Answer:
the first and fourth questions are nonscientific, the rest are.
Explanation:
Does my dog like me?" - Nonscientific. Are bats blind? - Scientific. What do fish eat? - Scientific. Do unicorns really exist? - Nonscientific. Can bees communicate by doing a special dance? - Scientific.
The answers to whether each question is scientific or nonscientific are as follows:
1. ""Does my dog like me?"" - Nonscientific. This question is about a subjective experience and personal feelings, which cannot be empirically tested or observed.
2. ""Are bats blind?"" - Scientific. This question can be answered through biological research and empirical observation. Bats are not blind; many species use echolocation to navigate and can see.
3. ""What do fish eat?"" - Scientific. This question can be answered through biological and ecological research. Different species of fish have different diets that can be studied and documented.
4. ""Do unicorns really exist?"" - Nonscientific. Unicorns are mythical creatures, and their existence cannot be tested or observed in the natural world.
5. ""Can bees communicate by doing a special dance?"" - Scientific. This question can be answered through entomological research. It is well-documented that bees, particularly honeybees, perform a waggle dance to communicate the location of food sources to other members of their hive.
Scientific questions are those that can be answered through empirical research, observation, and experimentation. They are based on phenomena that can be measured and tested. Nonscientific questions, on the other hand, often involve subjective experiences, personal beliefs, or hypothetical entities that cannot be empirically tested or observed.

How does global warming lead to climate change?
Answer:
global warming leads to climate change as global warming is caused by carbon dioxide trapped in the earth's atmosphere. sunlight can get trapped in the atmosphere as there is a high concentration of CO 2 so the sunlight hits the CO 2 and it bounces back to earth and because the CO 2 is covering the atmospehere it will keep on reflecting and that heats up the air causing water to evaporate and the climate to change

A scientist injected a drug into a mouse that inhibits the formation of mRNA in either the sperm or egg cells.
What could be the result of this alteration?
Answer:
The mouse will not be able to form sperm or egg or abnormal sperms or egg will be formed.
Explanation:
For the synthesis of proteins, the DNA is transcribed and an mRNA is formed. This mRNA is translated by the ribosomes and a protein is formed. If mRNA is not formed, then the protein will not be able to form.
If the formation of mRNA is inhibited for the sperm or egg cells they will either not form the right kind of sperm or egg cells or will not produce them at all depending on the mRNA that is being inhibited from the formation.
Refer to figure 10.13. Which photos (A-I) best illustrate the methods of fossilization or fossil evidence listed below
Answer:
Permineralization:
A. Trilobite fossil
F. Trilobite fossil
B. Fossilized wood
Cast:
G. Fossil dung
Carbonization:
C. Fossil bee
I. Fossil fish
Impression:
D. Fossil brachiopods
Amber:
H. Fossil spider
Indirect impression:
E. Dinosaur track
G. Fossil dung
Explanation:
Permineralization:
The most common process of fossilization in which the remains of the organism, particularly, the internal cavities are replaced by the deposition of minerals carried by water or sediment.
Cast:
Casts are formed when the actual remains and bones of the organism are dissolved, creating a depression or a mould that gradually fills with sediments to form a cast of the exact shape of the original.
Carbonization:
The fossilization process in which only the residual carbon of the living organism remains leaving behind a thin carbon layer.
Impression:
Fossilization that involves the preservation of the prints or impressions of animals and plants when the print is made in silt or mud. This mud or silt hardens to rock.
Amber:
Amber is living organism preserved in fossilized tree resin.
Indirect Impression:
Indirect impressions are two dimensional imprints that do not contain any organic material from the organism itself but give a clue of its existence and biological activity. Footprints, tracks and excrement is fossilized in this manner.
The question focuses on matching photos to different methods of fossilization, requiring reference to textbook figures and flowcharts. The answer would involve examining photo characteristics and comparing them with textbook descriptions of fossil preservation processes.
Explanation:The student's question pertains to identifying methods of fossilization and analyzing fossil evidence, based on images from a textbook. The question requires matching specific photos illustrating different fossilization processes to a list of such methods. To address such a question, one would typically refer to the figures provided in the textbook, which likely include visual examples of petrification, mold and cast fossils, amber preservation, permineralization, and other types of fossil evidence. Utilizing the flowcharts and exercises mentioned, such as Figure 6.10 and Exercise 6.2, would aid in understanding the mode of preservation. Additionally, figures showing the evolutionary progression of species through fossil records, such as whales and horses, provide context for understanding the diversity and history of life on Earth as evidenced by fossils.
When helping a student with this type of inquiry, a tutor would guide them to look at the characteristics of each photo, such as whether there is presence of original biologic material, positive and negative relief, and mineral composition, and compare these with the types of fossilization processes described in the textbook. Being able to identify such features enables one to determine fossil evidence and likely methods of fossilization. Critical thinking may also be applied in assessing whether certain fossils suggest organisms are now extinct, by identifying unique features not found in modern-day species.

How do scientists construct recombinant DNA molecules?
by using RNA from plants
by combining the proteins from two different organisms
by combining the DNA of two different organisms
by combining the RNA of two different organisms
Answer:
by combining the DNA of two different organisms
Explanation:
Recombinant DNA is when researchers edit a gene to contain a novel sequence, such as one from another organism
A good example of this in the lab is when scientists combine genes with a fluorescent gene called green fluorescent protein, GFP. This is from jellyfish. The gene sequence can be tracked on to the end of a gene of interest in a cell population or organism. When the gene is transcribed and translated, the GFP sequence will also be transcribed and translated. This means it will be fluorescent green and easy to track and visualise in cells.

The composition of the sun is best described as-
Final answer:
Hydrogen and helium constitute 98% of the Sun's mass, and the Sun is predominantly a hot ionized gas called plasma, structured in layers such as core, radiative and convective zones, and various atmospheric levels.
Explanation:
The composition of the Sun is best described by its major constituents: hydrogen (about 74% by mass) and helium (about 24% by mass), which together make up 98% of the Sun's mass. The rest is a mixture of heavier elements such as oxygen, silicon, and aluminum. The Sun's structure includes several layers: the core, where nuclear fusion occurs, the radiative zone, the convective zone, and several layers of the solar atmosphere, namely the photosphere, chromosphere, transition region, and corona. Additionally, the Sun is predominantly composed of ionized gas known as plasma, with a consistent bubbling and changing surface, featuring phenomena like sunspots, solar flares, and prominences that can impact Earth.

What do the c cells of a thyroid gland produce
Calcitonin is a hormone produced by the c cells of the Thyroid gland.
Explanation:
The c cells present in the thyroid are otherwise called Parafollicular cells. The primary function of c cells is to secrete Calcitonin (a protein hormone) which has a minor role in calcium regulation.Calcitonin decreases the parathyroid hormone (PTH), by lowering blood calcium level by suppressing osteoclast activity of bones and increases of calcium Which is excreted along with the urine.The C cells are found next to the Thyroid follicles and present in the connective tissue.
The C cells or parafollicular cells of the thyroid gland produce a hormone known as calcitonin, which plays a crucial role in the regulation of calcium levels in the body.
Explanation:
The C cells, also known as parafollicular cells, of the thyroid gland produce a hormone known as calcitonin. Calcitonin is an important hormone for the regulation of calcium levels in the human body. It works in tandem with the parathyroid hormone to decrease high calcium levels in the blood. When the blood calcium level is high, calcitonin is secreted. This hormone then stimulates the transfer of calcium from the blood into the bones, thus reducing the calcium level in the blood.

Organisms in the deepest part of the ocean (the abyssal zone):
A: come up to the surface often to breath
B: do you not need oxygen
C: feed only on minerals
D: Live without any sunlight
Answer:
Option A.
Organisms in the deepest part of the ocean come up to the surface to breath.
Explanation:
Abyssal zone is the part of the ocean towards the bottom. It consists of 83% of the ocean. The zone is completely dark. There is no sunlight striking this zone so the organisms which require sunlight are not found here. The organisms like sharks and deep sea fish in this zone have to reach above them for breathing dissolved oxygen as this zone has no such plants to produce oxygen.Which statement describes absolute and apparent brightness?

There are 2 atoms of mercury in the reactant side and the product side.
There are two atoms of the element oxygen at the reactant side, the product side also has two atoms of oxygen. Hence, this reaction is properly balanced.
How would scientists determine that punctuated equilibrium occurred by examining the fossil record?
Scientists cannot tell if punctuated equilibrium occurred by looking at the
fossil record
Scientists can tell that punctuated equilibrium occurred when they see a
gradual change in organisms in the fossil record
Scientists would have to have the fossils of all organisms in a certain
species to be able to tell if punctuated equilibrium occurred.
Scientists can tell that punctuated equilibrium occurred if they examine
the fossil record and see that one organism rapidly evolved different
characteristics
Answer:
The answer is: Scientists can tell that punctuated equilibrium occurred if they examine the fossil record and see that one organism rapidly evolved different characteristics.
Explanation:
The theory regarding "punctuated equilibrium" followed after Darwin's Theory of Evolution. According to Darwin, species evolved over time. However, evidence supporting it is lacking when it comes to fossil record. He thought that this was because the fossils were incomplete.
Darwin's idea was contradicted by evolutionary scientists, named Stephen Gould and Niles Eldrege. According to them, species change after millions of years (this phase is called "punctuated") and their change is sudden (and not gradual). This sudden change is very rapid, thus causing a fewer number of fossils being left behind. Most species who undergo speciation, occur in a different geographic location, thus leaving only a few number of fossils.
So, this explains the answer.
