Francine is studying the karyotype of a human subject in a medical study. she observes that the karyotype shows three copies of chromosome 21. all of the other chromosomes have two copies. which conclusion about the subject is supported by francine's observations?
3 copies of chromosome in karyotype shows that person has genetic disorder called down syndrome.
What do you mean by karyotype?A karyotype test examines the structure, shape, and number of chromosomes in your body. The sections of our cells that hold your genes are called chromosomes.
Instead of having one copy of chromosome 21, an egg or sperm cell may preserve both copies. If this egg or sperm is fertilized, the baby will be born with three copies of chromosome 21. This is referred to as trisomy 21. Trisomy 21 is present in around 95% of people with Down syndrome. Instead of the usual two copies of chromosome 21, each cell in the body has three copies of chromosome 21 in this kind of Down syndrome.

In the Japanese four o’clock flower, red flower (RR) color is incompletely dominant over white flower (rr) color; the heterozygous plants have pink flowers (Rr). What kinds of offspring can be produced if a red-flowered plant is crossed with a pink flowered plant?
What is the genotype ratio of this cross?
What is the phenotype ratio of this cross?
If a red-flowered plant is crossed with a pink flower plants, the genotype ratio would be 1:1 for RR and Rr, and 1:1 for red and pink flower phenotypes.
Monohybrid crossingRed trait has the genotype RR.
Pink trait has the genotype Rr:
Crossing both:
RR x Rr
RR Rr RR Rr
Thus, only RR (red flower) plants and Rr (pink flower) plants are produced.
Genotype ratio = 1RR : 1Rr

Three cells are placed in three solutions of different concentrations. Determine the concentration of the solutions based on the predominant
movement of water molecules through the cells.
isotonic
hypertonic
hypotonic
Solution 2
Solution 1
Solution 3
The three types of solutions and concentrations can be classified as:
Solution 1: HypertonicSolution 2: HypotonicSolution 3: IsotonicWhat is the concentration of a solution?The concentration of a solution must be expressed in quantitative units. So-called concentration units are used, which are quantitative measures of the affinity of solute that dissolves. The relative amount of a substance is known as the concentration and is expressed in different units.
In this case we can classify these solutions as :
Hypertonic solution: has higher osmotic pressure and solute concentration.Hypotonic solution: has lower osmotic pressure and solute concentration. Isotonic solution: the solute concentration and osmotic pressure are equal, thus reaching equilibrium.See more about solution at brainly.com/question/7932885

What are Vascular tissues?Vascular tissues in plants are specialised tissues which transport nutrients and water through the plant. They are made up of two distinct kinds of tissues: xylem and phloem.
Xylem is in charge of carrying water and minerals that are dissolved from the plant's roots to its leaves. It is made up of many cell types, such as tracheids, vessel components, and fibres. Tracheids and vessel elements are long, hollow structures that create lengthy tubes when stacked end to end.
Sugars and other organic compounds are transported from the leaves to the remainder of the plant by phloem. There are two sorts of cells in it: sieve tube elements and cell companions. Sieve tube components are long, narrow cells that run end to end.
Therefore, the vascular tissues identify as:
a. phloem
b. xylem

what will happen if the banyan tree grows in desert what will help it to survive
Answer:
Banyans are a fig. Australia has many native fig species, some of which grow in isolated pockets in arid areas of Australia. These include Ficus macrophylla, Ficus tinctoria, Ficus rubiginosa. I have seen Ficus brachypoda, Desert Fig growing on rock in Central Australia, but right next to small bodies of water such as permanent waterholes and deep wells. If they were able to colonise dune country and gibber desert they probably would have by now and they would be far better adapted than banyans.
I find it interesting that you have suggested banyans specifically when there is a host of other Australian native plants which thrive in arid country and create a self-sustaining ecosystem which supports food plants and a great diversity of animals.
