Which body system releases heat through muscle contractions to maintain an optimal body temperature?
Answer:
Skeletal muscles
Explanation:
Skeletal muscles contribute to maintaining temperature homeostasis in the body by generating heat. Muscle contraction requires energy and produces heat as a byproduct of metabolism.
Choose all of the muscles capable of dorsiflexion.
A. tibialis posterior
O B. extensor hallucis longus
o C. fibularis longus
OD. extensor digitorum longus
O E. flexor digitorum longus
O F. tibialis anterior
N
answer:F tibialis anterior
There's one muscle on the front of the leg for dorsiflexion, tibialis anterior. Tibialis anterior arises from the lateral surface of the upper tibia, and from the interosseous membrane.
The muscles capable of dorsiflexion are the extensor hallucis longus, extensor digitorum longus, fibularis tertius, and tibialis anterior. Options B, D, E, and F are correct.
The anterior tibialis muscle is located next to the tibia’s lateral surface. This muscle is the strongest of the foot’s dorsiflexion. It’s attached to the big toe’s base.
The main mechanism of action is to stretch the lateral four fingers at the metatarsophalangeal joint. In other words, when acting alone, it can’t stretch the whole length of the fingers, it can only stretch the fingers at the metatarsophalangeal, and at the interphalangeal joints, the fingers remain flexed.

Aquatic organisms are able to survive when the temperature decreases. These organisms survive even when the surfaces of lakes and ponds are covered with ice. Which property of water best explains how aquatic organisms can survive during freezing temperatures?
A.
Water molecules are attracted to the surface that has a charge
B.Water expands when it freezes, so solid water is less dense than liquid water
C.It takes a large amount of energy to increase the temperature of the water
D.The positive charges of water’s hydrogen atoms are attracted to the negative charge of its oxygen atoms
Answer:
B. Water expands when it freezes, so solid water is less dense than liquid water
Explanation:
The molecules of water expands or increases in volume when it is freezed i.e. at a low temperature. This allows the solid state of water (ice) to be less dense than the liquid state (water). Hence, because ice is less dense than water, IT FLOATS. Therefore, in a water body whose temperature is low, the ice component floats on the surface, with liquid water beneath.
Due to this DENSITY property of ice (low) and water, aquatic organisms like fishes are able to survive and live just fine beneath a water body covered with ice. Note that, oxygen is trapped in the liquid portion of the water body underneath the ice covering.

Group II viruses violate the Central Dogma. Is the highlighted statement above true or false and why? In the blank space below, you must indicate if you think the highlighted statement above is True or False, AND you must pick one of the rationals for your choice from the list presented below. Your answer should follow the form of the word True or False immediately followed by a number. For example, False3 would mean you think the statement above is false, because Group II Viruses use a DNA genome as a template for DNA, which is then transcribed to mRNA. The Central Dogma is DNA -> RNA -> Protein. Group II viruses use a DNA -> DNA -> RNA -> Protein pathway Group II Viruses still use a DNA genome as a template for anti-sense DNA, which is then used as a template for RNA, which is then translated to proteins. This is still DNA -> RNA -> Protein. Group II Viruses use an RNA genome as a template for for proteins. Group II Viruses use a DNA genome as a template for DNA, which is then transcribed to mRNA. The Central Dogma is DNA -> RNA -> Protein. Group II viruses use a DNA -> DNA -> RNA -> Protein pathway.
Answer:
The statement is false
Explanation:
This type of virus is characterized by the presence of only one DNA strand. For this virus, the mechanism of infection is only effective against vegetal cells. After the introduction of the viral DNA inside of the host cytosol. The present proteins auxiliate synthesize the virus DNA and the antisense strand; transforming the single-stranded DNA into double-stranded DNA. In this way, the virus DNA is read by the transcription mechanism of the host, resulting in new virus proteins.
Since it follows the normal gene transcription: it not goes against the normal rule. Consequently, the statement is false.

Come up with another myth about the classification of organisms. Then, give two to three reasons why the myth is untrue. Use complete sentences and support your answer with evidence, using your own words.
Your myth:
o Fact:
o Evidence:
Answer:
Myth: A dead organism is the same as a nonliving thing in science.
Fact: According to science when an organism dies it not different from a non-living thing
Evidence: Non-living things are fundamentally different than living organisms mainly because of the differences in their chemical and biological structures. Living things are made of biomolecules, complex polymers like lipids, proteins, and polysaccharides based on carbon and non-living things are usually made of minerals and other inorganic compounds. So, even if an organism is dead, we can determine that it was a living thing by analyzing its chemical structure.
Myth: The Linnaeus system of classification will always stay the same.
Fact: Carl Linnaeus, a Swedish scientist from the 18th century came up with the perfect classification system that is used up to this day unchanged.
Evidence: Although this system is still widely used to classify living organisms, it has gone through some changes. Linnaeus considered kingdoms to be the utmost level of classification, but biologists today recognize a level above kingdoms, the level of domains. Some scientists also argue that classifying organisms into kingdoms should be abandoned, because not all organisms traditionally divided into kingdoms have the same origin.
