The ribs are curved, flat bones which form the majority of the thoracic cavity. They provide protection to the internal thoracic organs and twelve pairs of ribs articulate with the vertebral column.
what is vertebral column?The vertebral column or spine or backbone, is a flexible column forms a part of the axial skeleton which is a characteristic feature of the vertebrates, placed dorsally and composed of 26 segmented units, called vertebrae.
It forms the central axis of the body skeleton and emerges from the neck at the base of the skull and extends upto the tail.
The vertebral column of human consists of 33 bones at birth, the lower 9 bones fuse into two separate bones and the upper 24 bones are separated and articulated by intervertebral disc during adult stage. T
The number of bones in the vertebral column is 26 where 7 are cervical vertebrae, 12 thoracic vertebrae, 5 lumbar, 1 sacral (fused) and 1 coccygeal (fused) vertebrae. T

A team of biologists discovers a new ecosystem with lush vegetation but no bodies of water nearby. They monitor the ecosystem for a year, recording daily rainfall during that time. Which statement best explains the lack of bodies of water in this ecosystem?
The water is permanently held in clouds.
Water stays predominantly in groundwater sources.
Evaporation transfers rainwater into the atmosphere.
Water is frozen underground instead of flowing on the surface.
The statement that best reveals the scarcity of bodies of water in this ecosystem is as follows:
Evaporation transfers rainwater into the atmosphere.Thus, the correct option for this question is C.
What is an Ecosystem?An ecosystem may be defined as a place or an area where individuals of different species live together and interact with one another for the purpose of food, shelter, and space.
A newly formed ecosystem that a team of biologists identified significantly illustrates the scarcity of water or no bodies of water near its geographical locations. The most prominent and valid reason for this claim is the rate of evaporation that converts rainwater into vapor form in the atmosphere.
The amount of water in any ecosystem may significantly be found less or completely absent when the rate of evaporation is significantly high in that ecosystem. It is based on the fact of temperature.
Therefore, the correct option for this question is C.

severe anemia may trigger an adaptive conversion of:
Severe anemia may trigger an adaptive conversion of yellow bone marrow to red bone marrow.
Anaemia is defined as the decrease or the reduction of the oxygen carrying content of the blood which are the red blood cells.
These red blood cells and other blood cells which include the white blood cells and the platelets are produced in the body by the bone marrows by a process called haemopoiesis.
The bone marrow is divided into two:
yellow bone marrow andred bone marrow.The red bone marrow is made up of stem cells which can be converted to red cells when the need arises while yellow bone marrow is made up of fat.
During health conditions such as anaemia, there is increase in the need of red blood cells by the body.
There is usually the conversation of yellow bone marrow to red bone marrow to compensate for the increased demand of red blood cells.
This conversation is called an adaptive conversation.
Therefore,Severe anemia may trigger an adaptive conversion of yellow bone marrow to red bone marrow.

What would happen if a similar diffusion/osmosis experiment were performed with plant cells instead of animal cells? would plant cells behave in the same manner?
Answer: because plant and animal cells can tolerate different concentrations of water.
Explanation:
Image result for What would happen if a similar diffusion/osmosis experiment were performed with plant cells instead of animal cells? would plant cells behave in the same manner?
Osmosis affects plant and animal cells differently because plant and animal cells can tolerate different concentrations of water. ... However, plant cells need more water than animal cells, and will not burst in a hypotonic solution due to their thick cell walls; hypotonic solutions are ideal for plant cells.
When diffusion and osmosis experiments are performed on a plant cell, the plant cell will expand because it has a rigid cell wall, which prevents it from bursting.
What are osmosis and diffusion?Osmosis is the process when molecules move from a lower concentration area to a higher concentration area.
Diffusion is the process, in which the molecules move from higher concentration to lower concentration.
When osmosis happens to the animal cells, it will fully fill and burst.
But, it will not happen in the plant cell, because it contains a cell wall.
Thus, When diffusion and osmosis experiments are performed on a plant cell, the plant cell will expand because it has a rigid cell wall, which prevents it from bursting.

An organism has brown fur, eats nuts and berries, and hibernates in the winter. What biome is this organism likely a part of? Explain your thinking.
Answer:
Forest.
Explanation:
Berries and nuts are typically fruits and products of trees, and there must be plentiful amount in which to have a population (though it states only an organism, but it can be assumed). Brown fur is typically camo against a brownish background, which can be reflected essentially through bark & wood of trees.
*Most likely the given organism is a squirrel, which typically prefer forest or habitats with trees or tree-like objects.

as you know squirrels have brown fur and eats nuts and fruits but many squirrels does not hibarnate in winter so the squirrel is not actual answer so chipmunks is the species of animals which have brown fur and eats nuts and fruits and hibarnates in winter.

A typical eukaryotic cell has enough available ATP to meet its needs for about 30 seconds. What is likely to happen to an individual when they exhaust their ATP supply? ATP will be transported into the cells from the circulatory system. Catabolic processes will be activated to generate additional ATP. The athlete will have to sit down and rest. Anabolic processes will be activated to produce new mitochondria.
In the case of given scenario, the catabolic processes will be activated to generate additional ATP. The correct option is B.
What are catabolic processes?Catabolic processes are the set of enzyme-catalyzed responses that disintegrate or degrade fairly large molecules in living cells.
Part of the chemical energy emitted during catabolic processes is conserved as energy-rich compounds such as adenosine triphosphate [ATP].
Thus, the correct option is B.
