Very long and large organic molecules called what are made of small units called what.

Answers

Answer 1

Answer: A macromolecule is a very large molecule important to biological processes, such as a protein or nucleic acid. It is composed of thousands of covalently bonded atoms. Many macromolecules are polymers of smaller molecules called monomers.

The _______ the time period during which a species lived and the _______ the distribution of its fossils, the better an index fossil the species is. shorter; narrower shorter; wider longer; narrower longer; wider

Answers

The index fossils have a shorter time period and wider geographical distribution of fossils.

What is an Index fossils?

An Index fossils refers to class of fossils that had a wide geographical distribution and they were present for a comparatively shorter period of time.

They helped in the construction of geological periods that are commonly used today.

Thus, the index fossils have a shorter time period and wider geographical distribution of fossils.

Therefore. the Option B is correct.

Answers

Photosynthesis is carried out in the chloroplasts which contain the green pigment chlorophyll. Chlorophyll is what gives plants their characteristic color and it works by capturing the energy that is in the sunlight that strikes the plant. Photosynthesis is important to life on Earth because grass uses photosnthesis to produce glucose, which is used within the grass for growth. Subsequently, organisms that consume the grass obtain energy and so on. Therefore, photosynthesis is the process through which energy enters an ecosystem.

the answer is chlorophyll

Which of these make up the vascular tissue?

Answers

Vascular tissue consists of xylem and phloem.

Explanation:

Vascular tissue could be a advanced conducting tissue, shaped of over one cell kind, found in vascular plants. the first parts of plant tissue are the vascular tissue and vascular tissue. These 2 tissues transport fluid and nutrients internally. The cells in plant tissue are generally long and slender

Phloem make up the vascular tissue. It helps in the transportation of the food prepared by the leaves of the plant.

Further Explanation:

Phloem is made up of vascular or livingtissue. It uses the turgor pressure that helps in the transportation of sugar to each part of the plants. It also supports the transportation of proteins and m RNA (messenger ribonucleic acid) to each region of the plants.

Phloem is composed of certain specialized cellssuch as sieve tubes, phloem fibers, companion cells and parenchyma cells. The phloem is divided into two types namely; primary phloem and secondary phloem. The primary phloem consists of the apical meristem. It is a region of new cell formation. It lies on the tip of root and shoot. It is further divided into two types; protophloem or metaphloem. The cell of Protophloem mature before elongation, whereas metaphloem mature after cell elongation. Secondary phloem resides in the plant that have a cambium.
