When water freezes into ice the hydrogen bonds formed allow them to be spaced farther apart, making them take more space and the overall density decreases, so ice float in the water.
What is density ?The density of can be referred as the mass per unit volume which means the ratio between mass and volume, where how much stuff an object has in a unit volume.
It is a measurement of matter, where it mainly presents the mechanism of matter is bind together, put forwarded by the Greek scientist Archimedes
Density = Mass/Volume

Move the terms into the correct empty boxes to complete the concept map describing the four types of macromolecules
The four main categories of biological macromolecules are carbohydrates, lipids, proteins, and nucleic acids.
Each is a vital part of the cell and carries out a variety of tasks. These molecules make up most of a cell's mass when they are all combined.
They play a crucial role in the cell and carry out key tasks. Proteins are necessary for immunity, growth, and maintenance, and they also serve as enzymes, hormones, and other things. The primary source of energy is carbohydrates.Macromolecules, for instance, offer structural support, serve as a reservoir for stored energy, have the capacity to store and retrieve genetic information, and can speed up biological operations.Proteins, carbohydrates, nucleic acids, and lipids are the four main categories of macromolecules that perform these crucial roles in a cell's life.Stores and transmits information are nucleic acids.

In the early 1900s Alfred Wegener proposed the continents were “drifting.” The scientific community did not support his theory due to a lack of scientific evidence. Using what you just heard, would you support Wegener’s hypothesis or not?
Answer - The main reason that Wegener's hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth's spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true.
Answer:
No, I would not.
Explanation:
I would not support his theory, due to the lack of information, and he had no good conclusion on why or how they were drifting

Q2 so when Einstein sayed a time is but a stubborn illusion i dont understand if its right or no
beacuse how time is a illusion when we can feel it passing like you wake up at the morning at night the sun fall that mean the time is real you can feel it moving like a hand of a clock
so the time is not a illusion
THESE AL Q ARE MADE BY ! MY MIND IS EXPLODING
Answer:
Q1. A black hole absorbs energy from the light of the star. That's all
Q2. Time is an illusion because it's a fourth dimension we can not be able to see, at least at this present. You can not feel the time, because it is not tangible and you only feel the illusion that you could feel the time, which is not.

Termites are insects that live in colonies. In a colony, the king and a queen are responsible for reproduction. Workers spend most of their time caring for the other termites and building the nest. Soldiers protect the nest from attacks.
The organization of the termite colony is an example of which benefit of social behavior?
The organization of the termite colony is an example of the benefit of the social behavior which is referred to as division of labor.
What is Division of labor?This involves the separation of work into different units in which each unit is done by separate people. In this scenario, everyone has a task and is done so as to achieve success or a common objective.
In the termite colony, every group have their functions such as the workers spending most of their time caring for the other termites and building the nest and the soldiers protecting the nest from attacks.
This helps to ensure that there is adequate running of the colony with minimal issues which is why division of labor was chosen as the correct choice.

Which correctly distinguishes between how a pine tree and an apple tree reproduce?
Answer:
Pine seeds develop in the bracts of the female pine cone and are not surrounded by fruit. The apple seed grows in the ovary of the apple flower and is surrounded by a fleshy wall that grows into the fruit.
Explanation:
How does the pine tree reproduce?
Male pine cones produce pollen, which is like a powder. The male cones release their pollen, which is carried around the air by blowing wind, and hopefully to another female pine cone on a different pine tree. If the pollen reaches a female pine cone, this process is called pollination
How does an apple tree reproduce?
Flowering plants --including the apple tree--reproduce by transferring pollen from the male organ or stamen of one blossom to the female organ or pistil of another. Some flowering plants require no pollinating partner--the flowers are sel- fertilizing.

Some of the reasons of for the sudden development of cell theory after a long break are:
Advancement in technology and technological innovations.More manifestation of greater scientists More co-operation of scientists.As at the time Robert Hooke and Anton Van Leeuwenhoek made their discoveries about cell, both of them and other scientists of that time do not have access to great sophisticated instrument which could aid their research. Their inability to have access to technological innovations do not make them go far.
It is not surprising that Theodor Schwann, Mathias Schleiden and Rudolf Von Virchow made their breakthrough within a short period of time simply because of the use of improvement of technological innovations with which they use to invent the cell theory.

How does Claire's diagnosis explain why 1 mL of liquid from her small intestine digested
protein slowly but 1 mg of her pure protease digested protein normally?
Type your answer here
According to Claire's diagnostic, her small intestine either lacks or just has a very little number of proteolytic enzymes. Proteins in the body or on the skin are broken down by proteolytic enzymes.
What is protein digested into by protease?Any of a set of enzymes that divide proteins into shorter pieces (peptides), and subsequently into their constituent amino acids, is known as a proteolytic enzyme. It is also known as a proteinase, protease, or peptidase.
Protease is yet another crucial enzyme for the effective breakdown of meals. Proline dipeptides from gluten and casein, as well as proteins and polypeptides from plants and animals, are all primarily broken down by it.
Proteins are broken down into amino acids by protease. Lipids, which are fats and oils, are broken down by the enzyme lipase into glycerol and fatty acids.

What molecules' purpose is to be a bond site for the monomers in these macromolecules? Macromolecules-Carbohydrates, lipids, proteins, and nucleic acids.
The molecules' purpose to bind monomers in biomolecules (carbohydrates, lipids, proteins, and nucleic acids) is to form polymers by linking subunits.
What are biopolymers?Biopolymers such as carbohydrates, or proteins can be defined as linear chains of minor molecules such as, in these cases, monosaccharides and amino acids, respectively. These biopolymers are linked by specific bonds (including glycosidic or peptide bonds) to form linear chains of subunits.

Pretend you are looking through a microscope at cells from different human organs. In which organs would you expect to find cells with the most mitochondria? The most lysosomes? The most ribosomes? Explain your answers.
Answer:
Muscle cells need a lot of energy to expand and contract, so they have a large number of mitochondria, which burn glucose for energy.
Lysosomes are responsible for holding and releasing enzymes to break down many different molecules for many different purposes. One of the major functions of the liver is metabolizing nutrients and toxins the body ingests, which is done using enzymes. So liver cells would have the most lysosomes compared to other organs.
Ribosomes are a key part in protein synthesis, which every cell does. Though, the liver is responsible for most of the protein production for the body, so liver cells would have the most.
mitochondria function as subsystems within the larger system of the cells as a whole which explains why a mitochondria shown on the right is know as the power house of a cell?
Answer:
The proteins synthesized by the proteins in mitochondria are utilized to generate adenosine triphosphate (ATP) from the food. This ATP acts as the energy currency of the cell, because of which the whole cell and body get energy. Thus, mitochondria are called the powerhouse of the cells.
