Answer:

B. Elks attach leaves and grasses to their antlers to help them appear larger

Explanation:

The above option is the correct answer.

As elks appear larger, it tend to make other male elks to be scared to fight that particular elk for a female elk. Also, the female elk becomes more attracted to larger male elk.

Male elk are known to actually retain their antlers for more than half the year. Such elks do not likely group themselves with other males when they have antlers.

Answer:

It is believed that insects are so successful because they have a protective shell or exoskeleton, they are small, and they can fly. Their small size and ability to fly permits escape from enemies and dispersal to new environments. ... In addition, insects can produce large numbers of offspring relatively quickly.

There are a number of important aspects that contribute to the success of the Class Insecta, which includes insects. The factors are their size, thin exoskeleton, reproduction, etc.

First off, because of their modest size and effective body composition, they may occupy a variety of environments and fill a variety of biological niches.

Insects have a thin exoskeleton that allows for flexibility and motion as well as protection and support.

Because of their diminutive size, they can access a variety of microhabitats, cracks, and supplies that larger species cannot.

In addition, insects have remarkable methods and capacities for reproduction. The majority of insects reproduce quickly and give birth to numerous young.

They use a variety of reproductive techniques, such as internal fertilisation and complex courtship rituals.

Thus, the small size, effective body structure, variety of reproductive techniques, flexibility, and resilience of Class Insecta are factors in their success.

Thus, these elements have made it possible for insects to survive in a variety of habitats, use a range of resources, and play essential roles in ecosystems as pollinators, decomposers, predators, and prey.

Answer:             Water pollution also affects the ecosystem – it can cause a phenomenon called eutrophication. This can cause fish and other aquatic organisms to die. Toxic elements dissolved in water can make their way to humans through fish or other aquatic organisms.

Answer:

Excessive nutrients (nitrates) from fertilisers are flushed from the land into rivers by rainwater. Oxygen levels reach such a low point that fish and other organisms suffocate. These nutrients cause increased aquatic plant growth of algae and other plants.

Answerand Explanation:

The regurgitated blood will enter the left chamber of the heart. This is because as the patient's aotic valve is not working properly, it does not close properly, which allows a backflow of blood to occur towards the left chamber of the heart, as this chamber relaxes to be filled with blood pumped by the right camera.

As the regurgitated blood is a pumped blood, we can consider that it will happen, mainly during systole, which is the moment when the heart contracts to pump blood. This contraction will be made with the malfunction of the aortic valve which will cause blood regurgitation.

Answer:

Usually, the catalytic properties of the enzymes are lost and metabolism is halted. Most bacteria grow best around neutral pH values (6.5 - 7.0), but some thrive in very acid conditions and some can even tolerate a pH as low as 1.0. Such acid loving microbes are called acidophiles.

Answer:

b) x: fin

   y: lateral line

   z: swim bladder  

Explanation:

The dorsal fin is found in the dorsal region of the fish body. Depending on the species, there can be one or two dorsal fins. Membranous structures and bony or cartilaginous ratios compose the fins. One of the main functions is to stabilize the body in water, providing equilibrium. When the dorsal fin is erect, it acts as a keel, helping the fish not to turn aside. Fishes also use these fins as protection because the cartilaginous or bony ratios act as spines. The animal uses these spines to defend itself from predators. The morphological variety of dorsal fins in the different species is used in taxonomy.

The Lateral Line is a system or sensory organ composed of special receptors called neuromasts, which can be found all along the lateral region of the animal. The lateral line perceives information from the environment, such as light, sound, or water movement, among others. These signs are translated into nervous messages. The lateral line is useful to detect prey, predators, other animals moving, objects, etcetera. It is significant for intraspecific interaction, especially during swimming motions in schools. The lateral line receives perturbations of short distance, generated by other living beings or by objects. Some studies confirm that the lateral line is also sensitive to chemical stimuli.

The swim bladder is a neumatic sac-like structure filled with gases coming from the blood. Its main function is to allow neutral floating and let the animal in suspension at any depth, with no need for muscular effort. The animal can regulate the size of the bladder. This organ can be found in most pelagic fishes, while the benthonic ones or the ones that actively swim lack it.

Diversity of the community = 2.097

Explanation:

Given:

Number of pitch pines = 134

Number of douglas firs = 24

Number of red pines = 53

Find:

Diversity of the community

Computation:

Simpson's diversity index = N(N-1)/Σn(n-1)

Particular              n n(n-1)

Pitch pine         134       17822

Douglas firs       24 552

Red pine            53  2756

Total       N=211 21130

So,

D= [211(211-1)] / 21130

D = 2.097

Diversity of the community = 2.097

Explanation : Because purebred plants have lighter colored dominence .

Answer:

Answer:

These lungs are primitive and are not as evolved as mammalian lungs. Adult amphibians are lacking or have a reduced diaphragm, so breathing through the lungs is forced. The other means of breathing for amphibians is diffusion across the skin. To aid this diffusion, amphibian skin must remain moist.

Two common respiratory organs of invertebrates are trachea and gills. Diffusion lungs, as contrasted with ventilation lungs of vertebrates, are confined to small animals, such as pulmonate snails and scorpions.

Explanation:

Amphibians utilize gills for breathing early in life, and develop primitive lungs in their adult life; additionally, they are able to breathe through their skin.

Answer:

The correct answer is - B. breaking the bond between the 2nd and 3rd.

Explanation:

ATP molecule is known as cellular currency as it provides energy for cellular functions. ATP released energy when one phosphate group is removed or eliminated by breaking a phosphoanhydride bond. The rebreaking of this bond and removal is known as hydrolysis, and ATP is converted to adenosine diphosphate (ADP).

Breaking the bond between the 2nd and 3rd phosphate groups provides a very high amount of energy. There is also additional energy released when phosphate is removed from ADP to form adenosine monophosphate (AMP).
