What are microorganisms ?A living thing that can only be observed under a microscope. Protozoa, algae, fungus, and bacteria are all examples of microorganisms. Viruses are occasionally categorised as microbes even though they are not thought of as living things.
There are seven different categories of microorganisms: multicellular animal parasites, bacteria, archaea, protozoa, algae, fungi, and viruses ( helminths ).For instance, each human body contains 10 bacteria for every human cell, and these microbes support immune system development, aid in digestion, make vitamin K, and detoxify toxic substances. Of course, bacteria are necessary for the production of many of the items we eat, like bread, cheese, and wine.Learn more about Microorganisms here:

Alex poured some pond water into three beakers. She then put waterweed into each beaker. She put the beakers in different places.
b. In the school pond there were lots of water lilies with large leaves covering the surface. There were not many plants growing below the surface. Suggest a reason for this.
Answer:
because the water lillieswere covering the pond so less light was entering
Answer:
The reason for this because no plant grows in no light area.
Explanation:
In the second answer, we can see that the pond is covered with water lilies which have larger leaves covering the large surface area of water, not allowing sunlight to pass through it. Sunlight is necessary to carryout photosynthesis, which means plant don't grow in no light condition. Hence, no plant grows in no light area.

In dna sequencing, how does the addition of dideoxynucleoside triphosphates (ddntps) terminate the synthesis of new dna? \
ddNTPs have a hydrogen at 3' position which terminates synthesis of DNA.
ddNTPs is the abbreviated form for dideoxynucleotides triphosphates. They are known as chain elongating inhibitors. The Sanger method is a sequencing technique that is used to increase the number of DNA copies. The DNA synthesis requires magnesium ions, a single-stranded DNA template, oligonucleotide primer, and nucleotide precursors like dATP, dGTP, dTTP, and dCTP. Also, DNA polymerase is required which is an essential component for DNA synthesis.
The Sanger sequencing method is a significant process evident by its use in Human Genome Project which helped scientists in sequencing the human genome. The small sequenced fragments are joined together to form large regions subsequently forming chromosomes.

True. People with difficulty seeing objects at a distance are said to have myopia.
What is myopia?Nearsightedness (myopia) is a common vision issue in which you can see items close to you well but objects farther away are indistinct. It happens when the shape of your eye causes light rays to bend (refract) wrongly, focusing images in front of your retina rather than on your retina.
Symptoms of nearsightedness may include:
Blurry vision when looking at faraway objectsThe necessity to squint or partially close one's eyelids in order to see clearlyEye strain causes headachesDifficulty seeing while driving, especially at night (night myopia)A refractive error is what leads to nearsightedness. When your eye doesn't focus light properly, a refractive error happens. When you are nearsighted, your eye instead focuses light in front of your retina than onto it.

The smooth endoplasmic reticulum manufactures lipids and carbohydrates.
The Rough endoplasmic reticulum assists in the synthesis of proteins and send them to the Golgi bodies.
What is the endoplasmic reticulum?
The endoplasmic reticulum (ER) is a continuous membrane structure that divides into flattened sacs in the cytoplasm of eukaryotic cells. It has a variety of roles but is notably crucial for protein synthesis, folding, modification, and transport.
Rough endoplasmic reticulum: Its name comes from the rough texture of its outer (cytoplasmic) surface, which is caused by the presence of ribosomes there. Rough ER is located next to the cell nucleus, and the nuclear envelope's outer membrane is continuous with its membrane.Smooth endoplasmic reticulum: It is distinct from ribosomes and has a different set of functions. The synthesis of lipids, including as cholesterol and phospholipids, which are needed to create new cellular membranes, is carried out by the smooth ER. Smooth ER is crucial for the synthesis of steroid hormones from cholesterol in certain cell types.

The repressor is a type of regulator protein that binds to a region of DNA in the promoter of a gene called the operator and prevents transcription from taking place.
In the field of science, a regulator protein can be described as a kind of protein that affects the transcription of a gene by having an influence on particular DNA sites. The rate of synthesis of various proteins is controlled by the regulator proteins.
A repressor is a kind of regulator protein that prevents the transcription of a particular gene. When the rate of a protein in the body has reached normal, the transcription of the protein needs to be stopped in order for more protein of that kind to be formed.

Embryonic stem cells give rise to all cell types in the developing embryo. would you expect the interphase period of a stem cell to longer, shorter, or the same as compared to non-stem cells?
The interphase in embryonic stem cells is shorter as they are rapidly dividing.
Pluripotent stem cells, called embryonic stem cells (ESCs), are generated from the inner cell mass of the blastocyst, an early-stage preimplantation embryo. Four to five days after fertilization, the human embryo reaches the blastocyst stage, which consists of 50-150 cells. The blastocyst is destroyed when the inner cell mass (germinal cells) are separated by immuno surgery, raising moral questions as to whether the pre-implantation embryo follows the same moral standards as the post-implantation development. Similar to adult stem cells, these are stem cells supplied by a healthy, fully developed human being. They were not collected or implanted using embryos or fetuses. Scientists believe that stem cells can be used to treat and understand disease because they can differentiate into different cell types.Therefore, embryonic stem cells will have shorter interphase.

Which neurotransmitter stimulates skeletal muscle cells to contract but slows contractions of the heart?.
The neurotransmitter that stimulates skeletal muscle cells to contract but slows contractions of the heart is acetylcholine.
Neurotransmitters are chemical messengers that are produced inside the neuron and play a role in the nervous system to transmit messages from nerve cells to the targetted cells.
Acetylcholine is synthesized from acetyl-CoA and choline by the cholinergic neurons. Acetylcholine stimulates muscle cell contraction by binding to its receptors on muscle fibers which results in the opening of the sodium channels so that sodium ions can enter the cell which eventually results in contraction.
The muscarinic M2 receptors present in the heart slow down the heart rate by decreasing the rate of depolarization. Acetylcholine binds to these receptors and activates them which results in decreased contractions of the heart.

The tails of the core histone proteins can be chemically modified by the covalent addition of what type of chemical group?.
Answer:
The tails of the core of proteins can be chemically modified by the covalent addition of acetyl, methyl and phosphate.
Histone and DNA have complex interface. Every nucleosome has 142 hydrogen bonds have seen between histone core as well as the DNA. An amino acid backbone of both the histones as well as the phosphodiester backbone of the whole DNA is where about half of these linkages are formed. Condensation of chromatin could be facilitated by methylating the histone tails inside the chromatin. DNA can be accessed for transcription by acetylation of histone tails within chromatin. Certain types of chromatin change could be transmitted to the next cell generations. The DNA is coiled more securely all around histone cores when the histone tails are deacetylated, which makes it more difficult for transcriptional to attach to the DNA. This process, termed as gene silencing, results in lower levels of gene expression.
