Explain why a leaf kept in the light for 24 hours will turn an iodine solution blue-black, whereas a leaf kept in light for 24 hours and then in the dark for 24 hours will have no effect on an iodine solution
Answer:
The leaf kept in the light will turn blue-black because of the presence of starch after photosynthesizing. The leaf in the dark could not photosynthesize, which would not create starch so the iodine solution will have no effect.
Explanation:
Iodine stains a blue black in the presence of starch
how does hydrogen bond DNA strands together?
Answer:hydraulics. In each linear strand there are covalent bonds and strong bonding between bases, sugars and phosphate groups (both within each component and between components). Hydrogen bonds occur in a complimentary combination between the 2 strands and include a base with one strand, and the base with the other.

using Punnett Squares, determine the percentage of offspring which would be heterozygous from the following cross: BB x bb
A. 25%
B. 50%
C. 100%
Lets take that the father has black hair and the mother has brown hair so -->
Male × Female
Genotypes: BB × bb
Phenotypes: Black brown
Gametes: B _100%_ b_100%_
After reviewing the photo
we have
Genotypes
B: 50% (1/2)
b: 50% (1/2)
Phenotypes
Black: 50% (1/2)
brown: 50% (1/2)
Using Punnett Squares, the percentage of offspring would be heterozygous from the following cross: BB x bb is 25%. Therefore, option (A) is correct.
What are the features of punnett square method?The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach in 1905.
The Punnett square is a table in which all of the possible outcomes for a genetic cross between two individuals with known genotypes are given. In its simplest form, the Punnett square consists of a square divided into four quadrants.
A Punnett Square is a helpful tool that helps to predict the variations and probabilities that can come from cross breeding. This includes predicting crossing plants, animals, even humans with each other.

of water used by a tree in 24 hours.
Answer:
When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others. These individuals will be more likely to survive and pass on their traits to their offspring. Over many generations, these favorable adaptations build up in a population. This may lead to speciation, which is the development of a new species.When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others.

What is photosynthesis
Answer:
The process of a plant converting sunlight, carbon dioxide and water into food
Explanation:
Hey there!
Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunlight, so we eat plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae, and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the green pigment found in the chloroplasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.

Answer:
The correct answer is -
1. Blending - C
2. Straining - D
3. Detergents - B
4. Meat tenderizer (protein enzymes) - E
5. Alcohol - A
Explanation:
To extract protein from various parts of the organisms there is a scientific process that helps in successfully extract it. Organisms such as plants have a rigid cell wall that is required to be broken in order to follow the scientific process of extracting DNA and protein.
Blending use to break the cell wall of the plants such as pea cells. After breaking the cell wall one needs to dissolve the cell membrane made up of lipids with the help of soap or detergents. After the dissolving cell membrane, there is a chance to DNA gets damaged by various chemicals, therefore, alcohol is used to allow DNA to form clumps or precipitate.
Straining is used to separate the cell organelle, dissolved cell membrane from DNA and protein. Papain is a meat tenderizer and a protein enzyme that cuts or breaks the protein.

At least two parallel channels of communication flow through each lateral geniculate nucleus. One runs through the ______________ layers and a second runs through the _____________ layers.
At least two parallel channels of communication flow through each lateral geniculate nucleus. One runs through the parvocellular layers and a second runs through the magnocellular layers.
What are parvocellular and magnocellular layers?Parvocellular cells, also called P-cells, are neurons located within the parvocellular layers of the lateral geniculate nucleus (LGN) of the thalamus.
Moreover, magnocellular cells make up the magnocellular layers of the lateral geniculate nucleus. They are relatively large cells that display specialization in detecting aspects of movement, such as the location, speed, and direction of a moving object.
Therefore, magnocellular (M) and parvocellular (P) neuronal pathways that originate in the retina and project to separate M- and P-dedicated layers of the lateral geniculate nucleus (LGN) situated in the thalamus.

Three species of finches are in competition for the limited resources of an ecosystem. One species
prefers fruit to seeds. The second species prefers seeds to fruit. The third species will eat fruit or
seeds with equal preference. If the third species is removed from the area, how will the ecosystem
change?
a. Resources will be more abundant.
b. The climate of the ecosystem will change.
c. Fruit and seed resources will become less abundant.
d. Water will become more readily available.
Answer:
the answer is option a
Explanation:
The finches evolved to have different beak shapes to be able to eat the food available on the different islands.
If one species is removed then the resources will be more abundant for the other two species.
What will happen if 3rd species is removed?If the third species is removed from the area then seeds and fruits will be more available for the one and second species.
Because the third species is eating both seeds and fruits in equal preference if they are removed then these resources will be available in more abundant for the other two species.
Thus, we can conclude that the correct option is (a), Resources will be more abundant.

Answer:
A
Explanation:
Like Christopher Columbus

The type of species that is most likely to lead to the extinction of another species is known as Invasive species. Thus, the correct option for this question is A.
What is Species?Species may be defined as a cluster of organisms that can reproduce with one another in nature and produce fertile offspring.
Invasive species are those that are not native to a particular habitat. They just arrive there in search of resources that support them in order to survive and reproduce naturally.
These arrived species utilize the resources like food, space, etc. of the native species and make them oppressed to eliminate from this habitat.
Therefore, invasive species is the type of species that is most likely to lead to the extinction of another species. Thus, the correct option for this question is A.
