Which pair of microscope views represents a eukaryotic cell and prokaryotic cell?

Answer:

This is Because they can't be 100% in location of PCBs since animals could spread and reproduce among different places with these toxins within their systems.

Explanation:

Answer:

The correct answer is - vestigial structures or organs.

Explanation:

Vestigial organs are structures or the organs are body parts that had once important function but now have no apparent function. These are body parts that look like these are residual parts from a past ancestor.

The hip bone in whales, the leg bone in snakes, and the appendix in humans are thought to have once important functions but now have no apparent function and are vestigial organs.

Answer: Structure of DNA: double-stranded helix held by complementary base pairs. DNA carries the genetic information for making proteins. The four bases A, T, C and G make up the genetic code. The base sequence determines amino acid sequence in protein.

Answer:

Nuclear Energy from uranium is non-renewable

Hydrogen from water is renewable

Wind energy from air is renewable

Solar energy from the Sun is renewable

Fossil fuel from coal is non-renewable

Explanation:

Energy resources refers to those materials or items from which energy can be derived. Energy resources are generally classified into renewable and non renewable energy resources.

Renewable energy resources are those types of resources which can be renewed or replenished as they are being used up. Renewable energy is often referred to as clean energy and comes from natural sources or processes. Examples of these renewable energy resources are energy from wind, water and sunlight.

Non-renewable energy resources are those types of resources which are not easily renewed or replenished as they are being used up. Examples include energy from fossil fuels such as petroleum and natural gas, coal, nuclear energy from radioactive materials, etc.

From the given table:

Nuclear Energy from uranium is non-renewable

Hydrogen from water is renewable

Wind energy from air is renewable

Solar energy from the Sun is renewable

Fossil fuel from coal is non-renewable

Answer:

Selective breeding.

Explanation:

Both are fairly long processes, however, the measurement for this is not just the duration to obtain the target, but also the exact target obtained. In natural selection, the duration may be faster than selective breeding in obtaining a change, but the determined change may not be the one that is sought out for. It may have a small chance, but it is not guaranteed. In selective breeding, on the other hand, the destination is determined, and all steps work towards the objective. So in a sense, selective breeding has the greater percentage chance of being the shorter process.

Answer:

B. Small cells do not require energy and get everything they need from osmosis.

Explanation:

Small cells contain a greater quantity of enzymes than large cells. The cell has a smaller surface area to volume ratio which means it can move nutrients into the cell and waste out more efficiently.

Answer:

C the moom rotates around itself slower than eath rotates around itself

Explanation:

Answer:

There are four principles at work in evolution—variation, inheritance, selection and time. These are considered the components of the evolutionary mechanism of natural selection. After a while the birds will get old and their beaks will get weaker, eventually they will die, when there is a shortage of food they will start harming each other in order for it, that’s selection.

Answer:

c because they need to live instead of dying. bc from other bigger animals they can see it and eventually die so.

Answer:

A unicellular organisms depends upon its one cell for all the functions and survival of the organism. It has all the important characteristics that is necessary for its survival.

Explanation:

A unicellular organism is one which contains only one cell. And so all the life processes occurs in that one particular cell in an unicellular organism. A n unicellular organism is also called as the single cell organism.

The unicellular organisms uses cilia as well as the flagella to achieve locomotion by creating currents around and move about places. The take up nutrients by diffusion process. They reproduce asexually and produce their offspring.

Answer: When a substance is heated, it gains thermal energy. Therefore, its particles move faster and its temperature rises. When a substance is cooled, it loses thermal energy, which causes its particles to move more slowly and its temperature to drop.

Answer: pesticides

Explanation:

Answer:

The working assumption for many years was that, like North American bison, European bison evolved from steppe bison. ... Their results suggest that the European bison is the result of inter-breeding, over 120,000 years ago, between steppe bison and aurochs; the wild ancestors of modern domestic cattle.

Our study suggests that the first bison arrived in North America 195 - 135 thousand years ago over a land bridge between Asia and Alaska. They quickly spread and evolved (changed) into different forms to adapt to their new environments.

Answer:

Humans use up many nonrenewable reacources every day, alongside renewable ones. One example of such is oil, oil takes millions of years to form, much longer than the amount of time it takes for us to use it up.

Populations that experience a logistic growth model depend on the density and available resources. A) 5 - 10 days. B) 25 - 30 days. C) 0.27 x 10⁶cells/mL/day

In a logistic growth model, the population growth depends on density. Natality and mortality depend on the population size, meaning that there is no independence between population growth and population density.

When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate. The population per capita growth rate decreases as population size increases.

The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.

K is a constant that equals population size at the equilibrium point, in which the natality and the mortality rate get qual to each other.

Assuming that the population size is N, when

The sigmoid curve represents the logistic growth model.

In the example,

Time period during which Chlorella,

          A) approximates exponential growth ⇒ Between 5 and 10 days

Between 10 and 20 days its already exponential growth.

         B) has reached the carrying capacity of the culture ⇒ 25 to 30 days

Finally,

        C) Growth rate per day for the 5-day period with the greatest growth rate.

First we need to figure out during which period Chlorella experiences the  greatest growth rate. To do it, we just need to make the following substraction,

Growth rate per period = final concentration - initial concentration

Now we know that during the period from 10 to 15 days, the population experienced its greatest growth rate. But this rate is acchieved in 5 days. Now we need to find out the growth rate per day. So all we need to do, is to divide the result of the substraction per 5 days,

1.35 x 10⁶ / 5 days = 0.27 x 10⁶ cells/mL/day

The answer is 0.27 x 10⁶ cells/mL/day
