HELP!!! MAJOR GRADE!!!!!

Gregor Mendel conducted thousands of genetic experiments using pea plants. Mendel is called the Father of Genetics because it was these studies that lead to the principles of genetics. In one of his many experiments, he crossed purple-flowered pea plants with white-flowered pea plants. Much to his surprise, all of the offspring turned out to be peas with purple flowers in appearance.

Although Mendel used the term factors instead of genes, how did Mendel explain why all the pea plants had purple flowers and not a mixture of white and purple flowers?

A.The offspring received the factors (genes) from both parents, but the genotype for purple flowers dominated over white flower pea plants.

B.The offspring only received the factors (genes) from the parent with the genotype for purple flowers and nothing from the white flower parent.

C.The offspring received the factors (genes) from both parents, but the phenotype for purple flowers dominated over the factor for white flowers.

D. The offspring only received the factors (genes) from the parent with the phenotype for purple flowers and nothing from the white flower parent.

Answers

Answer 1

Answer:

A

Explanation:

The purple gene was dominant, so though the plants got "factors" from both parents, only the purple gene was expressed in their phenotype (purple petals).

Identify 3 uses of ATP in a cell

Answers

Answer:

ATP is consumed for energy in processes including ion transport, muscle contraction, nerve impulse propagation, substrate phosphorylation, and chemical synthesis

Explanation:

Adenosine triphosphate (ATP) is a small molecule that acts as a coenzyme within a cell.

The main role of ATP is to provide energy. Below are the ways it provides energy which can described in an exam.

1) A source of energy.

2) An ATP molecule releases approximately 30kJ (mol^-1) of energy

3) Energy from an ATP molecule is released in small quantitites to prevent damage to the cell

4) Energy released is used for metabolism in the cell. Other reactions that require energy from ATP include; active transport/ muscle contraction/ glycolysis.

what is the function of RBC

Answers

Answer:

When a red blood cell is placed in a hypertonic solution, it contracts as water is drawn out of the cell and into the surrounding solution. If the same blood cell is placed in a hypotonic solution, the blood cell grows in size. Blood cells in isotonic solutions do not shrink or swell.

The reason that blood cells change in size when placed in a solution with different salt concentration is due to the osmosis process. Osmosis causes solutions with high concentrations of salt to draw water from areas with low concentrations of salt.

There are some exceptions to this phenomenon. Blood cells can draw water and explode when placed in hypertonic solution on some special occasions. Some diseases affect the structural integrity of blood cells. Also, when human blood cells are exposed to temperatures close to freezing, they can draw water and explode.

Osmosis is an important phenomenon for living systems. The amount of salt in a given solution exhibits a tendency to diffuse through the environment, eventually resulting in equilibrium. In addition to blood cells, the kidneys function through the use of osmotic principles. The kidneys filter an animal's blood to remove excess salt and balance the amount of water

The cells of a plant help the plant maintain its life functions. What part of a plant cell has the function of producing sugar in the presence of sunlight?

Answers

Answer:

CHLOROPLAST

Explanation:

As stated in this question, plant cells are capable of producing their own food in form of sugar (glucose) using energy from sunlight in a process called PHOTOSYNTHESIS. Photosynthesis is the process by which green plants and other certain organisms synthesize their own food using light energy.

The ability to carry out this photosynthetic function is embedded in a structure found in plant cells called CHLOROPLAST. Chloroplast contains a pigment called CHLOROPHYLL, which captures light energy from the sun. Generally, the the function of producing sugar in the presence of sunlight (photosynthesis) occurs in the CHLOROPLAST.

Ruby has observed that plants in her garden vary in height. She wants to investigate whether a plant species (species A) grows faster than the other garden species (species B, C, and D). Select the statement that describes Ruby gathering enough evidence to support a scientific explanation concerning plant growth rates

Answers

Answer:

This question lacks options, the options are:

A) Ruby measures the heights of several species A, B, C, and D plants for a week under different conditions and finds a journal article that describes the growth rate of species A.

B) Ruby measures the height of a species A plant for a week and finds an anonymous gardening blog that describes the growth rate of species A.

C) Ruby measures the heights of several species A, B, C, and D plants for a week under the same conditions.

D) Ruby measures the heights of several species A, B, C, and D plants for a week under the same conditions and finds journal articles that describe the growth rates of each species.

The answer is D

Explanation:

According to this question, Ruby wants to investigate whether a plant species A in her garden grows faster than other plant species (B, C and D) due to the varying height she observed in them. To do this, Ruby will need to conduct a scientific investigation by measuring the height of all the plant species she is trying to compare (A, B, C, D).

However, she must do the measurements under the same conditions i.e. controlled in order not to influence the result. In order to make a scientific explanation concerning the plant growth rates, Ruby should find journal articles that describe the growth rates of each species and make comparison with her experimental/measured height values.

Na and Ca have an equal number of valence electrons. C. Na has one more valence electron than Ca. D. Na has one fewer valence electron than Ca.

Answers

Answer:

D. Na has one fewer valence electron than Ca.

Explanation:

Elements in different groups has been grouper based on the number of valence electrons they possess. Valence electrons refers to the electrons at the outermost part of the shell of an atomic element.

Sodium (Na) belongs to group 1 on the periodic table meaning that it has one number of valence electrons while Calcium (Ca) belongs to group 2 meaning that it has two number of valence electrons. Hence, Na has one fewer valence electron than Ca.

Answers

Answer:

A reduction in predators

Explanation:

I just took the test

A reduction in predators could explain the curve in this population growth graph.

How does reduction in number of predators lead to curve?The prey species soon degrades and overruns its area since there are no predators to regulate the population and modify feeding behavior.When food becomes scarce, people grow unwell and famished, and they either flee or crash.When predator populations grow, putting more pressure on prey populations and acting as a top-down control, pushing them toward extinction. As a result, the size of prey populations is influenced by both resource availability and predation.
