Some examples where you have seen a chemical change and the mass has stayed the same

1 answer:

5 0

The law of conservation of mass states that the mass will stay constant given a chemical reaction because no atoms were created or destroyed. This being said, an example can include water evaporating in a clear bottle outside on a hot day ( the mass of the bottle will stay the same, but the liquid water evaporated into gaseous water).

To survive, an organism must be able to maintain stable internal conditions in a changing environment. This process is called ho

Reptile [31]

Answer:

1. Initial air temperature: 0 °C (32 °F)

2. Initial body temperature: 37 °C (99 °F)

3. The expected effect of different factors on body temperature are:

A. Raising air temperature: Increase

B. Lowering air temperature: Decrease

C. Adding clothing: Increase

D. Exercising: Increase

Explanation:

The question is incomplete, it is necessary to look for a software related to this homework.

<u>Homeostasis is a property of organisms that consists in their capacity to maintain a stable internal condition by compensating for changes in their environment</u> through the regulated exchange of matter and energy with the exterior. It is a a dynamic equilibrium controlled by a mechanism of feedback that constitute the self-regulating mechanisms. Examples of homeostasis are temperature regulation and the balance between acidity and alkalinity (pH)

The Human Homeostasis Gizmo™ is a software that allows you to explore how the human body stays at a nearly constant temperature in different conditions. To use it, you have to set the air temperature at 0 °C (32 °F) and the body temperature at 37 °C (99 °F), and click Play. After a simulation of 1 hour, then click Pause and gather the information. Then, do the same cprocedure to test the effect of other factors and Click Reset between each trial. To determine the effect of different factors on body temperature, you have to compare the final body temperature to the final body temperature while there is no specific movement or change.

Then:

1. Initial air temperature: 0 °C (32 °F)

2. Initial body temperature: 37 °C (99 °F)

3. The expected effect of different factors on body temperature are:

A. Raising air temperature: Increase

B. Lowering air temperature: Decrease

C. Adding clothing: Increase

D. Exercising: Increase

This is for a logical reason, anything you do to heat it or generate heat, will increase the temperature. And anything you do to generate cold, will lower the temperature.

The effect of different factors on body temperature according to Gizmo:

A. Raising air temperature: Increase

B. Lowering air temperature: Decrease

C. Click Add to a sweatshirt, hat, pants, and parka. Then, adding clothing:

Maintained

D. Set the Exercise level to 70%, then exercising: Increase

When the temperature increases, it is because you are able to record the results from the software and you see temperature goes from 99 °F to 100 °F. When the temperature decreases. it is because it goes from 99 °F to 97 °F. When it is maintained, there is no change.

Based on the data in Table 1, identify the animal that has the greatest number of sequence differences from the reference animal

Doss [256]

Answer:

( please like and hope it helps)

A) Elephas-2 has 13 sequence differences from the reference animal, and this is the greatest number of animals in the table.

B) From left to right, the order at the tips of the cladogram is: Dugong , Elephas , Loxodonta , Mammathus.

(Loxodonta and Mammuthus can also be reversed)

C) The molecular data, such as that for are widely conserved protein such as cytochrome b , show conserved similarities between organisms such as to dugongs and proboscideans and can be used to support the existence of this relationship.

D) The animals that are related ones had a common assister with certain genetic characteristics. Adaptation to different habitats leads to diversification of morphology but does not change evolutionary relationships.

How does phospholipid structure relate to the selective permeability of the plasma membrane? a critical feature of the plasma me

Katen [24]

The structure of plasma membrane makes it selectively permeable allowing it to regulate the passage of substances into and out of the cell. Small nonpolar molecules can easily across the phospholipid bilayer of plasma membrane because it is hydrophobic. Polar molecules and ion cannot easily across the hydrophobic portion of plasma membrane because it is hydrophilic. Polar molecules and ions usually across the plasma membrane with the help of transport proteins.
