It's C they help in reproduction, antibiotic resistance, virulence and competition with other bacteria.
Answer:
The functions of dendrites are to receive signals from other neurons, to process these signals, and to transfer the information to the soma of the neuron
Explanation:
<u>Answer:</u>
The most appropriate answer option is: D) Saprophytes return organic material to the soil for use by living organisms.
<u>Explanation:</u>
A saprophyte, also known as a saprobe or saprotroph, is an organism (fungi) which feeds and grows on decomposing organisms. We also know that it secrete enzymes that digest components of cell walls, such as cellulose and lignin.
Saprophyte is an important part of the biogeochemical cycle as it decomposes the bodies of the dead organisms, recycles them and releases nutrients into the soil to be used by the living organisms.
Metastasis will happen and cancer cells invade nearby healthy cells, tissues, lymph nodes, organs or will migrate to distant organs.
The two different types of stem cells broadly classified as are Embryonic stem cells and adult stem cells. Embryonic stem cells are obtained from the blastocyst layer of the embryo and are pleuripotent. Whereas adult stem cells are the undifferentiated cells from tissues of an adult or a child. They can be unipotent or multipotent.
Explanation:
Cancer cells migrate to other parts of the body via blood and lymphatic system. This is called as metastasis. Cancer cells when becomes tumour they develop their own blood vessels and obtain nutrients from them. Once the tumour gets big it pushes the normal healthy cells of the neighbouring tissues and keeps on spreading.
Stem cells obtained from the embryo can differentiate into any types of cell and when grown in-vitro can dramatically form the three germ layers.
The adult embryo cells are found in less quantity, their role is to repair the tissue they reside in.
Answer:
DNA is a polymer. The monomer units of DNA are nucleotides, and the polymer is known as a "polynucleotide." Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group.
