Answers
Answer :
The possible contents in 1st test tube are meat and clean rain.
The possible content in 2nd test tube is olive oil.
The possible contents in 3rd test tube is tomatoes.
Explanation:
pH : It is defined as the negative logarithm of hydrogen ion concentration.
The main use of pH paper is to determine is a solution is acidic, basic or neutral.
The range of pH paper is 1 o 14 with different color.
If the solution is acidic then the value of pH is less than 7.
If the solution is basic then the value of pH is more than 7.
If the solution is neutral then the value of pH is equal to 7.
According to the question,
The possible contents in 1st test tube are meat and clean rain.
The possible content in 2nd test tube is olive oil.
The possible contents in 3rd test tube is tomatoes.
Answer:
Yellow pH paper: meat, green pH paper: olive oil, and the orange pH paper: tomatoes

What classification of decay is located on the gingival third on the facial or lingual surfaces of teeth
Answers
Answer:
Smooth-surface decay.
Explanation:
Dental caries is a multifactorial infectious disease of the hard tissues of the tooth (enamel and dentin) that arises on the surface of the tooth and can spread to the pulp. Smooth-surface decay are dental caries that originate on the smooth surfaces of the proximal general teeth, or in the gingival third of the facial and lingual surfaces. This cavity forms when plaque builds up and bacteria are not killed on the flat surface of the teeth.

Science enhances a person's existence at all levels, from an excellent rating to worldwide problems.Bacterial species have evolved over millions of years to fill almost every available environmental niche on this planet. Despite this impressive radiation, bacteria are still limited by the availability of carbon and nitrogen sources for their metabolisms. Bacteria may express many different proteins required for uptake and utilization of these compounds for use in their metabolisms. Organic compounds containing carbon and nitrogen are required for both anabolic and catabolic reactions that comprise a cell’s metabolism. Not all bacterial species have the same abilities, so you can use this characteristic to differentiate bacterial species by determining which carbon- and nitrogen-containing media support the growth of the bacteria. Determine whether the following enzymatic reactions are anabolic or catabolic and place them within the correct bin.

2. ammonia is added to glutamate to form glutamine.
3. four amino acids are linked together to form tetrapeptide.

5. starches are digested into individual glucose molecules.
6. ribose and inorganic phosphate are bonded to form a nucleotide base.
Answers
Answer:
1. Glucose breaks down into two pyruvates. CATABOLIC
2. Ammonia is added to glutamate to form glutamine. Anabolic
3. Four amino acids join to form tetrapeptides. Anabolic
4. A uracil base is added to an mRNA strand by RNA polymerase. Anabolic
5. Starches are digested into individual glucose molecules. CATABOLIC
6. Ribose and inorganic phosphate join together to form a nucleotide base. Anabolic
Explanation:
Chemical reactions are classified as anabolic and catabolic depending on whether they form or disintegrate structures, yielding energy to the medium or taking energy from the medium.
Anabolic reactions are those that take energy from the environment and therefore synthesize very complex molecules, of various bonds such as glycogen, starch, among other polysaccharides.
On the other hand, catabolism leads to the destruction of the unions of a chemical product, that is why they have greater entropy and is thus the greatest disorder.
Catabolism releases energy to the environment, it releases it.
For an anabolic reaction to happen, there must be a catabolic one, since it takes the energy released by catabolism, and for a catabolism to happen, an anabolism must first have arisen, that is, the formation of a molecule or particle that is dissociates.

Answers
Answer:
The correct option is (D).
Explanation:
Newton's second law of motion gives the relationship between the force and acceleration of an object. It can be given by :
F = ma
It means that the force is directly proportional to both mass and acceleration. If the acceleration increase, force will increas. It would mean that "The direction of the force and the direction of acceleration must be the same as each other".

Design a controlled experiment to test the effect of water temperature on a goldfish. Be sure to include your hypothesis, independent variable, independent variable, as well as the experimental and control groups in your experiment
Answers
Answer:
The experimental design involves three fish tanks each containing goldfish and sympatric non-competitive species populations composed of 100 individuals (N = 100), which must be maintained in three different temperature treatments.
Explanation:
1- First fish tank: water to the same temperature than its natural environment (for example 25 C)
2- Second fish tank: water temperature 2°C higher than its natural environment (27 °C)
3- Third fish tank: water temperature 2°C lower than its natural environment (23 °C)
Null hypothesis: temperature treatments does not modify the survival of goldfish populations
Independent variable: temperature treatments
Dependent variable: Goldfish survivance over n generations
Negative control: First fish tank (water to the same temperature than natural environment)
Control group: sympatric non-competitive species populations
A cardiac muscle cell is: A. a voluntary muscle just like skeletal muscle. B. contracts spontaneously. C. is joined to other cardiac muscle cells by structures called intercalated discs. D. has numerous nuclei. E. Two of the statements above are correct
Answers
Answer:
E. Two of the statements above are correct i.e. options B and C
Explanation:
Cardiac muscles, also known as myocardium, are one of the three types of muscles found in the heart (the other two being skeletal and smooth muscles). Cardiac muscle cells are striated and branched in structure, with only one nucleus located centrally i.e. mono-nucleated.
Unlike the skeletal muscles, cardiac muscles are involuntary muscles controlled by certain parts of the brain. The cells that make up the cardiac muscles are connected to one another by structures called intercalated discs. Also, cardiac muscle cells contract spontaneously i.e. internally. Hence, options B and C are correct

The right atrioventricular valve (tricuspid) regulates the opening between the _________ and the _________.
Answers
Answer:
The right atrioventricular valve (tricuspid) regulates the opening between the right atrium and the right ventricle.
Explanation:
Valves are gates that allow the connection between atria and ventricles. The two valves located on the right side (tricuspid and pulmonary) direct the incoming blood from the body to the lung, where it is oxygenated; from there it returns to the left atrium, to later pass through the mitral and aortic valves. The left atrium connects to the left ventricle through the mitral valve and the right atrium connects to the right ventricle through the tricuspid valve.

A. they can not absorb enough carbon from water.
B. they cannot absorb carbon directly from the air.
C. they are in competition with plants for available
carbon.
D. they require carbon to perform photosynthesis.
Answers
Answer:
B. they cannot absorb carbon directly from the air.
Explanation:
Carbon cycle refers to the series of processes through which carbon is exchanged between living and non living components of the environment. During the carbon cycle, animal organisms feed on one another in order to obtain energy, a characteristics that makes them HETEROTROPHIC.
Unlike plants, animals cannot perform photosynthesis, which turns solar energy into biomass (carbon-based). Plants get their carbon source (CO2) directly from air via the stomata on their leaves. Animals, on the contrary, cannot get carbon this way, hence, they need to feed on other animals to get their carbon and energy source.

Characteristics that defines a biological organisms are passed down from parent to offspring during sexual reproduction. These characteristic can change over time due to mutation of genes. The new characteristics can either become more dominant; if it enhances the organisms chances of survival, or can die away or even lead to the complete wipe out of the species, if it does not increase the odds of survival of the organism. The mechanism of the development, or eradication of these characteristics is through natural selection, and sexual selection.
