Which of the following statements is accurate?
Musya8 [376]

Answer: c. the wavelength of both transverse and longitudinal waves is measured parallel to the direction of the travel of the wave.

Explanation:

The wavelength is simply the distance that takes place between two successive troughs fir a particular wave. It is calculated as:

Velocity / Frequency.

From the statement given, the option that is accurate is that the wavelength of both transverse and longitudinal waves is measured parallel to the direction of the travel of the wave.

Name two primary decomposers and describe their function in the recycling of life materials 125 words.
Sloan [31]

Bacteria and Fungi  are the two primary decomposers

Explanation:

<u>Bacteria: </u>Bacteria are known as microscopic single celled organism. Their existence is between inside as well as outside the organism. The use of bacteria is in medical and industrial processes. They are first organisms in earth. Bacteria can survive in worst condition. There are huge number of bacteria. So, it is classified according to their structure and shape.

The life cycle of bacteria can be divided into log phase, lag phase, the stationary phase and Death phase. In lag phase bacteria don’t grow they produce amino acid and protein and make copies of DNA. They make themselves ready for division. In log phase bacteria rapidly multiply itself through binary fusion. In the stationary phase the growth of bacteria is dwindles because of lack of space and accumulating waste. The last phase is death phase where bacteria loss its ability of reproduction.

<u>Fungi:</u> Fungi is same like bacteria play vital role in ecosystem. They are also decomposer. The first way of fungi life cycle is based on spore phase. They begin with haploid. They have one copy of all their genetic material. The second stage is mycelium stage where fungi reproduce asexually.

dsp73

Answer:

The statement suggests ability of existing DNA molecule to replicate itself by the process of DNA replication. Each strand of double helical DNA can serve as template for the synthesis of new complementary DNA strand.

Explanation:

Watson and Crick proposed the double-helical structure of DNA. Accordingly, the DNA molecule is a double helical structure in which two polynucleotide chains are held together by base pairing between the complementary bases of two chains.  

There are four nitrogenous bases present in DNA: adenine and guanine (purines) and cytosine and thymine (pyrimidines). Adenine always pairs with thymine and cytosine pairs with guanine base.  

According to Watson and Crick, the ability of one DNA strand to base-pair with a complementary DNA strand suggests the existence of the DNA replication process. During DNA replication, each DNA strand should serve as a template to specify the nucleotide sequence of the new DNA strand.

Phagocytosis is exemplified by ______. phagocytosis is exemplified by _______. a cell manufacturing a substance that is first en
swat32

Phagocytes refer to the procedure by which some kind of living cells known as phagocytes engulfs or ingest other cells or particles. The phagocyte may be a free-living one-celled species, like an amoeba, or one of the body cells, like a white blood cell.  

In higher species, phagocytosis is mainly a defensive mechanism against infection and invasion of the body by the antigens, that is, foreign particles.  

Thus, phagocytosis is illustrated by most types of white blood cells ingesting bacteria, viruses, and other foreign substances.
