How does evolution explain the similar legs in mammals and explain why the function differently?
Answers
Answer/Explanation:
These are examples of homologous structures. These are derived from common ancestors , however, they do not necessarily perform the same function. A good example is the vertebrate forelimbs like the ones shown here.
These limbs all have the same basic pattern of bones. They inherited this pattern from a common ancestor, but they now have different functions. This is an example of divergent evolution

a)Endoskeleton
b)Hydrostatic
C) Exoskeleton
Answers
Answer:
B) Hydostatic
Explanation:
Hydrostatic skeletons are found in invertebrate organisms, it means the skeleton is fluid filled, these are common in simple organisms. Endoskeletons are in vertebra animals, humans have an endoskeleton. Exoskeletons are in insects, which are invertebrates but the bone-like material is hard. I would chose Hydrostatic since it is filled with a liquid.

3. Why were germinating seeds used instead of dormant (non-

Answers
Answer:
An important function of seed dormancy is delayed germination, which allows dispersal and prevents simultaneous germination of all seeds. ... Many species of plants have seeds that delay germination for many months or years, and some seeds can remain in the soil seed bank for more than 50 years before germination.

gene is a segment of DNA on a chromosome. How are genes related to the proteins made by a cell?
Answers
Answer:
The DNA in genes is transcribed into RNA and translated into proteins
Explanation:
The sequence of DNA in a gene is transcribed into a messenger RNA (mRNA). This sequence of this mRNA is translated into a sequence of amino acids that form a protein.
The sequence of DNA in a gene directly affects the amino acids, and therefore the structure and function of, a protein.
Answer:
The structure of the genes in a cell determines the structure of the proteins made by the cell.

What are the solutions of the following equation?
Answers
Answer:
Explanation:
5 ( x + 3 ) - 4 = 8 ( x + 3 ) - 4
5x + 15 - 4 = 8x + 24 - 4
5x + 11 = 8x + 20
By substituting,
5x - 8x = 20 - 11
-3x = 9
x = -9 / 3
x = -3
So the correct option is D

4. There are very few producers that live deep below a lake's surface. Suggest an explanation for this patter.
5. Could producers survive without consumers? Why or why not?
Answers
Explanation:
Autotroph are known as producers
(2) Autotroph: An organism capable of synthesizing its own food from non-living substances using light or chemical energy.
(3) Consumer: An organism that eats other organisms
(4) Heterotroph: Organisms that obtain its food and energy by taking in living or once living material, usually plant or animal matter.
(5) Chemosynthesis: Process by which some organisms, such as certai (1) Producer: An organism that makes it's own food it is the first Link any food chain[ green plants]
(2) Autotroph: An organism capable of synthesizing its own food from non-living substances using light or chemical energy.
(3) Consumer: An organism that eats other organisms
(4) Heterotroph: Organisms that obtain its food and energy by taking in living or once living material, usually plant or animal matter.
(5) Chemosynthesis: Process by which some organisms, such as certain bacteria, use chemical energy to produce carbohydrates
(6) Photosynthesis: A process plants use to turn sunlight into food
How does the stability on an ecosystem depend on its producers?
they provide the basis for an ecosystems energy
What are the two processes used by producers to obtain energy?
photosynthesis and chemosynthesis
Few producers live deep below a lakes surface, suggest an explanation for this pattern
since sunlight is where most of the energy in an ecosystem comes from, there is less sunlight deep in a lake meaning less organisms can survive
Could producers survive without consumers?
without consumers, there would be too many producers and they would all compete with each other until they died out

Answers
Answer:
A mutation that changes the first letter to 'C' is called Frameshift mutation.
Explanation:
FRAMESHIFT MUTATION -: A frameshift mutation is a genetic mutation of a number of nucleotides caused by indels (insertions or deletions) in a DNA sequence that is not divisible by three. A frameshift mutation (also called a framing error or a reading frame shift) The addition or deletion may alter the reading frame (the grouping of codons) due to the triplet nature of gene expression by codons resulting in a completely different translation from the root. A frameshift mutation, instead of being added or removed, is not the same as a single-nucleotide polymorphism in which a nucleotide is substituted. In general, a frameshift mutation will cause the reading of the codons to code for various amino acids after the mutation. The first stop codon ("UAA", "UGA" or "UAG") encountered in the series would also change the frameshift mutation. The polypeptide that is formed will be abnormally short or abnormally long, and most likely will not be functional.Hence, the answer is Frameshift Mutation.Do you know what an orgasim is?

Answers
Answer:
The correct answer is c, plz give me brainlest
Explanation:
got 100 percent on the quiz
A property of argon that makes it useful for potassium-argon dating is that it decays into potassium. Thus, the correct option for this question is A.
What is Radioactive dating?Radioactive dating may be defined as a type of methodology for dating rocks and minerals with the help of radioactive isotopes. This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks.
Potassium-argon dating is a method of determining the time of origin of rocks by estimating the ratio of radioactive argon in order to radioactive potassium in the rock. This dating method is typically based on the decay of radioactive potassium-40 to radioactive argon-40 in minerals and rocks.
Therefore, a property of argon that makes it useful for potassium-argon dating is that it decays into potassium. Thus, the correct option for this question is A.

Fast moving mountain streams which flow over rocks and waterfalls are high in oxygen due to the amount of surface area of the water that is exposed to the air.
Fast moving mountain streams are high in nutrients. Organisms have adaptations to hold on in fast moving water, resulting in a large diversity organism.
Slow moving flood plain rivers are high in oxygen due to the amount of surface area of the water that is exposed to the air.

Answers
Answer:
B. 62, because this number will create a haploid cell, allowing both female and male gametes to be combined.
Explanation:
Sexual reproduction involves two organisms to come together (male and female). Sexually-reproducing organisms make use of a process called MEIOSIS to produce gametes or sex cells, which have a reduced number of chromosomes as the parent cells producing them.
A sexually reproducing organism must contain a complete diploid chromosome number (2n) that allows it to produce cells with a haploid chromosome number via meiosis. The haploid gamete cells that result from each meiotic divisions of male and female parents can combine to form a whole diploid organism.
The number of a species should be uses se-xual reproduction,
B. 62, because this number will create a haploid cell, allowing both female and male gametes to be combined.
Se-xual reproduction:It includes the two organisms for come together i.e. male and female. It make use of a process known as MEIOSIS to generate gametes. A se-xually reproducing organism should contain a complete diploid chromosome number (2n) that permits it to generate cells with a haploid chromosome number via meiosis.
