Answer:
The nucleus has very important roles to play. As it contains genetic material, it coordinates cell activities like protein synthesis and cell division. Anatomically the nucleus is made up of several components: nuclear envelope, nuclear lamina, nucleolus, chromosomes, nucleoplasm are some of these components.
Explanation:
The nucleus controls and regulates the activities of the cellular (e.g., growth and metabolism) and carries the genes and systems that include the hereditary statistics.
What are the two number one capabilities of the nucleus?The nucleus has 2 primary features: it's miles responsible for storing the cell's hereditary cloth or the DNA. it is liable for coordinating the various essential cell activities along with protein synthesis, cellular division, growth, and a bunch of other critical features.

Thick Walled isodiametric dead cells
Answer:Sclerenchyma
Explanation:Sclerenchyma is thick walled dead lignified cells, they are hard and elastic. The sclerenchyma cells are divided into two groups namely fibers and sclereids. Sclerenchymatous fibers are branched/unbranched, long, hard, pointed cells with tapering ends, thick walls, and narrow lumen.
Answer:
Sclerenchyma is Greek word where "Sclero-" means hard and "enchyma" means infusion. This tissue consists of thick-walled, dead cells and protoplasm is negligible. These cells have hard and extremely thick secondary walls due to uniform distribution and high secretion of lignin and have a function of providing mechanical support

When placed in water, oil does not dissolve and stays separate. This means oil is_____ and ____.
Answer:
when placed in water, oil does not dissolve and stays separate. this means oil is immiscible and inorganic
Explanation:
When placed in water, oil does not dissolve and stays separate. This means oil is a non-polar and hydrophobic substance.
What are oils?Oils are organic compounds. They are nonpolar chemical substances that are made up of hydrocarbons. They're flammable, and they're extracted from vegetables plants, and animals.
Oils are not soluble in water because they are hydrophobic in nature, doubt a layer of oils is made of made up of a hydrophobic chain that is insoluble in water.
Substances are nonpolar substances are those substances which are insoluble in water. Oil is one of them. Polar substances are dissolved in water because they have hydrophilic ends.
Thus, oil does not dissolve in water and remains separate. Oil is a non-polar, hydrophobic substance, according to this.

What are sound waves
Answer:
Sound is a mechanical wave that results from the back and forth vibration of the particles of the medium through which the sound wave is moving. The motion of the particles is parallel (and anti-parallel) to the direction of the energy transport. This is what characterizes sound waves in air as longitudinal waves.
Answer:
Sounds waves are a type of energy that is manipulated by vibrant energy. Different variations of vibrant energy allows us to hear different sounds.

Why do globes lean sideways?
A.To allow them to spin easier
B.To demonstrate gravity
C.To demonstrate the passing of the seasons
D.To demonstrate the tilt of the Earth's axis
Answer:
D
Explanation:
Globes lean sideways To demonstrate the tilt of the Earth's axis. Option D is correct.
Globes lean sideways to demonstrate the tilt of the Earth's axis. The Earth is tilted on its axis by about 23.5 degrees. This tilt is what causes the changing seasons on Earth.
When a globe is tilted, it helps us visualize how different parts of the Earth receive different amounts of sunlight at different times of the year. For example, during the summer in the northern hemisphere, the North Pole is tilted towards the Sun, so it receives more direct sunlight and experiences warmer temperatures. At the same time, the South Pole is tilted away from the Sun, receiving less direct sunlight and experiencing winter.
By showing the tilt of the Earth's axis, globes help us understand why we have seasons and why they occur at different times in different parts of the world.
To summarize, globes lean sideways to demonstrate the tilt of the Earth's axis, which helps us understand the changing seasons on Earth. Option D is correct.

are made of multiple organs that work
together to maintain homeostasis in an organism.
Answer:
systems
Explanation: Cells are organized into tissues, and tissues form organs. Organs are organized into organ systems such as the skeletal and muscular systems. All of the organ systems of the body work together to maintain homeostasis of the organism. If homeostasis fails, death or disease may result.
Organ systems are made up of multiple organs that work together to maintain homeostasis in an animal or multicellular animals. In animals, organ systems are seen, which coordinate to form an organism.
What is an organ system?Multicellular animals are made up of multiple cells, and these cells work together to make a tissue. All the cells in a tissue have a single function, such as epithelial tissue or nervous tissue; these tissues form the organs. An example is the stomach, which is made up of different types of tissue such as longitudinal smooth muscle, circular smooth muscle, etc.
These organs collaborate to form organ systems like the digestive system, which includes the stomach, small intestine, pancreas, liver. Organs such as the stomach digest food in the organ system, and the small intestine aids in the process by allowing it to absorb into the blood along with digestion. Organ systems are interdependent, such as the digestive system, which is dependent on the nervous system, the circulatory system, and so on.
hence Organ systems are made up of multiple organs that work together to maintain homeostasis.

Which of the following groups of organisms uses sunlight to convert carbon dioxide and water into sugar and oxygen?
a. producers
b. decomposers
c. carnivores
d. herbivores
The group of organisms which uses sunlight to convert carbon dioxide and water into sugar and oxygen are producers. Thus, the correct option is A.
What are Producers in the ecosystem?Producers are any kind of green plants present in the ecosystem. Green plants make their own food by using the sunlight (solar energy) and carbon dioxide gas from the atmosphere with the energy to make sugar. The plant uses this sugar (carbohydrate), also called as glucose to make many different products, such as wood, leaves, roots, and bark.
This process through which plants produce their food is called photosynthesis. Photosynthesis occurs only in the plants which have chlorophyll pigment (chloroplast).
