Answer:
The biology Molecules that will.be present in what she consumed are Carbohydrates from unbuttered bread, vitamins green spinach, Fat and oil or lipids from sunflower seeds, proteins...
The Carbohydrates is processed into glucose, proteins is processed into amino acids, lipids is processed into fatty acids and glycerol.
Explanation:
From the food consumed, The biology Molecules that will.be present in what she consumed are Carbohydrates from unbuttered bread, green spinach contains vitamins like vitamin K, vitamin A, vitamin C, vitamin B12 , minerals like magnesium, iron, Fat and oil or lipids from sunflower seeds, proteins...
The Carbohydrates is processed into glucose after enzymes like salivary amylase acts on it from the chewing and in the stomach which produces glucose which makes it easily absorbable , proteins is processed into amino acids by the activity of hydrochloric acids and protease that processed it into amino acids, lipids is processed into fatty acids and glycerol by the activities of the enzymes lipase.
The minerals and vitamins present are in a way they can be absorbed.
The molecules that will be present in the foods shown above would be sugar, carbohydrates, lipids, fiber, vitamins, calcium, phosphorus, potassium, proteins, and magnesium.
We can arrive at this answer because:
French bread will supply the body with carbohydrates. These carbohydrates will be turned into sugars, mainly glucose.The proteins present in spinach will be transformed into amino acids that will be used in the production of other proteins.The lipids present in sunflower seeds will be transformed into fatty acids, glycerol, and fat.The calcium present in spinach will be absorbed by the bones.Vitamins, phosphorus, and potassium will be broken down and dissolved in the bloodstream.Fiber will be metabolized by the intestine.Based on this, we can say that proper nutrition is important because it promotes essential molecules for the functioning of the body.

B) is the answer of question
D. Each ecosystem has a preferred disturbance frequency, Disturbances that occur at the right frequency, not too frequent or infrequent, will promote diversity at the landscape scale. Disturbances that are too frequent or to infrequent will result in biodiversity decreases.
What is biodiversity?Biodiversity refers to the variety and abundance of different species that exist within an ecosystem or region. It includes the diversity of different species, as well as the diversity within species (such as genetic diversity) and the diversity of ecosystems.
Biodiversity is important because it helps to maintain the health and functioning of ecosystems, and it is also a source of economic, cultural, and recreational value. Biodiversity can be affected by a variety of factors, including habitat loss, pollution, climate change, and the introduction of non-native species.
Disturbances are a natural part of ecosystems, but that the frequency of disturbances can affect the diversity of species in the ecosystem. It also suggests that each ecosystem has its own "preferred" disturbance frequency, and that disturbances that occur at the right frequency can promote biodiversity, while disturbances that are too frequent or too infrequent can lead to decreases in biodiversity.

what structures are found in every living cell
Answer:
The parts include a plasma membrane, cytoplasm, ribosomes, and DNA.
Explanation:
The structures found in every living cell are:
Plasma membraneCytoplasmDNACells are the smallest anatomical unit of organisms that perform all the characteristic functions of living beings, their structures are functionally related in order to keep the cell alive and reproduce it.
The outer limit of the cell is the plasma membrane.
It has two basic functions:.
• Receive signals from the environment or from other neighboring cells.
• Be a selective barrier of substances, allowing to concentrate those that the cell needs for its metabolism and to eliminate its waste.
The cytoplasm is the compartment found inside the plasma membrane, which consists of an aqueous substance in which various molecules and macromolecular complexes are immersed, as well as different types of organelles.
All living cell store in the form of DNA, deoxyribonucleic acid, the information necessary to control their activities (reproduction, metabolism), and to establish their own structure. DNA is a polymer formed by a linear sequence of monomers, called nucleotides.
Therefore, we can conclude that the main structures found in every living cell are the plasma membrane, and the compartment that it encloses, called cytoplasm, which contains the hereditary material (DNA), where cellular activities are governed.

Grapes growing on a vine are observed to shrink slightly during the day and increase in size at night. This is because:
a. developing fruits, such as grapes, transpire a lot of water to stay cool.
b. photosynthesis to produce sugar occurs in the light, but respiration and, therefore, the growth of new cells occurs mostly in the dark.
c. in leaves, phloem flow to growing sinks only occurs when the stomata are closed, because the transport capacity of the xylem is too small to supply water for both transpiration and phloem flow.
d. during the day, transpiration pulls on the water in the whole plant, causing the grapes to shrink slightly.
Answer:
d. during the day, transpiration pulls on the water in the whole plant, causing the grapes to shrink slightly.
Explanation:
Grapes are planted in later winter or in early spring seasons and they continue their growth in the summer months. During their growth, the grapes shrink a little during the day and gain in size at night. This phenomenon is due to the grape cells are composed of a hypertonic (concentrated) sugar solution that during the day lost water by osmosis, thereby shrinking the cytoplasm.

Explanation:
The analysis of data gathered during a particular experiment is necessary in order to arrive at a conclusion that will address the aim of the experiment.
Without data analysis, valid conclusions about the experiment cannot be made and what the experimenter would have is just raw data that cannot say or answer anything about the experiment.
The data collected from experiments can be analyzed in two ways:
Descriptive data analysis Inferential data analysisIn descriptive data analysis, the collected data is summarized, arranged, or described in such a way that a pattern can be seen at a glance. It includes tables, charts, histograms, etc.
In inferential data analysis, the collected data is treated in such a way that an inference can be arrived at based on the study. This includes testing for a significant difference between means, testing for the goodness of fits, correlations, etc.

Both photosynthesis and cellular respiration are part of the carbon cycle. Which statement best compares these two processes? Both release carbon dioxide as waste. Both provide organisms with usable energy. Both add bacteria to the soil. Both require fixation in order to convert molecules.
Answer:
Both provide organisms with usable energy.
Explanation:
Both photosynthesis and cellular respiration, a component of the carbon cycle provides an organism with usable energy.
Photosynthesis is the process whereby green plants manufacture their food using carbon dioxide and water using sunlight to produce energy rich glucose and oxygen gas as a by-product.
During cellular respiration is an oxygen driven aerobic process in which organisms breaks down glucose to produce energy rich ATP.
Both processes furnishes an organism with energy in the end. Although, photosynthesis is an energy building process, cellular respiration breaks down materials to liberate energy. This energy is used by both plants and animals for their living activities.Therefore, photosynthesis and cellular respiration provides an organism with usable energy.

and hypertonic solutions.
PLEASE HELP ASAP!! WILL MARK BRAINLIST TO FIRST WHO ANSWERS!
hypertonic is when blood cells shrivel under hot temperatures
isotonic is equilibrium between concentration of blood and salt
hypotonic is less concentration on outside compared to inside
Answer:
When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell. ... If placed in a hypotonic solution, a red blood cell will bloat up and may explode, while in a hypertonic solution, it will shrivel—making the cytoplasm dense and its contents concentrated—and may die.
