Organisms adopt different strategies and structures to make sure their offspring survive. Match each species with the reproductive strategy or structure it uses. elephant Answer 1 frog Answer 2 pine cone Answer 3
Answer/Explanation:
From the diagram attached below, we can match the reproductive strategy or structure each species uses which ensures the survival of their offspring as follows:
1. Elephant => herds young in to center of group
The Elephant usually keep their young ones at the middle of the herds to prevent their young ones from being preyed on easily by predators.
2. Frog => Pduces many offspring at once to protect against high predation risk
The young one of frogs are easily preyed on by predators, and as such, to ensure more of their offspring survive, they produce so many offspring in a breeding season, in order to increase thee survival of their offspring to the next generation.
3. Pine cone => Protects offspring until environmental conditions are ideal for growth
A scientist observes the motion of a certain type of vesicle around the cell. She notices that vesicle movement ceases when colchicine is added to the culture medium. What conclusion can she draw?
Answer:
colchicine inhibits microtubule function, it is most likely that the
vesicular movement is orchestrated or produce by microtubules.
Explanation:
Microtubules is organelle in the cell which give shape to the cell and help transport vessicles, granules and some organelles inside the cell.
Colchicine is a chemical substance that inhibit microtubules function and for gout treatment.
When colchicine is added to the microtubules, vessicles movement is produce by microtubules.

if you denature a protein, you increase the ability to react. true or false
Answer:
False
Explanation:
Denaturing a protein involves deforming its shape by removing it from its optimum temperature, pH, salinity, etc. This decreases its efficiency because its optimum shape is not present, meaning that its ability to react is decreased.
I want some hand with this please
1) One reason why deforestation is occuring because people need wood from trees to build things, therefore, leading them to cuting countless of trees.
2) One environmental problem that results from widespread deforestation is that the carbon dioxide they would normally use remains in the atmosphere, therefore, promoting erosion.
3) One way to lessen the effects of deforestation is by re-planting the cut-down trees and by cutting down less trees.

consider a molecule of the polymer, polyethylene, and a protein molecule as if they were strings of beads. How would the string representing polyethylene differ from that representing a protein
Answer:
When a macromolecule contains repeated similar sub units of a particular molecule:such a repeated units are called polymers.
Therefore, polyethylene is a micromolecule of repeated subunits called ethylene formed during polymerization..Therefore, the small units joined together to form polyethylene are ethylene.These are alkene hydrocarbons,which are similar in structure with the carbon atoms linked by double bonds.When the Pi bonds of the double bonds breaks. hydrogen atoms forms free covalents bonds in all these sub units.
However, polypeptides is made of of 20 different amino acids, connected by peptides, disulfide and other bonds.Therefore the protein molecules will be different from the polyethylene and polymers. This is because each of the 20 amino acids has different R-groups, and It is this R-groups that determine the functional characteristics displayed by each amino acid sub- units.Therefore, the characteristics of a protein molecule will be determine by the type of Amino acids it contains.
Thus the beads of polyethylene will be the same, but different in proteins

Do Now: b) Complete the following mRNA Strand: GCATACAGT (Be sure to look if it is asking for DNA or mRNA. DNA is GCAT and mRNA is GCAU. All answers must be in capitals when writing out bases, or the will be considered wrong.)
Answer:
CGUAUGUCA
Explanation:
Firstly, the strand in the question is a DNA strand because it contains the Thymine base, which is only found in a DNA molecule. The process of changing a DNA molecule into RNA molecule (specifically a messenger RNA) is called transcription. Transcription is done using the complementary base pairing rule, which states that Adenine (A) will always pair with Thymine (T), and Guanine (G) will always pair with Cytosine (C).
In the case of transcription, the Thymine bases will change to Uracil (U), since Uracil is only found in the RNA molecule. That is, A-U and G-C. Hence, a DNA strand that reads: GCATACAGT will produce a mRNA strand CGUAUGUCA.
Which part of the chemical equation is incorrect?
Answer: Thus the coefficient of oxygen is incorrect.
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The given chemical equation for combustion of butane is
[tex]2C_4H_{10}+10O_2\rightarrow 8CO_2+10H_2O[/tex]
The balanced chemical equation for combustion of butane is :
[tex]2C_4H_{10}+13O_2\rightarrow 8CO_2+10H_2O[/tex]
Thus the coefficient of oxygen is incorrect.

Explanation:
Puerto Rico, Cuba, Jamaica, and Hispaniola have species of anole lizards with distinct body types, including the grass lizards, which have long tails; the canopy lizards, which have large toe pads; and the twig lizards, which have short legs. Anole species with each of these three body types exist on each of the:_________
Answer:
four islands.
Explanation:
Anole lizards includes different types of lizards such as the canopy lizards, the grass lizards and the twig lizards and are found in Puerto Rico, Cuba, Jamaica, and Hispaniola.
Anole species with each of these three body types exist on each of the four islands because of interisland migration events.
The anole species share common ancestor with each other in comparison to other lizard species, interisland migration events allowed anole species to get evolved by natural selection process in different islands including Puerto Rico, Cuba, Jamaica, and Hispaniola.
Hence, the correct answer is four islands.

What is the population density if there are 40 squirrels in 4 square miles?
Answer:
10 squirrels/ square mile
Explanation:
Population density can be found by dividing the number of individuals by the area of the land they live in.
population/ land area
We want to find the population density for 40 squirrels that live in 4 square miles. Therefore, the population is 40 squirrels and the area of the land is 4 square miles.
population / land area
40 squirrel/ 4 square miles
Divide 40 by 4
40/4=10
10 squirrels/ square mile
The population density is 10 squirrels per square mile.
How does filtration occur during the formation of urine ?
Each of your kidneys is made up of about a million filtering units called nephrons. Each nephron includes a filter, called the glomerulus, and a tubule. The nephrons work through a two-step process: the glomerulus filters your blood, and the tubule returns needed substances to your blood and removes wastes.

During replication, the strands of a double stranded DNA separate when the bonds are broken between their paired bases.
Explain why, in terms of the genetic code, it is important that the molecule separated between the bases and not at some other point. (Remember the bases are letters that spell out specific traits for the organisms).
Answer:
During the process of replication, the double stranded DNA separates when several enzymes act to break the bond between base pairs in two strands.
There are four base pairs in DNA that includes thymine, cytosine, guanine and adenine. these bases determines DNA's instructions, or genetic code. The four bases are allowed to encode the sequence of amino acid residues in proteins by making a pair of three codons that carry genetic codes and helps on the process of transcription and translation.
For example: if the DNA sequence is having bases ATGCCGG, its complementary base pair will be UACGGCC, lets make pair of three codons UAC that codes for amino acid Tyrine and GGC codes for glycine.
Bases are components of nucleotide and nucleotide are the basic building blocks of DNA and RNA.
If DNA will separate from any other point then it will not able to carry the genetic code. hence, DNA separates between the bases only.
It is important that the molecule is separated between the bases and not at some other point because nucleotide order is fundamental to obtain two genetically identical DNA molecules.
What is DNA?DNA is a self-replicating molecule that is fundamental for life by assuring of the perpetuity of the genetic material.
During DNA replication, different enzymes act to produce two genetically identical DNA molecules.For this purpose, enzymes must copy with absolute fidelity the order of the nucleotide sequence in the DNA molecule.In conclusion, it is important that the molecule is separated between the bases and not at some other point because nucleotide order is fundamental to obtain two genetically identical DNA molecules.
