Why do you think that some vaccines, such as the flu vaccine, need to be given every year?

Answers

Answer 1

Answer:

Because flu viruses evolve so quickly, last year's vaccine may not protect you from this year's viruses. New flu vaccines are released every year to keep up with rapidly adapting flu viruses.

Answer 2

Answer:

Because the virus/sickness would evolve and that vaccine might not protect you.

I need a small text (about 50 words) for the human brain.

Answers

Answer:

The human brain is the command center for the human nervous system. It receives signals from the body's sensory organs and outputs information to the muscles. The human brain has the same basic structure as other mammal brains but is larger in relation to body size than any other brains.The largest part of the human brain is the cerebrum, which is divided into two hemispheres, according to the Mayfield Clinic. Underneath lies the brainstem, and behind that sits the cerebellum. The outermost layer of the cerebrum is the cerebral cortex, which consists of four lobes: the frontal, parietal, temporal and occipital. [Nervous System: Facts, Functions & Diseases]

Like all vertebrate brains, the human brain develops from three sections known as the forebrain, midbrain and hindbrain. Each of these contains fluid-filled cavities called ventricles. The forebrain develops into the cerebrum and underlying structures; the midbrain becomes part of the brainstem; and the hindbrain gives rise to regions of the brainstem and the cerebellum.

B) the temperature seasonal Forest is cooler and wetter than the tropical rainforest

C) the temperature seasonal Forest has warmer average temperatures than the Boreal forest

D) the temperature seasonal rainforest has similar temperatures but less rain than the temperate rainfores

E) the temperature seasonal rainforest has similar rainfall to the Boreal and tropical seasonal rainforest, but is much warmer than either one​

Answers

Answer:

The correct answer is - A and C,

Explanation:

According to the graph, the following conditions are matched correctly with the temperature seasonal forest with other biomes:

The temperature seasonal forest has the precipitation range from 50 cm to 250 cm rainfall per year approximately. The average rainfall from this would be 150 cm/year or between 100 to 200 cm per year.

B. the temperature seasonal forest has a temperature between 15 degrees Celsius to 20 degrees celsius which is warmer than the boreal forest that has a temperature between 0 to 15 degrees Celsius approximately.

Lion and cheetah populations compete for the food source of zebras, and cheetahs outcompete lions.

Answers

Answer:

The dwindling zebra population has led to the decline of the predator lion and cheetah populations.

Explanation:

The decrease in zebra population also decreases the population of the predator lion and cheetah because both predators depends on zebra for their survival. Both predators used zebra as a source of food for their growth and survival so if there is high availability of zebra so the population of Lions and cheetah also increases while on the other hand, if there is decrease in zebra population, the population of lion and cheetah also decreases because of less available food for them.

Answer:

B) The dwindling zebra population has led to the decline of the predator lion and cheetah populations.

Use the images below to answer the question. 2. What makes all of the samples different from each other?​

Answers

Answer:

Shape and structure.

Explanation:

The difference in shape and structure of these pictures is responsible for the difference from each other. The organisms present in these pictures are different in their size, shape and composition of their body. Some are small and some are large, some are living while the others are non-living, some are very hard whereas the others are soft and fleshy. So the organisms present in these samples are different from each other in a variety of ways i.e. size, shape and body structure.

Outline the process of the Carbon Cycle.

Answers

Answer:

Carbon Cycle Definition

Carbon cycle is the process where carbon compounds are interchanged among the biosphere, geosphere, pedosphere, hydrosphere, and atmosphere of the earth.

Carbon Cycle Steps

Following are the major steps involved in the process of the carbon cycle:

Carbon present in the atmosphere is absorbed by plants for photosynthesis.

These plants are then consumed by animals and carbon gets bioaccumulated into their bodies.

These animals and plants eventually die, and upon decomposing, carbon is released back into the atmosphere.

Some of the carbon that is not released back into the atmosphere eventually become fossil fuels.

These fossil fuels are then used for man-made activities, which pumps more carbon back into the atmosphere.

Outputs----- ATP, carbondioxide and water.

Explanation:

The inputs of cellular respiration are the glucose and oxygen whereas the outputs of cellular respiration are energy in the form of ATP, carbondioxide gas and water. cellular respiration is a process in which glucose is broken down in the presence of oxygen gas for the production of energy in the form of ATP molecules. Carbondioxide gas and water which are the waste materials also produced in the end of cellular respiration process. Cellular respiration is the reverse of photosynthesis.
