Explanation:

The hydrogen atom in the water bond to the hydrogen atoms in the air create a greater surface tension than most other liquid..

Answer:

C

Explanation:

unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles - a positive charge on the hydrogen pole and a negative charge on the oxygen pole.

Answer:

A hydroelectric dam converts the potential energy stored in a water reservoir behind a dam to mechanical energy—mechanical energy is also known as kinetic energy. As the water flows down through the dam its kinetic energy is used to turn a turbine.

Explanation:

An F1 cross between true breeding brown and white lines is set up. What evidence would best support white fur being dominant to brown -----

The best evidence to show that white fur being dominant is when all the offspring after the cross are white instead of brown

They are therefore expected to produce heterozygous lines.

The evidence that would best support white fur being dominant is when all the lines produced are white despite being heterozygous.

A dominant trait is known to mask the expression of other traits.

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.

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.

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.

population is the best answer

Answer: D

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.

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          .

the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

Answer:

Until the past decade, scientists, research institutions, and government agencies relied solely on a system of self-regulation based on shared ethical principles and generally accepted research practices to ensure integrity in the research process. Among the very basic principles that guide scientists, as well as many other scholars, are those expressed as respect for the integrity of knowledge, collegiality, honesty, objectivity, and openness. These principles are at work in the fundamental elements of the scientific method, such as formulating a hypothesis, designing an experiment to test the hypothesis, and collecting and interpreting data. In addition, more particular principles characteristic of specific scientific disciplines influence the methods of observation; the acquisition, storage, management, and sharing of data; the communication of scientific knowledge and information; and the training of younger scientists.1 How these principles are applied varies considerably among the several scientific disciplines, different research organizations, and individual investigators.

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!

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.
