Which of the following pairs of agricultural types occupies the largest percentage of the world’s total land area? Plantation ag

Nonamiya [84]

Answer:

The correct answer is the letter D. Intensive rice cultivation

Explanation:

Subsistence agriculture is characterized by low technical level in small production units with the objective of directly feeding family members. Examples of low-intensity agricultural activities are carried out on small and medium-sized farms, usually with family labor. It occurs in low-valued areas, which do not interest commercial agriculture, however it is practiced worldwide. On the other hand, rice is the third most planted crop in the world, with approximately 160 hectares cultivated per year.

5.Write observation and conclusion of each of the following activities

Tomtit [17]

Answer:

Water puts pressure depends on their amount.

Explanation:

On the left side, there is less quantity of water in the tube that put less pressure on the bag present at the bottom and the bag swells slightly while on the other hand, on the right side, there is more amount of water in the tube that puts large pressure on the bag located at the bottom and as a result it swells higher than the other bag so we can conclude that more water puts more pressure and less water puts less pressure.

Mitochondrion; crista Mitochondrion; crista Mitochondrion is a constituent part of crista. Crista is a constituent part of mitoc

Leno4ka [110]

Answer:

1. b. Crista is s constituent part of mitochondrion.

2. c. Gobi complex and nucleus are separate structures with no particular relationship to each other.

Explanation:

The crista is an integral part of the mitochondria. As you already know, mitochondria is a cytoplasmic organelle. it has two members that delimit it, the outer membrane is completely smooth, however the inner membrane is composed of numerous folds, that are called crista, and that spread through the interior of the mitochondria. These crista have as main function to increase the surface of the inner membrane.

The Golgi complex is a cytoplasmic organelle, as is mitochondria. The nucleus, however, is a cell structure, it is totally separated from the golgi complex and there is no particular relationship between these two structures.

The golgi complex participates in the storage and distribution of substances in the cell, while the nucleus is responsible for housing and protecting genetic information.

3. There is a gene that affects pea pod color and has two alleles: G = yellow and g = green. There is another gene that affects

Lena [83]

A. Mendel in his experiments used two true breeding plants that only express one particular trait. He would chose plants with different versions of the trait and cross pollinate them. So, in this case, Mendel’ s P generation would be:

P: GGWW x ggww

B. The possible gametes produced by these first or original parent plants (GGWW and ggww genotypes of the parents) are:

GW and gw. When an organism makes gametes, each gamete receives just one copy of the gene, which is selected randomly (Mendel’s law of segregation).

C. If the gametes GW and gw are joined, the genotype in the offspring would be GgWw. This is dihybrid organism because it is heterozygous (have two different allelss, one recessive, one dominant) at two different genetic loci, G and W. The offspring represents the F1 generation.

D. If the individuals with the genotype GgWw are crossed with the individuals with the same genotype (GgWw), the possible gametes are GW, Gw, gW, gw. The possible genotypes for the F2 generation are: GGWW, GGWw, GgWW, GgWw, GGww, Ggww, ggWW, ggWw and ggww. There are nine different genorypes. The genotypic ratio is 1:2:2:1:4:1:2:2:1.

E. F2 generation of offspring of this dihybrid cross has a 9:3:3:1 phenotype ratio. Mendel did similar experiment with his plants and conluded that the pairs of traits in the parental generation (P generation) sorted independently from one another, from one generation to the next.

Explain the concept of growth using these terms: differentiate, meristem, elongation, and vascular cambium.

egoroff_w [7]

Answer: Well for one, Differentiate is when a cell matures and is used in a specific function. Meristem is a cell which never differeates and constantly divides so it is a mitotic cell. Elongation is the plant growing length wise therefore the meristem elongates the plant. Vascular cambium is the cambium which starts out in vascular bundles of the plant and then grows to form a ring inside the stem of plants that live for more than year- it causes and increase in thickness of the stem and branches.

hope this helped luv :)
