In digestion, where are molecules coming from? *
a.From food the animal eats
b.From the blood
c.From the cells
Answer:
In digestion molecules come from food the animal eats (option a).
Explanation:
Foods that are consumed are those that provide the necessary molecules for the maintenance of the organism. The process of digestion consists of converting food into molecules —amino acids, glucose and fatty acids— that are easily absorbed by the body.
When an animal eats food, its digestive system is in charge of processing it and converting it into simple molecules, necessary to cover its requirements.
what are the defense mechanisms of the human body
Explanation:
The human body has three primary lines of defense to fight against foreign invaders, including viruses, bacteria, and fungi. The immune system's three lines of defense include physical and chemical barriers, non-specific innate responses, and specific adaptive responses.
The human body possesses several defense mechanisms to protect itself against pathogens (disease-causing microorganisms) and other harmful substances such as innate and adaptive immune system.
Innate immunity is the body's first line of defense and is present from birth. It provides immediate protection against a wide range of pathogens. Adaptive immunity is a specific defense mechanism that develops over time in response to specific pathogens. It provides long-lasting immunity and has the ability to recognize and remember specific pathogens. Both innate and adaptive immunity work together to provide a comprehensive defense against pathogens. Innate immunity provides rapid, general protection, while adaptive immunity offers specific, targeted responses. The coordination between these defense mechanisms helps the body combat infections and maintain overall health.

3. In what landscape feature are metamorphic rocks generally found?
Answer:
Although metamorphic rocks typically form deep in the planet's crust, they are often exposed on the surface of the Earth. This happens due to geologic uplift and the erosion of the rock and soil above them. At the surface, metamorphic rocks will be exposed to weathering processes and may break down into sediment.

In what organelle the chloroplast process occur in
Answer:
It occurs in the green tissue.
Explanation:
they are concentrated particularly in the parenchyma cells of the leaf mesophyll.
Answer:
Photosynthetic cells contain special pigments that absorb light energy. Different pigments respond to different wavelengths of visible light. Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly.In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle. In electron micrographs, thylakoid membranes look like stacks of coins, although the compartments they form are connected like a maze of chambers. The green pigment chlorophyll is located within the thylakoid membrane, and the space between the thylakoid and the chloroplast membranes is called the stroma (Figure 3, Figure 4).
Chlorophyll A is the major pigment used in photosynthesis, but there are several types of chlorophyll and numerous other pigments that respond to light, including red, brown, and blue pigments. These other pigments may help channel light energy to chlorophyll A or protect the cell from photo-damage. For example, the photosynthetic protists called dinoflagellates, which are responsible for the "red tides" that often prompt warnings against eating shellfish, contain a variety of light-sensitive pigments, including both chlorophyll and the red pigments responsible for their dramatic coloration.
Photomicrographs of chloroplasts with structures labeled are shown alongside a simplified illustration of a photosynthetic cell with a prominent chloroplast. A portion of the chloroplast illustration is depicted enlarged next to the cell to show the structure of a granum, which consists of stacked thylakoids.
Figure 4: Diagram of a chloroplast inside a cell, showing thylakoid stacks
Shown here is a chloroplast inside a cell, with the outer membrane (OE) and inner membrane (IE) labeled. Other features of the cell include the nucleus (N), mitochondrion (M), and plasma membrane (PM). At right and below are microscopic images of thylakoid stacks called grana. Note the relationship between the granal and stromal membranes.

What Are the Steps of Photosynthesis?
Photosynthesis consists of both light-dependent reactions and light-independent reactions. In plants, the so-called "light" reactions occur within the chloroplast thylakoids, where the aforementioned chlorophyll pigments reside. When light energy reaches the pigment molecules, it energizes the electrons within them, and these electrons are shunted to an electron transport chain in the thylakoid membrane. Every step in the electron transport chain then brings each electron to a lower energy state and harnesses its energy by producing ATP and NADPH. Meanwhile, each chlorophyll molecule replaces its lost electron with an electron from water; this process essentially splits water molecules to produce oxygen (Figure 5).
An illustration shows the light and dark reactions for photosynthesis drawn on top of a simplified image of a chloroplast, represented as an oviform capsule. Inside the capsule are five stacks of three or four flat, green thylakoid discs. The discs look like stacked quarters. Two thylakoid stacks have been cut away so that their interiors, which are hollow, are visible.
Figure 5: The light and dark reactions in the chloroplast
Photosynthetic cells contain chlorophyll and other light-sensitive pigments that capture solar energy. In the presence of carbon dioxide, such cells are able to convert this solar energy into energy-rich organic molecules, such as glucose. These cells not only drive the global carbon cycle, but they also produce much of the oxygen present in atmosphere of the Earth. Essentially, nonphotosynthetic cells use the products of photosynthesis to do the opposite of photosynthesis: break down glucose and release carbon dioxide.

1. Which aspects of soil do you think are easiest to change? Which are more difficult
change? Why?
The most difficult property of a soil to modify is fertility, while the easiest property to modify is texture.
What is the ground?Soil is the surface part of the earth's crust, biologically active, which comes from the disintegration or physical or chemical alteration of the rocks and the residues of the activities of living beings that settle on it.
What are the main properties of the soil?Some of the soil properties are:
Texture. Soils vary among themselves according to the elements that constitute them and their texture changes according to the quantity and size of the particles that form it.Fertility. Soils vary among themselves according to their level of fertility, that is, according to their ability to support plant life.PH. Soils vary from each other according to their level of acidity (pH). The pH is measured on a scale that goes from 1 to 14, with 7 being a neutral pH, less than 7: acidic and greater than 7: basic.Mutation. Soils change over time and due to factors such as the decomposition of organic waste, excessive rainfall, among others.Permeability. Soils vary among themselves according to their permeability, that is, the ability to filter water and air.Structure. Soils vary among themselves according to the way in which the elements and materials that constitute them are grouped.Salinity. Soils vary among themselves according to the percentage of accumulated soluble salts they have.Porosity. The soils vary among themselves according to the number and structure of the pores, which are those soil spaces that are empty, that is, they are not formed by solid matter, but by water and air.What is the easiest and most difficult soil property to modify?The easiest property to modify of the floor is the texture because if we want a more rigid or softer floor we can replace it with any material that is available for that purpose. However, this does not guarantee other properties such as fertility, salinity, good pH, among others.
On the other hand, the most difficult soil property to modify is fertility, since this property is the result of very specific physical and chemical processes. For example, we cannot modify the fertility of the soil of a desert.

Why are chromosomes important to mitosis?
Answer:
The daughter cells need a copy of every chromosome in order to replicate and separate.
Explanation:
Cells have to replicate their genetic material to make a whole other cell. Before mitosis the cells need this step for mitosis.
Answer:
The fundamental importance of chromosomes is that they contain DNA, or deoxyribonucleic acid, the substance that contains every organism's genetic code. When a cell divides, its chromosomes must first replicate. Cells divide in two basic ways – mitosis and meiosis. The latter type of division incorporates the former.
