Describe one possible effect of a gene mutation in a body cell on an organism and one possible effect on the offspring of that organism

A gene mutation may result in an oncogene. So during that cell's replication the gate keeper genes will no longer be able to suppress it. This results in a mutated daughter cell.  If there is a subsequent mutation an a daughter cell, a tumor will be produced. 

Gene mutation can also cause mosaicism and result in different phenotypes

A child has sickle-cell disease (ss) but neither parent is ill. what must be true of her parents’ genotypes?

Answer;

-Both parents are carriers of the sickle cell genes, they have one sickle cell gene and thus they do not show the trait.

Explanation;

-Sickle Cell Anemia is an autosomal recessive trait. This means that in order for the trait to be shown, both parents of an individual must carry at least one sickle cell gene.

- A child with this disorder can be born to parents who do not have the disorder because the parents must have at least one gene, but do not have two and therefore do not show the trait. Since it is recessive, in order to show the trait, you must have two of the genes.

Materials are able to move across a cell membrane through one of two methods: active transport or passive transport. What is the difference between active transport and passive transport?

Essentially the answer is in the names. Active transport requires energy to facilitate to movement of the materials while passive transport is something like osmosis which is when the material moves based on concentration in an effort to create equality between the two sides. Basically passive is when the materials move under the own power.

QUESTION POSTED AT 22/02/2020 - 04:27 PM

If you were stranded on the ocean in a raft, what would happen if you kept drinking ocean water? your blood would become hypotonic your blood would become hypertonic the concentration of water in your blood would increase the concentration of water in your blood would decrease water would flow out of your body cells the excess water would flow into your cells

The correct answer is that water will flow out of the cells of the body.  

When one consumes salt water, the concentration of solutes external to the cells will enhance making the water inside the cell to move out of the cells, thus, making the cells shrink. Outside the cell, the solution is hypertonic and may result in dehydration.  

The kidneys in human can only produce urine, which is less salty in comparison to salt water. Thus, to withdraw all the extra salt consumed, one has to urinate more water than one has drunk. Hence, resulting in dehydration.

Which is a tough and flexible layer that surrounds plant cells, as well as some algal and bacterial cells? cell wall centriole nucleus cell membrane

Answer: Cell wall is the layer which is present in plant cells, as well as some algal and bacterial cells.

Cell wall is the outermost layer of the cell which surrounds plasma membrane. It provides structural support and protection to the cell. It is absent in animals.

In plant cells, cell wall is mainly made up of cellulose. In bacterial cells, it is made up of peptidoglycan, whereas in algal cells, the major components are chitin, glucan and protein.

Explain the genetic events that enable so many different cell types to arise from one unspecialized cell

All cells in the body have the same genetic material, e.g. they have same DNA. However, not all genes are active at the same time and in all cells. Thus, different genes are transcribed in different specialised cells. There are transcription factors that control which genes will be transcribed and which will be suppressed. Also, specialised cells in an embryo release signalling proteins that help in cell differentiation.

Substances that enter the cell without the expense of cellular ATP, but are too large to directly pass through the membrane, use ________________________ in order to gain access to the inside of the cell. A) vesicles B) osmosis C) pseudopodia D) membrane proteins

Answer: Membrane proteins

Explanation:

Membrane proteins are common type of proteins that are the part of membrane or interact with membranes.

It falls into many criteria based on the  location the membrane proteins are found. It can be found on the either sides of the membrane. inside the cell or outside the cell.

It acts as the receptors for specific molecules or it can also help in the transportation of the molecules across membranes. The molecules that are too large to be transported across membrane enters with the help of cell membrane.
