A marshy area dries up, and most of the organisms in a population of flowers die. However, some of the flowers have adaptations that allow them to survive the change. If the land stays dry, what will the population of flowers be like several generations from now?

A. The population will have greater genetic diversity because the additional stress caused by lower water levels will result in increased immigration.

B. The population will have the same genetic diversity as when the area was marshy.

C. The genetic diversity will be less than in the original population, as more flowers will have the adaptations to live in the drier conditions.

D. The flowers will all die off because they could not survive in the drier conditions.

Answers

Answer:

C

Explanation:

All that is left are the plants capable of surviving in dry conditions; whereas before there were plants that thrived in more marshy conditions. Therefore decreased genetic diversity. The adaptations of the plants will be much less diverse.

An element only has one type of atom and cannot be broken down by chemical means.

Let's analyze the answer choices.

1. This has two types of atoms, so it cannot be an element. It has more than one type of atom.

2. This has two types of atoms that are bonded together. It cannot be an element because there is more than one type of atom and the bonds can be broken.

3. This has one type of atoms, so it is an element.  

Therefore the best answer choice is 3.

- The cane toad has been introduced to some ecosystems to reduce the number of
pests that damage crops. In the areas where they have been introduced, none of the
predators are immune to the protective toxins the toad produces. What is a probable
outcome from the introduction of the cane toad in the following 10 years?

Answers

Answer:

D

Explanation:

The crops will not deplete the soil. The Frog will not lose its toxin because nothing bad comes from that trait. A predator cannot adapt to a toxin in the span of only ten years. The insect population should deplete because the frog should multiply and concur the population of pests since the frog doesn't have any predators.

What challenges do Arctic areas face as a result of global warming? 2) What measures could help deal with the problem? 3) What do you predict will happen to Arctic ecosystems if no measures are taken to reverse the problem of global warming? Explain your reasoning. 4) Which measures do you think are most important to pursue?

Answers

Answer:

Global warming is defined as the environmental issue that leads to long term heating of the earth due to human activities such as burning of fossil fuels.

1. Arctic areas are facing huge challenges due to global warming that includes rising sea levels, rapid melting of ice,  loss of fish stocks, birds and marine mammals, and changes in climate patterns.

2. Measures that help to deal with the problem are reduction in the use of hydrofluorocarbons, cutting emissions of black carbon, methane, reduce overfishing, and reduction of industrial waste.

3. If there will be no measure taken to reverse the problem of global warming in the Arctic ecosystem, it will cause flood and tsunami in the nearby continents due to the rapid melting of ice, changes in climate patterns, and lead to the extinction of many marine animals.

4.  Reduction of industrial waste is the most important measure to pursue because industrial waste contributes most of the greenhouse gases and causes air pollution, land pollution, water pollution, and nuclear pollution. So reduction is industrial waste will reduce the emission of harmful gases in the environment that can reduce the impact of global warming.

Answers

Answer:

Carbon cycle is very important for the plants and animals that are divided into 4 steps and these steps are:

1.The carbon enters the atmosphere in the form of carbon dioxide.Example: respiration and combustion.

2.The carbon dioxide present in the environment is used by the plants and  plants expel oxygen after the process of photosynthesis.

3. Animals present in the environment eat the plants and pass on the carbon in the food chain. They exhale carbon dioxide into the environment.The plants and the animals die after a certain period of time.

4. The body of plants and animals is consumed by decomposes and the carbon is returned into the atmosphere in the form of carbon dioxide else fossils of plants and animals are formed which contains carbon.

deciduous forest Predict which sample would have a greater concentration of organic
material Explain your answer

Answers

Answer:

Temperate deciduous forest

Explanation:

The temperate deciduous forest will have more organic matter concentration in it.

Organic matter is a component of biological relics found in the soil. It makes up a significant portion of the soil.

Soil organic matter should not be confused with biomass production. Rainforest due to its biodiversity is rich in organic biomass. These organic matter decays rapidly due to the humid conditions, and are become lost. Also, the rate of weathering in the rainforest is very high. This often washes and removes organic matter from the soil. These conditions are not so in the temperate forest.

The surface area/volume ratio is an important factor for one celled organisms. As a cell's volume grows, its surface area/volume ratio ______________, making it more difficult to acquire enough nutrients via diffusion. Question 7 options: increases freezes decreases stays the same

Answers

Answer: decreases

Explanation:

The surface area to the volume ratio will decrease as the volume of the cell increases or the cell gets larger. Therefore, if the volume of the cell increases beyond the certain limit the cell will not be able to imbibe nutrients as not enough material can pass through the cell membrane to accommodate the increase in volume of the cell.

Sex-Related inheritance: X chromosome; Non Sex-Related inheritance​

Answers

What we already know:

All species under normal circumstances will have two sex chromosomes. X and Y, Y is known to be dominant. All females will have two X chromosomes (XX, one X will always be given by the mother), whereas males will have one Y chromosome and one X chromosome (XY, one X will always be given by the mother. The father, on the other hand, could give either an X or a Y, that all depends on what sex chromosome the father's sperm donated.)

So, how many chromosomes do a typical human have? Correct, a typical human has 32 chromosomes and only 2 of them are sex chromosomes. Now we must understand that the sex chromosome carries more than just the one code for the individual sex. That means that the gene codes for more than just the sex.

Building on that knowledge:

Sex-Related Inheritance that differs from sex, is carried on one or two of an individual's sex chromosome. Whereas Non-Sex-Related Inheritance is carried on the other thirty chromosomes that the individual also carries.

Sex-Related inherited genes that are passed via the father to male offsprings, carried on the Y chromosome, are easiest to spot in a family. All males will have this trait and no females will.

Non-sex-related inheritance can be passed from male to female and from female to male, this is sometimes harder to differentiate from genes carried on the X chromosome because the mother always gives an X chromosome.

Vocabulary:

phenotype: the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
