Answer:
Deletion
Explanation:
Deletion is the act of a gene being removed from a chromosome, making it mutated.
Answer:
There are many questions that can be answered by science but I will provide some examples below.
Explanation:
Science involves many areas of study, <u>from biology and chemistry to physics and neuroscience</u>. Generating questions and providing answers are the most important steps in science as this process has allowed thousands of scientists to develop new drugs to treat previously-mortal diseases, to protect endangered species, to prevent population declines, to understand the behavior of fauna, among many other remarkable outcomes and discoveries.
In this answer, I will focus on some questions belonging to the life sciences areas that can be answered by science:
Biology
<em>How does climatic phenomena, such as El Niño and La Niña, affect the migration of whales?</em>
<em />
Neuroscience (humans)
<em>Is schizophrenia hereditable?</em>
<em />
Behavioral Ecology
<em>Does climate change affect the capability of cuttlefish to camouflage?</em>
Neuroscience (Animals)
<em>Are killer whales capable of problem-solving?</em>
<em />
Ecology
<em>How does the reduction of apex predator populations (terciary consumers) affect the population of secondary consumers?</em>
<em />
Conservation Biology
<em>Why do increased temperatures lead to coral bleaching? What is the mechanism and how can it be controlled?</em>
<em />
Animal Behavior
<em>What is the mechanism that Ophiocordyceps unilateralis (Zombie fungus) uses to manipulate ants for its own disperal?</em>
<em />
Parasitology
<em>Does the parasite Toxoplasma gondii induce erratic behaviors in humans?</em>
Answer:
Personality.
Explanation:
The mental disorders affects the thinking ability of the individual. The mental disorder individual shows abnormal behavior in the society and might feel anxiety or feel awkward among the people.
The personality disorder is a type of the mental disorder in which the individual have unhealthy thinking level. This disorder affects the social status and his personality in the society. The occupational functioning become improper and requires the proper medical treatment.
Thus, the answer is personality.
Tundra and deserts are two biomes of the world which represent the extreme form of climates. Tudra is the coldest region of the earth while desert represent the hottest zones of the earth. But whats the most common thing in these extreme zones is that they receive very less precipitation throughout the year (less than 25 cm).
Therefore, flora of the desert and Tundra have some special adaptations to survive without sufficient amount of water.
Let's see what are those:
- The height of plants growing in Tundra is very less like lesser than 1 foot. The short structure of the plants helps them to get more heat from the dark soil and helps to survive freezing. The short height lets them stay protected from harsh effects of cold or snow.
- The plants in tundra grow in groups or clumps that helps them in surviving the attacks of ice particles or snow balls. For example: lousewort and Arctic crocus.
- Some flora of tundra has ability to grow even in the complete lack of water for several years.This is because they have waxy layers that cover the leaves and store maximum water for the periods of no availability.
- Some plants have hair on the surface of stems that trap maximum heat and protect the plant from heat and extreme forms of wind. For example: Arctic crocus.
- Desert plants not only have physiological but also morphological adaptations to survive heat stress and shortage of water. Their stems, roots and leaves are fleshy and help them to store water for a large period of time. For example: Cactus
- Many desert plants like <em>xerophytic bromeliads</em> and <em>epiphytic orchids </em>contain a system alternate of photosynthesis called CAM (Crassulacean Acid Metabolism). This process helps the plant to open the stomata at night for exchange of gases and accumulate CO2. In day, stomata are closed and the CO2 is used for photosynthesis. This is an adaptation, because during night when temperature is low, CAM plants lose less water as compared to what normal plants lose during day.
- Some plants have extremely large roots that absorb maximum water from soil and compensate the plant's loss of water due to heat. For example: Phreatophytes.
- Some Perennial plants have adapted the mechanism to stay in condition of rest or dormant during extreme heat. They get back to normal life when weather become a bit better.
Hope it helps! :)
