Answer: db a
Explanation:
Answer:
This is for the offspring to show traits that come from both the mother and father.
Explanation:
Gametes are formed by a kind of cell division called meiosis in which the chromosome number is halved. Thus the said gamete cell is said to contain a haploid number of chromosomes.
The fusion of two haploid gametes is called fertilization. It results in the formation of single celled zygote which has a diploid number of chromosomes. The zygote now divides and develops to produce the offsprings whose somatic cells are diploid.
Answer:
When this reaction takes place, water dissolves ions from the mineral and carries them away. These elements have undergone leaching. Through hydrolysis, a mineral such as potassium feldspar is leached of potassium and changed into a clay mineral.

Which statement is most supportive of the claim that genetic diversity is an advantage of sexual reproduction?
Genetic variation from sexual reproduction ensures that at least some individuals will have advantageous traits that help them survive.
Asexual reproduction results in the same genes being copied, which means the same vulnerabilities in the population.*******
Sexual reproduction creates genetic diversity, which results in a wide range of appearances in a population.
Lack of genetic diversity from asexual reproduction results in a diminished ability to survive changes to the environment.
What is the most likely explanation for a child exhibiting a heritable trait that neither parent exhibits?
The trait was passed on by a different biological parent, and one of the child's parents is not biologically related.
The trait was inherited from a more distant relative, like a great-grandparent.
The parents carried a second trait that masked the trait of interest.
The trait is recessive, so both parents carry it, and the child inherited each recessive allele.**********
Which statement has exceptions?
Sexual reproduction requires two parents, whereas asexual reproduction requires only one parent.
Sexual reproduction produces genetic variation, but asexual reproduction does not.
Sexual reproduction is more complex, while asexual reproduction is a simpler process.
Sexual reproduction involves parental care, while asexual reproduction does not.******

Hydras are animals related to coral and jellyfish. Hydras can reproduce sexually or asexually. Why would hydras avoid reproducing asexually when conditions are difficult?
The lack of genetic diversity could mean that all of the hydras die, depending on the situation. ******
The high genetic diversity could mean that all of the hydras die, depending on the situation.
Reproducing more rapidly would be a good way to take advantage of plentiful resources.
Reproducing more slowly would be a good way to take advantage of plentiful resources.
Sexual reproduction creates genetic diversity, allowing some individuals to have advantageous traits. Inheriting a trait that neither parent exhibits suggests it is recessive and both parents carry it. Hydras avoid asexual reproduction when conditions are difficult to prevent a lack of genetic diversity.
The statement that is most supportive of the claim that genetic diversity is an advantage of sexual reproduction is: Genetic variation from sexual reproduction ensures that at least some individuals will have advantageous traits that help them survive. Sexual reproduction creates unique combinations of genetic material through the process of fertilization, resulting in offspring with diverse traits. This genetic diversity increases the likelihood of individuals having advantageous traits that can help them adapt and survive in changing environments.
In the case of a child exhibiting a heritable trait that neither parent exhibits, the most likely explanation is that the trait is recessive and both parents carry it. This means that the child inherited two copies of the recessive allele, one from each parent, which is necessary for the trait to be expressed.
Hydras, despite being capable of reproducing asexually, would avoid doing so when conditions are difficult because asexual reproduction does not create genetic diversity. Without genetic diversity, all hydras in the population would have the same traits, making them vulnerable to changes in the environment.

The absorption of triglycerides is not a function of stomach. Option D is correct.
The stomach performs various functions in the digestive system which includes,
The absorption of triglycerides is performed by the small and large intestine after breakdown.
Therefore, the absorption of triglycerides is not a function of stomach.
To know more about absorption of triglycerides,
Answer:
absorption of triglycerides.
Explanation:
The stomach is a digestive organ present in the digestive system which is characterized by the J-shape.
The stomach performs various functions in the digestive system which are very important for digestion of food.
The stomach is involved in churning or breaking down larger pieces into smaller pieces, initiation of protein digestion as it secretes trypsin and chymotrypsin where this enzyme denatures the protein structure present in food and storage of food. But the function of absorption of triglycerides is performed by the small and large intestine which can absorb the triglyceride.
Thus, the selected option is the correct answer.
The correct answer is the option (A) heparin.
DVT refers to a condition called the deep vein thrombosis when a blood clot occurs in the deep veins of the legs in the body. PE refers to the Pulmonary embolism when a blood clot is observed in the artery of the lungs.
The drugs used in the treatment of DVT and PE are called the anticogulants which interfere with the process of blood clot formation. Heparin and warfarin are the two older anticoagulants used in the prevention and treatment and prevention of DVT and PE. Heparin is given intravenously to treat DVT and PE whereas, warfarin is taken as a tablet or pill through the mouth. Heparin allows the body's clot lysis mechanism to break down the existing clots and it is also a natural anticoagulant produced by the basophils and the mast cells of the blood.
Thus, heparin is the old drug that is used subcutaneously to prevent DVT in high-risk patients and intravenously to treat DVT and PE.
