Answer:
b
Explanation:
The correct answer would be that water will move into the bag.
The 0.2 M sucrose solution in the dialysis bad has a lesser water potential when compared to the distilled water that has no solutes. By law, water moves from the region of higher water potential to the region of lower water potential. The dialysis bag will, hence, act as a semi-permeable membrane and allow water into the bad from the surrounding distilled water.
The correct option is b.

Answer:
The answer is false!
Explanation:
I took the K12 science quiz. I hope this helps! Have a blessed day! :)
The statement "An aquarium with a glass lid is an example of an isolated system" is false as light, air, and heat can transfer through the glass lid.
What is an aquarium?An aquarium is an artificial place that is made for putting fish and other water animals in houses buildings and other places. Aquariums are made up of glass so can we, so we can see the fish's aquarium also have oxygen pumps the water also changed in the aquarium from time to time and. The aquarium is kind of decorative.
Aquariums are made up of glass, and they are open from the top so that fish can get air.
An aquarium is not an isolated system as light year and heat can transfer through the top and fishes are living organisms that need an open system to breathe and live.
Therefore, the statement is false.

The knee ________.
a. is completely enclosed by a strong articular capsule
b. is a multiaxial joint
c. has ligaments present inside as well as surrounding the articular capsule
d. is the simplest joint in the body
Answer:
The correct answer is: C) has ligaments present inside as well as surrounding the articular capsule.
Explanation:
The knee joint is a hinge (ginglymus) type synovial joint that is formed by three different bones: the femur, the tibia, and the patella.
Given the nature of the hinge joint, it should only allow flexion and extension, but it also grants a small degree of internal and external rotation. For this reason, the knee joint cannot be considered a multiaxial joint, since it only fully moves in one axis and slightly moves in a second one (this is why most people consider the knee joint a uniaxial joint, but some others say it is actually a biaxial one).
The knee joint isn't completely enclosed by a strong articular capsule. The knee joint is rather thin and it contains the patella, menisci, bursae, and ligaments of the knee.
The knee is not the simplest joint in the body. It is formed by three bones and there's also the menisci, which are fibrocartilaginous structures that help increase the stability of the joint and act as shock absorbers as well.
The knee does have ligaments both inside and outside the articular capsule. The intracapsular ligaments are two cruciate ligaments (one anterior and one posterior), which hold the tibia in place; the transverse ligament that connects both menisci; and the posterior and anterior meniscofemoral ligaments. The extracapsular ligaments are the patellar ligaments (connects the patella to the tibia), the two collateral ligaments (medial and fibular, one on each side of the knee, connecting the femur to the tibia and to the fibula, respectively), and the anterolateral ligament.

Which distribution pattern in species can be considered the most easily measurable
Answer:
local endemics
Explanation:
The most common distribution pattern in species can be considered by their geographical distribution, as different species get distributed as per their climate and the different regions that suit them the most.
What is the significance of the geographical distribution?It is significant because they differ in different parts of the world and provide suitable climatic and other environmental conditions for various animals, plants, and microorganisms to live and evolve. Its significance can be seen in the difference between the life forms in the temperate area and those in the Antarctic area.
Hence, the most common distribution pattern in species can be considered by their geographical distribution, as different species get distributed as per their climate and the different regions that suit them the most.

Explanation:
In the Colorado mountains, three species of bumble bees live in the same habitat. Each species has a different proboscis length: short, medium, or long. Each visits nectar-producing plants that match its proboscis length. This situation suggests that natural selection in the three bumble bee species has resulted in
Answer:
resource partitioning
Explanation:
Resource partitioning can be defined as the division of limited resources that enables species to avoid competition when they live in the same habitat. Moreover, interspecific competition is defined as the competition for limited resources among individuals of different species. In a given environment, species can be competing for essentially the same limiting resources. In the case of the bumblebees, the competence is reflected by differences based on the length of the proboscis (competence for the food), thereby resource partitioning enables species to coexist with one another.

Different kinds of garden plants take in water from the soil.
Answer:
I think its B if I'm wrong I'm sorry
Two male sea horses fight to win over a female describes the competition within a population. So, the correct option is B.
What is Competition?Competition is defined as an interaction between organisms or species in which both require a resource in limited supply that reduces the fitness of both organisms because the presence of one of the organisms always consumes the available resource which reduces the quantity.
Competition is defined as the fight between different organisms by limited resources. Some examples of interspecific competition between lions and leopards that vie for the same prey and interspecific competition between rice fields with weeds growing in the field, two male seahorses fighting to win over a female.

Which statement is MOST useful for explaining the unique properties of water? A. Water molecules are nonpolar, so a very minimal electrical force attracts them to one another. B. Water molecules may sometimes gain or lose an oxygen atom to become ions, which are held together by ionic bonds. C. Water molecules are held together by hydrogen bonds, which are attractive forces stronger than ionic bonds. D. Water molecules are held together by hydrogen bonds, which are attractive forces weaker than covalent bonds.
Answer:
D. Water molecules are held together by hydrogen bonds, which are attractive forces weaker than covalent bonds
Explanation:
Water is a chemical molecule with unique properties such as a low melting point, ability to dissolve other substances, and strong adhesion and cohesion, as stated in this question. This unique properties can be attributed to the HYDROGEN BONDING that holds the molecules of water together.
However, the hydrogen bonding of water molecules is an attractive force that is quite WEAKER than ionic or covalent bonds but it holds water molecules tightly to one another.

Victor has been studying the vascular systems of plants. He wanted to find out if food coloring would travel up the stalk of celery faster if the temperature of the water increased. Victor set up his experiment with three cups of colored water at different temperatures, three equal sized celery stalks, and a stopwatch. Cup A was filled with colored water at 21 C. Cup B was filled with cold colored water at 4 C, and Cup C was filled with warm colored water at 30 C. One celery stalk was placed in each cup at the same time. Victor timed how long it took the colored water to travel to the leaves at the top of the celery stalk. He measured the time in minutes. What is the independent variable
Answer:
temperature
Explanation:
The independent variable would be the colored water at different temperatures.
The independent variables are changeable or controllable variables supplied directly by researchers in the course of experiments. They produce effects on the dependent variable and are thus referred to as the 'cause' variable. The dependent variables are referred to as the 'effect' variables because their values vary based on that of the independent variables.
In this case, the only controlled variable of all the variables supplied by Victor is the temperature of the colored water. Changing the temperature of the colored water is expected to have effects on the time it will take for the colored water to travel to up the stalk of celery. Hence, the temperature is considered as the independent variable while the time it takes for the colored water to travel to the leave would be the dependent variable.
