A segment of a DNA molecule has the base sequence ATGAAC. Write a shorthand structure for this segment and for its complementary strand, using the symbols D for deoxyribose and P for phosphate.
Answer: See attached picture.
Explanation:
DNA or deoxyribonucleic acid is the name for the molecule that contains the genetic information in all living things. This molecule consists of two strands that wind around each other to form a double helix structure.
The basic unit of nucleic acids are called nucleotides, which are organic molecules formed by the covalent bonding of a nucleoside (a pentose which is a type of sugar and a nitrogenous base) and a phosphate group. So each nucleotide is made up of a pentose sugar called deoxyribose, a nitrogenous base which can be adenine (A), thymine (T), cytosine (C) or guanine (G) and a phosphate group.
What distinguishes one polynucleotide from another is the nitrogenous base, and thus the sequence of DNA is specified by naming only the sequence of its bases. The sequential arrangement of these four bases along the chain is what encodes the genetic information, following the following criterion of complementarity: A-T and G-C. So the sequence of these bases along the chain is what encodes the instructions for forming proteins and RNA molecules. In living organisms, DNA occurs as a double strand of nucleotides, in which the two strands are linked together by connections called hydrogen bridges.
The chemical convention of naming the carbon atoms in the pentose nucleotide pentose numerically confers the names 5' end and 3' end ("five prime end" and "three prime end" respectively). The 5'-end designates the end of a DNA strand that coincides with the phosphate group of the fifth carbon of the respective terminal deoxyribose. A phosphate group attached to the 5'-end allows the ligation of two nucleotides; for example, the covalent bonding of the 5'-phosphate group to the 3'-hydroxyl group of another nucleotide, to form a phosphodiester bond.

Which of the following statements about scientific theories is incorrect? a.Theories are suggestions made by curious people, b.theories can change if new evidence arises, c. Theories are used to explain why natural phenomena occur, d. theories are bases on sets of hypotheses
Answer:
d. theories are bases on sets of hypotheses
A scientific theory is a theory based on suggestions. It can change with the new evidences. Theories explain natural phenomenon. Thus, correct option is D.
What is a Scientific theory?A scientific theory is a model which explains the facts on the basis of observations and experimentation. A scientific theory can be proved by methods involving procedures, measurements, observations and evaluation of results. Scientific theory validates all the facts of nature and summarizes patterns found in nature.
Scientific theories are testable this means that new evidence should be compatible with a theory. If it is not then the theory is refined or rejected. A theory needs to be substantiated, explanatory, predictive, and testable.
A scientific theory is an explanation of some aspect based on a body of facts that have been repeatedly confirmed by observation and experiment.
Therefore, the correct option is D.

A. True
B. False
Answer: Hi there I think That I can help You!!!
The cell membrane contains a phospholipid bilayer, but the terms are not interchangeable. Part of the cell membrane is a phospholipid bilayer, made of two layers of phospholipid molecules. However, the cell membrane also contains other macromolecules like membrane proteins, and carbohydrates.
Explanation: So the correct answer is TRUE! don't forget to ate 5 stars and give brainlist!
The statement "the cell membrane consists of one layer of phospholipids" is absolutely false.
What is a Cell membrane?A Cell membrane may be defined as a type of biological membrane that significantly separates the interior components of the cells from the external environment. It also provides protection to the cell as well as other cell organelles.
A cell membrane is made up of a phospholipid bilayer. This illustrates that the two layers of phospholipid molecules are utilized in order to make an effective cell membrane.
It acts as selectively permeable in nature. The head or polar region of phospholipid is hydrophilic while the non-polar tail is hydrophobic in nature.
Therefore, the statement "the cell membrane consists of one layer of phospholipids" is absolutely false.

Although bipedalism is unusual, humans are not the only living bipeds. For example, some flightless birds are also bipedal. Identify a living nonprimate animal that is also a biped. Then, compare its bipedalism to our biped-alism.
Answer:
Explanation:
Human and birds as the basis for comparison. Some birds walk and run with their backs and femurs tilting at small angles to the horizontal and with bent knees while most human walk uprightly with legs straight and this can be seen in the duty and task performed by man.
Humans exert on the ground while walking two-peaked pattern of force which makes some human work very fast but Birds do not exact two-peaked pattern of force.
Human walking for individual with same body mass is relatively economical of metabolic energy while Bipedal locomotion is economical for wading birds, it is expensive for geese and penguins.

Read the following scenarios carefully and explain how natural selection will occur in each.
Some worms eat at night (meaning they are nocturnal) and some worms eat during the day (meaning they are diurnal). Most birds eat only during the day, so they are only eating diurnal worms, due to the fact that the nocturnal worms are burrowing during this time. Each spring when the worms reproduce, about 500 offspring are born but only 100 of them live long enough to reproduce themselves.
Answer:
The correct answer is - Noctural worms have the advantage over diurnal due to the fact that the nocturnal worms are burrowing during the feeding time of birds.
Explanation:
Natural selection is the process in which organisms adapt according to environmental changes to increase their survival rate. Natural selection leads to natural changes in different organisms.
In this case, diurnal worms are forced by the natural selection here to adapt to the change if they want to survive. Here, natural selection works for the nocturnal and against the diurnal.
Generally, coral reefs are found in shallow waters between ______ degrees N latitude and ______ degrees S latitude.
Answer:
30 degrees;
30 degrees
Explanation:
Coral reefs are formed when the skeleton of the corals merge and combine with each other. The formation of coral reefs takes many years . Corals are the organism living in the ocean. They live in dense colonies and clusters. Coral reefs provides an ecosystem for other marine organisms to live in. The species live in the coral reefs and maintain their population. Corals live in the region of the ocean that has warm water and between the latitudes of 30 degrees North and 30 degrees South.

What is the adenosine triphosphate or ATP molecule?Adenosine triphosphate or ATP is a high energy molecule used by the cell to carry out different types of chemical reactions because this molecule releases energy that is coupled to the generation of other reactions.
The adenosine triphosphate or ATP molecule is produced mainly during the process of cellular respiration in an aerobic organism which requires the presence of oxygen. Moreover, anabolism occurs when polymers break down into monomers. while catabolism occurs when polymers are synthesized from monomers.
Therefore, with this data, we can see that the adenosine triphosphate or ATP is the energy coin of the cell which is mainly generated during a series of metabolic reactions called cellular respiration in organisms such as humans.

Cardiogenic shock shock results when: The body loses an excessive amount of blood The body's blood vessels are dilated The left ventricle cannot pump enough blood to meet the body's demands Trauma results in temporary loss of the autonomic function of the spinal cord
Answer:
The left ventricle cannot pump enough blood to meet the body's demands
Explanation:
Cardiogenic shock is a problem that occurs when the heart cannot pump the adequate amount of blood to supply all organs. In this situation, the left ventricle, responsible for pumping oxygen-rich blood, cannot pump enough blood to tend the body's demands. This causes blood pressure to drop and oxygen in the tissues to be lacking. In addition, this situation can cause accumulation of fluid in the lungs. This is a very dangerous problem, being one of the main causes of myocardial infarction.
