What type of weather does a H pressure system bring to an area? *
O wet and cloudy
O Dry and cloudy
O clear skies and sunny
O Hot and Sunny
✧･ﾟ: *✧･ﾟ:* *:･ﾟ✧*:･ﾟ✧
✅ Clear skies and Sunny.Explanation: ❗ Cold air is denser and thicker than warm air, so it usually sinks as warm air increases. Cold air sinks which causes a transient accumulation of water near the earth's area and thus an area with a high pressure in regions where winds meet at high altitude. With an increase in altitude air pressure reduces, so high pressure is in fact a relative concept. Weather forecasters commonly use this to signify high pressure relative to normal atmospheric pressures at that level.

Which 3-carbon molecule is one of the final products of glycolysis? (1 point)
oxaloacetic acid
NAD+
O pyruvic acid
O ADP
Answer:
pyruvic acid
Explanation:
Glycolysis involves the breaking of glucose molecule into two molecules of a 3-carbon compound called pyruvate (pyruvic acid) & two other molecules of ATP
Through a sequence of processes known as glycolysis, glucose is divided into two pyruvate molecules, each of which has three carbons. Thus, option C is correct.
What is the significance of glycolysis?Glycolysis is the metabolic process by which glucose produces cellular energy, glycolysis is significant.
The most crucial source of energy for all living things is glucose. Most cells in the human body prefer glucose as a fuel because red blood cells cannot use anything else.
Most living things engage in some form of glycolysis. It represents the initial phase of cellular respiration.
It is a glycolysis route that results in the partial conversion of pyruvate from glucose. The common mechanism for both aerobic and anaerobic respiration is glycolysis.
Therefore, pyruvic acid is a 3-carbon molecule which is the final products of glycolysis.

What is the answer to this question
Answer:
Tertiary Consumer
Explanation:
The snake is high on the food chain but it still gets eaten by bird (I can't see the name).
The cells in red bone marrow that produce blood platelets are called megakaryocytes, which can be
loosely translated as big nucleus cells. These cells continue to move through the cell cycle, but they
skip mitosis and cytokinesis. Review the steps of the cell cycle. What do you think the result of this
modified cell cycle would be?
Answer:
Limits platelets population.
Explanation:
The result of this modified cell cycle would be the presence of limited population of this cell because no mitosis occurs in these cells. Mitosis is a type of cell division that increases population of the cells. These megakaryocytes are changed into platelets by releasing protoplatelets that break up into a number of smaller and functional platelets. These platelets skip mitosis and cytokinesis process which limits their population in the body.

Answer the following questions:
1.2.1 What problem did the paramedics encounter at the accident scene?
Answer: Paramedics are the medical professionals which perform multitasking in providing medical aid to the patients in the field as well as in the hospital.
Explanation:
Problems encountered by the paramedic at the accidental scene:
1. Major problem is the collection of the blood and other bodily fluids for examination as it is contaminated over spilling on the road.
2. Stabilizing and uplifting of the patient found on accident and curating them to ambulance is a labor consuming task.
3. Some body parts are severely damaged in accidents some of which includes those parts which covers the vital organs like ribs, spinal cord, skull, and pelvis so stabilizing those parts is a risky task for paramedics and can even kill the patient.

The Punnett square for a sex-linked trait is shown. The recessive trait is carried only by the X chromosome. Xr is the recessive allele. Based on the Punnett square, which statement is true?
Xr X
X XrX XX
Y XrY XY
A.
Female offspring have a 50 percent chance of expressing the recessive trait.
B.
Both male offspring will express the recessive trait.
C.
Both female offspring will express the recessive trait.
D.
There’s a 50 percent chance the male offspring will express the recessive trait.
Answer:
D. There's a 50% chance the male will express the recessive trait
Explanation:
Because X is dominant over Xr, a female could not express it in this punnett square because she will have the extra X chromosome. While males do not have the extra X so if they receive the Xr they will have nothing to "cover" them.

Humans, like other organisms, require energy for growth and repair. When cells create ATP for energy, carbon dioxide is produced as a waste product. How does the body respond to this process in order to maintain homeostasis?
Answer:
The circulatory and respiratory systems interact to transport carbon dioxide to the lungs, where it is expelled from the body.
Explanation:
Carbon dioxide produced by the cells and tissues during cellular respiration is removed from the body through the interaction of the circulatory and respiratory system. The medium of transport of carbon dioxide is the blood which carries to the lungs, where it is expelled from the body in ordernto maintain homeostasis in the body.
Carbon dioxide molecules are transported in the blood from body tissues to the lungs in three ways:
1. Dissolution directly into the blood - due to its greater solubility in blood than oxygen, carbon dioxide is dissolved in blood plasma. On reaching the lungs, it leaves the blood by diffusion and is then expelled out of the body.
2. Binding to hemoglobin - carbon dioxide binds reversibly with haemoglobin in the red blood cells to form a molecule called carbaminohemoglobin. When it reaches the lungs, the carbon dioxide freely dissociate from the hemoglobin and is expelled from the body.
3. Carried as a bicarbonate ion - the majority of carbon dioxide molecules are carried as part of the bicarbonate buffer system. In this system, carbon dioxide diffuses into the red blood cells. The enzyme carbonic anhydrase within the red blood cells quickly converts the carbon dioxide into carbonic acid (H2CO3) which then dissociates into bicarbonate and hydrogen ions. The bicarbonate ions leaves the red blood cells in exchange for chloride ions in the plasma. The bicarbonate ions then travel in plasma to the lungs, where they enter the red blood cells again. It combines with hydrogen ions from the haemoglobin to form carbonic acid. Carbonic anhydrase breaks carbonic acid down into water and carbon dioxide which is then expelled from the lungs.
Explain 4 ways that invasive species are spread by humans?
Answer: They may be wind blown, rain splashed, carried by animals, or moved in soil or water. Almost all short-distance spread is through these natural dispersal mechanisms. In their home territory, short distance spread is rarely a problem because the resident plants and animals have evolved to coexist more or less peaceably.
Explanation:
Humans can help in the spread of invasive species.
What is an invasive species?It is a species that is not naturally present in an area ("not native") and when introduced in that area disturbs the ecosystem.For example, Eichhornia crassipes, cane toad, etc.How can human spread the invasive species?Humans can help in the spread of invasive species:
A species is introduced due to its beauty - because of its beautiful flowers and leaf shapes, the water hyacinth was brought to India.It is a contaminant of a species that is introduced - Parthenium is thought to have arrived in India as a contamination in PL 480 wheat from the United States.They may be brought accidentally- Zebra mussels arrived in North America's Great Lakes by accident, clinging to big ships.To control the population of other species - Small Indian mongooses were introduced with the goal of controlling rats that were ruining the sugarcane crop.To learn more about species, invasive species, population and ecosystem here,
