lungs and capillaries both have porous linings that allow certain substances to move into or out of the structures. Which function do these porous linings most likely serve in living organisms?
A. heat release
B. gas exchange
C. carbohydrate absorption
D. osmotic pressure regulation

Answers

Answer:

B. Gas exchange

Explanation:

because the lungs bring air into your body, it needs a way to transfer the oxygen into your blood stream.

Luckily for us, our lungs have porous linings, which will help the oxygen go directly into our blood stream.

The porous structure of the  blood capillaries and lung tissue allow the them to exchange gas

The porous structure of the lungs allow to exchange gas from the gas in the blood. Blood capillaries are tiny blood vessels in the body.

The gas in the blood was collected from the tissue from the body parts which is made possible because of the porous lining of the blood capillaries.

Therefore, the porous structure of the  blood capillaries and lung tissue allow the them to exchange gas.

All of the following are used by taxonomists to create evolutionary links between species EXCEPT
Select one:
a. analogous structures
b. the fossil record
c. molecular data
d. vestigial structures

Answers

A Analogous structures

The fossil record, molecular data and vestigial structure would help taxonomists to create evolutionary links between species except analogous structures.

What do you mean by fossil record?"A fossil record is a group of fossils which has been analyzed and arranged chronologically and in taxonomic order."What is molecular data?"Molecules such as sequence of DNA used in studies of intra-specific variation and studies of similarity among species."What is vestigial structure?"Structures that have no apparent function and appear to be residual parts from a past ancestor are called vestigial structures."What do you mean by taxonomists?"Taxonomists are professionals who specialize in classifying and sorting information based on similar characteristics and patterns."What are analogous structures?The structure of different species performing similar function but are from different origin (do not have common ancestor).

The fossil record, molecular data and vestigial structure all would help taxonomists to find evolutionary links between species where through  analogous structures no links would be created.

Hence, the correct option is a. analogous structures.

Bone and muscles are the connective tissue. Muscle tissue is made up of sheets and fibers of muscle cells woven together.

What is connective tissue?

Animals have a specific tissue called muscle that contracts when activated, applying forces to various body parts.  Together, these fibers and sheets are referred to as muscles, which regulate many other contractile processes as well as an organism's movements.

Depending on their purpose, animals have one of three types of muscle. Despite modest differences, these muscles have a similar structure and function. Muscle tissue has a unified function and is frequently joined by the same nerve bundles.

Therefore, Bone and muscles are the connective tissue. Muscle tissue is made up of sheets and fibers of muscle cells woven together.

all plant bodies(root,stem and leaf) are externally covered by epidermis but why woody plant is covered by barks​

Answers

Answer:

Bark comprises all the tissues surrounding the xylem in woody plants. Broadly, bark includes an inner and mostly living region and an outer, dead one. Of all plant structures, bark has the most complex anatomical structure and ontogenetic origin involving two (and often three) different meristems.

As to why, the bark adds layers to the inside ring of the vascular cambium, the outside is pushed outward. The cells die off, and the fibrous matrix of cellulose and lignin molecules remain. This hard structure forms the bark, and protects the tree or plant from many forms of damage.

Answers

Answer:

Energy

Explanation:

Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy (ΔH < 0). In the lab, exothermic reactions produce heat or may even be explosive.
