Answer:
To be honest, I would say the best answer is the fact that flies move so you can't be sure if you counted a fruit fly or not. If this is a test i am sorry if you get it wrong, if its homework this is what I would've put.
Answer:
The correct answer is - Yes, the genetic engineer should create a genomic library or a cDNA library.
Explanation:
mRNA isolated from the toxin extracted from the venom gland of the scorpion to create a cDNA library. The cDNA sequence is reverse transcribed by the mRNA that lacks the introns as prokaryotic organisms such as bacteria cannot splice introns.
If the engineer wants to express the toxin in bacteria then he required a cDNA sequence as a genomic clone can not use to clone for making proteins. mRNA should be isolated from the venom gland so it can synthesize cDNA library enriched with toxin protein sequence.
Explanation:
well a mutation in my opinion is genetic change that happened in the animal this could be beneficial or may not be. natural selection is a process that ensures only the best of the species survives and more of them will produce because all of the flawed ones will die off. adaptaion is when a plant or animal adapts to its surrounding over time they may develop a charterisric that will help them thrive. all of them tie togethor
Answer:
Severage water is most desasterous thing of urbun areas.
noise pollution also damage species
Explanation:
severage water contaminates rivers,canals and other water reserviours that can be harmfull for fish comunity moreover animal may drink water from that water bodies that causes problems in them.
contaminated water from industries also effects water bodies.
noise pollution disturb mental life of man as well as animals .
Answer:
The correct answer is - Anaphase.
Explanation:
Cell division can be either mitosis or meiosis. Mitosis cell division has these phases:
A. Interphase - non-dividing phase with to G1, S and G2 sub phase. In this genetic material doubles and cell size increases.
B. Prophase- chromosomes shorten and condense by coiling. Centrioles move in opposite directions.
C. Metaphase - spindle fibres bind to kinetochores and pulls it the chromosomes on the equator of the spindle forms a plate called the metaphase plate.
D. Anaphase- these get condense and centromeres split into two and the spindle fibres pull the daughter centromeres to opposite poles.
E. Telophase is the last phase of Mitosis.
