Explanation:

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.

Object is moving away from observer.

Explanation:

If a force is applied to an object it starts moving. The object will move towards the observer, this is known as Doppler effect. It is when an observer or the thing under observation moves. There is change in its position due to a force exerted on it. The motion of the object also depends on the direction of force.

Answer:

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:

Ecological footprint estimates the requirements of renewable resources that a population consumes to live a particular lifestyle. Some ecologists are concerned because the result of the ecological footprint shows that the  demand of the population is increasing in comparison to the supply of nature.

For example in India, the ecological footprint shows negative impact of population demand over supply of nature.

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.  

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.

Answer:

Axon terminal ; dendrite

Hope this answer correct :)

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.

INCREASES.

As human travel increases(As humans move from one place to another),the number of introduced species likely increases because as humans move from one place to another,they introduce new species of organisms to their new environment.

These non-native species grow in this new environment,becomes economically important and doesn't pose any harm to their new ecosystem unlike invasive species that poses a substantial harm.

The number of introduced species are likely to : ( B ) Increases

As Humans migrate from one place to another they introduce new species into their new environment naturally or artificially.

The movement of humans or any type of organism comes with the introduction of new species because as they move they take along with them certain species that naturally do not belong to their new environment.

Hence we can conclude that As human travels The number of introduced species are likely to Increase.

The correct answer is option A "Duplication".

Explanation:

Chromosomal duplication is defined as a type of rearrangement of genetic material at which extra copies of a DNA fragment are created. In this case if a broken chromosomal fragment becomes reattached, this fragment will represent an extra copy, and therefore the resultant genetic material is considered a chromosomal duplication.

Have extra set of chromosomes compared to other species that have the same but fewer set is being called polypliod organisms are constantly under assault from their environment. Having extra set of chromosomes make them better able to cope with the pressures that thretend to wipe them out.

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.

Environmental education includes the study of various factors of the environment which affect the health of human beings. Environment comprises all the factors in our surroundings. It includes even abstract factors , which do not have weight , length and breadth. Cultural traits , social norms and values, feasts and festivals etc. are some of the examples of abstract aspects. Some of the scopes of environment education are described below:

The physical aspect included non- living things on the earth. They are soil, water , air , rocks , gases etc. Environment education gives knowledge about the status of soil , water , air , rocks , gases and other various physical components of the earth. It aims to make students aware of the effects and consequences of human activities upon these factors. It also gives knowledge to raise environment friendly attitude and behavior among the students .

The biotics factors include living plants and animals , their life mechanism , interrelationship etc. Some of the educational streams related to the biotic aspects are biology , agriculture , and forestry. They are some of the important scopes of the environment education. This branch of education helps to develop the level of knowledge , attitude and behavior regarding these factors in the students.

Environment has some of the abstract aspects too. Abstract aspects include religious , cultural , ethnic and social norms and values. Some of the educational streams dealing with this aspect are sociology , civics and anthropology. Environment education also teaches students about such abstract factors, which play vital role in the environment.

[tex] \bold{ \green{Scope \: of \: Health \: education}}[/tex]

In general , scope of health education can be understood as the areas included in health education. Health education not only communicates knowledge about body features and diseases, but also includes the matters concerned with healthy surroundings , human psychological states affecting health , public health, human anthropology , medical science and so many other things. Any three scopes of health education are as follows:

Home is the residence of all people. Home is the first school for all. A child passes the primary days of life at home. Every individual learns the basic skills if survival at home. Proper time to wake up in the morning , to start daily sanitary schedules, to eat , to practise all other health behavior are learnt at home. The child lives in community and learns many more about healthy social adjustment in the social environment. Health education aims to raise the level of knowledge , attitude , and behavior related to health and healthy life.

Children go to school for formal education and spend most of active hours of a day. They achieve several forms of health knowledge and develop healthy attitude and practise accordingly. Their heath status depends upon the environment of school , health curriculum, healthful school environment , co-curricular and extra - curricular health activities.

Community is a place where many people live with their families. People's health is determined by the several factors in the community. Health education teaches about these factors like community sanitation , drainage , health service providing organizations and health centers.
