Answer:

c) Organisms within a population vary, and all populations produce more offspring than can be supported by the environment, resulting in competition for survival within the population.

Explanation:

Darwin's theory was based on the evidence of natural selection and survival of the fittest.

Evidence of Darwin's theory were observed from the variation in the population which is supported by the environmental factor (natural selection) and these population than produce offspring, resulting in competition for survival within the population (survival for fittest).

Hence, the correct option is "c".

Answer:

The primary function of the lymphatic system is defending the body against both external and internal threats.

Explanation:

The set of tissues and organs that participate in the immune response is known as the lymphatic system. Its main functions are to maintain the volume of blood and participate in the defense of the organism. It is made up of organs, vessels, nodes and lymphatic tissue. This system fulfills three basic functions: Defense: in the lymph nodes, the lymphocytes reproduce to respond to antigens; fat absorption: most of the fats are absorbed by the lymphatic system and subsequently transported to the blood and capillary exchange: it recovers substances that the blood flow has lost in the capillary exchange.

The principal function of the lymphatic system is to remove strange or damaging substances from tissues and eliminate them. The correct option is defending the body against both external and internal threats.

------------------------------

Among other functions of the lymphatic system, its principal one is the removal of damaged cells, cancer cells, and protection of the body against the virus, bacteria, and fungi that might affect it.

The lymphatic system remove these elements from the tissues for their elimination.

All these strange microorganisms and waste substances get filtrated in the lymphatic ganglia.

Ganglia are small organs located all along with the net of lymphatic vessels, that function as lymph accumulation centers.

Lymph passes through these organs and gets filtrated and purified of waste substances.

Inside each ganglion, the lymphocytes T and lymphocytes B help the organism to fight these infections.

B cells produce antibodies that impede infection propagation by trapping the microorganisms and destroying them.

Most lymphatic ganglia are grouped near the neck, underarm, and groin.

They are also grouped in the chest, abdomen, and pelvis, where they filter blood.

Answer and Explanation:

The ecologists MacArthur and Wilson took the term island biogeography theory to refer to the predictions about the number of species that could be inhabiting on an island.  

Island biogeography theory establishes that the two factors that affect species richness in natural communities on an island are the distance from the mainland and the size of the island.  

At the same time, these factors affect inmigration and extinction rates. According to the theory, islands that are closer to the continent have higher possibilities of receiving immigrants than those islands that are located farther from the mainland. This is the effect of distance.  

The effect of size is reflected in the relation between island size and species diversity. In smaller islands, the probability of extinction is higher than in bigger islands. Bigger islands can have more species than smaller ones.  

In the case of two islands of the same size and different distance to the mainland, both of them will have the same extinction rate, but the one closer to the continent will have a higher immigration rate, and so, a higher amount of species. The S value will be higher on the island closer to the continent.

Experiment:

To prove that the observations about the species richness and its relation to island size and distance to the continent were not a casualty, manipulation experiments were developed. These experiments helped to prove how the colonization process take place from cero. To observe the entire process of ecological succession and the tendencies proposed by the island biogeography theory Wilson and Simberloff (1970) eliminated the fauna on some islands to observe how they were recolonized from the continent. They fumigated the mangler island and studied these islands to account for the variation in arthropod richness over time. They studied many islands classified by distance. On each island, the richness increased at different rates.  The island closest to the continent received more immigrants and is colonized faster than the other ones, reaching its original richness faster. The farthest island was recolonized but at a much lower rate and it does not reach equilibrium while the study was going on. Although, it was expected to reach equilibrium with time.

Neuron A communicates with neuron B, and the axon terminal of neuron A releases a signal that activates the receptors present on neuron B. The neurotransmitters are attached to the ligand-gated channel on neuron B.

The nerve impulse transmission takes place between two neurons, and then in this way, from the sensory organs, the message passes to the spinal cord and the brain. The synapse is formed between the two neurons, such as the presynaptic neuron that releases the neurotransmitters, and this activates the ligand-gated channel of the postsynaptic neuron. Due to this interaction, the neurons get excited and activated.

Hence, neuron A communicates with neuron B, and the axon terminal of neuron A releases a signal that activates the receptors present on neuron B. The neurotransmitters are attached to the ligand-gated channel on neuron B.

Answer:

4, based on the assumption that the R allele is dominant over the r allele, and that the T allele is dominant over the t allele.

Explanation:

Any bush with a dominant petal color allele (R) will have red petals. This includes Rr and RR.

Any bush with a dominant bush size allele (T) will have a tall bush. This includes Tt and TT.

The only way to acquire a short bush or pink petals is to have two recessive alleles together (tt, rr).

RRTT, RrTT, RRTt, and RrTt -> red petals with tall bushes

RRtt, Rrtt -> Red petals with short bushes

rrTt, rrTT -> pink petals and tall bushes

rrtt-> pink petals with short bushes.

These are the four phenotype variations possible in this dihybrid cross.

Viruses are not cells; they are a strand of genetic material within a protective protein coat called a capsid. They infect a wide variety of organisms, including both eukaryotes and prokaryotes. Once inside the cell, they use the cell's ATP, ribosomes, enzymes, and other cellular parts to replicate.

The characteristics that a virus cell possess with eukaryotic cell is that they both possess a genetic material.

An eukaryotic cell is a cell that has a genetic material bound by membrane-bound nucleus.

A virus cell, on the other hand, is a cell that is incapable of replicating itself without a living host.

However, one similarity between the eukaryotic cell and viral cell is that they both possess a genetic material that stores their genetic information.

A. genotype

B. adaptation

C. selective pressure

D. stabilizing pressure

The answer is B) Adaptation

Explanation:

Adaptation is the process whereby an organism becomes well suited to survive in its natural environment, which is aided by the possession of certain traits called adaptive features. For example, the fins of a fish makes it fit to survive in an aquatic environment, likewise the opposable thumbs of humans make us well suited to survive in our environment.

As stated in the question, the opposable thumb i.e. movement of the thumb independently of the other four fingers, is a characteristics of primates. This unique feature (opposable thumb) allows us to grab things, get a good grasp of tools, use tools effectively, write things, etc. All these ability due to the possession of opposable thumb increases our chances of survival. Hence, the possession of opposable thumb is regarded as an ADAPTATION

Please find the role of teeth, tongue and saliva in digesting guava below

Explanation:

Digestion is generally the process of breaking down complex food substances into their simplest form. However, as easy as this sounds, there are series of processes that must take place in between to achieve the final result.

Once a food substance like guava enters the mouth (ingestion), it initially gets chewed by the TEETH in order to break it down to smaller masses that can be swallowed. During the process of chewing, the TONGUE helps to move the food around the mouth and later helps push it down the gullet/digestive tract. SALIVA, on the other hand, creates a moisturizing environment for the food to form a Bolus (round mass of food ready to pass down the esophagus). The saliva also contains an enzyme called AMYLASE that helps chemically degrade starch content of the food before passed through the digestive tract.

Answer:

The given blank can be filled with a venule.

Explanation:

A small blood vessel in the microcirculation, which connects the capillary beds to the veins is known as the venules. Various venules combine to form a vein. The walls of a venule are formed of three layers, that is, the inner endothelium formed of squamous endothelial cells, a middle layer of elastic and muscle tissue, and an external layer formed of fibrous connective tissue.  

The size of a venule ranges from 8 to 100 micrometers in diameter and are produced when capillaries come in close association. A venule refers to a small blood vessel that permits the deoxygenated blood high in carbon dioxide and waste products to return from capillary beds to the bigger blood vessels known as veins.
