Answer:
A
Explanation:
Next time give option so people could understand
The best description of fetal development is the heartbeats, which are heard during the first trimester. The correct option is A.
What is fetal development?It is the process by which an embryo develops and evolves into a fetus. Fetal development during pregnancy is a particularly delicate stage that is influenced by both maternal and environmental influences. The process by which a human fetus develops during pregnancy is known as prenatal development.
Most people find the beginning of a new life to be an exciting period, and this essay will examine the creation process. The things that could impair the prenatal growth of that new life, such as environmental factors, will also be covered.
Therefore, the correct option is A. The heart beats and is heard during the first trimester.

Answer: when the 6CO2 and the 6H2O in photosynthesis go in and they break up in to partials and they change and form in to 6O2 and C6H12O6, and then when the 6O2 and the C6H12O6 go in to cellular respiration and they do the same thing only 6CO2 and 6H2O comes out and the process start all over again.
Explanation:
Using relative dating, could a scientist determine whether C. amphibius or C. rapidus is older? Support your claim with scientific reasoning.
Answer:
Yes.
Explanation:
Yes, with relative dating, a scientist can determine whether C. amphibius or C. rapidus is older because relative dating provides information about the formation or presence of a material or organisms. Relative dating refers to the process of determining or finding if one rock or geologic event is occurring earlier or later than another or if one object such as rock or geologic event is older or younger than another. So by using relative dating we can find out which one is older, whether C. amphibius or C. rapidus.
Scientists can determine whether C. amphibius is older than C. rapidus, and vice versa, using relative dating.
We can arrive at this answer because:
Relative dating has the ability to place past events in a relative order, close to reality.This allows the age of a fossil, or an object, to be compared to the age of another object.In this case, the relative dating does not show the absolute age of the objects, but allows obtaining an approximate age, scientifically accepted and proven.This allows scientists to estimate which fossil is older than the other.

Assume you stain Bacillus by applying malachite green with heat and then counterstaining with safranin. Through the microscope, the green structures are Assume you stain Bacillus by applying malachite green with heat and then counterstaining with safranin. Through the microscope, the green structures are endospores. capsules. cell walls. flagella. The answer cannot be determined.
Answer:
The correct answer is:
endospores
Explanation:
endospores are spores formed by certain genera of bacteria eg, Bacillus. Spores generally are formed by the vegetative (growing) part of bacteria cells in response to adverse or unfavorable conditions. Spores are inactive and dehydrated and can stay dormant for a very long time, only germinating when the conditions are right. The outer covering of spores are made of tough protein coats, hence they do not take up conventional stains, but special staining methods like Malachite green can be used, and since the method makes use of heating, the primary stain (Malachite green) is forced into the tough coat of the spores (stains green), and resists the decolorization step, while the vegetative cells are easily decolorized, and take up the counterstain (Safranin), which stains the parent cells red.

Describe complementary base pairing between DNA with DNA and DNA with RNA
Answer:
Complementary base pairing between DNA and DNA consists of the way in which one DNA strand binds to another, by linking a pure base to a pyrimidine. Complementary base pairing between DNA and RNA occurs during transcription, where from the nitrogenous bases of the template strand, complementary nitrogenous bases are added to the RNA.Explanation:
The complementarity of nitrogenous bases consists of the union of a purine base and a pyrimidine base, allowing the bonding between two strands of a nucleic acid.
In DNA the purines are adenine (A) and guanine (G), while the primidines are cytosine (C) and thymine (T).
In RNA the purines are adenine and guanine, the pyrimidines being cytosine and uracil (U), since thymine is not found in RNA.
Adenine is complementary with thymine, or with uracil, forming a double hydrogen bond. Cytosine is complementary to guanine and forms a triple hydrogen bond.DNA with DNA DNA with RNA
A=T A=U
C≡G C≡G
Base pairing in DNA —DNA with DNA— is important in holding its two strands together, as well as in the replication process, which is carried out according to base complementarity.
DNA-RNA base pairing is observed during transcription where a purine base from the DNA template strand allows the incorporation of a pyrimidine into RNA, while a pyrimidine from DNA is complemented by a purine in RNA.

Are molecular or morphological data more useful when creating cladograms?
Answer:
Both of them are useful because it gives different information on the subject topic which could be an animal or a plant
Explanation:
Molecular data are data which arise from genetic compositions such as DNA and protein sequences while morphological data arise from the physical make up of an organism.
The molecular and morphological data are however equally important as they give sufficient information about a plant or animal in different and diverse ways
Morphological data is more useful when creating cladograms.
A cladogram is a diagram which shows the relationships among different species. It uses lines to show relationships and the bunch of lines attach to a single line known as a clade.
Are molecular or morphological data more useful when creating cladogramThe cladogram shows hypothetical relations among different species.The relationships are based on the physical characters of an animal.The diagram is made up of lines, and all the lines connect to common ancestry.Since cladogram diagrams are based on the physical or morphological characters of the organism. Therefore, The morphological data is more useful when creating cladograms.

What features evolved over time in the different animal phyla and classes? How did the features provide advantages that helped each group survive in their environment?
Answer:
What features evolved over time in the different animal phyla ? 5 Animals That Have Evolved Rapidly
Guppies Adapted to Predators. ...
Green Anole Lizards Adapted to an Invasive Species. ...
Salmon Adapted to Human Interference. ...
Bedbugs Adapted to Pesticides. ...
Owls Adapted to Warmer Winters.
How did the features provide advantages that helped each group survive in their environment?
Examples of the basic adaptations that help creatures survive:
shape of a bird's beak,
the number of fingers,
colour of the fur,
the thickness or thinness of the fur,
the shape of the nose or ears.
it produces variation in the offspring. the species can adapt to new environments due to variation, which gives them a survival advantage. a disease or change in environment is less likely to affect all the individuals in a population.
Animals develop a certain feature in their body, which denotes the natural selection condition which helps them for survivorship. For, example bedbugs adapted to pesticides
How evolution in animal phyla and classes helps with adaptation?There are several features developed in the animal phyla, which make the animals adapt to their changing environment over time.
Guppies adapted to predators, if any organism adapted to its predators, it can increase the population of that organism. The shape of the bird's beak helps them to catch the food which is necessary for its survival in that environment.
Therefore, this condition tells about natural selection, for the better survival of the organism, it may occur to change their body conditions and their behavior to adapt to that conditions.
