Answer:
A scientist would ask a different question when he or she founds that the observed results are different from the expected results.
Explanation:
When one expects something and gets something else, then one is having a big enough cause to ask for new questions and initiate a new investigation. Scientific investigation is the process by which the researchers and scientists use a planned approach to answer questions regarding the world around us.You look at a cell using a microscope. You see ribosomes and a nucleoid that has one circular chromosome and no surrounding membrane. You do not see any endoplasmic reticulum, mitochondria, Golgi or chloroplasts. From these observations you would conclude you were looking at Group of answer choices

Which statement is FALSE?Question 39 options: Water can hold an unlimited amount of oxygen. Water can hold less oxygen than air can. Underwater organisms need oxygen. A small decrease in dissolved oxygen can have an effect on aquatic life. Underwater organisms use oxygen in cellular respiration.
Answer: Water can hold an unlimited amount of oxygen.
Explanation:
Water cannot hold an unlimited amount of oxygen because it would get to a point where it is saturated as it needs to hold Hydrogen as well. Air on the other hand, has significantly more space for oxygen as it contains only 21% and can keep taking more.
Underwater organisms need oxygen for respiration and a small decrease in the oxygen available in water affects aquatic life because they rely on it to survive.
•Differentiate between virus and viroids.
Viruses (Virus particles or virions) are usually units consisting of nucleic acids and coat proteins called capsids.
Viroids consist only of RNA, i.e. they contain no protein at all. Except for a few cases, viruses are not surrounded by a membrane.

Why is avian influenza (H5 N1) rarely transmitted from poultry to humans? Why is it is often lethal
in humans? Why is it rarely spread from person to person?
Answer:
Lacks the right key to unlock many cells.
Explanation:
Avian influenza (H5 N1) rarely transmitted from poultry to humans because it lacks the right key to unlock many cells in the upper respiratory tract so due to this action the virus is rarely transmitted to humans. Sometimes it is lethal to humans due to absence of antibodies for this type of virus. It is rarely spread from person to person due to inability to enters the other human body.

Explanation:
Elements in the same group have same properties, because they have the same number of valence electrons.
In the Avery, MacLeod, and McCarty experiment, the transforming extract from virulent bacteria was treated with DNase, RNase, or protease before being mixed with nonvirulent bacteria. The appropriate control for this experiment is to treat the transforming extract from heat-killed virulent bacteria with:
Answer:
Nothing
Explanation:
A. Control variables generally entail little or no system change. To see if the method worked, the researchers required a positive control in which the heat-killed virulent bacteria invariably transformed the non-virulent microorganisms. This positive control involves adding "nothing" to both the heat-killed virulent bacteria before mixing them with the non-virulent bacteria.

Sustainable practices refer to the practices, services, and guidelines we develop to protect ourselves within our environment.
True
False
Answer: True
Explanation:
Sustainable practices refer to the practices, services, and guidelines that are developed in order to protect ourselves within our environment.
Sustainable practices support human, ecological, economic and human health. With sustainability, it's agreed that there are finite resources and they should be used conservatively and maintained for future generations.
The statement is true.
Answer:
False; I did the quiz and I answered "True" and got it incorrect
You are studying nuclear lamins and use recombinant DNA technology to alter the coding sequence of a nuclear lamin gene. The alteration you make creates a situation such that the gene now codes for a nuclear lamin protein that can no longer be phosphorylated when the nuclear envelope is broken down during mitosis. What do you predict would happen if the cell only had the altered nuclear lamin gene (and not the unaltered version)
Answer:
Nuclear lamins will no longer disassemble during mitosis
Explanation:
The nuclear lamina is a fibrillar network inside the nucleus of eukaryotic cells, between the inner nuclear membrane and the peripheral chromatin. Nuclear lamins (also called simply lamin proteins) are intermediate filament-type proteins and represent the major building blocks of the nuclear lamina. During mitosis, the nuclear lamina is disassembled by hyperphosphorylation of nuclear lamins and lamina-associated proteins. The protein responsible for phosphorylating nuclear lamins is p34cdc2, a protein kinase that has a key role in controlling cell cycle progression. In consequence, a mutant form of the nuclear lamin proteins that cannot be phosphorylated will no longer be able to disassemble during mitosis.

Answer:
Life is a characteristic that distinguishes physical entries that have biological processes,such as signaling and self-sustining processes from those that do not, either because such functions have ceased,or because they never had such functions are classified as in animate.

Why are
there no gram-positive archaea species, but there are gram-positive
bacteria species?
Answer:
There are no gram positive archaea because archaea lack peptidoglycan in their cell walls, meaning that the archaeic cell walls are more similar to gram negative bacterial walls, although they do show a greater variety of cell wall types.
EXPLANATION
Bacteria can be divided into gram-positive bacteria and gram-negative bacteria because of their cell wall composition. The cell wall of gram-positive bacteria is made up of peptidoglycan which retains crystal violet stain and appears purple in color under microscope. The cell wall of gram-negative bacteria has an outer layer of lipopolysaccharide which do not retain crystal violet color and appear pink. The cell wall of archaea is not made up of peptidoglycan but is made up of pseudo-peptidoglycan, therefore, no gram-positive archaea species is present on the earth.
On your first research mission you make an amazing discovery by finding a new species living in the hostile environment of the Sahara desert. After observing it carefully you determine that it is not an autotroph, it is multicellular, and it does not contain any chitin. What is the best classification for it
Answer:
Animalia
Explanation:
A multicellular organism is an organism composed of two or more cells. Multicellular organisms include animals (i.e., organisms from kingdom Animalia), plants, and most fungi. Moreover, an autotroph is a living organism that can produce its own food by using materials from inorganic sources (e.g., water, carbon dioxide, etc); whereas a heterotroph is an organism that cannot produce its own food and thereby needs to eat other organisms, like plants or animals, to survive. Multicellular autotrophs are typically plants; whereas multicellular heterotrophs include all animals, fungi and some parasitic plants. Finally, chitin is a polysaccharide (polymer) of N-acetylglucosamine, which is found in the cell wall of fungi, as well as in the exoskeleton of some animal groups such as, for example, insects, crustaceans, etc.
WHY ARE THE TROPHIC LEVELS AND ENERGY REPRESENTED IN THE FORM OF PYRAMIDS?
Answer:
An energy pyramid shows the distribution of energy among trophic levels. Producers use energy from sunlight to make food. Herbivores eat plants—the producers—to get energy. ... Each level above gets smaller, because as energy is lost as heat, there is less energy avail- able as food for organisms.
