Well, both are caused by rain water, sunlight, and they are connected by the roots.

Hope this gave you an idea! :) Please mark me Brainiest! :)

During the second half of glycolysis, what occurs?

victus00 [196]

Answer:

During the second half of glycolysis , ATP is made occurs .

Explanation:

Glycolysis -

In the first pathway of Glycolysis in the cytoplasm , it breakdowns the glucose to release energy .

Glycolysis has two parts -

In the first part , the six carbon moiety glucose break down to two three - carbon sugar moieties , in this process two molecule of ATP are invested .

In the second part , glycolysis extracts ATP and electron of high energy from the hydrogen atoms and gets attached to the NAD⁺ , in this process four ATP molecules are formed by the substrate phosphorylation .

Hence,

In the net process , Two molecules of ATP are formed .

Answer:

It is required that the seed region of the processed dsRNA molecule bind to the mRNA of mex-3 in order to inhibit its translation

Explanation:

Double-stranded RNAs are small interfering non-coding RNAs (about 20 nucleotides in length) that, after processing, can bind by complementary base pairing to RNAs and thus inhibit protein translation by a mechanism referred to as 'RNA interference' (RNAi). The base pairing is not always perfect; however, the guide strands of dsRNAs can conserve their ability to inhibit the translation if the complementarity is enough good to match target RNA sequences. The critical region in the dsRNA that is required to bind target RNAs is known as seed region, and consists of 6 to 8 nucleotides in length.

Answer:

The following images of different types of bacteria are attached here-

1- Single round bacterium- Cocci

2- Single rod-shaped bacterium- Bacilli

3- Cluster of round bacteria - Staphylococci

4- String of rod-shaped bacteria- Streptobacillus

5- Comma-shaped bacterium- Vibrio

6- Corkscrew-shaped bacterium- Spirillium

Explanation:

1- Single round bacterium- Cocci -Any bacterium or archaeon that has a circular, ovoid, or usually round shape is a coccus (plural cocci). Cocci may develop in pairs, chains, or clusters during cell division, depending on their orientation and attachment. Many cocci bacteria do not have flagella and are non-motile, in contrast to many bacilli-shaped bacteria.

2- Single rod-shaped bacterium- Bacilli -A rod-shape bacterium or archaeon is a bacillus (plural bacilli), or bacilliform bacterium. In several different taxonomic classes, bacilli are found. Bacilli typically divide and are solitary in the same plane, but can combine to form diplobacilli, streptobacilli, and palisades.[2]

Diplobacilli: Two bacilli with each other arranged side by side.

Streptobacilli: Arranged bacilli in chains.

Coccobacillus: Coccus-like and oval (circular-shaped bacterium).

3- Cluster of round bacteria - Staphylococci - In the family Staphylococcaceae from the order Bacillales, Staphylococcus is a genus of Gram-positive bacteria. They appear spherical (cocci) under the microscope, and form into grape-like clusters. The species Staphylococcus are facultative anaerobic organisms (both aerobically and anaerobically capable of growth)

4- String of rod-shaped bacteria- Streptobacillus -Streptobacillus is a genus of fastidious gram-negative microaerophilic bacteria, an uncommon disease that develops in culture as rods in chains.t and can be caused by two forms of bacteria, Spirillum minus and Streptobacillus moniliformis.

5- Comma-shaped bacterium- Vibrio -Vibrio is a genus of Gram-negative bacteria with a curved-rod (comma) shape, which can cause foodborne infection in several animals, typically associated with consuming undercooked seafood. Vibrio species, usually found in salt water, are optional anaerobes that test positive for oxidase and do not form spores.

6- Corkscrew-shaped bacterium- Spirillium -Spirillum, a genus of spiral-shaped bacteria of the Spirillaceae family, aquatic with the exception of one species (S. minus) causing a form of human rat-bite fever. For any of the corkscrew-like animals, the name spirillum is used commonly.

Microbiologically, Spirillum is characterized as a gram-negative, motile helical cell with whiplike flagella tufts at each end.

hence, the images of the different bacteria are attached below-:

Benzopyrene is a compound found in cigarettes that binds to the base guanine in DNA. This distorts the DNA double helix and caus

dlinn [17]

Answer:

Explanation:

When a substance has the capacity to disrupts the genetic compositions (DNA) of the organisms, to the extent that it makes the particular organism genetic materials prone to genetic mutation,( random changes in the genetic composition) such group of substances are called Mutagens.

ionizing radiation,radioactive decay are some examples of of physical mutagens, while biological mutagens examples include viruses and bacterial. Chemical mutagens are Benzene compounds,bromine,aromatic amines,sodium Azide.

They exerts their negative effects

by disrupting gene expression sequence of transcription, translation, or changed the nucleotides sequence of the DNA leading to deletion, addition, subtraction of genetic bases.Some may make chromosomes to be unstable, disrupting the structure

Although some mutagens can cause cancer, that is they are mutagens. not all mutagens carcinogenic.This is because the Mutagenic effects depends on the metabolites present in the cells of the organisms.
