How did Mendel make the F1 generation for his experiments?

Advocard [28]

<h3>Answer;</h3>

He crossed two pure breeds

<h3>Explanation;</h3>

F1 or the first filial generation is the first generation of offspring produced by crossing a set of parents to help show what genes will be inherited from crossing pea plants. Therefore, the F1 generation consist of or offspring from the parents.
Mendel performed a true breeding cross, meaning he crossed one homozygous recessive for a trait and one homozygous dominant for the trait. This gave rise to the heterozygous dominant offspring.

Naddik [55]

Answer:

A & B

Explanation:

Leucine and phenylalanine have hydrophobic side chains, which means that they can interact with valine in the pocket. All other aminoacids on the list have polar (two electrically charged) side chains and cannot form hydrophobic pockets.

Economic benefits of forest

omeli [17]

Forests play an important role in the economic development of a country. They provide several goods which serve as raw materials for many industries. Wood grown in forests serves as a source of energy for rural households.

Most of the world’s paper is made from wood and one rather reliable index to the degree of economic development of a country is its per capita consumption of paper. As an economy develops economically, paper is used as packaging material, in communications and in scores of other uses. No really satisfactory substitute for paper exists for many of its uses.

While it has long been recognized that forests play many roles in the economic development of a country in addition to providing wood fiber for many uses, the non-wood outputs of forests are coming increasingly to be recognized and valued everywhere in the world. Forests have watershed values especially in areas with fragile and easily eroded soils; tree cover may be highly valuable simply as protection to the watershed.

Forests are valued as a place for outdoor recreation. The kinds of forests most valuable for outdoor recreation are not always the same as the kinds most valuable for wood production and vice versa. The dense forest with trees closely spaced to take full advantage of the sunlight, moisture and fertility to grow wood, is often less attractive to the recreationist than a more open forest.

Forests are the home for many species of wildlife including mammals, reptiles and birds. Some of these forms of wildlife are clearly valuable to man. Ecologists have been much disturbed at the reduction in wildlife numbers, sometimes to the point of extinction, as tropical forests are cleared.

Members of the phylum ____ are considered by many researchers to be the living plants most closely related to vascular plants, b

DIA [1.3K]

Answer: The answer is Anthocerophyta

Explanation: Anthocerophyta are widespread and occur in the temperate & tropical zones. The species of plants in this phylum have horn-shaped sporophytes which are known as "flower horn". As in other bryophytes, the sporophyte of this phylum remains attached to its parent gametophyte throughout its life, but unlike these other plants, the sporophyte continues to grow throughout its life; this happens as a group of cells at the base of the horn divide repeatedly. They also possess stomates, which exchange gases between the plant and the air.

The mitochondrial genome evolution in Anthocerophyta is closer to that of seed plants but not as dynamic.
