Answer:

b. eukaryotes

Explanation:

Eukaryotic cells have a true nucleus, which means the cell’s DNA is surrounded by a membrane. Therefore, the nucleus houses the cell’s DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.

Eukaryotes are the group of organisms that contain a nucleus in their cells. Unlike prokaryotes (which include bacteria), eukaryotic cells are defined by the presence of a nucleus and other membrane-bound organelles.

The organism that contains a nucleus among the given options is the eukaryotes. To explain further, living organisms can be divided into two broad categories: eukaryotes and prokaryotes. Eukaryotes are organisms whose cells contain a nucleus and other organelles enclosed within membranes. Examples of eukaryotes are fungi, plants, and animals. Meanwhile, bacteria and prokaryotes do not have a nucleus. Prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures, including a nucleus.

The answer is A. Differential reproduction.

Answer:

The correct answer is differential reproduction

Explanation:

The different individual in a population tends to produce a different number of offspring and this difference in reproduction among them is called differential reproduction. This differential reproduction is responsible for producing more offsprings by some individuals.

Nature allows those individuals who are better suited in their environment to survive up to reproduction age and produce offspring and many of those individuals who are less adapted do not reach to reproduction age thereby produce less offspring.

B. The plants will make fewer nutrients because of chlorophyll loss.

Explanation:

The surface of the leaf is lined with chloroplasts.

Since the leaf sizes have been reduced, chloroplasts have followed. Thus, there are less chlorophyll pigments, indicating less chances of photosynthesis, meaning fewer nutrients made.

Answer:

The correct answer is option A- the plants will make fewer nutrients because of chlorophyll loss.

Explanation:

Summer is experienced with high temperature and high intensity of light which shows effects on the plant.  

Exposure to high temperature and high light intensity above threshold cause several physiological and morphological changes in the plants like affect the chlorophyll. Chlorophyll gets degraded by a process called " chlorosis" due to which brown and yellow patches start appearing on the leaves.

The chlorophyll loss leads to less production of glucose molecule as the sunlight is not captured by the chlorophyll, a pre-requisite condition of the photosynthesis.

Thus, option- A is the correct option.

Apoximis or asexual seed formation

Apoximis is when a seed will be produced that can turn into a genetically identical plant.

Explanation;

Asexual reproduction is the type of production that results to offspring or organisms that are genetically identical to the parent plant. In plants, plants can reproduce asexually through vegetative reproduction or apomixis, without fertilization of gametes.

Apomixis is where some plants can produce seeds without fertilization. This occurs when an ovule or part of the ovary gives rise to a new seed.

Answer: Point source pollution is water pollution that comes from a direct single source and can easily be traced. Some examples of point source pollution can be oil spills, sewage drainage pipes, unlined landfills

Point source pollution occurs when pollutants enter an aquatic ecosystem from a single identifiable location, such as sewage discharges, leading to problems like eutrophication and harm to aquatic life.

Point source pollution of an aquatic ecosystem refers to contaminants entering the environment from a single, identifiable source. Examples include discharges from wastewater treatment plants, factories, and combined sewers. During heavy rain, combined sewer systems may overflow, leading to direct spilling of untreated sewage into water bodies.

Eutrophication is another consequence of point source pollution, wherein excessive nutrients, such as nitrates and phosphates from waste, promote overgrowth of algae and bacteria. This leads to oxygen depletion in the water, adversely affecting fish and other aquatic life. Ocean acidification is a separate issue where excess CO2 in the atmosphere causes oceans to become acidic, which can harm corals and shellfish. In addition to chemicals, physical debris can also be a point source of pollution, posing dangers to aquatic wildlife.

Final answer:

Birth rates versus death rates, immigration, and emigration are primary factors affecting population growth rate. Local site-level factors, including resource availability and demographic processes, also significantly impact population dynamics and can influence larger scale trends.

Explanation:

A major factor affecting population growth rate is the balance between birth rates and death rates, alongside immigration and emigration. If the birth rate exceeds the death rate, the population will grow, whereas the population will decrease if the reverse is true. When birth and death rates are equal, the population size remains stable. Additional factors influencing population size include resource availability, environmental conditions, such as droughts, and biotic factors like predation, parasitism, and competition.

The labor market and economic factors such as GDP can also reflect changes in population size. Populations are affected significantly by factors at the site level, encompassing local resources and demographic processes, which can in turn influence larger scale population dynamics.

Answer:

c. The population will decrease due to lack of resources

The decrease in the number of trees most likely to affect this bird population. The effect caused is the population will decrease due to lack of resources. The correct option is c.

The Acid rain Is a form of precipitation which has acidic components like sulfuric or nitric acid. This falls on the ground from the atmosphere in wet or dry forms which includes rain, snow, fog, hail, acidic in nature.

The acidic rain would decrease the number of trees. In return, the birds or animals whose habitat is the large trees and plants, may not survive there. These animals or birds will change their habitat in order to fulfil their survival needs.

Thus, population will decrease due to lack of resources. The correct option is c.

A brood nurse in biology is a member of a social insect colony responsible for the care of the young, having specific adaptations for tasks such as feeding, grooming, and protecting the larvae and pupae.

The term "brood nurse" refers to certain members of social insect colonies, such as ants, bees, and wasps, that are responsible for the care of the young, which is known as the brood. These nurse workers have specific physiological and behavioral adaptations that enable them to perform tasks such as feeding, grooming, and protecting the larvae and pupae. For instance, in honeybee colonies, nurse bees feed the larvae with a substance produced in their hypopharyngeal glands, known as royal jelly or worker jelly, depending on the larva's diet, which will determine its development into either a queen or worker bee.

The reasoning used is inductive reasoning.

The type of reasoning where the examples are used to derive conclusion it is called as inductive reasoning. The end is the theory or plausible. This implies the end is the piece of thinking that inductive thinking is attempting to demonstrate. Inductive thinking is likewise alluded to as 'circumstances and logical results thinking' or 'base up thinking' since it looks to demonstrate an end first. This is normally gotten from explicit occasions to build up a general end.

As the given examples quotes many examples of desert and then derives conclusion out of it, this is considered as example of inductive reasoning.

Final answer:

The term 'vibrio' is used to refer to a prokaryotic cell that is comma-shaped, distinguishing it from other bacterial shapes such as coccus (spherically shaped) and bacillus (rod-shaped).

Explanation:

In the context of bacterial shapes, when referring to a prokaryotic cell that is comma-shaped, the term that is used is vibrio. Bacteria are categorized into different shapes primarily based on their cellular morphology. For instance, coccus (pl. cocci) is a term for spherical-shaped cells, while bacillus (pl. bacilli) is used for rod-shaped cells. When bacteria present a curved rod shape, it indicates a vibrio, which are rods with a single curve, as opposed to spirillum or spirochetes that have multiple curves or a spiral shape. Therefore, the type of bacteria that is comma-shaped is called vibrio.

Ecosystem stability on the concepts of equilibrium, resistance, and resilience. These factors, along with biodiversity and disruptions to food chains and food webs, can influence whether an ecosystem remains stable or undergoes destructive or irreversible changes.

The stability of an ecosystem can be determined using factors such as its equilibrium, resistance, and resilience. Equilibrium is the steady state of an ecosystem where all organisms are in balance with their environment and with each other. Resistance is the ability of an ecosystem to remain at equilibrium in spite of disturbances, and resilience is the speed at which an ecosystem recovers equilibrium after being disturbed.

When considering human impact, ecosystem resistance and resilience become especially important. Changes in these parameters can lead to changes in ecosystem structure and cause the ecosystem to lose its resilience entirely. This, in turn, can result in the complete destruction or irreversible altering of the ecosystem. Other factors that can affect ecosystem stability include biodiversity and disturbances whether they are internal or external.

Food Chains and Food Webs

Food chains and food webs model the flow of energy and materials between organisms within an ecosystem. Changes in the structure or dynamics of these food chains and webs can also impact the stability of the ecosystem.

The stability of an ecosystem is determined by its resistance (ability to maintain equilibrium despite disturbances) and resilience (the speed of recovery after disturbances). Ecosystem dynamics study these changes. Biodiversity, food chains, and food webs are key factors in influencing an ecosystem's stability.

The stability of an ecosystem is determined by its equilibrium, which is a dynamic state in which changes in species numbers and occurrences are balanced, thus maintaining a certain level of biodiversity. This balance, however, can be disturbed by both external and internal factors. The ecosystem's resistance, its ability to remain at equilibrium despite disturbances, and its resilience, the rate at which it recovers equilibrium after being disturbed, are especially important in measuring changes in ecosystems.

Major disturbances or alterations in the ecosystem could lead to a situation where it loses its resilience entirely, leading to either complete destruction or irreversible altering of the ecosystem. The study of these changes in ecosystem structure caused by environmental changes (disturbances) or by internal forces is called ecosystem dynamics.

Furthermore, the diversity of species within an ecosystem also influences its stability. The food chains and food webs are a part of the ecosystem that showcases the interaction between species and the transfer of energy from one species to another. This further affects the stability of an ecosystem.
