What happened to North American coastal waters when the great white shark population decreased
If North American coastal waters when the great white shark population decreased then planktivore fish number increases.
What happens to marine systems when shark numbers decline?In the Ecosystem, the spatial controls and abundance, sharks indirectly maintain the seagrass and corals reef habitats. The loss of sharks has led to the decline in coral reefs, seagrass beds and the loss of commercial fisheries.
Thus, the number of planktivore fish increases.

18) What kind of mutation causes extensive damage in the DNA?
a. Point mutation c. Frame shift mutation b. Chromosomal mutation d.Nonsense mutation
Answer:
c. Frame shift mutation.
Explanation:
Frame shift mutation is a type of mutation which causes more damage to the DNA of the cell. It causes changes in the amino acid sequences in a polypeptide chain. Point mutation is a type of mutation in which only one amino acid changed, while on the other hand, frameshift mutation changes the whole sequence of amino acids so we can say that frame shift mutation is more damaging to the DNA molecule.

b) Explain why a leaf cannot be tested for starch by adding iodine solution directly.
Answer:
Due to presence of waxy layer.
Explanation:
A leaf cannot be tested for starch by adding iodine solution directly because waxy cuticle covering the leaves that prevents the penetration of iodine in the leave cells. First, the waxy layer should be removed by boiling the leaves that causes disruption in the cell membranes that make easier for the iodine to penetrate in the leave cells so that's why iodine can not be tested for starch directly.

Proteins are a type of biomolecule with a wide variety of functions. Which statement is correct about the digestive system and proteins?
Question 1 options:
Enzymes in your saliva start breaking down the carbohydrates in food
Ready to use energy is released as the protein is broken down
The large intestine absorbs proteins for use in cells.
The liver manufactures bile salts that help break down fats in proteins
Answer:
Enzymes in your saliva start breaking down the carbohydrates in food
Explanation:
It makes sense, your digestive system consists of your mouth, esophagus, stomach, pancreas, liver, gallbladder, small intestine, large intestine, and anus. As soon as you put food in your mouth you break down your food. Also I took the test, hope you make an good grade!!!
The statement 'enzymes in your saliva start breaking down the carbohydrates in food' is correct about the digestive system and proteins.
The digestive system is an organ system where organs work together to digest foods.Enzymes are specific proteins that carry out specific chemical reactions.Digestive enzymes such as amylase are secreted by the salivary glands in order to help with the digestion of foods.
In conclusion, the statement 'enzymes in your saliva start breaking down the carbohydrates in food' is correct about the digestive system and proteins.

like animals plants need continuously reproduce themselves?
Explanation:
Plant reproduction is important to people and animals also because if plants were not continuing to make more of themselves then there would not any plants for people and animals to eat. ... Plants and animals and plants and pollinators are interdependent because they all need each other to survive.
Answer:
like animals plants reproduce by there parent plant from seeds there is three ways plants reproduce from wind, water and animal
animals: animal like monkey eat the fruit of the plant and throw the seed away later it will start growing
wind: when a strong winds occur it will carry plants like dandelions, swan plants away from its parents and when the wind is over it will start growing
water: plants like coconut will fall on the sea and plot away from its parent and after it landed on land it will start growing

When evaluating the viruses that had infected these hosts the previous year, she identifies a cross-species transfer from pigs to ducks in the year 2022. What information supports the hypothesis that cross-species transfer leads to more severe disease in the new host
Answer:
pigs suffered severe influenza in the year 2022
Explanation:
Influenza, commonly known as flu, is a viral infectious disease caused by different types of influenza viruses. Some of the most common symptoms of this disease include, among others, headache, coughing, fever, muscle pain, etc. Influenza viruses can affect humans and different animals such as, for example, cats, dogs, birds and horses. There is evidence showing cross-species influenza virus transmission. For example, it has been shown that the influenza type A virus can be transmitted from one species to another (for example, between humans and pigs). In these cases, cross-species transmission information may indicate how much potential a virus has to cause a pandemic in the new host by analyzing the severity and infectivity of the virus in the original host.

Which sequence of events best describes the current theory of the origin of life on Earth?
Answer:
Development of simple bacteria --> RNA formation --> DNA formation
Explanation:
The sequence of events best describes the current theory of the origin of life on Earth development of simple bacteria --> RNA formation --> DNA formation.
What is RNA?According to the hypothesis and researchers, it seems to confirm that RNA was the first genetic or hereditary material that was present in the simple form of bacteria developed first.
RNA is the molecule responsible for the origin of life on the earth and evolved all the required processes and methods for carrying and expressing the genetic information of an organism before DNA. DNA is evolved from RNA molecules of simple bacteria.
Nucleic acid is one of the biological molecules in living organisms. The two types of nucleic acids are DNA and RNA. DNA (deoxyribonucleic acid) is a double stranded biological molecule that stores genetic information in living cells. They are made up of monomers called nucleotides.
Therefore, The sequence of events best describes the current theory of the origin of life on Earth development of simple bacteria --> RNA formation --> DNA formation.
