Water leaves the cryosphere and joins the rest of the hydrosphere when it

Answers

Answer: receives the thermal energy

Explanation:

The cryosphere can be defined as the land which is covered with the surface of ice in the solid form in the form of sea ice, river ice, snow, ice glaciers, ice sheets, frozen water, and others. When the ice on the land receives the thermal energy from the sun or any other source like radiation then it melts into water and it becomes the part of the water body in the form of the hydrosphere.

At Weeks Bay there was a population of 200 alligators. In May of 2006 a new species of catfish was released into the Mississippi. These catfish reproduce very fast and soon become a rich food source for the alligator population. This provides the alligators with the energy needed for more successful reproduction. The following summer of 2007, 100 babies were born and a total of 40 gators died that year. However, the next year in early 2008 there was a terrible drought, causing 100 alligators to die.

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

Answers

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 ___

Answers

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

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

Answers

Comparing the genomes of each species to see which are most similar

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.

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

Answers

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.

Janet and William walked into the library, backpacks slung over their shoulders and their eyes glued to their phones. "When is our paper due?" Janet asked.William sighed. "Day after tomorrow. We better start." They both groaned. Each day for the past two weeks they had come to the library to work on the English paper. Each day for the past two weeks they had played games on their phones, sent very important text messages about the latest gossip, and stared at the walls. After two weeks, neither one had even pulled up the prompt for the paper.William plopped down into a chair at a table near the window. Janet tossed her backpack onto an empty chair and sat down across from him. "Let's get this over with," she said, pulling her English binder out of the bag. Across the table, William was also pulling his binder out."Wilde Paper,"he read. Then he paused. "OH! I never noticed the 'e' on the end of Wilde. That makes a lot more sense. This will be about Oscar WIlde." Janet gave him an incredulous look that seemed to say, 'DUH!'"What did you expect? We've been talking about Oscar Wilde for the past month now." It was true, too. They had spent the last month in English class reading The Picture of Dorian Gray, one of WIlde's most famous books. She began reading the assignment instructions."Go to the Hawkins Library on 22nd Street."William rolled his eyes. "Check.""Check out The Importance of Being Earnest by Oscar Wilde." Janet stopped reading and looked at William. We may have killed ourselves by procrastinating so long. We have to read a whole book for this assignment."William grimaced. "Maybe we won't." He continued reading the assignment sheet. "At the end of Act I, you will find your instructions."Janet and William both stopped. "Whaa???" Janet was stunned. The title of the assignment said Wilde Paper, but the instructions had no information on writing a paper.They sat there for nearly five full minutes staring at the assignment paper- as if looking harder at it would cause more normal instructions to appear.Finally, William stood up. "I guess we go get the book. I hope it isn't as long Dorian was." William acted like he had hated The Picture of Dorian Gray, but in reality he had liked it. It was about a man who had his portrait painted and somehow his soul had entered the painting. So anything that happened to him, actually happened to the painting instead. He didn't age, but his painting did, etc. William found it a fascinating story and had truly enjoyed reading it. He enjoyed reading it so much, that Mrs. Hicks will give anyone who reads it and sends her a summary extra credit. In fact, if you can prove you read the entire book, Mrs. Hicks will put those points in place of an entire assignment or test.Janet was already at the computer searching for the book in the system by the time William stopped thinking about Mrs. Hicks and her extra credit opportunity and started paying attention to reality again.."Looks like the book is in the back section." Janet pointed to the section of the library the book was in. It was in an alcove back behind the Young Adult Fiction section. The pair headed back to the section and started looking for the book."I hope the library has several copies and that they aren't all checked out already." Janet looked up at him, horrified. That thought hadn't occurred to her. She got so tense that she breathed an audible sigh of relief when she found it, stuffed in the middle of the 'Y' section rather than the 'W's'. "Okay," William said, "end of Act I." He started flipping the book to find the end of the first act.Janet rolled her eyes again. "We are supposed to READ the first act, Will." He didn't listen and continued flipping. "Here it is." In pencil, below the words 'End of Act I' was a note."The key to the garden is Jack's origin."Janet looked at William incredulously. Think that will make sense if we read Act I?" William shrugged and flipped the book back to the beginning.After they read Act I, Janet looked up from the book. "I think it means the garden of the library. Look! That door has a lock on it." William pulled up the lock. "Eight characters. Looks like we need seven letters and symbol of some sort. Jack's origin.
