Answer:
The structure of ecosystems can be visualized with ecological pyramids, which were first described by the pioneering studies of Charles Elton in the 1920s. Ecological pyramids show the relative amounts of various parameters (such as number of organisms, energy, and biomass) across trophic level
Explanation: hope it helps
Answer:
Explanation:
A pyramid of numbers shows graphically the population, or abundance, in terms of the number of individual organisms involved at each level in a food chain. This shows the number of organisms in each trophic level without any consideration for their individual sizes or biomass. The pyramid is not necessarily upright
Ion pumps and phagocytosis are both examples of
________.
a. endocytosis
b. passive transport
c. active transport
d. facilitated diffusion
Answer:
A
Explanation:
EDGE2021
Ion pumps and phagocytosis are both examples of active transport. Therefore, the correct option is C.
The movement of molecules or ions across the cell membrane against a gradient of concentration, from an area of lower concentration to an area of higher concentration, is called active transport. In this whole process energy must be used in the form of ATP (adenosine triphosphate).
Ion pumps are membrane proteins that actively transport ions across the concentration gradient across the cell membrane. These ions include sodium, potassium, calcium or hydrogen ions. The ion concentration imbalance required for many cellular functions is maintained by these pumps.
On the other hand, phagocytosis is a type of endocytosis in which cells engulf large molecules or solid particles and internalize them. Energy is required for the formation of pseudopods and for the solubilization of substances in the phagosome inside the cell.
Therefore, the correct option is C.

Explanation:
What type of microbe is used in a vaccine .
Answer:
answer is below
Explanation:
Several of these structures have been used to generate bacterial vaccines. Toxoids are chemically inactivated toxins from bacteria like Clostridium tetani or Corynebacterium diphtheria. The infection with these bacteria itself does not cause the illness, but rather the exotoxins released from the bacteria.
Vaccines are made from microbes that are dead or inactive so that they are unable to cause disease. The antigen in the vaccine is the same as the antigen on the surface of the disease-causing microbe. The vaccine stimulates the body to produce antibodies against the antigen in the vaccine.

Imagine sperm and egg cells have 46 chromosomes like other cells in the body. That
is they have 46 chromosomes when a sperm cells fertilizes an egg cell. Would that
affect the total number of chromosomes in their offspring or children? Tell why or why
not.
Answer:
When an egg and sperm having 46 chromosomes similar to the body cells, their fertilization produces offsprings or children with 92 chromosomes which are double number of chromosomes as compared to parent cell. So they are not similar to parents. As we know that fertilization is the process of fusion of gametes and paring up of chromosomes. The offsprings are different from their parents in having more chromosome sets.

What is poisonous enough to kill 100,000 turkeys? That’s the question asked by scientists who studied a mass die-off of turkeys in Great Britain. It turned out that all the turkeys had eaten peanuts from Brazil. A fungus was growing on the peanuts. The fungus produced a dangerous poison called aflatoxin. Aflatoxins cause stomach pain, lung failure, cancer, and death in people and animals.
Farmers make a great effort to prevent fungi from growing on their stored crops. In a pile of grain or nuts, fungi have plenty of food and living space. The best way for farmers to prevent fungi from growing is to make sure there is not enough for fungi to survive and grow.

1. What percentage of puppies would have the same genotype as the
parents, Ww?
Answer:
50%
Explanation:
This question involves a single gene with two alleles W and w in puppies. According to the question, the genotype of the parent organisms are Ww. In a cross between the two parents i.e. Ww × Ww, the following gametes will be produced by each parent: W and w.
Using these gametes in a punnet square (see attached image), the following genotype of offsprings will be produced: WW, Ww, Ww, ww. Hence, based on this question, the percentage of puppies that would have the same genotype as the parents, Ww are 1/2 × 100% = 50%.

Invert syrup is a widely used sweetener, especially in candies and highly processed foods. Invert syrup can be made by treating sucrose with either an enzyme called sucrase or by heating sucrose with an acid. The end result is the same: each molecule of sucrose is hydrolyzed, resulting in _
Answer:
one glucose and one fructose molecule
Explanation:
Generally, inverted sugar is a mixture of two monosaccharides or simple/reducing sugars. More specifically, inverted sugar is a mixture of glucose and fructose.
Sucrose is a disaccharide containing one molecule of glucose and one molecule of fructose. Hence, when hydrolyzed, the glycosidic bond linking the glucose molecule with the fructose molecules becomes broken and the resulting product is a mixture of glucose and fructose molecules in equal proportions.

Why do mapping experiments become less accurate when the distances between genes become large? View Available Hint(s) Why do mapping experiments become less accurate when the distances between genes become large? Interference is greater when the distance between genes is large. Multiple crossovers are more common. Crossover gametes become less common. Recombination occurs less frequently in long chromosomes.
Answer:
Multiple crossovers are more common.
Explanation:
Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.
A mapping experiment refers to an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
In mapping experiments, if the genetic distance increases, there would be a consequential increase in multiple crossovers causing a recombinant with an odd number of crossovers and a parental combination with an even number of crossover events by switching it back.
Hence, mapping experiments become less accurate when the distances between genes become large because multiple crossovers are more common.

Which is a possible outcome for future generations of farmers if the same crop is planted on the same patch of land every year?
the soil could become infertile due to the lack of time for nutrients to be reinserted
the crops could become resistant to pests and insects through natural selection
the soil could become drought resistant due to the shallow root structure that would form
the crops could begin to change their genetic makeup due to mutations from the parent plants
Answer:
A
Explanation:
I hope this helps :)
The soil could become infertile due to the lack of time for nutrients to be reinserted. So, the correct option is (A).
What is Soil?Soil is also defined as earth or dirt which is a mixture of organic matter, minerals, gases, liquids and organisms which together support life. These are distinguished from silt by restricting the former term specifically to displaced soil.
It provides many important services for both people and the planet by putting food on our plates, purifying our water, protecting us from floods and combating drought. Soil is also important in combating climate change because it captures and stores large amounts of carbon. Without healthy soil there is no food security.
Whereas growing the same crop year after year reduces the availability of certain nutrients and depletes the soil. Monoculture leads to soil exhaustion when the soil becomes deficient in these nutrients.
Thus, the soil could become infertile due to the lack of time for nutrients to be reinserted. So, the correct option is (A).
