to inherit an autosomal dominant disorder a person could receive the allele leading to the disease from

Answers

To inherit an autosomal dominant disorder, a person could receive the allele leading to the disease from either of their parent, that are expressed as dominant one copy in the individual's genome.

In general , Autosomal dominant disorders are result of dominant allele that are located on one of the autosomes of  genome. Hence, they only need one copy of the disease causing allele . This is in contrast to recessive disorders, which require two copies of the disease-causing allele for the individual to express the disorder.

Hence, It is important to mention  that individuals those who are inheriting the dominant allele but do not express the disorder can be the carriers and can potentially pass the allele on to their offspring.

In which would you be most likely to find plants and animals that are adapted to survive in extremely cold temperatures

Answers

This question is incomplete because part of the content is missing; here is the   complete question:

In which biome would you be most likely to find plants and animals that are

adapted to survive in extremely cold temperatures?

A. Desert

B. Savanna

C. Rain forest

D. Tundra

The correct answer is D. Tundra

Explanation:

Tundra biome is one of the coldest biomes on Earth, indeed, the temperature in this biome can be as low -50° C in some zone. At this extremely cold temperature, animals and plants have adaptations to survive in these climatic conditions. For example, animals such as the arctic hare or the polar bear that are found mainly in the tundra biome have thick fur that helps them keep body temperature despite low temperatures in their environment. Thus, the biome in which you would most likely find species adapted to extremely cold temperatures is the Tundra.

Which unexpected unexpected state are there fossils of tropical plants?​

Answers

Finding fossils of tropical plants is not typical in tropical environments, as they are associated with warm and humid conditions, while fossils are usually found in regions with more temperate climates.

What is the significance of the fossils in different climates?

Fossils are usually found in regions with more temperate climates, but the fossils of tropical plants were discovered in Antarctica because, during the Early Cretaceous period, Antarctica was much warmer and had a more temperate climate.

Hence, finding fossils of tropical plants is not typical in tropical environments, as they are associated with warm and humid conditions, while fossils are usually found in regions with more temperate climates.

Explain what the acoustic measure H1-A3 is. Additionally discuss why a large value of the measure H1-A3 would reflect a breathy voice. (Hint: consider using these terms: vocal fold closure, spectral tilt).

Answers

The acoustic measure H1-A3 represents the difference in frequency between the first harmonic (H1) and the third formant (A3) in a speech signal.

The first harmonic is the lowest frequency component of the voice signal, while the third formant is a resonance frequency that is related to the shape and size of the vocal tract.

A large value of H1-A3 indicates that the third formant is higher in frequency than the first harmonic, which is a characteristic of breathy voice quality.

This is because breathy phonation is associated with incomplete vocal fold closure, which results in a weaker and more turbulent airflow through the vocal tract.

This causes a change in the spectral tilt, which in turn leads to an increase in the frequency of the third formant relative to the first harmonic, resulting in a larger H1-A3 value.

Answer:

Explanation: the answer is 69 chromosomes

If a normal cell has 46 chromosomes, then the new cell will also have 46 chromosomes after mitosis. Hence, option C is correct.

What is mitosis?

When a parent cell divides to create two identical daughter cells, the process of the nuclear division known as mitosis takes place in eukaryotic cells. Mitosis refers particularly to the division of the duplicated genetic material contained in the nucleus during cell division.

Mitosis is a process used to create more cells that share the same genetic makeup as the parent cell. It is crucial for the growth and development of human bodies as well as for the embryonic development of living things. Mitosis generates new cells and replaces injured, destroyed, or aging ones.

The new daughter cell has the same amount of chromosomes as the parent cell. Hence, option C is correct.

If the DNA sequence is CCAATTGA, what is the compliment?

Answers

GGTTAACT is the complement of DNA sequence CCAATTGA.

What is a complement sequence of DNA?

A sequence of bases in a nucleic acid called a complementary sequence can be used to match base pairs to create a double-stranded structure. For instance, G-T-A-C is the complementary sequence to C-A-T-G, where each letter represents a different DNA nucleotide.

Every DNA sequence has a counterpart sequence running in parallel since DNA has two strands. Adenine (A) is always coupled with Thymine (T) in the complementary sequence, while Cytosine (C) is always paired with Guanine (G).

Natural complementary DNA plays a crucial role in the production of new DNA copies and has emerged as a key experimental tool. The two strands of DNA are unraveled from one another during replication. Each strand is replicated twice, one by a DNA polymerase molecule that runs the length of each strand.

3. How is Acetyl-CoA prsluced during the acrobic oxidation of carbohydrates, and what happens to it? How is it produced during the aerobic oxidation of titty acids, and what happens to it

Answers

During the aerobic oxidation of carbohydrates, acetyl-CoA is produced through a series of metabolic reactions known as glycolysis and the citric acid cycle. During the aerobic oxidation of fatty acids, acetyl-CoA is produced through a process called beta-oxidation.

Pyruvate then enters the mitochondria, where it undergoes further processing to produce acetyl-CoA. This conversion occurs through a process called pyruvate decarboxylation, where pyruvate loses a carbon dioxide molecule and combines with coenzyme A (CoA) to form acetyl-CoA. Acetyl-CoA is a key molecule in energy metabolism and serves as a precursor for the citric acid cycle.

During the aerobic oxidation of fatty acids, acetyl-CoA is produced through a process called beta-oxidation. Fatty acids are broken down into two-carbon units, which then combine with CoA to form acetyl-CoA. This process occurs in the mitochondria, where fatty acids are sequentially cleaved into acetyl-CoA molecules. The acetyl-CoA molecules can enter the citric acid cycle to generate energy through oxidative phosphorylation.

Once acetyl-CoA is produced, it enters the citric acid cycle, also known as the Krebs cycle or TCA cycle. In this cycle, acetyl-CoA undergoes a series of enzymatic reactions, resulting in the production of ATP, NADH, and FADH2. These energy-rich molecules are then utilized in the electron transport chain to generate ATP through oxidative phosphorylation.
