Answer:
Helper T cells
Explanation:
This is because it is a type of adaptive immune system that stimulate B cells, microphages and cytoxic T cells. Helper T cells are used in different adaptive immune responses. They help to activate B cells so as to produce antibodies and also help macrophages to destroy ingested microbes. they also help activate cytotoxic T cells which will inturn kill infected target cells.
Reproduction in amoebas involves endocytosis, while reproduction in red algae involves spore formation.
The amoebas have to use endocytosis for photosynthesis while the red algae use pinocytosis during photosynthesis.
Endocytosis is the only way amoebas can bring food into their cells, while red algae can produce food by photosynthesis.
The correct answer is -- Endocytosis is the only way amoebas can bring food into their cells, while red algae can produce food by photosynthesis.
Amoeba is an unicellular organism. It is an heterotroph follows holozoic nutrition. It engulf its food with the help of pesudopodia. engulfing of solid food is called endocytosis, whereas red algae such as Polysiphonia is an autotroph which synthesis its own food by the process of photosynthesis. thus, in red algae endocytosis does not occur.
Answer:
False
Explanation:
The eye spot instead creates a disguise and used to misdirect predators. The eyespots are a defense mechanism for the organism. Scientists have tested this by painting eye spots on a gake prey and a fish was used a s the predator. The predator was discovered to have attacked the fake eyespots more often as it thought it was the prey's head.
Eyespots on a prey can also make the predator to think that it is facing a larger animal. An example is the butterfly which have large false eyes on its wings.
Answer:
The rock on the right is foliated
Explanation:
There are three types of rocks. Metamorphic, igneus and sedimentary.
Igneus rocks are formed from magma that cooled in one point of earth history, so non of the metamorphic rocks is formed from cooled magma.
Sedimentary rocks are formed from varios sediments or grains that after processes of pression or temperature compact together. So, metamorphic rocks are not formed from randomly arranged grains
Metamorphic rocks are rocks that change their shape for a phisical reason. One common way to find metamorphic rocks is foliated, this means that the rock has layers. Like a book, with different sheets.
When a metamorphic rock is formed from granite, the pattern is foliated, with layers and the form of the rock is usually banded, this rock is called Gneiss. The left image is not layered.
The right image is layered like sheets, this is the only option that has no counter arguments
The question is incomplete as it lacks multiple options. The options are as follows:
Notify the primary healthcare provider
Check the chest tube for patency
Inspect the incision for bleeding
Auscultate the left lung
Answer:
Auscultate the left lung
Explanation:
Pneumonectomy may be defined as the surgical procedure of the removal of lung or its part. The pneumonectomy is mainly performed in case of the lung tumors.
The auscultation is the procedure of listening different sounds of the hear and lungs. The auscultation is important as after the surgery the airway obstruction might occur and may also cause the trachea deviation. The proper lung sound do not require any medical procedure but abnormal sound require emergency medical procedure.
Thus, the correct answer is option (4).
Answer:
During a 30-year period, the yearly frequency of drought is 10%,
Explanation:
Answer:
frictional
Explanation:
This scenario follows Newton's third law of motion which alludes to the fact that for every force or action exerted by a person on a body there is an equal and opposite reaction exerted back.
Because there is a limited frictional force (a force exerted by an object when an object moves across it) between
Here, the paddle helps the boatman apply a force on the water, resulting in the opposite amount of force been sent back; pushing the boat forward.
