Why is food web more practical in nature than food chain
Answer:
Hey mate.....
Explanation:
This is ur answer....
A food web is a more realistic way of portraying an ecosystem than a food chain because food chains imply that organisms only eat one type of organism which is rarely true. In a food chain predators occupy higher levels than their prey. Food webs are more complicated diagrams that are not purely linear.

Which statements accurately describe the pharmacokinetic parameters of oral conjugated equine estrogens (CEEs)
The parameters are near complete absorption, high protein binding, and high distribution, extensive metabolization of tamsulosin, and exit of the substance through the urine, as shown in options 1,3,4, and 5.
We can arrive at this answer because:
Oral conjugated equine estrogens are medications taken orally when prescribed by a qualified practitioner.These medications are made with a mixture of several types of estrogens that resemble each other in some way.They are widely used to treat osteoporosis and other common problems in women.One of the main characteristics and advantages of this type of medicine is that its excesses are eliminated in the urine. In addition, they are easily absorbed by the body, are highly distributed, easily bind to proteins, and are easily metabolized.

You are looking at a stained smear of horse blood and you see a leukocyte with large red granules in its cytoplasm. What cell are you most likely seeing
Looking at a stained smear of horse blood and seeing a leukocyte with large red granules in its cytoplasm. I am most likely seeing a granulocyte, an eosinophil in particular.
Leukocytes are white blood cells and there are various types of white blood cells including granulocytes, agranulocytes.
Granulocytes are white blood cells present with granules and produced in the bone marrow. There are three types of granulocyte; they include eosinophil, basophil and neutrophil.
Eosinophils are white blood cells with large granules and they stain red with dye. Their nucleus is also made up of two unsegmented lobes.

True or false: Theoretically, it is possible (but very difficult) for a population to not evolve for a while.
It is true that it is possible for a population to not evolve for a while.
There is something called the Hardy-Weinberg theorem, which characterizes the distributions of genotype frequencies in populations that are not evolving.
There are 5 Hardy-Weinberg assumptions:
no mutation random mating no gene flow infinite population size and no selection (natural nor forced).You can see that some of these are kinda extreme and really hard to get, but with approximations, we can work.
For example, instead of an "infinite population size" we have enough with a really large population, such that genetic drift is negligible.
Concluding, yes, it is possible (but really difficult) for a population to not evolve for a while (at least, in nature), as long as the 5 assumptions above are met.

Answer:
an insertion mutation in an egg cell that deactivates a gene for hair color, resulting in a viable error
Answer:
Option 4. an insertion mutation in an egg cell that deactivates a gene for hair color, resulting in a viable error.
Explanation:
Only germline mutations are hereditary in nature i.e., that can be passed on from the parent to the offspring. Examples of hereditary mutation include Sickle cell anemia or hemophilia.Germline mutation: Any noticeable genetic changes in the germ cells of the body that is passed on from the parent to off spring.Mutations such as somatic cell mutation, chromosomal mutation, silent mutations are not hereditary.Option 4 talks about the mutation in egg cells i.e., the reproductive cell which affects the phenotypic traits such as hair color. The change in the phenotypic trait means that it is a genetic mutation of the egg cell as phenotypic changes only occur as a result of genetic mutation. Hence, any detectible mutation in the germ cell can pass on from a parent to offspring.For more information:

The world population has surpassed 7 billion and is continuing to increase dramatically. Select the factor that has demonstrated an
inverse relationship to population growth.
es )
A)
deforestation
B)
violent political conflict
spread of communicable diseases
D)
biodiversity of plant and animal species
Answer:
D
Explanation:
As population grows all the above factors increase expect the biodiversity of animal and plant species.
On a basic level, it is obvious that population increase and per capita income growth are related. Per capita income is simply total income divided by the population. Thus, option D is correct.
What inverse relationship to population growth?When attempting to forecast changes in population size, demographers frequently focus on four essential criteria.
The population's starting age profile (whether it is relatively young or old to begin with), migration, and fertility rates (death rates; life expectancy).
Depending on particular environmental factors, two different patterns of population expansion may manifest: In a perfect, limitless environment, an exponential growth pattern (J curve) manifests itself.
The development of a logistic growth pattern (S curve) occurs when external forces reduce the pace of growth.
Therefore, The gap between the growth rates of income and population is roughly equivalent to the growth rate of per capita income.

A 160 lb. college student consumes a bowl of cereal containing 750 Calories in the morning. He then sits quietly in class for 4 hours, and then goes for a 30-minute run. How many Calories did he use, and was it more or less than he consumed?
Answer:
less
Explanation:
because a 30 min run can only burn 200-500 calories
In the morning, a 160-pound college student consumes a bowl of cereal with 750 calories. 30 minutes of running can only burn 200-500 calories.
What is Calories?The calorie is a type of energy unit. For historical reasons, there are two main definitions of "calorie." The large calorie, food calorie, or kilogram calorie was originally defined as the amount of heat needed to raise the temperature of one kilogram of water by one degree Celsius.Calories are the units of energy released by your body when it digests and absorbs food. The higher the calorie content of a food, the more energy it can provide to your body. When you consume more calories than you require, your body stores the excess calories as fat. Even fat-free foods can be high in calories.
