Answer:
This question lacks options, the options are:
A) Saliva converting the starch molecules in crackers into simple sugars
B) Digestive enzymes breaking down proteins into smaller fragments
C) bacteria converting lactose into simple sugars in the intestines
D) teeth grinding an almond into smaller pieces in the mouth
The answer is D
Explanation:
A physical change is a change that occurs to a substance without altering its chemical composition. A physical change involved a change in the substance's shape, texture, color, state etc. but not the chemical content of such substances.
In this question involving the processes that occur in digestion, a typical example of physical change is "teeth grinding an almond into smaller pieces in the mouth" because the teeth only changes the shape and texture of the almond. It does not affect the chemical composition of the almond fruit. This is also called mechanical digestion.
Note that, other options involving digestive enzymes breakdown are chemical changes because the enzymes breakdown the chemical components of each substance.
Answer: D
Explanation: because you are breaking down food in a physical change

Which processes provides evidence for the claim that energy is transferred
during cellular respiration? Select all correct answers.
A. The electron transport chain
B. Carbon dioxide is released
C. hydrogen ions move down the concentration gradient across the inner membrane
D. transfer of electron carriers such as NADHand FADH2
E. water is formed
Answer:
B. Carbon dioxide is released
E. water is formed
Explanation:
Cellular respiration is defined as the metabolic processes in which chemical energy is converted into ATP and the waste product is released by the cells.
The processes that provide evidence for the claim that energy is transferred during cellular respiration are Carbon dioxide is released and water is formed. During cellular respiration, oxygen and glucose are converted into carbon dioxide and water, and the energy is transferred to ATP.
Hence, the correct answers are "B and E".

Where does the waste material in the body come from and why does the body need to get rid of these waste materials? Please help me!
Answer:
These waste materials are excreted out by the process of diffusion through general body surface. The removal of waste will help prevent the body from becoming ill, it will help clean the body inside and out, and will protect the body from infections.

How is a hybrid different from its originating crops?
A hybrid crop is different from the original crops as they contain genes from other crops that are beneficial for them.
A hybrid has the genetic makeup of both of its parent crops but may have completely distinct external characteristics. This is due to the fact that two recessive genes from both parent crops can be fused together to create an outward visible impact in the hybrid.
Hybrid plants are the result of the cross-pollination of two plant varieties and the propagation of the seed resulting from the mix. The plant that emerges from this seed combination is known as a hybrid plant.

What are the subunits (monomers) of DNA and their function? O Monosaccharides that provide quick energy for the cell. O Lipids that store energy and provide insulation. O Proteins that provide the building blocks for the structures of organisms. O Nucleotides that store information.
Answer:
Nucleotides that store information
Explanation:
Deoxyribonucleic acid, commonly known as DNA, is one of the two nucleic acid biomolecules found in living systems. DNA is a polymer made up of long chains of monomeric units called NUCLEOTIDES. Nucleotides consists of three major subunits or parts namely: phosphate group, nitrogenous base (A,T, G, C) and a five-carbon sugar (deoxyribose).
Nucleotides are responsible for the functional and structural characteristics of DNA, which is to store GENETIC INFORMATION in living cells.
Bees, which are known for aiding in pollination, help with which process?
A. enabling pollen to grow fruit to encase the sperm and egg
B. enabling pollen to grow a tube to transfer sperm to the egg
C.transferring pollen from the anther to the pistil
D. transferring pollen from the ovule to the ovary
Please hurry and answer for me plz!
Bees, which are known for aiding in pollination, help with transferring pollen from the anther to the pistil. The correct option is C.
What is pollination?Transferring pollen grains from a flower's male anther to its female stigma is the process of pollination.
Every living thing, including plants, strives to produce progeny for the following generation. Making seeds is one method through which plants can create progeny.
Bees are necessary for the growth of plants and flowers. They use the pollination process, in which they move microscopic pollen grains from one blossom of one sort of plant to another flower of the same kind.
The transfer of this pollen aids in the growth of the blooms which will ensures that a plant will produce full-bodied fruit and a full set of viable seeds.
Thus, the correct option is C.

For any natural ecosystem, which of the following statements applies to the energy pyramid, the biomass pyramid, and the pyramid of numbers? *
1 consumes are at the bottom of the energy pyramid only
2 consumers form the bottom levels and producers are at the top
3 producers at the bottom of the biomass and energy pyramids only
4 producers are at the bottom of all three pyramids as they are the basis of all food chains and webs
Answer:
4
Explanation:
Producers are at the bottom of the energy pyramid because they prove the most energy, they make up most of the population, which is biomass. And the producers have the largest population, which is why they are at the bottom of the pyramid of numbers. Finally they are at the bottom of food chains and webs because they store the most energy inside of them.

PLEASE HELPPP I WILL GIVE BRAINLIEST What effect does starvation or suffocation have on the process of cellular respiration and how would this affect the organism as a whole. include these words: carbon dioxide, glucose, oxygen, water, ATP, reactant, product, food, fermentation, and anaerobic respiration. Please helppp
Answer:
Explanation:
This question seeks to test the knowledge of anaerobic respiration during the process of glycolysis. During intense exercise (or suffocation) the energy/ATP produced (for the short period of about 2 minutes) is as a result of the breakdown of glucose in the absence of oxygen (known as anaerobic glycolysis).
When an individual is fasting or experiencing starvation, the glycogen storage is quickly converted to glucose and then released into the body for cellular breakdown or respiration for the production of energy or ATP. Glycolysis leads to the formation of pyruvate; during suffocation/exercise, the pyruvate (serves as reactant) undergoes fermentation to either produce lactate in humans or ethanol and carbon dioxide in yeast cells (where lactate, ethanol and carbon dioxide serve as products).
Hence, starvation can be said to deplete glycogen storage while suffocation or anaerobic respiration (breathing in the absence of oxygen) causes the cellular breakdown of glucose (glycolysis) to be anaerobic. However, when the glycogen storage starts getting depleted, stored lipids starts getting converted to energy also in the presence of water in body.
It should be noted that the glucose (which is stored as glycogen) is synthesized/obtained from the food we eat.
