A biologist is writing a report about a group of rattlesnakes that all live in the state of Florida. All rattlesnakes in this group can breed with one another and produce offspring that can reproduce together. The report includes statistics about the number of these rattlesnakes, their breeding rate, and the ranges of their sizes and other traits. In this report, the biologist is describing? A.a community in Florida. B.a biome in Florida. C.a population in Florida. D.an organism in Florida.
The correct answer is option C, a population in Florida
The population description is an efficient language is termed as demographics. The descriptive components of the demographics are –
a) Population Size – It gives the number of individuals within a population
b) Population Density – It defines the size of a population with respect to the space occupied by it
c) Age Structure of the Population – It categorizes different individuals in a population group to different age sections
d) Fecundity – It describes about an individual that is able to produce during a given period of time
e) Morality – It gives the death and birth rate of a population
f) Sex ratio

A. 1,2,4,5,3 B. 2,1,4,5,3 C. 1,4,3,5,2 D. 2,5,3,1,4 please give good explanation
Which of the following is NOT true about ATP? glucose breaks down into ATP without any initial energy input. (It just spontaneously happens) Energy is stored in the bonds of the phosphate group cells make and use ATP ferns, slime molds, dogs, and fish all use ATP for energy in the cells
Why did Mendel prevent his plants from self-pollinating? to control the crossing of the traits in order to insure that each plant's offspring would remain identical to the parents to maintain a pure strain so they could not produce offspring
The idea of preventing plants from self-pollinating is to control the crossing of the traits. If plants were self-pollinating, he could not know if the traits are inherited from the same plant or from the other. By preventing this, he could cross parents with known phenotype and that way learn about crossing process and inheriting process.
The primary function of the chromosome is to– A. store the genetic instructions needed to specify traits. B. release energy by breaking down food molecules. C. transport waste materials rapidly out of the cell. D. relay messages between different cells in animals.
What is the role of natural selection in evolution? Natural selection is a specific mechanism of evolution in which the heritable traits (characteristics) help an organism to survive his generation. Natural selection is a specific mechanism of evolution in which the heritable traits (characteristics) help an organism to survive and reproduce successfully. Natural selection is a specific mechanism of evolution in which all acquired traits (characteristics) help an organism to survive and reproduce successfully
Answer: DNA molecules is packaged into chromosomes which are found in the cell nucleus.
Explanation: Chromosomes are made up of DNA (deoxyribonucleic acid) coiled around proteins called histones that support its structure. In humans cells there are 23 pairs of chromosomes, that makes a total of 46. Twenty-two of those pairs are autosomes while the 23rd pair is called sex chromosomes.
The genetic information is stored in the structure of the DNA, so this molecule is the hereditary material in almost all living organisms. That is why it contains the instructions to construct components of the cell.
Which evidence supports the endosymbiotic theory? Select all that apply. Mitochondria and chloroplasts have a separate, simpler DNA from the nucleus DNA of a eukaryotic cell. These organelles' DNA resembles the DNA of prokaryotic cells. Mitochondria and chloroplasts self-replicate by a cell division process similar to binary fission, which is the way prokaryotes divide. The way mitochondria and chloroplasts synthesize proteins within the eukaryote cell is more similar to prokaryotes than to eukaryotes. There are living examples of prokaryotes, like cyanobacteria, that share similar features with both mitochondria and chloroplasts of eukaryotic cells. Observations of prokaryotic cells engulfing other prokaryotic cells and the engulfed cells becoming the organelles have been recorded.
The answers are the first four options... not the last. Hope this helped
In a dihybrid cross, the F2 will have nine genotypes, but only four phenotypes because the (Homozygous, Heterozygous) genes cause the (Recessive, Dominant) traits to mask the (Dominant, Recessive) traits.
The answers is:
In a dihybrid cross, the F2 will have nine genotypes, but only four phenotypes because the Heterozygous genes cause the Dominant traits to mask the Recessive traits.

The onion cell would not have a well-defined nucleus but would have a thick cell wall and ribosomes.
I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!
The first. That is the answer
A cell is a tiny world of elements, one of which is the vacuole. Found in both plant and animal cells, a vacuole is a fluid-filled pocket in the cell's cytoplasm that serves varying functions depending on the cell's requirements.
I hope my answer helped.
Which of the gazelle’s naturally selected traits is shown in this picture to be an evolutionary advantage? a)feeding only at certain times of the day b)coat color for blending in with dry grass c)specialized gut due to a diet of grasses d)specific gender roles to diminish predation
The answer is B: coat color for blending in with dry grass
Why do the atoms in the top rows in the Periodic Table have higher electronegativity than atoms in lower rows? The electrons of those atoms are farther from the nucleus. The electrons of those atoms are closer to the nucleus. The electrons of those atoms are part of the nucleus. When there is unequal sharing between two atoms of the electrons in a bond, which type of bond is it? polar covalent electronegative ionic nonpolar covalent
For 1: The correct answer is the electrons of those atoms are farther from the nucleus.
For 2: The correct answer is polar covalent.
- For 1:
Electronegativity is defined as the property of an element to attract a shared pair of electron towards itself. The size of an atom increases as we move down the group because a new shell is added and electron gets added up.
As, the size of an element increases, the valence electrons gets away from the nucleus. So, the attraction between the nucleus and the shared pair of electrons.
Hence, the correct statement is the electrons of those atoms are farther from the nucleus.
- For 2:
A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms. It is also defined as the bond which is formed due to the unequal sharing of electrons between the atoms.
An electronegative atom is the one which attracts the shared pair of electron towards itself.
Ionic bond is formed when there is complete transfer of electron from one atom to another atom.
Non-polar covalent bond is defined as the bond which is formed when there is no difference of electronegativities between the atoms. It is also defined as the bond which is formed due to the equal sharing of electrons between the atoms.
Hence, the correct answer is polar covalent.
C. a stop codon is reached.
Translation is the process by which proteins are synthesised from mRNA. It ends in the termination stage when a stop codon is encountered. Normally during translation the A-site of ribosome is responsible for binding the complementary codon on the mRNA with the incoming tRNA. The tRNA with the polypeptide chain is hold by the P-site.
During termination, a stop codon ( UAA, UGA or UAG) is encountered by the A site in ribosome and is then recognised by release factors. Release factors enter the P site and fit there leading to disassembly of entire ribosome/mRNA complex. A water molecule is added to the last amino acid of the chain which separates it from the tRNA molecule and leads to its release.
