What do echinoid, snail, and shark tooth fossils have in common?
Answer: All have calcium made structures which restricts their degradation and decomposition.
Explanation:
Echinoids and snails have exoskeleton which is hard and made up of calcium carbonate which is the least degradable material even after death of the organisms and remains as traces and remains in the fossils. Also the shark tooth is made of dentin which is a hard calcified tissue which does not decompose very easily. It is denser and harder then the bones. It is surrounded by the enamel shell. The dentin and enamel prevent the degradation and decomposition of the shark tooth for long hence, it gets available as fossil.

Which behavior shows a way that animals defend their territory
Answer: Territorial behaviour, in zoology, the methods by which an animal, or group of animals, protects its territory from incursions by others of its species. Territorial boundaries may be marked by sounds such as bird song, or scents such as pheromones secreted by the skin glands of many mammals.
Explanation:
Answer:
Wolves work together to chase or kill any wolves that are not in
their group
Explanation:
Many animals rely on smells to mark their territories, spraying urine, leaving droppings or, rubbing scent glands around the territories' borders. Approaching animals will be warned off the territory without ever encountering the territory's defender.

Definition:-
“A cell is defined as the smallest, basic unit of life that is responsible for all of life’s processes.”[tex]\rightarrow[/tex] Cells are the structural, functional, and biological units of all living beings. A cell can replicate itself independently. Hence, they are known as the building blocks of life.
[tex]\rightarrow[/tex]Each cell contains a fluid called the cytoplasm, which is enclosed by a membrane. Also present in the cytoplasm are several biomolecules like proteins, nucleic acids and lipids.

Following are the various essential functions of cells:
Cells provide structure and support to the body of an organism.The cell interior is organised into different individual organelles surrounded by a separate membrane.The nucleus (major organelle) holds genetic information necessary for reproduction and cell growth.Every cell has one nucleus and membrane-bound organelles in the cytoplasm.Mitochondria, a double membrane-bound organelle is mainly responsible for the energy transactions vital for the survival of the cell.Lysosomes digest unwanted materials in the cell.______________________________

Which of the following is a critical factor driving evolution?
Environmental conditions
Health in comparison to similar organisms
Ability to acquire food
Strength in comparison to similar organisms
All of these are equally important
all of these are equally important, what if there is an option for natural selection, natural selection would be the most important but for this it's all these are equally important.
The critical factor driving evolution is strength in comparison to similar organisms.
According to Charles Darwin, Organisms that are better able to survive in their environment live long enough to reproduce and pass on these favorable traits to their offspring leading to the perpetuation of these organisms and gradual demise of other individuals of the same species who lack these favorable traits.
This is the origin of the cliché, "survival of the fittest". Hence organisms that lack certain strengths possessed by other organisms are gradually replaced by other individuals having such strengths.

Down syndrome in humans is due to ________ of the 21 st chromosome.
Answer:
Down syndrome in humans is due to ADDITIONAL, PARTIAL OR FULL COPY of the 21 st chromosome.
Explanation:
Down syndrome is a genetic disorder in which an individual has a total of 47 chromosomes instead of 46 that is, 23 pairs of chromosomes which is found in normal individuals. This occurs as a result of the presence of additional, partial or full copy of chromosome 21. There are generic variations that occurs in chromosome 21 leading to down syndrome, these include:
-->Trisomy 21 : the individual has three copies of chromosome 21 instead of two copies due to abnormal cell division that occurred during development of sperm or egg.
--> Mosaic Down syndrome: the individual has some cells with an extra copy of chromosome 21 and it's caused by abnormal cell division after fertilization.
--> Translocation down syndrome: This type of down syndrome occurs when chromosome 21 gets attached to another chromosome which occurs during or after conception.
Generally the symptoms due to the presence of this extra genetic material includes:
--> short heights
--> poor muscle development
--> short neck
--> short fingers with small hands and feet
--> increased risk to development of dementia
--> greater tendency to develop obesity

You are studying a plant whose seeds persist in the soil for a long time, normally only germinating when the seeds are brought to the surface in full sun by a disturbance such as a tree fall. However, in one of your experimental lineages you find that many seeds germinate when the surface is in full sun even if the seeds are buried too deep to grow to the surface before exhausting their reserves. You suspect that this lineage has a mutation that inhibits:
Answer:
The conversion of Pfr to Pr.
Explanation:
If the seeds germinates properly when the surface is in full sun and persist to germinate when buried deep into the soil, this shows that this lineage of seeds has a mutation that inhibits the conversion of Pfr to Pr
Why might more frequent prescribed burns be easier to control than less frequent burns?
Answer:
Wildfires that burn into areas where fuels have been reduced by prescribed burning cause less damage and are much easier to control. ... The time interval between fires can be as often as every year although a 3- or 4-year cycle is usually adequate after the initial fuel-reduction burn.
