Answer:
Hydrogen bonds
Explanation:
Hydrogen bonds exist between the two strands and form between a base, from one strand and a base from the second strand in complementary pairing. These hydrogen bonds are individually weak but collectively quite strong.

Which of the following is an example of a glacial formation?
glacial horn
mesa
stack
alcove
Answer:
i think glacial horn is an example of a glacial formation?
Glacial Horn is a pointed peak like feature which are bounded on at least three sides by glaciers. Thus, glacial horn is a best example of glacial formation. Hence, option A is correct.
What is Glacier?
Glacier is a slow moving mass of ice observed in the high mountain valleys and colder Polar Regions.
Every mass of ice are not glacier, it must be at least six hundreds of a square mile in size and the thickness will be more than 164 feet.
The principal components for the formation of glacier is snow.
Hence it is observed during winter in the regions where a lot of snow fall occurs and less snow will melt in summer.
Glacial horn are specifically have flat faces which show a pyramidal shape and sharp distinct edges like a pointed peak structure.
Hence, option A is correct.

Answer:
How it got there. Anyone's hair can be carried and blown from anywhere, if so you'd have to go through every persons dna that had contact with a victim and contact with the contactie and so on and so on.
"The chicken genome has about 17,000 genes, and the grape has about 30,000 genes." Which claim about human genes would be most strongly supported by this statement? A. The number of human genes is not especially large compared to other organisms. B. Humans have many more genes than other species. C. Humans are genetically very similar to other species and differ by only a few key genes. D. Humans are genetically very different from other species and share few if any genes with them.
Answer:A
Explanation: I took the quiz.
The claim about human genes would be most strongly supported by this statement is, that the number of human genes is not especially large compared to other organisms.
What do you mean by Genes?Genes may be defined as a stretch of DNA that helps in the determination of each characteristic specifically.
According to the human genome project, humans have 20,000-25,000 genes. while the tiny eater flea Daphnia has the most genes of any animal which is 31,000.
Therefore, the claim about human genes would be most strongly supported by this statement is, that the number of human genes is not especially large compared to other organisms.

Briefly describe the role of the ribosome and tRNA in translating the mRNA sequence into an
amino acid chain.
Answer:
Explanation:
Messenger RNA (mRNA) is translated into protein by the joint action of transfer RNA (tRNA) and the ribosome, which is composed of numerous proteins and two major ribosomal RNA (rRNA) molecules. ... Transfer RNA (tRNA) is the key to deciphering the code words in mRNA. The ribosome brings together the mRNA to be translated and a set of molecules called transfer RNAs, or tRNAs, which are floating in the cell. ... Each tRNA is designed to carry a specific amino acid that it can add to a polypeptide chain. tRNAs bring their amino acids to the mRNA in a specific order.

When an action potential is generated within a motor neuron, ________. When an action potential is generated within a motor neuron, ________. all of the muscle cells within the motor unit are stimulated to relax the muscle cells from a neighboring motor unit will contract every muscle cell of the motor unit is stimulated to contract only select muscle cells within the motor unit are stimulated to contract the muscle cells of the motor unit will occasionally contract
Answer:
every muscle cell of the motor unit is stimulated to contract.
Explanation:
Stimulus in biology can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ. Therefore, the senses are necessary for behavior because stimuli must be sensed in order to respond.
Stimulus control can be defined as a phenomenon that arises when a living organism responds or behaves in the presence of a stimulus and in another way in the absence of a stimulus.
For example, opening the door of a microwave oven as soon as its timer beeps.
Example II; When your body touches a hot object, you quickly move away and feel some pain subsequently.
Action potentials generates the nerve impulse in a motor neuron.
When an action potential is generated within a motor neuron, every muscle cell of the motor unit is stimulated to contract.

O skin and anus
O large intestine and small intestine
O liver and kidney
O tubules and ureters
Answer:
Its A skin and anus
(just did test)
Explanation:
The skin and the Anus are sites where waste products are released from the body but not where they are produced.
Which process of the human body eliminates the waste products?Excretion is the biological process through which any unwanted or waste products are eliminated from the body.
Large and small intestines produce waste products that are not completely digested by the stomach. The liver and kidney are also the sites of waste products like the removal of carbon dioxide and synthesis of urine respectively.
Therefore, the skin and the Anus are sites where waste products are released from the body but not where they are produced.

How was life today similar and different to the Silurian period? ( animals, plants , organisms)
Answer:
The creatures developed in silurian period have evolved to live in sea bottoms.
Explanation:
Silurian life that is marine benthic which are bottom lying organisms belongs to the community of ecological zones that express themselves. As the gradients of temperature, pressure, and salinity. Consists of a community that is adapted to live in a darker region, used to lie in quieter environments that are in deep offshore water. These are much like the reef communities today as they do not tolerate excessive sediments. Prefer wave water that is shallow than 30 meters. These platforms are very gentle and are found over a hundred km gradients. Most of the fish represent the Silurian age and are widely distributed in marine environments. Examples of jawless fish, terrestrial fungi etc.
