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.

can humans perform osmosis?
Answer:
Osmosis is the movement of water from areas of high concentrations to lower concentrations across a semi permeable membrane. It occurs over these membranes in cells of the body alllowing water to move into and out of them.
Explanation:
Early during development, organisms as diverse as a human, a mouse, and a bat can appear indistinguishable. All of their embryos look nearly identical,
suggesting that
this is a coincidental resemblance between them
during development, humans go through stages of being a mouse and a bat
these very different species have a shared ancestry with all mammals

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.

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
Homeostasis can require the control of many different variables in organisms. Homeostasis regarding internal body temperature is very important for many organisms. How is this different among ectotherms and endotherms?
Answer:
The term homeostasis refers to balance, where an organism seeks to maintain the balance of the temperature of its organism in order to persist in life.
There are organisms that are considered ectotherms, with which they release heat to the external environment in order to balance said increase in temperature and not denature their own proteins (such as enzymes, structural proteins, receptors, second messengers, etc.). On the other hand, in the case of endotherms, take energy from the medium to increase your body temperature and maintain it, since otherwise you could enter hypothermia.
In the human organism these principles occur both, not simultaneously, but according to the external temperature in which the human is, ectothermic / catabolic processes in heat stages and endothermic or anabolic processes in the cold stage.
Explanation:
In simple words, endotherm is the heat taken from the medium and exotherm or ectotherm is the release of heat to the medium.
This is so simple in objects, but in living organisms these processes have a reason, and that is why we explained above, when looking for a constant temperature these processes are responsible for mediating balance.
Describe how C. parvum obtains the glucose it needs for glycolysis after it has infected another cell. Explain the role of lactate dehydrogenase in enabling C. parvum to continue producing ATP by glycolysis.
Answer:
Cryptosporidium parvum is an apicomplexan pathogen that obtains glucose either directly from its host or by the degradation of polysaccharides.
Explanation:
C. parvum only can produce ATP by glycolysis. Lactate dehydrogenase (LDH) is a universal enzyme required to synthesize pyruvate, which is the final product of the glycolysis process. This enzyme has been subject of research to understand the metabolism and evolution of apicomplexan parasites, including C. parvum.
Cryptosporidium parvum is a pathogenic agent that causes the disease cryptosporidiosis. The pathogen obtains glucose directly from the host. It can also obtain by the breakdown of polysaccharides.
C. parvum produces ATP through glycolysis. The enzyme lactate dehydrogenase is used by the C. parvum to generate metabolic ATP. It generates this ATP through the glycolytic pathway. The enzyme allows the conversion of NADH to NAD+. NAD+ is necessary for glycolysis to produce ATP. Metabolic energy plays a crucial role in the growth and proliferation of the pathogen in the host.
Some of the features of C. parvum are:
It consists of a unique lactate dehydrogenase enzyme to yield ATP. It causes the disease in the gastrointestinal tracts. The pathogen is used for research and understand its ability to obtain ATP directly from the host.Therefore, C. parvum consists of enzyme lactate dehydrogenase that helps in energy production through the glycolytic pathway.

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.
How do fungi benefit trees?
Answer:
Some fungi help trees and other plants to grow. Because the fine threads that make fungal mycelium can spread over long distances, fungi can capture water and nutrients from far away and bring them back along the fine threads and close to plant roots.

Explanation:
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

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.
