Answer:
A
Explanation:
Both cilia and flagella are important locomotory organs. These organelles are specialized to cause the movement of the cell from one place to another in the environment. Thus, the correct option is A.
What are locomotory organs?Locomotion is the directional movement of cells that enables something to move from one place to another place. The word locomotion is derived from the Latin words loco which means place and motio means to move.
The anatomical structures which animals posses for the movement, includes cilia, legs, wings, flagella, or tails, these are referred to as the locomotory organs. These are present on the body of animals to defend themselves in extreme conditions, in capturing the food or prey. The cilia are hair-like organs which are present all over the surface of a cell where flagella is a large whip-like structure which are present single or in pair in a cell.
Therefore, the correct option is A.

Name the explanation for this phenomenon and describe the mechanism.
Due to homeostasis, the heart pumps more volume of blood per minute from the left ventricle after a greater volume of blood enters the right atria of the heart.
What is homeostasis?Homeostasis is the process by which the body maintains a fairly constant internal environment.
Homeostasis is concerned with ensuring balance in the functions of the body.
Since a greater volume of blood enters the right atria of the heart human heart, the heart pumps more volume of blood per minute from the left ventricle in order to maintain balance of blood flow throughout the body.

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.

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.

Mangroves grow on low-energy coasts.
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.
