Which of the following factors affecting population growth is density
independent?
A. Competition
B. Disease
C. Natural disaster
D. Predation
C. Natural disaster is a density-independent factor affecting population growth. Density-independent factors are those that affect the population irrespective of the population size or density.
How Natural disasters reduce population sizes?Natural disasters such as floods, hurricanes, earthquakes, and wildfires can reduce population sizes regardless of how many individuals were present in the population before the disaster occurred. The other factors listed - competition, disease, and predation - are all density-dependent factors, which means that they become more significant as the population size or density increases.
Competition is an example of a density-dependent factor, as it increases as the population size increases. As more individuals compete for limited resources such as food, water, and shelter, the rate of population growth slows down.
Disease is another density-dependent factor, as it spreads more easily in crowded populations where individuals are in close contact with one another.
On the other hand, natural disasters such as floods, hurricanes, and wildfires are examples of density-independent factors. These events can affect a population regardless of its size, and they can cause significant decreases in population size.
Predation can be both a density-dependent and density-independent factor. In some cases, predation can increase as the population size increases, making it a density-dependent factor. However, predators can also reduce the population size through random hunting or selective hunting of weaker individuals, making it a density-independent factor.
Understanding the factors that affect population growth is important for predicting and managing population sizes in both natural and human-made ecosystems.

10 differences between animal cells and plant cells
Answer:
Following are the difference to the given question:
Explanation:
Plant cells have a wall of a cell, while cells of animals wouldn't. Cell membranes offer plants support and shape.Chloroplasts in plant cells do not occur, however, in animal cells. Chloroplasts allow plants can grow things via photosynthesizing.Plant cells typically get a vacuole(s) that is one or even more big, whereas animal cells are vacuous, whether any.Large vesicles assist shape the plant and enable food and water to be store for future use.In animal cells, the storing function takes a smaller part and the vacuoles, therefore, are smaller.A plant cell is square in its structural way and an animal cell is often spherical and irregular.The cell of a plant has a vesicle in its big form which is significantly smaller than the plant cell, as well as the animal cell was the or more vacuoles. In general, a vacuole is a storage area for the cells to store water.There is no chloroplast inside the animal cell. Chloroplast is a plant cell that produces photosynthesis from its food. The plants have a green color.The nucleus is located throughout the cell of the plant on the other edge of the peripheral cytoplasm, while the nucleus is in the animal's core.Plant cells store food of starch while animal cells store food of glucose.The mitochondria in the plant are fewer and also have tube cristae, whereas the animal cells have grown in various.Describe your environment

What movement of the thumb would be most affected by lesion of the median nerve in the cubital fossa
Answer:
flexion
Explanation:
The flexion is a movement of the body part that is described the bending of an elbow, or the clenching a hand into a fist, etc. where the angle between any segment of the body and its proximal segment decreases.
In simple words, the flexion is a movement which decreases the angle between two body parts when they are moved.
The flexion occurs in the sagittal plane.
Thus, the movement of a thumb that would be mostly affected by the lesion of median nerve in cubital fossa is the flexion movement.

Transfer RNA has __________ bases attached to one end of the molecule and an amino acid to the other.
Answer:
Nitrogenous
Explanation:
Transfer RNA, also known as tRNA, is one of the three types of RNA. It is involved in the translation process. The shape of the tRNA allows it to be a very important component of the translation process.
The morphological structure of the tRNA is in such a way that a sequence of nitrogenous bases called ANTICODON attach to one of its ends while an amino acid is attached to the other end. This way the tRNA molecule is able to read the mRNA codon using its anticodons and carry the corresponding amino acids.
N.B; the anticodons are composed of three nitrogenous bases just like codons. Codons are complementary to anticodons.
When Adenosine Triphosphate is used, it breaks down into:
A. Glucose
B. It doesn't break down
C. Thymine Triphosphate
D. Adenosine Diphosphate
Answer:
D. Adenosine DIPHOSPHATE
Explanation:
ATP is hydrolysed to ADP in the reaction ATP+H20->ADP +Pi + energy
When Adenosine Triphosphate is used, it breaks down into Adenosine Diphosphate.
Adenosine diphosphate (ADP)
Adenosine diphosphate (ADP), also known as adenosine pyrophosphate (APP), is an important organic compound in metabolism and is essential to the flow of energy in living cells. ADP consists of three important structural components: a sugar backbone attached to adenine and two phosphate groups bonded to the 5 carbon atoms of ribose. The diphosphate group of ADP is attached to the 5’ carbon of the sugar backbone, while the adenine attaches to the 1’ carbon.
ADP can be interconverted to adenosine triphosphate (ATP) and adenosine monophosphate (AMP). ATP contains one more phosphate group than does ADP. AMP contains one fewer phosphate group. Energy transfer used by all living things is a result of the dephosphorylation of ATP by enzymes known as ATPases. The cleavage of a phosphate group from ATP results in the coupling of energy to metabolic reactions and is a by-product of ADP.ATP is continually reformed from lower-energy species ADP and AMP. The biosynthesis of ATP is achieved throughout processes such as substrate-level phosphorylation, oxidative phosphorylation, and photophosphorylation, all of which facilitate the addition of a phosphate group to ADP.

Forms of inheritance that do not follow typical Mendelian patterns and that appear to be more influenced by the parent contributing the most cytoplasm to the embryo are grouped under the general heading of ________.
Answer:
Extrachromosomal or cytoplasmic inheritance
Explanation:
Extrachromosomal or cytoplasmic inheritance refers to hereditability transmission controlled by cytoplasmic genes.
This form of inheritance lays in genes that are out of the nucleus. Information for some characters is placed in organelles in the cytoplasm, such as mitochondria and chloroplasts. These organelles have a well-defined portion of the total cellular genome.
Although mitochondrial inheritance is mostly maternal, recent studies have demonstrated that it might also be paternal.
Sperm cells hardly carry mitochondria, so mitochondrial DNI is mostly inherited from the maternal side. If there exists any mutation in this DNI, the whole progeny of the mutated woman will be affected, as they will get the mother´s mitochondria carrying the mutation. On the contrary, if there is a man affected by a disease caused by a mutation in mitochondrial DNI, non of their descendants will get the disease.

The Types 1-3 of survival growth are related to age, while exponential growth does not have any limits related to environmental capacity.
The correct answer is - logistic growth.
Why dont plant cells have microvilli?
Answer: They don’t have microvili because they don’t need it.
Explanation:
Animal cells have this because it increase surface area and helps absorb food and water molecules.
Plant cells do not have microvilli because they do not require the same type of surface area enlargement as animal cells.
Microvilli are small, finger-like projections that extend from the surface of animal cells. They help to increase the surface area of the cell, which is important for functions such as absorption and secretion.
Whereas plant cells have a rigid cell wall that provides structural support and protection. They have evolved unique structures to meet their specific needs, such as chloroplasts for photosynthesis and a cell wall for support and protection.
So, the absence of microvilli in plant cells is not a disadvantage since they do not require the same surface area enlargement as animal cells.
Therefore, the absence of microvilli in plant cells is due to their unique structural and functional needs.

The first column labeled properties of mixtures has entries has no set composition, must have more than one state of matter, must have more than one substance. What mistake did Dominic make? The title should read “Properties of Solutions” because some mixtures do not have all of the properties listed. There is a definite recipe to make each mixture, so the composition of a mixture is set. Although it is possible to have more than one state, it is also possible to have only one state. A single substance can be used to make a mixture if the substance is composed of more than one element.

In DNA replication, the resulting daughter molecules contain one strand of the original parental DNA and one new strand. What is the explanation for this phenomenon
Answer:
This question lacks options, options are: A) DNA replication is semiconservative. B) DNA replication is conservative. C) RNA synthesis is conservative. D) DNA replication is not conservative. The correct answer is A.
Explanation:
Watson and Crick proposed the semi-conservative hypothesis (later demonstrated by Meselson and Stahl in 1957), according to which new DNA molecules formed from an old one have an old and a new strand. This replication model assumed that the double helix DNA separates its two strands and each one serves as a template to synthesize a new strand following the complementary rules of nitrogenous bases. This model was called Semiconservative, since the two newly synthesized double helices have an old strand (an old half) and a new strand (a new half).
The process of the formation of new DNA from the older DNA is called replication.
The answer to the following question is semi conversation of DNA.
In the replication, there are two-strand in which one stand is template strand and the other stand is called leading strand. Both the strands act as a template strand and is being copied by the DNA polymerase.
These template strands formed the new DNA and joined it by the DNA ligase to complete it.
Hence, In DNA replication, the resulting daughter molecules contain one strand of the original parental DNA and one new strand. This phenomenon is known as semi-conservation.

Because the flow speed in your capillaries is much less than in the aorta, the total cross-section area of the capillaries considered together must be much larger than that of the aorta. Given the flow speeds noted, the total area of the capillaries considered together is equivalent to the cross-section area of a single vessel of approximately what diameter
Answer:
Diameter of capillaries is 30-40 µm in diameter while on the other hand, the diameter of aorta is 4 cm.
Explanation:
The diameter of capillaries is 30-40 µm in diameter while on the other hand, the diameter of aorta is 4 cm which is the main reason for higher flow speed of the blood in the aorta as well as more blood is transported in the aorta. If the total area of the capillaries considered together is equivalent to the cross-section area of a single vessel of aorta then the flow speed of both is similar due to similar area.
