Answer:
Purse seines
Explanation:
Purse seines are used in the open ocean to target dense schools of single-species pelagic (midwater) fish like tuna and mackerel. A vertical net 'curtain' is used to surround the school of fish, the bottom of which is then drawn together to enclose the fish, rather like tightening the cords of a drawstring purse.

Plants lose __ % water to transpiration resulting in 10% increase in atmospheric water vapor which increases relative humidity and chance of precipitation.
A: 90
B: 10
C: 100
D: 45
Answer: A
Explanation: Transpiration is the loss of water from the plant through evaporation at the leaf surface. It is the main driver of water movement in the xylem. Transpiration is caused by the evaporation of water at the leaf–atmosphere interface. Up to 90 percent of the water taken up by roots may be lost through transpiration as only a small amount of that water is used for growth and metabolism.

Which type of mutation reverses the direction of parts of a chromosome?
Deletion
Duplication
Inversion
Translocation
Answer:
Its "C" Inversion
Explanation:
I took the test and got it correct
Type of mutation reverses the direction of parts of a chromosome is inversion. The correct answer is option C.
What is the basic structure of chromosome ?The chromosomes are thread like structures present in the nucleus and the these chromosomes carry the genetic information in them from one generation to another.
Inversion inverts the structure of chromsome and it basically turns the chromsomes inverted.
Inversion is the process where one arm of the chromosome gets detached from the basic structure and it gets attached in the inverted direction.
This creates multiple copies of DNA turning it into genetic material and one of the X linked recessive disorders is haemophilia in which same type of mutation caused by the chromosome at the 8th position takes place.
Therefore, Mutation that reverses the directions of the part of the chromosome.

How does the anatomy of mitochondria allow it to do
cellular respiration?
Answer: Mitochondria have an important role in cellular respiration through the production of ATP, using chemical energy found in glucose and other nutrients.
What is the relationship between photosynthesis and cellular respiration?
Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose.
Explanation:
Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

Describe how gravity is associated with many erosional agents.
Answer:
Gravity is associated with many erosional agents, because the force of gravity tends to pull all material down the slope. is when a rill channel evolves to become deep and wide. glaciers are dense so they can carry large rocks and debris for a long distance.
Role of gravity in erosion, because gravity tries to draw everything down the slope, gravity is linked to numerous erosional agents.
What are erosional agents?Glaciers and running water both erode due to gravity. This is a result of gravity pulling water and ice downward. These are examples of indirect effects of gravity on erosion.
Due to the force of gravity, mass movement is an erosional process that carries rocks and sediments down slope. The material is moved from higher heights to lower elevations, where it can be picked up and moved to even lower levels by other carrying mechanisms like streams or glaciers.
Therefore, glaciers and running water both erode due to gravity. This is a result of gravity pulling water and ice downward. These are examples of indirect effects of gravity on erosion.

Which selection from the article "Scientists study Persian Gulf reefs for coral survival clues" identifies the biggest threat to coral reefs?
Question 5 options:
Warming waters spark bleaching events. Along with the bleaching, the ocean is becoming more acidic.
The researchers demonstrated that this new organism was the most commonly found algae throughout the gulf's coral reefs. They say it probably adapted as a result of the gulf's harsh conditions.
Warm and acidic water leads to bleaching of coral reef and the new algae can survive due to mutation in its gene.
The biggest threat to coral reefs in the Persian gulf is the warming of waters due to climatic change as well as acidification of water. Algae present on coral reefs can't tolerate acidic water as well as warm water which leads to the death of algae and the coral looks white or colorless.
A new organism was the most commonly found algae throughout the gulf's coral reefs due to change in the genetic makeup due to harsh climatic conditions so we can conclude that warm and acidic water leads to bleaching of coral reef and the new algae can survive due to mutation in its gene.

What does RNA have that DNA does not ?
Answer:
The major difference between DNA and RNA is that DNA is double-stranded and RNA is single-stranded. DNA is responsible for genetic information transmission, whereas RNA transmits genetic codes that are necessary for protein creation. DNA is a long polymer with deoxyriboses and phosphate backbone. Having four different nitrogenous bases: adenine, guanine, cytosine and thymine. RNA is a polymer with a ribose and phosphate backbone. Four different nitrogenous bases: adenine, guanine, cytosine, and uracil.

Peter is 20 months old, weighs 28 lb, and he wants to eat the same food his older brothers do. No baby food for him; he is a big boy now! His mother is worried that this might not be an appropriate diet for a toddler and asked you, the nutrition student, to check it out. Be prepared for a challenge! It’s not easy to think about all the elements that make a healthful diet at the same time. You have to think about kilocalories, Acceptable Macronutrient Distribution Ranges (AMDR, which by the way are different for toddlers than for adults and adolescents), and watch iron (the most common dietary deficit in toddlers) and fiber intake. And that’s just the beginning. Adequate intake of fluids and electrolytes is also critical for a toddler’s health. Is your head spinning already? Let’s simplify the job by approaching each of the recommended Daily Values separately.
A balanced diet helps to prevent malnutrition in all of its manifestations as well as a number of noncommunicable diseases (NCDs) and illnesses throughout the life course.
What is Diet?However, there has been a change in dietary patterns as a result of increased production of processed foods, growing urbanization, and changing lifestyles.
Nowadays, individuals eat more meals that are heavy in calories, fats, free sugars, and sodium/sodium, and many people eat insufficient amounts of fruit, vegetables, and other dietary fiber-rich foods like whole grains.
Depending on individual characteristics (such as age, gender, lifestyle, and level of physical activity), cultural context, regionally accessible foods, and dietary habits, a diversified, balanced, and healthy diet will take on different compositions.
Therefore, A balanced diet helps to prevent malnutrition in all of its manifestations as well as a number of noncommunicable diseases (NCDs) and illnesses throughout the life course.
