Which of the following statements about secondary consumers is false?
a. reproduce more slowly than primary consumers
b. are larger than primary consumers
c. are smaller than tertiary consumers
d. could be more regerred to as "carnivoires"
e. are more numerous than primary consumers
Answer:
e
Explanation:
The correct answer would be that they are more numerous than primary consumers.
Secondary consumers are never more numerous than primary consumers. This is primarily due to the fact that the higher we move up the food chain, the less efficient the amount of energy derived from food. Up to 90% of energy is sometimes lost at each trophic level as we up. Due to this inefficiency, the available food at top consumer levels can only support a few organisms. Hence, the higher we move up the food chain, the lesser the number of organisms the available food can support.
The correct option is e.

What are different types of biomolecules ?Biomolecules are the primary building block of the living cell such as Carbohydrates, Proteins, Fats, Nucleic Acids; Carbohydrates are polyhydroxy aldehydes or ketones collectively called as saccharides.
It can be monosaccharide made up of single sugar molecule like glucose, fructose or polysaccharide made up of many sugars like cellulose, starch.
Proteins are polymers of amino acids, structurally can be classified into primary, secondary, tertiary and quaternary protein.
Nucleic acids are up two types namely, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), DNA carry the genetic material which can be transferred to RNA by transcription and then to protein by the process of translation.
The basic components of nucleic acids are composed of a nitrogenous base, pentose sugar, and phosphate.
Lipids are organic and water insoluble substance, soluble only in non-polar solvent, they include sterols, fat-soluble vitamins, mono-, di- or triglycerides, phospholipids, etc.

Both plant and animal cells contain -
A. mitochondria, cell membrane, and chloroplasts.
B. a cell membrane, cytoplasm, and nucleus.
C a cell membrane, cell wall, and nucleus.
D. mitochondria, a cell wall, and chloroplasts.
Both plant and animal cells contain a cell membrane, cytoplasm and nucleus because animal cell does not contain cell wall and plant cell have cell wall but both of the cell contain cell membrane, cytoplam and nucleus.Thus option B is correct.
What is the difference between plant and animal cell?Plant cell consist cell wall but in animal cell, cell wall is absent. Nucleus is present in both of the cell. animal cell does not contain cell wall and plant cell have cell wall but both of the cell contain cell membrane, cytoplam and nucleus.
The main function of vacuoles present in plant cell as it help in storage of waste materials in a plant cell and maintain a proper pressure in a plant cell.

Which best describes biotechnology? the process of analyzing DNA samples to identify individuals involved in criminal activities DNA made by connecting fragments of DNA with desired traits from different DNA sources the field of biology that uses genetic engineering to produce crops, pharmaceuticals, and enzymes for use in industry and manufacturing the process of cutting DNA into fragments and inserting the fragments with a desired gene into another organism
Answer:
the exploitation of biological processes for industrial and other purposes, especially the genetic manipulation of microorganisms for the production of antibiotics, hormones, etc.
Answer: The correct answer is- a field of biology that makes the use of genetic engineering in order to produce crops, pharmaceuticals, and enzymes that are used in industry as well as manufacturing processes.
Biotechnology can be described as the manipulation of life forms or their components so as to produce useful commercial products such as crops that are resistant to pest, pharmaceuticals, useful enzymes. The manipulation is done using genetic engineering.
As a result of new products, advancement is made in the form of increased yield of crop, medicinal breakthrough or improvement in health.
1. Analyze Graphs What trend in the monarch population does the graph show?
Answer:
Let's analyze the graph.
we can see that in 1995, the total area occupied was around 8 he.
Then we have a steep increase, reaching a maximum in the year 1997, where the area occupied was 20 he.
After that the area decreases abruptly and remains (varying a little from year to year) around 5he
Now we can look at the year 2006, that year the area was around 5he, ut after that we can see an almost constant decrease in the area, where each year (except from 2010 to 2011) the area decreased.
Ending in 2014 near 1 or 2 hectares.
The conclusion that we can take from this graph is that, while some years ao the area fluctuated around some values, in recent years we can see a clear decrease in the area ocuppied by the Overwintering Monarchs.

If water was removed from reaction depicted above which of the following describes the most likely outcome of this removal
Answer:
The reaction will not occur.
Explanation:
If water was removed from reaction so the reaction will not occur or take place because water is a raw material in this reaction which will react with other atom or molecule forming new products. Example of such type of reaction are photosynthesis and formation of acid and base. In the process of photosynthesis, water is a raw material react with carbondioxide forming glucose and oxygen whereas water react with salt produces acid and base. Both of these reactions are impossible without water.

2.) From where do lion cubs get their chromosomes? How does this happen to produce the pattern that you see?
Answer:
This question is incomplete
Explanation:
This question is incomplete.
However, lions have 38 chromosomes (19 pairs) and there cubs get their chromosomes from there parents; with each parent donating 19 each. They also have a pair of chromosomes known as sex chromosomes (X and Y). The female always donates the X chromosome and the male donates either a X (which leads to a female cub) or a Y (which leads to a male cub), just like in many mammals.
NOTE: Chromosomes are threadlike structures in the nucleus of a cell that carry/stores genetic materials/genes.
Why must the cell move things in and out of it?
Answer:
Moving things in and out of the cell is an important role of the plasma membrane. It controls everything that enters and leaves the cell. There are two basic ways that substances can cross the plasma membrane: passive transport, which requires no energy; and active transport, which requires energy.

What is the expected result when the end product of a metabolic pathway binds to an enzyme in that pathway?
Answer:
Feedback inhibition.
Explanation:
It is feedback inhibition pathway because it is a cellular control process in metabolic part wat in which the output of a metabolic pathway binds to an enzyme at the regulatory sites which is distinct from the active sites of the substrates, causing a conformational changes on the enzyme which then makes it to slow down or inhibit it's production or synthesis.
This help to prevents excess of the high levels of the product from accumulating in the cell
The carbon cycle includes processes that release carbon into the atmosphere and places that act as carbon reservoirs. The diagram below shows both major processes that release carbon and major carbon reservoirs. Which of these disruptions would cause an excess output in the carbon cycle?
A. The destruction of terrestrial biota.
B. Increases in marine biota.
C. A reduction in the use of fossil fuels.
D. A thickening of ocean sediments.
Answer:
A
Explanation:
The destruction of terrestrial biota cause an excess output in the carbon cycle.
What are the features of carbon cycle?The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, geosphere, hydrosphere, and atmosphere of the Earth.
The carbon cycle is vital to life on Earth. Nature tends to keep carbon levels balanced, meaning that the amount of carbon naturally released from reservoirs is equal to the amount that is naturally absorbed by reservoirs.
Plants constantly exchange carbon with the atmosphere. Plants absorb carbon dioxide during photosynthesis and much of this carbon dioxide is then stored in roots, grasslands, and forests.
