Answer:Where Translation Occurs. Within all cells, the translation machinery resides within a specialized organelle called the ribosome. In eukaryotes, mature mRNA molecules must leave the nucleus and travel to the cytoplasm, where the ribosomes are located.
Explanation:
Here, we are required to determine which main organelle is involved in translation in eukaryotic cell.
The organelles which are involved in translation in eukaryotic cells are the Ribosomes.Translation in eukaryotic cells is a biological process characterized by the translation of messenger RNA into proteins in eukaryotes.
This translation process is brought about by a sequence of processes as follows;
gene regulation, elongation, termination, and recycling.The cytoplasm where the ribosomes are located happens to be the site for translation in eukaryotic cell.
The Ribosomes which are the organelles that are responsible for translation are made of a small and large subunit which surrounds the mRNA.
More specifically, In eukaryotic cells translation, 80S ribosomes with 40S and 60S subunits are used.

Why are girls more likely than boys to be victims of cyberbullying
Girls are more verbal than boys and more likely to use words to hurt than fists. Previous studies have found that girls are more likely to cyberbully than boys while boys are more likely to be physical. When you look at overall bullying, girls are still significantly higher than boys (but most of that increase comes from the online or by text).

Taxol is a drug that comes from the bark of a tree that binds and irreversibly stabilizes microtubules. It is often used during chemotherapy to kill dividing cancer cells. How does taxol block cell division?
A-
Taxol prevents the contractile ring from forming and dividing the cell in two.
B-
Taxol prevents DNA replication.
C-
Taxol prevents chromosome condensation during prophase.
D-
Taxol prevents spindle formation and separation of chromatids.
Answer: D-
Taxol prevents spindle formation and separation of chromatids.
Explanation:
The Taxol is used as an anticancer drug formulation. It is obtained from yew tree. An anticancer drug affects the cell cycle machinery so as to limit the production of cancer cells. This drug ceases the microtube formation in animal cells. This prevents the spindle fiber formation and further prevents the mitosis of cancerous cancers as the chromosomes will not separate apart and so abnormal cells will not produce further.
Dogs have 39 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere. Once the chromosome has split, each chromatid is called a daughter chromosome. At the end of cytokinesis, how many daughter chromosomes will be found in each dog cell?
Answer:
39 daughter chromosomes
Explanation:
This question is describing the MITOTIC process, which involves the synthesis of two daughter cells from one parent cell. In mitosis, sister chromatids, which forms a chromosome, separates at their centromere to become individual chromosomes in their respective daughter cells.
N.B: Mitosis produces two daughter cells which are identical in chromosome number.
In this case, a dog is said to have 39 chromosomes in its diploid cell. Since two chromatids make up one chromosome, 78 chromatids will be found in the dog cell. The 78 sister chromatids that form 39 chromosomes will each separate at their centromere to form 39 daughter chromosomes in each daughter dog cell.

PLEASE HELP!!! A scientist concludes that genetic inheritance of a mutated (changed) gene, such as a gene change that creates different-colored organisms in a population, is more beneficial to an organism over time and contributes to biological fitness. Discuss why a scientist would make that claim.
i posted a few min. ago and someone stole 30 points by answering and saying they couldnt help. please answer the question if you can and dont steal my points....
Answer:
When the organism inherits a mutated gene creating new colored organisms into the population, this can increase diversity. As more organisms inherit the same mutation, the population will become more variated, which can increase the organisms abilities to survive and adapt in a changing environment, and also improve the biological fitness of individuals; resulting in allowing more organisms to reproduce successfully.

you know tadpoles undergo metamorphosis to become adult frogs, and you suspect the mortality rate is high for tadpoles during this transition. How would you determine the number of tadpoles that survived to become adults
Answer:
by counting the number of tadpoles and adult animals 2 weeks post-metamorphosis
Explanation:
During its growth, the tadpole turns into a frog by a complex biological process known as metamorphosis, producing an adult land animal with 4 legs to move and lungs to breathe. During this process, tadpoles face different threats such as, for example, predators (i.e., turtles, birds, fish), diseases that spread quickly through natural populations, limited food, etc. In natural environments, it is possible to determine the mortality rate during metamorphosis by calculating the number of tadpoles and then by comparing it with the number of adult individuals (i.e., post-metamorphosis). Moreover, it is also possible to determine the causes of death by placing fresh tadpoles in experimental optimal conditions and then by comparing both mortality rates. Another mode to determine the causes of death is the examination of these dead animals by a wildlife pathologist.

Which of the following statements best describes the role of adenylyl cyclase in the epinephrine signaling pathway?
Group of answer choices
It converts a polymer to its monomer subunits.
It moves substances across the plasma membrane.
It accelerates the production of a second messenger.
It transfers phosphate groups from to protein substrates.
Answer:
It accelerates the production of a second messenger.
Explanation:
Adenylyl cyclase is an enzyme capable of converting ATP molecules into cyclic adenosine monophosphate AMP (cAMP). The cAMP molecule is considered to be a second messenger that transfers the hormonal signal (i.e., epinephrine) inside the cell. Subsequently, cAMP activates molecular signaling events by binding and thus activating cAMP-dependent protein kinase A (PKA). Finally, this last protein (PKA) phosphorylates different proteins that control many diverse cellular processes.

What is the growth rate for a country that
has 84,000 births and 55,000 deaths per year
along with 24,000 people who immigrate in
and 5,000 people who emigrate out? The
total population is 23,000,000.
Answer:
The country has an annual growth rate of 0.2%.
Explanation:
If the country has 84,000 births and 55,000 deaths per year, as well as 24,000 people who immigrate to the country and 5,000 people who migrate abroad, the gross annual population growth is 48,000 people (84,000 - 55,000 + 24,000 - 5,000).
Now, to determine what percentage this growth implies, the following cross-calculation must be performed:
23,000,000 = 100
48,000 = X
((48,000 x 100) / 23,000,000) = X
0.2 = X
Thus, the country has an annual growth rate of 0.2%.
