When a signal molecule binds a membrane receptor, different intracellular events occur in response. Option D is correct: All of the above.
What is signals translation and how is it done?Signal translation is the conversion global process of extracellular signals into intracellular responses. This porcess is done by a translator.
Translation might be
INDIRECT ⇒ Second messengers participate in the signal translation, mediating between receptor and the cellular response.
The receptor-ligand union causes the production of second messengers that will activate effector proteins. Occurs an amplification of the signal.
DIRECT ⇒ Occurs directly in the membrane.
Ionic channel proteins are activated and can change the chemical signal into an electric signal through ion flow.
When the molecule binds receptors that are associated with enzymes -or acting as enzymes- or to G proteins, it occurs a conformational change in the receptor cytoplasmic domain.
This change triggers an intracellular signal cascade in which many molecules participate and several chemical changes occur.
According to this framework, all the options are correct,
The receptor can open an ion channel in the cell membrane.The receptor can act as an enzyme causing chemical changes in the cytoplasm.The receptor can cause the formation of a second messenger.So te correct option is Option D. All of the above.

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.

C)
Mangrove forests help mitigate storm damage.
D)
The world’s largest remaining tract of mangrove forest is in Australia.
E)
Mangroves have only one type of root system.
Answer:
E. Mangroves have only one type of root system
Explanation:
Mangrove species are those species of plants found in a saline environment. The soil they are found is usually shallow and swampy (water-logged). They possess characteristics feature that helps them adapt and survie in their habitat.
One of those features is the possession of PNEUMATOPHORES OR BREATHING ROOTS, which is a kind of root system that extends out so that the pores on them can allow the intake of gases directly from the atmosphere.
The statement that is true about mangroves is that mangrove forests help mitigate storm damage. The correct answer is option C.
Mangroves are a type of coastal tree that are able to grow in saltwater. They are found in tropical and subtropical regions around the world, and they play an important role in coastal ecosystems.
Mangrove forests are able to mitigate storm damage by acting as a natural barrier against storm surges and waves. The dense root system of mangroves helps to stabilize shorelines and prevent erosion, while the trees themselves can absorb a significant amount of the energy from storm waves. Mangroves are also important habitats for a variety of marine and terrestrial species, including birds, fish, and reptiles.
Therefore, the statement that best describes mangrove forest is option C.

Describe and give and example of a fibrous joint, a cartilaginous joint, and a synovial joint.
Articulaciones sinoviales
Las articulaciones sinoviales son conexiones entre componentes esqueléticos en las que los elementos implicados se encuentran separados por una estrecha cavidad articular. Además de incluir una cavidad articular, estas articulaciones tienen varios rasgos característicos.
En primer lugar, una capa de cartílago, habitualmente cartílago hialino, cubre las superficies articulares de los elementos esqueléticos. En otras palabras, las superficies óseas no contactan normalmente entre sí de forma directa. Como consecuencia, cuando se ven estas articulaciones en radiografías normales, un amplio intervalo parece separar los huesos adyacentes, porque el cartílago que cubre las superficies articulares es más transparente a los rayos X que el hueso.
Una segunda característica de las articulaciones sinoviales es la presencia de una cápsula articular consistente en una membrana sinovial interna y una membrana fibrosa externa:
La membrana sinovial se fija a los márgenes de las superficies articulares en la interfase entre el cartílago y el hueso, y envuelve la cavidad articular. La membrana sinovial está altamente vascularizada y produce líquido sinovial, que se acumula en la cavidad articular y proporciona lubricación a las superficies articulares. También aparecen sacos cerrados de membrana sinovial fuera de las articulaciones, donde forman bolsas sinoviales o vainas tendinosas. Las bolsas se interponen a menudo entre estructurahttp tendones y hueso, tendones y articulaciones, o piel y hueso, y reducen la fricción de una estructura al moverse sobre otra. Las vainas tendinosas rodean los tendones y también disminuyen la fricción.
La membrana fibrosa está formada por tejido conjuntivo denso y rodea y estabiliza la articulación. Partes de la membrana fibrosa pueden verse engrosadas para formar ligamentos, que estabilizan aún más la articulación. Los ligamentos externos a la cápsula suelen aportar un refuerzo adicional.

Explanation:
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.
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.

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.
