The amount of available ______ limits the number of trophic levels in a community. please help!!!

Answers

Trophic levels
Explanation:
Decrease in energy at higher trophic levels limits the number of trophic levels in a food chain. When the number of links keep increasing, the amount of energy available decreases, as only 10% of energy gets transferred from one trophic level to the next.
The different feeding positions in a food chain or web are called trophic levels. Generally, there are no more than four trophic levels because energy and biomass decrease from lower to higher levels.

The properties of water are the result of multiple factors including; polarity and hydrogen bonding. Which property of water is not a result of polarity?

A.Water dissolves salts and sugars.
B.Water will become less dense when frozen.
C.Water is transparent and lets sunlight pass through.

D.Water will from a spherical bead due to surface tension

Answers

I honestly don’t know ok leave me alone

Water is transparent and lets sunlight pass through. Therefore, the correct option is C.

Water's transparency and ability to pass through sunlight is not just a product of its polarity. This is mainly because water absorbs only specific wavelengths of light, particularly those in the visible spectrum, while allowing other wavelengths to pass through. Rather than being a direct result of polarity, this property is related to the electrical structure of water molecules and their interactions with light. On the other hand, the interplay of water polarity and hydrogen bonding is the reason for the A, B and D properties, respectively.

Therefore, the correct option is C.

Fossil evidence indicates that the first organisms on Earth were single-called prokaryotes. The first eukaryotes are believed to have formed from these prokaryotes. How does the endosymbiotic theory explain the development of the first eukaryotic organisms?.

Answers

The study of fossils shows that the eukaryotic cells have been evolved from the prokaryotic cells. The endosymbiotic theory has been used to study the evolution of eukaryotic cells.

The endosymbiotic theory states that:

Endosymbiotic theory is also referred to as the theory of symbiogenesis. The theory explains the evolution of eukaryotic cells from prokaryotic cells.

The theory explains the presence of chloroplasts and mitochondria, and how these organelles form the eukaryotic cells. The theory explains the origin of mitochondria in animal cells and chloroplasts in plant cells.

Thus, the endosymbiotic theory defines the development of eukaryotic cells from the prokaryotic cells.

Which part of a cell is used by a virus to produce its protective protein coat?

Answers

A ribosome is the part of a cell is used by a virus to produce its protective

protein coat.

Virus produces a protective protein coat known as capsids  which serves as

a means of protection for the organism. The capsids are produced through

the organelle known as ribosome.,

The ribosome acts as a site for protein synthesis in organisms and the

capsids being made up of protein means the ribosome was used to

Mitosis maintains chromosomes in each {blank} while meiosis maintains chromosome number in the {blank}.

Answers

Answer:

Mitosis maintains chromosomes in each cell division constant, while meiosis maintains chromosome number in half

Explanation:

Mitosis maintains chromosomes in each daughter cell while meiosis maintains chromosome number in the gametes.

What is mitosis and meiosis?

Mitosis is the process by which a cell divides into two identical daughter cells, each with the same number and type of chromosomes as the parent cell. During mitosis, the cell's DNA is replicated, and the replicated chromosomes are evenly distributed into the two daughter cells. This ensures that each daughter cell receives a complete set of chromosomes, maintaining chromosome number in the daughter cells.

Meiosis, on the other hand, is the process by which a cell divides into four non-identical daughter cells, known as gametes. During meiosis, the cell's DNA is replicated, and the replicated chromosomes are shuffled through a process called crossing over. This shuffling results in gametes with unique combinations of chromosomes, which helps to maintain chromosome number in the gametes. Gametes, also known as sex cells, are the cells involved in sexual reproduction, and they are important for maintaining chromosome number in offspring.

what conditions prompt hemoglobin to release oxygen? select the three answers that are correct.

Answers

When blood is in the lungs,
where oxygen is plentiful, oxygen easily binds to the first subunit and then quickly fills up the remaining ones. Then, as blood circulates through the body, the oxygen level drops while that of carbon dioxide increases. In this environment, hemoglobin releases its bound oxygen.

The conditions that prompt hemoglobin to release oxygen are:

Decrease in pH (high acidity)

Exercise

Unloading of oxygen from haemoglobin

Haemoglobin is the blood protein that is used to carry oxygen in our body and gives blood its red colour. The ability of this protein to carry oxygen depends on some factor. These factors include:

Decreased pH: Upon the production of carbondioxide in the tissue cells, carbonic acid is produced which leads to decrease in pH of the blood.

Exercise: During exercise, the temperature of muscle increases secondary to its utilisation. This will cause the release of unloading of oxygen from haemoglobin.

Therefore, conditions that prompt hemoglobin to release oxygen are decrease in pH (high acidity) and exercise.

A elephant cell has 20 chromosomes. how many chromosomes will the cell have just before mitosis begins in the elephant cell?

Answers

The elephant cell will have 20 chromosomes.

Cells undergo interphase before getting to the mitotic phase. At the S phase of the interphase, the amount of DNA in the cell is double by replication. However, the number of chromosomes remains intact.

Thus, the cell gets to the mitotic phase with the same number of chromosomes that is usually present in normal vegetative cells of the animal.
