pteropods or sea snails, also called sea angels, produce chemical deterrents to ward off predators, and some species of amphipods take advantage of this by carrying pteropods piggyback to gain protection from their voracious predators.
Why was progress in science interrupted during the dark ages? The Roman Empire fell in the 5th century thus advancements in science came to a halt. As science halted in Europe, where else did it advance? Science advanced in other areas of the world like China, Polynesia, and Arab nations.

What is a Objective Summary on Global Warming?
Answer:
Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.
Explanation:
Answer:
The study, published last month in the journal Geophysical Research Letters, found that climate change is making summers hotter and longer, while shrinking the three other seasons. ... They found that over the nearly 60-year period, summers grew from an average of 78 to 95 days long
In __________ ribosomes can attach to the mRNA and begin translation even though transcription has not been completed.
Answer:
prokaryotes
Explanation:
All cells translate using ribosomes. Prokaryotic DNA lacks a nucleus, therefore translation happens before transcription. Simultaneous transcription and translation takes place.
What is translation in prokaryotes?In all cells, translation takes place at ribosomes. Prokaryotes translate DNA before transcription is finished because their DNA is not bound by a nucleus. Both transcription and translation take place at once. When a start codon on mRNA attached to a small ribosomal subunit is recognized by an initiator tRNA anticodon, translation can start. A second tRNA is recruited as the big ribosomal subunit joins the tiny subunit.
This is not conceivable in eukaryotes because translation takes place in the cytoplasm outside of the nucleus, whilst transcription takes place in a membrane-bound nucleus.

What can you infer is the reason fruit flies are the most commonly used organism for this type of investigation
In the case of genetic investigation, scientists used fruit flies as their model organism since they share 75% of the genes that cause disease with humans. Fruit flies are also great to work in a research setting because they are relatively easy to take care of, especially compared to larger and more expensive organisms like rats or fish.Answer:

Which of the following correctly describes the two phases of the cell cycle?
A. Cells grow and develop during interphase. Cells reproduce during the mitotic phase.
B. Cells grow and develop during the mitotic phase. Cells reproduce during the interphase.
C. The nucleus of a cell divides during interphase. The cytoplasm of a cell divides during mitotic phase.
D. The nucleus of a cell divides during mitotic phase. The cytoplasm of a cell divides during interphase.
Answer: the answer is A
Explanation:
Cell cycle refers to the series of processes that leads to the growth/development and division of a cell. The cell cycle uses MITOSIS for cell growth. Mitosis comprises of two distinct stages namely: INTERPHASE AND MITOTIC PHASE. The interphase is referred to as the resting phase of the cell in which the cell grows and develops.
On the other hand, MITOTIC PHASE is the stage where the actual division of the nucleus (karyokinesis) and cytoplasm (cytokinesis) generally called CELL DIVISION occurs. Therefore, the cell reproduces i.e. one cell forming two, in the mitotic phase.

if you found a vertebrate skull in the woods and the teeth were sharp and scissor-like, what type of food would you expect this animal to eat?
Answer:
meat, or flesh.
Explanation:
sharp and scissor-like teeth are used to slice through bone and muscle, while flat-topped teeth are used for vegetables. this animal is a carnivore or an omnivore.
Sharp and scissor-like teeth are used to slice through bone and muscle, while flat-topped teeth are used for vegetables. This animal is a carnivore or an omnivore.
What are the characteristics of carnivores?A carnivore, or meat-eater, is an animal or plant whose food and energy requirements derive from animal tissues whether through hunting or scavenging.
Big carnivores include lions, tigers, and wolves. Some birds such as hawks and eagles are also carnivores. Snakes are usually carnivores as well. Small carnivores include frogs, birds such as robins, and spiders.
A carnivore is an organism that mostly eats meat, or the flesh of animals. Sometimes carnivores are called predators. Organisms that carnivores hunt are called prey.

Which statements correctly describe mutations in gametes and mutations in somatic cells?
Mutations to somatic cells are only present in the type of cell in which the mutation occurred.
Mutations to gametes are more likely to be beneficial than mutations to somatic cells.
Mutations to somatic cells will be inherited by an organism's offspring.
Mutations to gametes can be passed on to an organism's offspring
O Mutations to gametes do not involve changes in the DNA.
Mutations to somatic cells are transferred to daughter cells.
Answer:mutations to gametes can be passed on to an organism's offspring and mutations to somatic cells are only present in the type of cell in which the mutation occurred.
Explanation:The mutation in the somatic cells is known as somatic mutations. As they do not take place in the cells, which give rise to gametes, thus, the mutation is not inherited to the next generation by the sexual means.
On the other hand, the genetic mutations take place in the germline cells, that is, egg and sperm, because of this the mutations possesses the tendency to get passed on from one generation to another.
Thus, mutations are only passed on to offspring when they take place in germ cell DNA. The other kind of cells, the somatic cells refers to the rest of the cells in the body and mutations, which takes place in these cells do not get inherited further to the offspring.
Hence, the correct statements are
