What is cell cycle?
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.

what causes genetic variation in meiosis?
A. chromosomes lining up
B. separation of chromosomes
C. crossing over chromosomes
D. chromosomes pulling apart
Answer:
C. crossing over chromosomes
Explanation:
Process of Meiosis. A man produces sperm and a woman produces eggs because their reproductive cells undergo meiosis.which cause Crossing Over.
A female mouse is trying to decide if she will leave her natal nest to reproduce alone. If she leaves, she will be able to produce 45 offspring whereas she would only have 7 reproductive units if she stayed. But if she stays, she will help her mother produce 175 offspring vs the 85 she could produce without her. Should she stay
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.
What is reproduction?
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.

as a microbiologist you have been asked to investigate the regulation of a novel gene in a bacterial species. given what is known about bacteria, the logical place to begin your investigation is
The logical place to begin your investigation is TRANSCRIPTIONAL CONTROL. This field investigates the differential expression of genes.
Transcriptional control refers to the study of how genes are differentially expressed in the genome of cells.
In prokaryotic organisms (e.g., bacteria), genes are expressed in clusters known as operons.
An operon is a group of genes under the control of a single promoter sequence.

Blood vessel diameter fluctuates between being constricted and being dilated. This is the primary contributor to blood pressure. In order for blood vessels (arterioles) to maintain a steady pressure, there must be a prolonged presence of what ion in the smooth muscle cell's cytosol
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.

what are the similarities between this activity and actual mitosis
The DNA within a cell is duplicated during both meiosis and mitosis. Two sister chromatids are produced for each chromosome as a result of the replication and continued joining of each DNA strand, or chromosome.
What is mitosis?Mitosis is defined as the cell-division process in which the chromosomes multiply and are equally distributed between the two daughter cells. Prophase, Prometaphase, Metaphase, Anaphase, and Telophase are the five stages that make up mitosis. Meiosis is defined as a process by which a single cell undergoes two divisions, resulting in four cells with half the original genetic material.
Cell division occurs during meiosis as well as mitosis. The M-phase of the cell cycle is where both processes take place. The prophase, metaphase, anaphase, and telophase stages are typical for both cycles. DNA synthesis occurs during both cycles. A common goal of meiosis and mitosis is the division of the nucleus and its DNA into two daughter cells.
Thus, the DNA within a cell is duplicated during both meiosis and mitosis. Two sister chromatids are produced for each chromosome as a result of the replication and continued joining of each DNA strand, or chromosome.

In the general population, 1 in 300 individuals is a carrier for Tay-Sachs disease, while 1 in 30 individuals of Ashkenazi Jew descent are carriers. Tay-Sachs also affects 1 in 30 individuals with French-Canadian ancestry, although two completely unique mutations are responsible for the Ashkenazi and French-Canadian mutations.
A) What are the chances of two individuals having a child with Tay-Sachs if both individuals are not of Ashkenazi or Franch-Canadian descent?
B) What are the chances of two Individuals having a ¢hild with Tay-Sachs lf one Individual Is of Ashkenazi descent and one ls not?
In the general population where 1 in 300 individuals is a carrier for Tay-Sachs disease, while 1 in 30 individuals of Ashkenazi Jew descent are carriers. Tay-Sachs also affects 1 in 30 individuals with French-Canadian ancestry then in this condition , 1 in 2 will get the disease that is there is 50% possibility.
What type of disease is discussed in the question ?It is an autosomal recessive disorder.
The chances where the two two individuals having a child with Tay-Sachs if both individuals are not of Ashkenazi or Franch-Canadian descent is 25 % that is the child will not have any disease.
The chance where the child inherits a mutated one from one parent and becomes a carrier, but will not have the condition themselves. 1 in 4 (25%) chance that means the child inherits a faulty gene from both parents and develops Tay-Sachs disease.
