Grass hopers move then you think when they move they adapt to the new envirment.

Snails and slugs are commonly known as gastropods. In course of several million years they have colonized almost on every habitat of the Earth. The gastropods had to overcome several evolutionary outcomes in all adaptations. Gastropods can live in diverse habitats as the different species survive on different modes of nutrition. The snails secrete a fluid through which they can move on all types of surfaces. The origin of the colonization of gastropods or snails to terrestrial habitats from aquatic is believed to have taken place via estuaries or semi-terrestrial habitats such as mangroves.

Some birds like Parus major carry snails in their plumage which suggests that some gastropods were transported from one habitat to another by unintentional ways.

Which organism pictures is not an autotroph

professor190 [17]

An autotroph is an organism capable photosynthesis or chemosynthesis through reducing carbon dioxide, fats, sugars and/or proteins in a repetitive cycle of energy production and use to support its life. these include all plants, algae and certain bacterium.

its counterpart is the heterotroph which is reliant on outside sources for their means of energy. aka tertiary consumer: animals, fungi and certain bacterium

False politics & economics have to do with government not the environment but that’s pretty self explanatory

Axons of the nervous system are described as afferent and efferent according to the direction in which they carry information. W

Ahat [919]

Answer:

The correct option is b) motor output of the spinal cord

Explanation:

Motor neurons, also called afferent neurons, drive impulses from the brain and spinal cord to the receptors (eg, muscles). They are the motor output component of the spinal cord.

The spinal cord is a cord of nerve tissue that runs inside the spine. It conducts the nerve impulses that arrive from the receptors to the brain, and the responses with the motor orders from the brain to the effector organs. Thus, the brain receives the information and can develop an order that modifies the reflex response given by the spinal cord. A spinal nerve has two nerve roots: a motor and a sensory root. The motor root has nerve fibers that carry signals from the spinal cord, to the muscles to stimulate contraction and produce muscle movements, the fibers are efferent as they leave the medulla to the periphery through the anterior roots of the spinal nerves.

Which pair is incorrectly matching polymer-monomer? nucleic acids - nucleotides proteins - amino acids lipids - monosaccharides

Andrew [12]

The pair that incorrectly matches polymer-monomer is lipids-monosaccharides (option C).

<h3>What is a monomer?</h3>

A monomer is a small molecule which can be covalently bonded to other monomers to form a polymer.

A polymer, on the other hand, is a large molecule made up of a chain of many monomeric units, formed by chemically bonding together.

The following are the monomer-polymer combination we have in nature;

Carbohydrates - simple sugar/monosaccharide
Protein - amino acid
Lipids - fatty acid
Nucleic acid - nucleotide

Therefore, the pair that incorrectly matches polymer-monomer is lipids-monosaccharides.

Cancer cells are rogue clones. List and describe three mutations that allow these cells to escape the normal restrictions placed

Amanda [17]

<span>Cells control cell division in order to maintain normal cell function. If something happens to the control of the cell division, the healthy cells will divide uncontrollably. These new cells are cancer cells. </span>
The mutations in three genes are responsible for development of cancers:
1. Mutation in proto-oncogenes. Proto-oncogenes normally signal cells to grow and differentiate. Proto-oncogenes can become oncogenes due to mutations which result in the uncontrollable division of the cells.
2. Mutation in tumor suppressor genes. In normal cells, tumor suppressor genes suppress genes essential for cell cycle and that way they prevent uncontrollable cell division. However, after a mutation in these genes, suppression is lost and the cell may progress to cancer.
3. Mutation in stability genes. In normal cells, they have no role either in cell death or growth, but they control mutation rate. Mutation in stability genes results in situation where all genes, including proto-oncogenes and tumor suppression genes, are more frequently mutated.
