which is not true about the first 22 pairs of chromosomes in a karyotype
they determine the gender of the individual
each pair has one chromosome from the father and one from the mother
they are called autosomes
they are homologous meaning each pair has the same size shape, and collection of genes
Answers
Answer:
The correct answer is - they determine the gender of the individual.
Explanation:
Autosomes are the chromosomes that are numbered or non-sex chromosomes. In humans, there are 22 pairs of autosomes that are numbered from 1 to 22. These chromosomes regulate or control the pattern of inheritance of every characteristic or trait of an organism other than present on the sex chromosomes.
These are homologous chromosomes which means each pair has the same genes and has a similar shape. The gender of an individual depends on the sex chromosome only.

In a certain species of plant, the allele to produce green melons (G) is dominant over the allele to produce yellow melons (g). A student performed a cross between a plant that produced green melons and a plant that produced yellow melons. When the student observed the next generation, the 94 seeds that were produced from the cross matured into 53 plants with green melons and 41 plants with yellow melons. Calculate the chi-squared value for the null hypothesis that the green-melon parent was heterozygous for the melon-color gene.
Answers
Answer:
4.26
Explanation:
Let the green-melon parents be Gg, then we expect the cross with the yellow-melon plant gg so as to produce 50% Gg and other 50% of gg offspring. What we observed was that 53 green and a 41 yellow. Based on the total number of 94 offspring , we expected half and a half ratios to be 47 of each color.
Observed(o) Expected(e) (o-e) [tex]$(o-e)^2$[/tex] [tex]$(o-e)^2/e$[/tex]
Green-melon plant 53 47 6 36 0.766
Yellow-melon plant 41 47 -6 36 0.766
Therefore the chi-square value is 1.53 which is less than the critical value of 3.84. Therefore, the null hypothesis is accepted.

Answers
The process of binary fission work as 'one cell splits into two cells with identical DNA. in the asexual reproduction of bacteria'.
So, option B is correct one.
What is binary fission?The simplest meaning of binary fission is division into two. The binary fission is the most common methods of asexual reproduction.In biological , division of single entity into two or more parts and regenerates of these parts again and each parts have potential to grow to the size of the original cell.Binary fission occurs in Amoeba which is unicellular organismThe binary fission is type of asexual reproduction.What is asexual reproduction of bacteria

The blue people of Troublesome Creek Kentucky were genetically isolated from the rest of the world for generations. A rare recessive allele that causes people to have a blue tone to their skin, methemoglobinemia, became disproportionately common within this population by way of their genetic isolation. In the last few decades new roads opened leading to the end of this communities isolation. To the surprise of many, the methemoglobinemia phenotype disappeared along with their genetic isolation. Which of the following may best explain the apparent disappearance of this once common trait?
a. Methemoglobinemia did not confer any physical advantage so that the trait was selected against.
b. Methemoglobinemia was probably lethal and all those that carried this trait died and did not have a chance to pass on this trait to future generations.
c. Those that had the traits simply did not have descendents.
d. With the end of genetic isolation gene flow took place.
Answers
Answer:
The correct answer would be - d. With the end of genetic isolation gene flow took place
Explanation:
It is given that people of Troublesome Creek Kentucky were isolated and have a rare recessive allele that results in a blue tone to their skin. However, later these isolated people connected with the people from outside, and due which allow them to intermate. Intermating among populations from isolated and people from outside leads to gene flow.
Methemoglobinemia was present in the isolated population as they had both recessive alleles in their genotype and other hand people from outside might have heterozygous or both dominant allele genotypes that make them free from this disorder.
Due to the intermating and gene flow, the number of heterozygous conditions rises and after many generations slowly methemoglobinemia could have disappeared due to the masked recessive allele.

o You have encountered G-protein coupled receptors in Intro Bio I lecture, and will encounter them briefly again in Intro Bio II. You will spend 2 or 3 lectures on them in Cell Bio. They are integral (transmembrane) proteins embedded in the plasma membrane of every eukaryotic cell in your body. We will treat them as being 50 Angstroms in diameter. Considering the plasma membrane scaled up to the 4-inch baseline of the worked example in the lab powerpoint, how large would the G-protein coupled receptor be
Answers
Answer:
2 inches
Explanation:
Given that
The actual thickness of plasma membrane = 10 nm =10 * 10^-9 m
Diameter of G-protein = 50 * 10^-10 m
first step; determine the ratio of the actual thickness to the diameter of G-protein
= ( 10 * 10^-9 ) / ( 50 * 10^-10 )
= 2 ( this shows that the thickness of plasma is twice the diameter of the G-protein) .
considering that the plasma membrane is scaled up to 4 inch
The G-protein coupled receptor will be = 4 / 2 = 2 inches

The description best describes a squamous-shaped cell, a cell that is taller than it is wide a spherical-shaped cell a flattened, scalelike cell. The correct option is C.
What is a cell?
A cell is the basic unit of life. It is the smallest unit from which all living matter is made up of. It contains cell organs, and it performs many functions of the living bodies.
Cells are of different types and different shapes. Squamous-shaped cells are flattened, thin cells, and their nuclei are oval-shaped due to less space. They are called squamous epithelial cells.
These types of cells are present in the layers of skin and alveoli of the lungs. They help in passive diffusion.
Thus, the correct option is C. a flattened, scalelike cell.

A.)Ethylene
B.)Auxins
C.)Acids
Auxin moves to the darker side of the plant, causing the cells there to grow larger than corresponding cells on the lighter side of the plant. This produces a curving of the plant stem tip toward the light, a plant movement known as phototropism. Auxin also plays a role in maintaining apical dominance
