Population growth, requires two core assumptions: birth and death rate, which will acount for population growth and decrease, respectively. As medicine develops, it is expected that there will be more succesful births, and that death rate will decrease. Regarding death rate, lifespan predictions are important factors that are required for population growth. Lifespan predictions might vary between countries, since income and country development are important issues influencing population lifespan.

Answer:

Snow is better than flooding.

Explanation:

Snow and flooding are two weather conditions that are come from water. Snowing is considered to be a regular weather condition that often happens in winter, but flooding is considered to be a disaster.

Flooding does more damage to our society. Plenty of accidents such as nuclear station shutdowns are caused by floods and other water-related disasters. Snowing, on the other hand, is only annoying since you have to go outside in the cold shoveling snow, only to find your driveway completely full of snow the next day.

The correct match of the ecology terms with their definitions is as follows:

Ecology is the branch of biology dealing with the relationships of organisms with their environment and with each other.

Some ecological terms were given in this question and are described as follows:

Abiotic factors are nonliving, inanimate, characterised by the absence of life; of inorganic matter.

Renewable resources are natural resources that is replenished by natural processes at a rate comparable to its rate of consumption by humans or other users.

Heterotrophs are organisms which requires an external supply of energy in the form of food as it cannot synthesize its own.

Decomposers are organisms that feed off decomposing organic material, especially such a bacterium or fungus.

Biotic factors are those pertaining to, or produced by life or living organisms.

Scavengers are animals that feeds on decaying matter such as carrion.

Population is a collection of organisms of same species, sharing a particular characteristic of interest, most often that of living in a given area.

Omnivore is an animal which is able to consume both plants (like a herbivore) and meat (like a carnivore).

Limiting factor is a condition that limits the growth or abundance of a population of organisms in an ecosystem.

Ecosystem is the interconnectedness of organisms (plants, animals, microbes) with each other and their environment.

Herbivores are organism that feeds chiefly on plants; an animal that feeds on herbage or vegetation as the main part of its diet.

Invasive species are species that has been introduced to an environment where it is not native, and that has since become a nuisance through rapid spread and increase in numbers, often to the detriment of native species.

Carnivore is an organism that feeds chiefly on animals; an animal that feeds on meat as the main part of its diet.

Autotroph is any organism that can synthesize its food from inorganic substances, using heat or light as a source of energy.

Oldfish are poikilothermic organisms. Their body temperature varies when the environmental temperature changes. Therefore, their metabolic rate should be easier to manipulate compared to homeothermic organisms. Therefore the correct option is d. poikilothermic; varies; metabolic; homeothermic.

Oldfish are poikilothermic organisms, meaning their body temperature varies with changes in the environmental temperature. Unlike homeothermic organisms that maintain a relatively constant body temperature, oldfish's internal temperature fluctuates in response to their surroundings. This characteristic allows them to adapt to different thermal conditions.

Due to their poikilothermic nature, oldfish have a variable metabolic rate. Their metabolic activity increases as the environmental temperature rises and slows down when the temperature decreases. This flexibility in metabolic rate makes it easier to manipulate their energy expenditure and overall physiological processes by controlling the surrounding temperature.

In contrast, homeothermic organisms, such as mammals and birds, maintain a stable internal body temperature regardless of the external environment. Their metabolic rate remains relatively constant and independent of environmental temperature.

Understanding the distinction between poikilothermic and homeothermic organisms helps researchers and scientists comprehend the thermal biology, energy requirements, and ecological adaptations of different species.

A )loss of ADH secretion.

Destruction of the supra-optic nucleus of the hypothalamus can cause loss of ADH secretion. Reason behind this is antidiuretic hormone are synthesized in hypothalamic supra optic nerves .Hence, destruction of supra optic nerve in the hypothalamus will alter the production and secretion of ADH . ADH is stored in posterior pituitary gland and is released into the circulation in response to extracellular fluid changes by the osmoreceptors in the brain.

Deficiency of ADH can cause or insensitivity of the kidney to ADH also known as nephrogenic diabetes insipidus. These patients, if untreated, have the predictable result of dehydration, hyperosmolality, hypovolemia, and eventual death in severe cases.

Harry Harlow's 1959 study demonstrated that attachment in rhesus monkeys was related to contact comfort, rather than just food provision. This finding challenged the previously held belief that infants primarily form attachments based on the caregiver's ability to provide nourishment.

In Harlow's experiments, baby rhesus monkeys were separated from their mothers and placed with two surrogate mothers, one made of wire and the other covered in soft cloth. Both surrogates were equipped with feeding mechanisms, but only the cloth-covered surrogate provided the sensation of touch and comfort. The monkeys overwhelmingly preferred the cloth-covered surrogate, spending most of their time with it and seeking it out for comfort during times of stress. This demonstrated that the physical comfort and warmth provided by the surrogate were more important for the development of attachment than the mere provision of food.

Harlow's research had significant implications for understanding the importance of emotional and physical connection in the development of infant-caregiver relationships. It emphasized the critical role that contact comfort plays in the formation of secure attachments and healthy emotional development. Harlow's work also contributed to improvements in childcare practices, emphasizing the importance of affectionate touch and emotional support for infants and young children.

Answer: The reason for the increased number of drug-resistant bacteria being found in hospitals is due to MISUSE and OVERUSE of antibiotics.

Explanation:

Antibiotics is a type of drug that attacks bacteria microorganisms either by killing or eliminating the bacteria (that is, bactericidal) or by preventing further growth of the bacteria (that is, bacteriostatic). Antibiotics should be taken properly while being used to treat any diseases condition to prevent drug resistance by the bacteria from occurring.

The reason for the increased number of drug-resistant bacteria being found in hospitals is due to MISUSE and OVERUSE of antibiotics. This causes the bacteria to change the way they respond to these medicines making them become antibiotic resistance. When they infect an individual, the infections they cause are harder to treat than those caused by non-resistant bacteria.

This prompt is about locating the epicenter of an earthquake. In seismology, the epicenter, epicentre, or epicentrum is the point on the Earth's surface directly above a hypocenter or focus, where an earthquake or subsurface explosion starts.

When an earthquake happens, it sends out waves that travel through the ground, and we can measure those waves using special machines called seismographs. To find out where the earthquake happened, we need to use data from at least three seismograph stations that recorded the earthquake.

We start by looking at the time it takes for different waves to reach each station. First, we look at the arrival time of the primary (P) wave, which travels faster and arrives first. Then, we look at the arrival time of the secondary (S) wave, which is slower and arrives second. We calculate the time difference between the arrival of the P and S waves at each station.

Next, we use the time difference to figure out how far away the earthquake was from each station. We use a special formula to do this, which takes into account how fast the waves travel through the Earth's crust.

We then plot the distance from each station on a map, creating circles around each station with the distance as the radius. Where the three circles overlap is the epicenter of the earthquake. This is the point on the Earth's surface directly above where the earthquake started.
