Mendel concluded that the alternative forms of each trait are coded by discrete factors, which were called alleles that combine in pairs to express the trait. Traits are inherited in discrete units and are not the result of "blending."

------------------------

After making many crosses that involved different traits -such as plant height, or flower colors-, Mendel observed that, per trait, the F1 only expressed one of the alternative forms, while de other one disappeared.

Mendel named dominant the expressed variant.

Mendel then let these new plants auto pollinate and observed the results in the second generation, F2.

He saw that the variants that had previously disappeared among the F1, reappeared again. Both alternatives for each trait were present in the F2.

Mendel named recessive the second alternative variant.

Mendel explained his results by arguing that discrete factors were responsible for these phenotypes.

Mendel conclusion about his experiments was that per trait -flower color of plant length-, each plant had a pair of factors -which he named alleles-, and that each factor coded for one of the alternative forms of the traits -white or purple, tall or short-.

He thought that alleles separate -segregate- during the process of gamete formation.

The First Mendel's Law is the first conclusion he took about his experiments and is known as the segregation principle.

Answer:

Your lungs contain many small, elastic air sacs called alveoli. With each breath, these air sacs take in oxygen and release carbon dioxide. Normally, this exchange of gases occurs without problems. But sometimes, the alveoli fill with fluid instead of air, preventing oxygen from being absorbed into your bloodstream.

Explanation:

Answer:

The fluid represents the outermost layer of the alveolar surface that is directly exposed to air and thus to the environment. Alveolar fluid prevents desiccation of the epithelial cells and also functions as a physical protection barrier against inhaled particles and irritants.                                        Explanation:     hope this helps

Answer:

Archaebacteria

Archaebacteria are the most recent addition to the kingdoms of organisms. Their existence was not discovered until the 1980s. However, Archaebacteria are the oldest known living organisms. They are single-celled and thrive in extremely hot boiling water found in environments like volcanic thermal vents in the ocean and hot springs like the geysers at Yellowstone Park. Some species also live in very salty environments such as The Dead Sea and The Great Salt Lake.

Eubacteria

Eubacteria are also single-celled bacterial organisms. This kingdom makes up most of the bacteria in the world. Eubacteria are very common and well-known to us as parasites like Streptococci which causes strep throat. However, these bacteria also help produce many antibiotics, vitamins and yogurt.

Fungi

The Fungi kingdom is recognizable to us as mushrooms, molds, mildews and yeasts. Unlike the organisms in the Archaebacteria and Eubacteria kingdoms, Fungi are multi-celled organisms. Early scientists classified mushrooms and other fungi in the Plant kingdom but they do not produce their own food as plants do.

Protista

Protista or Protozoa are single-celled organisms, but are more complex than single-celled bacteria. The Protista kingdom includes algae and slime molds. Any microscopic organism that does not fall into the bacterial, fungi, plant or animal kingdoms is considered a part of the Protista kingdom.

Plants

The Plant or Plantae kingdom encompasses all flowering plants, mosses and ferns. Plants are multi-celled, complex organisms and are considered Autotrophic. This means that plants create their own food through photosynthesis. The Plant kingdom is thought to be the second largest with over 25,000 known species.

Animals

The largest kingdom of organisms is the Animal or Animalia kingdom. This kingdom is made up of complex, multi-celled organisms ranging from sea sponge colonies to elephants. All organisms in the Animal kingdom are Heterotrophs meaning, unlike plants which produce their own food, animals feed upon other organisms. The Animal kingdom is the world's largest with over one million known species.

Explanation:

The type of resources from much more slowly than we use them is non-renewable resource. The correct option is D.

A non-renewable resource is a natural resource that cannot be replaced quickly enough by natural means to keep up with consumption.

Carbon-based fossil fuels are one example. With the help of heat and pressure, the original organic matter is converted into a fuel such as oil or gas.

Nonrenewable energy sources are not only affecting our planet's atmosphere by increasing greenhouse gas emissions.

Coal and oil combustion emits particles that can pollute the air, water, and land. Some of these particles are captured and stored, but many are released into the atmosphere.

The use of fossil fuels also disrupts Earth's "carbon budget," which balances carbon in the ocean, earth, and atmosphere.

Thus, the correct option is D.

Explanation:

What is a DNA fingerprint?

DNA fingerprinting is a method used to identify an individual from a sample of DNA by looking at unique patterns in their DNA.

Background

Almost every cell? in our body contains our DNA?.  

On average, about 99.9 per cent of the DNA between two humans is the same.  

The remaining percentage is what makes us unique (unless you are an identical twin!).  

Although this might sound like a small amount, it means that there are around three million base pairs? that are different between two people. These differences can be compared and used to help distinguish you from someone else.  

Minisatellites are short sequences (10-60 base pairs long) of repetitive DNA that show greater variation? from one person to the next than other parts of the genome?. This variation is exhibited in the number of repeated units or ‘stutters’ in the minisatellite sequence.

The first minisatellite was discovered in 1980.  

DNA fingerprinting

DNA fingerprinting was invented in 1984 by Professor Sir Alec Jeffreys after he realised you could detect variations in human DNA, in the form of these minisatellites.  

DNA fingerprinting is a technique that simultaneously detects lots of minisatellites in the genome to produce a pattern unique to an individual. This is a DNA fingerprint.

The probability of having two people with the same DNA fingerprint that are not identical twins is very small.  

Just like your actual fingerprint, your DNA fingerprint is something you are born with, it is unique to you.

How was the first DNA fingerprint produced?

The first step of DNA fingerprinting was to extract DNA from a sample of human material, usually blood.

Molecular ‘scissors’, called restriction enzymes?, were used to cut the DNA. This resulted in thousands of pieces of DNA with a variety of different lengths.

These pieces of DNA were then separated according to size by a process called gel electrophoresis?:

The DNA was loaded into wells at one end of a porous gel, which acted a bit like a sieve.  

An electric current was applied which pulled the negatively-charged DNA through the gel.

The shorter pieces of DNA moved through the gel easiest and therefore fastest. It is more difficult for the longer pieces of DNA to move through the gel so they travelled slower.

hypothalamus

The part of the diencephalon that is in the anterior and inferior region of the diencephalon is the Hypothalamus.

The hypothalamus exists a portion of the brain that includes a numeral of small nuclei with a combination of functions. One of the most important operations of the hypothalamus exists to link the nervous system to the endocrine system via the pituitary gland. The hypothalamus exists discovered below the thalamus and exists as part of the limbic system. The terminology of neuroanatomy, includes the ventral part of the diencephalon. All vertebrate brains include a hypothalamus. In humans, it stands the size of an almond.

The hypothalamus stands answerable for the regulation of specific metabolic functions and other actions of the autonomic nervous system. It synthesizes and secretes certain neurohormones, named releasing hormones or hypothalamic hormones, and these, in turn, promote or inhibit the secretion of hormones from the pituitary gland. The hypothalamus influences body temperature, hunger, important aspects of parenting and affection manners, thirst, fatigue, sleep, and circadian rhythms.

Hence, The part of the diencephalon that is in the anterior and inferior region of the diencephalon is the Hypothalamus.
