What is ecological succession?
A. Change that happens over time in an ecological community

B. A way a life

C. One person giving another person power

Answers

Answer:

A. Change that happens over time in an ecological community

Explanation:

Ecological succession is the change that happens over time in an ecological community. So, option (A) is the answer.

Answer:

A. Change that happens over time in an ecological community

Explanation:

Ecological succession is the gradual process by which ecosystems change and develop over time. Nothing remains the same and habitats are constantly changing.

There are two main types of succession, primary and secondary.

Primary succession is the series of community changes which occur on an entirely new habitat which has never been colonized before. For example, a newly quarried rock face or sand dunes.

Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat. For example, after felling trees in a woodland, land clearance or a fire.

Which of the statements regarding the nitrogen cycle is true? a. Denitrification occurs when a nitrogen containing compound is produced from nitrogen in the soil. b. Atmospheric nitrogen is absorbed through the leaves of plants. c. Nitrogen fixation is the process atmospheric nitrogen is converted into biologically usable forms. d. Animals obtain nitrogen through the process of cellular respiration

Answers

Answer: Option C

Explanation:

The nitrogen cycle can be defined as the process by which the nitrogen is being recycled. The nitrogen is transferred from the atmosphere to the plants and then from plants to animals, human beings.

Then from animals and human beings it is again transferred into the soil and then atmosphere.

The nitrogen that is found in the sol is not in the usable form by the plants, nitrogen fixing bacteria converts it into usable form.

What does the theory of evolution tell us about living things?

A) The environment can make them change rapidly over a short period of time. B)They create fossils when they die
C)Their environment makes them change slowly over time.
D)They can give us clues about extinct species. (science 7th grade) (100 POINTS)

Answers

Answer:

Their environment makes them change slowly over time

Explanation: I took the test and got it correct.

The agents of wethering erosion deposition and the rock cycle will slowly change the fossils over time. They may damage them or burry them deep into the layers of earth. Over time, as they age, new landforms will me made ontop of them. This is why they use the fossils to determine the age of the land. I hope this helps :)

When might self-fertilization be beneficial for a plant? When there are too many dioecious individuals in a population, self-fertilization becomes beneficial for a monoecious individual. When environmental conditions are harsh, such as a plant growing in nutrient-poor conditions, or when herbivores have damaged the plant, plants may self fertilize. When environmental conditions are perfect, plants can afford to self-fertilize. Only plants with perfect flowers are capable of self-fertilization.

Answers

Answer:

Only plants with perfect flowers are capable of self-fertilization.

Explanation:

Self-pollination is the process that allows plants to fertilize themselves. This process is very beneficial when a plantation has plants with few flowers or when the plants are spaced far apart.

However, only plants with perfect flowers can self-fertilize. This is because for self-fertilization to occur, the plant needs to have flowers that present the male and female reproductive organs, which allows the same flower to produce pollen that will be sent to its own ovary. Only perfect flowers have male and female reproductive organs at the same time.

What is viruse ?

A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898, more than 9,000 virus species have been described in detailof the millions of types of viruses in the environment.Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. The study of viruses is known as virology, a subspeciality of microbiology.

When infected, a host cell is often forced to rapidly produce thousands of copies of the original virus. When not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent particles, or virions, consisting of

(i) the genetic material, i.e., long molecules of DNA or RNA that encode the structure of the proteins by which the virus acts;

(ii) a protein coat, the capsid, which surrounds and protects the genetic material; and in some cases

(iii) an outside envelope of lipids. The shapes of these virus particles range from simple helical and icosahedral forms to more complex structures. Most virus species have virions too small to be seen with an optical microscope and are one-hundredth the size of most bacteria.

1.DNA is a molecule composed of two chains in form a ____________ compose by______________, ____________ and pentose. And the structure and function of genes.

Answers

Answer:

DNA is a molecule composed of two chains in form of a DOUBLE HELIX compose by ORGANIC NITROGEN CONTAINING BASE, PHOSPHATE GROUPS and PENTOSE.

Explanation:

Nucleic acids are found in all living cells. They are composed of strands made up of repeating units called nucleotides. Each nucleotide consists of

--> a five carbon sugar( PENTOSE)

--> a phosphate group

--> an organic nitrogen containing base: adenine, guanine, cytosine or thymine.

The two types of nucleic acids include:

--> Deoxyribonucleic acid ( DNA) and

--> Ribonucleic acid ( RNA)

Deoxyribonucleic acid ( DNA) is found in chromosomes located in the nucleus of cells.

STRUCTURE OF DNA

The DNA molecule consists of two strands that curve spirally to form a double helix structure. The strands are held together by hydrogen bonds between the base side arms. Each base on one strand will only pair with a specific base on the other strand: hence guanine will only pair with cytosine and adenine with thymine.

FUNCTIONS OF DNA

It stores the organism's hereditary traits and directs the day to day metabolic activities of each cell in the organism.
