What is the longest phase in a star's life cycle?
Answer:
T-Tauri Phase
Explanation:
The mean temperature of the Tauri star isn't enough to support nuclear fusion at its core. The T-Tauri star lasts for about 100 million years, following which it enters the most extended phase of development – the Main sequence phase.
Movement of the particles across the membrane stops when the concentration gradient no longer exists, the particles will continue to diffuse due to random motion
Answer:
Once the concentration gradient no longer exists, particles will continue to diffuse due to random motion.
Explanation:
When there is a permeable membrane between two solutions with different concentrations, the concentration gradient will go from the compartment with more particles to the one with fewer particles to valance the concentrations on both sides of the membrane. Once the concentrations are equal, particles will still randomly move from one side to the other, but the number of particles that move to one side is almost the same as the number of particles that move to the other, so there is still valance and the same concentration in both sides.

When the availability of resources in an area is limited, organisms may leave a population to move to an area with more resources. What is this movement called? birth rate death rate O emigration immigration
Answer:
Emigration immigration
Explanation:
Emigration means an animal leaves its home because the habitat is no longer ideal for them, and they need to find a more suitable environment. Animals that immigrate or emigrate do not return to the land they left.
When the availability of resources in an area is limited, organisms may leave a population to move to an area with more resources, so the movement is called as Emigration. So, the correct option is C.
What is Emigration?Emigration is defined as the act of leaving one resident's country or place of residence with the intention of settling elsewhere while immigration describes the movement of people from one country to another. A migrant emigrates from his old country, and immigrates to his new country.
Emigration affects the economies of the countries which is involved in both positive and negative ways depending on the current state of the countries' economies. This has an economic impact on the countries involved, including the workforce and consumer spending.
Therefore, the correct option is C.

what is the size of image formed in plane mirror
The size of the image formed in the plane mirror is the same as the actual object standing in front of the mirror, and in the plane mirror there is no change in the image.
What is the importance of the plane mirror?A plane mirror has many uses, as they are used in optical instruments such as mirrors, which help in directing and focusing light in optical systems, and the plane mirror also helps in educational demonstrations, such as the laws of reflection and image formation in different educational institutes, etc. The most important significance is that a plane mirror generally makes an image that is the same as the object.
Hence, the size of the image formed in the plane mirror is the same as the actual object standing in front of the mirror, and in the plane mirror there is no change in the image.

What is structure of eye?Three coats enclose the optically clear aqueous humour, lens, and vitreous body in the eye.
The cornea and sclera form the outermost coat; the choroid, ciliary body, and iris form the middle coat, which contains the main blood supply to the eye and extends from the back to the front.
The eye functions as a sensory organ. It collects light from our surroundings and converts it into nerve impulses. The optic nerve sends these signals to the brain, which creates an image and thus provides sight.
Thus, as per the labeling number, Vitreous gel, Optic Nerve, Macula, Fovea, Retina, Lens, Pupil, Cornea, Iris respectively are the parts of eye.

Edith Widder: Glowing life in an underwater world
1. On her first open-ocean dive in the Santa Barbara Channel, Widder says she dove down to 880 feet and turned off her lights. Explain why she did this and how she described what she saw?
2. If you happen to be on a ship and go to use the bathroom at night without turning on the light, why does Widder explain you might think you are having a “religious experience”?
3. Why are most people who are studying bioluminescence today focused mainly on the chemistry behind it? What does the Nobel Prize have to do with this?
4. What makes bioluminescence an important factor of survival for so many animals? Provide one example Widder gives to explain this.
5. Why is Widder dissatisfied with the way we explore the ocean? What are the two main ways we learn about what lives in the ocean that she describes?
6. How does Widder tell the difference between the species she observes in the deep ocean? Give an example of a species she identifies based on this observation.
Answer:
1. She turned off the lights because she knew that she would see a phenomenon of animals making light called bioluminescence. She described that she was totally unprepared for how much there was and how spectacular it was. She saw chains of jellyfish that were pumping out a lot of light; and puffs and billows of what looked like luminous blue smoke and sparks of blue light from the thrusters.
2. The head on ships which are the toilets on ships are flushed with unfilltered seawater that often has bioluminescent plankton on it. So, if you stagger into the haed late at night and you're toilet-hugging sick, that you forget to turn on the light, you my think that you're having a religious experience.
3. They are focusing on the chemistry because these chemicals have proved so incredibly valuable for developing antibacterial agents, cancer fighting drugs, testing for the presence of life on Mars, detecting pollutants in our waters which is how it is used at ORCA. In 2008, the Nobel Prize in Chemistry was awarded for work done on a molecule called green fluorescent protein that was isolated from the bioluminescent chemistry of a jellyfish, and it has been equated to the invention of the microscope, in terms of the impact that it has had on cell biology and genetic engineering.
4. What makes it important for the survival of many animals is for the animals that are trying to avoid predators by staying in the darkness, light can still be very useful for the three basic things that animals have to do to survive: and that's find food, attract a mate and avoid being eaten.
5. The primary ways that we know about what lives in the ocean is we go out and drag nets behind ships. The other primary way is we go down with submersibles and remote-operated vehicles. Doing that there are bright lights and thrusters that disturbs the animals and makes then go away.
6. She was able to tell the difference between the species by the types of flashes they produced like the big explosions, sparks, are from a little comb jelly.

which is true regarding the process of meiosis I?
A) chromosome Number is reduced from diploid to haploid
B) sister chromatids in a cell undergoing are always identical
C) Most homologue pairs do not have any crossovers during prophase I
D) sister chromatids separate to opposite ends of the cell
Answer: The correct option is A (chromosome Number is reduced from diploid to haploid)
Explanation:
In sexual reproduction, offspring are produced by fusion of two different sex cells which usually come from two different parents. These sex cells are know as gametes.
Meiosis is a type of cell division that gives rise to gametes in which the chromosome number is halved. Thus, the gamete cell is said to contain a haploid number (n) of chromosomes.
A diploid cell has two sets of chromosomes: one from the male parent and the other from the female parent. When a diploid cell undergoes meiosis the following occurs:
--> the chromosomes replicate once and
--> the nucleus and cell duplicate ( divide equally) twice.
As a result, the diploid parent cell gives rise to four haploid gamete cells. Therefore the statement "chromosome Number is reduced from diploid to haploid ' is true concerning meiosis I.

What are two genotypes that could produce a dominant phenotype?
Answer:
A homo-zygous dominant genotype and a heterozygous genotype
Explanation:
A homo-zygous dominant genotype refers to a genotype that contains two copies of the dominant gene variant, i.e., two dominant alleles at its locus, thereby individuals carrying this genotype will show a dominant phenotype. Moreover, a heterozygous genotype is a genotype that contains both dominant and recessive alleles at its locus. In a heterozygous genotype, the dominant allele is always expressed and masks the recessive allele, thereby showing a dominant phenotype.
