Answer:
The Eyebrows
Explanation:
The eyebrows are not just those short hairs that humans can use to make signals for non-verbal communication with other humans, they, as one of the accessory structures of the eye, protect the eyes from perspiration (sweats) dripping down the forehead, or water running down from the head from entering the eyes, causing irritation. They also help shade the eyes from the high impact of the sunlight and help keep dirt away too.

Based on the the table of rock characteristics and your knowledge of the rock cycle, in which type of
rock (igneous, metamorphic, or sedimentary) would you expect to find bubbles or a smooth, glassy
surface? Why?
HELPPPP ASAP
Answer:
The answer would be igneous. But there are two types of igneous rocks. One is Intrusive, or Plutonic, rocks, and the other is Extrusive. Intrusive rocks crystallize from magma beneath the earth's surface. Extrusive or volcanic rocks crystallize from lava at the earth's surface. Either way, Igneous would have a bubbly, or a smooth, glassy surface.

Using the allele symbols in the table, identify the genotype of a guinea pig that is recessive for hair length, heterozygous for hair color, and homzygous dominant for hair texture.
Answer:
Hair length: hh
Hair color: Bb
Hair Texture: RR
Explanation:
In order for the recessive gene to show for hair length, two of the same alleles must be present, so, in this case, hh.
The question states "heterozygous for hair color." This tells you that the genotype will be Bb. Heterozygous means two of the different alleles. This is different from homzygous.
The question states "homzygous dominant for hair texture." This tells you that it will contain two of the same alleles. The question also tells you that it is homzygous dominant, which means there will be two of the same dominant alleles, so, RR.

Speculate on how an increase of carbon dioxide and a decrease of oxygen might affect the pond ecosystem.
Answer:
There will be a reduction in the number of species in the pond
Explanation:
Oxygen is a very pivotal substance needed for the growth and metabolism of living organisms as it is a requirement for the process of cellular respiration that generates energy in cells.
If oxygen begins to reduce, there will also be a reduction in the number of organisms in the pond ecosystem because every cell undergoes cellular respiration.

A savannah ecosystem includes grasses, zebras, and lions, and elephants.
Which of the following has the greatest overall biomass in this ecosystem?
grasses
lions
zebras
elephants
Answer:
Add native plants to a suburban garden because you are adding already flourishing wildlife
Sea Urchins are primary consumers because they eat the kelp
Sun -> Grass -> Rabbit because grass lives off of photosynthesis from the sun and rabbit eats the grass
I think there would be more biomass in grass because there is a lot more spread throughout the savannah while elephants are way bigger there is less of them.
Name the two types of leucocytes that are phagocytic.
NO SPAM PLS ...
Answer:
In humans, and in vertebrates generally, the most-effective phagocytic cells are two kinds of white blood cells: the macrophages (large phagocytic cells) and the neutrophils (a type of granulocyte).
In the blood, two types of white blood cells, neutrophilic leukocytes (microphages) and monocytes (macrophages), are phagocytic. Neutrophils are small, granular leukocytes that quickly appear at the site of a wound and ingest bacteria.

What is the positive aspect of GMO
The pros of GMO crops are that they may contain more nutrients, are grown with fewer pesticides, and are usually cheaper than their non-GMO counterparts. The cons of GMO foods are that they may cause allergic reactions because of their altered DNA and they may increase antibiotic resistance.
Today, those who directly see the most benefits from GMOs are farmers and agricultural companies. ... GMOs are also used to produce many medicines and vaccines that help treat or prevent diseases. Before GMOs, many common medicines had to be extracted from blood donors, animal parts, or even cadavers.

Explanation:
There are multiple positive aspects of GMO, but it has many drawbacks as well. Genetically modified foods can become more resistant to disease, pests, and even natural disasters(floods, drought, etc.)

Choices: bronchi, nasal cavity, capillaries, trachea, pharynx, aveoli, bronchioles
Answer:
Nasal Cavity, Pharynx, Trachea, Bronchi, Bronchioles, Alveoli and Capillaries.
Explanation:
We first breathe in the air through our nose so it goes through our nasal cavity. After that it goes down our throat past the pharynx (voice box) and through the trachea (windpipe). From here it arrives in our lungs via the bronchi, which then splits into smaller bronchioles which have alveoli at the end of them. The alveoli then have small capillaries which the oxygen goes into so it can travel around the body through the bloodstream.

Both groups should have been tested in the same soil type at each humidity level.
The percentage of humidity should have been kept constant
Fewer plants should have been included in each group
Another plant species should have been tested
Answer:
Both groups should have been tested in the same soil type at each humidity level.
Explanation:
From the experimental process described above, the student failed to control for bias which could creep in by not controlling for the soil type used, controlling for possible error as a result of the soil type requires that each group is tested using the same soil type, this way, the student can be confident that variation in the result is not due to the non-uniformity in soil type the plants were subjected to. At each humidity level, the groups should be tested using the same soil type. This way, observed result would have been largely due to different humidity levels.
Explain the structure of ribosomes and describe what they do. Then, discuss how ribosomes are different from other organelles.
Explanation:
A ribosome is a complex molecular machine found inside the living cells that produce proteins from amino acids during the process called protein synthesis or translation. The process of protein synthesis is a primary function, which is performed by all living cells.
Ribosomes are specialized cell organelles and found in both prokaryotic and eukaryotic cells. Every living cell requires ribosomes for the production of proteins.
This cell organelle also functions by binding to a messenger ribonucleic acid (mRNA) and decoding the information carried by the nucleotide sequence of the mRNA. The transfer RNAs (tRNAs) comprising amino acids, enter into the ribosome at the acceptor site. Once it gets bind up, it adds amino acid to the growing protein chain on tRNA
A ribosome is a complex of RNA and protein and is, therefore, known as a ribonucleoprotein. It is composed of two subunits – smaller and larger.
The smaller subunit, where the mRNA binds and is decoded and in the larger subunit, the amino acids get added. Both of the subunits contain both protein and ribonucleic acid components.
The two subunits are joined to each other by interactions between the rRNAs in one subunit and proteins in the other subunit.
Ribosomes are located inside the cytosol found in the plant cell and animal cell.
The ribosome structure includes the following:
It is located in two areas of cytoplasm.
Scattered in the cytoplasm.
Prokaryotes have 70S ribosomes while eukaryotes have 80S ribosomes.
Around 62% of ribosomes are comprised of RNA, while the rest is proteins.
The structure of free and bound ribosomes is similar and is associated with protein synthesis.
Ribosomes Function
The important ribosome function includes:
It assembles amino acid to form proteins that are essential to carry out cellular functions.
The DNA produces mRNA by the process of DNA transcription.
The mRNA is synthesized in the nucleus and transported to the cytoplasm for the process of protein synthesis.
The ribosomal subunits in the cytoplasm are bound around mRNA polymers. The tRNA then synthesizes proteins.
The proteins synthesized in the cytoplasm are utilized in the cytoplasm itself, the proteins synthesized by bound ribosomes are transported outside the cell.
Frequently Asked Questions
What is the function of the ribosome?
Ribosomes are the organelles that help in protein synthesis. Protein is required for many cell activities such as damage repair and other chemical processes.
What is a ribosome composed of?
A ribosome is composed of two subunits:
the small ribosomal subunits- these read the mRNA
the large ribosomal subunits- they form polypeptide chains of amino acids.
How does the ribosome work?
The ribosomal subunits come together and combine with the mRNA during protein synthesis. They bind to the mRNA and start the synthesis of proteins.
What are the two different types of ribosomes?
The two different types of ribosomes include:
70 S-found in prokaryotic cells
80 S-found in eukaryotic cells
How are prokaryotic ribosomes different from eukaryotic ribosomes?
Prokaryotic ribosomes include three individual rRNA molecules and contain the large ribosomal subunit, the 80s.
Eukaryotic ribosomes include four individual rRNA molecules and contain the small ribosomal subunit, the 70s.
