Why did Mendel study pea plants?

They reproduce asexually and have one trait that is easy to observe.
They reproduce asexually and have many traits that are easy to observe.
They reproduce sexually and have one trait that is easy to observe.
They reproduce sexually and have many traits that are easy to observe.

Answers

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.

Why did Mendel choose pea plants to study?

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.

What was the purpose of the pea plant study?

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.

During winter's freezing temperatures, some plants can remove water from their cells to reduce the amount of water that will freeze inside them. Why would plants need to do this

Answers

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

Which kind of organism is an autotroph? consumer producer decomposer herbivore

Answers

Answer:

Producer

Explanation:

An autotroph is a type of organism that is capable of producing its own food from inorganic substances. The correct answer is "producer."

Describe autotroph.

Autotrophs utilize various processes to convert energy into usable forms. The most common and well-known method is photosynthesis, which involves capturing sunlight and using it to convert carbon dioxide and water into glucose (a type of sugar) and oxygen. Plants, algae, and some bacteria are examples of autotrophs that perform photosynthesis.

They are often referred to as producers because they can convert energy from sunlight (or other forms of energy) into organic compounds through processes like photosynthesis or chemosynthesis.

Autotrophs, such as plants, algae, and some bacteria, are able to synthesize their own nutrients and energy sources, typically using sunlight, water, and carbon dioxide. They form the foundation of food chains and provide energy for other organisms in ecosystems.

Therefore, the correct answer is "producer."

How has the study of genetics shaped our understanding of heredity?

Answers

Genetics is the study of how heritable traits are transmitted from parents to offspring. Humans have long observed that traits tend to be similar in families. It wasn't until the mid-nineteenth century that larger implications of genetic inheritance began to be studied scientifically.

Staphylococcus aureus, or staph, is a bacteria that is commonly found in the nose and on the skin of humans. While it is typically not harmful to humans, it is sometimes able to enter the body through an injury or broken skin, and get into the bloodstream. When this happens, it can cause a serious infection called sepsis. Sepsis can cause an individual to go into shock and bodily organs to stop functioning. Symptoms of sepsis include inflammation, fever or hypothermia, increased heart rate, and rapid breathing.

Which parts of DNA provide the code for proteins?

Answers

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.

The DNA code contains instructions needed to make the proteins and molecules essential for growth, development and health.

What is gene?A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins.  Many genes do not code for proteins.

A girl is born with hemophilia. Her dad also has hemophilia, but her mother does not.

What genetic explanation can you provide as to why the girl
suffers from hemophilia?

Answers

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.
