Osteoclasts are responsible for aged bone resorption and osteoblasts are responsible for new bone formation.
What are the functions of osteoclasts?Osteoclasts are the cells that degrade bone to initiate normal bone remodeling and mediate bone loss in pathologic conditions by increasing their resorptive activity.
The primary role of osteoblasts is to lay down new bone during skeletal development and remodelling. Throughout this process osteoblasts directly interact with other cell types within bone, including osteocytes and haematopoietic stem cells.
The area of the osteoclast next to bone forms a “ruffled border” consisting of multiple infoldings of the osteoclast cell membrane. It secretes acid and proteases across the ruffled border.

How is burning fossil fuels linked to global warming?
Answer:
When we burn oil, coal, and gas, we don't just meet our energy needs—we drive the current global warming crisis as well. Fossil fuels produce large quantities of carbon dioxide when burned. Carbon emissions trap heat in the atmosphere and lead to climate change

the diagram below represents a portion of a cell membrane. The arrow indicates that the cell membrane is carrying out the process of...
Answer:
In the portion of the cell membrane shown in the diagram, the arrow indicates the process of active transport.
Explanation:
Active transport is one of the mechanisms of transmembrane transport, which involves the use of energy. The diagram (see image) shows the hydrogen (H⁺) output from the cytoplasm to the extracellular space, through an H⁺ pump —consuming ATP— which represents an active transport process.
The hydrophobic nature of the cell membrane prevents the free passage of hydrosoluble elements or ions, as H⁺, so they require the use of active transport to pass through it.
The other options presented are not correct, because

The most primitive annelids have a pair of ventral nerve cords joined by transverse connectives; the most advanced forms have the cords fused to form a single cord. A ganglionic swelling of the cord is found in each body segment, with the most anterior ganglion, the subpharyngeal ganglion, being the most prominent.

Important Ions move from low to high concentration while using a membrane protein. Which of the following is true? Question 5 options:
A. It's moving down the concentration gradient.
B. Energy is needed to make this happen
C. It's facilitated diffusion.
D. It's osmosis.
Answer:
A) it is moving down the concentration gradient
Explanation:
Brownian motion will cause the molecules (or ions) to spread/diffuse from where they are more concentrated to where they are less concentrated until they are equally distributed in that space (Figure). When molecules move in this way, they are said to move down their concentration gradient.

Describe what needs to occur in order for a metamorphic rock to form.
If your not gonna put a HELPFUL ANSWER, please do not answer, thanks.
Answer:
Any sort of prexisting rock whether sedimentary, igneous, or even metamorphic rock must change under extreme conditions like extreme heat or pressure.
Explanation:
An igneous rock is a rock that has been created via cooling of magma.
A sedimentary rock is formed from sediments, whether they be natural like seashells, or other pieces of older rocks that have worn away. usually formed under pressure.
A metamorphic rock is a rock that's changed, because it was put under extreme pressure or exposed to extreme heat.
Think of the part morphic in the word metamorphic-it literally means that it morphed or that it changed dramatically.
There are two ways for a rock to become metamorphic under extreme pressure or extreme heat. and there are two types of metamorphic rocks, contact metamorphism and regional metamorphism.
Those mean pretty much exactly what they say.

Cells in every part of an earthworm's body need oxygen. Which TWO statements explain how an earthworm's organ systems help provide its cells with oxygen?
A. The nervous system removes oxygen from the body
B the circulatory system carries oxygen to different parts of the body.
C the respite system brings oxygen into the body
D the digestive system delivers oxygen to the blood.
The circulatory system carries oxygen to different parts of the body, and the respiratory system brings oxygen into the body are the two statements which explain how an earthworm's organ systems help provide its cells with oxygen. Therefore, the correct option is B and C.
What are organ systems?The term organ system refers to the group of organs that work together to perform one or more functions of the body.
Earthworms have a closed circulatory system, which means that blood flows within vessels. The circulatory system carries oxygen from the respiratory surface (the skin) to different parts of the body, where it can be used by the cells for respiration.
Earthworms breathe through their skin, which is kept moist by mucus. Oxygen diffuses across the moist skin and into the circulatory system, where it is carried to the cells.
Both A and D are incorrect because both of these systems are not involved in carrying or delivering oxygen to or from the blood. Therefore, the correct option is B and C.

1. What does photosynthesis do for the plant?
2. What does cellular respiration do for the plant?
Answer:
Explanation:
1.Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.
2.The process of cellular respiration allows plants to break down glucose into ATP. The ATP provides the energy they need to carry out various functions. Although plants use photosynthesis to produce glucose, they use cellular respiration to release energy from the glucose

What do you know about deserts, grasslands, or tundra biomes?
Answer:
this is what i do when i bored :P
Explanation:
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to the processes of denudation. Grasslands are areas where the vegetation is dominated by grasses. However, sedge and rush can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. In physical geography, tundra is a type of biome where the tree growth is hindered by low temperatures and short growing seasons. The term tundra comes through Russian тундра from the Kildin Sámi word тӯндар meaning "uplands", "treeless mountain tract".
Why do animal cells burst when they are hypotonic?
Answer:
When animal cells are hypotonic means, the cell has absorbed too much water through the membrane. Therefore, the osmotic pressure is very high. Consequently,they deform and could eventually burst.
