Answer:
anticodontRNAs
Explanation:
bring their amino acids to the mRNA in a specific order. This order is determined by the attraction between a codon, a sequence of three nucleotides on the mRNA, and a complementary nucleotide triplet on the tRNA, called an anticodon. This anticodon also specifies the particular amino acid that the tRNA carries.
El hipotálamo produce la hormona liberadora de corticotropina CRH que estimula la glándula pituitaria para secretar la hormona adrenocorticotropina ACTH.
hope this helps :)
The answer is d.
Meiosis is a kind of cell division that produces daughter cells that are genetically different to parent cells and contains half number of chromosomes comparing to parent cells.
At the beginning, the parent cell duplicates its chromosomes just like mitosis. The cell divides and leads to 2 genetically identical daughter cells.
This is where mitosis ends. But in meiosis, the 2 cells produced divides again, but without duplicating it's chromosomes. Therefore, this leads to 4 daughter cells at the end, each with halved number of chromosomes.
When a cell has a halved number of chromosomes, it's said to be haploid.
This is usually common in gametes so that biodiversity can be achieved.
Therefore, the answer to this is d.
The level of organization the student observed is community.
There are different levels of organization in Biology, more specifically Ecology, and these levels are listed below and explained in order from the highest to the lowest level.
The biosphere, which includes the largest part of the Earth, represents all living organisms on the land, in the ocean, and in the atmosphere.
An ecosystem is the next level of organization, which is a specific area with living organisms. It includes all the living organisms in that area but also the non-living environmental aspects, so it includes both biotic and abiotic factors.
A community includes all biotic factors of a specific area, so it is the biotic part of an ecosystem. This means that a community refers to all the populations of different species that live in a specific ecosystem and interact with each other.
A population is a level below a community, and above species, which refers to all of the individual organisms of one species that live in a specific community and interact with each other.
A species is a group of organisms that live in the same area, and interact with each other to breed, to produce viable offspring. All members of a species are genetically related and can be bred to produce fertile offspring.
Since the student in the example is observing a lake, which is an ecosystem, and he listed all the living organisms he found in that lake, we can conclude that the level of organization observed in the table is community. He described different shrimp species, and an insect species, and he didn't describe any abiotic factors, so that brings us to the level of community.
Answer:
Pancreas.
Explanation:
Pancreas is an organ that acts as both exocrine as well as endocrine gland. As exocrine gland, it secretes digestive enzymes into the small intestine that help in digestion of complex food molecules.
As an endocrine gland, it secretes glucagon (from alpha cells) and insulin (from beta cells) hormones, directly into the bloodstream. Both of these hormones are responsible for the regulation of blood sugar level in the body.
Thus, the correct answer is 'pancreas.'
