Answer:
Structure that organizes motion of chromosomes. Cytoplasm. Material in cell; contains chemical wealth: sugars, amino acids, and proteins a cell uses to carry out everyday activites. Vacuole. Saclike structure (large in animal cell); stores water, salts, carbs, and proteins. Plays a role in disposing waste.
Explanation:
There are various structures that are found present in a cell. And these structures have peculiar functions they carry out in the cell. Chromosomes are found in the nucleus of a cell. During cell division there is the needed movement of the chromosomes.
The structure that organizes motion of the chromosomes is the centriole
The centriole is a structure found in the animal cells near the nucleus that aid in the movement of chromosomes through the action of the microtubule and spindle fibres. They help to assemble these microtubules and spindle fibres to aid movement of chromosomes.Learn more: https://brainly.com/question/24552946

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.

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.

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.
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.

what is carrying capacity? what type of population growth does it affect?
Carrying capacity is referred to a population size of species in a particular habitat. In an ecosystem, the population of a species will increase till it reaches its carrying capacity. Then the population size remains relatively equal.
What are the types of carrying capacity?Carrying capacity is the maximum limit till that the ecosystem can support the existence of the population.
There are four categories of carrying capacity, namely:
Physical.Ecological.Economic.Social.A specific environment's carrying capacity is the maximum population size that it can support.
The carrying capacity modifies the growth rate by slowing it when resources become scarce and stopping growth once it is reached.
Thus, it can be concluded that the carrying capacity is the average population size of species in a particular habitat which slows and stops the growth rate on reaching it.
