HYPOTHESIS: If 2 chambers of water are poured side-by-side, the warmer water will mix the cooler layer because it
Answer:
The warmer water will mix with the cold water because it will migrate to the surface.
Explanation:
If hot water and cold water are poured in the same place, it means that they will occupy the same space. However, hot water has a lower density than cold water, which means that hot water molecules are lighter and will tend to rise towards the surface.
However, when migrating to the surface, the hot water molecules will pass between the cold water molecules, causing the two waters to mix. In this process, the hot water will transfer heat to the cold water and cool until the two waters have the same temperature.

pls answer asap, would be very appreciative:)
Answer:
d
Explanation:
When a scientist uses radiometric dating to determine the age of a rock specimen, would he use a radioactive element with a short half life, say a half-life of less than 10,000 years, or a radioactive element with a long half-life, say a half-life greater than 1 billion years?
Answer:
He will use a radioactive element with a long half life of greater than 1 billion years
Explanation:
Rocks are an aggregation of solid mass which is usually rich in minerals. The age of rocks is established using radiometric dating method.
According to Oxford Dictionary, radiometric dating is "a method of dating geological specimens by determining the relative proportions of particular radioactive isotopes present in a sample."
The age of rocks can only be ascertained using isotopes that have very long half lives because many of these rocks are very old (aged billions of years) hence their age can only be determined using elements that has a half life greater than 1 billion years.

Is RNA made in the nucleus or
cytoplasm? Explain how you know.
Answer:
They're non-coding RNAs that help the messenger RNAs to undergo the protein translation process. These RNAs, like the other messenger RNAs, are made in the nucleus, but ribosomal RNAs are made in the nucleolus which is a very specific part of the cell nucleus.
Explanation:
Answer:
RNA is synthesized in the nucleus and then exported to the cytoplasm.
Explanation:
Ribonucleic acid is a polymeric molecule essential in various biological roles in coding, decoding, regulation and expression of genes. RNA and deoxyribonucleic acid are nucleic acids

Am I right? Please someone help me
Answer:
A. 17,100
Explanation:
The half life of carbon-14 is around 5,700 years. When the shell contains 50% of its original carbon-14, 5,700 years have passed. 25% means another 5,700 years have passed, meaning 11,400 years in total have passed. 12.5% means another 5,700 years have passed, meaning 17,100 years have passed in total.

The study of evolutionary relationships that includes a branching pattern showing lineages diverging is called... *
Answer:
Phylogenetic tree
Explanation:
A phylogenetic tree is a tree that is responsible for showing the different relationships with respect to evolution between species that are considered to have a common offspring. The species of interest are shown at the tips of the branches of the tree in question. The branches are connecting with each other, representing the evolutionary history of the species, being the way in which we think that they evolved starting from a common ancestor through various divergence events (when two branches separate).

Describe what the male beetle has to do In order to successfully mate with the female
Answer: they would maybe have to fight with the other beetles to tr and get the females attention
Explanation:
pls mark brainliest
The male beetle must struggle to successfully mate with the female if where they go there is more than one male courting the female.
How do beetles mate?Female beetles of this species dig tunnels in the dung, where males mate with them. If a male enters a tunnel that is already occupied by a rival, they will fight, trying to pull the other out.
With this information, we can conclude that the male beetle must struggle to successfully mate with the female if where they go there is more than one male courting the female.

After the mRNA is formed, what happens?
A. It binds permanently with DNA molecule.
B. It moves out of the nucleus and into the cytoplasm.
C. It disassembles and the process repeats.
Answer:
The correct answer is - B. It moves out of the nucleus and into the cytoplasm.
Explanation:
mRNA formation is known as transcription which is the first process of protein synthesis in which mRNA is formed from DNA sequence with help of RNA polymerase enzyme.
After forming the mRNA sequence this mRNA moves out of the nucleus and reaches the cytoplasm where it performs the second process called translation with help of tRNA and ribosome to produce an amino acid chain.
Answer:
B. It moves out of the nucleus and into the cytoplasm.
Explanation:
After the mRNA is formed, it moves out of the nucleus and into the cytoplasm.
which 5 kingdoms that do have cell walls?
Answer: There are six kingdoms: Archaebacteria, Eubacteria, Protista, Fungi, Plantae and Animalia. Organisms are placed in a specific kingdom based upon a variety of factors, including cell wall structure. As the outermost layer of some cells, the cell wall helps maintain cellular shape and chemical equilibrium.
In this assignment, you will use simulations to analyze how climate, resources, and habitat size affect
carrying capacity. You will then look at another simulation to analyze the effects of certain factors that
affect biodiversity and populations. Finally, you will write and revise a conclusion on how human activity
affects biodiversity
Answer:
Directly affects.
Explanation:
Climate, resources, and habitat size directly affect carrying capacity of an ecosystem. Favourable climatic and environmental conditions increases the population of organisms to its maximum limit. More resources leads to increase in population of species in an ecosystem until carrying capacity. Habitat size also depends on carrying capacity which means higher carrying capacity can leads to bigger habitat size. Climatic change, Habitat destruction, introduced and invasive species and genetic pollution are factors that effect both biodiversity and population. Human activities causes pollution, destruction of habitat by cutting trees etc affects biodiversity.
Are RNAs processed before translation is able to occur in Prokaryotes? Do only mRNAs undergo processing and maturation in Eukaryotes?
Answer: RNAs are not processed before translation in prokaryotes, this process only takes place in eukaryotes.
Explanation:
Messenger RNA or mRNA is a single-straded ribonucleic acid that transfers the genetic information from the DNA (deoxyribonucleic acid) molecule of the cell nucleus to a ribosome (which are the machinery responsible for protein synthesis) in the cytoplasm. mRNA determines the order in which the amino acids of a protein will be joined and acts as a template or pattern for the synthesis of that protein. To accomplish this, the DNA molecule must be transcribed into an RNA molecule, which is used for protein synthesis.
The messenger RNA obtained after transcription is known as primary transcribed RNA or precursor RNA or pre-mRNA, which in most cases is not released from the transcription complex in a fully active form, but in eukaryotes it must undergo modifications before it can perform its function (RNA processing or maturation). These modifications include:
Elimination of fragments (splicing): In most cases, the mRNA undergoes the removal of internal, non-coding sequences called introns, and the connection of exons. This does not occur in prokaryotic cells, as they do not have introns in their DNA.Protection by CAP: Addition to the 5' end of the structure called "cap" or "capping", which is a modified guanine nucleotide, 7-methylguanosine triphosphate, via a 5'-5' triphosphate linkage, instead of the usual 3',5'-phosphodiester linkage. This cap is necessary for the normal RNA translation process and to maintain its stability. Polyadenylation signal: Addition to the 3' end of a poly-A tail, a long polyadenylate sequence, whose bases are all adenine. Its addition is mediated by a sequence or polyadenylation signal (AAAAAA), located 11-30 nucleotides upstream of the original 3' end. This tail protects the mRNA from degradation, and increases its half-life in the cytosol, so that more protein can be synthesized.The mature mRNA (in eukaryotes) is transferred to the cytosol of the cell through pores in the nuclear envelope. Once in the cytoplasm, ribosomes are coupled to the mRNA. However, in prokaryotes, ribosome binding occurs while the mRNA strand is being synthesized. After a certain amount of time, the mRNA is degraded into its component nucleotides by ribonucleases. So, the transcription and translation processes are carried out in a similar way as in eukaryotic cells but they occur simultaneously. But, the fundamental difference is that, in prokaryotes, the messenger RNA does not undergo a maturation process and, therefore, no cap or tail is added and no introns are removed. Moreover, it does not have to leave the nucleus as in eukaryotes, because in prokaryotic cells there is no defined nucleus.
So, RNAs are not processed before translation in prokaryotes, this process only takes place in eukaryotes.
