3. When a single-celled organism splits into 2 new organisms it is called _________________. *

a.fission
b.budding
c.fragmentation
d.sporulatioin

Answer/Explanation:

In humans, we breathe in oxygen via the respiratory system. The oxygen enters the lungs. The air sacs in the lungs - the alveoli - are the site of gas exchange in the lungs and are where the circulatory and respiratory systems interact.

The alveoli take in the oxygen, where it diffuses into the capillaries (circulatory system). Blood, which passes through the capillaries takes this oxygen to all the cells in the body. Oxygen binds to haemoglobin in red blood cells, which transport it around the body.

Additionally, blood also transports carbon dioxide back to the alveoli of the lungs, where it diffuses into the lungs and is expelled when we breathe out

The vaccine recommended much more frequently than others is option  C. Viruses constantly change, creating variants that may not be affected by the previous year's vaccinations.

The influenza vaccine is recommended more often than other vaccines because the flu virus is known to mutate regularly and rapidly. As a result, even a strain that has been circulating for a few years can mutate to a completely new form, rendering existing vaccines ineffective.

Influenza viruses mutate through a process known as antigenic drift, which happens when the virus's outer layer changes over time. Since our immune system is not equipped to detect these new structures, it may not be able to produce the necessary antibodies to combat the new influenza strain.

As a result, an influenza vaccine that was effective last year may be completely ineffective this year, leaving people susceptible to the new strain. As a result, doctors advise people to get a flu shot every year to ensure that they are protected from the most recent strain of the virus.

The vaccine, on the other hand, can aid in the prevention of the most prevalent and potentially lethal strains that are currently circulating. Therefore, people need to receive a flu vaccine on a yearly basis in order to protect themselves against new strains of the virus that emerge every year. The correct answer is option c.

Answer:

If a major predator was added to a food web, it could have a variety of impacts depending on the specific species and ecosystem in question. Some potential outcomes could include:

Changes in population dynamics: The addition of a major predator could lead to changes in the populations of other species in the food web. For example, if the predator preys on a particular species, that species may decline in population, while other species that are not preyed upon may increase in population.

Trophic cascades: The addition of a predator can also lead to trophic cascades, where changes at one level of the food web ripple down to other levels. For example, if a predator reduces the population of a particular prey species, this could lead to changes in the populations of species that depend on that prey species for food.

Ecological balance: The addition of a predator could potentially restore balance to an ecosystem if it is introduced to control an overabundant prey species. This can help to prevent overgrazing or other negative impacts on the ecosystem.

Extinction risk: In some cases, the addition of a major predator could pose a threat to other species in the food web, potentially leading to extinction if the predator preys on a vulnerable species.

The problem of quagga mussels in the lake is an ecological issue that requires scientific assessment and management.

It falls under the discipline of ecology, which studies the relationships between organisms and their environment.

Ecologists investigate the impacts of invasive species on the ecosystem and devise strategies to control their spread and minimize their effects.

In this case, scientists will need to examine the size of the quagga mussel population, their distribution, and their ecological interactions with native species.

They will also need to recommend measures to prevent further introduction of quagga mussels and to manage their population growth, such as using chemical treatments or biological controls.

Explanation:

Answer: Organisms interact with other organisms for a variety of reasons, including:

To obtain food: Many organisms interact with each other to obtain food. Predators hunt and kill prey, herbivores graze on plants, and scavengers feed on the remains of dead organisms.

To reproduce: Sexual reproduction requires interaction between individuals of the same species. Pollination and fertilization are examples of interactions between plants and animals that result in reproduction.

To defend against predators: Many organisms interact with others to defend themselves against predators. Some animals form herds or groups to confuse predators, while others have developed defensive adaptations such as camouflage or poison.

To facilitate survival: Some organisms interact with others to improve their chances of survival. For example, some birds forage together, which increases their chances of finding food and reduces the risk of predation.

To obtain other resources: Organisms may interact with others to obtain resources other than food, such as water, shelter, or nesting sites.

The way that  lichen differ in its photosynthetic activity from Elysia chlorotica, the sea slug that’s considered to be a photosynthesizing animal is option C. Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells.

In a lichen, the algal partner is responsible for photosynthesis, and the fungal partner provides protection and structure for the algal cells. The relationship between the two organisms is permanent and essential for the survival of the lichen.

On the other hand, Elysia chlorotica, a sea slug is considered to be a photosynthesizing animal. It incorporates chloroplasts from the algae it feeds on and retain them, which allows it to carry out photosynthesis on its own. This mechanism is not a permanent association and the slug can photosynthesize only when it has the chloroplasts.

A lichen is an organism that structurally appears to be a single organism. But a lichen is actually two different organisms—a fungus and green algae—living together as one organism. The fungal partner derives its nutrition from the photosynthesizing algae. How does a lichen differ in its photosynthetic activity from Elysia chlorotica, the sea slug that’s considered to be a photosynthesizing animal?

A.

In lichens, the fungi photosynthesize on their own, while Elysia chlorotica forms a relationship with a photosynthesizing plant.

B.

In lichens, the relationship with the algae lasts throughout the life cycle, but in Elysia chlorotica, the relationship occurs only during the immature juvenile stage of the slug’s life cycle.

C.

Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells.

Explanation:

Answer:

Reproductive isolation is the inability of individuals from different species to produce viable offspring. There are several mechanisms of reproductive isolation. Here are three examples:

Answer: Three major structural or functional similarities between frogs and humans:

Skeletal Structure: Both frogs and humans have a skeletal system that provides support and protection for their bodies. While frogs have a more simplified skeletal structure compared to humans, both have bones that serve similar functions.

Nervous System: Frogs and humans have a complex nervous system that allows them to sense and respond to their environment. Both species have a brain and a spinal cord, which are crucial for coordinating various bodily functions and facilitating movement.

Digestive System: Frogs and humans have similar digestive systems. They both have a mouth, esophagus, stomach, and intestines, which are involved in the process of breaking down food and extracting nutrients. Additionally, both species have specialized organs such as the liver and pancreas that aid in digestion.

Three major structural or functional differences between frogs and humans:

Respiratory System: Frogs have a unique respiratory system that allows them to breathe through their skin. They can also respire through their lungs and the lining of their mouth. In contrast, humans rely solely on their lungs for respiration, exchanging oxygen and carbon dioxide through the alveoli.

Reproductive System: Frogs have external fertilization, meaning that the female lays eggs and the male fertilizes them externally. Humans, on the other hand, have internal fertilization, where the male's sperm fertilizes the female's egg inside her body. Additionally, frogs undergo metamorphosis, transforming from tadpoles to adults, while humans do not experience this drastic change.

Locomotion: Frogs are adapted for a life both on land and in water, with their specialized limbs and webbed feet that allow them to jump and swim efficiently. Humans, on the other hand, have a bipedal locomotion, relying on two legs for walking and running. Humans have a more upright posture and a different skeletal structure to support their mode of locomotion.

It's important to note that while frogs and humans share certain similarities and differences, these examples are not exhaustive and there are many more intricate details that differentiate the two species.
