Suppose you want to investigate what kind of material is best for making a warm winter coat. How could you use a freezer, a thermometer, and samples of materials to find an answer?
Answer:
By designing an experiment where the temperature on the thermometer is measured after a chosen (same) time interval when the thermometer is wrapped with the different materials and placed in the freezer
Explanation:
Experimental design
Materials given: freezer, a thermometer, samples of materials
setup:
1. The freezer is put on and made to remain at a particular temperature, mimicking the winter season.
2. Next, different materials for the coat design with equal dimensions are used to rap the thermometer whose initial temperature has been recorded in the same pattern and the thermometer is placed in the freezer and left for a certain time, which is made constant for the different materials.
3. after the time, the final temperature on the thermometer is recorded.
Result interpretation
The temperature is expected to drop after the time in the freezer, but the material with the smaller change (drop) in temperature indicates that it traps more heat hence is the best material for designing a winter coat
independent variables: type of material used
dependent variables: temperature on the thermometer
control variables: time, dimensions of materials, temperature of freezer, pattern of wrapping.

Which statement describes competition within a population?
Several killer whales migrate to a new location.
Two male sea horses fight to win over a female.
Several elk travel together to find and share water.
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.
Thus, the correct option is B.

Describe the net movement of water when a dialysis bag containing a 0.2 M sucrose solution is placed into distilled water, which contains no solutes.
a. There will be no movement of water.
b. Water will move into the bag.
c. Water will move into the beaker.
d. There will be no net movement of water.
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.
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.

Water has a variety of unique properties, including a low melting point, ability to dissolve other substances, and strong adhesion and cohesion. 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.

Answer: 0.5. 1. 2. 3. 5
Explanation:
When the speed of the bottle is 2 m/s, the KE is These are the responses to the speed question: 0.5, 1.125, 2, 3.125 and, 4.5
What does speed mean?Speed is defined as the distance that is allegedly covered in a given amount of time. It is regarded as the speed at which anything is said to move.
In this instance, speed is estimated as 1/2mv2.
As a result, the variables for calculation are:
If the bottle is moving at 2 m/s, then
= ½ (0.250) (2) ^2
= 0.5
If the bottle is moving at 3 m/s,
= ½ (0.250) (3) ^2
=1.125
If the bottle is moving at 4 m/s, then
= ½ (0.250) (4) ^2.
= 2
If the bottle is moving at 5 m/s, then
= ½ (0.250) (5) ^2
= 3.125
= ½ (0.250)(6)^2
=4.5
Therefore, It is regarded as the speed at which anything is said to move.

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.
