Cholera-The cholera bacteria is passed through feces (poop). It is spread by eating or drinking food or water contaminated by the feces (poop) of an infected person. This occurs more often in underdeveloped countries lacking proper water supplies and sewage disposal.

You are having a party and the carrot sticks have become limp, what might you do to make the carrots crisp (turgid) again? What is occurring in the cells?

Answers

Answer:

Cut celery can be placed in a bowl of water until crisp. Carrots – cut a little off the bottom of the carrot (not stem end) and place upright in a glass of water until crisp. When the cells are full of water, they grow large and are packed closely together, making the carrot turgid. Conversely, when the cells lose water, they shrink and the carrot shrivels.

How do owls relate to biotechnology?

Answers

Answer:

Owls hunt throughout the night in deserted places such as cemeteries, run-down farms, and other open areas. The diet of many owls consists mainly of rodents and other small animals. Prey is usually eaten whole, but the whole prey is not digested. An owl's digestive tract compresses the undigested portions of the prey, such as fur and bone, into a compact pellet that the owl coughs up and expels through its mouth.

Which represents a short-term storage for carbon?
A Coral reefs formed from calcium carbonate.
B. Coal formed from plants that lived long age
C. Limestone rocks quarried at Earth's surface.
D. Carbohydrates stored in fruits and vegetables.

Answers

Carbohydrates stored in fruits and vegetables represent the short-term storage for carbon.

What is Carbon?

Carbon is a chemical element that is very abundant on the surface of the earth. It exists in nature in its pure forms like Graphite and diamond. It is also required for plants and animals to perform their metabolic activities with the addition of certain other compounds.

Carbon compounds are held for the shortest amount of time in fruits and vegetation.

Therefore, Carbohydrates stored in fruits and vegetables represent the short-term storage for carbon.

Which of the following events occurs directly AFTER a DNA molecule is unzipped?

Answers

Answer:

DNA replication occurs through the help of several enzymes. These enzymes "unzip" DNA molecules by breaking the hydrogen bonds that hold the two strands together. Each strand then serves as a template for a new complementary strand to be created. Complementary bases attach to one another (A-T and C-G).

Explanation:

Which of the following events occurs directly after RNA polymerase recognizes the transcription start site of a gene? the DNA strand begins to unwind, separating the two strands.

Which of the following describes coccolithophores?

a.) a type of algae in which the chlorophyll pigments dominate the visible color that resembles a grassy to apple green

b.) a type of filter feeder that siphons food particles through a mucous membrane filter

c.) a type of single-celled phytoplankton that lives ubiquitously throughout the upper strata of the ocean

Answers

C is the answer because it is a single celled marine flagellate.

Coccolithophores is a type of single-celled phytoplankton that lives ubiquitously throughout the upper strata of the ocean. The correct option is c.

What is phytoplankton?

Phytoplankton are autotrophic members of the plankton community and an important component of ocean and freshwater ecosystems.

Aquatic food webs are built on phytoplankton and algae. Primary consumers such as zooplankton, small fish, and crustaceans consume them. Fish, small sharks, corals, and baleen whales eat the primary consumers.

They provide food for a diverse range of sea creatures in a healthy ecosystem.

Phytoplankton, also known as microalgae, are algae that, like terrestrial plants, contain chlorophyll and require sunlight to live and grow.

A coccolithophore is a type of phytoplankton that is unicellular and eukaryotic.

According to Robert Whittaker's Five Kingdom classification, coccolithophores belong to the kingdom Protista, or the clade Hacrobia, according to the newer biological classification system.

Thus, the correct option is c.

what 2 parts of a chlorplast does photosynthesis take place

Answers

Answer:

The Grana and The Stroma.

Explanation:

I hope this helps u! :D

Answer: Photosynthesis occurs in geranium and stroma parts of chloroplast.

Explanation:

Chloroplast is an organelle covered by double membrane. Inner membrane is folded inside to form lamellae. The lamellae are stacked one above the other to from geranium. There are many grana in a single chloroplast. The remaining matrix consisting of cytoplasm is termed stroma. In the stroma are present other cytoplasmic inclusions like fragments of DNA and ribosome, etc.

Photosynthesis occurs in 2 steps:

1. Hill's reaction or Light reaction: It occurs in presence of light in geranium part of chloroplast.

2. Dark reaction or Blackmann's reaction: It does not require light directly, occurring irrespective of presence or absence of light. However, it is dependent upon the end products of light reaction. it occurs in stroma part of chloroplast.

The answer may be supplemented by viewing the diagram of electron microscopic structure of chloroplast from any book one may have, covering photosynthesis.

Iron reacts with atmospheric oxygen to form iron oxide or ferric oxide. Look at the chemical equation for this reaction: Fe + O2 → Fe2O3

Answers

Answer:

This question is incomplete, the complete part is as follows:

This equation is unbalanced. Which of the following is the correct balanced equation for this reaction?

A. 4Fe + 3O2 → 2Fe2O3

B. 3Fe + 4O2 → 2Fe2O3

C. 2Fe + 4O2 → 3Fe2O3

D. 3Fe + 3O2 → 4Fe2O3

E. 4Fe + 4O2 → 3Fe2O3

The answer is A. 4Fe + 3O2 → 2Fe2O3

Explanation:

This question involved a chemical reaction between iron element (Fe) and atmospheric oxygen (O2) to produce iron oxide. The equation is given as follows:

Fe + O2 → Fe2O3

However, this chemical equation is NOT balanced and not in accordance with the law of conservation of matter. To balance this equation, we have to make sure that the number of atoms of each element on the reactant side is equal to that on the product side. Hence, we use COEFFICIENTS. The balanced equation is given below;

4Fe + 3O2 → 2Fe2O3
