Karyotypes can be studied to determine an organism’s chromosomal makeup and to detect genetic defects. Turner syndrome occurs when a female has an incomplete set of sex chromosomes. Symptoms of Turner syndrome include swollen hands and feet, short stature, and infertility. Which type of chromosomal mutation is responsible for causing Turner syndrome?

Answers

Answer 1

Answer:

The answer is deletion of X chromosome in females.

Turner syndrome is caused by completely or partly missing of X chromosome in females. it is known that females have two X chromosomes with karyotype 46,XX. Females with turner syndrome have karyotype 45,XX. This syndrome is characterized by infertility, short statue, swollen hands and feet, as well as heart defects, diabetes, webbed neck (extra skin on the neck), skeletal abnormalities.

Answers

During a controlled experiment, a scientist will isolate and test (D) a single variable. A conclusion, nor a mass of information can be isolated or tested. A control group is the group that would receive a placebo, so testing that would be futile.

This is a plastid with chlorophyll in plants that photosynthesize.

Answers

Answer:

Chloroplast

Explanation:

Chloroplasts are organelles, small organs of plant cells, and other organisms capable of photosynthesis, such as algae.

They are green in color because of the presence of chlorophyll. It is in chloroplasts that the chemical reactions of photosynthesis occur.

In addition, these structures have DNA, RNA and ribosomes, so they can multiply and synthesize proteins naturally.

Final answer:

A chloroplast is a type of plastid in plants that contains chlorophyll for photosynthesis. This process uses sunlight, carbon dioxide, and water to produce glucose and oxygen. The chlorophyll appears green because it absorbs blue and red wavelengths of light but reflects green.

Explanation:

The plastid with chlorophyll in plants that photosynthesize is called a chloroplast. Chloroplasts are plant cell organelles that contain a green pigment called chlorophyll, which captures the energy of sunlight for photosynthesis. This process involves a series of reactions that use carbon dioxide, water, and light energy to make glucose and oxygen.

Photosynthetic eukaryotes, including plants and some protists, possess these chloroplasts. However, some bacteria also perform photosynthesis, but their chlorophyll is not located in chloroplasts but instead, within the cell itself.

All photosynthetic organisms contain a pigment called chlorophyll a, which humans perceive as green. This is because it absorbs wavelengths from either end of the visible spectrum (blue and red), but not green, which is reflected, making chlorophyll appear green.

To classify an organism a scientist finds in the field, which of these will the scientist first compare to other known organisms?A. Dietary habits
B. Ecological niche
C. Physical structure
D. Reproductive method

Answers

The answer is C. Physical structure.

Different species can share dietary habits, ecological niches, and reproductive method although they are not related. So, classifying organisms based on these features is not helpful a lot. It is known that different species differ in DNA sequence. Since physical structures are determined by DNA sequences, physical structures could show in first sight difference between species. Therefore, to classify organism found in the field, the scientist will start from comparing its physical structures to the other known organisms.
