Explanation:

Answer:

Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that acceleration is a change in velocity.

Explanation:

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.

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.

Answer: The answer is A and D

Explanation:

Jus pick it if you trust me

Two statements that describe evidence that directly led to the development of the theory of plate tectonics? a) Sonar confirmed the presence of mid-ocean ridges. d) Seismic data showed that most earthquakes and volcanoes occur where crust is being formed or destroyed.

According to this theory, the earth's surface is separated by plates that move above the molten mantle. Over the plate borders, these plates interact with one another, causing friction.

Seismic surveys provide a scan of the earth's subsurface using reflected sound waves.

By knowing the speeds at which seismic waves move through rocks at various places and depths, we can learn about geologic formations on the earth. and describes the way an area will tremble during an earthquake.

Hence, options (a) and (d) are correct.

Cytoplasm

Explanation:

The Cytoplasm is a Jelly-like substance, where chemical reactions take place.

Answer:

Explanation:

ANSWER

If the number of electrons in the outermost shell of an atom of an element is less than or equal to 4, then the valency of an element is equal to the number of electrons in the outermost shell.  

If it is greater than 4 then, the valance is determined by subtracting the outermost shell of electrons from 8.

The electrons in Cl, S, and Mg are 2,8,7 ; 2,8,6 ; 2,8,2  

Hence the valency of Cl, S, and Mg are 1, 2, 2 respectively.

Answer:

Chlorine has 7 valence electrons

Magnesium has 2 valence electrons

Sulphur has 6 Valence electrons

Explanation:

We can find how many valence electrons by looking at the periodic table. For instance chlorine is a halogen and therefore has 7 valence electrons as it is in group 17. Magnesium is in group 2 so therefore has 2 valence electrons.

Sulphur is in group 16 and therefore has 6 valence electrons.

If the group has double digits I.e 16 like sulphur we only look at the second digit i.e. 6 as we can't have more than 8 valence electrons.

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.

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.

The mouth covered by chitin and intracellular granules of chitin (i.e. spindles) in nudibranchs

Explanation:

Nudibranchs are marine gastropod molluscs (Opisthobranchia, Mollusca). These organisms are carnivorous, so they feed on sponges, coral, anemones, hydroids, fish eggs, etc. On the other hand, cnidarians have specialized cells called cnidoblasts or cnidocytes that contain nematocysts made up of toxins that serve as a defense mechanism. Nematocysts are found in many species of Cnidarians such as, for example, in the tentacles of sea anemones. Interestingly, nudibranchs have developed some adaptations for feeding on these species. In the first place, nudibranchs have the mouth covered by a substance named chitin that allows them to chomp and swallow anemone tentacles. Second, they (nudibranchs) also have intracellular granules of chitin (i.e. spindles) in the digestive system that function as biological sandbags which maintain nematocyst toxins away from sensitive body parts.

The mucus coat of clownfish protects the fish from sea anemone's sting which is an adaptation clownfish developed.

Nematocysts are cells found in which is use for locomotion and for defence and capturing prey.

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.

The most difficult property of a soil to modify is fertility, while the easiest property to modify is texture.

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.

Some of the soil properties are:

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.
