Which group was not present in Linnaeus' system but is present in modern classification systems? A) Species B) Kingdom C) Domain D) Phylum HELP ME
Answer:
D) Phylum
Explanation:
The group that was not present in the Linnaeus' system but is present in modern classification systems is Domain. The correct option is C.
What is Linnaeus classification system?The Linnaean classification system is based on a hierarchy of groupings known as taxa. Taxa vary from kingdoms to species.
The kingdom is the most extensive and inclusive grouping. It is made up of organisms that have only a few basic resemblances.
The Linnaean system is significant because it paved the way for the use of binomial nomenclature to distinguish between species.
Scientists could communicate instead of using misleading common names once the system was implemented.
Domain is a group that was not present in Linnaeus' system but is present in modern classification systems.
Thus, the correct option is C.

In which biological event is chemical energy transformed into mechanical energy?
O muscular movement
O
photosynthesis
O bioluminescence
Muscular movement is the correct answer
The event in which the chemical energy transformed into mechanical energy is muscular movement. The correct option is A.
What is muscular movement?Muscles contract and then relax to move body parts. Muscles can pull bones, and yet they can't push them back into position.
As a result, they function in pairs of flexors and extensors. To flex a limb at a joint, the flexor contracts.
We discussed the skeletal system and the gestures that can take place at joints, such as flexion, extension, abduction, inversion, and so on.
These movements are produced by skeletal muscles pulling bones in different directions.
When ATP is hydrolyzed during cross-bridge cycling, chemical energy is converted to mechanical energy during muscle contraction.
As the muscle deforms or performs external work, this mechanical energy is distributed and stored in the tissue.
Thus, the correct option is A.

for an enzyme to be able to catalyze a reaction, the active site must —
Answer:
Active site of an enzyme must be attached to a substrate
Explanation:
Active site of an enzyme must be attached to a substrate
For an enzyme to be able to catalyse a reaction, the active site must bind with the specific substrate. This is referred as 'enzyme-substrate' complex.
Why do enzymes catalyse a reaction?Enzymes have the property of catalytic activity. All the enzymes are proteinaceous in nature. Enzymes specifically bind with the substrate and thus initiates a catalytic reaction. This is referred as enzyme-substrate specificity.
Enzymes associate with the substrate at a specific site by lowering the activation energy. This forms the active site where the reaction occurs. The substrate thus transforms into the product upon the action of enzyme.
Enzymes are unique as they speed up any chemical reaction. They help in achieving the equilibrium at a faster rate. Daily thousands of enzymatic reactions are carried out in the body.
Thus, enzymes are important in the biochemistry as they persuade chemical reactions.

Bob has brown hair and Sally has blonde hair. If brown hair is dominant and blonde hair is recessive, is it possible for Bob and Sally to have a blonde-haired child? Use the GENOTYPE of each parent to EXPLAIN your answer.
Answer:
Yes, it is possible.
Explanation:
Bob could either be h.o.m.ozygous (BB) for brown hair or h.e.terozygous (Bb) for brown hair. If Bob is h.e.t.erozygous for brown hair, this means he has a blonde hair allele. For a child to be blonde, the child needs one blonde allele from each parent and this is possible if Bob has a blonde hair allele. However, it is not possible if Bob is h.o.m.ozygous for brown hair.
In the image, there is a punnet square showing the possible genotypes of the children if Bob is h.e.t.erozygous for brown hair.

which level of an energy pyramid has the least amount of food energy?
Answer: Tertiary consumers receive 10% of the energy available at the secondary level (0.1% of the original energy). As a result, tertiary consumers have the least amount of energy and are therefore at the top of the pyramid (the smallest part).
All cells come from other cells. New cells are created by a process called cell division. To start cell division, a cell grows bigger and makes copies of the parts inside it. Then, the cell and its parts separate into two new cells. Each new cell contains the same types of cell parts as the original cell. Later, each of these cells may divide again to form more cells. When a multicellular organism's cells divide, the organism can grow. Each resulting cell is part of that organism. When a unicellular organism divides, each resulting cell is a separate unicellular organism. The micrographs below show cells from two different organisms: Giardia, a unicellular protist, and banana, a multicellular plant. Giardia cells in a banana Which of the following statements are true? Select all that apply.?
a. A rose bush cell can divide to form two rose bushes
b. If the bacterium divides, it will become a multicellular organism
c. When a rose bush cell divides, it copies its parts then divides into two cells
d. The bacterium was formed when another bacterium divided
Answer:
c. When a rose bush cell divides, it copies its parts then divides into two cells and
d. The bacterium was formed when another bacterium divided
Explanation:
C is correct because the cells inside are part of a larger being (the rose bush), when they divide they are simply creating more cells (hence making the rose bush grow).
D is correct because bacterium are unicellular organisms, meaning they are themselves single cells that are organisms, unlike the rose bush consisting of many cells.

been before and the only food available was rice? Which birds would be most successful? Which
birds would be least successful?
Answer:
the birds would either have two choices. they can eithe starve or they could adapt and eat the rice. they eventually would adapt if they wanted to stay alive and thrive or they would simply become extinct
Explanation:
If all of the bird types in this activity flew to an island where no birds had been before and the only food available was rice then they either starve or adapt and eat the rice.
What is adaptation?An adaptation can be defined as the heritable behavioral, morphological, or physiological trait which has evolved through the process of natural selection of a species, and maintains or increases the fitness of an organism of a species under a given set of environmental conditions and time.
In this activity, if all of the bird types flew to an island where no birds had been before and the only food available was rice then they either starve or they could adapt and eat the rice. However, they eventually would adapt if they wanted to stay alive on that island and thrive or they would simply become extinct.

How does your body respond to a decrease in blood glucose
Answer:
When blood sugar drops too low, the level of insulin declines and and other cells in the pancreas release glucagon, which causes the liver to turn stored glycogen back into glucose and release it into the blood. This brings blood sugar levels back up to normal
why is the concentration of oxygen in the body cells lower than the concentration of oxygen in the alveolus?
A. Alveolus can produce oxygen.
B. The exchange of gases occur in the alveolus.
C. Oxygen is used up for respiration I the body cells.
S. Oxygen diffuses out from the body cells.
Answer:
i think the answer should be b.
the alveolus is the site of exchange of gases (carbon dioxide and oxygen) between the body cells and the alveolar air. diffusion requires a concentration gradient, which basically means that there has to be a difference in concentration of the substance (in this case it's oxygen) between the 2 areas (in this case it's the body cells and the alveolar air) hence, there is more oxygen in the alveolar air than the body cells (this difference in concentration is what allows diffusion of oxygen from a region of HIGHER to LOWER concentration!) this allows oxygen to diffuse from alveolus to body cells, giving your body the oxygen it needs!
btw keep in mind that i am by no means an expert in biology (because im still a student), but b is the most logical answer to me. good luck!

Explanation:
Answer:
Ok, in the diagram it looks like there are arrows pointing to its mouth and its rear end right so my best guess would be that the rabbit eats the food, some of the mass is turned into energy and the rest of it goes out the rear end. I'm assuming they want you to explain how mass is turned into energy and travels throughout the body.

what is mauna loa volcano intensity?
Answer:
And over time, volcanoes made from low lava viscosity are wide and have a shallow slope; these are known as shield volcanoes. Classic examples of shield volcanoes are Mauna Kea and Mauna Loa in Hawaii, as well as Olympus Mons on Mars. When lava has a high viscosity, it's very thick and doesn't flow very well at all.
9,600 cubic miles
Mauna Loa is the largest volcano on Earth with an estimated volume of 9,600 cubic miles (40,000 cubic kilometers). It makes half of the area of the Island of Hawaii. Mauna Loa began to form nearly a million years ago. There is a caldera, Mokuaweoweo, at the summit and rift zones extend to the northeast and southwest.
