How many DNA molecules are present in a sperm cell?
A sperm cell contains 23 chromosomes, each made up of a single DNA molecule. Therefore, a sperm cell typically contains one copy of each chromosome, with a total of 23 DNA molecules.
What sugar does ribonucleic contain?
Ribonucleic acid, or RNA, is a family of biological molecules that is assembled as a chain of nucleotides. Each nucleotide contains a ribose sugar.
What water phenomenon is responsible for the creation of a meniscus?
Water's polarity is responsible for the creation of a meniscus. What happens is that the molecules of water are positively charged on one side and negatively charged on the othe because of the way the individual hydrogen and oxygen atoms bond together. This charged molecule is attracted to the walls of its container, so the water touching the walls of the container curve up to meet the walls instead of lying flat.
Number of sugar molecules in DNA section containing 3 base pairs?
A DNA section containing 3 base pairs would have 6 sugar molecules. Each nucleotide in DNA contains a deoxyribose sugar molecule, so 3 base pairs with 2 nucleotides each would have a total of 6 sugar molecules.
What is contained in each photosynthetic unit of photosystem 1?
Photosystem I contains photosynthetic units with :- 200 or more molecules of chlorophyll a,- small amounts of chlorophyll b- protein saddled carotenoid pigment,-a pair of specialized reaction-center molecules of chlorophyll called P700
How many atoms are in five molecules of hydrogen?
ten as each hydrogen molecules contains two atoms.
Are liquids take the shape of their container?
Yes liquids take the shape of their container. The molecules aren't as close together as in a solid so they can slide over each other.
How many H2O molecules are in a mole of water molecules?
A mole of water (H2O) molecules contains approximately 6.022 x 10^23 molecules. This number is known as Avogadro's number. Each mole of water molecules contains this specific number of molecules due to the atomic/molecular weight and mole concept.
What group contains only molecules that are each assembled from similar organic compounds?
Homologous group.
What do molecules do in a solid liquid and gas?
Solid. The molecules are compacted together and vibrate at high speeds. Liquid. The molecules are still close together but are not fixed and can roll around each other. they spread to take the shape of the container. the molecules move at even higher speeds than solid. Gas. The molecules are far away from each other and move even faster than water Molecules. the spread out or shrink inward to meet the shape of the container.
How does the motion of molecules explain the phases of matter?
Solid: Molecules are tightly packed together into a fixed shape, so the molecules only have room to vibrate in place. ex: a classroom Liquid: Molecules have room to spread out and can slide past each other and takes the shape of the container it's in. ex: a hallway Gas: Molecules have room to go wherever and don't touch each other but still takes form of it's container. ex: outside; parking lot
What happens as the molecules in a liquid move around?
As molecules in a liquid move around, they flow past each other, creating a fluid-like behavior. The molecules continuously collide with each other and with the boundaries of the container, leading to the pressure and viscosity characteristics associated with liquids.
According to the kinetic theory .?
Gases comprise of molecules/atoms that collide with each other and the walls of a container as they are inconstant and random motion. Gas pressure is influenced by the velocity of these atoms/molecules.
What is singly linked list and doubly linked list?
Singly Linked list Each item in the list is called a node and contains two fields  Information field - The information field holds the actual elements in the list  Next address field- The next address field contains the address of the next node in the list. The entire linked list is accessed from an external pointer called the List. Doubly linked list is a collection of node. Each node contains three fields an info field that contains the information stored in the node. The left and right field that contains the address of the node on its left and right. The doubly linked list could be linear, circular and may have a header node.
How do the molecules act in a liquid?
In a liquid, molecules are in constant motion and are loosely packed together. They have enough energy to move past each other but still have some attractive forces keeping them together. This allows liquids to flow and take the shape of their container.
What is a list that contains several levels of items with each level displaying a different numeric alphabetic or bullet symbol?
A nested list is a list that contains several levels of items, with each level displaying a different numeric, alphabetic, or bullet symbol. The different levels of items are typically indented to show hierarchy and organization.
What makes more molecules collide with each other?
Increasing the concentration of the molecules or raising the temperature can both increase the frequency of molecular collisions. Additionally, decreasing the volume of the container can also lead to more collisions between molecules.
