Sofia’s favorite meal is breakfast, and she is careful to include healthy components along with her favorite foods. She knows breakfast helps to keep her energy levels up until lunch. Sophia's digestive system helps her body get energy from food. How do the nutrients from food get to the body's cells? A. The nutrients are distributed by the digestive system to the parts of the body that need them. B. The nutrients are picked up and transported around the body by blood from the circulatory system. C. The nutrients are absorbed directly into the cells that need them. D. The circulatory system brings nutrients to the digestive system to be processed for the cells.
Answer: c
Explanation:because it needs cells I think…
The nutrients from the food get to the cells of the body by the action of two organ systems i.e. the digestive system and the circulatory system.
What is the role of the digestive system?The digestive system may be defined as a type of organ system that significantly deals with the breakdown of food substances into simpler components that can easily be consumed by the body.
According to the context of the question, the food that we eat reaches the stomach through the esophagus where multiple enzymes perform their roles. After the stomach, the food may be passed to the small intestine which is absorbed here and then the nutrients assimilate in the blood.
Through the blood, the nutrient can be transported around the body by blood from the circulatory system. Thus, the correct option for this question is B.

objects are brought into focus on the retina by changes in the curvature and thickness of the
Objects are brought into focus on the retina by changes in the curvature and thickness of the lens.
What is eye lens?The lens basically directs light rays onto the retina. The lens is clear and replaceable if necessary. As we age, our lenses deteriorate, necessitating the use of reading glasses.
The lens is normally clear and is located behind the iris. The pupil directs light to the lens.
Small muscles attached to the lens can cause the lens to change shape, allowing the eyes to focus on objects that are close or far away.
Light bends (refracts) and focuses on the retina at the back of the eye as it passes through the lens.
The lens's thickness and curvature can be adjusted to focus on objects at various distances and ensure that the image is as clear as possible (this process is known as accommodation).
Thus, eye lens helps to focus the object.

The statement about the law of independent assortment which is correct is: C. It describes the inheritance of different genes relative to one another.
Independent assortment can be defined as a biological process through which the inheritance pattern of a particular gene doesn't affect the inheritance pattern of another gene.
This ultimately implies that, the inheritance pattern of different genes with respect to another gene is given by the law of independent assortment.
In conclusion, the law of independent assortment describes how different genes separate with respect to another gene during the development of reproductive cells.

which of the examples are considered anabolism? select all that apply.
Anabolism is for the synthesis of complex molecules essential in the building up of organs and tissues. It is therefore responsible for the increase in body size. Examples of anabolism are bone growth and mineralization, and muscle mass build-up.
Answer:
DNA nucleotide synthesis or polymerisation or condensation reactions;
Catabolism is breaking down of a larger molecule, so 1 large will become 2 or more smaller molecules;
Anabolism is the opposite, 2 or more smaller molecules will join together to form 1 larger molecules

The different forms matter can take are referred to as states or countries.
Answer:
Three States of Matter
Learning Objective
Describe the three states of matter
Key Points
Matter can exist in one of three main states: solid, liquid, or gas
The states of matterThis diagram shows the nomenclature for the different phase transitions.
Solids
A solid’s particles are packed closely together. The forces between the particles are strong enough that the particles cannot move freely; they can only vibrate. As a result, a solid has a stable, definite shape and a definite volume. Solids can only change shape under force, as when broken or cut.
In crystalline solids, particles are packed in a regularly ordered, repeating pattern. There are many different crystal structures, and the same substance can have more than one structure. For example, iron has a body-centered cubic structure at temperatures below 912 °C and a face-centered cubic structure between 912 and 1394 °C. Ice has fifteen known crystal structures, each of which exists at a different temperature and pressure.
A solid can transform into a liquid through melting, and a liquid can transform into a solid through freezing. A solid can also change directly into a gas through a process called sublimation.
Liquids
A liquid is a fluid that conforms to the shape of its container but that retains a nearly constant volume independent of pressure. The volume is definite (does not change) if the temperature and pressure are constant. When a solid is heated above its melting point, it becomes liquid because the pressure is higher than the triple point of the substance. Intermolecular (or interatomic or interionic) forces are still important, but the molecules have enough energy to move around, which makes the structure mobile. This means that a liquid is not definite in shape but rather conforms to the shape of its container. Its volume is usually greater than that of its corresponding solid (water is a well-known exception to this rule). The highest temperature at which a particular liquid can exist is called its critical temperature.
A liquid can be converted to a gas through heating at constant pressure to the substance’s boiling point or through reduction of pressure at constant temperature. This process of a liquid changing to a gas is called evaporation.
Gases
Gas molecules have either very weak bonds or no bonds at all, so they can move freely and quickly. Because of this, not only will a gas conform to the shape of its container, it will also expand to completely fill the container. Gas molecules have enough kinetic energy that the effect of intermolecular forces is small (or zero, for an ideal gas), and they are spaced very far apart from each other; the typical distance between neighboring molecules is much greater than the size of the molecules themselves.
A gas at a temperature below its critical temperature can also be called a vapor. A vapor can be liquefied through compression without cooling. It can also exist in equilibrium with a liquid (or solid), in which case the gas pressure equals the vapor pressure of the liquid (or solid).
A supercritical fluid (SCF) is a gas whose temperature and pressure are greater than the critical temperature and critical pressure. In this state, the distinction between liquid and gas disappears. A supercritical fluid has the physical properties of a gas, but its high density lends it the properties of a solvent in some cases. This can be useful in several applications. For example, supercritical carbon dioxide is used to extract caffeine in the manufacturing of decaffeinated coffee.
Phase Changes –What does a phase change look like at the molecular level? This video takes a look at the molecular structure of solids, liquids, and gases and examines how the kinetic energy of the particles changes. The video also discusses melting, vaporization, condensation, and freezing.
