Lead is toxic, but do you know why?

Biology

Answer:

Lead is toxic mostly because during biochemical reactions it tries to substitute certain metals. hence while doing this, It disrupts with the proteins that control blood pressure, the production of heme and the formation of sperm. Through reactions that propagate electrical signals in the brain, lead often consumes calcium, which reduces the capacity to think and retrieve information.

Answer:

All the options are correct.

Explanation:

Lead is a p-block chemical element having atomic number 82 that belongs to the group 14 of the periodic table.

Lead is a highly toxic metal. It is a neurotoxin which affects the <u>biological enzymes</u> and damages the kidneys and <u>nervous system</u>, thus causing <u>brain damage and behavioral problems</u>.

It mimics and <u>displaces other metals</u> which act as cofactors in various enzymatic reactions. It also affects the b<u>lood pressure, heme synthesis and causes miscarriage in females and reduces the fertility in males.</u>

What steps do you take to make a good science fair project?
Irina-Kira [14]

   Pick a topic.

   Research.

   Hypothesis.

   Experiment.

   Construct an exhibit for results.

   Write a report.

   Practice presenting.

Pick something you are interested in, something you'd like to think about and know more about

Then do some background research on the topic.

Decide whether you can state a hypothesis related to the topic (that is, a cause and effect statement that you can test), and follow the strict method listed above, or whether you will just observe something.

Design and carry out your research, keeping careful records of everything you do or see and your results or observations.

Construct an exhibit or display to show and explain to others what you hoped to test.

Write a short report that also states the same things as the exhibit or display, and also gives the sources of your background research.

Practice describing your project and results, so you will be ready for visitors to your exhibit at the science fair.

How has science and technology influenced everyday life? <br> Explain
aliya0001 [1]

Science and technology have influenced everyday life for thousands of years. If it hadn't we would still be living in caves and struggling to stay alive. Everything you see around you is a form of technology. Science itself can be considered a form of technology because it has helped us advance as humans and become more able to overcome disease and predators. Most humans today wake up and are subjected to technology's control because we've fed into it so much that it would extremely hard, if not impossible, for us to survive without it.

VladimirAG [237]

Answer:

The answer to your question is: letter C

Explanation:

From the graph, we can conclude that catalase has a low activity at low temperatures. Activity increases a little at 30°C and this process is the highest at 40°C, after this temperature, activity disminishes again.

Options:

A. This option is wrong because the number of bubbles at this temperatures is low, maybe the enzyme is already denatured.

B. This answer is wrong, at 30°C the enzyme shows a low activity.

C. This answer is correct because at this temperature the enzyme produces the higher amount of bubbles.

D. The activity of the enzyme at 0°C was not tested.

Assuming DNA is replicated correctly (so there are no mutations),
gavmur [86]

Answer:

None of the choices would lead to all identical gametes.

Explanation:

Gametes are sex cells produced by sexually reproducing organims via a process of cell division called MEIOSIS. Meiosis is a cell division process which produces four (4) daughter cells (gametes), which are genetically different from the parent cell.

The difference in genetical content is as a result of a process unique to only meiosis called CROSSING-OVER OR RECOMBINATION. This process ensures that the genetic content of the gametes are altered. Hence, since gamete formation is done via meiosis, none of the scenarios in the option will lead to all identical gametes.
