In which group will you place an organism that does not have definite nucleus
Answer:
Prokaryotic
Explanation:
HELP!! Orchids are flowering plants that depend on bees for pollination. A population of orchids in a rainforest has reached its carrying capacity. The size of the rainforest's bee population is a limiting factor of the orchid population. What will happen to the orchids' carrying capacity if the rainforest's bee population decreases?
Answer:
The carrying capacity will decrease because the level of the limiting factor decreases.
Explanation:
Decrease in available resources lead to decrease in carrying capacity of an environment for a population. The rainforest's bee population is a limiting factor for orchid population, decrease in bee population will lead to decrease in orchid population.
Hence, the carrying capacity will decrease due to decrease in limiting factor as the number of orchids that can be sustained by the environment would decreases.

Which correctly lists three different geologic features that help scientists determine the relative ages of rocks by their positions? 1.magma, erosion, and intrusions 2.erosion, magma, and cross-cutting relationships 3.intrusions, index fossils, and magma 4.index fossils, intrusions, and cross-cutting relationships
Answer:
4.index fossils, intrusions, and cross-cutting relationships
Explanation:
There are various geologic features or phenomenon that determines the relative ages of rocks . This geologic features or events includes index fossils , intrusions, cross cutting relationship etc. Note relative ages of rock does not give the actual ages oft the rocks but instead compares the ages of these rocks. Knowing the relative ages of rocks, one can decipher which rock is older or which one is younger. The geologic features give details on the sequence of event that happens through the formation.
Like the principle of cross cutting relationship states that the geologic feature which cut across or intrudes another geologic feature is younger than it surrounding rock.
Index fossils are remains of organisms that are widely spread. The deposition of this remains can give the sequence for deposition of the surrounding rocks which these fossils are found.
Intrusions occurs when geologic features like plutons invades another rock body. Geologically, the plutons will be younger than the surrounding or host rock.
The correct list of three different geologic features that help scientists determine the relative ages of rocks by their position is option 4, "index fossils, intrusions, and cross-cutting relationships".
Index fossils are used by geologists as clues to determine the age of rocks. These fossils are useful because they contain the remains of certain organisms, which scientists can relate to a specific period in time, thus offering clues as to the age of the rocks that surround them.
Intrusions are when magma dries and forms its own layer above other rocks. Scientists use these as clues as to the age of the other rocks because whenever this happens, we can know that the dried magma is younger than the surrounding rocks.
Finally, cross-cutting relationships are when one form of rock cuts through the layers of other rocks, this follows a geological rule which states that the cross-cutting rock will be younger than the others, offering yet another clue to the age of the rocks.
For these reasons, the correct list of geologic features that help scientists determine the relative ages of rocks by their position is option 4, "index fossils, intrusions, and cross-cutting relationships".

Answer:
Organisms better adapted to the environment
Explanation:
According to the evolutionary theory proposed by Charles Darwin in "The Origin of Species" (1859), the fittest organisms are those that are better suited to the environment (i.e., have a higher fitness). These organisms have more chances to survive and reproduce, and thereby they have also more chances to leave their genes in the next generation. This process is the central concept of evolution, and it is called natural selection. In consequence, evolution produces phenotypic changes or 'adaptations' that are inherited by organisms over generations, and certain traits are lost during this process.

2. How might a mutation that causes a single letter change in the DNA sequence affect
your protein structure and function?
Answer:
A mutation that causes a single letter change in the DNA sequence can affect your protein structure and function because the sequence of letters in a gene determines the sequence of amino acids in the protein that it encodes. A single letter change in the DNA alters the mRNA which alters the amino acid sequence of the resulting protein and sometimes that can cause serious results if it changes the way a protein works.

Answer:
DNA is consist of two strands that are coiled together to form a double helix structure in which both the strands are anti-parallel. The direction of one strand is from 5' to 3' and the other has 3' to 5'.
DNA is made up of nucleotide, phosphate group and deoxyribose sugar. The two anti-parallel strands on DNA are composed of nucleotide and bonded with hydrogen bond. There are four nitrogenous bases present in each nucleotide e adenine (A), guanine (G), Thymine (T) and cytosine (C). Where A and T are bonded with double hydrogen bond and G and C are bonded with triple hydrogen bond present complementary to each other in both the strands.

When people have their gallbladders removed, their bodies no longer have a place to store bile, and the bile flows from the liver continuously. What effect might this have on their ability to digest fats?
A. There will be very little change since bile will still be present to emulsify fats.
B. Fats will be emulsified more efficiently with the constant flow of digestive enzymes.
C. It will be unlikely that they will be able to emulsify and digest fats.
D. Only small amounts of fats will get digested since high concentrations of bile enzymes are needed for efficient digestion.
Answer:
A. There will be very little change since bile will still be present to emulsify fats.
Explanation:
The gallbladder is a pear-shaped storage sac present in the alimentary canal of humans and functions to store excess bile in between meals. The bile is a greenish-yellow substance composed of different substances like salts, bile pigments, cholesterol etc. The bile is produced in the liver and aids in the digestion of fats.
The gallbladder serves as an intermediary between the organ of bile production (liver) and its destination (intestine). According to the question, once the gallbladder is removed, there is no longer a place to store bile. However, bile will still be produced by the liver and released directly into the intestine instead.
Hence, the bile will still be present to perform its function of emulsifying fats with little changes in the way it is released into the intestine. Note that, the gallbladder only regulates the speed at which the bile is released into the intestine.
Which of the following choices is not a function of the Golgi apparatus?
A. producing proteins

C. storing proteins
D. sorting proteins
Answer:
A. producing proteins
Explanation:
Protein synthesis takes place in ribosomes bounded to the rough endoplasmic reticulum. The Golgi apparatus performs all the other functions.
Hope this helps.
Producing proteins is not a function of the Golgi apparatus. So the correct option is A.
What is the Golgi apparatus?
A Golgi apparatus, also known as a Golgi body is an organelle in a cell. It helps in the processing and packaging of proteins and lipid molecules. It specially processes the proteins that are destined for export from the cell. It is named after Camillo Golgi, the scientist who discovered it. Its appearance resembles a series of stacked membranes.
The Golgi body is a cell organelle made up of membranes. These membranes are of different types. Some are tubules, and some are vesicles. This organelle is located near the nucleus. That is why it's called a perinuclear body. It lies right after the endoplasmic reticulum as well.
When the synthesized proteins are released from the endoplasmic reticulum, they enter the Golgi body for further processing. Processing may include the addition of carbohydrates and the formation of glycoproteins. These glycoproteins are released from the Golgi body to the rest of the cell.
These processed proteins are released and packed in vesicles. The vesicles are made out of the membranes in the Golgi network. These vesicles are filled with the products of the Golgi body and they move to the rest of the cell. This is usually through the cell to the plasma membrane, which is the destination.
Therefore, the correct option is A.

O A. Fructose molecules will diffuse into the cell.
B. Fructose molecules will disappear by diffusion.
C. Fructose molecules will stay where they are.
O D. Fructose molecules will diffuse out of the cell.
If the amount of fructose is more outside the cell than inside the cell, then fructose molecules will move into the cell through diffusion. The correct option is A.
What is osmosis?Diffusion is the movement of substances from a region of higher concentration to a lower concentration region. A gradient in Gibbs free energy or chemical potential aids in diffusion.
In the given scenario, as fructose molecule is in excess outside the cell and is less inside, then the fructose molecule will cross the membrane from outside the cell to inside due to this concentration gradient.
Thus, the correct option is A.

What kind of joint allows the arm to bend?
Cartilaginous
Suture
Fibrous
Synovial
Answer:
Hey there!
The correct answer would be Synovial. A synovial joint allows the arm to bend.
The synovial (or joint) cavity is this area, and synovial fluid is what fills it. By lubricating the joint and minimizing friction between the bones, synovial fluid enables better joint movement. Thus option D is correct.
What main role of Synovial joint in bend?Keeping the articulating bones of the joint cavity from rubbing against one another is the synovial joint's main function. All synovial joints are diarthroses, but the range of motion differs between different subtypes and is frequently constrained by the ligaments that hold the bones together.
Bones may move freely thanks to movable joints. Synovial joints are all joints that may move. They also encompass the elbow, hip, and shoulder in addition to the knee. The most prevalent type of joints in the body are those that can move.
Therefore, Synovial kind of joint allows the arm to bend.

If the snake trophic level is removed, the following things will happen
=> The mouse population will increase because they would no more be a prey
=> The bird of prey population will decrease because their predator is no more present
=> The sun would stay the same
=> The grass population would decrease as their predator population has increased.
The mouse population decreasing won't happen when the snake trophic
level is removed.
In the trophic level below, the snake feeds on the mouse, the bird of prey
then feeds on the snakes.
Sun→grass→mouse→snake→bird of prey
