What happens to the environment as a result of decreased biodiversity?
O Pollution increases.
O The earth becomes more exposed to asteroid impact.
O Species can no longer migrate to faraway islands.
O Ecosystems become less stable.
Answer:
Pollution increases
Explanation:
Pollution is a major threat to biodiversity, and one of the most difficult problems to overcome; Pollutants do not recognize international boundaries. For example, agricultural run-off, which contains a variety of fertilizers and pesticides, may seep into ground water and rivers before ending up in the ocean. Atmospheric pollutants drift with prevailing air currents and are deposited far from their original source.
explain why it is an advantage for plants to store carbohydrates as starch rather than as sugars
Answer:
More energy are packed into less space by starch molecules far more than glucose or sucrose yet they are able to release this energy easily, hence maximizing both storage and mobilization.
Explanation:
When plants have a period of dormancy to survive, they store their food as starch. They store enough of this energy so as to be able to restart with and to be able to maintain metabolism for the entire period of dormancy.
In addition, we know that starch is not water soluble, hence, lacks the ability to pull water into storage cells or cause irregularity in water balance. More energy are packed into less space by starch molecules far more than glucose or sucrose yet they are able to release this energy easily, hence maximizing both storage and mobilization.
Glucose is not directly transported by plants to storage. Rather, in a plant stem, the form of carbohydrate being transported is sucrose and this is because it is a non-reducing and does not react with oxygen during transport in the stem to specialized storage plastids.
It is advantageous for plants to store carbohydrates as starch rather than as sugars because:
sugars such as sucrose, fructose, and glucose are soluble and cannot be stored in the body of plant.as such, plants have to find a way to store their food reservesone way to store the food would be to store them in less soluble form that cannot be washed away easily and can also be converted to usable forms when needed.Hence, starch provides for that option. Cellulose could also have been a choice, but its structure makes it such that it becomes a permanent part of the plant and cannot be converted to usable food anymore.Hence, it is advantageous to store carbohydrates as starch by plant rather than sugars because starch cannot be washed away easily and can also be converted to usable foods when needed.

Write a scientific explanation to explain how natural selection and adaptation increase or decreases the chances of survival for the mice if they entered one another’s environment.
Answer:
Natural selection is a factor of biological evolution, by means of which individuals who possess a certain characteristic tend to prevail over those who lack such characteristic. Thus, by reproducing, individuals with favorable characteristics end up imposing their own set of characteristics, taking control of the environment in which they develop and relegating other individuals or condemning them to their extinction or displacement.
Thus, in the case, if some mice entered the environment of others, most likely they would not be able to adapt to the conditions to which the original group of that environment had previously adapted. In this way, natural selection itself would make the new mice end up disappearing from it, in favor of the mice that already lived there and that, therefore, had adapted their characteristics to those of the environment.
why do we commonly see isotherms on local weather broadcasts?
Explanation:
Isotherms are lines of constant or equal temperature. They are often used on weather maps by meteorologists to give a large scale view of temperatures across the U.S. If you have ever looked at a weather map in a newspaper, the isotherms are used to divide the color-filled temperatures.

How much DNA is in Calix's cells compared to the control? (Meowsis STEM gizmo)
DNA) is a molecule composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid (RNA) are nucleic acids. Alongside proteins, lipids and complex carbohydrates (polysaccharides), nucleic acids are one of the four major types of macromolecules that are essential for all known forms of life.
The structure of the DNA double helix. The atoms in the structure are colour-coded by element and the detailed structures of two base pairs are shown in the bottom right.
The structure of part of a DNA double helix
The two DNA strands are known as polynucleotides as they are composed of simpler monomeric units called nucleotides.[2][3] Each nucleotide is composed of one of four nitrogen-containing nucleobases (cytosine [C], guanine [G], adenine [A] or thymine [T]), a sugar called deoxyribose, and a phosphate group. The nucleotides are joined to one another in a chain by covalent bonds (known as the phospho-diester linkage) between the sugar of one nucleotide and the phosphate of the next, resulting in an alternating sugar-phosphate backbone. The nitrogenous bases of the two separate polynucleotide strands are bound together, according to base pairing rules (A with T and C with G), with hydrogen bonds to make double-stranded DNA. The complementary nitrogenous bases are divided into two groups, pyrimidines and purines. In DNA, the pyrimidines are thymine and cytosine; the purines are adenine and guanine.
Both strands of double-stranded DNA store the same biological information. This information is replicated as and when the two strands separate. A large part of DNA (more than 98% for humans) is non-coding, meaning that these sections do not serve as patterns for protein sequences. The two strands of DNA run in opposite directions to each other and are thus antiparallel. Attached to each sugar is one of four types of nucleobases (informally, bases). It is the sequence of these four nucleobases along the backbone that encodes genetic information. RNA strands are created using DNA strands as a template in a process called transcription, where DNA bases are exchanged for their corresponding bases except in the case of thymine (T), for which RNA substitutes uracil (U).[4] Under the genetic code, these RNA strands specify the sequence of amino acids within proteins in a process called translation.
Within eukaryotic cells, DNA is organized into long structures called chromosomes. Before typical cell division, these chromosomes are duplicated in the process of DNA replication, providing a complete set of chromosomes for each daughter cell. Eukaryotic organisms (animals, plants, fungi and protists) store most of their DNA inside the cell nucleus as nuclear DNA, and some in the mitochondria as mitochondrial DNA or in chloroplasts as chloroplast DNA.[5] In contrast, prokaryotes (bacteria and archaea) store their DNA only in the cytoplasm, in circular chromosomes. Within eukaryotic chromosomes, chromatin proteins, such as histones, compact and organize DNA. These compacting structures guide the interactions between DNA and other proteins, helping control which parts of the DNA are transcribed.

Answer:
Selective breeding.
Explanation:
Sorry thats the only one i can think of. BTW have u watched lucky star.

A plant with a yellow pod can have two green pod parents if the gene for yellow color pod is recessive in the both parents.
Genes often occur in pairs called alleles. An allele may consists of a pair of genes which may or may not be the same. This is how an offspring could have a phenotype different form that of its parents.
The gene that is expressed is said to be dominant while the gene that is not expressed is said to be recessive. A plant with a yellow pod can have two green pod parents if the gene for yellow color pod is recessive in the both parents.

A red blood cell has a salt concentration of 0.9%. What will happen if it is placed into
a 0.8% salt solution? The red blood cell will
burst
remain the same
shrink then grow
shrink
Answer:
Shrink
Explanation:
The blood cell would shrink because of osmosis. The molecules move with the concentration gradient so water molecules will move outside of the cell where there is less water than inside of the cell.
Blood cells are the main constituents of the circulatory system and carry the most vital function of oxygen transportation. Blood cells have a specific concentration and osmotic pressure to remain vital.
The correct answer is:
Option D. Shrink.
This can be explained as:
Cells have a tendency to shrink in hypertonic solutions while swells in hypotonic solutions.0.8% of the salt solution will act as a hypertonic solution and the RBC placed in it will shrink.When cells are placed in hypertonic solution it loses their water content to the outside surface and hence shrink.Therefore when the red blood cells are placed in 0.8% salt solution they will shrink.

In the laboratory, a genetics student crossed flies with normal, long wings to flies with mutant, dumpy wings, which she believed was a recessive trait. In the F1, all flies had long wings. In the F2, the following results were obtained: 672 long-winged flies 218 dumpy-winged flies The student tested the hypothesis that the dumpy wing is inherited as a recessive trait by performing chi-square analysis of the F2 data.
Determine:
a. Chi-Square Value.
b. Degrees of freedom.
c. Reject or fail to reject the hypothesis.
Answer:
a. Chi-Square Value = 0.12
b. Degrees of freedom = 1
c. Reject or fail to reject the hypothesis = fail to reject the hypothesis
Explanation:
Available data:
Cross: long wings to flies with mutant, dumpy wingsF1) 100% long-winged fliesF2) 672 long-winged flies 218 dumpy-winged flies Hypothesis: the dumpy wing is inherited as a recessive traitLet us name the allele for Long L and the allele for dumpy l
The number of observed individuals:
Total number: 890 flies (672 + 218) Long-winged = 672 Dump-winged = 218In the F2 generation, if l was a recessive allele and L a dominant allele, exhibiting complete dominance, we would expect a 3:1 phenotypic ratio.
Cross: Ll x Ll
Gametes) L l L l
Punnett square) L l
L LL Ll
l lL ll
F2) 3/4 LL + Ll long-winged individuals
1/4 ll dump-winged individuals
From this ratio and the total number of individuals in the F2 generation, we can get the expected number of individuals:
4 possible genotypes ------- 890 individuals
3 LL + Ll genotype ------------X = 667.5 long-winged individuals
1 ll genotype ---------------------X = 222.5 dump-winged individuals
Chi square = ∑ (O-E)²/E
LL + Ll = (O-E)² /E
LL+ Ll = (672 - 667.5) ² / 667.5
LL + Ll = 0.03
ll= (O-E)²/E
ll= (218 - 222.5)² / 222.5
ll= 0.09
Chi square= ∑ ((O-E)²/E) = 0.03 + 0.09 = 0.12 Freedom Degrees = genotypes - alleles = 3 - 2 = 1 Significance level = 0.05 Table value/Critical value = 3.84
0.12 < 3.84 meaning that there is enough evidence to reject the null hypothesis.
Fail to reject the hypothesis. The genotypes in the population might be in equilibrium H-W. L is the dominant allele, and l is the recessive allele. The dumpy wing is inherited as a recessive trait.
