A girl has her eyes shut and is standing inside a brightly lit room. What happens to her pupils when she opens her eyes? Why?
Answer:
When you open yours eyes in a brightly lighted area to a dark room (such as a cinema hall), you experience difficulty in seeing objects for a short while slowly, your vision is improved. This improvement is called dark adaptation. This change is due to (a) regeneration of the visual purple (or rhodopsin), the pigment of the rods, which was earlier broken down due to bright light, and (b) dilation of the pupil permitting more light to enter the eyes.
The pupil will constrict. Bright light will contract the muscles of the iris.
What is structure of an eye?An eye is a spherical structure responsible for vision.
An eye consists of three main layers:
Outer layer: It consists of cornea and sclera. Cornea extends into a membrane like structure called conjunctiva.Middle layer: This layer contains iris, ciliary body and choroid.Inner layer: Consists of retina where an inverted image of the object is formed. The optic nerve carries the visual information to brain.Two fluids namely aqueous humour and vitreous humour are present which maintain the shape of an eye.
The coloured part of an eye is called iris. It regulates the intensity of the light entering to the eye by controlling the diameter of a pupil (small aperture in the iris).
The lens of an eye is biconvex. It directs the light to the retina.
Therefore, eye is a crucial sensory organ.

Which best describes the relationship between chromosomes, genes, and inherited traits?
A Genes and chromosomes both carry DNA that determine inherited traits from parents to offspring.
B Genes are located within chromosomes. Genes determine the passing and expression of inherited traits from parent to offspring.
C Chromosomes are located within genes. Chromosomes determine genetic code for inherited traits from parent to offspring.
D Genes are controlled by chromosomes. Chromosomes create mutations and new genes that are passed from parent to offspring.
Genes are located within the chromosomes. Genes determine the passing and expression of the inherited traits from parents to the offspring. Thus, the correct option is B.
What are Genes?Gene is the basic unit of heredity and the molecular gene in the nucleus is a sequence of nucleotides in the form of DNA, which undergoes transcription to produce a functional RNA. The molecular genes are of two types: protein-coding genes and noncoding genes. The protein-coding gene undergoes translation to produce functional proteins from RNA.
Chromosomes are present on the DNA molecule which contain the genes. Genes determine the expression of traits in an organism and are transmitted from the parents to their offspring.
Therefore, the correct option is B.

Were does all the energy start from ALL the organisms
Answer:
The sun
Explanation:
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.
Answer:

Answer:
rounded clasts that are greater than two millimeters in diameter. The spaces between the clasts are generally filled with sand- and clay-size particles. The rock is bound together by a cement that is usually composed of calcite or quartz.
Answer:
Conglomerate forms where sediments of rounded clasts at least two millimeters in diameter accumulate. It takes a strong water current to transport and produce a rounded shape on particles this large. Wind transport is unlikely to produce a conglomerate.

In which bottles did fermentation occur? How do you know this?
Answer:
Bottle 2 and bottle 4
Explanation:
Whenever fermentation occurs the liquid experiences natural carbonation in a way. For example if you've ever seen a bottle of kombucha you'll see that it's constantly bubbly and it never stops bubbling. So the production of oxygen inflated the balloons.
In the bottle named as bottle 2 and bottle 4 is showing fermentation, as per the given scenario.
What is fermentation?Fermentation is an anaerobic chemical process that breaks down molecules like glucose. More specifically, fermentation is the foaming that happens during the creation of wine and beer, a procedure that has been around for at least 10,000 years.
In the absence of oxygen, carbohydrates are broken down by the enzymes of microorganisms during fermentation.
Because they possess distinctive sets of metabolic genes, microorganisms like bacteria and fungus are able to develop enzymes that can break down various kinds of sugar compounds.
Although fermentation can result in a variety of products, the most prevalent ones are ethanol, lactic acid, carbon dioxide, and hydrogen gas.
Commercial applications for these materials include use in food, vitamins, medications, and industrial chemicals.
Thus, in bottle 2 and bottle 4, one can see the inflated balloon which can be an evidence of the fermentation taking place.

A student is analyzing data that compare the change in the total number of wading bird nests in the Everglades to the change in rainfall. Wading birds feed primarily on fish. Fewer nests were observed in dry years than wet years.
What is a reasonable inference about the relationship between wading bird reproductive success and water depth in the Everglades?
The reasonable inference about the relationship between wading bird reproductive success and water depth in the Everglades is the prey density and the vulnerability of prey to capture.
What is wading bird?Waders, also known as shorebirds, are birds of the order Charadriiformes that forage for food crawling or burrowing in the mud and sand, typically small arthropods such as aquatic insects or crustaceans.
The sandpipers, snipes, and phalaropes family is a diverse group of waders that includes curlews, godwits, turnstones, sandpipers, woodcock, snipe, and phalaropes.
Shorebirds generally wade in shallow water, while others feed on rocky shores.
Prey availability, which includes both prey density and prey vulnerability to capture, can have a significant impact on wading bird foraging success and habitat preference.
Thus, due to availability of more prey in the wet area, the density of these birds are more in that particular area.

Why might dew form in the morning:
○The temperature fell overnight, and colder air can hold less water vapor.
Hope this helped you- have a good day bro cya)
Dew form in the morning because the temperature fell overnight, and colder air can hold less water vapor. The correct option is c.
What is dew?As the temperature drops and things get colder, dew forms. The air around an object will cool if it becomes cold enough. Warm air can store more water vapor than cold air, but not as much. As a result, the air around cooling objects is forced to condense water vapor.
At the night, the temperature is less because of not sun. In less temperature, water freezes, and the air consensus turns into drops of water.
Water tends to gather on surfaces and draw itself together as droplets, or dew, since it has high surface tension. It frequently gathers in locations that are naturally chilly.
Therefore, the correct option is c, The temperature fell overnight, and colder air can hold less water vapor.

Vertebrates are have well developed and long bones in legs and hands. Whereas, invertebrates have soft short and fragile bones and nerves in legs and hands.
What are vertebrates?Vertebrata, which means chordates with backbones, is the subphylum of animals that includes all types of animals. The majority of the Chordata, phylum, are vertebrates.
Underneath skin and muscle is where the vertebrate skeleton resides. The brain and spinal cord are enclosed by the skull and vertebral bones, while the heart and other internal organs are shielded by the ribs. The interior core of the legs is made up of long bones.
Exoskeletal material covers almost all exterior features on vertebrates, as well as a few internal ones. These structures include the body, legs, fore and hind digestive tracts, some respiratory surfaces, eyes, mouthparts, antennae, and antennae.
Invertebrates have no vertebral column and are have not developed bones or muscles inside. Insects, mollusks, cnidarians etc. belongs to this class. Their legs have no muscle tissues and long vertical bones.
