What would be the magnification of a specimen viewed with a compound light microscope that has an objective power of 100x and an ocular lens power of 10x

Answers

Answer 1
Answer:

Therefore, a 10x eyepiece used with a 40X objective lens, will produce a magnification of 400X. The naked eye can now view the specimen at a magnification 400 times greater and so microscopic details are revealed. More on objective lenses here. Magnification is the ability to view an object as larger.

In contrast to eukaryotic cells, prokaryotic cellsA. have a cell cycle that includes interphase and mitosis.
B. have to pass through the G1, S, and G2 phases to prepare for division.
C. have to use binary fission to divide.
D. have to go through prophase, metaphase, anaphase, and telophase.

Answers

The right answer is C

"Binary fission" is the most common form of reproduction and cell division of prokaryotes. A cell, after replicating its genetic material, divides into 2, each part containing a copy of the genetic material and 2 new perfectly individualized cells are finally created, each having the ability to grow to the size of the parent cell of origin ... The chronology is as follows:

- replication of the bacterial chromosomal DNA and segregation into two nucleoids and cell growth phase;

- assembly of a protein ring of constriction;

- constriction of the ring associated with the wall synthesis until complete individualization of the 2 new cells.
the answer to this is C.

What is the Breaking down of amino acids into urea and uric acids?

Answers

The breakdown of amino acids into urea and uric acids take place in the urea cycle, a biochemical process. 
Aspartate directly donates a nitrogen atom from the formation of urea during the urea cycle.
The argininosuccinate synthase reeaction links aspartate and citrulline via the amino group of aspartate and provides the second nitrogen of urea.
The breaking down of amino acids into urea and uric acids is called Catabolism; from organelles to cells to blood circulation by amino acid transporters. Then, it goes to the liver and the kidneys in the degradation of the amino acid. After the urea cycle; it will then be excreted in the form of urea.

Which of the following is most important in classifying two groups of bears into the same genus?A. similar diets
B. similar genes
C. similar habitat
D. similar body size

Answers

The most important in classifying two groups of bears into the same genus are similar genes. The correct option is B.

What is a genus?

Genus is a taxonomic rank that is used to categorize living and extinct creatures, in terms of biology. Genus is placed below family in the biological categorization hierarchy and above species.

The genus contains similar organisms or animals, that are similar like dogs come into cannis and so the wolves, jackals, and similar animals.

In the case of bears, they will come under the same genus if they have similar genes, if they have similar genes, they have similar traits and characters, which will help in classifying them into a genus.

Similar habitat and similar diets or body size do not matter for classifying in the same genus, because two very different animals can have similar diets or habitats.

Thus, the correct option is B. similar genes.

Which of these is a significant effect of vascular plants?

Answers

One significant effect of vascular plants is that they help in maintaining the ecological balance by preventing desertification. Desertification is the process by which a fertile land area becomes desert. Vascular plants are a group of plants that have lignified tissues for conducting water and minerals in the plant.

C. They help maintain ecological balance by preventing desertification. The seed is protected by The Ovaries.
