The group of foods that would test positive for starch in the presence of iodine would be noodles, bread, or crackers.
Noodles, bread, or crackers consist largely of starch. Starch has the capacity to turn the brown color of iodine to blue-black because the iodine molecules insert themselves in the structure of the amylose content of the starch.
Foods like steaks, hard-boiled eggs, and chicken are essentially made of proteins and will, therefore, fail the iodine test for starch.

Which ecosystem is more stable - a potato field or a forest?
Answer:
A forest ecosystem is more stable than a potato field.
Explanation:
The forest ecosystem is a natural one and all the elements are balanced, they are managed by the nature itself.
The forest ecosystem is a natural one, and all the components are in harmony since nature herself manages the ecosystem.
Thus, A forest ecosystem, or simply a forest, is a community of plants, animals, microorganisms, and other species that interact with the chemical and physical elements of their environment.
The species in a forest ecosystem are depending on one another in order to survive, and they can be roughly categorized as producers, consumers, and decomposers based on their ecological roles.
The boreal forest that surrounds the Earth in northern latitudes is an example of a vast forest ecosystem. A forest ecosystem can also be as small as a microsite on a tree limb where mosses, insects, and microscopic species coexist.
Thus, The forest ecosystem is a natural one, and all the components are in harmony since nature herself manages the ecosystem.

Which path shows how gravity causes water to move?(APEX)
Answer:
Stream , Tributary, River, and Lake
Explanation:
Stream tributary River and Lake is the path for gravity causes water to move.
What is Path for water?Evaporation, condensation, and precipitation are typically taught as three separate but interconnected stages of the water cycle. Although this is a useful model, the actual situation is far more nuanced.
Water moves through ecosystems on Earth in a variety of ways that are incredibly complicated and still not fully understood.
For better weather, climate, water resource, and ecosystem health forecasting, NOAA is working to increase understanding of the water cycle at all sizes, from the global to the local.
Evaporation, condensation, and precipitation are frequently taught as three basic, circular processes that make up the water cycle. This is a good paradigm, but in practice things are much more nuanced.
Therefore, Stream tributary River and Lake is the path for gravity causes water to move.

Which represents the cross between parent plants if one is heterzygous and has yellow-colored pods and the other is homzygous and has green-colored pods?
Yy ´ yy
YY ´ yy
Yy ´ Yy
yy ´ yy
Answer:
Its the first one
Yy is yellow (dominant) and heterozygous
yy is green (recessive)
with Yy and yy, you could only get 50% Yy(yellow) and 50% yy(green). There is no way to make only yy or YY, and in order to make 100% Yy you would need one yy and one Yy
The cross between parent plants if one is heterozygous and has yellow-colored pods and the other is homzygous and has green-colored pods - Yy yy
Heterozygous genotype:The presence of two different alleles at a particular gene locus.A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles.Y for yellow and y for green then the heterozygous parent would be - Yy with yellow phenotypePurebred genotype:
consists of gene pairs with genes that are the same allele typealso called the hozygousY for yellow and y for green then the hemzygous parent would be - yy with green phenotypeThus, the cross would be - Yy yy

Where did Margaret Mead live in the 1930s to conduct her study of cultural variation?
Answer:
Margaret Mead lived in New Guinea in the 1930s to conduct her study of cultural variation.
Explanation:
Margaret Mead lived in New Guinea in the 1930s to conduct her study of cultural variation.
What is cultural variation?Cultural variation makes reference to the rich range of cultural practices found in diverse cultures all over the world.
Gender roles, economic systems, and social structure, among a variety of other humanely as possible organized behaviors, all change from one culture to the next.
Margaret Mead conducted actual first-hand observational data of the shared, behavior patterns of several small societies in New Guinea to find out.
Mead chose to live among the people of New Guinea and take part in their activities in order to gain a comprehensive understanding of cultural variation.
Mead was best known as an anthropologist for her research on the nonliterate peoples of Oceania, particularly in terms of psychology and culture.
Thus, in 1930s Margaret Mead lived in new Guinea.

Whales are marine mammals that share a common ancestor with group of land mammals that includes hippos. Which observation provides evidence of the shared ancestry of whales and hippos? *
Answer:
Genes and amino acid sequences.
Explanation:
The ancestor of whales and hippos are the same because of the same gene and amino acid sequence. The genes and amino acid sequences of living whales were the evidence that shows ancestry of whales and hippos. This evidence indicates that million of years ago both whales and hippos were split from a same ancestor due to evolution.
