Answer:hydrogen atomic no and mass no is 1. In hydrogen there is one electron ,one proton and zero neutron.
Explanation:
Neutron is zero because neutron
Nnumber =atomic no - mass no so 1-1=0.
Answer: D) The lizard and the snake are secondary consumers.
Explanation:
Producers are organisms that, simply put, produce their own food. All photosynthesizing plants are considered to be producers. Animals cannot be producers.
Primary consumers eat producers.
Secondary consumers eat primary consumers.
Tertiary consumers eat secondary consumers, and so on.
The lizard eats a fly, which is a primary consumer. This makes the lizard a secondary consumer.
The snake eats a mouse, which is a primary consumer. This makes the snake a secondary consumer.
A) is incorrect because the hawk is a tertiary consumer.
B) is incorrect because grass is a producer, not a consumer
C) is incorrect because the lizard is a secondary consumer
No. Medical progress is allowing us to progress and evolve in different ways. That is the only difference. Having medical progress and good medical care allows us to pursue different types of activites we wouldn't be able to pursue otherwise. This at the same time brings a different type of evolution.
Answer:
a. transcription/RNA processing
: pre-mRNA, snRNA
b. translation
: mRNA, rRNA,
c. not used in protein synthesis: RNA primers
Explanation:
pre-mRNA, mRNA, rRNA, RNA primers, snRNA
a. transcription/RNA processing
: pre-mRNA, snRNA
b. translation
: mRNA, rRNA,
c. not used in protein synthesis: RNA primers
The pre mRNA the product after transcription from the DNA is processed eg by addition of poly A tail, splicing etc before undergoing the process of translation, the snRNA also help in performing this function. In translation, the mRNA is trnslated to proteiin in the ribosomes which is also made up of rRNA and proteins. RNA primers is not needed in any of these two, only i DNA replication as the DNA polymerase is uable to begin the synthesis of adding nucleotides to a DNA strand.
