Why is this relationship between a plant and bacteria called a mutualism?
belka [17]
Mutualism is relationship that is beneficial to both organisms involved. The relationship between a plant and a bacterium called a mutualism because both of them help each other. Bacteria are involved in increasing the fertility of the soil by fixing atmospheric nitrogen and thus provide plant with nitrogen. In return, the bacteria make their homes in what usually become nitrogen "nodules" along plant roots. The plant gets food, the bacteria gets shelter, everybody wins.

ZanzabumX [31]

Answer:

If these were the missing choices:

A) Positive, since it is needed for the local bird population.

B) Negative, since it is destroying much of their environment.

C) Positive, since it is a sustainable plan to use a renewable resource.

D) Negative, since it is a sustainable plan to use a renewable resource.

My answer would be: C) Positive, since it is a sustainable plan to use a renewable resource.

Renewable source is defined as resources that can be replenished overtime by natural processes. Farming trees is one of the processes that produces renewable sources.

After fertilization a zygote forms. The cells then go through mitosis. Explain how this bundle of cells eventually forms a human
yaroslaw [1]

Answer:

Human fertilization and development

Fertilization is the process in which haploid gametes fuse to form a diploid cell called a zygote. To ensure that each zygote has the correct number of chromosomes, only one sperm can fuse with one egg.

Stages of human development

Zygotic stage: The zygote is formed when the male gamete (sperm) and female gamete (egg) fuse.

Blastocyst stage: The single-celled zygote begins to divide into a solid ball of cells. Then, it becomes a hollow ball of cells called a blastocyst, attaching to the lining of the mother's uterus.

Embryonic stage: The major internal organs and external features begin to emerge, forming an embryo. In this stage, the heart, brain, and spinal cord become visible. Arms and legs start to develop.

Fetal stage: Once the formed features of the embryo begin to grow and develop, the organism is considered a fetus. Differentiation and specialization of structures happens during this time.

Differentiation and apoptosis

During development, the number of cells must increase through division so that body axes, tissues, organs, and structures must form. Individual cells become specialized in their structure and function through the process of cell differentiation.

Unnecessary cells also must be removed in order to help form important structures. This occurs is through the process of apoptosis. For example, human hands start out as a paddle-like block of tissue. Eventually, the block was “carved” into fingers by apoptosis of the cells in between the developing fingers.

What other factors would a forensic anthropologist have to consider when using bones to estimate the height of an individual fro
jarptica [38.1K]

Many of the skeletons have associated age, sex, ancestry, and cause of death data. Individual remains with known biological information are especially valuable references. Forensic anthropologists have used these skeletons to develop standards for determining sex, age and ancestry in unknown remains
