Sponges have collar cells that trap food and ingest it by or by the enzymes of lysosomes.

Answers

Answer 1
Answer: One type of organisms known as sponges have collar cells that trap food and ingest it by ___ or by the enzymes of lysosomes. The word that would best complete the sentence is "phagocytosis". This is also most commonly known as the food-eating that is the process of engulfing food.
Answer 2
Answer: The statement is correct. Sponges engullf food by the process of phagocytosis. The membrane fuses with the food and takes it inside, where they are acted upon by the food breaking enzymes, lysozymes, which convert food into simpler utilizable form. This process is most common in some unicellular organisms like sponges, and amoeba.

What is the number of chromosomes in a somatic cell of an organism  who has 52 chromosomes

Answers

The number of chromosomes in a somatic cell is  52 chromosomes as it undergo mitosis cell division.

What is somatic cell?

A somatic cell is also called as vegetal cell. It can make up an organism’s body.

In a multicellular organism all the cells are somatic cells except gametes, stem cells and germs cells,

These cells are involve in growth and development of an organism, also help in repair and regeneration.

In our body, there are about 220 types of somatic cells.

Many cells are differentiated to perform various specific functions. some examples of somatic cell types are skin cells, nerve cell, muscle cell, blood cell.

Somatic cells  have diploid set of chromosome and undergo mitosis and contain the same set of chromosomes. Hence, the somatic cell of an organism has 52 chromosome.

Which statement best describes a human influence on the biogeochemical cycles?increased eutrophication caused by high levels of nitrogen and phosphorousincreased nitrates available due to inaccurate methods of denitrificationincreased global warming due to alternative energy sources
increased amount of water that is available to freshwater ecosystems

Answers

The best statement would be increased eutrophication caused by high levels of nitrogen and phosphorous. Nitrogen and phosphorous are found in fertilizers. These fertilizers are used by farmers in croplands. Excess use of these might lead for the excess amounts to run off to water bodies which may cause eutrophication. Therefore, altering the nitrogen and phosphorous cycles.

Reword the following statement to make it true: Nucleoli are membrane-bounded structures present in the eukaryotic nucleus. A) Nucleoli are two lipid bilayers that surround nucleus in eukaryotic cells.
B) Nucleoli are large protein complexes that cross the nuclear envelope in eukaryotic cells.
C) Nucleoli are thin, dense meshworks of fibers lining the inner surfaces of the inner nuclear membranes of most eukaryotic cells.
D) Nucleoli are structures made of DNA, RNA, and protein that are present in the eukaryotic nucleus.

Answers

Answer:

Option-D

Explanation:

The nucleolus is a structure present in the nucleus of the cell which is important for the cell.

The nucleolus provides the site of transcription of the rRNA genes and the enzymes required for transcription. The nucleoli appear condensed structure as the rRNA genes, some portion of DNA and the proteins in the form of the enzymes like RNA polymerase I.Therefore, nucleoli are made of the DNA, RNA and the proteins.

Thus, Option-D is correct.

Answer: Option D  

Explanation:

The nucleolus is the largest structure which is found in the nucleus of the eukaryotic cells. It is the main site for the ribosome biogenesis.

Nucleoli consists of DNA and RNA, proteins and it forms around the nucleolar organizing regions. it also help in cell signaling.

These are like envelops which bounds the nucleus inside it. In case of the treatment of cancer, the main target is nucleolus.

In eukaryotic cells, the timing of the cell cycle is regulated by?

Answers

cyclin-dependent kinases, or CDKs. Cyclin-dependent kinases trigger the transition between cell cyclephases by phosphorylating substrates within the cell.
