Answers

Answer 1

Answer:

during exercise there is an increase in physical activity and the muscle cells respire more than they do when the body is at rest

Explanation:

the heart rate increases during exercise as well as the rate of breathing, this makes sure that more oxygen is absorbed into the blood and more carbon dioxide is removed from it

Why do cells hold chromosomes?

Answers

There the DNA is organized in individual chromosomes in the form of very long filaments.Therefore, to ensure safe transport of DNA during cell division the long and coiled DNA fibers must be tightly packed.
Chromosomes are the genetic information that is contained by the nucleus (in some cells) and without chromosomes cell division would not occur

Describe the sequence of events during a blood clot.

Answers

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.

Answers

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.

Which lists the clotting process in the proper order?
o А, С, В
ОВ, А, С
o С, А, В
е В, С, А​

Answers

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.

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.

Answers

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.

Drag each label to the correct location. Each label can be used more than once.

Identify the types of breezes and the areas of high and low pressure that cause them.

Answers

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).

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?

Answers

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.

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 _____

Answers

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.

Explanation:

I just did it on Savvas/Pearson and it was 100% correct.

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 _____________.

Answers

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

Food molecules such as proteins cannot be absorbed unless they are digested.
Give one reason why.

Answers

Answer:

Your body can't absorb proteins in their natural state. Certain proteases in your stomach and pancreas break the bonds that hold the amino acids in protein together so your body can absorb the composite amino acids individually.

Food molecules cannot be absorbed unless digested because ; They are too big to pass through the plasma membrane, in their natural state.

The food molecules such as protein needs to be broken down into its composites amino acids for easy absorption. food molecules, cannot be absorbed in their natural state because they are too big to pass through the plasma membrane.

Protein is broken down ( digested ) by proteases and pancreas into composite amino acids that is absorbable into the human cells.

Hence we can conclude that protein cannot be absorbed unless digested because they are too big to pass through the plasma membrane, in their natural state.

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.
