Identify the true statements below.
The reaction of an exploding firework occurs at a faster rate than a burning candle.
The activation energy required for an exploding firework is less than the activation energy required for a burning candle.
Answer:
In the explanation-----
Explanation:
The first statement is correct since the gun explosive powder explodes since they light a fuse at first, and once the fuse reaches the end it explodes as a reaction. However, for a candle it relies on the lit fire. Wax is a tough and a longer substance to melt compared to a exploding firework.
For the activation energy for the firework, it uses that energy in a result of the fuse reaching the end and reacting with the gun powder.
Answer:
A is the correct answer

How do substances get into and out of the cell?
Answer:
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.

What are cell cycle regulators
Answer:
Cell cycle regulators are the cell cycle only when they are tight bound to CDKS.
Explanation:
To be fully active, the CDK/Cyclin complex must also be phosphorylated in specific locations. Like all kinases, CDKS are enzymes (kinases) that phosphorylate other proteins. Phosphorylation activates the protein by changing its shape.

In a woodland ecosystem, the number of species of microorganisms in the soil that do not
harm plants increases. How does this rise in biodiversity affect the sustainability of the
ecosystem?
A The rise in biodiversity makes the ecosystem less sustainable.
B The rise in biodiversity makes the ecosystem more sustainable.
C The rise in biodiversity does not change the sustainability of the ecosystem.
D The rise in biodiversity makes the ecosystem only temporarily less sustainable.
Answer:
I think it’s B
Explanation:
Veteran trees are home to a variety of invertebrate species because a woodland's diversity is essential (insects, spiders, millipedes, centipedes, etc.), Thus, option B is correct.
What is the rise in biodiversity in woodland ecosystem?In addition to lichens and fungi. Mature forests also favor bats among other species. Biodiversity in the woodland is a result of structural diversity.
Stability increases with biodiversity in ecosystems, species, and people. For instance, species with numerous populations that are adapted to a wide range of conditions and high genetic diversity are more likely to be able to withstand disturbances, disease, and climate change.
Generally speaking, expanding the variety of habitats or vegetation structures present at a site can be done to increase biodiversity.
Therefore, The rise in biodiversity makes the ecosystem more sustainable.

What are types of protein ?Like carbohydrates and fats, Proteins are the macronutrient as it provides the body with energy and is essential to building muscle mass., The protein of body made up of 20 different amino acids.
These amino acids are classified into 2 categories such as Non-Essential Amino Acids produced naturally by the body and Essential Amino Acids (EAAs) not produced naturally by the body, consumed through food or supplementation.
Both animal and plant proteins we consume, Most animal proteins are complete proteins, meaning they have all 9 of the essential amino acids (EAAs) but plant proteins are incomplete proteins , they have at least one missing amino acid.

A. By producing insulin
Answer:
C. By storing glucose
Explanation:
By storing glucose, the liver makes sure that blood glucose levels remain steady between meals and during sleep. When blood glucose falls, cells in the pancreas secrete glucagon. Glucagon instructs the liver to convert glycogen to glucose, making glucose more available in the bloodstream.
