Many animals have been in space, including multiple monkeys, dogs, cats, bullfrogs, spiders, newts, and microscopic animals called water bears. Water bears are known for their resilience and were able to withstand a 10 day exposure to open space. One of the more famous animals sent to space was a little Soviet dog named Laika, sent into orbit in 1957 on a small satellite. Laika has since had children’s books and songs written about her.

Although parvoviruses are the smallest viruses, they are not recognized as the smallest living things, because they need a host cell in order to reproduce. The smallest living thing belongs to a group of bacteria known as mycoplasmas. Mycoplasmas are about 90 nanometers in size, which is bigger than the parvoviruses but smaller than other viruses. Some of these bacteria can infect animals, plants, insects and humans.
What determines whether an organism is heterozygous or homozygous dominant?

During the production of gametes for sexual reproduction, half the DNA of the parent organism is copied into the gamete cell. However, the chromosomes of the gamete are not identical to either of the chromosome pairs of the parent organism. This is because of genetic recombination, where the DNA from the parent's paired chromosomes are mixed together. This results in a unique combination of genetic traits on the gamete's chromosomes, but no genes are new to the gamete without mutation. If the parent is homozygous, then the gamete carries a copy of the homozygous gene despite recombin..

When the fatty acids are identical, the triglyceride is known as simple. Mixed triglycerides contain two or three different fatty acids. Triglycerides are present in both plant and animal species. In plant species, triglycerides are found in the cell membrane and are mostly unsaturated. In animals, they are saturated.\nTriglycerides are an important energy source present in adipocytes, or fat cells, and blood cells of animals. Triglycerides are the major component of all fats and oils.

The bending of the wrist is aided by flexor carpi radialis and flexor carpi ulnaris. Flexor digitorum profundus aid in bending fingertips. Flexor digitorum superficialis can bend the middle sections of the fingers. Flexor pollicis longus and flexor pollicis brevis aid in bending thumbs.\nFlexor digiti minimi brevis manus works on the little finger. The four smaller toes bend through the actions of flexor digitorum longus and flexor digitorum brevis. The great toe is bent by flexor hallucis longus and flexor hallucis brevis. The flexor digiti minimi brevis pedis aids in bending the smallest toe..

Poikilocytosis is a general term because clinicians must determine what causes the variations in shapes. MediaLab Incorporated states that accurate diagnosis of red blood cell morphology is possible through scanning electron microscope technology. Such scans greatly increased hematologists' understanding of abnormal red blood cells.\nConfirming an anemia diagnosis may include detecting the presence of these abnormally shaped cells, measuring serum ferritin and checking hemoglobin levels in blood. Patient.co.uk indicates that iron-deficiency anemia can be solved by diet and iron supplement..
What type of wave is sound?

A sound wave is a type of pressure wave caused by the vibration of an object in a conductive medium such as air. When the object vibrates, it sends out a series of waves that are interpreted as sound. The vibrations travels at different speeds through different types of mediums and all mechanical waves require a medium through which they can move. Since space is a vacuum, sound does not travel in space.
What is a substantial derivative?

What this means is that instead of tagging each particle in the flow, one simply needs to fix a volume in space to identify the properties of flow present in that particular space. This renders the particles that pass the volume irrelevant because that particle eventually resumes the flow property found in that space.

Milne spent many years studying earthquakes in Japan due to the high volume of these ground-shaking events. He was given the nickname Earthquake Milne and was considered the father of seismology. After leaving Japan in 1895, he moved to the United States where he created an observatory that is now considered the center for earthquake science. Milne and his science partners Alfred Ewing and Thomas Gray created the Seismological Society of Japan.

The fissure does not completely divide the left and right hemispheres of the cerebrum. There is a band of white matter called the corpus callosum that connects the right and left hemispheres and is also how they communicate. Each side of the brain controls the opposite side of the body: the left hemisphere controls the right side of the body, and the right controls the left. If there is damage or a tumor on the left hemisphere, a person's right arm and leg may be weakened or paralyzed. The left and right hemispheres do not share all functions however. The right hemisphere is responsible f..
