Answer:

3. Rocks erode and sediment is deposited.

4. No sediment is deposited over a long time.

Explanation:

An unconfomity is a break in stratigraphic record of a place usually as a result of non-deposition or erosion.

In a sequence of sedimentary rock strata some surfaces called unconformity surfaces gives clues about the depositional history of a particular place. During an unconfomity, there is usually no sediment deposition and when deposition resumes, the underlying rocks and the new ones will not share the same attribute especially by age. Unconformity can also be as a result of erosion of a sequence.

In the case of non- conformity, a sedimentary rock is deposited above an igneous or sedimentary rock. Option 5 is a simple example of an igneous intrusion called a sill. It is not unconformity.

Which of the following statements is most correct regarding the intracellular chemical signals known as "second messengers"? Sel
Mila [183]

Answer:

Cyclic AMP and calcium may be second messengers.

Explanation:

these are signalling molecules that are located inside the cells,They are releases  when cells   are in contact with  signals from an extracellular molecule. the extracellular molecules that cause the chemical  reaction  in an external environment  in the second messenger are called first messenger.

<u>the basic mechanisms of second messenger involve the binding of ligands to the cell membrane receptors( usually a trans membrane protein).causing   conformational  change in the receptor protein. The latter change affect the structural and functional activities of the receptors protein with a consequent  production of second messenger,</u>

<u />

Response of the cells  to the first messenger my cause different form of cellular reactions; the cells may  undergo depolarization  with influx of out flux of ions, differentiate to specialized cells  or migrate to another location.

Examples of first messenger are hormones and neurotransmitters, while calcium ions, cyclic GMP,AMP, diaclyglycerol are examples of first messengers.

Most first messengers are peptide hormones.Some may be streroid, However, the hydrophilic nature of the peptide hormone restrict their movement, at the cell membranes. Therefore most first messengers made of  peptide  are first converted to second messenger to  bring about their signalling effects.The usually mark the beginning of cascade events by second messengers.

Second messengers are usually classified based on their polarity and molecular form this include the

<u> hydrophobic molecules</u> ;diacyglecerol,phosphatdylinotisols. These diffuse  through the membrane  into intramembrane space of cells cause signalling effects in the cell.

<u>the hydrophiliic  molecul</u>es  are  located in the cystol  of cells. Example are  Cylic AMP. GMP, Calcium,

N02, CO,H2S are <u>polar molecules</u> that easily diffuse into the cells to cause signalling effects, they are the third Classification of second messengers.

Which properties of life are possessed by viruses and green turtles?
Nat2105 [25]

Answer:

The correct answer is : a clear orderly arrangement and ability to reproduce.

Explanation:

Properties of life include different aspects and key characteristic of an organism or life such as, cells or order, adaption, reproduction, homeostasis, growth and development, regulation, sensitivity to a stimuli and other.

In green turtles and virus both shows reproducing ability and clear orderly arrangement as properties of life. They both can produce their offspring and increase their numbers.

Thus, the correct answer is : a clear orderly arrangement and ability to reproduce.

Which of these statements best describes evolution? a. the progression through time from simple to complex organisms. b. a proce
guapka [62]
The answer is <span> b. a process of change through time.

Evolution is a process of change through time.  It does not result in progress. Natural selection, one of the mechanisms of evolution, can result in progress and </span>cause some organisms to develop characteristics they need. But generally speaking, natural selection is not the only mechanism of evolution. Other evolutionary mechanisms, such as genetic drift, mutations, migration, can in some cases have a harmful outcome.
