how are karyotypes made?

Answers

Answer 1

Answer: A karyotype is simply a picture of a person's chromosomes. In order to get this picture, the chromosomes are isolated, stained, and examined under the microscope. Most often, this is done using the chromosomes in the white blood cells. A picture of the chromosomes is taken through the microscope.

Explanation:

Answer 2
Answer:

Karyotypes are prepared from mitotic cells that have been arrested in the metaphase or prometaphase portion of the cell cycle when chromosomes assume their most condensed conformations. A variety of tissue types can be used as a source of these cells.

Answers

This type of plant tissue you’re talking about is Vascular

Vascular tissue contains open vessels that transport water, ions, minerals, and nutrients throughout a plant.

Vascular plant tissues in higher plants can be divided into phloem and xylem.

These tissues (vascular) are fundamental to transport water and solutes to all tissues of a plant.

Conversely, meristematic tissue is a type of tissue composed of undifferentiated cells.

In conclusion, vascular tissue contains open vessels that transport water, ions, minerals, and nutrients throughout a plant.

1. A student is completing a Punnett square for a trait (X/x) that is autosomal and inherited by the dominant allele. The father does not have it (xx), but the mother does (Xx). If they had two children, a son and a daughter, what would the completed Punnett square look like (i.e., would the son have the trait, would the daughter have the trait)?

A. Both children would not inherit the trait.

B.Both children would inherit the trait.

C. Each child has a 50% chance of inheriting the trait.

D. One child would inherit the trait and one child would not.

Answers

Answer:

C

Explanation:

autsomsal means that it is not x-linked/ realted to gametes. Dominate means that it needs only one X to get the trait

Using the punnet square

             X       x

      x     Xx   xx

      x     Xx   xx

there is 2 X which means there is a 50% change that their child will get the trait

In the punnett square analysis, each child has a 50% chance of inheriting the trait.

The mother Xx has the trait and the father xx doesn't.

Using the punnet square

Xx                 xx

Xx   Xx  xx  xx

There are just two traits which are Xx and xx which are in equal frequency

and proportion.

This therefore means that the children have a 50% chance of getting the trait.

Justify how this compound was created from a recycling of carbon in the carbon cycle. Use complete sentences to explain your answer.

Answers

Answer:

part 1: Carbon dioxide

part2: combustion, respiration

part3:

- carbon in the atmosphere is removed by green plants and phytoplanktons in water bodies through the process of photosynthesis.

-The CO2 is then incorporated into carbohydrates such as sugar or starch and eventually to lipids and proteins .

-The plants are later on consumed by the animals and the organic matter in the plants are digested b,absorbed and make up the animal tissues.

-The formation of fossil fuels(fossilization) and limestone also removes CO2 from the atm.

-CO2 in the atm also dissolve in water to form acid rain thus removing CO2 from the atm.

- CO2 is added into the atm by respiration. During respiration plants and animals oxidize carbon compounds in their cells breaking them to CO2 and water which are later excreted into the atmosphere.

- When plants and animals die their remains are broken down by saprophytic organisms converting the carbon compounds to CO2 which is released into the atm.

- When eruption occurs gases are released into the atm amongst which is CO2 thus increasing its conc in the atm.

Explanation:

From what I could understand the first part of part three talks abt the removal of carbon dioxide from the atm while the second part talks abt its addition. I hope I got it right.

In 1919, the International Astronomical Union (IAU) was established. Its goal is to encourage and protect astronomy in all of its forms, including research, interaction, education, and development, through international cooperation.

The International Astronomical Union (IAU) is the oldest intergovernmental organization of professional astronomers, having been in existence for over a century. It has over 13000 members and 82 national members, among them India.

The IAU designates a constellation by its boundary rather than its pattern, and the same constellation can have multiple representations. Asterisms should be distinguished from constellations.
