The density of water is 1 gram per milliliter, so objects with a relative density less than 1 gram per liter will sink.
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).
What is density?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.

Earth's___ and _____ affect the relative amounts of solar radiation regions receive
Earth's distance and tilt affect the relative amounts of solar radiation regions receive.
Explanation:Earth's distance and tilt affect the relative amounts of solar radiation regions receive. There are no options provided in the question, but this is the correct answer. The earth's orbit is not circular and the earth rotates in a tilted orbit. Whenever the south pole is tilted towards the sun, then the south pole will get more solar radiation than the north pole. The Earth absorbs most of the energy reaching its surface and a small fraction is reflected. In total, approximately 70% of the incoming radiation is absorbed by the atmosphere and the Earth's surface while around 30% is reflected back to space and does not heat the surface.

4. All enzymes have an optimal temperature at which they work as well as an optimal pH for their activity. Does this mean that enzymes only work at those specific temperatures and pH optimums? Briefly explain your answer using evidence from the unit that supports your answer.
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.

ou are testing a patient's fecal sample for the presence of Clostridium difficile. Which of these staining procedures would give you the best evidence that the patient's sample contains bacteria from the Clostridium genus? Group of answer choicesendospore staingram stainsimple stainacid fast stain
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.
Draw comic strip should include an example of transcription (DNA to mRNA) and an example of translation (mRNA to amino acid, and include tRNA) as well as the location of both in the cell.
We have to consider that the DNA is first transcribed into pre mRNA in the nucleus of the cell by the RNA polymerase. After this process, the non-coding fragments (introns) of the molecule are spliced by ribonucleoproteins (snRNP). Eventually, each end of the pre mRNA is modified, being a modified nucleotide named CAP joined to the 5' end, and a polyA (poly Adenine) tail at the 3' end before the now matured mRNA gets out of the nucleus to the cytoplasm.
At this point, the mRNA will be recognized by ribosomes, which will synthesize each group of three nucleotides (codons) into amino acids in a process called translation, by the action of tRNA, and finally joined into a new protein.
Note that A, P, and E are sites of the ribosomes, being A the position where first arrives the mRNA.
Which of the following pairs of base sequences could form a short stretch of a normal double helix of DNA?

B) 5'-AGCT-3' with 5'-TCGA-3'
C) 5'-GCGC-3' with 5'-TATA-3'
D) 5'-ATGC-3' with 5'-GCAT-3'
E) All of these pairs are correct.
The pairs of base sequences could form a short stretch of a normal double helix of DNA is:
D) 5'-ATGC-3' with 5'-GCAT-3'
In DNA, the code letters are A, T, G, and C, which stand for the chemical substances adenine, thymine, guanine, and cytosine, respectively. Under normal occasions, the nitrogen-containing bases adenine (A) and thymine (T) pair collectively, and cytosine (C) and guanine (G) pair collectively. The binding of those base pairs forms the structure of DNA.
Because of the base pairing, the DNA strands are complementary to each different, run in opposite guidelines, and are referred to as antiparallel strands.
Complementary base pairing is important in DNA because it lets the base pairs be arranged in the maximum energetically favorable way; it's miles crucial in forming the helical structure of DNA. it's also critical in replication as it allows semiconservative replication.
You could determine the sequence of a complementary strand if you are given the series of the template strand. These strands are complementary, with each base in one sticking to its partner on the alternative. The A-T pairs are linked by means of two hydrogen bonds, whilst the G-C pairs are connected through three hydrogen bonds.

Explain at the chemical level why plants die when they are not watered.
Your answer must explain the importance of water to photosynthesis and
describe specifically how photosynthesis would be affected and
effectively shut down with the loss of water.
Answer:
All living things need to water to survive. This is because all living things are mostly made of water and since they lose water in different ways, they need to get more water to stay the same size. So if a plant does not get enough water, it will shrink. If it goes long enough without water it will die because the plant uses water for a lot of different jobs needed to keep the plant alive.

A biologist found an asymmetrical organism. A part of the organism was injured, but it was able to repair itself through regeneration.
Because the organism is asymmetrical and it was able to regenerate, it’s probably
.....
, and belongs to the phylum
....
.
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.

What is the difference between chromosomes, sister chromatids, non-sister chromatids, separated chromatids?
Chromosomes are structures of nucleic acids and protein carrying genetic information in the form of genes.
The chromosome is composed of two sister-chromatids.
During meiosis and mitosis, the sister chromatids are separated to separate half of the geentic material and create a new cell.
The difference between sister chromatids and non-sister chromatids is that sister chromatids have the same alleles in the same place and non-sister chromatids have different alleles in the same place. Non-sister chromatids will have the same length and configuration, but those different alleles will represent different types of the same characteristic (for example: different colors of fur). But they look the same as sister chromatids.
