A scientist discovers several new prokaryotic organisms near a deep seafloor vent. Which best describes the general characteristics of these organisms?
A.
colonial, autotrophic
B.
multicellular, heterotrophic
C.
single-celled, autotrophic
D.
multicellular, autotrophic
Answer:
a,
Explanation:
The general characteristic of the new prokaryotic organisms is single-celled, autotrophic. Therefore, the correct statement is option C.
What are prokaryotic organisms?Prokaryotic organisms are unicellular organisms that lack a nucleus and other membrane-bound organelles. They can be either autotrophic or heterotrophic.
Deep seafloor vents are chemosynthetic organisms, which produce organic molecules using energy from chemical reactions. Prokaryotic organisms include bacteria and archaea and are the most common types of organisms found in deep-sea vents, and many of these are chemosynthetic and autotrophic.
The new prokaryotic organisms discovered near a deep seafloor vent are single-celled and autotrophic which can produce their food through chemosynthesis.
Therefore, new prokaryotic organisms near a deep seafloor vent are that they are single-celled and autotrophic.

The main difference between the water cycle and the other chemical cycles is that water
never changes its structural form (H2O) .
is much slower than the other cycles.
creates completely new substances.
is made from matter that has been here since the world was formed.
Answer:
The answer is A.
Explanation:
Other cycles change their structural form often, but water does not change it's structural form in the water cycle, which is H2O so that is one main difference between the water cycle and oither checmical cycles. So, your answer is A.
The main difference between the water cycle and the other chemical cycles is that water never changes its structural form (H2O). Thus, the correct option for this question is A.
What is the water cycle?The water cycle may be defined as a type of biogeochemical cycle that significantly involves the gradual and continuous movement of water and its derivative products within the Earth and atmosphere.
The water cycle remarkably consists of three major processes. They are as follows:
Evaporation: a process through which a liquid converts into gas.Condensation: a process through which gas converts into liquid.Precipitation: a process through which liquid water falls on the earth's surface.The most important concept of the water cycle is that the structural form of water remains constant and the same throughout the process. This property of water differs from other chemical cycles because such cycles involve the alteration in their fundamental component.
Therefore, water never changes its structural form (H2O) is the main difference between the water cycle and the other chemical cycles. Thus, the correct option for this question is A.

The cell membrane serves many functions. One of the cell membranes functions is to help the cell maintain homeostasis. How does the cell membrane do that ?
Answer:
The cell membrane help to maintaining homeostasis by regulating the flow of substances through it and by recognizing potentially harmful agents to the cell.
Explanation:
Cellular membrane is constituted by a lipidic bilayer, whose characteristics allow it to behave as a semi-permeable membrane to the passage of substances.
The selective permeability of the membrane makes it possible to regulate the passage of water, molecules and ions through it into the cell and from there into the extracellular space, a characteristic that allows the maintenance of homeostasis.
Additionally, the cell surface can identify foreign and potentially harmful agents, which can affect the internal balance, preventing in most cases their passage into the cell.
Which of the following best describes the effect of a greater number of cysteine amino acids on the stability of the proteins
Answer:
The correct answer is -
The change leads to increased protein stability because of an increased number of S-S bonds in the tertiary structure of the proteins.
Explanation:
Cysteine is a special amino acid due to having a free thiol group that can react and forms a sulfur-sulfur bond with another thiol of another cysteine in a protein structure.
These disulfide bonds can stabilize proteins if formed properly and promote stability to the tertiary structure of the proteins. The more the cysteine, the greater the number of thiols, and the greater the s-s bond in the proteins and more stability to the protein.
How is homeostasis achieved?
A: Cells maintain internal stability
Homeostasis is achieved once a continuous state of steady internal, physical, and chemical conditions are maintained.
Answer:
A. Cells maintain internal stability

why are index fossils useful to geologist
a.they tell the relative age of the rock in which they occur
b. they tell the ages of many different rock layers
c.they tell the age of the rock at one location only
d. they tell the absolute age of the rock in which they occur
Answer:
Explanation:
Index fossils (also known as guide fossils or indicator fossils) are fossils used to define and identify geologic periods (or faunal stages). Index fossils must have a short vertical range, wide geographic distribution and rapid evolutionary trends.
Index fossil, any animal or plant preserved in the rock record of the Earth that is characteristic of a particular span of geologic time or environment. A useful index fossil must be distinctive or easily recognizable, abundant, and have a wide geographic distribution and a short range through time. Index fossils are the basis for defining boundaries in the geologic time scale and for the correlation of strata. In marine strata, index fossils that are commonly used include the single-celled Protista with hard body parts and larger forms such as ammonoids. In terrestrial sediments of the Cenozoic Era, which began about 65.5 million years ago, mammals are widely used to date deposits. All of these animal forms have hard body parts, such as shells, bones, and teeth, and evolved rapidly.

Why flower produces only a small amount of nectar (food for insects) at a time
Answer:
Nectaries are usually located at the base of the flower stamens, which draw animal visitors into contact with the pollen to be transferred. Most flowers secrete only relatively small amounts of nectar, which encourages cross-pollination, since animals must visit several flowers in order to receive a full meal.
