Which of these statements is true of ecosystems? a animals do not travel from one ecosystem to another ecosystem b the total amount of energy in an ecosystem does not change c air cannot be used by organisms once the air moves out of the ecosystems d matter lost by one ecosystem is gained by the surrounding environment
Answer:
I think the answer is B. I think energy decreases as it moves up tropic levels when it is lost as the organisms from one level consume the organisms in the other.
Explanation:
It can't be A because animals do travel from one ecosystem to another. It's migration. It's not C because air can be used by organisms as once as the air moves out of their ecosystem because air is everywhere and the organisms need air to breathe and to live. D is definitely incorrect because matter can't be created or destroyed. Remember that an ecosystem is the organisms physical environment. I hope this answers your question.
D, matter lost by one ecosystem is gained by the surrounding environment
Explanation: Here's an explanation for why D is right and all the other ones are wrong.
D- when matter is lost from one ecosystem, it is often gained by another nearby ecosystem. For example, when leaves fall from trees in a forest, they decompose and release nutrients into the soil. These nutrients can then be taken up by plants in the same ecosystem or be transported by water runoff to other ecosystems, such as rivers or lakes. This process of matter transfer ensures the cycling of nutrients within and between ecosystems.
A- animals can and do travel from one ecosystem to another. Birds migrate between different habitats, and some animals spread seeds or pollinate flowers in multiple ecosystems. B- the total amount of energy in an ecosystem does change over time. Energy enters an ecosystem through photosynthesis, where plants convert sunlight into chemical energy. This energy is then passed on to other organisms through the food chain. However, energy is lost as heat during these transfers and eventually leaves the ecosystem, resulting in a decrease in the total amount of energy available. C- organisms rely on air for respiration, and the exchange of gases, like oxygen and carbon dioxide, occue between organisms and the air in the environment. While air moves in and out of ecosystems, organisms continuously utilize the air for their survival.

Due to its location, Hawaii does not have very many land birds. The Hawaiian honeycreepers are a favorite for many ornithologists. There are over 50 species of honeycreepers that can all be traced back to one ancestor. The level of diversity in an ecosystem can be determined by the frequency of speciation and extinction.
a) Describe speciation and identify two possible prezygotic barriers of the Hawaiian honeycreepers that contribute to speciation.
b) If the Hawaiian honeycreepers became extinct, explain how the newly available niches could lead to speciation.
Answer:
In speciation, organisms evolved with the passage of time.
Explanation:
Speciation is the evolutionary process in which populations of species evolve with the passage of time to become different species from the original one. Temporal isolation and gametic isolation are two possible prezygotic barriers of the Hawaiian honeycreepers that contribute to occur speciation. The newly available niches could lead to speciation of that organisms that tolerate the Hawaiian climatic conditions when the extinction of Hawaiian honeycreepers occurs. The new organisms used the available resources such as food and space etc and increase its population.

A scientist is studying three different plant species that appear to be closely related. All three are found in a wide variety of environments and are very similar in appearance. Which of the following would provide the best evidence regarding the evolutionary relationship of these three species?
Comparing the different climates in which the species can be found
Comparing the genomes of each species to see which are most similar
Determining whether the plants are capable of both sexual and asexual reproduction
Determining which types of animals eat each species
Determining the genomes of each species to see which is similar will provide the best evidence regarding the evolutionary relationship of these species. So the correct option is B.
What are evolutionary relationships?The relationships of different species with each other based on their history of evolution are called evolutionary relationships.
The study of the relationships between organisms by categorizing them into various kinds of groups is called systematics.
All the species of organisms, from bacteria to mammals have evolved from some kind of ancestral species by the process of evolution.
Determination of these evolutionary relationships is the key to understanding the process of evolution. Evolutionary relationships are determined by using evolutionary trees which are diagrammatic representations of ancestral species and their descendants.
The study of genomics to identify the similarity between organisms is yet another useful tool to determine the relationship between them.
Therefore the correct option is B.

Explanation:
A denisty of a bottle weighs 0.25N when empty & 0.75N when filled with water & 0.65N when filled with alcohol. Calculate;. 1) the volume of the bottle 2) the denisty of the alcohol (denisty of water is 1000kg/m & g is 10m
Answer:
[tex]0.05\times 10^{-3}\ \text{m}^3[/tex]
[tex]800\ \text{kg/m}^3[/tex]
Explanation:
[tex]W_b[/tex] = Weight of bottle = 0.25 N
[tex]W_w[/tex] = Weight of water = [tex]0.75-0.25=0.5\ \text{N}[/tex]
g = Acceleration due to gravity = [tex]10\ \text{m/s}^2[/tex]
[tex]\rho_w[/tex] = Density of water = [tex]1000\ \text{kg/m}^3[/tex]
Mass of water
[tex]m_w=\dfrac{W_w}{g}\\\Rightarrow m_w=\dfrac{0.5}{10}\\\Rightarrow m_w=0.05\ \text{kg}[/tex]
Volume is given by
[tex]V_w=\dfrac{m_w}{\rho_w}\\\Rightarrow V_w=\dfrac{0.05}{1000}\\\Rightarrow V_w=0.05\times 10^{-3}\ \text{m}^3[/tex]
Volume of the bottle is [tex]0.05\times 10^{-3}\ \text{m}^3[/tex].
This means that the alcohol will take the same amount of volume.
[tex]W_a[/tex] = Weight of alcohol = [tex]0.65-0.25=0.4\ \text{N}[/tex]
Mass of alcohol
[tex]m_a=\dfrac{0.4}{10}\\\Rightarrow m_a=0.04\ \text{kg}[/tex]
Density is given by
[tex]\rho=\dfrac{m_a}{V_w}\\\Rightarrow \rho=\dfrac{0.04}{0.05\times 10^{-3}}\\\Rightarrow \rho=800\ \text{kg/m}^3[/tex]
Density of alcohol is [tex]800\ \text{kg/m}^3[/tex]
The volume of the bottle is 50 mL and the density of alcohol is 0.8 g/c[tex]m^{3}[/tex]
The weight of empty bottle is 0.25N
the weight of bottle filled with water is 0.75N
therefore, the weight of water in the bottle is 0.75N - 0.25N = 0.50N
we know that weight, w =mg , where m is the mass of substance and g is acceleration due to gravity. Here we will take g= 10 m/[tex]s^{2}[/tex] for simplicity.
⇒ m = w/g = 0.5/10 = 0.05 kg
⇒ mass of water is 50g
now, the density of water ρ(w) = 1g/[tex]cm^{3}[/tex] = 1g/mL
relation between mass, density and volume is:
V = m/ρ = 50/1 = 50mL
Hence the volume of the bottle is 50mL.
Now it is given that the weight of bottle filled with alcohol is 0.65N
⇒ weight of alcohol = 0.40N
⇒ mass of alcohol = 0.40/g = 0.40/10 = 0.040kg = 40g
The volume of the bottle remains the same, so to calculate the density of alcohol we use the above mentioned relation between mass, density, and volume on alcohol.
That is, V = m/ρ
⇒ ρ(al) = m/V = 40/50 g/c[tex]m^{3}[/tex]
ρ(al) = 0.8 g/c[tex]m^{3}[/tex] or 0.8 g/mL

A segment of dna/chromosome containing the instructions for building a protein which will result in a trait is called a ___
Answer: A segment of dna/chromosome containing the instructions for building a protein which will result in a trait is called a GENE.
Explanation:
CHROMOSOMES are made up of two threads called chromatids joined at a point called the centromere.
In the chemical nature of chromosomes, each is made up of a protein framework which has a long molecule of DNA (deoxyribonucleic acid) coiled round it. A segment of DNA containing the instructions for building a protein which will result in a trait is called a GENE.
The GENES in the cell of a diploid organism contain all the necessary instructions for building up the organism.These instructions are written on a molecular scale.. Most genes contain information to direct the synthesis of specific proteins. Each such protein takes part in the development of a particular character.
A protein is made up of one or more chains of amino acids known as polypeptides. The sequence of bases in a DNA molecule determines the type of amino acid and the sequence in which they are arranged in a polypeptide chain.
A gene therefore is a sequence of triplets of the four bases which specifies the structure of a protein
