Explain Mendel's law of segregation and how it predicts the 3:1 dominant-to-recessive phenotypic ratio among the F2 generation o

f a monohybrid cross.

Olenka [21]3 years ago

Answer:

Mendel is known as the father of genetics. He explained the law of segregation by the monohybrid cross. The monohybrid cross involves the cross of a single trait at a time.

Law of segregation explains that at the time of formation of gametes, the allele pairs get separated from the pairs of trait. The concept of dominance was also explained. The traits that express itself even in the heterozygous condition is known as dominant trait (T). The trait that can not express itself is known as recessive trait (t).

For example:

Parents TT        ×       tt.   (Laws of segregation)

Gamete   T                  t

F1 generation  Tt.

Selfing of F1 generation

Tt       ×        Tt

Offspring :   TT (tall) , Tt (tall) , Tt (tall) , tt (dwarf).

The phenotypic ratio is tall : dwarf (3 : 1)

In what way are pathogens similar to hormones and enzymes?<br> Can Somebody please help me thx :D
Serjik [45]

Background research to note if your unsure what some terms mean/are:

  • Hormones and Enzymes play a vital role in our body by controlling and regulating many functions.
  • Hormones are known as chemical messengers as they trigger many functions
  • Enzymes are catalysts as they affect the rate of a reaction
  • A Pathogen is a bacterium, virus, or other microorganism that can cause disease.

Answer:

Although something that is similar with all is all can trigger, control, and affect the body in some way.

Hope this helps!!

Consider this animal cell. What is the function of the organelles that are labeled F? to temporarily store water, waste products
Temka [501]

The organelle labeled 'F' in the given diagram is Endoplasmic reticulum. The main function ER is to move proteins and other substances through the cell.

Further Explanation:

In biology, Endoplasmic Reticulum (ER) is a continuous membrane system that makes a series of flattened sacs inside cytoplasm of the eukaryotic cells and provides multiple functions. All the eukaryotic cells consist of endoplasmic reticulum. On the basis of their functional and physical characteristics they are divides into two types:

  • Smooth endoplasmic reticulum: They do not consist of any ribosome and synthesize lipids.
  • Rough endoplasmic reticulum: they consist of the ribosome on their outer surface because of this their surface is rough. They help in synthesizing protein.

Important functions of the ER are:

  • Synthesis protein
  • Protein folding
  • Protein modification
  • Transport of protein

Golgi apparatus is a folded membranous structure present in eukaryotic cells and has vital intracellular functions. It has flattened sacs in the membrane which are referred to as cisternae. ER synthesizes protein and transfers it to the Golgi apparatus.

What is cpr what should the rate and oxygen?
dimaraw [331]
CPR is short for cardiopulmonary resuscitation. It’s a life saving medical procedure which is given to someone who is in cardiac arrest. It helps to pump blood around the person's body when their heart can’t. To carry out CPR a person presses up and down on the casualty’s chest (chest compressions<span>) and gives them a series of rescue breaths to help save their life when they are in cardiac arrest. At 6 min, CPR was started with an automated chest compressor at a rate<span> of 200-240/min.

Your group is conducting an experiment to test the effect of Earth's gravity on objects of different masses. Your group drops fo
natta225 [31]

Answer:

A) The paper is affected by air resistance due to its flat shape, so wadding the paper into a tight ball would cause it to hit the ground at the same time as the other objects.

Explanation:

<u>I am so sorry if this is incorrect! But after some research, this is what I found. </u>

Aristotle said that there are 4 elements: Earth, Wind, Water, Fire. Objects made of earth (like a rock) will want to go the center of the universe (center of the Earth). Things made of fire want to go to the place where fire is. I guess this would be the Sun - or somewhere up. Aristotle also said that a heavier object will fall at a faster speed.

Here is the first classic example. This is a bowling ball and a basketball dropped from the same height. Normally, people would assume thatn the bowling ball would drop quicker. They are correct. Please note that heavier objects do not always fall faster though.

I hope I answered your question! please give brainliest!
