Which of the following is a true statement? Physical property change is always better than chemical property change.
o Physical and chemical propery change can happen at the same time.
Chemical property change is better than physical property change.​

Answers

Answer 1

Answer:

the second one

Explanation:

Sometimes it can be tricky to know whether or not a chemical reaction has occurred. For example, when you melt ice into water, you can write the process in terms of a chemical reaction. However, the chemical formula on both sides of the reaction is the same. Since the chemical identity of the matter in question is unchanged, this process represents a physical change.

Thus melting point is a physical property. On the other hand, flammability is a chemical property of matter because the only way to know how readily a substance ignites is to burn it. In the chemical reaction for combustion, the reactants and products are different.

none are better, depending on for what

His study of the experimental method

Answers

Answer: The study of plant varieties.

Explanation:

This question relates to the studies that Gregor Mendel, founder of modern genetics, performed at the University of Vienna.

Experimenting on pea plants, Gregor Mendel was able to establish a lot of the rules of heredity that we know today even though his research was not fully appreciated or understood during his own life.

He credited the study of plant varieties to have been most crucial to his final analysis because farmers had been crossbreeding varieties for millennia to bring about better traits in plants.

Water located in wells underground is ground water. Therefore, the correct option is option C.

Water that is found below the earth's surface in cracks in rocks and the crevices between soil particles is known as groundwater. It is essential for maintaining ecosystems on our planet and supporting human activities. Groundwater is created and made available by precipitation and surface water that seeps into the ground. It gathers in subterranean aquifers, which are enormous water reservoirs contained in permeable rocks or sediments. The thickness and depth of these aquifers vary. Groundwater supply is influenced by elements like rainfall, geology, and human use. Groundwater is an important resource since it is necessary for a variety of purposes. It provides over half of the world's population with their main supply of drinking water.

Therefore, the correct option is option C.

Answer:

The structure and function of cellular proteins and how they interact to contribute to traits.

Explanation:

Proteomics is a research area that studies proteomes and their interactions with other cellular components (e.g., transcription factors involved in DNA-protein interactions, ribonucleoprotein complexes involved in RNA-protein interactions, etc). A proteome can be defined as the entire set of proteins synthesized by an organism. The proteomics field allowed us to identify common protein functions (structural and enzymatic functions), as well as understand how protein expression (which is regulated by genetic and environmental factors) influences cellular metabolic activities (e.g., iron uptake).

3. If muscle contraction were an athletic game, calcium would be the most valuable player. Describe,
using some depth, the roles calcium is serving both inside the muscle fiber and outside at the NMJ.

Answers

Answer:

Explanation:

At the NMJ, calcium is responsible for "unlocking" the ligand gated channels, allowing AcH to be released into the synaptic cleft. When AcH binds and the AP moves down the sarcolemma and into the t-tubule, calcium is then released from the sarcoplasmic reticulum into the sarcoplasm. It then binds to the calcium subunit of troponin, causing a confirmational change in tropomyosin, exposing the active sites on actin. This allows the myosin heads to bind, causing muscle contraction.

How does a single fertilized egg cell develop into all the different cells of your body? Use cell division and differentiation in your answer.

Answers

Answer:

Once an egg is fertilized by a sperm, a zygote is formed. The zygote divides into multiple cells in a process known as cleavage, triggering the beginning of embryonic differentiation. Cells in these three layers will give rise to different parts of the organism. The endoderm eventually becomes the gut.

A zygote is formed when an egg is fertilized. The zygote divides into multiple cells in a process known as cleavage, triggering the beginning of embryonic differentiation.

What is Differentiation?

This is the process in which cells acquire different structure and function from one another to form distinct cell types.

When a zygote is formed, cell division takes place which helps to trigger differentiation of cells.
