Explanation: Sieves are used to separate the solid smaller particles from a mixture. They are usually made of metal or fine plastic mesh, with openings between the wires that are sized according to the sizes of the desired particles in the mixture. Dried foods such as beans and rice are separated by using screens with openings of different sizes, small for whole grains, larger for cracked grains. Other kinds of products which require separation may be filtered through sieves, including sugar mixtures before they are packed or bottled.

Answer:  XHY

Explanation:

The hemophilia disease will be present in the progeny if they solely carry the Xh allele/alleles and lack the XH gene, the genotype of man is XhY.

Haemophilia was once thought of as an example of Mendelian inheritance since the disease phenotype is caused by a mutation in just one gene (F8 or F9).

But research has shown that the illness has strong genetic and phenotypic heterogeneities. The gene for either the factor VIII protein or the factor IX protein has a mutation (different from normal) in hemophilia patients.

The mutation makes the body manufacture insufficient amounts of factor VIII or factor IX.

Therefore, A normal phenotype will result from having one XH allele because this condition is recessive, the genotype of a man is XhY.

Answer:

A movement of a body part away from the midline, either of the body as a whole or that of the hand or foot, is termed abduction (L., to carry away). A movement of the body part back toward the midline (i.e., to the anatomical position) is known as adduction.

Explanation:

Mark me brainly please.

Abduction is a movement away from the body's midline. Abduction is the term for a bodily part's lateral movement away from the body's midline.

Thus, body parts are divided or spread apart in this process. Abduction of the arms, for instance, occurs when you raise your arms from a resting posture and spread them out to the sides. Similar to this, you are practicing leg abduction when you stretch your legs apart.

Adduction, or the movement in the direction of the midline, is the reverse of this action. Important terminology like abduction and adduction are used to describe movement in respect to the body's midline in anatomical and physiological descriptions.

Answers:

High-energy electrons from NADH and FADH2, are passed into and along the   electron transport chain   .

The energy from the electrons moving down the chain is used to move H+ ions across the   inner membrane   .

H+ ions build up in the    intermembrane     space, making it    positively     charged and making the matrix negatively charged.

In the inner membrane, H+ ions move through channels of   ATP synthase   .

The ATP synthase uses the energy from the moving ions to combine ADP and phosphate, forming high-energy         ATP          .

c. The skull is hard which protects the brain from being injured

Explanation:

Answer:

The one that makes sense is C.) "The skull is hard which protects the brain from being injured." here's why:

Explanation:

The skull performs vital functions. Mainly, it supports and protects the head's soft tissues. The baby's skull is soft but as the bones developed, the bones of the skull form a tough, fibrous membrane and slowly fuse to form a single skull. The mandible is the only bone that separates from other parts of the skull. The skull or known as the cranium in the medical world is a bone structure of the head. It supports and protects the face and the brain. The adult skull has a total of 22 individual bones. They don’t move and united into a single unit. The skull performs vital functions. Mainly, it supports and protects the head’s soft tissues. The baby's skull is soft but as the bones developed, the bones of the skull form a tough, fibrous membrane and slowly fuse to form a single skull. The mandible is the only bone that separates from other parts of the skull. So, as our cranium grow it gets tough enough to protect the brain from injury!

Given what we know about the behavior of gases like helium, we can confirm that the small tank of helium was able to fill so many balloons because the helium expanded to fill its new container, which is the balloon.

Helium is a chemical element known as a noble gas. Like all other elements in a gaseous state, the atoms that comprise helium are spaced apart. This allows the gas to be compressed, a property that manufacturers of the gas take advantage of since they can compress a large amount of gas into a small container.

This is precisely what is happening in the question. The small tank of helium, despite being small in size, contains a large amount of compressed helium gas. Therefore, once it is released from the container, the gas expands to fill its new container, which in this case is the balloons, because of this, a relatively small tank of helium was able to fill many large balloons.

They reproduce quickly and take up little space.

Fruit flies (Drosophila melanogaster) are advantageous in the study of human inheritance because they have several characteristics that make them well-suited for genetic research. One key advantage is their rapid reproductive cycle, with a generation time of about two weeks. This allows researchers to observe multiple generations in a short period, accelerating the study of inheritance patterns and genetic traits.

Additionally, fruit flies have a relatively small size, making it feasible to maintain large populations in a laboratory setting without requiring excessive space or resources. This allows for efficient experimental design and the ability to conduct large-scale genetic studies.

While fruit flies share some genetic similarities with humans, they are not identical to humans. However, their genetic and developmental processes have enough similarities to provide valuable insights into fundamental principles of inheritance and gene function, which can inform our understanding of human genetics.

Answer: Single-stranded; complementary base pairing

Explanation:

Restriction enzymes are essential components of recombinant DNA technology because they can be extracted from bacterial cells and utilized in the lab to modify DNA fragments, including those that contain genes (genetic engineering).

An isolated bacterial protein called a restriction enzyme breaks DNA at specific sequence-specific locations to produce DNA fragments with a known sequence at each end.

For several laboratory techniques, such as genetic engineering and recombinant DNA technologies, restriction enzymes are essential.

Therefore, In creating recombinant DNA, some restriction enzymes produce Single-stranded  ends in both the source DNA and plasmid DNA, and these ends can stick to each other by complementary base pairing.
