What materials? There are none provided.
First figure out what ALL of these have in common.
It would probably be the ability to fly since they can all fly.
Then you would pick something that only 4 out of the 5 share.
For that, you can separate the pelican because it's big, unlike the rest.
It starts at the bottom, so the pelican would be all the way at the bottom
Add that characteristic before the name of the animal and keep on making your way up until only 1 of the birds has a characteristic that the other ones don't have
Answer:
Polymers.
Explanation:
Carbohydrates are known as the important part of human diet, and they present in fruits, grains, and vegetables. Through the glucose known as simple sugar a component of starch it provides energy to the body.
The small sub units of glucose which connects together, and form a molecule is known as monomers (single unit), and a group of monomers joints together and form large molecules are known as polymers (many units).
Answer:
D. Sequence of nucleotides in the DNA of the cell.
Explanation:
Proteins are a type of biomolecules in living systems responsible for many phenotypic characteristics in organisms. Proteins are synthesized by a process called gene expression, which encompasses transcription and translation.
Using the central dogma of biology to trace, DNA (genes) contains information that encodes the production of proteins in the body. Therefore, the sequence of nucleotide bases in the DNA of a cell determines the sequence of mRNA that will be produced during transcription and ultimately, determines the specific type of proteins (amino acid chain) that will be produced in a cell during translation.
Answer:
There are three anatomical barriers in our immune system skin, the mucous membranes, and bony encasements.
The skin, consist of dermis or epidermis layer that provide conditions which are not favorable to bacterial growth. Normal biota present in skin inhibits potentially harmful microbes. Sweat glands and hair follicles produces toxic lipids and lysozyme that can kill bacteria. Symptoms rise due to skin barrier is redness, itching and allergy.
Mucous membranes are present in the lining of body cavities such as the genitourinary tract, the gastrointestinal tract and respiratory tract. These membranes are made up of epithelial cell and secerets mucus that traps microbes and avoid their entry into the body tissues. Mucus also contains lysozyme that is responsible for degrading bacterial peptidoglycan. Symptoms rise due to mucous membrane are coughing, sneezing and sour throat.
Bony encasements are present in skull and rib cage that avoid direct contact of organs from injury and entry of microbes.
