Which is the best example of a suspension
Answer:
Emulsions are a type of suspension, where two immiscible liquids are mixed together. Examples of suspended solutions include salt water, sand in water, and muddy water.
Explanation:
California condors (Gymnogyps californianus) are listed on the IUCN Red List as being critically endangered. Since 2003, the California Condor Recovery Program has been reporting their demographic data. In 2012 they estimated the number of individuals living in the wild to be 235. If their intrinsic rate of natural increase is 0.089 ind/year, predict the size of the California condor population in 2022.
Answer:
≈ 572
Explanation:
Predict the size of the California condor in 2022
we can predict this value with this relation below
Nt = No*e^(rt) --- ( 1 )
where ; Nt = Future population , No = initial population, r = intrinsic rate of increase , t = time
No = 235
r = 0.089
t = 2022 - 2012 = 10
Insert values into equation 1
Nt = 235 * e^( 0.089 * 10 )
= 235 * e^0.89
≈ 572
Therefore the size of the California condor population in 2022 ≈ 572

6.) State the principle of dominance? I
Answer:
Please find the answer below
Explanation:
According to the convener, Gregor Mendel, the law of dominance states that one allele of a gene called DOMINANT ALLELE possess the ability to mask the phenotypic expression of another allele called RECESSIVE allele.
This law explains that in a heterozygous state of a gene, the dominant allele will always be expressed over the other. For example, in the trait of height, if T is tall and dominant, it will mask the allele of the other phenotype.
There is a great diversity of metabolism in microbes, with new types being discovered regularly. For example, the use of nanowires by the ANME and SRB was only discovered relatively recently (the study described in the introduction was published in 2015). Understanding microbial metabolism is essential to understanding how these organisms function within an ecosystem, including understanding symbiotic associations such as that between ANME and SRB. The terminology below describes metabolic types. Match each metabolic type with the best description.

1. Syntrophs
2. Autotrophs
3. Chemolithotrophs
4. Mixotrophs
5. Heterotrophs
6. Phototrophs
7. Chemotrophs
Answer:
a. mixotrophs
b. autotrophs
c. syntrophs
d. phototrophs
e. heterotrophs
f. chemolithotrophs
g. chemotrophs
Explanation:
Autotrophs are organisms that can synthesize their own food using carbon dioxide (CO2) and water (e.g., algae, cyanobacteria, plants, etc). Syntrophs are organisms that utilize products from other organisms (e.g., mites that consume human dead-skin). Phototrophs are organisms that synthesize their own food by using the energy provided by sunlight (e.g., green plants). Heterotrophs are organisms that cannot synthesize their own food, obtaining energy and nutrients by consuming other organisms (e.g., animals). Mixotrophs are flexible organisms that obtain their food by using a mix of different sources of energy and carbon. Protists that combine autotrophy and heterotrophy are considered mixotrophs. Chemotrophs are organisms that obtain energy by the oxidation of electron donors from the environment, by using both organic sources (chemoorganotrophs) and inorganic sources (chemolithotrophs). Examples of chemolithotrophs include sulfur/iron-oxidizing bacteria, while chemoorganotrophs include the most known bacteria and archaea.

What is the likely effect of removing the wildcat on the population of ows and rabbits.
Think all the way down to the mouse.
PLZ HELP
Answer:
Rabbits would survive because there's 1 less predator preying on them, therefore they will reproduce more rabbits and rabbits will overpopulate. And the same thing will happen with the mice, therefore the owls will have less competition over food and their population will grow.

Scientists build models based on what they know from previous research to derive testable hypotheses.Independently, both Watson and Crick and their competitor Linus Pauling constructed an incorrect triple-helix model with the nitrogenous bases arranged so they were on the exterior of the molecule and the phosphate groups on the interior. What evidence caused Watson and Crick to revise their model (CHOOSE 2)
Answer:
Hello. You didn't show the answer options, but we can consider that Watson and Crick revised the DNA model after seeing DNA images taken through Franklin's x-ray and by observing the pairing of the nitrogenous bases.
Explanation:
For a long time it was believed that the DNA molecule had 3 strands, instead of two, however this information was inaccurate and although defended by some scholars it was somewhat controversial and showed the need for further investigation. With that in mind, Watson and Crick decided that it was necessary to evaluate DNA in a three-dimensional way and therefore, they obtained x-ray images of DNA molecules, taken by Franklin. In these images, it was possible to notice that the DNA had two strands, instead of three. To prove this discovery, Watson and Crick analyzed the nitrogenous bases discovered by Chargaff and the way they were paired, coming to the conclusion that the DNA had two strands.

what type of weather is associated with a continental polar air mass
Answer: Cold and dry, originating from high latitudes, typically as air flowing out of the polar highs.
Explanation:
. To calculate the probability that an individual taken at random from a population has a particular genotype (AA, Aa, aa), biologists usually think in terms of a pool containing all the alleles from all the parents, known as the gene pool. This is particularly useful when it is impossible to keep track of ancestry (otherwise known as a pedigree).

If Earthquake X measured 1 and Earthquake Y measured 3 on the Richter scale, then
A. Earthquake Y had three times the ground motion of Earthquake X.
B. Earthquake Y had ten times the ground motion of Earthquake X.
C. Earthquake Y had 100 times the ground motion of Earthquake X.
D. None of the above
Answer: C. Earthquake Y had 100 times the ground motion of Earthquake X.
Explanation:
The Richter Scale is used to measure the intensity of earthquakes by comparing them to each other. There are 10 levels to the Richter Scale and each level is 10 times more intense than the last level.
If earthquake X measured 1 on the scale and earthquake Y measured 3, then Y was (10 * 10) times the intensity of X thereby placing Y at 100 times the intensity and ground motion of earthquake X.
types of adaptation and explain
Answer:
The three basic types of adaptations, based on how the genetic changes are expressed, are structural, physiological and behavioral adaptations. Most organisms have combinations of all these types.
Explanation:
Living things are adapted to the habitat they live in. This is because they have special features that help them to survive. The development of these special features is the result of evolution due to gene mutation. These mutations aid in the survival and reproduction and passes on from one generation to the other.
Answer:
Behavioural-Physiological-Structural
Explanation:
Behavioural - responses made by an organism that help it to survive/reproduce.
Physiological - a body process that helps an organism to survive/reproduce.
Structural - a feature of an organism's body that helps it to survive/reproduce.
