Answer:

These seven methods include: seed propagation, cutting, layering, division, grafting, budding, and tissue culture technique.

Explanation:

The major methods of asexual propagation are cuttings, layering, division, budding and grafting. Cuttings involve rooting a severed piece of the parent plant; layering involves rooting a part of the parent and then severing it; and budding and grafting is joining two plant parts from different varieties.

Answer:

Explanation:

Explanation:

The real magnitude of this challenge can perhaps be best judged by considering the structural and functional complexity of the human brain and the bewildering complexity of human behavior. The human brain is thought to be composed of about a hundred billion (1011) nerve cells and about 10 to 50 times that number of supporting elements or glial cells. Some nerve cells have relatively few connections with other neurons or with such effector organs as muscles or glands, but the great majority receive connections from thousands of other cells and may themselves connect with several hundred other neurons. This means that at a fairly conservative estimate the total number of functional connections (known as synapses) within the human brain is on the order of a hundred trillion (1014). But what is most important is that these connections are not random or indiscriminate:

They constitute the essential "wiring" of the nervous system on which the extraordinarily precise functioning of the brain depends. We owe to the great neuroanatomists of the last century, and especially to Ramón y Cajal, the brilliant insight that cells with basically similar properties are able to produce very different actions because they are connected to each other and to the sensory receptors and effector organs of the body in different ways. One major objective of modern neuroscience is therefore to unravel the patterns of connections within the nervous system—in a word, to map the brain.

This question lacks options, options are:

a.Fatigue fracture

b.Stress fracture

c.Pathologic fracture

d.Greenstick fracture.  

The correct answer is c.

Explanation:

A pathological fracture is one produced in a weakened bone as a result of trauma that would not cause such an effect on bones that had their composition, resistance or flexibility properties at the correct levels, that is, a pathological fracture is any loss of bone continuity that occurs in a weakened bone, secondary this weakness to the development of a disease. Endogenous osteomyelitis is a blood-borne bacterial infection that spreads to the bone.

Answer:

This question lacks options, the options are;

A. Enlarged molecules

B. Macromolecules

C. Inorganic molecules

The answer is B

Explanation:

As mentioned in this question, carbohydrates, proteins, lipids, and nucleic acids are the basic biomolecules found in nature. They are all polymeric substances, hence, are made up of smaller units called monomers.

Asides from being biomolecules, these four molecules are also referred to as MACROMOLECULES based on their large size and complex nature. Macromolecules are molecules that are relatively large in size composing of an aggregate of monomer. Hence, these biomolecules are macromolecules.

Answer:

Saliva

Explanation:

Answer:

coexistence is possible if each species is more efficient at using a different resource than the other species.

Explanation:

Competition is an ecological and evolutive process very common in nature. Competition might be intra- or interspecific. Competition between different species in a community or ecosystem might be due to the same resource use, or the same territory, shelter, etcetera. When a resource is useful for two or more species, and limited, they compete to gain it.

The principle of competitive exclusion states that different species with the same requirements sharing the niche can not coexist indefinitely based on the same limited resource. When two competing species coexist, this is because of niche partitioning or niche differentiation.

Differentiation of effective niche is closely related to character displacement.

Character displacement is the result of interspecific competition, in which two or more species that live in the same habitat manage to avoid competition by developing different traits. Morphological divergence, or any adaptative trait development, fixated genetically, is the product of niche segregation. Species tend to differentiate morphologically in the presence of strong competitors. Traits divergence favors coexistence in the same place.

In the exposed example, both species have different abilities to utilize different levels of multiple resources. If both species live in the same place, this ability is significant to avoid competition and competitive exclusion.  

Answer:

PHOTOSYNTHESIS is a process in which green plants and other certain organisms convert water, carbon dioxide and other minerals into energy rich molecules and oxygen using the light energy.

Answer:

Photosynthesis is a process through which plants and other organisms transform light energy into chemical energy, which is then released to power the organism's activities through cellular respiration.

Flowers that bloom in different months is an example of temporal isolaton.

Temporal isolation is a type of reproductive isolation that occurs when two or more species reproduce at different times, thereby preventing mating between them. This can happen in a variety of ways, such as when one species is active during the day and the other at night, or when they breed during different seasons.

Temporal isolation can lead to the evolution of new species because it prevents interbreeding between populations that would otherwise exchange genetic material. Over time, these isolated populations can accumulate genetic differences that make it increasingly difficult for them to interbreed, leading to the formation of distinct species that are reproductively isolated from one another.

Explanation:

Provide suitable place where they can breed without disturbance, making laws to forbit hunting of endangered species and reduce pollution are the different methods that can protect endangered species of animals and plants around the world. For increase in population, suitable environment is required so that they have no predators or other factor that adversely affect their growth. The laws to forbit hunting or killing has also a significant effect on endangered species. Pollution is the main reason for change in the environment that make the environment not suitable for animals and plants.

Answer:

To help conserve water or prevent loss via transpiration from the leaves

Explanation:

Some plants are found growing in habitats with little or no moisture content as annual rainfall is very low. These plants are called xerophytic plants. However, despite the low water condition, these plants are adapted to the environment and still survive.

One of their adaptation (structural) is that their leaves are reduced to thorns. Ideally, plants tend to lose water via the stomata on the leaves in a process called TRANSPIRATION. Hence, the leaves of plants adapted to a xerophytic habitat is modified to thorns in order to prevent water loss from the leaves and conserve the water.

Answer:

A

Explanation:

The correct answer would be option A - GUA-CAU-ACC

Looking at the table of codons, for the amino acid Val, the first base (which is on the 1st column in the 6th row) is G while the second base (2nd column, 2nd row) is U. The third column can be any of U, C, A, or G (6th column, 4th row). Hence, GUA is plausible

For the amino acid His, the first base is C (1st column, 2nd row), the second is A (4th column, 4th row) while the last could be any of the 4 bases. Hence, CAU is plausible.

For the amino acid Thr, the first base is A (first column, 5th row), the second is C (3rd column, 2nd row) while the 3rth could be any of the 4 nucleotide bases. Hence, ACC is plausible.

Therefore, the correct sequence of nucleotides for Val-His_Thr would be GUA-CAU-ACC

Paralogous genes are a class of homologous genes which are due to the duplication of gene, then this are refered to as paralogous.

Genes for the oxygen-carrying proteins hemoglobin and myoglobin descend from a common ancestor but act in very distinct ways today. They are referred to as paralogous.

Answer:

Cytoplasmic inheritance

Explanation:

From these crosses, we can notice that only the female´s phenotype is expressed in the progeny, independently of the male´s phenotype. Whenever this occurs, it is probably due to the action of cytoplasmic inheritance.

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. Even though most of the DNI is located in 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.

When a female expresses a trait that is defined by genes in the organelles, the whole progeny expresses the same trait as the female.

Mitochondrial inheritance is mostly maternal, but recent studies have demonstrated that it might also be paternal.  

The described experiment is an example of Cytoplasmic inheritance.

Phenotypes may be defined as the appearance or manifestation of a character. Phenotypes are also known as traits.

Cytoplasmic inheritance reveals the phenotypes of offspring according to female parents. In this mode of inheritance, characters or traits are stored in the organelles like chloroplast, and mitochondria, as well as in the cytoplasm.

Therefore, the described experiment is an example of Cytoplasmic inheritance.
