If the man did not eat during the bike ride, why do you think that his blood glucose
level never went below 4.5 mml/L
Answer:
Due to less conversion of glucose into energy.
Explanation:
If the man did not eat during the bike ride, his blood glucose level never went below because there is very little amount energy is used. If a person perform activities such as running and exercise etc, it requires more energy and for that more glucose is converted into energy and glucose level went down while on the bike ride very little amount of energy is needed and for that very little amount of glucose is converted into energy and the glucose level did not went below 4.5 mml/L.

chlorine gas (CI) is toxic and sodium (Na) is explosive? yet, together they make common table salt. why do they form a chemical bond?
A)together these two elements form a more stable molecule
B)sodium is a non metal and chlorine is a metal -nonmetals and metals always form a bond
C)chlorine is on the left side of the periodic table in group 1 and these elements always form bonds
D)chlorine has two protons and they transferred to sodium to form the salt molecule
Both ions have complete valence shells and are energetically more stable. I’d assume D because the protons need to transfer.

Answer: Not enough information
Explanation:
Write in the Functions of Each Organelle Describe the function of each organelle. Nucleus carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus. Ribosome Endoplasmic reticulum Golgi apparatus
Answer:
Explanation:
Ribosome works with ribonucleic acid to produce a functional protein. Translation takes place at the ribosome.
The endoplasmic reticulum helps in transport of proteins that are made by the ribosomes and folds them into sacs that are called cisternae from where it is moved to the Golgi apparatus.
Golgi apparatus served as store house for molecules that moved from endoplasmic reticulum. They are then released from the Golgi apparatus in what are called secretory vesicles into the cytoplasm.
Answer:
See the answer below
Explanation:
The nucleus is a double membrane organelle that is responsible for controlling the activities of the cell. It contains the DNA which carries the gene and the hereditary information of the cell.
The nucleoli are small spherical structures that are located within the nucleus which function in the formation of the ribosome and hence, important for protein synthesis in the eukaryotic organisms.
The ribosomes are structures within the cell which represent the site of protein synthesis. During protein synthesis, the mRNA and the tRNA attach themselves to the ribosome to form the translation complex for the initiation of protein synthesis.
The Golgi apparatus is a system of membrane responsible for the packaging and secretion of proteins and lipids within the cell.
Animal cells and plant cells both contain cell membranes that surround the outside of the cell. Plant cells have an additional outside layer, the cell wall.Select the statement(s) below that explain(s) why plants have the additional outer layer protection.Select ALL that apply.
A. The cell wall solely controls what enters and leaves the cell.
B. The cell wall provides structure for the plant, which allows it to grow up and out to absorb sunlight.
C. The cell wall is flexible and controls what enters and leaves the cell.
D. The cell wall is rigid and firm, limiting the cell shape.
Answer:
B
Explanation:
The cell wall provides structure for the plant, which allows it to grow up and out to absorb sunlight.
How can an abiotic factor like temperature impact the population size of an ecosystem
Answer/Explanation:
Abiotic factors are non-living factors such as temperature, light, water, humidity, acidity, etc.
They strongly impact the ability of organisms to grow and successfully reproduce, and therefore affect the diversity of organisms in any given area.
If the temperature, light, and water availability (for example) are optimal, then species of plants will be able to grow successfully. This increases their populatuion size. Not only that, but it also provides a greater food supply for the animals that eat the plants, so their population will also grow.

Diatoms are one of the most common types of phytoplankton in marine habitats. Like plants, diatoms contain chlorophyll and produce glucose from which of the following?
CO2 and O2
CO2 and H2O
O2 and ATP
ATP and H2O
Answer:CO2 and H2O
Explanation:
Diatoms produce glucose from CO2 and H2O.
The sun is the only source of energy in the ecosystem. Plants can trap this energy from the sun through the process of photosynthesis. Photosynthesis is the process by which green plants use energy from the sun to combine carbon dioxide and water to form glucose.
Hence, like plants, diatoms contain chlorophyll and produce glucose from from CO2 and H2O.

draw a well labelled diagram of a leaf structure and explain how the stomata ,the cuticle and the vascular bundle works
Answer:
A well labelled diagram of a leaf structure
Explanation:
Answer:
Vascular bundles are a collection of tube-like tissues that flow through plants, transporting critical substances to various parts of the plant.The cuticle reduces the rate of water loss from the leaf surface.Stomata are tiny holes found in the underside of leaves. They control water loss and gas exchange by opening and closing. They allow water vapour and oxygen out of the leaf and carbon dioxide into the leaf.Which statement correctly describes the relationship between genes, proteins, and traits?
Where is the main store of phosphorus ?
Answer:
Phosphorus is most commonly found in rock formations and ocean sediments as phosphate salts.
Answer:
The largest reservoir of phosphorus is in sedimentary rock. It is in these rocks where the phosphorus cycle begins. When it rains, phosphates are removed from the rocks (via weathering) and are distributed throughout both soils and water. Plants take up the phosphate ions from the soil.
Crossing over occurs when (4 points)
Answer:
Crossing over is the exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis, which results in new allelic combinations in the daughter cells.
When chromosomal homologs communicate with one another during Meiosis I's metaphase, crossing over takes place.
What is Crossing over?When chromosomes of the same type are paired together during meiosis, a biological event called crossing over takes place.
Parts of the chromosome can be exchanged when two chromosomes, one from the mother and one from the father, line up. The same genes may be present on the two chromosomes in different versions.
The exchange of genetic material between non-sister chromatids of homologous chromosomes occurs during crossing over, an enzyme-mediated process. It happens during meiotic prophase I's pachytene stage.
Crossing over occurs during Meiosis I's metaphase when chromosomal homologs interact with one another.
Thus, this way, crossing over takes place during meiosis.

Which of the following best defines the process of the cells, tissues, organs, and organ systems all working together to maintain a stable internal environment?
Group of answer choices
A. digestion
B.homeostasis
C. excretion
D. disequilibrium
Answer:
Process of the cells, tissues, organs, and organ systems all working together to maintain a stable internal environment are best defined by the term homeostasis (option B).
Explanation:
All living organisms perform their functions properly by maintaining some conditions of the internal environment constant, such as temperature, pH and amount of water or electrolytes. This also guarantees a healthy state and a longer life.
The maintenance of the organic balance is done by an internal regulation system, called homeostasis. Homeostasis means all the processes aimed at preserving the balance and fulfilling the organic functions properly.
The other options are not correct because:
A. Digestion is the process by which nutrients are converted into small molecules that are easily absorbed by the body.
C. Excretion is the process of eliminating waste from metabolic and organic processes.
D. Disequilibrium is the term applied to the failure or loss of ideal conditions or balance.

Two photographers take time-lapse photos of the night sky. One of them is at the equator. The other is at the south pole. Which photo will show stars that never rise or set? Explain
Answer: South pole.
Explanation:
The equator is filled with non-circumpolar stars which means the stars sets in the sky. The north and south pole is full of circumpolar stars which means they never set.
If two photographers take time-lapse photos of the night sky with one being at the equator and the other at the south pole, the photo by the photographer at the south pole will show stars that never rise or set.
The stars that never rise or set is known as the circumpolar stars and are usually found close to either of the earth's poles - north or south pole.
This means that the photographer at the equator which is an equidistance from the two poles will not be able to capture the circumpolar stars.

Describe two pathways the student can use to show how a metamorphic rock
could become another type of rock and then become metamorphic once again
Answer:
In order for a metamorphic rock to become a sedimentary rock, the rock must undergo erosion. Once the rock has eroded, it will produce rock fragments or sediments which accumulate to form a sedimentary rock. ... In turn, when igneous and sedimentary rocks are exposed to heat and pressure, the rocks become metamorphic.
Explanation:
hope this helps
Answer:
One pathway is that an igneous rock can apply heat and pressure to the rock which will become metamorphic. Another pathway is that a metamorphic rock can be changed by heat and pressure to form into a different metamorphic rock.
