B. They express the recessive trait
The carriers for a disease in a pedigree analysis is a heterozygous. They contain a dominant and a recessive allele. Thus, correct options are A, C and D.
What are genes?A gene is a segment of DNA that contains all the information for the development of organism. A carrier in genetics, is an individual who “carries” and can pass on to its offspring an allele associated with a disease and does not show symptoms of that disease. A carrier is an organism that carries two different alleles of a recessive gene and is thus heterozygous for that the recessive gene.
Dominant genetic disorders are those in which a mutation in just one copy of the gene pair is required for the disorder to develop. However, in recessive genetic disorders both alleles need to be recessive for the gene. This disease symptoms are only observed in case of homozygous condition.
Therefore, the correct options are A, C and D.

When referring to cell division, oncogenes are most like ________ while tumor suppressor genes are most like ________. the brakes on a car; the gas pedal on a car the steering wheel on a car; the gas pedal on a car the gas pedal on a car; the brakes on a car the brakes on a car; the steering wheel on a car
Oncogenes are most like the gas pedal on a car, while tumor suppressor genes are most like the brakes on a car. Oncogenes and tumor suppressor genes are mutated in cancer cells.
Oncogenes are genes overexpressed in cells in which they should not be expressed, thereby leading to cancer.
Some examples of oncogenes are growth factors such as, for example, the Platelet-derived growth factor (PDGF) or Epidermal growth factor (EGF).
Conversely, tumor suppressor genes are genes that act to regulate cell division and replication, thereby their inactivation also leads to cancer.
A well-known example of a tumor suppressor gene is the p53 gene that acts to control cell division and apoptosis (programmed cell death).

Wjy is the increase in atmospheric carbon dioxide dangerous?
Answer:
The gas inhibits the escape of heat from Earth’s
Explanation:
This is the main cause of global warming. They cause climate change by trapping heat and they also contribute to respiratory disease from smog and air pollution. Extreme weather, food supply disruptions, and increased wildfires are other effects of climate change caused by greenhouse gases.
The earth temperature depends upon the balance between the incoming radiation from the sunlight and the energy that is reflected back to space. Carbon dioxide absorbs the heat sent to earth by the sun, it acts as an insulator of the earth and helps to keep the atmosphere warm and make suitable for life process.
But, when the concentration of carbon dioxide in the atmosphere is increased, it means more and more increase in the temperature of the planet and cause global warming and make the life difficult on the planet. As a result of that whole life on the earth would be in danger.
Answer:
If you increase carbon dioxide, the temperature can go up causing our earth to have global warming problems.

what will happen to a population of organisms that are in an environment with little to no oxygen?
Answer:
Hypoxia occurs when algae and other organisms die from lack of oxygen and available nutrients. Hypoxia events often follow algal blooms. The cyanobacteria, algae, and phytoplankton sink to the seafloor, and are decomposed by bacteria. This lack of oxygen creates dead zones in which most aquatic species cannot survive.

Explanation:
How might photosynthesis account for seasonal changes in carbon dioxide in the atmosphere? ( for example, why might carbon dioxide levels be highest in May but lowest in October? )
Answer:
When plants are growing, photosynthesis outweighs respiration. As a result, plants take more CO2 out of the atmosphere during the warm months when they are growing the most. Levels of carbon dioxide in the atmosphere rise and fall each year as plants, through photosynthesis and respiration, take up the gas in spring and summer, and release it in fall and winter. Now the range of that cycle is expanding as more carbon dioxide is emitted from burning fossil fuels and other human activities.

Pick one sentence or paragraph from the article, and explain how it supports the idea that science is an evolving discipline that depends on repeated testing.
Answer:
From Edmentum:
“Paleontologists used to think that dinosaurs were similar across the continents—at least during the Jurassic period, says Novas. C. diegosuarezi’s mix of features now brings a wrinkle of doubt to that idea.” The paragraph explains that this new dinosaur gives some evidence that the dinosaurs in South America were structurally different from dinosaurs in other areas of the world. According to the paragraph, scientists will need to find and examine more dinosaur fossils from this region before they can support this claim. The claim supports the statement that science requires repeated testing.
Reworded:
“Paleontologists used to think that dinosaurs were similar across the continents—at least during the Jurassic period, says Novas. C. diegosuarezi’s mix of features now brings a wrinkle of doubt to that idea.” Paleontologists used to think all dinosaurs were similar all around the world, but the structure of a specific species of dinosaur made them second guess themselves. It seemed that the dinosaurs in South America were evolving different structures and functions than dinosaurs from other continents. The claim supports that the statement needs more testing.
Explanation:
Answer:According to Novas, "Paleontologists once believed that dinosaurs were identical on all continents, at least during the Jurassic era. The combination of traits on C. diegosuarezi currently casts some doubt on that theory. The structure of a particular species of dinosaur caused paleontologists to reevaluate their previous belief that all dinosaurs were globally identical. It appeared that the architecture and functions of South American dinosaurs were evolving differently from those of dinosaurs from other continents. The claim argues in favor of additional testing for the assertion.

what would happen to you metabolically if all your mitochondria were destroyed
Answer:
You would die
Explanation:
if you lost your mitochondria you would die
The loss of functional mitochondria would result in a severe energy crisis within the cell, affecting ATP production and impairing Fatty acid metabolism and calcium homeostasis.
Mitochondria are known as the "powerhouses" of the cell because they are responsible for producing most of the cell's adenosine triphosphate (ATP).
The following processes would be affected:
1. ATP production: Without functional mitochondria, ATP production would be significantly reduced, leading to a severe energy deficit within the cell.
2. Oxidative phosphorylation: Mitochondria are crucial for oxidative phosphorylation, a process that occurs in the inner mitochondrial membrane and generates a large amount of ATP. Without intact mitochondria, oxidative phosphorylation would be disrupted, impairing ATP synthesis.
3. Metabolism of fatty acids: Mitochondria are involved in the breakdown of fatty acids through a process called beta-oxidation. If mitochondria were destroyed, the ability to efficiently metabolize fatty acids would be compromised.
4. Reactive oxygen species (ROS) regulation: If mitochondria were destroyed, the regulation of ROS levels would be impaired, potentially leading to oxidative damage and disruption of cellular processes.
5. Calcium homeostasis: Mitochondria are involved in maintaining calcium homeostasis within cells. Loss of functional mitochondria would disrupt calcium regulation, which could affect various cellular functions, including muscle contraction, enzyme activity, and cell signaling.
Therefore, the loss of functional mitochondria would result in a severe energy crisis within the cell, affecting ATP production and impairing various metabolic processes.

which molecules determine the tissue specificity of hormones?
Answer:
Steroids. Which molecules determine the tissue specificity of hormones? Receptors. Hormones bind to receptors on target cells and trigger a cellular response.
Explanation:
The tissue specificity of hormones is determined by hormone receptors. Proteins called hormone receptors are found on the cell surface. A hormone's binding to its receptor starts a chain of actions that eventually affects the activity of the cell.
For various hormones, different cells have various receptors. This implies that a hormone can only attach to cells that also contain such receptors. The tissue specificity of hormones is a result of this.
For instance, the insulin hormone attaches to receptors on cells in the muscle, fat, and liver tissues. These receptors bind to insulin, which sets off a series of processes that eventually result in the absorption of glucose from the circulation by these cells.
