If you soak seeds in water to soften them, and then cut them in half and stain them with iodine, most of the inside of the seed will change color, turning a purplish-black. What substance is the iodine reacting with to cause this color change?
Answer:
Starch
Explanation:
Starch consists of amylopectin and amylose, and is found in plants. In the presence of iodine, amylose starch turns a dark purple or blue color, due to the absorption of different wavelengths of light than before.

A. Identify the letter of the image that does NOT represent aseual reproduction. B. Explain how you can tell that this image is not aseual reproduction.
Answer:
D
Explanation:
Aseual reproduction is a type of reproduction in which new organisms are reproduce from single parent without production of gametes. But in D their is fusion of gametes (egg and sperm) therefore it explains to us that it is not an aseual reproduction.
In these analyses, why are segments of chromosomes (haplotypes) rather than individual strs used to identify genetic relationships?
The type of analysis is not specified here, but haplotypes are used to identify phylogenetic and phylogeographic relationships.
Whta are haplotypes?The haplotypes are linear sequences of nucleotides whose order can be used to determine evolutionary relationships.
The haplotypes are very useful in phylogeny and phylogeography to study the features of species.
The term haplotype is broader than genetic sequence because a haplotype is more informative (a priori).

The segments of chromosomes (Haplotypes) are used to identify genetic relationship because it carries almost all the information, properties, and characteristics of the individual genome.
What do you mean by Genetic relationship?Genetic relationships may be defined as the similarities in the sequence of the genome between the organisms of two or more species.
Haplotypes are used to identify the evolutionary relationships between the species. It also analyzes the various features that a species possess in its genome.

What is the genotype of the parents if allele b is dominant over allele b?.
The dominant characteristic will be phenotypically manifested in offspring whose genotype could be BB or Bb.
What is genotype?An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual possesses in a certain gene or genetic region are also referred to as the genotype.
The amount of copies of the each chromosome contained in that species, commonly known as ploidy, determines how many alleles a person can have for a certain gene. In diploid organisms like humans, there are two complete sets of chromosomes, which means that each person possesses two alleles for each gene. The dominant characteristic will be phenotypically manifested in offspring whose genotype could be BB or Bb.
Therefore, the dominant characteristic will be phenotypically manifested in offspring whose genotype could be BB or Bb.

What is always at the start of natural selection?
A: reproduction
B: mutation
C: passing on genes
Answer:
passing on genesExplanation:
Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

For this assignment, you will develop a model to describe the cycling of matter and the flow of energy
among living and nonliving parts of an ecosystem. This project includes both an individual and a group
part. On your own, you will research an organism that is assigned to you. In your group, you will combine
your organism with the organisms researched by other students to create a food web. Together, you will
write two short paragraphs explaining how energy and matter move through the food web.
Answer:
All I can tell you is when energy is moves through the food web it gets divided by 10
plant energy =1 0,000 (example)
that plant gets eaten by a small animal
small animal's energy gained from the plant = 1,000
a large animal then eats the smaller one
large animal's energy gained from the small animal = 100

Explanation:
how is an increased in carbonin the atmosphere likley to affect coastal areas such as those in north carolina
Answer:
D
Explanation:
The amount of Carbon dioxide (CO₂) that is trapped in the atmosphere is released by the burning of the fossil fuels and from the industrial pollution. In addition to this, some amount of it also released by the animals and human beings. This stored CO₂ in the atmosphere is then transported to the oceans with the help of rainfall. When this CO₂ reacts with water it forms weaker acid, which is commonly known as the Carbonic acid. Due to this, the pH level of ocean water decreases. As a result of this, it affects the ocean water chemistry and the marine life. Due to this ocean acidification, the marine species namely the corals and various types of planktons are not able to form the hard parts like the shell and skeletal parts. This carbonate water dissolves the existing shells and erodes the particles away. The increase in the carbon content in the atmosphere will also lead to precipitation that will wash away the rock particles and other sediments, that are present in the coastal areas. In addition to this, the plants also will be affected due to this carbon containing water.

At room temperature, dry ice (carbon dioxide, CO2) changes directly from solid to gas. What happens as the solid dry ice turns into carbon dioxide gas?
A.CO2 molecules lose mass to become gas.
B.CO2 molecules release heat energy to the air.
C.CO2 molecules absorb heat energy from the air.
D.CO2 molecules react with oxygen and become gas.
Answer:
A
Explanation:
Carbon dioxide is a gas at room temperature.
When the solid dry ice turns into carbon dioxide gas, the carbon dioxide molecules release heat energy into the air. Thus, the correct option for this question is B.
What happens when the solid dry ice turns into carbon dioxide gas?When the solid dry ice turns into carbon dioxide gas, the process of sublimation occurs. This process of sublimation significantly converts the dry ice into a gas in the form of water vapor.
It may be revealed that dry ice is known for carbon dioxide in its solid state of matter. The unique property of this dry ice is that it ultimately turns from a solid to gas at room temperature. This is because it provokes water vapor in the air to be condensed into droplets of water thus constructing a fog appearance.
Therefore, the molecules of carbon dioxide release heat energy into the air. Thus, the correct option for this question is B.
