Explanation:
The area of the retina on which the light rays focus is the fovea, which is a small, central pit located in the retina that is responsible for vision, and there are rod and cone cells present in the human eye too.
What is the significance of the eyes?There are several types of eyes present in the ecosystem, such as eye patterns, and the composition of the human eye is different from that of the dog and the cow, but this is the organ of vision, which allows the individual to see the world for nutrition, predation, navigation, communication, etc. Apart from that, it provides visual information about the shape, size, and color of objects and is involved in many other functions, such as the sleep-wake cycle,
Hence, the area of the retina on which the light rays focus is the fovea, which is a small, central pit located in the retina that is responsible for vision, and there are rod and cone cells present in the human eye too.

shape related to its function?
Answer:
the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein's unique three-dimensional shape. ... Folded proteins are stabilized by thousands of noncovalent bonds between amino acids.
different photosynthetic pigments from a plant pigment extract can be separated by
The different photosynthetic plant pigments can be separated by PAPER CHROMATOGRAPHY. It is a methodology used to separate different chemical compounds based on their differential solubility.
This method (paper chromatography) uses paper sheets in order to separate mixtures of soluble substances such as, for example, plant pigments.
These paper sheets represent the 'stationary phase' through which a solution is made to pass.
Subsequently, during the mobile phase, the solvent moves through the paper sheet and thus carries (separates) different compounds with it.

What role do the macromolecules starch and simple sugars play in fruit storage and ripening?
The role that is played by macromolecules such as starch and simple sugars in fruit storage and ripening is that the unripe bananas store starch in their chlorophyll.
Macromolecules refer to very large molecules. The four main classes of macromolecules include lipids, proteins, nucleic acid, and carbohydrates.
It should be noted that starch is stored in the chlorophyll content of the peel of the unripe bananas. During ripening, there'll be an increase in the breakdown of the starch that can be found in the fruit and this will ensure there's an increase in the glucose too.

drag each micrograph to the target that indicates the stage of mitosis or cytokinesis it shows.
Mitosis occurs after the interphase and involves four stages. After mitosis event occurs cytokinesis. The correct order is 1A, 2F, 3E, 4B, 5C, 6D.
------------------------------------------
Mitosis is a process by which, from a diploid somatic cell (2n), two daughter diploid cells (2n) are produced.
First occurs duplication of the cell content, and then the separation into two new cells happens.
Mitosis occurs in only one phase.
• In the prophase, it occurs chromosomes condensation and nuclear membrane breaks.
• During the metaphase, chromosomes are taken toward the center of the cell by the spindle apparatus. Once in the equatorial plane, chromosomes line up.
Each chromatid joins with a microtubule of opposites poles.
• In Anaphase, bonds between chromatids break. They separate and migrate to the opposite poles.
• In telophase, duplicated chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole.
• Finally, cytokinesis occurs. Through invagination of the cell membrane, the cells and their cytoplasmatic content get separated.

35. Your body uses insulin to?
a help reduce blood sugar.
b. help increase blood sugar.
c. allow cells to take in glucose.
d. reduce homeostasis.
Answer:
C
Explanation:
Insulin is a hormone that helps control your body's blood sugar level and metabolism -- the process that turns the food you eat into energy. Your pancreas makes insulin and releases it into your bloodstream. Insulin helps your body use sugar for the energy it needs, and then store the rest.
Glucagon interacts with the liver to increase blood sugar, while insulin reduces blood sugar by helping the cells use glucose.

what percentage of genetic information is passed on from parents to their offspring
Answer:
50% from each parent
Explanation:
The percentage of genetic information passed on from parents to their offspring is 50% from each parent, for a total of 100%.
What is the percentage of genetic information?Approximately 50% of genetic information is passed on from each biological parent to their offspring. This occurs through the combination of genetic material during fertilization, where half of the offspring's genetic material comes from the mother and the other half from the father.
However, the exact percentage of genetic information passed on can vary due to factors such as genetic mutations and recombination during meiosis.
This occurs through the process of sexual reproduction, where each parent contributes one gamete (sperm or egg) containing half of their genetic information.
When the sperm and egg combine during fertilization, they form a zygote with a complete set of genetic information (100%), half from each parent.
