Explanation:
name one fossil anima
Answer:
Mold Fossils
Explanation:
Fossils of the same type and same age have been found on different continents. If we were to put South America and Africa together, these fossils would even be in the same area! What does this tell us? How could this happen?
Can some one help me plz
Answer:
there have been several cases where fossils of the same type and age where found on different continents.
For example:-
"The Mesosaurus" which is an extinct genus of reptile from the Early Permian and was found in the continents of southern Africa and South America.
This seems to point to the fact that once all the continents were togethe, and they are now separate due to the Continental drift. ( the theory that states that all the continents were earlier one big form of landmass, but they have moved away from each other thus appearing to have "drifted" across the ocean bed."
But again these are all just theories and speculations but findings like these strengthen them and make people believe in these theories. They haven't exactly been confirmed. Like the evolution theory.
i hope this helps.
have a great day ahead :)
Blood is a critical body fluid. What role does blood play in the body? How is it usually cleaned, and how is it cleaned during dialysis?
Answer: Dialysis cleans your blood by passing it through a filter. If you do peritoneal dialysis (PD), the filter is the lining of your abdomen (your peritoneum). If you do hemodialysis, the filter is made of plastic. Your blood is on one side of the filter.
Explanation:Hemodialysis uses a machine to pull blood out of the body, filter it, and pump the clean blood back into the body again. The actual filtering happens in a part of the machine called a dialyzer, or artificial kidney. The dialyzer has two parts. One part is for blood.

with reference to evolution of long neck in giraffe explain how natural selection brings about adaptation of species to its environment
Answer:
Explanation:
In order to reach specific items of food that meet the dietary needs of the giraffe, they must reach for food up in the trees. Giraffes with longer necks are open to a wider array of food whereas the short necked giraffes are limited. The longer neck is seen to be more favorable. When a trait is more favorable, it has a higher likelihood of being passed on. The less favorable traits are eliminated or "weed" out and the taller giraffes mate with other tall giraffes, generating a greater population with this trait. Again, it is solely dependent on what is available around them and their surroundings.

which organisms are necessary for the recycling of nitrogen
Answer:
Explanation:
It is carried out by nitrogen-fixing bacteria. The bacteria live in soil and roots of legumes, such as peas. When plants and other organisms die, decomposers break down their remains. In the process, they release nitrogen in the form of ammonium ions.
how Is the energy for an earthquake generated?
a. Make a list of as many traits as you can think of that could be used to classify a new species.
b. Which of the traits in the list above would be most useful for classification at high levels (e.g. classifying things into different kingdoms or phyla) , which would be more helpful at lower levels (e.g. family or genus)
Answer:
a. My list is the following:
1. presence of photosynthetic pigments
2. presence of cell wall
3. body symmetry pattern
4. presence of cell nucleus
5. presence of specialized organelles
6. presence of hair
7. presence of mammal glands
8. niche (e.g., terrestrial or marine habitats)
9. diet (food habits)
10. position of a particular muscle
Explanation:
b. In the list above, traits such as the presence of a cell nucleus or specialized organelles can be used to classify organisms at the kingdom level (since these phenotypic features are observed in eukaryotic organisms but not in prokaryotes). In a similar mode, animals may exhibit two different body symmetry patterns: radial (around the central axis) and bilateral (two sides: left and right), thereby symmetry body can be used to classify organisms within the animal kingdom. Other features used to classify species at high levels include the presence of photosynthetic pigments in green plants (chlorophyll) and bacteria (xanthophyll), presence of cell walls in plants (composed of cellulose,) and fungi (composed of chitin), presence of hair and mammal glands (mammals), etc. On the other hand, ecological differences (e.g., food habits, niche) and minor anatomical differences (e.g., the position of a particular muscle) are helpful to classify species at the family/genus level.

Determine the parental genotypes and proportion of offspring genotypes for locus 2. What are the genotypes of the parents with respect to locus 2 (i.e., alleles B and b)
Answer and Explanation:
Alleles are the different varieties of genes. For every gene, somatic cells have two alleles.An allele that is not expressed by an organism might be passed to the offspring of The organism provides one allele.
It is difficult to conclude which two alleles of a gene exist within the chromosomes of organisms. that organism and can express in the next generation.
The parental genotypes can be determined by PUNNETT SQUARE, in which we use two letters to signify the genotype.
As the white throat code and the red throat code are alleles.
A lowercase letter represents the recessive form of a gene (allele), and a capital letter represents the dominant form of a gene (allele). For example, for the red-throated bird, white throat is a recessive trait, and red throat is a dominant trait.
There are basic steps of using Punnett Square. Step one is to determine the parent organism genotypes then write down “mating.” Draw a p- square. For each parent, split the letters of the genotype. Then place them outside the p-square. By filling the p-square, determine the genotype of the offspring. Then summarize results.

Glycolysis is an aerobic process. *
True
False
Answer:
False
Explanation:
Glycolysis is an anaerobic process. None of its nine steps involve the use of oxygen. However, immediately upon finishing glycolysis, the cell must continue respiration in either an aerobic or anaerobic direction; this choice is made based on the circumstances of the particular cell.

Lexie lives at sea level, but her family rented a vacation cabin high in the Rocky Mountains for two weeks. She noticed a difference in her breathing.
An image of a mountain with three circles going up the side of it. The lowest circle is filled with many, smaller circles. The middle circle has fewer circles that are farther apart. The highest circle has the fewest circles that are the farthest apart.
What do the molecules in the circles model regarding altitude?
A. Air pressure increases at higher altitudes.
B. Air density decreases at higher altitudes.
C. There is a greater gravitational pull on air molecules at higher altitudes.
D. Temperature has a decreasing effect on air molecules at higher altitudes.
Answer:
B. Air density decreases at higher altitudes
Explanation:
Since air is compressible, air from higher altitudes will compress air from lower altitudes. As a result, air density at lower altitudes will be greater than air density at higher altitudes. Air particles at the highest altitudes, not being acted upon by air above it, will be more spread out.
Grandma Hippity Hop is worried about the ice that will be forming on her sidewalk this winter. She doesn't have money to waste on sidewalk salt that is ineffective, so Brenda decides to do some testing for her.
Indepedent Variable - ______________________________________________________
Dependent Variable - _______________________________________________________
Controlled Variables: (There are at least 5. Please list 2) __________________________________________________________________________________
__________________________________________________________________________________
Answer:
Independent variable- SIDEWALK SALT
Dependent variable- ICE FORMATION
Controlled variables- same size of ice, same sidewalk
Explanation:
Based on the information given in this question, Brenda is helping Grandma Hippity Hop test the effect of sidewalk salt on the formation of ice on her sidewalk.
In an experiment, the independent variable is the variable that is changed or manipulated by the experimenter. In this case, the SIDEWALK SALT is the independent variable because it is the one being changed i.e used or not used.
Dependent variable is the variable that responds to the changes made to the independent variable. It is the variable that is measured or recorded in an experiment. In this case, the ICE is the dependent variable because its formation is dependent on the SALT (independent variable).
Controlled variable or constants are variables of an experiment that are kept unchanged throughout the experiment. In this case, the SAME SIDEWALK AND SIZE OF ICE are used, hence, they are the controlled variables.
Giraffes get their long necks from stretching for food- an idea discovered by Lamarck
True
False
Answer:
False kind sir/mam
Explanation:
Answer:
The answer is false
Explanation:
The French zoologist Jean-Baptiste Lamarck is usually credited as the first person to suggest that long necks have evolved in giraffes because they allow them to get to the parts other herbivores cannot reach.

Within a plant, photosynthesis is critical. It provides cells with the glucose they need for
energy. Photosynthesis is important for another reason, too. It's part of the flow of carbon
through organisms and the environment. This cycle, known as the carbon cycle, is essential
for life on Earth. It includes several processes that are occurring all the time. When plants
photosynthesize, carbon is removed from the atmosphere as carbon dioxide. When animals
and plants use cellular respiration, carbon is released into the atmosphere as carbon
dioxide. Organisms that die and are buried for millions of years turn into fossil fuels, which
are made of carbon. When humans burn those fossil fuels, carbon is released into the
atmosphere as carbon dioxide. Without enough carbon dioxide in the atmosphere, the
planet would be too cold. But too much carbon dioxide contributes to the warming of the
planet that could make it too hot to survive.
Based on the passage, what is one reason that the carbon cycle important?
A It adds carbon into the atmosphere whenever the level begins to drop too low.
B
It helps maintain a level of carbon in the atmosphere that is neither too hot nor
too cold.
с
It removes carbon from the atmosphere whenever the level begins to become
too high.
D
It releases carbon into space, preventing it from building up in Earth's
atmosphere.

B

A student wants to know which part of his local beach contains the most turtle nests during nesting season. He makes a prediction to investigate based on his observations and plans his experiment. He performs the experiment to collect data. Once his experiment is completed, he gathers his evidence and analyzes it to form a conclusion. What part of the scientific method is he missing from this investigation? Ask a question. Construct a hypothesis. Do background research. Analyze the evidence.
Answer:
Construct a hypothesis
Explanation:
The scientific method is a step by step procedure followed in order to solve a scientific problem or answer a scientific question. The steps of the scientific method include:
- Making an observation
- Asking a question
- Doing background research
- Formulating an hypothesis
- Testing the hypothesis
- Analysing the result
- Conclusion
Based on the steps above, the student performing the investigation did not do a CONSTRUCT A HYPOTHESIS based on the prior information he/she has. Hypothesis is a testable explanation to a given problem or an asked question. The student failed to CONSTRUCT THE HYPOTHESIS, which is necessary to know whether or not to accept the results obtained.

MASTERY CONNECT MITOSIS
Answer:
According to the cell cycle data provided in the table, these data indicate that cells spend most of their time preparing for the cell cycle (third option).
Explanation:
The cell cycle is divided into two major phases, interphase —without cell division— and cell division or mitosis. Interphase in turn is divided into three phases prior to the division process:
G1 phaseS phaseG2 phaseAssuming that the complete cell cycle lasts 24 hours, the cell will remain in interphase for 23 hours - preparing for the next division - investing only 1 hour in cell division or mitosis.
The data provided by the table indicate that, at a given time, there will be a greater number of cells in the interphase stages, indicating that cells spend most of their time preparing for the cell cycle.

The epicenter of an earthquake is the area where the least amount of damage takes place.
Answer:
Yes it can be.
Explanation:
Surface damage. The epicenter is directly above the earthquake's hypocenter (also called the focus). In most earthquakes, the epicenter is the point where the greatest damage takes place, but the length of the subsurface fault rupture may indeed be a long one, and damage can be spread on the surface across the entire rupture zone.
