Answer:
A scanning transmission electron microscope has achieved better than 50 pm resolution in annular dark-field imaging mode and magnifications of up to about 10,000,000× whereas most light microscopes are limited by diffraction to about 200 nm resolution and useful magnifications below 2000×.
In addition to oxygen, which gases make up the largest percentage of Earth's atmosphere?
Answer: Nitrogen and oxygen are by far the most common; dry air is composed of about 78% nitrogen (N2) and about 21% oxygen (O2). Argon, carbon dioxide (CO2), and many other gases are also present in much lower amounts; each makes up less than 1% of the atmosphere's mixture of gases.
Explanation:
In addition to oxygen, the gases that make up the largest percentage of Earth's atmosphere may significantly include nitrogen, argon, carbon dioxide, etc.
Why oxygen is essentially required for living organisms?Oxygen is essentially required for living organisms because it helps organisms grow, reproduce, and turn food into energy. Humans get the oxygen they need by breathing through their noses and mouth into their lungs.
Oxygen gives our cells the capability in order to break down food in order to get the energy they need to survive. Oxygen consists of 21% of the total earth's atmosphere along with 78% of the nitrogen and 1% of all rest of the gases like argon, carbon dioxide, etc.

Approximately how many genes are found on
chromosome 112|
Answer:
Down syndrome, Turner syndrome and Klinefelter syndrome.
Explanation:
Down syndrome, Turner syndrome and Klinefelter syndrome are the genetic disorders which are found in chromosome. Down syndrome is a common genetic disorder that occurs when a person has three copies of 21st chromosome. It is also called trisomy 21. Due to this disorder, delays occur in physical and mental developmental and disabilities of human body parts.

1. Chromosome 11 is made of over 130 million base pairs.
2. Approximately how many genes are found on

3. autism (neurexin 1), acute intermittent porphyria, albinism, ataxia-telangiectasia, Beckwith–Wiedemann syndrome, Best's disease, beta-ketothiolase deficiency, beta thalassemia.
4.Autism is related to some changes in chromosome 11, although it is characterized as a psychological disorder. It is usually identified in childhood, between 1 and a half years and 3 years, although the initial signs sometimes appear in the first months of life. The disorder affects the child's communication and ability to learn and adapt. Chromosome 11 Duplication Syndrome is a chromosomal alteration that interferes with child development, which may trigger motor, cognitive, language and socialization delays, inability to perform simple motor activities, weight and height deficit, facial dimorphisms and congenital malformations. Jacobsen's syndrome is an inherited disorder caused by the deletion of a specific region of the long arm of chromosome 11, which covers the 11q24.1 band. Patients with this disorder have a phenotype characterized by delayed neuropsychomotor development, craniofacial anomalies, diverse heart defects and blood dyscrasias. Signs and symptoms include: Heart defects; mental delay; difficulty feeding in childhood; attention deficit; hyperactivity; skeletal malformation, among others.

Development of only one Pollen Grain from microspore Mother cell is reported in family
Answer:
Pollen grains are produced by meiosis of microspore mother cells that are located along the inner edge of the anther sacs (microsporangia). ... The tube cell (also referred to as the tube nucleus) develops into the pollen tube. The germ cell divides by mitosis to produce two sperm cells.
the chart below lists substances involved in the process of photosynthesis
which statement best describes how these substances interact in photosynthesis
Answer:
C and D combine to produce A and B.
Explanation:
The chart you were given is shown in the image I attached below. The options you were given are the following:
A and B combine to produce C and D. C and D combine to produce A and B. B and C combine to produce A and D. A and C combine to produce B and D.Photosynthesis is a process in which organisms that possess the pigment called chlorophyll (most plants and some protists and bacteria) produce the energy necessary for their survival. With the help of sunlight, they convert water (D), carbon dioxide (C), and minerals into oxygen (B) and glucose (A).
This is why the second option is the correct one.
Answer:
c and d combined to produce both A and B
Explanation:
how does proteinsynthesis happen in the ribosome
First of all, transcription needs to happen inside the nucleus. An enzyme called RNA polymerase uses a strand of DNA as template for mRNA (messenger RNA) synthesis. The mRNA contains the codons. The next step of protein syntheis is called translation and occurs in the ribosome. Codons are groups of three letters that code for an amino acid. When the mRNA comes to the ribosome each codon pairs with an anticodon. Groups of three base pairs that are complementary to codons and are present in the tRNA(transfer RNA).
Each tRNA molecule has an amino acid attached to it and a specific anticodon. Depending on the order of codons proteins are build by binding amino acids.
What do animal cells need to make energy?
Answer: Eating.
Explanation:
Animals obtain energy by eating plants or animals. The only form of energy a cell can use is a molecule called adenosine triphosphate (ATP). Chemical energy is stored in the bonds that hold the molecule together. ADP can be recycled into ATP when more energy becomes available.
Answer:
Food
Explanation:
Animals obtain energy when they eat. So do we, because we have animal cells! If you don't eat you will get weak and your body needs the nutrients that it gets from the food that you eat. So to make adenosine triphosphate (ATP), you need energy and some other factors that go into making ATP.. but that is the just of it.
You need food.

What type of mechanism is blood sugar
Answer:
Blood sugar regulating mechanism is operated through liver and muscle by the influence of the pancreatic hormones- insulin and glucagon.
Explanation:
... hope this answer may help u.... and for more answers follow me.❤️❤️❤️Your question is interpretable but the mechanism for blood sugar regulation is called negative feedback.This means that when the blood sugar levels increase an enzyme called insuline comes into play and decreases the levels of blood sugar by glycogeneis(syntheis of glycogen) and increases the membrane permeability of cells for glucose. When glucose level decreases an enzyme called gucagon functions that has opposite effects.

Zara had a birthday and was able to choose a pet. The pet that she chose was a beautiful clownfish named Bozo, a common salt water fish. Zara already has a tank with goldfish at home. Use your knowledge of diffusion & osmosis to tell Zara how to take care of Bozo.
Answer:
See the answer below
Explanation:
Zara should keep Bozo in a separate salt water-containing tank away from the goldfish.
Bozo is adapted to living in salt waters. If it is kept in saltless water like the goldfish, its cells would lyse and the fish may die. The saltless water would be hypotonic to the cells of Bozo and water moves osmotically from a region of high water potential to a region of low water potential. Hence, the cells of Bozo would take-in water, become turgid, and may eventually lyse, leading to the death of the fish.
The goldfish cannot survive in salt water with Bozo because the water would be hypertonic to its cells. Hence, it will lose water to the surrounding salt water due to osmosis and may eventually die of dehydration.

9. Halobacterium has a photosynthetic membrane that is colored purple. Its photosynthetic action spectrum is exactly complementary the action spectrum for green plants. What wavelengths of light do the Halobacterium photosynthetic pigments absorb
Answer:
Yellow-green
Explanation:
Let us remember that the colour that is transmitted is always complementary to the colour that is absorbed.
Hence, if a substance absorbs a particular colour, it will transit the colour complementary to that absorbed colour.
The complementary colour of yellow-green is purple hence yellow green light of wavelength 560 - 580 nm is absorbed.

What are polymers? Through which process are they synthesized or made?
Answer:
Polymers are large molecules with a chain structure that can be linear, branched, and cross-linked. Polymer chains are mainly composed of covalently bonded atoms.
Explanation:
Polymers can be synthesized using reactants of petrochemical or renewable origin. Polymers can be synthesized in two methods, by step-growth and chain polymerization. Both ways of polymerization are random processes during which chains of different lengths are formed.
The basis of step-growth polymerization is the condensation reaction.
