Ksju [112]3 years ago

Answer:

If both parents do not have sickle-cell anemia, than the possibility is low.

Explanation:

If both parents have the sickle-cell trait, their offspring has a 25 percent chance of getting sickle cell anemia and a 50 percent risk of them having sickle cell trait. Meanwhile, there is also a 25 percent chance of the child not getting it at all.

If one parent has sickle cell anemia and the other has sickle cell trait, then their offspring with have a 50 percent chance of getting sickle cell anemia and a 50 percent chance of getting a sickle cell trait.

When both parents have sickle cell anemia, their child will definitely have it.

Answer:

No, 0% chance

Explanation:

none of the parents are carriers of this disease, and are homozygous dominant to the normal red blood cells, so they will not inherit this disease

How do biozones help scientists? Choose all that apply. A) The relative age of the rock can be determined by the types of fossil
podryga [215]

Answer:  C). A biozone can help trace the path of evolution over time.

Biozone is a stratigraphic unit which contains fossils in layers of strata existed in a particular geologic period.  It is named as biozone because it depicts the number of biological taxa existed in particular strata. Therefore, the variation in features within taxonomic groups in biozones can give indication of evolution with respect to time.

Dina is a paleoclimatologist. she wants to review documents to assess climate data for her hometown. which historical documents
lana66690 [7]

Newspaper articles and farmers harvest yield record are the documents should Dina examine in order to assess this climate data.

Among atmospheric scientists is a group known as paleoclimatologists. There were 11,800 workers in this field in 2014, albeit not all of them were climatologists or paleoclimatologists, according to BLS data. With 40% of the workforce, professional, scientific, and technical services was the main employer of atmospheric scientists.

<h3>What level of education is required to work as a paleoclimatologist?</h3>

Your future work as a paleoclimatologist will involve a lot of biology, physics, and other hard sciences, thus there are lots of degree programs that mix these fields with the environment. Environmental biology and environmental chemistry are two examples of such options.

<h3>How far into the past can paleoclimatology take us?</h3>

Paleoclimatology makes extensive use of polar ice sheets and ice caps as well as mountain glaciers. Data from ice-coring efforts in the ice caps of Greenland and Antarctica date back over 800,000 years in the case of the EPICA project, or several hundred thousand years.

<h3>Why is paleoclimatology essential and what does it entail?</h3>

Our knowledge of Earth's climate depends on the science of paleoclimatology. Scientists can create models to help predict how rising carbon dioxide levels and other changes can affect the climate of Earth in the future as they become more aware of how climates have been influenced in the past.

Energy Metabolism Pathways Carbohydrate metabolism is responsible for the formation, breakdown, and interconversion of carbohydr
Ksivusya [100]

Answer:

The glucose conversion to PYRUVATE opens anaerobic and aerobic metabolic pathways. VITAMIN B NIACIN in its role as a coenzyme during glycolysis, escorts hydrogen and electrons to the electron transport chain and the TCA cycle. In the Cori cycle, the release of energy from ATP converts lactate to glucose and returns the glucose molecule to the muscles through the process of Anaerobic Glycolysis.

Explanation:

In metabolism, glycolysis is defined as the splitting of the glucose molecule to form two molecules of pyruvic acid. It is the first main metabolic pathway in cellular respiration for the production of energy in form of ATP(Adenosine triphosphate).

In most cells, cellular respiration occurs in the presence of oxygen. This is known as AEROBIC RESPIRATION which produces the largest number of ATP. Energy can also be gotten by breaking down of glucose in the complete absence of oxygen. This is known as ANAEROBIC RESPIRATION.

The next stage in the degradation of glucose is a two step conversion of the two pyruvic acid molecules from glycolysis into two molecules of acetyl coenzyme A( acetyl - CoA). This occurs in the TCA( tricarboxylic acid) or Krebs cycle.

VITAMIN B NIACIN in its role as a coenzyme during glycolysis, escorts hydrogen and electrons to the electron transport chain and the TCA cycle. Coenzyme A is a derivative of vitamin B which combines with pyruvic acid to form acetyl CoA , 2 molecules of carbon dioxide and 4 molecules of hydrogen in TCA cycle.

In Cori Cycle, (which is also called Lactic acid cycle), energy released from ATP is used to convert lactate to glucose. This is to prevent increased lactic acid in the blood during anaerobic conditions in the muscles.

Explain the effects of osmosis on cells and tissues:
viva [34]

Answer:

In explanation.

Explanation:

Effect of osmosis on cells:

-Osmosis is the movement of water across a cell membrane. Cells use osmosis to maintain concentration equilibrium (the concentrations of solute inside and outside the cell are equal). Changing the amount of water allows the cells to achieve equilibrium.

Effects of osmosis on tissues:

-Red blood cells placed in a solution with a higher water concentration compared to their contents (eg pure water) will gain water by osmosis, swell up, and burst. Water will diffuse from a higher water concentration outside the cell to a lower water concentration inside the cell.

Hope this helps.
