Identify the types of breezes and the areas of high and low pressure that cause them.
Answer:
There are 4 types of breezes: land breeze, sea breeze, mountain breeze and valley breeze.
The breeze will originate from an area of high pressure and travel towards/blow in the direction of the area at a lower pressure.
In each case, the name of the breeze indicates where the breeze is blowing from. For instance, the land breeze will blow from the land (at high pressure) to the sea (at lower pressure). A mountain breeze will blow from mountain (at high pressure) towards the valley (at low pressure).

the diagram shows three steps in the clotting process.
Which lists the clotting process in the proper order?
o А, С, В
ОВ, А, С
o С, А, В
е В, С, А
Answer:
В, С, А
Explanation:
The process of clotting is known as the hemostasis which takes place in three steps: the vascular spasm, the formation of a plug of platelets and the coagulation.
In the given question, step B shows the process of vascular spasm in which the vascular blood vessels becomes constricted due to injury. After this, the platelets present in the blood starts accumulating at the site of injury. These platelets stick together and form a plug-like structure at the site of injury.
Later, step A takes place that is fibrin protein present in the blood starts forming a mesh-like structure which does not allow the bleeding and this process is known as coagulation.
Thus, the selected option is the correct answer.
Because the fish are now able to swim in deep water, their ___________ in shallower water will have less food. Likewise, competition for food among deep-water fish that eat the same types of food will _____________.
Answer: Predators, increase
Explanation:
Because the fish are now able to swim in deep water, their Predators in shallower water will have less food. Likewise, competition for food among deep-water fish that eat the same types of food will increase.
Predation is the biological term used to describe the interaction between organisms whereby one organism which is a Predator kills and devour another organism which is its prey.
In shallow waters, Fishes are more susceptible to predators like man, eagle etc who catch and kill them and because of that many of these fishes have acquired anti--predator adaptations to prevent being caught and killed and so are now able to swim in deep waters leading to the predators having less food. The fishes who can now swim deep into waters will increase the already populated deepwater and will cause an increase in competition for the fishes that eat same type of food with the new fishes
Your friend has a dog with fleas. She goes to the pet store and buys over-the-counter flea medicine. It does not work. So she goes to the veterinarian and explains that she just spent $80 on medicine that does not work. The vet casually says, “Oh yeah, that medicine does not work anymore.” Because you now understand natural selection, your friend asks you questions. Answer them with evidence.
- What do the resistant fleas do that the sensitive fleas do not?
Answer:
Explanation:
The dog has fleas, but the medicine to counter this does not work. This means that the fleas have built up a resistance against the drug to ensure continued survival and reproductive success of these organisms. These resistant fleas may have existed in population as the population is always large but in small amounts. Thus, treatment with the drug will lead to the dieing out of the sensitive fleas and then leaving the resistant fleas with the favourable alleles to be selected for.
These favourable traits that have evolved against the drugs are then selected for and the organisms reproduce giving rise to more fleas with these favourable characteristics (being resistant to the drugs) such that their continued survival and reproductive is ensured compared to the sensitive fleas that die out.

Explanation:
Polycythemia is a disease which causes an excessive number of red blood cells to be produced. The disease is the result of a faulty gene. How would the flow of blood be affected by this condition?
Answer:
The blood flow would be delayed, since the amount of red blood cells increases the total density of blood volume, which is why the greater the quantity of blood, the thicker the blood will be.
This, as a consequence, could cause thickening of the blood, thus becoming denser, affecting the continuous laminar flow inside the blood vessels, this means that the flow is not unidirectional, but when it is delayed, it produces a kind of micro whirlpools that hinder healing, circulation, oxygenation and stimulate the appearance of deep and superficial clots or thrombosis.
Explanation:
It is important to clarify that the polycythemia which we are talking about is very excessive, very noticeable, unlike the physiological polycythemia that the body does when faced with an increase in height and a decrease in partial pressure of oxygen.
This is important for you to know, because the body when we climb a mountain or climb, or the partial pressures of oxygen decrease in the atmosphere, takes as a compensation mechanism the increase of red blood cells to maintain the oxygenation of the body, but this being PHYSIOLOGICAL is not excessive.
Polycythemia due to genetic failure such as the one we are writing now is a pathology because we are facing an excessive EXCESS of red blood cells, where phenomena of jaundice and hemolysis can also occur due to the great imbalance that is generated in the entire body
What are some types of biotechnology??
Answer and Explanation:
There are a few different types of biotechnology.
One is medical biotech. Essentially, this branch is used to help improve the wellbeings and helaths of people. It involves a lot of DNA in helping to find cures for various diseases. Some examples of advancements in this field are vaccines and antibiotics.
Another is agricultural biotech. In the agriculture industry, farmers are continuously searching for ways to increase crop yield and quality, which delves into the topic of genetic modification and engineering. For example, scientists are breeding certain plants or adding certain genes to make offspring that is hardier and more pest-resistant.
Those are two main types of biotechnology.
In the gradualism model, species change _____ over time. Evidence for intermediate changes in species' characteristics is_____ . In the punctuated equilibrium model, changes can be rapid followed by periods ______of change. Evidence for intermediate changes in species' characteristics is _____
Answer:
In the gradualism model, species change slowly over time.
Evidence for intermediate changes in species' characteristics is anagenesis.
In the punctuated equilibrium model, changes can be rapid followed by periods of steady change.
Explanation:
Gradualism theory states that the evolutionary processes imply slow, uniform and gradual transformations. This type of evolutionary theory is referred to as anagenesis, where branches are not observed during the evolution of populations. On the other hand, the punctuated equilibrium theorizes that the evolutionary processes are characterized by sudden modifications that are followed by periods without changes. It is likely that both processes may drive evolution of species.
Answer:
gradually, present, little, absent.

Q. Describe the double circulation in human beings.
Answer:Double circulation has two components, pulmonary circulation and systemic circulation. Pulmonary Circulation : It is movement of blood from heart to the lungs and back. Deoxygenated blood of the body enters the righ auricle, passes into righ ventricle which pumps it into pulmonary arch,...
Explanation:
Answer:
During a single cycle blood goes twice in the heart which is known as double circulation. It is necessary in human being to separate oxygenated and de-oxygenated blood because this makes their circulatory system more efficient and helps in maintaining constant body temperature. During a single cycle, the blood goes twice in the heart. This double circulatory system is important because it ensures provision of oxygenated blood to the muscle and not a mixture of oxygenated and de-oxygenated blood. Hence, this system ensures efficient supply of oxygenated blood to the muscles.

Explanation:
A father has blond hair. A mother has black hair. Their three offspring have brown hair, blond hair, and red hair, respectively. Which pattern of inheritance could account for human hair color? Explain your answer.
Answer:
polygenic inheritance
Explanation:
The pattern of inheritance that could account for human hair color according to the illustration is polygenic inheritance.
In polygenic inheritance, multiple alleles (the alternate versions of the same genes) controls the trait for hair color. Individuals that inherit different combinations of alleles from the same parents will have different hair colors.
In this case, there are alleles that determines blond hairs, black hairs, brown hairs, and red hairs. All these alleles are alternate versions of the same gene. The father could be carrying blond/brown alleles and the mother is carrying black/red alleles or vice versa, their offspring will exhibit different hair color depending on which allele is dominant or recessive.
Describe the sequence of events during a blood clot.
Answer: Hemostasis includes three steps that occur in a rapid sequence:
Explanation: 1) vascular spasm, or vasoconstriction, a brief and intense contraction of blood vessels; (2) formation of a platelet plug; and (3) blood clotting or coagulation, which reinforces the platelet plug with fibrin mesh that acts as a glue to hold the clot.
or:
The Blood Clotting Process
Injury. A small tear in a blood vessel wall (for example, from a cut on the skin or an internal injury) causes bleeding.
Vessel constriction. To control blood loss the blood vessel narrows (called constriction), thus limiting blood flow through the vessel.
Platelet plug. ...
Fibrin clot.
Describe how the carbon cycle transfers matter between organisms and their environment. Include three examples. For each example identify which of Earth's spheres (hydrosphere, geosphere, atmosphere, and biosphere) are involved in the exchange of carbon.
Answer:
Crabon is consumed by plants to produce food and taken by other organism as food from plants. They release then CO2 either through respiration or when they die. During this entire chain, carbon moves through all the spheres of earth
Explanation:
Carbon constitutes the base of life on earth. Carbon and its compound regulate between the different spheres of earth to sustain the ecosystems and flow of nutrients and energy.
Carbon is exchanged between all the hemisphere i.e biosphere, geosphere, hydrosphere and atmosphere. For instance – The ocean consists of largest reserve of carbon on earth (part of hydrosphere), Terrestrial biosphere comprising of non-living organic materials and fresh water sources as sink of carbon in biosphere. The sediments and soils consists of carbon (geosphere) and atmosphere consists of a large amount of gaseous carbon dioxide.
Plants take in gaseous carbon dioxide and produces food that stores in it or is consumed by other living organisms. When these organic animals or plants die eventually, they release the solid carbon contained within them either in the geosphere, biosphere or hydrosphere.

Explanation:
How was bipedal locomotion important to hominin evolution?
Answer:
Bipedalism freed the hands so they could be used to cart food, make and use weapons and other advantages of freed hands. Bipedalism is a much more efficient way to walk and run and this fact is quantified. Bipedalism raised the early proto-human above the horizontal so he could see predators approaching. Bipedalism is a much more efficient design to cool down overheating bodies.
