Final answer:
Nervous tissue consists of neurons and glial cells, specialized for sending and receiving electrochemical signals in the CNS and PNS. It includes gray matter and white matter, with neurons being the primary communicators supported by glial cells.
Explanation:
Tissue found in the central nervous system (CNS) and peripheral nervous system (PNS) that contains neurons and glial cells is called nervous tissue. Nervous tissue is unique because it is capable of sending and receiving electrochemical signals that provide the body with information. Neurons are responsible for communication through electrical signals and are supported by glial cells, which maintain the environment around the neurons to ensure proper function.
Nervous tissue is characterized by two types of regions within the nervous system structures: gray matter, predominantly containing cell bodies and dendrites, and white matter, composed largely of axons. The myelin sheath, a lipid-rich substance, insulates the axons and gives white matter its characteristic color. This structural organization is essential for the communication function of the nervous system, making neurons the more functionally significant cells.

- regardless of how many colors you observed, explain why some pigments (in plants with more than one) move further than others.
Final answer:
The behavior of pigments moving differently in plants is due to their unique properties of absorbing specific wavelengths of light while reflecting others. Chlorophylls and carotenoids, the major photosynthetic pigments, absorb and reflect different wavelengths, leading to their distinct movement patterns when subjected to experiments such as chromatography.
Explanation:
The question asks why some pigments in plants move further than others, despite having more than one color observed. This phenomenon can be attributed to the unique absorption and reflection properties of different pigments. Photosynthetic pigments, such as chlorophylls and carotenoids, are crucial in this process. Each pigment type absorbs only specific wavelengths (colors) of visible light and reflects or transmits the wavelengths they cannot absorb. Chlorophyll a, for example, absorbs light in the blue-violet region, while chlorophyll b absorbs red-blue light, and both reflect green light. Carotenoids absorb light in the blue-green and violet regions and reflect the longer yellow, red, and orange wavelengths. This selective absorption and reflection of light not only explains the varying colors of plants but also why certain pigments move differently in experiments like chromatography, where these differences in light absorption can cause pigments to travel at different speeds or distances when dissolved.
What product of the Krebs cycle is considered a waste product of the reaction?
Carbon dioxide is considered as a waste product of Krebs Cycle.Before Krebs cycle begins pyruvic acid which has 3 carbon splits into two parts. Two carbon atom combines with co enzyme A and forms a compound called acetyl-co enzyme A.The third carbon atom left combines with oxygen to form carbon dioxide which is a by product of this cycle.The carbon dioxide formed here diffuses into the bloodstream and then carried to the lungs for exchange of gas.
The waste product of the Krebs cycle (also known as the citric acid cycle or tricarboxylic acid cycle) in biology is carbon dioxide (CO2). This is produced as a result of the breakdown of citrate during the cycle, and is expelled from the cell and exhaled by the organism.
Explanation:In biology, the Krebs cycle, also known as the citric acid cycle or the tricarboxylic acid cycle, is an important part of cellular respiration. During this cycle, acetyl CoA, a two-carbon molecule, combines with a four-carbon molecule called oxaloacetate to form a six-carbon molecule called citrate, or citric acid. As the cycle continues, citrate is oxidized, or broken down, to release high energy products like NADH, FADH2, and ATP or GTP, depending on the cell type.
Now, when referring to the waste product of the Krebs cycle, it is important to note that carbon dioxide (CO2) is produced during the cycle. For every acetyl group that enters the cycle, two carbon dioxide molecules are released. These carbon dioxide molecules are considered a waste product because they are not used within the cell for other metabolic processes. Instead, they are expelled from the cell and exhaled by the organism.
So, in summary, the primary product of the Krebs cycle that's considered a waste is carbon dioxide (CO2).

What poses a greater threat to the entire human species; poisonous abiotic factors or poisonous biotic factors? And why?
PLZ HELP ME. I'LL LOVE YOU FOREVER
Answer: Poisonous abiotic factors poses a greater threat to the entire human species.
The abiotic factors are the non-living components of the environment. The life of biotic (living) factors is dependent upon these abiotic factors. The abiotic factors includes water, air, soil. Natural or human induced changes in the abiotic factors can be responsible for human population destruction on a large scale. Water being an abiotic component, the life of different life forms including humans is dependent upon it. Water sources (river, lakes, ponds) if contaminated due to human activities like agriculture and industrial wastes, water transportation wastes which are left in water body. These waste pollutants can be poisonous and produces deleterious effects on human population after consumption hence, may lead to mass elimination of human population. Air may get polluted with poisonous gases like nitrogen, sulphur dioxide, methane, carbon monoxide, carbon dioxide, chlorofluorocarbons. These gases releases as vehicular pollutants, green house gases, natural gas explosion, volcanic eruption can be responsible for mass destruction. Therefore, poisonous abiotic factors poses a great threat to the entire human species.

You went on vacation and forgot to water your plants. when you returned, the leaves were soft and wilted. name the organelle that became dehydrated
The organelle that becomes dehydrated when a plant is not watered is the central vacuole. This results in the leaves becoming soft and wilted due to the loss of turgor pressure, which can be restored by re-watering the plant.
When you returned from vacation and found the leaves of your plants soft and wilted, the organelle that became dehydrated is the central vacuole. The central vacuole in plant cells is critical for maintaining turgor pressure, which is the pressure of the cell's contents against the cell wall that keeps the plant rigid and upright. When a plant is not watered, the water concentration in the soil becomes lower than inside the plant; consequently, water moves out of the central vacuoles and cytoplasm, causing the vacuoles to shrink. This results in the loss of turgor pressure, leaving the cell wall unsupported and causing the plant to wilt.
It is analogous to a balloon deflating inside a cardboard box. When inflated, the balloon (vacuole) pushes against the sides of the box (cell wall), keeping it firm. As the balloon loses air (water), it stops supporting the box, leading the structure to droop. Re-watering the plant allows the central vacuoles to reabsorb water, re-expand, and re-pressurize the cells, restoring the plant's structure and its ability to stand upright, resisting the force of gravity.

how does chemical weathering make it easy for mechanical weathering to occur
Answer:
Chemical weathering can make mechanical weathering easy by changing the chemical composition of the rock.
The mechanical weathering of hard rocks is tough and takes time and the mechanical weathering of soft rocks takes less time.
The softness and hardness of the rocks depends on the chemical composition of the rocks. The chemical weathering changes the chemical nature of rocks and hence makes it easier to break down into smaller portions.
