What are barrier islands? What protects the barrier islands?
Answer:
Barrier islands form in three ways. They can form from spits, from drowned dune ridges or from sand bars. Longshore drift is the movement of sand parallel to the shore caused by the angle of the waves breaking on the beach. When a storm such as a hurricane digs an inlet through the spit a barrier island is formed. Barrier islands are a specific type of island that lie parallel to the coastline of a larger mainland. They are separated from shore by a bay, lagoon or sound and because of where they are situated, they protect the coast from being directly impacted by storm waves or winds.

Margination refers to the adherence of phagocytes to microorganisms. the chemotactic response of phagocytes. adherence of phagocytes to the lining of blood vessels. dilation of blood vessels. the movement of phagocytes through walls of blood vessels.
Answer:
adherence of phagocytes to the lining of blood vessels
Explanation:
The correct answer for the medical/biological definition of margination would be the adherence of phagocytes to the lining of blood vessels.
Margination is a process that takes place when injuries occur in complex animals. During the early phase of inflammation of the injury site, the blood capillaries dilate and the white blood cells (phagocytes and leukocytes) adhere to the endothelial cells of blood vessels.
Neurogenesis is especially evident in brain areas related to learning and memory. Based on this statement, you might expect neurogenesis to be particularly prevalent in the brain's:
Cortex, especially neo-cortex and pre frontal cortex. Where neuroplasticity can occur.
what is produced from covalent bonding
Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability

What do animal cells need to make energy?
Answer: Eating.
Explanation:
Animals obtain energy by eating plants or animals. The only form of energy a cell can use is a molecule called adenosine triphosphate (ATP). Chemical energy is stored in the bonds that hold the molecule together. ADP can be recycled into ATP when more energy becomes available.
Answer:
Food
Explanation:
Animals obtain energy when they eat. So do we, because we have animal cells! If you don't eat you will get weak and your body needs the nutrients that it gets from the food that you eat. So to make adenosine triphosphate (ATP), you need energy and some other factors that go into making ATP.. but that is the just of it.
You need food.

In 3–5 sentences, describe how carbon dioxide levels can be reduced in the atmosphere.
Answer:
Walk to places as much as possible to reduce co2 emissions from cars.
Explanation:
The levels of carbon dioxide is higher in the atmosphere than it was before because of the human activities, which is eventually leading to global warming. Carbon dioxide being one of the most important greenhouse gases is present in abundant concentrations in the atmosphere and there is a need to reduce the levels to have some relief from global warming.
Some of the ways of reducing the levels of carbon dioxide in the atmosphere are:
• Planting more trees as trees are mainly good at storing carbon by the process of photosynthesis.
• Another way to use photosynthesis to fight against climate change is the use of bio-energy with carbon capture and storage technique. It is the process of utilizing biomass as the source of energy in the power sector.
• Another way to capture carbon dioxide directly from the air is by chemically scrubbing carbon dioxide directly from the ambient air, and then storing it either in the long-lived products or underground.
Thus, there are some techniques, which can be implemented to reduce the concentration of carbon dioxide from the atmosphere.

Answer:
Dopamine
Explanation:
The correct answer would be dopamine.
Dopamine is a chemical messenger produced in the substantia nigra, ventral tegmental area, and hypothalamus of the brain and has a variety of functions, including mediation of pleasure, learning, movements, sleep, etc.
Dopamine is released by the brain during pleasurable situations. The compound also has the ability to inhibit the actions of norepinephrine to make one feels alert and speeds up the activity in the brain.

1.what did magnesium and oxygen atoms had to do to bond ?
2. why did the oxygen atom needed two sodium atoms to bond ?
3. why did the magnesium atom needed two fluorine atoms to bond ?
please put the numbers in order so i know which answer is for the questions thanks <3
Answer:
1. Magnesium and oxygen atoms bond to form an ionic compound; this is evident because one forms a cation and the other an anion. When an ionic compound is formed, one atom "steals" an electron (or electrons) from another. In this case, an oxygen atom (which is pretty electronegative by the way) "steals" 2 electrons from a magnesium atom. The resulting oxygen anion and magnesium cation attract one another to form a bond (more specifically, an ionic one).
2. The oxygen atom needed two sodium atoms to bond because it needs two additional electrons to achieve a stable octet of electrons. 1 sodium atom provides 1 additional electron after it is "stolen" by oxygen, so 2 sodium atoms are needed in total to form the bond.
3. The magnesium atom needed two fluorine atoms to bond because it needs to lose two electrons to achieve a stable configuration/octet of electrons. 1 fluorine atom "steals" one electron, so 2 are needed in total.

The somatic motor division consists of somatic motor neurons that innervate cardiac, smooth, and skeletal muscle cells. The somatic motor division consists of somatic motor neurons that innervate cardiac, smooth, and skeletal muscle cells. True False
Answer: FALSE
Explanation:
The nervous system is the system that detects and responds to changes inside and outside the body. This system consists of the brain, the spinal cord and peripheral nerves. The structure and organisation of the tissues that form these components enables rapid communication between different parts of the body.
Parts of the nervous system includes:
--> Central Nervous System ( consists of the brain and spinal cord)
--> Peripheral Nervous System ( consists of nerves outside the brain and spinal cord).The two functional parts of the peripheral nervous system are made up of the sensory (afferent) and motor (efferent). The motor division is involved in activities that are voluntary (somatic nervous system) and involuntary (autonomic nervous system).
The somatic motor division consists of somatic motor neurons that innervates ONLY the SKELETAL MUSCLE for its voluntary actions while the autonomic motor neurons innervates the cardiac and smooth muscles. Therefore the statement is FALSE

Zara had a birthday and was able to choose a pet. The pet that she chose was a beautiful clownfish named Bozo, a common salt water fish. Zara already has a tank with goldfish at home. Use your knowledge of diffusion & osmosis to tell Zara how to take care of Bozo.
Answer:
See the answer below
Explanation:
Zara should keep Bozo in a separate salt water-containing tank away from the goldfish.
Bozo is adapted to living in salt waters. If it is kept in saltless water like the goldfish, its cells would lyse and the fish may die. The saltless water would be hypotonic to the cells of Bozo and water moves osmotically from a region of high water potential to a region of low water potential. Hence, the cells of Bozo would take-in water, become turgid, and may eventually lyse, leading to the death of the fish.
The goldfish cannot survive in salt water with Bozo because the water would be hypertonic to its cells. Hence, it will lose water to the surrounding salt water due to osmosis and may eventually die of dehydration.

i) predict which of the liquids would cause the largest decrease in mass of potato stick
PLEASE PLEASE HELP ME I HAVE 10 MINUTES ONLY, I WILL GIVE YOU THE BRAINLIEST!!
Answer:
1.0 mol per dm^3 sodium chloride solution
Explanation:
The idea behind this question is that the water inside the potato stick would move into the surrounding liquid naturally if the density outside the stick is greater than it is inside. Therefore, the liquid that would most encourage the flow of water from the potato stick would be the moet dense liquid- which in this case, is 1.0 mol per dm^3 sodium chloride solution.
On one cactus species, the red flowers are dominant over white flowers. If you crossed two heterozygous cacti, what would be the probability of having offspring with red flowers?
Answer:
3/4
Explanation:
This question involves a single gene coding for flower color in cactus plant. The allele for red flowers (R) are dominant over the allele for white flowers (r). This means that a cactus that is heterozygous (Rr) for the Gene will possess a red phenotype.
In this cross, two heterozygous cacti are crossed. The following gametes will be produced by each heterozygous parent: R and r. Using these gametes in a punnet square, the following genotype of offsprings will be produced;
RR, Rr, Rr, and rr
RR, Rr and Rr are Red flowers (3/4)
rr are white flowers (1/4)
Therefore, the probability of having offspring with red flowers is 3/4.
