Frogs have 13 pairs of chromosomes. Complete this model by writing in the correct number of chromosomes for the sperm, egg, and fertilized egg of a frog. Then write in the type of cell division taking place in the two phases shown in the model.

Answer:

A. 0

B. 1/2 or 50%

Explanation:

Let us assume that the sickle cell anemia trait is represented by s and the alternate normal version by S.

Mary, a carrier would have the genotype Ss.

Mike, a perfectly normal person would have the genotype SS.

If both Mary and Mike marry:

                     Ss     x     SS

offspring: SS    SS    Ss    Ss

(A) In order to have sickle cell, the two alleles must be recessive. None of the offspring from the cross has two recessive alleles. Hence, the chances of Mary and Mike having a sickle cell child is zero.

(B) From the cross, two out of four of their potential offspring have the trait in heterozygous condition. Hence, the chances of Mike and Mary having a child who is a carrier is 1/2 or 50%.

Answer:

The genetic code is the sequence of nucleotide bases in nucleic acids (DNA and RNA) that code for amino acid chains in proteins. DNA consists of the four nucleotide bases: adenine (A), guanine (G), cytosine (C) and thymine (T). RNA contains the nucleotides adenine, guanine, cytosine and uracil (U).

A gene is a section of a DNA molecule that contains the information to code for one specific protein.

DNA is the genetic material, which is involved in carrying the hereditary information, replication process, mutations, and also in the equal distribution of DNA during the cell division.

lymphocytes is the answer

Answer:

#1, #2, and #4 are all true. #3 is false

Explanation:

answer:

So daughters get 2 X chromosomes from the mom and dad and if the dad has hemophilia the daughter would get it too and sons would not get because they get Y chromosome from their dad and hemophilia is found in the X chromosome because the X chromosome is the one that has the instructions for making the clotting factor proteins.

Explanation:

A father who has hemophilia has the gene and passes it on to his daughter because daughters get two X chromosomes, one from their mother and the other from their father. This is why daughters of men with hemophilia are called obligate carriers. Since sons only receive a Y chromosome from their father, they would not have inherited hemophilia.

The best example that shows the levels of organization in a multicellular organism from the smallest level to the largest is cell, tissue, organ, organ system, organism. Thus, option B is correct.

Cell theory is a scientific theory that's help to learn how living organisms are made up of cells, that's they are the basic structure unit of all organisms, and that all cells from pre-existing cells.

Prokaryotic cells are single-celled microorganisms known to be  earliest on earth.Eukaroyotic cell have a nucleus enclosed within the nuclear membrane and form large and complex organism.

Difference between unicellular and multicellular.

The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialised it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.

Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.

In unicellular organism division of labour is at the organ level on the other hand in multicellular the division of labour at cellular, tissue, organs and organ system level. Unicellular organism has simple body organization and multicellular organism have complex body organism.

Therefore,the best example that shows the levels of organization in a multicellular organism from the smallest level to the largest is cell, tissue, organ, organ system, organism. Thus, option B is correct.

Answer:

The expansion of excess water as it turns to ice inside the cells would break the cells apart

Explanation:

We know that water expands anomalously. It expands between 4- 0°C.

Hence water expands upon freezing. Ice has more volume than liquid water and takes up more space in plant cells.

The expansion of excess water as it turns to ice inside the cells would break the cells apart

Answer:

C

Explanation:

ight provides the energy for breaking apart sugars into small molecules. ... They absorb sunlight and transfer the energy to electrons. They form ATP as hydrogen ions cross the thylakoid membrane

Light provides the energy for making small molecules into sugars.

The correct option is B.

Photosynthesis is the process, by which plants make their food.

The process of photosynthesis is

carbon dioxide and water combined with the help of light to produce glucose and oxygen.

Answer:  

Determining bar temperature on Fahrenheit scale -

The temperature of the bar is given as 50 degrees Celsius.

If we know the temperature on the Celsius scale, we can convert it to the Fahrenheit scale.

We know

C / 5 = (F-32) / 9; Where C is the temperature on the Celsius scale and F is the temperature on the Fahrenheit scale.

Now,

50/5 = (F-32) / 9

Or, (F-32) / 9 = 10

Or, F-32 = 90

Or, F = 90 + 32

Or, F = 112 degrees Fahrenheit.

That is, the temperature of the bar on the Fahrenheit scale is 112 degrees Fahrenheit

Answer:

For Gregor Mendel, pea plants were fundamental in allowing him to understand the means by which traits are inherited between parent and offspring. He chose pea plants because they were easy to grow, could be bred rapidly, and had several observable characteristics, like petal color and pea color.

Explanation:

Gregor Mendel chose the pea plants for his experiments because the garden pea is an ideal subject in the study of genetics for the following reasons: The presence of observable traits with contrasting forms. It produces many offspring in one cross. Short life cycle.

Solution: Pea plants were chosen for Mendel's experiments because they are easy to grow, have a short life period, and produce larger flowers. Pea plants are also self-pollinated.

Gregor Mendel describes his experiments with peas showing that heredity is transmitted in discrete units. From the earliest time, people noticed the resemblance between parents and offspring, among animals and plants as well as in human families. Gregor Johann Mendel turned the study of heredity into a science.
