Answer:
Pigment
Explanation:
The normal leaves contain more of a green pigment suggesting more chlorophyll present in the plant. This increases the rate of photosynthesis meaning the plant can grow faster. Variegated leaves have variation of colours some are not green meaning they grow slower.
Hope it helped
Plants with normal leaves grow more than plants with variegated leaves because variegated leaves have reduced chlorophyll content, impacting photosynthesis and overall growth.
What is variegated leaves?Variegated leaves refer to leaves that display a pattern of different colors or shades, typically characterized by patches, stripes, or streaks of contrasting pigmentation. This variation in coloration is a result of genetic mutations or changes in chloroplast distribution within leaf cells.
In variegated leaves, the color variation is caused by differences in chlorophyll content, which is responsible for the green color in leaves. The areas with reduced chlorophyll may appear white, yellow, cream, or other colors depending on the pigments present. This variation can be stable throughout the plant's life or occur only in specific conditions or stages of growth.
Variegated leaves can be found in a variety of plant species, both in the wild and in cultivated plants. They are often valued for their ornamental appeal and can add visual interest and uniqueness to gardens, landscapes, and indoor spaces.

Consider the phylogenetic tree. A phylogenetic tree is shown. The root of the tree is dinosaurs and birds. The branches are crocodiles, primates, amphibians, ray-finned fish, and shark. Which two organisms are most closely related, based on the tree above? ray-finned fishes and sharks rodents and primates dinosaurs and crocodiles dinosaurs and birds
Answer:
dinosaurs and birds
Explanation:
Dinosaurs and birds are considered as the most closely related species to one another because they are evolved from a common ancestor. They show resemblance in many ways such as physical structure, both dinosaurs and birds moves on two feets etc. In phylogenetic tree, dinosaurs and birds are the roots from which other organism evolved. So that's why dinosaurs and birds are considered the most closely related species living on earth.
The organisms that are most closely related (based on the tree above described) are dinosaurs and birds.
Evolution and phylogenetic treesEvolution refers to the natural process of descendence with modification, which is mainly due to natural selection.
Evolution leads to speciation, thereby species are related and they show evolutionary relationships.A phylogenetic tree is a diagram that represents evolutionary relationships between species that share a common ancestor.In conclusion, the organisms that are most closely related (based on the tree above described) are dinosaurs and birds.

The number of chromosomes during meiosis is incredibly important.why is that?
Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes, Meiosis also produces genetic variation by way of the process of recombination.
I hope this helps you
Meiosis refers to the process by which a single cell divides twice to produce four haploid daughter cells. These are the gametes, which are sperms in males and eggs in females.
Why the number of chromosomes is important during meiosis?Meiosis is a eukaryotic cell division process. However, the genetic material distributed among the resulting daughter cells is distributed in very different ways by these two processes.
Mitosis results in the formation of two identical daughter cells, each with the same number of chromosomes as the parent cell.
Meiosis, on the other hand, produces four distinct daughter cells, each with half the number of chromosomes as the parent cell.
Because meiosis generates cells that will become gametes (or reproductive cells), this reduction in chromosome number is critical; without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes.
Thus, we can conclude that the number of chromosomes during meiosis is incredibly important because It allows gametes to have half the original number of chromosomes of the organism.

Why do droughts contribute to desertification?
Answer:
Drought and desertification are firmly related phenomenon. Continuing over months or years, drought can influence enormous zones and may have genuine ecological, social and financial effects.
While drought is a characteristic phenomenon, whose effects can be exacerbated by human exercises that are not adjusted to the neighborhood atmosphere, land debasement is the way toward transforming fruitful land into less or non-gainful land. In extraordinary cases in drylands this is called desertification.
Land debasement and desertification are complex phenomenon driven by un-adjusted human action in mix with land and climatic requirements. Improper land use, for example, monocultures, and unreasonable land the board rehearses, for example, deforestation, unsatisfactory agrarian practices and overexploitation of water assets), can cause land debasement that can be additionally disturbed by drought.

Determine whether the given procedure results in a binomial distribution (or a distribution that can be treated as binomial). If the procedure is not binomial, identify at least one requirement that is not satisfied. The YSORT method of gender selection, developed by the Genetics & IVF Institute, was designed to increase the likelihood that a baby will be a boy. When 150 couples use the YSORT method and give birth to 150 babies, the genders of the babies are recorded. Does the procedure represent a binomial distribution? A. No, because there are more than two categories for each trial. B. No, because the trials of the procedure are not independent. C. Yes, because the procedure satisfies all the criteria for a binomial distribution. D. No, because the probability of success differs from trial to trial.
Answer:
The correct answer is C)
Explanation:
The number of couples who used YSORT method (x) = 150That is, the number of couples who used YSORT method is limited or defined or definite.The probability of giving birth to a boy, for each couple is 1/2 or 0.5The gender of the baby born in each case mutually exclusive (Independent)

The nodes of Ranvier are the gaps which are present in the myelin sheath that coats the neural axon. The myelin sheath permits electrical impulse to move down the axon in a neuron. The nodes of Ranvier allow movement of ions in and out of the neuron that helps in propagation of electrical signals down the axon of the nerve cell.

D. Land bridges existed that are now underwater.
The truth about the last ice age: D. There was now a submerged overpass.
An ice age also called an ice age, is a geological period in which thick ice sheets cover vast land areas. These massive ice ages could last for millions of years and could radically change the surface topography of entire continents.
There have been several major ice ages in Earth's history. The amount of sunlight reaching Earth over thousands of years varies considerably, especially at the North Pole and its surrounding northern latitudes. When less sunlight reaches northern latitudes, temperatures drop, more water freezes into ice, and the Ice Age begins. This ice age began about 2.6 million years ago in a period known as the Pleistocene epoch and lasted until about 11,000 years ago. Like everything else, the Last Ice Age brought about a series of glacial advances and retreats. In fact, we are technically still in the Ice Age.
