Explanation:

The false statement about epigenetic modifications is:
c. Only non-DNA components of chromatin are modified with epigenetic markers.

Epigenetic modifications refer to changes in gene expression that do not involve changes to the underlying DNA sequence. These modifications can be inherited and can influence how genes are turned on or off in different cells or at different stages of development.

a. The tails of the nucleosome octamer components can be modified with methylation: This statement is true. Methylation of the tails of nucleosome octamer components, which are made up of histone proteins, can affect gene expression by either activating or repressing the associated genes.

b. The tails of the nucleosome octamer components can be modified with acetylation: This statement is also true. Acetylation of histone tails is another type of epigenetic modification that can influence gene expression. Acetylation generally leads to gene activation by relaxing the chromatin structure and allowing transcription factors to access the DNA.

d. Epigenetic modifications control whether a region is euchromatin or heterochromatin: This statement is true. Epigenetic modifications play a crucial role in determining whether a region of DNA is in a euchromatin state, which is more accessible for gene expression, or a heterochromatin state, which is more condensed and less accessible for gene expression.

In summary, the false statement is c. Only non-DNA components of chromatin are modified with epigenetic markers. Epigenetic modifications can occur on both DNA and non-DNA components of chromatin, such as histone proteins. These modifications can have significant impacts on gene expression and are essential for cellular development and function.

Answer:

A number of tiny hair like bristlez are present on the lower surface pf an earthworm's body. These bristles help it to get a good grip on the surface of q ground.However these bristles donot provide good grip on plain glass tiles.

Earthworms have microscopic hairs or bristles all over their body which provide the necessary traction while movement. These bristles or setae are present on each segment of their body and it imparts the necessary grip or anchorage for forward and backward movement.

Tile is smooth in nature so earthworms cannot move as the setae will not get sufficient surface support to move the body.

If the concentration of H+ ions (protons) were higher inside the mitochondrion than outside when the channel opened, it would lead to the movement of protons from the inside to the outside of the mitochondrion. This movement occurs through a specialized channel known as the ATP synthase or proton pump.

The ATP synthase is a protein complex embedded in the inner mitochondrial membrane. It functions to convert the potential energy stored in the proton gradient into the synthesis of ATP, the energy currency of the cell. When the channel opens, protons flow down their concentration gradient from the higher concentration inside the mitochondrion to the lower concentration outside.

This movement of protons powers the ATP synthase enzyme, causing it to rotate and catalyze the synthesis of ATP from ADP and inorganic phosphate. The higher concentration of H+ ions inside the mitochondrion provides the driving force for ATP synthesis.

Overall, if the concentration of H+ ions is higher inside the mitochondrion than outside when the channel opens, it promotes ATP synthesis by facilitating the movement of protons through the ATP synthase, leading to the production of ATP molecules.

The given statement, "The tissue, at the top of this slide, is simple columnar epithelium and can be found in our intestines" is true.

The epithelial tissue found in our intestines is known as simple columnar epithelium. The simple columnar epithelium has column-shaped cells, which are elongated and taller than their width. These cells have a single nucleus and have a goblet cell that secretes mucus to lubricate the surface. It lines the gastrointestinal tract, uterus, and excretory ducts. Therefore, the given statement is true.The bone shown in the given image is the femur bone. The femur bone is the longest and strongest bone in the human body.

It is located in the thigh region and extends from the hip joint to the knee joint. The femur bone is responsible for supporting the entire weight of the body when a person is standing or walking. It is composed of the head, neck, shaft, and distal ends. The head of the femur bone fits into the acetabulum socket of the hip bone to form the hip joint. The distal end of the femur bone articulates with the tibia bone to form the knee joint.

Therefore, the given bone in the image is the femur bone.

Explanation:

 Contact metamorphism happens when hot magma or lava comes into contact with rocks, causing a small area to change into a metamorphic rock. Contact metamorphism will be present on the outside edges of igneous intrusions.

Heat and/or pressure causes the metamorphism of an igneous rock into a metamorphic rock.

Metamorphic rocks refer to as some other type of rock, but have been substantially changed from their original igneous, sedimentary form. Metamorphic rocks formed when rocks are subjected to high heat, high pressure, hot mineral fluids or, more commonly, some combination of these factors.

Contact metamorphism occurs in rock exposed to high temperature and low pressure, as might happen when hot magma invades into or lava flows over pre-existing protolith. This combination of high temperature and low pressure generates numerous metamorphic facies.

Fingers are made from diploid cells. All of the cells in our body are made from diploid cells except in the reproductive cells which are made from haploid cells.

True: Nutrients and oxygen for deep water animals often come from surface waters through various processes such as upwelling or vertical mixing. This is because the surface waters receive sunlight and are in contact with the atmosphere, allowing for photosynthesis and oxygen exchange.

True: Reef corals are indeed considered polyps. Polyps are small, cylindrical organisms that belong to the phylum Cnidaria, and they are the building blocks of coral reefs. They have a tubular body with a central mouth surrounded by tentacles used for feeding and capturing prey. False: Parapodia in polychaete worms are not used for gas exchange. Parapodia are fleshy appendages found on the sides of each segment of a polychaete worm's body. They are primarily used for locomotion, providing the worm with the ability to crawl or swim. Gas exchange in polychaete worms typically occurs through their thin body wall, which allows for oxygen and carbon dioxide exchange with the surrounding water.
