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.

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."
Due to a rise in global sea level, a shallow sea covered most of eastern Virginia during the Cretaceous. Virginia had drifted north from the equator and conditions no longer supported the formation of limestone. The tropical climate disappeared, replaced by more temperate conditions. In place of limy sediments, sand and silt were deposited as the sea level receded in the region we now know as the Plateau region. Under these conditions, we would expect to find more fossils of ____________ life forms in this location.

A light microscope that makes the specimen appear light on a dark background is called a(n) _____. compound microscope electron microscope dark-field microscope
The right option is; dark-field microscope
A light microscope that makes the specimen appear light on a dark background is called a dark field microscope.
Dark field microscopes are light microscopes that are used in different ways to clearly view various specimens that are unstained, transparent, and hard to see using a light field unit. Dark field microscopes are very effective because they show the details of unstained and live samples. It is also very simple to use, and inexpensive to set up.
Answer:
The answer is Dark-field microscope.
Explanation:
Dark-field microscope is a microscope that uses a focused beam of very intense light in the form of a hollow cone concentrated on the sample, where the illuminated object disperses the light and thus becomes visible against the dark background behind it, making the transparent portions of the Specimen remain dark, while surfaces and particles look bright. This form of illumination is used to analyze transparent and unpigmented biological elements, invisible with normal illumination, without killing the specimen.

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.

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.

What is the ultimate measure of evolutionary success?
There is only one measure of "evolutionary success": having more offspring. A "useful" trait gets conserved and propagated by the simple virtue of there being more next-generation individuals carrying it and particular genetic feature "encoding" it. That's all there is to it.
One can view this as genes "wishing" to create phenotypic features that would propagate them (as in "Selfish Gene"), or as competition between individuals, or groups, or populations. But those are all metaphors making it easier to understand the same underlying phenomenon: random change and environmental pressure which makes the carrier more or less successful at reproduction.
You will sometimes hear the term "evolutionary successful species" applied to one that spread out of its original niche, or "evolutionary successful adaptation" for one that spread quickly through population (like us or our lactase persistence mutation), but, again, that's the same thing.

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.

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.
All of these are methods by which a cell..
