile
bird
mammal
Ifan animal's heart has three chambers and it lays amniotic eggs, it should be a reptile(e.g. pythons and monitor lizards). However, through amniotic egg, a protectiveadaptive sac inside the egg, it os useful for reptiles, amphibians, birds andmammals.
Answer: C. Turning food scraps into compost for plants.
Explanation:
A renewable resource is the one which can be resued once used. On earth the renewable resources are abundantly available like sunlight, water, and air. Recycling of renewable resource can be define as the reuse of resource or conversion of resource into another form so that it can be used again.
A food trash can be coverted into a compost which can be a valuable recycling product useful for the growth of the plants.
Answer;
C. Biomes
Savanna is considered a transitional biome because it is intermediate between two biomes.
Explanation;
Savanna biome is a transitional biome between those dominated by forests and those dominated by grasses. It is characterized by an extensive cover grasses with scattered trees.
Normally savanna biomes are associated with climates having seasonal precipitation accompanied with a seasonal drought.
Answer:
c - biomes

Answer:
It means the way genes are expressed is the same in most organisms.
Explanation:
All living organisms use the same DNA or RNA as their genetic material. The manner in which the information in these genes are encoded or expressed is known as the GENETIC CODE. Genetic code comprises of all the codons that specifies amino acids in all living organisms. Only 20 amino acids in different sequential pattern makes up all proteins.
Nearly all living organisms use the same genetic code, as a codon does not specify a different amino acid in another organism. It is universal in all organisms that AUG codon specifies Methionine. Only slight differences to this pattern of genetic expression has been discovered, hence, the genetic code is said to be NEARLY UNIVERSAL.
The idea of a nearly universal genetic code refers to the common genetic 'language' shared by nearly all organisms. This means that, across an extraordinarily diverse array of species, the same sequences of DNA and RNA (the genetic code) translate to the same amino acids, which, in turn, build the same proteins. The universality of this code strongly suggests that all life shares a common origin.
The nearly universal genetic code refers to the fact that virtually all living organisms use the same codons, or sequences of DNA and RNA, to code for specific amino acids, which are the building blocks of proteins. This conservation of codons is seen across a vast array of species, with minor exceptions. For instance, if the mRNA encoding the globin protein in horses is transferred to a tulip cell, the tulip would synthesize the same protein, suggesting a common origin of all life on Earth.
The 64 possible combinations of triplet codons coding for 20 amino acids and with the occurrence of only one genetic code demonstrates the idea of degeneracy in the genetic code. This means that more than one codon can specify the same amino acid. For instance, unusual amino acids such as selenocysteine and pyrrolysine have been found in archaea and bacteria, which use unique codons.
Ultimately, the universality and degeneracy of the genetic code highlight the homologous characteristic shared by all species suggesting they share a common ancestor. This is powerful evidence for the shared biochemistry in all forms of life.

The cardiovascular system is also known as the circulatory system.
It is made up of the heart, the blood vessels namely arteries, veins and capillaries, and approximately five liters of blood.
The circulatory system's major functions are to transport oxygen, hormones, and nutrients to every cell in the body, and to tale away cellular waste products from the cells such as carbon dioxide and bring them to excretory organs where they are expelled out of the body.
The circulatory system is kept running by the heart, which is a muscular organ the size of the closed fist of an adult. It pumps about 5 liters of blood every minute throughout the body.
The cardiovascular system is also known as the circulatory system. It delivers oxygen and nutrients to tissues and helps regulate body temperature.
