Answer: The endocrine system consists of Glands.
The glands that make up the endocrine system produce chemical messengers called hormones that travel through the blood to other parts of the body. Important endocrine glands include the pituitary, thyroid, parathyroid, thymus, and adrenal glands.The endocrine system is made up of the endocrine glands that secrete hormones. Although there are eight major endocrine glands scattered throughout the body, they are still considered to be one system because they have similar functions, similar mechanisms of influence, and many important interrelationships.14.

Fatty acids from ols present in fish Diet adequate in synthetic form of folate Diot rich in fiber Diot low in sodium and high in potassium Reduced risk of neural tube Reduced risk of hypertension Reduced risk of defects and stroko cardiovascular disease Roduced risk of some types of cancer
Answer:
Reduced risk of neural tube defects- diet adequate in synthetic form of folate Reduced risk of hypertension and stroke- diet low in sodium and high in potassium Reduced risk of cardiovascular disease- fatty acids from oils present in fish Reduced risk of some types of cancer- diet rich in fiberExplanation:
As you may already know, the adequate intake of certain nutrients is very beneficial to our body and to improve and maintain our health. That's because these nutrients act in the construction of essential molecules to keep our body functioning in a healthy and adequate way. Among the numerous nutrients necessary for our health, we can mention that the adequate intake of folate has the ability to reduce the creation of possible defects in the neural tube, while a diet rich in potassium can reduce the risks of hypertension, especially if accompanied by a low sodium diet. Following this same reasoning, a diet rich in fiber can reduce the risk of cancer, in addition to promoting good bowel function. Last but not least, a diet rich in fatty acids from fish can reduce cardiovascular disease.
What do populations living at high elevations have to adapt to?
A) lower ultraviolet light intensity.
B) higher average temperatures.
C) lower oxygen levels.
D) higher heart rates among children.
Answer:
c lower oxygen levels
Explanation:
the higher up the person is the closer to the atmosphere so there is less oxygen
The populations living at high elevations have to adapt to lower oxygen levels because at the sea level they at high altitude, there is less oxygen in the air that we breathe. This results that all of the blood from all areas of the lungs, is proportionally short on hypoxic.
What is hypoxia?
Hypoxia is refer to as the condition of the body in which the tissues are starved of oxygen. In its extreme form, where oxygen is entirely absent, the condition is known as anoxia.
The pressure on the body is about the same as ten meters of sea water pressing down on person body all the time. At sea level, air is compressible, then the weight of all that air at height compresses the air around us, making it denser. As the we go up a mountain, the air becomes less compressed and becomes thinner.

The number of ducks in a pond is equal to the square root of the number of fish, and the number of turtles is equal to the cube root of the number of fish. The number of fish in the pond is more than 1 but less than 100. There are no fractional or negative numbers of ducks, fish, or turtles.
Answer:
There are 64 fish, 8 ducks and 4 turtles.
Explanation:
From the question, there can be from 2 to 99 fish in the pond. However, there cannot be fractions in the number of fish, ducks or turtles. Hence, the number of fish must have both of a perfect square and perfect cube. The perfect squares from 2 to 99 are 4, 9, 16, 25, 36, 49, 64 and 81. The perfect cubes from 2 to 99 are 8, 27 and 64. Since only 64 fits both criteria, the number of fish is 64. The number of ducks is the square root of number of fish, which is the square root of 64. The square root of 64 can be either positive 8 or negative 8. However, there cannot be negative numbers, so there are 8 ducks in total. The number of turtles is the cube root of the number of fish, which is the cube root of 64 and it is 4.
plant reproduction requires the presence of auxins, as well as a large amount of sugar for energy. which two main plant tissues work together to release sugar and carry hormones so that reproduction can take place?
Answer:
The two main plant tissue that works together to release sugar and carry hormones so that reproduction can take place are: The ground and the vascular tissue.
Explanation:
The two main plant tissues that work together to release sugar and carry hormones so that reproduction can take place are Xylem and phloem.
What do you mean by Hormones?Hormones may be defined as a chemical delivered by endocrine glands and discharged into the blood and fascinated to a distantly located target organ.
Xylem is responsible for the transportation of water from the ground to the stem via roots, while phloem, the vascular tissue responsible for the transportation of dissolved sugar from the leaves to the other parts of the plants.

5) The following picture is of a single organism that has been Gram stained and is viewed under oil immersion on the compound light microscope. What is the reason for a single organism appearing like this after being Gram stained
Hi. You have not submitted any images about the microorganism the question refers to. This makes it impossible for me to answer your question. However, I will try to help you as best I can.
Gram stain is a test done to find out whether the bacteria are gram negative or gram positive. In this test, the bacteria are submitted to a certain type of dye and then are observed under a microscope. If the bacteria is gram positive, it will be purple in color. If the bacteria is gram negative, it will be red in color.
This is because after they are subjected to the violet dye, both types of bacteria absorb the color of the dye. However, before being observed under the microscope, the bacteria are washed with alcohol. Alcohol removes the dye from the gram negative bacteria, leaving them reddish. On the other hand, in gram positive bacteria, alcohol dehydrates the cell wall, compressing the pores and making the cell wall impermeable, preventing the dye from being released and, therefore, leaving the bacteria with a purple color.

Manatees and seals both share some phenotypic similarities that are adaptations to an aquatic environment. However, seals evolved from a bearlike carnivore and manatees evolved from a hoofed mammal. This example shows that __________.
a. evolution is not always unidirectional.
b. evolution can occur rapidly for one species while the other species stays relatively unchanged.
c. similarity is a good predictor of how long it has been since two species shared a common ancestor.
d. evolution is not always divergent.
They are about as different as a leopard and a cow.
Meaning both are mammals of roughly similar size, and sharing a vaguely similar habitat. That’s the end of similarities.
Seals are carnivorous and manatees are plant eaters, and taxonomically they are in different orders. Seals spend much of the time on land, while manatees are completely aquatic. Seals have thick layer of fat and are adapted to Arctic water, while manatees, despite their roly-poly appearance, have almost no fat and do not handle cold water well at all. Here is the closest a manatee ever gets to an iceberg.

Carbonic anhydrase is an enzyme found in the cytoplasm of a cell. You genetically modified the gene which produces the mRNA for carbonic anhydrase to now include a signal sequence. What will happen when carbonic anhydrase initially binds to a ribosome
Answer:
Explanation:
Carbonic anhydrase modification is a promising strategy for improving the potency and stability of carbonic anhydrase, which is used to expedite CO2 uptake from flue gases. Carbonic anhydrase can be genetically engineered to increase CO2 conversion, absorption of CO2 from a gaseous state into bioactive compounds, and mineral synthesis.
When carbonic anhydrase attaches to a ribosome, the carbonic anhydrase will now be synthesized at first by the free ribosome, after which the ribosome will become a bound ribosome and the protein will be present in the rough Endoplasmic reticulum when the synthesis is complete.
In this case, when carbonic anhydrase initially binds to a ribosome - Carbonic anhydrase initially will be synthesized by free ribosomes, but then these ribosomes then will become bound ribosomes and the protein will be in the rough ER when synthesis is complete
Carbonic anhydrase is an enzyme that helps the rapid conversion to carbonic acids from carbon dioxide and water with protons and bicarbonate ions.
Classified as a metalloenzymeThe modification in the carbonic anhydrase enhances the potency and stability of the enzyme.It can be modified to increase CO2 conversion, absorption of CO2 from a gaseous state into bioactive compounds, and mineral synthesis.Thus, In the case of carbonic anhydrase bound to a ribosome, at first, the carbonic anhydrase will be synthesized by the free ribosome and later the ribosome will become a bound ribosome and the protein will be present in the rough Endoplasmic reticulum once the synthesis process completes.

PLEASE HELP ASAP!! How neurotransmitters carry nerve impulses across the synaptic cleft
Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron. Neurotransmitters bind to the membrane of the dendrite. The binding allows the nerve impulse to travel through the receiving neuron
Another way of thinking is
Neurons talk to each other across synapses. When an action potential reaches the presynaptic terminal, it causes neurotransmitter to be released from the neuron into the synaptic cleft, a 20–40nm gap between the presynaptic axon terminal and the postsynaptic dendrite (often a spine)
Hope this helps =)
