How does water behave when it freezes?

Answers

Answer 1

Answer:

During freezing, water molecules lose energy and do not vibrate or move around as vigorously. This allows more stable hydrogen-bonds to form between water molecules, as there is less energy to break the bonds...Thus water expands as it freezes, and ice floats atop water.

How do active and passive transport help a cell respond to changes in the environment?

Answers

- both transport things across the cell membrane
- help the membrane maintain homeostasis

Active and passive transport help a cell in responding to the changes in the outside environment as both of these processes help in transporting substance into and out of the cell and maintaining the homeostasis in cell.

What is Cellular transport?

Cellular transport is the process of transportation of substances into and out of the cell. Cellular transport includes different processes such as active and passive transport. The active transport requires energy for transporting substances against the concentration gradient and the passive transport does not require energy as the substances move in the direction from high concentration to low concentration of solutes.

The transport of substances which are required by the cell and excretion is possible through active and passive transport. these processes helps in maintaining homeostasis in the cell.

Explanation:

The main change in skull anatomy that occurred from the dawn horse to the modern horse is that the skull of the modern horse is dramatically larger.

What are the characteristics of the dawn horse?

Eohippus, (genus Hyracotherium), also called dawn horse, an extinct group of mammals that were the first known horses. They flourished in North America and Europe during the early  Eocene (56-33.9 million years ago).

Eohippus, "dawn horse" or more correctly called Hyracotherium, which lived in the Eocene approximately 55-58 million years ago, is the oldest ancestor of the modern horse.

Hyracotherium, or eohippus (dawn horse), as  scientists called it, first appeared on earth as a small, shy creature no bigger than a dog. It existed between 55 and 5 million years ago.

The small intestine exchanges nutrients to help maintain homeostasis. Through the process of digestion, food is broken down into smaller pieces. Sugar is a molecule that supplies our cells with energy. Sugar is a large molecule and is transported through carrier proteins. Sugar molecules are often transported into the bloodstream even when the concentration of glucose is higher in the bloodstream than in the intestine. Based on this scenario, is the transport of glucose accomplished through osmosis, diffusion, or active transport?

Answers

Answer:

Diffusion

Explanation:

The sugar is spreading to various places within the body and is trying to make one place less concentrated.

Based on the given scenario,the transport of glucose is  accomplished through diffusion.

What is diffusion?

Diffusion is defined as the process of movement of molecules which takes place under concentration gradient. It helps in movement of substances in and out from the cell.The molecules move from lower concentration region to a higher concentration region till the concentration becomes equal.

There are 2 main types of diffusion:

1) simple diffusion-process in which substances move through a semi-permeable membrane without the aid of transport proteins.

2) facilitated diffusion- It is a passive movement of molecules across cell membrane from higher concentration region to lower concentration.

There are 2 types of facilitated diffusion one is osmosis and dialysis.

A famous celebrity has an extreme security system for their estate. The security system includes sensors in the ground as well as on the sides of the buildings. A loud truck drives down the road entering the estate. There is a sensor in the ground and another on the side of the security guard’s shed. If both sensors are 100m from the truck, which sensor will pick up the noise of the truck first and why?

A.
Guard Shed - The sensor on the security guard’s shed will detect the sound first because the sound is traveling through the air and sound will travel fastest through a gas.

B.
Ground - The sensor in the ground will detect the sound first because the sound is traveling through the dirt and sound will travel fastest through a solid.

C.
Same time - Because the sound is traveling through both the ground and the air at the same time, it will reach both the shed and the ground sensor at the same time.

D.
Neither sensor - 100m is too far for the sound to travel. Neither sensor will pick up the sound of the truck until it is closer to them.

Answers

Answer:

B. Ground - The sensor in the ground will detect the sound first because the sound is traveling through the dirt and sound will travel fastest through a solid.

Explanation:

Sound wave is an example of mechanical wave, which means sound waves require a medium to travel through. However, how fast a sound travels is dependent on the kind of medium it travels through. Sound travels fastest via a SOLID medium, then liquid and slowest through gases.

According to this question, sensor in the ground and side of the security guard’s shed were placed in an estate owned by a famous celebrity. A loud truck, then, drives down the road entering the estate.

Based on the principles of sound eaves movement, the sound from the truck will be picked by the sensors in the GROUND first because the sound is traveling through the dirt and sound will travel fastest through a solid.

Explanation:

From the scenario described the Engineers have met one of the main criteria which is for it to be durable. A design needs to be made with a material that is available, durable, and cheap in order for it to be as efficient as possible while also selling and being profitable. By finding the material polycarbonate they have made sure that the design will be durable as well as cost-efficient since the material is "not too costly". Now if they are able to acquire the material in large quantities then they would have met the availability criteria as well.

Answer:

Violating 'Ceteris Paribus' {Other factors constant} assumption, as both food & space are varied (simultaneously)

Explanation:

Weight Growth is the dependent (effected) variable in this case. And, independent (causal) variables are food amount are living space respectively.

However particular independent factor's (food or living space) impact on dependent variable ie weight growth : can be determined only by - examining individual variable (food or living space) impact on weight growth. So, either of the two variables should be varied, & not both should be varied simultaneously.

This would imply depiction of each factor's clearer individual impact on the dependent factor.
