Heat from the sun makes it through near the Antarctic (where the hole is) is melting the ice and not allowing some key species to feed. seals don't have ice to come up for air through like normal so polar bears starve. loss of land means less food for a lot of species because the hunting grounds is closing and there is no room to expand.
Answer:
<u>Attributes of E. coli articulation frameworks </u>
Advantages:
-
Quick articulation
-
Simplicity of culture
-
Significant returns
-
Cheap
-
Genome alterations conceivable
-
Large scale manufacturing quick and practical
Disadvantages:
- Proteins with disulfide bonds hard to communicate
- Produce unglycosylated proteins
- Proteins created with endotoxins
- Acetic acid derivation development bringing about cell lethality
- Proteins created as consideration bodies
- produce dormant proteins
- needs collapsing
<u>YEAST SYSTEM </u>
Advantages:
- Nearness of post translational change
- discharge can be recognized by emission signal
- develop in minimal effort media
- straightforward hereditary control
Disadvantages:
<u>Bacillus articulation frameworks </u>
Advantages:
- Solid discharge
- no association of intracellular consideration bodies
- Simplicity of control
- Hereditarily all around portrayed frameworks
- Exceptionally created change and quality substitution advancements.
- Unrivaled development qualities
- financially savvy recuperation
<u>Animal Cells:</u>
Advantage:
- nearness of post interpretation adjustment
Disadvatages
Issues with creature utilization
Can get sullied with creature diseases
Exorbitant downstream preparing
Answer:
The correct answer is- Histone
Explanation:
DNA is approximately 2.2 m long thread which has to be adjusted in a microscopic nucleus so DNA must be in a supercoiled form to be present in the nucleus and this supercoiling of DNA is done on histone protein.
Histone protein is a positively charged protein that is made up of eight proteins so it is called histone octamer. Each histone has 2 copies of each protein that is H2A, H2B, H3, and H4.
DNA is negatively charged and histone protein is positively charged therefore DNA wraps around histone protein which causes the packaging of DNA. So the correct answer is histone protein.
The answer is D. Species A will have fewer phenotypes.
Alleles are alternative forms of a gene. In species A, the leaf color is controlled by two alleles, for example, P and Q. They will have three possible genotypes - PP, PQ, and QQ. Three different genotypes give maximum three phenotypes.In species B, leaf color is controlled by three alleles, for example, L, M, and N. They will have six different genotypes - LL, LM, LN, MM, MN, and NN. Six different genotypes give maximum 6 phenotypes.
Answer:
Al Capone, Fred "Killer" Burke, and Bugsy Moran.
Explanation:
Augustus "Smiling Gus" Winkler was a big-time gangster who had his fingerprints surgically altered so as not to be identifiable through fingerprint technology. He was part of Eagan's Rats gang and would participate in some of the most notorious crimes such as the St. Valentines Massacre in 1929.
When he moved up north, he met up with some of the world's famous gangsters like Al Capone, Roger Touhy, Fred Burke, and Bugsy Moran. But in 1933, to secure himself, he turned evidence against his friends and accomplices. But he was not to be safe for long, for he was gunned down by unknown assailants rumored to be ordered by Frank Nitti on October 9, 1933.
