Which type of joints allows movement
Answers
Answer:
The correct answer would be - synovial joints.
Explanation:
Synovial joints are the joints that allow bones to move as these joints are able to great movement freely of the three structural joints. These joints have synovial fluid which helps and enabling the structures of the joints to move smoothly against each other.
They also called diarthroses which means freely movable. Ball and socket joints is a type of synovial joint that allows movements in all direction with help of muscles attached to it. Hip joint and Shouder joint are examples of such joint.
Answer:
Synovial joints
Explanation:
Synovial joints achieve movement at the point of contact of the articulating bones.
Synovial joints allow bones to slide past each other or to rotate around each other. This produces movements called abduction (away), adduction (towards), extension (open), flexion (close), and rotation.
If the carrying capacity of the pond is 1,500 for this species, what is the expected population size after one year
Answers
Answer:
450
Explanation:
A fish population of 250 in a pond has a maximum annual rate of increase of 0.8. If the carrying capacity of the pond is 1,500 for this species, what is the expected population size after one year?
The annual rate of increase in the population is 0.8 and the population is currently 250 in the pond, hence, the expected population size after one year can be calculated as thus:
Expected increase in the population = 0.8 x 250
= 200
Expected population size after one year = 250 + 200
= 450
Since a population of 450 has not exceeded the carrying capacity of the pond, the expected population size after one year is, therefore, 450.
The expected population size after one year is 450
Data obtained from the question•Current population = 250
•Annual rate of increase = 0.8
•Expected population size =?
Determination of the expected increaseWe'll begin by calculating the expected increase in the pond. This can be obtained as follow:
•Current population = 250
•Rate of increase = 0.8
•Expected increase =?
Expected increase = Current population × rate
Expected increase = 250 × 0.8
Expected increase = 200
Determination of the Expected population size•Current population = 250
•Expected increase = 200
•Expected population size =?
Expected population size = Current population + Expected increase
Expected population size = 250 + 200
Expected population size = 450
Complete question:
A fish population of 250 in a pond has a maximum annual rate of increase of 0.8. If the carrying capacity of the pond is 1,500 for this species, what is the expected population size after one year?

What type of mutation causes a change in what amino acid the DNA strand
codes for?
Silent
Non Silent
Answers
Answer:
Non Silent
Explanation:
Mutation, is generally, any change or alteration to the genetic sequence of a DNA. However, mutation can be of different types depending on how it occurs. According to this question, a mutation is said to be SILENT if it involves the substitution of a nucleotide with another nucleotide that does not change the protein molecule encoded by the gene. In other words, the mutation happens in such a way that both the original sequence of gene and the mutated one codes for the same amino acid sequence (protein).
On the other hand, a mutation is NON SILENT i.e missense or nonsense mutations, if the mutation causes a change in what amino acid the DNA strand codes for. For example, in missense mutation, a different amino acid is produced while in nonsense mutation, a STOP codon is produced.

CUU are the nucleotides which transfer RNA carrying leucine. So, the correct option is (B).
What is RNA?RNA stands for Ribonucleic acids which is present in all living cells and have structure similarities to DNA.
It is a single stranded structure. It has a backbone made up of alternative phosphate group and the sugar ribose. Sugar is attached to one of the four bases. They are adenine (A), uracil (U), cytosine (C) or guanine (G).
There are three types of RNA which exist in cells messenger. They are messenger RNA (mRNA), ribosomal RNA (rRNA) and transfer RNA (tRNA).
1. Messenger RNA (mRNA) is translated into a polypeptide.
2. Transfer RNA (tRNA) will bind an amino acid to one end and has an anticodon on the other.
3. Ribosomal RNA (rRNA) helps facilitate the bonding of amino acids coded for by the mRNA.
Some of the RNAs are involved in gene expression regulation. As per the Central dogma of Molecular Biology, main role of RNA is to convert the information which is stored in DNA into proteins through the process called transcription.
Thus, CUU are the nucleotides which transfer RNA carrying leucine. So, the correct option is (B).

Meiosis is the process of cell division in which a single cell divides into four daughter cells. The genetic constitution of the daughter cells reduces to the half as compared with the parent cells. While crossing over, an exchanging of genetic material is passed between chromosomes and that allow variations to happen.
Describe an experiment you would perform to test a proposed chloroplast-targeting signal sequence. Be specific about the type of cell and the proteins you would use. Describe the results you would expect if the sequence is indeed a chloroplast-targeting signal.
Answers
Answer:
I would fuse the gene encoding the protein carrying the putative chloroplast-targeting signal sequence with the gene encoding Green Fluorescence protein. The GFP-tagged target protein enable to study the expression of the putative chloroplast localization signal sequence and its final cellular localization
Explanation:
The Green Fluorescence protein (GFP) is a protein widely used in molecular biology to investigate the expression of specific genes and then track the movement of proteins in living cells. This protein also can be used as a cell marker and to identify protein-protein interactions. When GFP is excited to a given wavelength (excitation peak 395 nm), it emits green light (emission peak 509 nm), thereby the expression/localization of the GFP-target fusion constructs can be evidenced by using a fluorescence microscope.

Which explanation describes why males are more likely to exhibit sex-linked disorders than females? Males have two X chromosomes that amplify all sex-linked disorders. Males have one X chromosome on which most sex-linked disorders are located. Males have only one functional sex chromosome on which all gender traits are located. Males have multiple sex chromosomes that mutate causing sex-linked disorders to become visible.
Answers
Answer:
males have one X chromosome
Explanation:
The explanation that describes why M are more likely to have linked disorders than W is that M have an X chromosome on which most linked disorders are located.
InheritanceLinked inheritance refers to genes located on chromosomes that are involved in trait determination.
In humans, the male chromosome Y has few genes. On the other hand, the female chromosome X has a large number of genes involved in the determination of various characteristics.
XY chromosomes have small homologous regions at their ends. Thus, there is practically no recombination between their genes.
When the altered gene is on the X chromosome. This type of inheritance has a recessive pattern.
It is the maternal inheritance. In this case, sons inherit X chromosome genes only from their mother. Meanwhile, F daughters inherit one from the father and one from the mother.
The manifestations will be present because they have only one X chromosome, that is, they do not have any normal gene for that characteristic.
With this information, we can conclude that the manifestations will be present in men, as they have only one X chromosome.

If a paramecium swims from a hypotonic to an isotonic environment, will its contractilevacuole become more active or less?
Answers
Answer:
Less.
Explanation:
Its contractile vacuole become less active because of the same concentration of water in both the body and outside environment. Contractile vacuole is responsible for the removal of excess liquid with the help of contraction. In isotonic environment, there is no flow water occur inside or outside of the cell due to the presence of equal amount water in both the environment i. e. cell and outside environment so due to equal amount of water, contractile vacuole become less active.
During which step of the cell cycle does a cell get a signal to begin cell division?
Answers
Answer:
Prophase
Explanation:
Prophase is not only the first step of Mitosis and Meiosis (I and II), but it is crucial because it helps the chromatin become chromosomes, this is after Interphase where DNA replication occurs this is the signal that starts the dividing process. This phase also helps with condensing the chromosomes which acts as another signal to division because the chromosomes are prepared to be separated from one another. Spindle fibers (microtubules) are also created to get ready for separation. Now that these main things happened during Prophase, it signifies the rest of the cell and the other phases occur.

Assuming you started with a saturated hemoglobin molecule, how many molecules of oxygen would need to be released in order for the hemoglobin to be 75% saturated
Answers
Answer:
only one oxygen molecule
Explanation:
Hemoglobin (Hb) is an iron-containing oxygen-transport protein localized in vertebrate red blood cells (i.e., erythrocytes). Moreover, the heme group is a component of the Hb protein which is capable of binding or releasing molecular oxygen. Hb consists of four globular protein subunits, and each subunit contains a heme group. This group (heme) binds to an oxygen molecule in a manner that each Hb protein can bind to four oxygen molecules in order to transport them throughout the bloodstream.
