The presence of an epiphyseal plate indicates that epiphesyeal the bone is broken the bone is dead. the bone is increasing in diameter the bone is lengthening the bone is no longer lengthening.
In children and adolescents, new bone growth occurs in the growth plates. They are made of cartilage, a flexible, rubbery material (the nose, for instance, is made of cartilage).
The majority of growth plates are found close to long bones' ends. Bones that are longer than they are wide are known as long bones.
They increase the bone's length and breadth. The growth plates become solid bone as children age. A closed growth plate is one that has entirely solidified into bone. The bones stop growing when a growth plate closes.
Therefore, The presence of an epiphyseal plate indicates that epiphesyeal the bone is broken the bone is dead. the bone is increasing in diameter the bone is lengthening the bone is no longer lengthening.

An epiphyseal plate signifies that the bone is lengthening. When the plate progresses to an epiphyseal line, it indicates that the bone has finished lengthening.
The presence of an epiphyseal plate indicates that the bone is lengthening. The epiphyseal plate is responsible for the longitudinal growth of long bones. Chondrocytes on the epiphyseal side of the epiphyseal plate divide, where one cell remains undifferentiated near the epiphysis, and one cell moves towards the diaphysis. The cells that are pushed from the epiphysis, mature and are destroyed by calcification. This process replaces cartilage with bone on the diaphyseal side of the plate, leading to bone lengthening.
In contrast, the absence or closure of the epiphyseal plate indicates that the bone has stopped growing in length. As a bone matures, the epiphyseal plate progresses to an epiphyseal line, which are the remnants of the epiphyseal plates in a mature bone.

b. by chemosynthesis
c. by photosynthesis
d. They eat other organisms.
(B) The opposite is true, too - when genes from a goat are inserted into a spider's genome, the spider produces goats' milk instead of silk.
(C) The proteins in goats' milk and spiders' silk have the same amino acid sequence
(D)The processes of transcription and translation in the cells of spiders and goats are fundamentally similar.
(E)The processes of transcription and translation in the cells of spiders and goats produce exactly the same proteins anyway.
Answer:
(D)The processes of transcription and translation in the cells of spiders and goats are fundamentally similar.
Explanation:
The genetic information present in the spider DNA can be inserted, transcribed and translated using similar machineries to that present in spiders. This produces the same protein, but the protein is likely processed and exported differently, meaning it plays different roles in each organism.
This is true for lots of scenarios, scientists frequently insert human genes into mice, and even cells in culture!
B. False
Answer:
True
Explanation:
There are four biosafety levels according made to the pathogenicity of the organism. BSL-1 is used for those microbes which do not cause diseases in normal healthy person. BSL-2 is applicable for those microbes which posses moderate risk for humans and against whom therapeutic intervention is normally present in the market.
The worker who uses BSL-2 labs must be trained specifically for handling pathogenic microbes and they should be supervised by competent scientists so that any accident can be avoided. Therefore the statement is true.
