Explanation:
Soil formation is influenced by organisms (such as plants), micro-organisms (such as bacteria or fungi), burrowing insects, animals and humans.
As soil forms, plants begin to grow in it. The plants mature, die and new ones take their place. Their leaves and roots are added to the soil. Animals eat plants and their wastes and eventually their bodies are added to the soil.
This begins to change the soil. Bacteria, fungi, worms and other burrowers break down plant litter and animal wastes and remains, to eventually become organic matter.
Design an experiment that determines the amount of time needed for a person’s heart rate to return to normal after exercise
Answer:
You could record yourself doing a cardio exercise such as running or using a jump rope for a certain period of time using a stop watch or a phone timer. Then stop after about 5-10 minutes and using the stop watch see how long it takes for your heart rate to go back to normal.
Explanation:
specificity of communication by the nervous system compared to the endocrine system
Answer:
Like the nervous system, the endocrine system is a regulatory system. However, instead of using electrical impulses for signaling, it produces and uses chemical signals called hormones, which travel through the bloodstream and control the actions of cells and organs.

why do you think diversity is important for the survival of a species?
Answer:
Genetic diversity refers to the amount of genetic variation within a species. Diversity is important for species survival as it provides a way for populations to adapt to changing environments with more variation. More individuals within a population will possess allele variations that are suited to the environment and they will survive more effectively.

The peppered moth is a classic example of natural selection in the
environment. The peppered moth has three color patterns: light, medium,
and dark. Prior to the industrial revolution, the light moth, which could
better blend with the tree bark, was the most prevalent. After
industrialization, the darker moth population quickly increased since the
tree bark became darker. Which of the following BEST describes why the
change in population occurred so quickly?*
Mutations took place in DNA.
O Different species of moths interbred.
Industrialization took place in a short period of time.
O Color variations were already present in living moths
Answer:
Color variations were already present in living moths.

Hi, I can help you!
Explanation:
There are more than 3,000 species of snakes on the planet and they’re found everywhere except in Antarctica, Iceland, Ireland, Greenland, and New Zealand. About 600 species are venomous, and only about 200—seven percent—are able to kill or significantly wound a human. Snake vision varies greatly between species. Some have keen eyesight and others are only able to distinguish light from dark, but the important trend is that a snake's visual perception is adequate enough to track movements. A young snake that is still growing may shed its skin up to four times a year, but an older snake may shed only once or twice a year.Snake venoms are complex mixtures of proteins, and are stored in venom glands at the back of the head.[
how does a tape worm feed
Answer:
The tapeworm feeds off the food that the host is digesting.
Explanation:
Tapeworms get into the body when a person eats or drinks something that's infected with a worm or its eggs. Once inside the body, the tapeworm head attaches to the inner wall of the intestines.
Answer:
Tapeworms do not have a digestive tract. Instead, they absorb their nutrients from the gut contents of the host directly through their outside surface, tegument. New proglottids are constantly formed in the neck of the worm and along the length of the tapeworm they mature.

The DNA code for normal hemoglobin contains the following segment:
TGC-GGA-CTC-CTC
Which of these is the m-RNA code for this segment of DNA?
A) UGC-GGA-CUC-CUC
B) ACG-CCU-GAG-GAG
ACG-CCT-GGA-GAA
D) TCC-GGT-CTC-CTC
The messenger RNA (mRNA) code for this segment of the hemoglobin DNA gene is ACG-CCU-GAG-GAG (Option B is correct).
What is mRNA?The messenger RNA (mRNA) is a template created during transcription, which is used to generate a protein.
A specific fragment of DNA is used to create this template (mRNA) by transcription.In RNA, Thymine nucleotide bases are replaced by Uracil nucleotide bases.In conclusion, the messenger RNA (mRNA) code for this segment of the hemoglobin DNA gene is ACG-CCU-GAG-GAG (Option B is correct).

Compared to a rounded particle with low density, a HIGH density,
rounded particle of the same size will sink through water
•more slowly
•at the same rate
•more rapidly
Answer:
more rapidly
Explanation:
Density of a substance refers to the mass of that substance in relation to one unit of its volume. The density of a substance is the basis of whether such substance will float or sink in a liquid. This means that if the density of an object is higher than that of a liquid medium e.g water, the object will SINK while if the density of the object is lower in relation to the liquid medium, the object will FLOAT.
According to this question involving a rounded particle. If the rounded particle is of low density than water, it will float. However, if the rounded particle of the same size is of HIGH density than water, it will SINK MORE RAPIDLY.

In base pairing for the translation of DNA to mRNA, which nitrogen base complements Adenine?
Answer:
Adenine and thymine form base pairs that are held together by two bonds, while cytosine and guanine form base pairs that are held together by three bonds. Bases that bond together are known as complementary. During transcription, DNA is converted to messenger RNA (mRNA) by an enzyme called RNA polymerase.

Answer:
A cell
Explanation:
Answer:
cell
Explanation:
The cell is the smallest structural and functional unit of living organisms, which can exist on its own. Therefore, it is sometimes called the building block of life. Some organisms, such as bacteria or yeast, are unicellular—consisting only of a single cell—while others, for instance, mammalians, are multicellular.
