Answer:
Declining biodiversity lowers an ecosystem's productivity (the amount of food energy that is converted into the biomass) and lowers the quality of the ecosystem's services (which often include maintaining the soil, purifying water that runs through it, and supplying food and shade, etc.).
Answer:
"When a species becomes extinct, they reduce the variety of animals, plants, or bird species from that ecosystem resulting in the extinction of the other species that were dependent on them. Different species are playing different roles in the ecosystem to maintain a balance of the world." Credits to outside sources that it won't let me say :(

What would happen to a deep sea fish brought rapidly to the surface? Explain your answer in light of the fact that gas pressure in the swim bladders of some deep sea fishes increase up to about 300 atmospheres. Also define an atmosphere as it relates to the oceans.
Answer:
Its gas-filled swim bladder explode.
Explanation:
The gas-filled swim bladder of deep sea fish is explodes when brought to the surface too rapidly because in the deep sea there is high pressure on the gases that is present in its tissue so when the fish is brought to the surface too rapidly, the high pressure is removed and the gases that were compressed in the tissue of the fish in deep sea are releases to expand that causes explode of gas-filled swim bladder. There is very high pressure in the atmosphere when we go deep into the sea which put pressure on the lungs of humans and gas-filled swim bladder of fishes which decrease its volume.

In a sample of double stranded dna if 27% of the nitrogenous bases are thymine what percentage of nitrogenous bases are cytosine?
Answer:
73%
Explanation:
Given: 27%
To find: Percentage of nitrogenous bases are cytosine
Solve: [tex]\frac{27}{100}[/tex] × [tex]\frac{100}{1}[/tex]
Firstly, divide 100% by thymine and cytosine
[tex]\frac{100}{2}[/tex] = 50
Now, If it is 50 / 50, but thymine has 27 then subtract 27 from 100
100 - 27 = 73
So, the percentage of nitrogenous bases are cytosine 73%

Answer:
Autosomal Recessive
Explanation:
The method of inheritance is autosomal recessive. Notice how the disease skips the parent generation. This indicates that parents have the recessive allele but do not express the trait. The individuals who are shaded in have two recessive alleles that were passed on from their parents, therefore they have the disorder.
How is information for a specific protein carried on the DNA molecule?
a. as a sequence of nucleotides
b. in the double helix shape of the condensed chromosome
c. in the ratio of adenines to thymines
d. as a pattern of phosphates and sugars
Answer:
b
Explanation:
Genetic information is carried in the linear sequence of nucleotides in DNA. Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs. ... In eucaryotes, DNA is contained in the cell nucleus.
The information for a specific protein is being carried on the DNA molecule as a sequence of nucleotides. Hence, option (a) is the correct answer.
Nucleic acids are of two types. They are namely deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA molecule carries the information for a specific protein. They are described as follows:
DNA is the genetic material of the cell DNA molecules undergo a process called transcription to code for codons on mRNA strand These codons tend to pair with tRNA molecule which holds the amino acids The amino acids will then form a chain in the sequence of DNA nucleotides to result in protein formationThus, we can conclude that the information for a specific protein is being carried on the DNA molecule as a sequence of nucleotides. Thus, option (a) is the correct answer.

Identify how information for specifying the traits of an organism is carried in the DNA.
Answer: DNA carries all of the information for your physical characteristics, which are essentially determined by proteins. So, DNA contains the instructions for making a protein. In DNA, each protein is encoded by a gene (a specific sequence of DNA nucleotides that specify how a single protein is to be made).
Explanation:
The traits or characters are present in the DNA in the form of genes. Genes are short stretches of nucleotides present in DNA and represent the encoded message that is present in the individual.
What is a gene?Genes are present in the DNA. It carries information about the traits that are expressed in an individual. Genes come from parents to offspring, so they are hereditary and pass from one generation to the next. From DNA, mRNA is formed from the gene by the process of transcription.
This mRNA is again converted to proteins or polypeptides by the process of translation. This product is the result of the message that is present in the gene. Example: melanin pigment and skin color variation. As different persons have variations in their genes, the production of this melanin protein synthesis varies, and as a result, skin color among individuals varies.
Hence, the information for specifying the traits is carried by genes present in DNA.

Fill in the blanks using the words: glucose | monosaccharide | energy | carbon | lipids | C6H12O6 | polysaccharide | carbohydrates All matter, must contain ________________________ to be considered organic. ______________________________, composed of starches and sugars are generally used in cells as a source of ___________________________. If a carbohydrate has more than one sugar, it is considered a _________________________________. The single subunit of a polysaccharide is a __________________________________. An example of a monosaccharide is __________________________ and its formula is ___________________________.
Answer:
Carbon, carbohydrates, energy, Polysaccharide, glucose, C6H12O6.
Explanation:
All organic matter must contain carbon in its composition then it can be considered as organic compound. Carbohydrate is composed of starches and sugars are generally used in cells as a source of energy. If a carbohydrate has more than one sugar, it is considered as a Polysaccharide. The single subunit of a polysaccharide is a glucose. An example of a monosaccharide is glucose and its formula is C6H12O6 . If a carbohydrate has one sugar, it is considered as a Monosaccharide whereas If a carbohydrate has two sugar, it is considered as a Disaccharide
The correct words for the given blanks are:
1. All matter, must contain carbon to be considered organic. Organic compounds are those compounds that have carbon and hydrogen bonds.
2. Carbohydrate is composed of starches and sugars are generally used as a source of energy. Starch is a stored form of energy in plants, whereas humans have glycogen as the stored form of energy.
3. If a carbohydrate has more than one sugar, it is considered a polysaccharide. Polysaccharides are starch, glycogen, and maltose.
4. The single subunit of the polysaccharide is a monosaccharide. It is the basic form of polysaccharides, which are combined by glycosidic bonds to form oligo or polysaccharides.
5. An example of a monosaccharide is glucose. Glucose is the primary substance required for the production of energy. Its formula is [tex]\rm C_6H_{12}O_6[/tex].

If your cells couldn't go through meiosis- how could this affect you?
Answer:
An organism would not be able to reproduce without meiosis.
Explanation:
Between meiosis and mitosis, meiosis is by far not as important. If you are a asexual organism, this would be NOT IMPORTANT whatsoever. If you are a sexual organism, this would LARGLY effect you. But on a world scale, this is NOT AS IMPORTANT.
This is because, without mitosis, you could not heal and would die much much younger since your cells could not be replaced. On the other hand, without meiosis, any organism that reproduces sexually would be unable to do so, which could lead to extinction in many, many species. This would not be harmful, however, to species that can also or mainly reporuduce asexually through budding, fragmenting, or sporing. So overall:
Organisms that produce sexually would go extinct.
This is the only real affect I can think of. Since meiosis does not produce any cells aside from reproductive cells. And asexual organisms produce reproductive cells through other means.

Why would the location of resources be a concern?
A) Some areas have more access to resources than others.
B) Human populations are sometimes concentrated in areas that are lacking resources.
C) Areas with fewer resources may need to buy resources from other areas.
D) All of the above
Answer:
D is the correct option
Explanation:
why???
let's see option by option
A)if an area is having a resource then the people around it or near it will access it more which can lead to end of the resource.so there should be rule to use equal resource by everyone
B) sometimes when there is a drought or phenomena in living area so people living there might face issues with the resources they had and now they are gone.so right thing is to move from that place to ankther place where there is resources
C)in areas that are near to desert or hilly areas might not have enough resources near them. so that may cause people to spent money to bring that resources near them or energy waste will be there.so in that cases they should either renovate that place for living or not to live there.

Use the images below to answer the question. 2. What makes all of the samples different from each other?
Answer:
Shape and structure.
Explanation:
The difference in shape and structure of these pictures is responsible for the difference from each other. The organisms present in these pictures are different in their size, shape and composition of their body. Some are small and some are large, some are living while the others are non-living, some are very hard whereas the others are soft and fleshy. So the organisms present in these samples are different from each other in a variety of ways i.e. size, shape and body structure.

A. polygenic inheritance
B. dominant inheritance
C. Mendelian inheritance
D. recessive inheritance
Answer:
A. Polygenic inheritance
Explanation:
When the qualities or the attributes are passed from the parent to their progeny is called inheritance. It can be passed either sexually or asexually.
The correct answer is:
Option A. Polygenic inheritance
This can be explained as:
When a trait is regulated by two or more genes is called polygenic inheritance.Dominant inheritance occurs when the qualities from the parent possessing the dominant gene pass to the progeny.According to Mendelian inheritance paired genes assorts independently and are passed from parent to their progenies.Therefore, coat colour in horses is an example of polygenic inheritance.
