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

Answers

Answer 1
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).

Explain how the sense of smell works on a molecular level. Be sure to describe what is happening in the brain as well?

Answers

Answer:

The smell is one of the senses that is created by the small molecules that are released by the food, aromatic substance, or any substance into the air. When we inhale during the breathing process these small molecules enter our nose and trap in tiny hair of the nose.

These molecules dissolves in mucus present in the nose to reach the specialized receptor cells known as olfactory receptor neurons. These neurons detect the smells and send the information directly to the brain to the olfactory bulbs that work to detect the smell.

Which mechanism best explains these facts?
O founder's effect
Ogene mutation
Onatural selection

Answers

Answer:

O founder's effect

Explanation:

A founder effect can be defined as the loss of genetic variation when a new population is established from a few individuals. This process is known to increase the frequency of particular gene variants (alleles) at different loci when they are selectively neutral (or nearly neutral), and thereby such genes are fixed by genetic drift (i.e., through the random sampling of founder individuals). Interestingly, it has been discovered that the majority of South American and Central American Indians are nearly exclusively in the O blood group, which has been further associated with random genetic drift and a founder effect.

Which of these is the most likely prediction that the meteorologist would make about the weather? There is a possibility of

precipitation
hurricane
tornado
fair weather

Answers

Answer:

D. Final answer.

Explanation:

The study of a living being is called biology

The correct answer is D.

The barometer is a device is used to measure the pressure in the atmosphere. The information helps to check the water precipitation in the atmosphere by which they can predict the weather.

According to the question, the two barometers are showing a range between 950 -1000mmhg.

These indicate the fair weather

Hence, the correct option is D that is fair weather.

The must be eroded into sediment.
ebo...
The rock must melt in the Earth's interior.

Answers

Answer:

The rock must be eroded into sediment

Explanation:

In order to form sedimentary rock, the accumulated sediment must become compacted and cemented together.

For any type of rock to become sedimentary rock, the rocks must first be eroded into sediment. Thus, the correct option is C.

What are the sedimentary rocks?

Sedimentary rocks are the types of rock which are formed by the accumulation or deposition of different minerals or organic particles at the Earth's surface, followed by cementation. Sedimentation include all the processes that cause these particles to settle in place.

Clastic sedimentary rocks form from the accumulation and lithification of the mechanical weathering debris on the Earth's surface. Examples of sedimentary rocks include breccia, conglomerate, sandstone, siltstone, and shale.

Therefore, the correct option is C.

If plant gene alterations cause the plants to be deficient in photorespiration, what would most probably occur

Answers

Answer:

This question lacks options, options are:A) Photosynthetic efficiency would be reduced at low light intensities.

B) Cells would carry on the Calvin cycle at a much slower rate.

C) There would be more light-induced damage to the cells.

D) Less oxygen would be produced.The correct answer is  C

Explanation:

Photorespiration is a complex process that takes place in the mesophyll of plant leaves, when there is light and a high concentration of O2. In this process, the chloroplast, peroxisome, mitochondrion and cytosol interfere, which is responsible for this process is an enzyme called rubisco (ribulose-1-5-bisphosphate carboxylase / oxygenase). This enzyme fixes carbon during the photosynthesis phase, but when the temperature increases, its behavior changes, becoming an oxygenase, that is, it stops absorbing carbon and begins to capture oxygen.To protect themselves from photooxidation, the photorespiration process occurs in plants, preventing light from damaging the molecules involved in photosynthesis, that is, by means of photorespiration, plants prevent the over-reduction of the photosynthetic electron transport chain and photoinhibition, especially under stress conditions, then acts as an alternative sink for energy or reducing power.
