Biology
1 answer:
Julli [10]3 years ago
6 0

Answer:

1. A producer is an organism that is capable of making its own food. For example, plants.

2. A consumer is an organism that cannot make its own food and hence fed on producers or other consumers. E.g humans

3. A predator-prey relationship is a relationship in which a predator organism eats a prey organism. For example, lion and zebra.

4.  Symbiosis is a biological interaction between organisms of different species.

5. Parasitism is a biological interaction in which one organism gains benefit and harms the other organism.

6. Commensalism is a biological interaction in which one organism gains benefit whereas the other organism neither gets harmed nor gains any benefit.

7. Mutualism is a biological interaction in which both the organisms benefit from each other.

8. A niche is the role which an organism plays in a community or an ecosystem.

9. The three types of symbiosis are Parasitism, Commesalism and Mutualism.

How is nitrogen metabolism in the prokaryotes vital to other organisms? given the roles of bacteria in the nitrogen cycle, how w
Murljashka [212]
Metabolizing nitrogen in prokaryotes is very important to other organisms since these prokaryotes are able to convert ammonium in the soil to nitrate and, then, the denitrifying bacteria could use the nitrate produced instead of using oxygen in their metabolism in order to release nitrogen molecules. by the denitrification process, thus completing the nitrogen cycle. Without the nitrogen metabolism in prokaryotes, the nitrogen in the atmosphere could not be used or utilized to synthesize essential organic compounds that are needed by other organisms. It is only the prokaryotes that has the ability fixing nitrogen or can do the process of nitrogen fixation.

Which list represents the proposed sequence in plant evolution?​
Phoenix [80]

Answer:

1. Bryofita

2. vascular plants

3. Seed vascular plants (gymnosperms)

4. Angiosperms

Explanation:

1. Bryofita

Around 475 million years ago, the origin of plants was thought to originate from aquatic ancestors (green algae). Adaptation to terrestrial life is proven by the presence of sporopolenin and layered gametangia that protect gametes and embryos. This adaptation occurs in bryophytes which are the first terrestrial plants. Bryofita or mosses develop into various vanations in their group. Most briolites do not have vascular tissue (water from the environment is diluted and absorbed by the SD, but some briophytes have water-carrying vessels.

2. Vascular plants

Around 400 million years ago, the evolution of plants was marked by the diversification of vascular plants (vascular plants). These early vascular plants are seedless plants, for example in the types of ferns seria into other groups of seedless plants.

3. Seed vascular plants (gymnosperms)

Plant evolution begins with the appearance of seeds, which are structures that protect the embryo from drought and the threat of environmental change. The emergence of these seed plants accelerated the expansion of plant colonization on land. Plant seeds consist of embryos and food reserves that are protected by a cover. Seed vascular plants appeared about 360 million years ago with the appearance of Gymnosperms. Gymnosperms consist of conifers with a variety of types. Conifers and ferns dominate life in the months between more than 200 million years.

4. Angiosperms

About 130 million years ago marked the emergence of flowering plants that have a somewhat reproductive structure

complicated where the seeds are protected by a room called the ovary.Because the seeds are protected in such a way that this group discusses closed seed plants or Angiosperms

Answer:

The needed options are

A. an uncontrolled experiment

B. intuitive reasoning

C. extrapolation

D. replication

E. exploration

The ANSWER is D. replication

Explanation:

Replication in research means using the same method and methodology in proximity to the original research work.

It helps in bringing, validating and proving the original study is up-to-date. It may be done using the same exact methods in a different cultural settings, location or different research subjects to determine if the original experimental results is up-to-date.

Volgvan
Bile

Based on the above symptoms, it can be inferred that Gloria lacks bile. Pain in the upper right portion of the abdomen usually corresponds to problems with the liver. The liver produces bile (also known as gall), which is a dark green to yellowish brown fluid that helps most vertebrates with digestion. It increases the absorption of fats and fat-soluble substances such as vitamins A,D,E, and K. It is also necessary for the excretion of bilirubin, which is a byproduct when red blood cells are recycled by the liver. 

Bile deficiency can cause the fats in the food to be undigested and these fats end up excreted as part of feces. It can also lead to vitamin deficiency and a gradual build-up of toxins in the liver.
