Which enzyme builds the new strand by adding nucleotides?
DNA polymerase is the enzyme that builds a new strand of DNA by adding nucleotides, essentially replicating the DNA for cell division.
Explanation:The enzyme that builds the new strand by adding nucleotides is called DNA polymerase. DNA polymerase synthesizes the new DNA strands from the deoxyribonucleotide triphosphates, which are the building blocks of the DNA molecule. It works by 'reading' the template DNA strand and adding complimentary nucleotides to the growing DNA chain. Essentially, it assembles the DNA strand in a 5' to 3' direction, and in doing so, it helps to replicate the DNA within a cell so that it can be properly divided during cell division.

Briefly describe how the artificial manipulation of plasmids has been used for technological applications
The incorporation of a desired gene from specie to another is achieved using plasmids. We can also say it is used to incorporate a desired gene from particular specie to specie. It is also genetic modification.
The process by which the genetic makeup of an organism is altered is known as genetic modification or genetic engineering.
Examples in this case would be to take a plasmid into antibiotic-resistant bacteria and put it into bacteria that are not resistant to antibiotic, for that reason plasmid insertion into the bacteria that are not resistant to antibiotic would make it to be resistant to antibiotic.
Plasmids are a small molecule of DNA within a cell physically separated from a chromosomal DNA and is able to replicate independently. Plasmids are mostly found in bacteria as small circular, double-stranded DNA, though they are also presents in archaea and eukaryotic organisms.
Plasmids typically can be found in bacterial cells and the gene they carried has advantage towards bacteria (antibiotic resistance). Plasmids are wide in lengths, from about 1000 base pairs to hundred thousands of base pairs.
Plasmids are commonly used by scientists as tools to clone and manipulate genes. Plasmids that are used for these particular purposes are called vectors.

what role do producers and consumers play in the carbon cycle
Answer:
Carbon cycle refers to the biogeochemical cycle by which carbon is exchanged between atmosphere, hydrosphere, geosphere, and biosphere.
Producers like plants use carbon dioxide present in the atmosphere and fix carbon into organic compounds.
Thus, producers fix carbon and make it available in usable forms for consumers.
Consumers use carbon in the form of organic compounds such as glucose and use it for cellular respiration. It releases carbon back into the atmosphere in the form of carbon dioxide.
Thus, consumers return carbon to the atmosphere.

The enzyme lactase breaks the sugar lactose into which compound(s)
The enzyme lactase breaks the sugar lactose into two simple sugars: glucose and galactose. These can be absorbed into the bloodstream and used for energy.
Explanation:The enzyme called lactase plays a vital role in the human digestive system. Specifically, this enzyme breaks down the sugar lactose, which is found in dairy products, into two simpler sugars: glucose and galactose. These simple sugars can then be easily absorbed into the bloodstream and used by the body for energy. For example, if you consume a glass of milk, the lactase enzyme in your small intestine will break the lactose present in the milk down into glucose and galactose.

The enzyme lactase breaks down the sugar lactose into glucose and galactose. These are simpler monosaccharide units, which the body can easily absorb and use for energy.
Explanation:The enzyme lactase breaks down the sugar lactose, a disaccharide, into simpler compounds. These compounds are two monosaccharides, namely glucose and galactose.
This process is vital for the digestion of lactose found in dairy products. If an individual does not produce sufficient lactase, the lactose cannot be broken down properly. This can lead to lactose intolerance, where the undigested lactose causes gastrointestinal symptoms.

Which correctly compares the immunity produced by a vaccine with the immunity produced by injection of antibodies from an external source? Injection of antibodies helps the body develop memory cells, which only produces a temporary immunity, whereas a vaccine can fight infection for years. A vaccine helps the body develop memory cells that make immunity last, whereas injection of antibodies only produces a temporary immunity. Injection of antibodies helps the body develop its own copies of the antibodies so immunity lasts, whereas a vaccine only produces a temporary immunity. A vaccine actively attacks pathogens until it is used up so immunity is temporary, whereas injected antibodies will remain passively in the blood, giving immunity for life.

Type of reproduction takes place in archaebacteria and eubacteria
Answer:
Explanation:
Before knowing their reproduction process let's first understand what is Archaebacteria and Eubacteria.
Archaebacteria- are the oldest living anaerobic organisms on earth. They are unicelled prokaryotes and can live in extreme conditions like inside a volcano vent, hot springs and acidic/alkaline aquatic environment.
Reproduction- They reproduce by asexual reproduction process. Binary fission takes place where the genetic material is duplicated and then the cell wall pinches off from the center and thereof divides into two new daughter cells. They may also divide by fragmentation or budding.
Eubacteria- are the most common organisms found and are known as the true bacteria. They are of single celled prokaryotic origin and have no nucleus, They occur commonly in three shapes i.e. round, rod and spiral.
Reproduction- Mostly, they reproduce by binary fission, where the parent cell divides into two new daughter cells. But some may divide by a process called budding where an outgrowth takes place in the parent cell which gets separated later and the parent cell remains with the new cell formed.

In the process of cellular respiration, there are three main stages. Name the stages AND the beginning and ending products of each stage.
"The three main stages of cellular respiration are:
1. Glycolysis:
- Beginning product: Glucose (C6H12O6)
- Ending products: 2 Pyruvate (C3H4O3) molecules, 2 ATP (Adenosine triphosphate), and 2 NADH (Nicotinamide adenine dinucleotide + hydrogen) molecules.
2. Citric Acid Cycle (also known as Krebs Cycle or TCA Cycle):
- Beginning product: Acetyl CoA (derived from the breakdown of Pyruvate)
- Ending products: 2 ATP, 6 NADH, 2 FADH2 (Flavin adenine dinucleotide + hydrogen), and 2 CO2 (carbon dioxide) molecules.
3. Electron Transport Chain (ETC) and Oxidative Phosphorylation:
- Beginning product: NADH and FADH2 from the previous stages
- Ending products: A large amount of ATP (the exact number can vary, but it is much more than the other stages), water (H2O), and heat.
In summary, the stages and their respective beginning and ending products are as follows:
- Glycolysis: Begins with glucose and ends with pyruvate, ATP, and NADH.
- Citric Acid Cycle: Begins with acetyl CoA and ends with ATP, NADH, FADH2, and CO2.
- Electron Transport Chain and Oxidative Phosphorylation: Begins with NADH and FADH2 and ends with ATP and water.
These stages collectively convert the energy stored in glucose into ATP, which cells can use for various metabolic processes. The overall process of cellular respiration starts with glucose and ends with the production of ATP, CO2, and water."

Freckles are small, spots of a skin pigment called melanin. Most fair-skinned, red-haired people have them. Freckles are controlled primarily by the MC1R gene. Freckles are a dominant trait: parents who have freckles tend to have children with freckles. Bill and Barb both have freckles. Yet of their four children, one child does not have freckles! What must be the genotypes of Bill and Barb?
A) BB and BB
B) BB and Bb
C) Bb and Bb
D) Bb and bb
its d Bb and bb i think sorry if its wrong
Answer:
The correct answer would be C) Bb and Bb.
The phenotype of both parents is a dominant trait. Thus, both of them must contain at least one copy of the dominant allele.
Therefore, the genotype of both parents would be B_.
Case I: When both parents are homozygous dominant, that is, BB. All the offspring would be BB, that is, all have freckles.
Case II: When one parent is homozygous dominant and other is heterozygous, that is. BB and Bb. All the offspring would be either BB or Bb. Thus, all the offspring would have freckles.
Case III: When both the parents are heterozygous dominant, that is, both are Bb. The offspring can have BB, Bb, or bb. One out of four children would have no freckles.
Thus, the correct answer would be C) Bb and Bb.
