Carbon dioxide is formed when two oxygen atoms chemically combine with a carbon atom which term best describes carbon dioxide?
A Mixture
B atoms
C elements
D compound

Answer:

The correct options are B "The unusual F1 female is heterozygous for a reciprocal balanced translocation involving the chromosome with the apricot, bristle and clipped loci" and D "Independent assortment of non-compatible chromosome structures (i.e., translocated and normal chromosomes segregating together) in the F1 female led to the 90 eggs that aborted development"

Explanation:

The unexpected results obtained earlier can be attributed to the two factors listed above. At the time when meisois takes place, there is the process of independent assortment which leads to formation of zygotes. Due to the event of translocation, the eggs produced lacked some critical development genes.

One allows microbe to move in the medium and the other allows to see it.

Explanation:

Both microscopy and motility agar are required to determine motility in some microbes because both substances helps to find out the mobility in the microbes. Motility agar is the medium that allows microbes to swim if they have flagella in their body while on the other hand, microscope is used to see the movement of microbes in motility agar. Microbes are small creature which can't be seen through naked eyes so we used microscope for it.

Explanation:

Inhibition of electron flow inhibits mitochondrial ATP synthesis, and inhibition of mitochondrial ATP synthesis inhibits electron flow. The difference in hydrogen ion concentration between the matrix of actively respiring mitochondria and the intermembrane space is the foundation of the chemiosmotic coupling mechanism.

The potential energy of the proton gradient that has formed between the inter-membrane space and matrix of the mitochondria is the immediate energy source that propels ATP synthesis by ATP synthase during oxidative phosphorylation. The pumping of protons that occurs along with the exchange of electrons is what produces the hydrogen ion gradient.

Answer:

CARBOHYDRATE DIGESTION AND ABSORPTION

For dietary carbohydrates to be utilized by the body, they must be converted during digestion to monosaccharides. In addition to starch, the other major dietary carbohydrates are the disaccharides lactose and sucrose, and the monosaccharide fructose. The monosaccharides produced by complete digestion of these dietary carbohydrates are glucose, galactose, and fructose.

The digestive process begins with salivary amylase, which randomly cleaves the α-1,4 linkages of starch. Although amylase digestion begins in the saliva, pancreatic α-amylase is more important to the complete digestion of starch (Fig. 19-1). Starch is degraded first to dextrins and then to a mixture of glucose, maltose, and isomaltose (containing the α-1,6 linkages that are not digested by amylase).

The major disaccharidases, located in the brush border of the intestinal lumen, are

•

Maltase—hydrolyzes maltose

•

Sucrase-isomaltase—hydrolyzes sucrose and isomaltose

•

Lactase—hydrolyzes lactose

Whenever lactose goes undigested, it is not absorbed and passes into the large intestine. Here lactose is acted on by the intestinal flora that ferment it, producing large quantities of CO2, hydrogen gas, methane, and organic acids; the last irritate the intestines, increasing intestinal motility. All these products have only one way out. Thus, the symptoms that characterize lactose intolerance are bloating and flatulence and, in extreme cases, a frothy diarrhea. Lactose intolerance is least common in Northern Europeans and their descendants and most common in descendants of Asian, African, and South American origin.

HISTOLOGY

Brush Border Dynamics

The unstirred brush border of the intestinal lumen consists of finger-like processes, known as microvilli, of the surface absorptive cells. Many enzymes associated with the process of digestion and absorption are located on the surface of these microvilli. This allows the products of digestion such as free fatty acids, amino acids, and monoglycerides to be absorbed by the cells rather than be swept into the lumen itself.

Claim: Using pyruvate as the final electron acceptor in an anaerobic process allows for the recycling of NAD+.

Evidence: During anaerobic respiration, the breakdown of glucose begins with glycolysis. In this process, glucose is broken down into two pyruvate molecules, which also generate ATP and NADH.

Under anaerobic conditions, pyruvate becomes the final electron acceptor instead of oxygen. Pyruvate is then converted to lactate or ethanol and CO2, which regenerates NAD+ from NADH.

Reasoning: In the absence of oxygen, cells rely on anaerobic respiration to generate energy. During glycolysis, glucose is broken down into pyruvate, which generates a net of two ATP molecules and two NADH molecules. In order for glycolysis to continue, NADH must be recycled back to NAD+.

However, without oxygen, the electron transport chain cannot occur, and the NADH cannot be oxidized. Instead, pyruvate acts as an alternative electron acceptor, which is converted to lactate or ethanol and CO2. This reaction allows NADH to transfer its electrons to pyruvate, regenerating NAD+ in the process. As a result, glycolysis can continue to generate ATP, and the cell can survive under anaerobic conditions.

Answer:

In humans, blood pressure is usually measured indirectly with a special cuff over the brachial artery (in the arm) or the femoral artery (in the leg). There are two pressures measured: (1) the systolic pressure (the higher pressure and the first number recorded), which is the force that blood exerts on the artery walls as the heart contracts to pump the blood to the peripheral organs and tissues, and (2) the diastolic pressure (the lower pressure and the second number recorded), which is residual pressure exerted on the arteries as the heart relaxes between beats. In healthy individuals, systolic pressure is normally between 90 and 120 millimetres of mercury (mmHg).

What is Adolescence?

Adolescence is a stage of physical and psychological development that normally occurs between puberty and maturity. Adolescence is commonly connected with adolescence, however its physical, psychological, or cultural manifestations might begin sooner and end later. Puberty today usually starts at preadolescence, especially in females. Physical and cognitive development can continue past the adolescent years. Age is simply an approximate indicator of adolescence, and researchers have yet to agree on a specific description.

Temperament is an important part of children's psychological functioning and is thought to remain rather stable throughout childhood. However, little research has been conducted to examine temperament stability from early childhood to early adolescence.

When an algae from the ocean is placed in fresh water, the water environment around the algae will become hypotonic in comparison to the algae's cytoplasm.

The high concentration of salt and other solutes in the ocean water creates a hypertonic environment for the algae, while the low concentration of solutes in the freshwater creates a hypotonic environment.

This change in osmotic pressure will cause water to move into the algae cells, causing the cells to swell. If the water uptake becomes excessive, the cells may burst and the algae may die.

However, if the algae is able to adjust its internal salt concentration, it can survive in freshwater. This process is called osmoregulation.

Answer:

First what is it? Carbon cycle is, nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.

1.Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.

2.Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.

3.Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years.

4.Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration.

5.Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels. Of this massive amount, 3.3 billion tons stays in the atmosphere. Most of the remainder becomes dissolved in seawater.

6.Carbon moves from the atmosphere to the oceans. The oceans, and other bodies of water, absorb some carbon from the atmosphere. The carbon is dissolved into the water.
