The statement that is true is as follows: the density of water is 1 gram per milliliter, so objects with a relative density greater than 1 gram per milliliter will sink (option C).

Density is the measure of the mass of matter contained by a unit volume. The density of a liquid substance is a determinant of whether the substance will float or sink in water.

Water is a liquid substance with a density of 1 gram per millilitres (1 g/mL). This suggests that any substance with greater density than that of water will sink while any substance with lesser density than water will float.

Density is a measure of how heavy something is compared to its size, hence, if an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float.

Therefore, according to this question, objects with a relative density greater than 1 gram per milliliter will sink.

Enzymes perform their functions within a specific temperature and pH range (which is specific for each enzyme in particular). In turn, within this range, there is a specific value at which they act in the most efficient way possible, which does not mean that they cannot on other values in the range. However, outside the limits of the range, the internal characteristic of enzymes can be affected and cause their denaturation, thus losing their capacity of action.

In order to answer this question, we must remember a bit of cellular metabolism, when mitochondria carry out the process of cellular respiration we can see that in the electron transport chain the final acceptor of electrons is oxygen. Therefore the correct answer for the question is option D oxygen.

To be considered as fit for evolution processes, a species must be able to adapt in its environment and with capacity to reproduce sucessfully. Ambrosia, for example, is an invasive species. It has the abillty to promote accelerated evolution due to its adaptibility to its environment. Zea mays is an excellent species for genetic analysis. Quercus also has evolutionary potential because of its physiological characteristics.

Of the following processes the one that is not associated with sexual reproduction is the binary fission, that is a asexual reproduction by a separation of an organism of the body into two new bodies.

A serum amylase is diluted 1/100 with a result of 45.0 U/L. The patient's actual amylase result is 4500 U/L.

Serum- Serum generally refers to the transparent fraction of any biological fluid, whether it comes from an animal or even a plant. For instance, the fluid released by serous glands is known as mammal serous (or serosal) fluid. The serum in blood is a clear, pale yellow liquid that is separated from of the blood and thus is free of blood cells & clotting components.

Amylase- The primary job of amylases is to hydrolyze all glycosidic linkages in molecules of starch, turning them to simple sugars. The three primary kinds of amylase enzymes—alpha, beta, and gamma—each affect the carbohydrate molecule in a different way.

Answer: False

Explanation: Having an autoimmune disease will not necessarily lead to death, many of them have a treatment which allows the patient to maintain his/her quality of life.

As a protocol, the sample must first undergo primary biochemical tests, one of which is gram staining. And although this stain can help us to identify bacteria of the Clostridium genus, such as gram + sporulated bacilli, a more specific test would be the endospore stain, since the clostridium genus produces endospores that are also easy to isolate, since they are more resistant to temperature than the vegetative form (not sporulated) of the bacterium. An example would be the Schaeffer-Fulton stain.

If the mating of 2 black guinea pigs produced 29 black and 9 white offspring, the genotypes of the parents would be heterozygous.

Expected phenotype ratio = 3:1 black to white

Expected genotypic ratio = 1 AA:2Aa:1aa

The mating of 2 black guinea pigs produced 29 black and 9 white offspring. The parents must be heterozygous.

Assuming the allele for the black trait is A while that of the white trait is a. The cross is between Aa and Aa.

    Aa    x    Aa

AA   Aa   Aa   aa

The black allele is assumed to be dominant over the white allele. Thus:

Phenotype ratio = 3:1 black to white.

The ratio of the offspring produced from the mating is 29 black to 9 white, which is roughly 3:1. Thus, the mating is between two heterozygous black individuals.

Expected phenotype ratio = 3:1 black to white

Expected genotypic ratio = 1 AA:2Aa:1aa

Answer: 1. The right answer is amphibian.

2.  The right answer is Mollusks.

Explanation:

1. Regenerating a limb is not possible in mammals, as in most vertebrates. But in amphibians such as the salamander yes!

This amphibian does it very well, capable of making tail, eye or snout too. For a very long time, scientists have been trying to understand this secret of the salamander, or that of the zebrafish, because the answer is scientifically interesting but also, of course, because we can hope to take advantage of it to imagine one day of medical treatment for injured members. Just over a year ago, an Australian team showed the role of macrophages, cells of the immune system.

2. Mollusks (Mollusca) are a branch of Lophotrochozoans animals. They are unsegmented animals, with bilateral symmetry sometimes altered. Their body usually consists of a head, a visceral mass, and a foot. The visceral mass is covered in whole or in part by a mantle, which secretes a calcareous shell. The nervous system includes a double periesophageal collar. The general cavity is more or less reduced to pericardium and nephridia.
