A pea plant purebred to produce round yellow peas is crossed with a plant purebred to produce wrinkled green peas. Round pea shape is dominant to wrinkled, and yellow pea color is dominant to green. Members of the resulting F1 generation are then crossed to produce an F2 generation, as shown in the figure. On average, what fraction of the F2 generation will display both dominant traits?

Answer: In ecosystems, matter and energy are transferred from one form to another. Matter refers to all of the living and nonliving things in that environment. Nutrients and living matter are passed from producers to consumers, then broken down by decomposers. Decomposers break down dead plant and animal matter.

Answer:

Due to presence of waxy layer.

Explanation:

A leaf cannot be tested for starch by adding iodine solution directly because waxy cuticle covering the leaves that prevents the penetration of iodine in the  leave cells. First, the waxy layer should be removed by boiling the leaves that causes disruption in the cell membranes that make easier for the iodine to penetrate in the leave cells so that's why iodine can not be tested for starch directly.

Answer:

c. Frame shift mutation.

Explanation:

Frame shift mutation is a type of mutation which causes more damage to the DNA of the cell. It causes changes in the amino acid sequences in a polypeptide chain. Point mutation is a type of mutation in which only one amino acid changed, while on the other hand, frameshift mutation changes the whole sequence of amino acids so we can say that frame shift mutation is more damaging to the DNA molecule.

Explanation:

Plant reproduction is important to people and animals also because if plants were not continuing to make more of themselves then there would not any plants for people and animals to eat. ... Plants and animals and plants and pollinators are interdependent because they all need each other to survive.

Answer:

like animals plants reproduce by there parent plant from seeds there is three ways plants reproduce from wind, water and animal

animals: animal like monkey eat the fruit of the plant and throw the seed away  later it will start growing

wind: when a strong winds occur it will carry plants like dandelions, swan plants away from its parents and when the wind is over it will start growing

water: plants like coconut will fall on the sea and plot away from its parent and after it landed on land it will start growing

Development of simple bacteria --> RNA formation --> DNA formation

Explanation:

The sequence of events best describes the current theory of the origin of life on Earth development of simple bacteria --> RNA formation --> DNA formation.

According to the hypothesis and researchers, it seems to confirm that RNA was the first genetic or hereditary material that was present in the simple form of bacteria developed first.

RNA is the molecule responsible for the origin of life on the earth and evolved all the required processes and methods for carrying and expressing the genetic information of an organism before DNA. DNA is evolved from RNA molecules of simple bacteria.

Nucleic acid is one of the biological molecules in living organisms. The two types of nucleic acids are DNA and RNA. DNA (deoxyribonucleic acid) is a double stranded biological molecule that stores genetic information in living cells. They are made up of monomers called nucleotides.

Therefore, The sequence of events best describes the current theory of the origin of life on Earth development of simple bacteria --> RNA formation --> DNA formation.

Answer:

The population history of the island remains highly controversial. In addition to internal conflict, the population crash has been attributed to “ecocide,” in which the Island's resources were exhausted by its inhabitants, reducing its ability to support human life.

Explanation:

Europeans was known to discovered Easter Island in 1722 and it's name was given by Captain Admiral Jacob Roggeveen.

The human population growth had a negative effect on the Easter Island.

The ecocide hypothesis is the one explanation to how the human population increased exponentially since its colonization and as such

Human populations did over increased the carrying capacity of the Island to support sustainable crops, and in consequence, the island was severely deforested.

The island's natural cycling of matter and energy also reduced or change and as such the people fought among themselves for scarce resources of the island. They had little food and were starving and they resorted to cannibalism.

The island was also plaque by blackbirding from 1862 to 1863.

Answer:

Explanation:

1 number label represents the cell membrane, materials moving into and out of the cell are controlled by the cell membrane, hence option A is correct.

A durable barrier between two aqueous compartments is formed by the phospholipid bilayer, which is the membrane's basic structural component.

They have receptors and channels that let particular molecules like ions, nutrients, wastes, and metabolic products that mediate cellular and extracellular activities pass between organelles and between the membrane.

Therefore, biological membranes are semipermeable and serve three main purposes, they prevent toxic substances from entering the cell, hence option A is correct.
