You are sitting by a lake. You drop a leaf on the lake and notice that it floats on the top of the water. Which of the following properties of water could help explain what you observed?
Answer:
Issuen Shingeki... Messatsu!
Explanation:
What you've just witnessed is something called "Buoyant force".
Buoyancy is the upthrust in the particles between the Atoms of the leaf and the water. They have the opposite charge, allowing them to repel each other- Ultimately allowing the leaf to float.
Or simply, the leaf is lighter and is less dense.
Answer:
a.
Explanation:
It has a strong tension.

In a well-structured paragraph, evaluate the experimental design of the investigation into the osmolarity of different types of apples for adequate controls and measurement techniques .
Answer:
To determine the osmolarity of two types of apples in this experiment they use four sucrose solutions and twenty-four apple cylinders. They let these cylinders stand overnight in separate beakers of sucrose solutions, and repeat the procedure for the second variety. For the first variety, they record the temperature for the sucrose solution and remove the core to determine their combined mass. Then they will record the final masses and calculate percent change by using the percentage change in mass formula. After, they repeat these same steps for the second variety.

Asexual Reproduction occurs when there is only one parent that gives rise to an offspring which has the identical genetic makeup of the parent. It occurs in most single celled organisms such as bacteria and some multicellular organisms such as fungi and some plants. Some advantages of asexual reproduction are it is fast and efficient. It does not require a male and a female. Organisms can reproduce quickly! A disadvantage is that there is no genetic diversity and it can only be done by simple organisms.
Sexual Reproduction involves the combining of genetic information from two parents to produce a new organism that is a combination of both parents. It occurs in most complex organisms. Some advantages to sexual reproduction are that it creates genetic diversity. It allows for evolution of the species. A disadvantage is that it requires two organisms to reproduce, a male and a female. It also requires more energy than asexual reproduction.
Using the table below, list at least two advantages and disadvantages of Asexual and Sexual Reproduction.

Which were likely the closest ancestors to early animals?
a Mosses
b Cyanobacteria
C Colonial protists
d Algae
Answer:
Algae i believe
Explanation:
I say this because the earliest animal is comb jelly
Most likely the closest ancestors to early animals are colonial protists. This is because they are eukaryotic, multicellular organisms that have mitochondria.
What do you mean by Ancestors?Ancestors may be defined as an early type of animal or plant from which others have evolved.
Due to living in groups, they are known as Colonial protists. The most primitive organisms are cyanobacteria which are single-celled organisms.
Therefore, most likely the closest ancestors to early animals are colonial protists.

Does respiration expend more energy than photosynthesis?
Answer:
Explanation:
Photosynthesis vs Cellular Respiration Photosynthesis and cellular respiration are two basic metabolic processes occurring in the energy conversion of ecosystems. During photosynthesis, carbon dioxide and water are used in the synthesis of organic compounds with the aid of sunlight. This organic compounds can be used by cells as food. During cellular respiration, energy in the form of ATP is produced by breaking down food. The main difference between photosynthesis and cellular respiration is that photosynthesis is an anabolic process, where the synthesis of organic compounds occurs, storing energy whereas cellular respiration is a catabolic process, where the stored organic compounds are utilized, producing energy.

Which of the following organelles are found in plant cells? Select all that apply.
A: cell wall
B: nucleus
C: central vacuole
D: flagella
E: lysosomes
Answer:
cell wall, central vacuole, and nucleus
Explanation:
The organelles that are found in plant cells are the cell wall, nucleus, and central vacuole. The correct options are A, B, and C.
What is a plant cell?Plants cells are the cells present in plants. These cells are the same as the animal cell, but they contain a cell wall and the animal cell does not contain a cell wall.
Plants cells also contain vacuole which is filled with water, that is missing from the animal cells. They are eukaryotic cells and these cells also contain a nucleus that is the brain of the cell.
The cell wall is made up of cellulose, filaments, and pectin protein. It gives the plant cell rigidity and protection. The vacuole is filled with water.
Thus, the correct options are A, cell wall, B, nucleus, and C, central vacuole.

D) a system
A structure that performs a specialized function within a cell is known as is system.
What is system?Humans and other sophisticated multicellular organisms have coordinated organ systems that perform the functions necessary to sustain life.
The body is organized at many stages that progress together. Organ systems are made up of tissues, which in turn are made up of tissues and organs.
The coordinated activity of an organ system's organs determines how well it functions. In sophisticated multicellular animals like people, the cells are arranged into tissues, which are collections of comparable cells that collaborate on a particular activity. Organ systems are collections of organs with connected.
