Cell cycle is defined as cycle in which cell produces, grows and divides. The cell cycle has mainly three steps the first one is G1 phase in which the size of cell increases, S phase synthesis of DNA takes place and the third step is G2 phase in which cell ready to divide.

Cell is defined as the base of life as it is the structural as well as functional unit of life. Cell is made up of pre existing cells and the cell contain various cell organelles such as mitochondria, endoplasmic reticulum, ribosomes, golgi appratus, nucleus, and cytoplasm.

Basically, cell is of two type one in prokaryotic and another one is eukaryotic. The prokaryotic cell is known as pre mature cells as they do not contain cell organelles and eukaryotic cell are known as advanced and developed cells as they contain several cell organelles.

Therefore, Robert Hooke was the first person to observe cells. He observed these cells in a piece of cork. Thus, option A is correct.

Answer:

142 is the answer whe you add 45 7 and 85

A female mouse is trying to decide if she will leave her natal nest to reproduce alone. She will produce 142 offspring.

Reproduction is the production of offspring. There are two main forms: sexual and asexual reproduction. In sexual reproduction, an organism combines the genetic information from each of its parents and is genetically unique.

In asexual reproduction, one parent copies itself to form a genetically identical offspring. Sea turtles are an example of an animal that reproduces sexually, a volvox (green algae) is an example of an organism that reproduces asexually, and a brittle star can reproduce in either way.

Reproduction is the process by which new organisms (offsprings) are produced from organisms of the same kind.

Therefore, A female mouse is trying to decide if she will leave her natal nest to reproduce alone. She will produce 142 offspring.

Explanation:

In order for blood vessels to maintain a steady pressure, there must be a prolonged presence of CALCIUM ions in the smooth muscle cell's cytosol. This ion initiates smooth muscle contraction.

Arterioles are blood vessels that have muscular walls consisting of one or two layers of smooth muscle cells.

Calcium (Ca2+) ions start the contraction of the smooth muscle cells by binding to calmodulin protein and thereby activating myosin.

In consequence, Ca2+ ions act as a secondary messenger that activates calmodulin, stimulating the phosphorylation of the myosin light chain and thus triggering muscle contraction.

In the modern system of biological classification the genus and species names are used for the scientific name of organisms.

The modern system of biological classification is the classification that involves the naming and arrangement of organisms in groups according to a hierarchical order.

In this type of classification, organisms are given scientific names based on their genus and the species.

This pattern of double naming is called binomial nomenclature consisting of two names.

Therefore, in the modern system of biological classification the genus and species names are used for the scientific name of organisms.
